application Ser. No. 11/139,603 filed May 31, 2005, which is a
Continuation of U.S. patent application Ser. No. 09/002,349 filed
Jan. 2, 1998 and claims the benefit of Japanese Patent Applications
No. 09-001866 filed in Japan on Jan. 9, 1997, and No. 09-010154
filed in Japan on Jan. 23, 1997, all of which are hereby

BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to an electronic camera, and
more particularly, to an electronic camera that has an operation
instruction mode and/or a diagnostics mode.
[0004] 2. Discussion of the Related Art
[0005] In general, electronic cameras record still images and/or
moving images using image pickup devices. In particular, digital
cameras are popular among a wide range of users because they are
easy to use for taking pictures due to the fact that digital
cameras do not require film developing processes, which are
necessary for conventional cameras employing silver-halide
films.
[0006] The fact that digital cameras are accepted by a wide range
of users implies that there is increasing use of the electronic
camera by those who are inexperienced with not only operation of a
camera but also mechanical operations in general.
[0007] In order to learn how to operate a camera, it is often
necessary to read the operation manual. However, operation manuals
are hard to understand and operators have to locate the necessary
information in the operation manual every time they need help.
Therefore, learning camera operations takes effort and time for
those who are inexperienced with mechanical operations in
general.
[0008] In addition, taking pictures is frequently conducted
outdoors, and therefore users sometimes find themselves in a
situation where they have to carry the operation manuals with them
all the time until they gain the necessary familiarity with the
camera's operations.
[0009] Furthermore, current electronic cameras that record moving
images have not only functions for taking and displaying pictures
but also advanced image-editing functions. In these electronic
cameras, the number of operation buttons increases as the
complexity and sophistication of the functions increase. Therefore,
the operation of the camera is becoming even more difficult. Thus,
learning camera's complicated and sophisticated functions takes an
even longer time.
[0010] Some other aspects of electronic cameras are discussed
below. In general, an electronic camera not only records
photographic images but also processes and edits photographic
images. Because of this, there are a wide variety of usages for
electronic cameras, and opportunities for using electronic cameras
for photographic purposes instead of silver-halide cameras are
increasing. For example, electronic cameras are used for
picture-taking on family trips and at school events. Since there is
no second chance to take pictures for these trips and school
events, camera users tend to feel anxious about whether the camera
is working properly.
[0011] To cope with this issue, conventional electronic cameras are
equipped with a liquid crystal display (LCD) screen so that
operators can check the image during and/or after picture taking.
However, with this limited confirmation of camera operations during
and/or after the photo shooting, there is a large possibility that
even if the camera is broken, a user does not notice the problem
and starts shooting pictures.
[0012] Idealistically, it is desirable that users check the camera
every time they take pictures by conducting a test shooting before
they actually start taking pictures to ensure the proper operation
of the camera. In reality, however, this is a very cumbersome task.
Moreover, even when the camera appears to be normally operating,
malfunctions are occurring. In general, it is difficult for the
operator to judge whether all the functions of the camera are
working properly.
SUMMARY OF THE INVENTION
[0013] Accordingly, the present invention is directed to an
electronic camera that substantially obviates one or more of the
problems due to limitations and disadvantages of the related
art.
[0014] An object of the present invention is to provide an
electronic camera that allows users easily and quickly to
understand the functions of the camera and makes advanced functions

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0045] Reference will now be made in detail to the preferred
embodiments of the present invention, examples of which are
illustrated in the accompanying drawings.
First Preferred Embodiment
[0046] FIG. 1 shows a block diagram illustrating operation of an
electronic camera according to a first preferred embodiment of the
present invention. The electronic camera according to the first
preferred embodiment includes an instruction input unit 1 (or
operation input unit), through which an instruction for the camera
operation is externally inputted, and an image pickup unit 2 for
capturing the image of an object in accordance with the instruction
received by the instruction input unit 1. The electronic camera
further has a recorder 3 for recording the image captured by the
image pickup unit 2 on a recording medium, a playback section 4 for
reproducing the image recorded on the recording medium in
accordance with the instruction received by the instruction input
unit 1, and a mode selector 5 for selecting operation modes
including an operation explanation mode (or operation or function
instruction mode). If the operation explanation mode is selected at
the mode selector, the playback section 4 displays the pre-stored
explanation of the camera operation that corresponds to the
instruction received by the instruction input unit 1.
[0047] FIG. 2 shows another example of the electronic camera
according to the first embodiment of the present invention. In this
electronic camera, data for explaining the camera operations are
pre-stored on a recording medium that is detachable from the main
body of the camera, and a mode selector 5 selects operational modes
including an operation explanation mode when the recording medium
is attached to the main body of the camera.
[0048] In the electronic camera of FIG. 1, when an instruction to
take pictures is input through the instruction input unit 1 by an
operator, the image pickup unit 2 starts capturing the images of an
object in accordance with the instruction ("image pickup
operation"), and recorder 3 records the image created by the image
pickup unit 2 on the recording medium.
[0049] The playback section 4 reproduces the image recorded on the
recording medium according to an display instruction ("display
operation"). The reproduction operation is performed when an
instruction to reproduce images is input through the instruction
input unit 1, for example.
[0050] When an operator selects an operation explanation mode
through the mode selector 5, the electronic camera enters the
operation explanation mode. In the operation explanation mode,
whenever a camera operation is carried out, an explanation of that
camera operation (referred to as "operation guide") is reproduced.
This operation guide may be in the form of an image and/or
sound.
[0051] In the electronic camera of FIG. 2, the operation guide is
pre-stored on a detachable recording medium. When the recording
medium is attached to the main body of the camera, the mode
selector 5 has an additional option to select the operation
explanation mode. The operation explanation mode may automatically
be selected based on whether the operation explanation guide is
recorded on the attached recording medium. Alternatively, the
operation explanation mode may be initiated by detecting attachment
of the recording medium, regardless of whether the operation
explanation mode is selected or not at the mode selector 5.
[0052] FIG. 3 shows a structural block diagram of an example of the
present embodiment. FIG. 4 shows perspective views of the
electronic camera according to the present example. As shown in
FIG. 3, a main body 21 is accompanied by a camera part 22. In the
camera part 22, an imaging lens (or optical system) 23 is installed
and an image pickup device 24 is arranged to receive light
transmitted through the imaging lens 23. The image signal from the
image pickup device 24 is supplied to a main processor unit (MPU)
26 via an A/D converter 25.
[0053] The MPU 26 is connected to a magneto-optical recording
medium 28 via a data access section 27. This magneto-optical
recording medium 28 is disc-shaped, randomly accessible, and is
detachable from the main body 21, for example. In addition, the MPU
26 is connected to a liquid crystal display (LCD) panel 29 to
display the image data output through the MPU 26. The LCD panel 29
has a touch screen 30 mounted therein, and pressing operations
sensed by the touch screen 30 are supplied to the MPU 26 as
positional information indicating the corresponding position in the
screen. Furthermore, MPU 26 controls a lens driving section 31 and
an exposure control section 32.
[0054] Various operation buttons 33 for selecting camera operations
are connected to MPU 26. As shown in FIG. 4, the operation buttons
33 include an image pickup button 34, focus button 35, zoom button
36, exposure button 37, and a mode selection button 38. In
addition, an auxiliary output terminal 40 and a magneto-optical
drive 41 (MO drive) are arranged at the side of the camera.
[0055] The MPU 26 performs various functions including processing
image data from the A/D converter 25 and the magneto-optical
recording medium 28, and controlling the data access section 27,
lens driving section 31, and the exposure control section 32. The
functions of the MPU further include recognizing instructions (or
operations) that are input through the touch screen 30 and
operation button 33, creating the image to be displayed on LCD
panel 29, and performing functions designated by the mode selection
button 38 when the magneto-optical medium having images for
explaining camera operations (referred to as "operation instruction
image," corresponding to "operation guide" above) is inserted.
[0056] The correspondence between the electronic cameras described
with reference to FIGS. 1 and 2 and the present example of FIGS. 3
and 4 is as follows. The operation recognition function of MPU 26,
touch screen 30, and the operation buttons 33 collectively
correspond to the instruction input unit 1. The imaging lens 23,
image pickup device 24, A/D converter 25, and the signal processing
function and control function of MPU 26 collectively correspond to
the image pickup unit 2. The control function of MPU 26 and data
access section 27 together correspond to the recorder 3. The
control function and the image-creation function of MPU 26 and data
access section 27 collectively correspond to the playback section
4. The mode selection function of MPU 26 and mode selection button
38 correspond to the mode selector 5.
[0057] Operation of the present embodiment is described with
reference to FIGS. 3 to 7B. First, the "Normal Mode" is described.
When the normal mode is selected by mode selection button 38, MPU
26 enters the normal mode and accordingly the camera is set to the
normal mode. In the normal mode, an initial screen shown in FIG. 5
is displayed on LCD panel 29. On the bottom portion of the screen,
operation buttons for image playback are displayed. They are, from
left to right, fast-reverse button 42, fast-forward button 43,
frame-reverse button 44, pause button 45, frame-advance button 46,
reverse-play button 47, stop button 48, and play button 49. The
operations of these buttons are performed through touch screen 30.
This type of user interface is well-known as a graphical user
interface (GUI). That is, operation buttons are displayed on LCD
panel 29 as objects, and MPU 26 responds to operator's touching (or
pressing) activities of these objects and reads out corresponding
image data and displays them on the LCD panel.
[0058] In the normal mode, normal actions are carried out by the
operations of operation buttons 33 and the operation buttons that
are displayed on the screen for image playback. For example, when
image pickup button 34 is pressed, image pickup device 24 performs
the photo-electric conversion of the image of the object obtained
through imaging lens 23, and as a result, the photo-electric signal
is converted to a digital signal through A/D converter 25. In
addition, at MPU 26, image processing operations, such as gamma
correction, outline enhancement, and white balance adjustments, are
conducted and the resultant data are compressed and encoded. The
encoded image data are recorded in an image file on the
magneto-optical recording medium 28 via data access section 27
(FIG. 7A).
[0059] When focus button 35, zoom button 36, and exposure button 37
are operated, MPU 26 recognizes their operations and accordingly
controls the lens driving section 31 and exposure control section
32 to conduct focus adjustment, zoom control, and exposure
adjustment, respectively.
[0060] In addition, when an operation button for image playback is
operated, MPU 26 reads out images from magneto-optical recording
medium 28 and plays them back. For example, when fast forward
button 43 is pressed, MPU 26 creates display images in which some
of the frames are dropped and displays them on LCD panel 29.
[0061] Next, the "Operation Instruction Mode" is explained. Suppose
a magneto-optical recording medium 28 has the operation instruction
images stored thereon for explaining the operations of operation
buttons 33 and the operations of operation buttons for image
playback. The information that indicates whether the operation
instruction images are stored or not in the disc is recorded in the
system region of magneto-optical recording medium 28 as a
characteristic attribute of the disc. If the disc contains the
operation instruction images, they are stored as separate image
files for each operation button. Identification data that uses the
name of each operation button as its identification name is stored
in the file label of each image file.
[0062] When this magneto-optical recording medium 28 is attached at
MO drive 41, MPU 26 accesses the system region and detects whether
operation instruction images exist using the characteristic
attribute of the disc. When operation instruction images exist, MPU
26 selects the operation instruction mode and the camera is
automatically set to an operation instruction mode.
[0063] In a read only memory (ROM) inside MPU 26, a sequence
program for operation instruction mode is stored. This program is
read out and MPU 26 conducts the appropriate actions, as
follows.
[0064] During the operation instruction mode, assume that image
pickup button 34 is pressed, for example. MPU 26 recognizes the
operation (See FIG. 6, Step 1 (S1)) and accesses the file label
that has "image pickup button" as its identification name via data
access section 27.
[0065] In the file label, the relative address indicating the
location of operation instruction image data for the image pickup
button is stored. This address is used to seek the image data.
[0066] When the operation instruction image of image pickup button
34 is found, MPU 26 reads out these image data, decodes, and
displays them on LCD panel 29 (FIG. 6, Steps 2 and 3 (S2, S3)), as
shown in FIG. 7B.
[0067] The contents of the operation instruction images are, for
example, a visual image explanation of how to press the operation
button and/or what kind of function will be carried out when the
operation button is pressed.
[0068] Similarly, when other buttons: focus button 35, zoom button
36, exposure button 37, and the operation button for image
playback, are pressed, operation instruction images that explain
the corresponding button operation and/or function in the normal
mode are played back.
[0069] Switching to the operation explanation mode may also be
carried out by the mode selection operation of mode selection
button 38. Further, it is possible to record photographic images in
the remaining empty spaces of magneto-optical recording medium 28
in which operation instruction images are stored.
[0070] As described above, according to the electronic camera of
the present embodiment, the operation instruction image about each
operation button can be played back just by pressing an operation
button. Therefore, without depending on the operation manual, even
users with poor understanding of the camera operations can
understand the camera operations and functions within a short
period of time and can start using the camera efficiently.
[0071] In this embodiment, the operation instruction images of the
present embodiment are moving images. However, they are not limited
to moving images and it is possible to display texts for the
operation instructions, for example. Alternatively, it is possible
to give operation instructions through sound by storing sound data
in magneto-optical recording medium 28.
[0072] Also, the recording medium is not limited to a
magneto-optical recording medium. A magnetic recording medium
(which is not limited to a disc form and includes a tape form,
etc.), an optical recording medium, or a semiconductor recording
medium (memory card, etc.) can be used as well.
[0073] Furthermore, it is possible to play back the operation
instruction images for the operations of the image adjustment
buttons, such as brightness adjustment button 50 and white balance
adjustment button 51, as shown in FIG. 8. During display of such
information, it is possible to display a sample image and actually
adjust the quality of the sample image in correspondence to the
operation of the image adjustment buttons. By doing this, the
operator can learn the operation of the image adjustment as she
experiences it.
[0074] Auxiliary output terminal 40 is a terminal for outputting
images to other devices, such as personal computers. Using the
auxiliary terminal 40, it is possible, for example, to play back
operation instructions images on an external terminal or
display.
[0075] In the present embodiment, one set of operation instruction
images are used for each instruction. However, the invention is not
limited to this. It is possible to have an operation instruction
mode that stores multiple sets of operation instruction images (for
example, instruction through moving images, instruction through
texts, instruction through sound, instruction in English, Japanese,
or other languages) on the recording medium so that the operator
can select desirable ones from them. Also, if sequence programs of
the operation instruction mode are stored on the same recording
medium as the operation instruction image, the operation
instruction images and the sequence programs of the operation
instruction mode can be changed at the same time.
[0076] Moreover, in this embodiment, the operation instruction
images may be stored on detachable magneto-optical recording medium
28. However, the invention is not limited to this and it is
possible to store the operation instruction images in an internal
memory of the camera main body, for example.
[0077] In this embodiment, MPU 26 may automatically select the
operation instruction mode when magneto-optical recording medium 28
having operation instruction images is attached. However, the
invention is not limited to this and it is possible to design the
camera so that if there is no operation instruction image stored in
a disc, then the camera cannot be switched to the operation
instruction mode. Furthermore, it is possible to not only
automatically select the operation explanation mode but also
automatically playback the operation instruction images explaining
overall operations and/or functions of the electronic camera. For
example, general instructions for the camera functions or
instructions about the photographic process are appropriate as the
content of the operation instruction images.
[0078] The electronic camera of FIG. 1 has an operation instruction
mode in which when a camera operation is carried out, an operation
instruction guide for that operation is played back. Therefore, the
operator can understand the function of the camera efficiently and
quickly without relying on the operation manual. In addition, even
if the camera operation is complicated, users can learn the
operation easily.
[0079] In addition, it is possible to even omit operation manuals,
therefore eliminating the costs for operation manual
production.
[0080] When a recording medium, on which guide images are stored,
is attached, the electronic camera of FIG. 2 is automatically
switched to an operation instruction mode. Therefore, it is
possible to avoid mistakes or troubles in switching to the
operation instruction mode.
[0081] As described above, the electronic camera of the present
embodiment can be easily used by operators who are inexperienced
with camera operations.
Second Preferred Embodiment
[0082] FIG. 9 shows a principle block diagram of an electronic
camera according to a second preferred embodiment of the present
invention.
[0083] The electronic camera of FIG. 9 has an image pickup unit 101
that captures the image of an object, and a recorder 102 that
records the image generated by the image pickup unit 101 on a
recording medium. Playback section 103 plays back the image that is
recorded on the recording medium. Mode selector 104 can select a
function diagnosis mode by an external selection operation.
Function tester 105 tests each function of the camera when the
function diagnosis mode is selected by mode selector 104.
[0084] FIG. 10 shows a principle block diagram of another example
of the electronic camera according to the second preferred
embodiment of the present invention. In the electronic camera of
FIG. 10, an image pickup function of the image pickup unit 101 is
selected in accordance with an external operation designating that
function. The image pickup unit 101 captures images according to
the selected function. When one of the image pickup functions at
the image pickup unit 101 is selected while the camera is in the
function diagnosis mode set by the mode selector 104, the function
tester 105 tests the corresponding image pickup function.
[0085] FIG. 11 shows a principle block diagram of still another
example of the electronic camera according to the second preferred
embodiment of the present invention. In the electronic camera of
FIG. 11, a playback function to be performed at the playback
section 103 is selected by external operations, and the playback
section 103 plays back images (which is recorded on the recording
medium, for example) in accordance with the selected playback
function. When one of the playback functions to be performed at the
playback section 103 is selected through an external operation
while the camera is in the function diagnosis mode, function tester
105 tests the corresponding playback function.
[0086] FIG. 12 shows a principle block diagram of still another
example of the electronic camera according to the second embodiment
of the present invention. In the electronic camera of FIG. 12, the
function tester 105 displays the test results on a display screen
that is also used for displaying images through the playback
section 3
[0087] In the electronic camera of FIG. 9, the image pickup unit
101 takes a picture of an object and creates an image. The recorder
102 records the image created by image pickup unit 101 on a
recording medium. Playback section 103 plays back the image
recorded on the recording medium. When an operator selects the
function diagnosis mode through the mode selector 104, the
electronic camera is set to the function diagnosis mode. Then,
function tester 105 automatically carries out predetermined
function (performance) tests for each function of the camera.
[0088] According to the electronic camera of FIG. 10, an image
pickup function can be selected through external operations by an
operator, and the image pickup unit 101 captures images in
accordance with the selected image pickup function. When one of the
image pickup functions is selected while the camera is set to the
function diagnosis mode, function tester 105 performs predetermined
tests with respect to the corresponding image pickup function.
Therefore, with the electronic camera of FIG. 10, the function of
the camera that is designated by the operator is selectively
tested.
[0089] With the electronic camera described in FIG. 11, a playback
function is selected by an external operation, and playback section
103 plays back images in a condition corresponding to the selected
playback function (normal play, fast forward, etc.).
[0090] When the camera is in the function diagnosis mode and a
playback function is designated, function tester 105 performs
predetermined tests for the playback function. Therefore, the
electronic camera of FIG. 11 selectively tests the playback
function that is designated by the operator.
[0091] With the electronic camera described in FIG. 12, function
tester 105 performs predetermined tests for all or a certain group
of functions of the camera, and displays the test results (whether
each function of the camera is normal, for example) on the display
screen (a screen also used for playback section 103 to play back
and/or display the image).
[0092] FIG. 13 is a structural block diagram of the electronic
camera according to the present embodiment. FIG. 14 is a
perspective view of the electronic camera of FIG. 13.
[0093] Referring to FIG. 13, main body 121 is attached to a camera
part 122. Imaging lens 123 (or optical system) is installed in the
camera part 122, and an image pickup device 124 is arranged to
detect light transmitted through the imaging lens 123. The image
signal from image pickup device 124 is input into MPU 126 via A/D
converter 125.
[0094] MPU 126 is connected to magneto-optical recording medium 128
via data access section 127. The magneto-optical recording medium
128 has a disc-shape or the like, for example, and may be
detachable from main body 121. Also, it is possible to conduct
random access on the recording medium 128.
[0095] Image signals output from MPU 126 are supplied to an LCD
panel 129. The LCD panel 129 has a touch screen 130 mounted
thereon, and a pressing operation sensed by touch screen 130 is
supplied to MPU 126 as positional information indicating the
corresponding position in the screen. The control signals output
from MPU 126 are supplied to lens driving section 131 and exposure
control section 132.
[0096] Various operation buttons 133 are installed in the main body
121 and connected to MPU 126. Examples of operation buttons are
shown in FIG. 14. From right to left, an image pickup button 134,
focus button 135, zoom button 136, exposure button 137, and a mode
selection button 138 are installed at the top plate of main body
121. In addition, an auxiliary output terminal 140 and an MO drive
141 are installed at the side panel of the camera.
[0097] MPU 126 has an image signal processing function for
processing the image signals from A/D converter 125 and the image
signals read out from magneto-optical recording medium 128, and a
control function for controlling data access section 127, lens
driving section 131, and exposure control section 132. MPU 126
further has an instruction (operation) recognition function that
recognizes the instructions (operations) that are input through
touch screen 130 and operation buttons 133, an image creation
function that creates the image that is displayed on LCD panel 129,
a mode selection function that conducts mode selection designated
by mode selection button 138, and the diagnostic function that
conducts the diagnosis of each function of the camera.
[0098] The correspondence between the electronic camera of FIG. 9
and the present example is as follows. Image pickup section 101
corresponds to imaging lens 123, image pickup device 124, A/D
converter 125, and the signal processing function of MPU 126.
Recorder 102 corresponds to the control function of MPU 126 and
data access section 127. Playback section 103 corresponds to the
signal processing function, controlling function, and image
creation function of MPU 126 and data access section 127. Mode
selector 104 corresponds to the operation recognition function and
mode selection function of MPU 126. Function tester 105 corresponds
to the signal processing function, controlling function, and the
diagnostic function of MPU 126.
[0099] In addition to the correspondence described above, in the
electronic camera of FIG. 10, the image pickup device 101 in FIG.
10 corresponds to the controlling function and the
operation-recognition function of MPU 126.
[0100] In the electronic camera of FIG. 11, in addition to the
correspondence described above, playback section 103 corresponds to
the operation-recognition function of MPU 126.
[0101] In the electronic camera of FIG. 12, in addition to the
correspondence described above, function tester 105 corresponds to
the image creation function of MPU 126.
[0102] Operation of the present embodiment is described with
reference to FIGS. 13 to 16B as follows. First, the "Normal Mode"
is described. An electronic camera according to the present
embodiment can be switched to a "Normal Mode" similar to that for
the above-mentioned first preferred embodiment by operating the
mode selection button 138. In the normal mode, the initial screen
similar to that of FIG. 5 is displayed on LCD panel 129, for
example. As shown in FIG. 5, a plurality of operation buttons for
image playback are displayed on the bottom portion of the
screen.
[0103] In addition, the electronic camera of the present embodiment
may be equipped with a button for reading out an image quality
adjustment screen (the button is not shown in the figure). When the
button is pressed, the image quality adjustment screen (the one
shown in FIG. 8, for example) is displayed on LCD panel 129.
[0104] These operation buttons can be operated through touch screen
130 utilizing a known technology, such as a GUI (Graphical User
Interface). That is, on LCD panel 129, operation buttons are
displayed as objects, and MPU 126 senses operator's touching
activities of these objects and accordingly plays back and adjusts
the image.
[0105] In the normal mode, normal actions are carried out by the
operation of operation buttons 133 and the operation buttons for
image playback, 42 to 49 of FIG. 5, and image quality adjustment
buttons 50 and 51 of FIG. 8.
[0106] For example, when image pickup button 134 is pressed, image
pickup device 124 performs a photo-electric conversion of the image
of an object obtained through the imaging lens 123, and accordingly
the photo-electric signal is converted into a digital signal
through A/D converter 125. In addition, at MPU 126, image
processing, such as gamma correction, outline enhancement, and
white balance adjustments, is conducted and the resultant data are
then compressed and encoded. The encoded image data are recorded in
an image file on magneto-optical recording medium 128 via data
access section 127 (FIG. 16A).
[0107] When focus button 135, zoom button 136, or exposure button
137 is operated, MPU 126 recognizes that operation and controls
lens driving section 131 and exposure control section 132 to
conducts focus adjustment, zoom control, or exposure adjustment,
respectively.
[0108] In addition, when the operation buttons 42 to 49 (FIG. 5)
for image playback are operated, MPU 126 reads out images
corresponding to the selected operation from magneto-optical
recording medium 128 and plays them back. For example, when fast
forward button 43 (FIG. 5) is pressed, MPU 126 creates moving
display images in which some of the frames are dropped, and
displays them on LCD panel 129.
[0109] Furthermore, when brightness adjustment button 50 or white
balance adjustment button 51 (FIG. 8) are pressed, MPU 126 conducts
gain control of the photographic image, brightness control of the
playback image, and the color signal control, etc., in accordance
with the selected operation.
[0110] Next, the "Function Diagnosis Mode" is explained. When the
electronic camera of the present embodiment is switched to the
function diagnosis mode by mode selection button 138, the camera is
set to the function diagnosis mode. In this mode, predetermined
tests are carried out for each function of the camera corresponding
to the respective operation button. This test may be carried out
with a sequence program stored in the internal ROM of MPU 126.
[0111] For example, when the image pickup button 134 is pressed,
MPU 126 recognizes that action and reads out a sequence program for
testing the corresponding image pickup function (FIG. 15, Step S1).
MPU 126 accordingly carries out the following tests for the image
pickup function.
[0112] First, the image of an arbitrary object is captured through
the imaging lens 123 for a predetermined period of time. Then, the
image is compressed and encoded to generate image data (FIG. 15,
Steps S2 and S3). The image data is recorded in a blank region of
magneto-optical recording medium 128 as a test image file (FIG. 15,
Steps S4 and S5). When the test image file is recorded on
magneto-optical recording medium 128 and the test of the function
is completed without abnormality, MPU 126 creates a message "The
image pickup function is normal." and displays it on LCD panel 129
(FIG. 15, Step S6), as shown in FIG. 16B. Finally, MPU 126 accesses
the file label of the test image file via data access section 127
and deletes the test image file by rewriting the file attribute to
an overwritable attribute (FIG. 15, Step S7).
[0113] If there is abnormality in the image pickup function, e.g.,
the subject images are not converted to the image data or the test
image file is not recorded properly, MPU 126 displays a message
"There is a problem with the image-pickup function" (FIG. 15, Step
S8) and aborts the test.
[0114] When zoom button 136 is pressed, MPU 126 recognizes that
action and tests the zooming function with a sequence program. MPU
126 drives imaging lens 123 from the maximum telephoto view to the
maximum wide-angle view via lens driving section 131, for example.
The design lens positions of the lens at the maximum telephoto view
and maximum wide-angle view and the design duration of the zooming
from the maximum telephoto view to the maximum wide-angle view are
pre-stored in the internal ROM of MPU 126. By comparing and
analyzing the stored design data with the actual lens positions and
actual zoom duration that are measured by a zoom encoder, whether
the zooming action was carried out properly can be determined. If
the zooming action is conducted properly, MPU 126 displays a
message "The zoom function is normal" on LCD panel 129.
[0115] If there are some problems during the zooming test action:
e.g., the lens is not driven from the maximum telephoto view to the
maximum wide-angle view, or the zooming speed is slow, a message
"There is a problem with the zoom function" is displayed on LCD
panel 129 and the testing action is aborted.
[0116] Moreover, when playback button 49 (FIG. 5) is pressed, MPU
126 recognizes the operation and the playback function is tested
with a sequence program for testing the playback function. In the
blank region on magneto-optical recording medium 128, sample image
files are pre-stored. MPU 126 accesses the file label and searches
for the sample image file via data access section 127. Then, MPU
126 reads out the sample image data via data access section 127,
creates a display image, and displays it on LCD panel 129. When all
the sample image data are read out and the playback action is
completed without abnormality, MPU 126 displays a message "The
playback function is normal" on LCD panel 129.
[0117] If there is abnormality during the test of the zooming
action: e.g., the improper readout function of the image data or
incomplete creation of the display image, then a message "There is
a problem with the playback function" is displayed on LCD panel 129
and the test action is aborted.
[0118] Furthermore, when brightness adjustment button 50 (FIG. 8)
is pressed, MPU 126 recognizes the operation, and with the sequence
program, the following diagnosis is carried out.
[0119] In the blank region of the magneto-optical recording medium
128, sample image files are pre-stored. MPU 126 reads out the
sample image data and displays it on LCD panel 129. Then, MPU 126
conducts gain control of the brightness within the range from 0 to
15 dB and creates images in which the brightness of the sample
images are varied sequentially. Subsequently, LCD panel 129
displays the thus created sample images having brightness changed
sequentially. When the test is completed without abnormality, MPU
126 displays a message "The brightness adjustment function is
normal" on LCD panel 129.
[0120] When there are some problems with the gain control: e.g.,
the brightness fails to change by the predetermined design amount,
a message "There is a problem with the brightness adjustment
function" is displayed and the test is aborted.
[0121] As described above, according to the electronic camera of
the present embodiment, various camera functions can be tested
simply by pressing the respective operation buttons under the
function diagnosis mode and each testing operation is automatic.
Therefore, the operator can promptly confirm camera functions and
can prepare for shooting pictures at ease.
[0122] The electronic camera according to the present invention
also can be adapted to automatically test all the camera functions
once the camera is switched to the function diagnosis mode by mode
selection button 138. In this case, the results of the test may be
used to determine the various statuses of the camera, the messages,
such as "All the functions are normal," "There is some problem with
the machine, however, you can take pictures," or "You cannot take
pictures" may be displayed on the screen.
[0123] Also, the electronic camera according to the present
invention can indicate not only whether the camera functions are
normal, but also where the problem exists inside the camera.
[0124] In the present embodiment, messages indicating whether the
camera is functioning normally are displayed on LCD panel 129.
Alternatively, the results of the diagnosis may be output in the
form of sound.
[0125] The recording medium above is not limited to the
magneto-optical recording medium. It is possible to use a magnetic
recording medium (which is not limited to a disc shape and includes
a tape form, etc.), optical recording medium, or semiconductor
recording medium (e.g., memory card).
[0126] The electronic camera described with reference to FIG. 9 can
automatically test each function of the camera when the function
diagnosis mode is selected. Therefore, the operator can, in
advance, confirm whether the camera is working normally or not.
Accordingly, the operator can prepare for shooting pictures at
ease.
[0127] The electronic camera described with reference to FIG. 10
can test the image pickup function of the camera that is designated
through an external operation. Therefore, the operator can easily
and accurately determine whether the photographic function is
normal.
[0128] The electronic camera described with reference to FIG. 11
can test the playback function of the camera that is designated by
an external operation. Therefore, the operator can easily and
