Description
FIELD OF THE INVENTION
[0001] This invention relates to an image information recording
method, particularly relates to an image information recording
method using a silver halide photographic light-sensitive material,
hereinafter occasionally referred to a light-sensitive
material.
[0002] Recently, it is frequently performed to take image
information into a personal computer and to utilize the image
information after processing by the computer, accompanied with
popularization of the personal computer and interment system. A
method by photographing using a digital camera is applicable for
taking the image information into the personal computer. However,
the quality of an image taken by the digital camera is considerably
insufficient since the number of pixel of the digital camera is
several hundred thousands and about a million at the highest.
[0003] On the other hand, a high quality image data with about a
ten million pixel can be obtained by reading the image information
formed on an usual color photographic light-sensitive material by a
scanner even if a single use camera is used. Such the method is
also advantageous in that the image information the usual
photographic light-sensitive material accumulated for many years.
However, in such the method, a problem is raised that a long time
is necessary to obtain the image information since two steps of
procedure, processing a color light-sensitive material in a
photo-shop and reading the image information into a recording
medium, are necessary.
[0004] Although prior art is described in Japanese Patent
Publication Open for Public Inspection (JP O.P.I.) Nos. 9-121265,
9-230557 and 9-281675, and U.S. Pat. No. 5,627,016, such the
techniques are insufficient in the image quality and the
rapidness.
[0005] In JP O.P.I. No. 9-146247, a technique for obtaining image
information, in which the light-sensitive material is developed,
without bleaching and fixing, and the image formed is read by a
scanner to obtain the image information. However, in the method
described in this publication, it is considerably difficult to
obtain the image information by reading the image by the scanner
since the transmission density of the light-sensitive material is
considerably increased by the presence of developed silver and
silver halide remained in the light-sensitive material after
processing.
[0006] As prior art in which image information is read before
drying process, a photographic system is described in JP O.P.I. No.
5-100321 in which a negative film is scanned after color developing
and before drying to obtain image data. However, the processing
disclosed in the publication includes the steps of color
developing, bleaching, bleach-fixing and washing, and the scanning
is performed during the washing step. Therefore, the method is
insufficient in the simpleness and the rapidness of the procedure
since the four steps of processing are carried out.
[0007] U.S. Pat. No. 5,101,286 discloses a method in which image
data are read by an image processor from a negative film after
color developing and before bleaching thereof. In the method, the
reading is performed after bleaching and before fixing of the
light-sensitive material, Accordingly, the level of image quality
is insufficient since increasing in the transmission density and an
unevenness of image caused by remained silver halide are
formed.
SUMMARY OF THE INVENTION
[0008] The first object of the invention is to provide an image
information recording method by which high quality image
information can be obtained simply and rapidly by the use of an
usual silver halide color photographic light-sensitive
material.
[0009] The second object of the invention is to provide an image
information recording method by which a high quality image
inhibited in the formation of unevenness can be obtained.
[0010] The objects of the invention can be attained by an image
information recording method comprising the steps of
[0011] imagewise exposed to light a silver halide photographic
light-sensitive material comprising a support having thereon a
light-sensitive layer comprising light-sensitive silver halide and
a coupler,
[0012] color developing the image wise exposed silver halide
photographic light-sensitive material,
[0013] converting the image information formed on the silver halide
photographic light-sensitive material to electric information while
the light-sensitive material is wetted without a drying and at
least a part of developed silver is remained in the light-sensitive
material, and
[0014] recording the image information on another recording medium
according as the electric image information.
DETAILED DESCRIPTION OF THE INVENTION
[0015] In the technique disclosed in U.S. Pat. No. 5,101,286, a
negative film is color developed and bleaching and image data are
read by a image processor. In the light-sensitive material to be
read, developed silver has removed and silver halide has been
remained since the reading is carried out after bleaching and
before fixing.
[0016] According to studying by the inventors, an unevenness of
image caused by silver halide is formed when the light-sensitive
material in which silver halide is remained is read, and the level
of quality of thus obtained image is insufficient.
[0017] It is found by the inventors that the unevenness of image
can be prevented when the light-sensitive material is read out by a
scanner after the color developing while at least a part of
developed silver is remained in the light-sensitive material. It is
a surprising fact. It is preferable that the light-sensitive
material is scanned without any bleaching process. The bleaching
process is a process for oxidizing developed silver remained in a
light-sensitive material to silver halide. Moreover, in the case of
a part of developed silver is remained in the light-sensitive
material at the time of canning, it is found that a better image
quality, particularly in graininess, can be obtained when the image
is read by a scanner while the light-sensitive material is in a
wetted state.
[0018] In the invention, although the silver halide may be remained
without removing, it is preferable to be removed by 50% or more,
and further preferably to be removed by 90% or more. The silver
halide can be removed by a fixing or bleach fixing process.
[0019] In the invention, the drying process is a process for
removing moisture from the processed light-sensitive material. The
method for drying includes that by a heating roller or by hot
air.
[0020] The light-sensitive material in a wetted state is a
light-sensitive material containing water or a processing solution
in a weight ratio of from 0.1 to 1 of times, preferably 1 time, of
the weight of the water or processing solution to be contained in
all layers of the light-sensitive material in a state of maximally
swelled.
[0021] There is no limitation on the kind of silver halide color
photographic light-sensitive material to be used in the invention.
A color negative film, a color reversal film and a direct positive
light-sensitive material are also usable.
[0022] The silver halide color photographic material of the
invention preferably has a red-sensitive silver halide emulsion
layer, a green-sensitive silver halide emulsion layer and a
blue-sensitive silver halide emulsion layer each capable of
recording red-light, green-light and blue-light, respectively.
[0023] The silver halide color photographic material to be used in
the invention preferably has a speed of not less than ISO 30, more
preferably not less than ISO 100, further preferably not less than
400.
[0024] It is a presupposition of the invention that the image
information on the developed light-sensitive material is read out
by a scanner and the image is processed by a personal computer.
However, image information obtained by an usual Processing C-41
with a color developing time of 195 seconds is a processing
optimized for outputting an image for an optical printer, and not
for obtaining image information suitable for the image
processing.
[0025] In the reading out by the scanner, a lowered fog and lowered
gamma are preferable for reducing the load of scanning.
[0026] It has been found by the inventors that image information
with a low fog and a low gamma suitable for reading out by the
scanner can be obtained by reducing the developing time to shorter
than usual time of 195 seconds.
[0027] In the invention the color developing time is preferably not
more than 180 seconds, more preferably 140 seconds.
[0028] In the invention, a developing solution containing a
p-phenylenediamine color developing agent may be used.
[0029] The temperature of the color developing solution is
preferably not less than 40.degree. C., more preferably not less
than 40.degree. C.
[0030] The concentration of the color developing agent is
preferably not less than 0.016 moles per liter, more preferably
0.030 moles per liter.
[0031] The pH of the color developing solution is preferably not
less than 10.0, more preferably not less than 10.4.
[0032] A know method, system and condition including those anther
than the above-mentioned can be applied in the invention without
any limitation. The light-sensitive material can be developed by
jetting, such as an ink-jet development or coating the developing
solution in an amount capable of substantially being permeated into
the light-sensitive material. There is no limitation on the method
for jetting the developing solution. The developing agent may be
jetted through a single movable nozzle or through plural fixed
nozzles. The developing solution may be jetted through a moving
nozzle onto the fixed light-sensitive material or through a fixed
nozzle on to the moving light-sensitive material. A combination of
such the procedures may also be usable.
[0033] When the development is carried out by supplying the
developing solution in an amount of capable of being permeated into
the light-sensitive material, there is no limitation on the medium
conveying the developing solution, and a felt, clothes, and a metal
having a slit or hole are preferably usable. A method in which the
developing solution is coated on the light-sensitive material by a
medium while jetting the developing solution onto the
light-sensitive material or the medium.
[0034] In the invention, the image information formed on the
light-sensitive material is read out by a scanner (a CCD is also
may usable) to convert to electric information while the
light-sensitive material is in the wetted state.
[0035] In the invention, the scanner is a device to convert the
reflection or transmission optical density of the light-sensitive
material read out by scanning to image information. It is usual to
move the optical head of the scanner in the direction different
from the moving direction of the light-sensitive material to scan
the necessary area of the light-sensitive material. Although such
the method is recommendable, it may be allowed to move only the
optical head of the scanner while the light-sensitive material is
fixed, or to move only the light-sensitive material while the
optical head of the scanner is fixed. These procedures may be
applied in combination.
[0036] A tungsten lamp, a fluorescent lamp, a light emission diode,
or a laser may be used as the light source for reading out the
image information without any limitation. The tungsten lamp is
preferably used in the reason of a low cost and laser, a coherent
light source, is preferable since which has a high stability, a
high brightness and hardly influenced by scattering. Although there
is no limitation on the reading out method, it is preferred to read
out by transmission light from the viewpoint of the sharpness of
image.
[0037] It is preferable that the light-sensitive material contains
a color developing agent. The color developing agent to be
contained in the light-sensitive material may be a p-phenylene
diamine compound or a p-aminophenol compound. Among such the

[0130] Moreover, the removed ratio of silver halide and remained
ration of developed silver in the processed samples were
determined. Results are listed in the following Table 3. The
remained amount of developed silver is described in the relative
value when the amount in sample 1 was set at 100.

[0131] In the comparative experiment 1, in which only the
developing process is applied, the image information is difficulty
obtained by reading by the scanner since the transmission density
is considerably lowered by the presence of remained developed
silver and silver halide, and a good image cannot be obtained even
when a suitable image processing is applied.
[0132] In the comparative experiment 2, the image is good. However,
the simpleness and rapidity of the processing is insufficient since
the four processes requiring 8 minutes and 20 seconds in total,
namely color development, bleaching, bleach-fixing and washing, are
necessary.
[0133] In the comparative experiment 3, the reading is carried out
after the bleaching process. Accordingly developed silver is
removed and silver halide is remained in the light-sensitive
material at the moment of reading-out. In such the case, although
the reading-out by the scanner is possible, the image quality is
insufficient since the transmission density is lowered and an
unevenness of the image density caused by remained silver halide is
formed.
[0134] In the experiments 4 through 7, in which the light-sensitive
material is read after color development without bleaching process,
the unevenness of the image caused by silver halide is dissolved. A
high quality image can be obtained when the developing time is
shortened to not more than 180 seconds since the load for
reading-out on the scanner is reduced. Furthermore, the processing
is considerably simplified and a rapidity of the processing is
realized since the drying process is omitted. In experiments 8 to
11 each including the drying process, a degradation in the
graininess of the image is observed compared to experiments 4 to 7,
additionally the prolongation of the processing time.
[0135] It is realized by the invention that a quality image having
no unevenness can be simply and rapidly obtained by reading-out
image information in a wetted state after color developing without
drying process while at least a part of developed silver is
remained.

[0162] The structures of the couplers used in Sample 2 are shown
below. 7
[0163] Thus prepared Sample 2 was slit and perforated in the format
of 35 mm negative film. The film was put in a camera and a human
and Macbeth Chart were photographed by the film. Then the film was
processed by means of the following activator solution under the
following conditions. The image information formed on the processed
film was read out by a film scanner Q-scan manufactured by Konica
Corp. The image information was processed by a personal computer
and printed out by a printer PM-700C manufactured by Epson Co. Ltd.
The printed image was visually evaluated and classified into four
ranks in the same manner as in Example 1. The results thus obtained
are shown in Table 4.

A (Inventive)
[0170] According to the invention, the processing can be
considerably simplified and the processing time can be shortened
since the drying process is omitted. Moreover a high quality image
and formation of unevenness of image and precipitation of salts on
the surface of the light-sensitive material caused by drying were
inhibited by reading out the image formation while the
light-sensitive material is wetted.
