Electronic sighting device and method of calibratingreticule
without adjusting optical lens position
Abstract
An electronic sighting device and method is described for
calibrating a shooting device. The sighting device includes a
display screen, mounting clip, optical lens, and an external
infra-red torch for light compensation. By one discharge from the
shooting device, the adjustable targeting reticule of the
electronic sighting device can be set to align with the targeting
position. The alignment process does not require adjusting the
optical lens position, nor the mounting position of the sighting
device.

Claims
1. A sighting device comprising, a camera device mounted on a
shooting device to show a field of view on the screen of the
device. A targeting reticule will be generated and displayed on the
screen to indicate the aiming position, and this targeting reticule
can be adjusted by aligning with, the position in a field of view
on screen, or the position in the recorded video, of the previous
discharge, through the functional keys on the camera manually.
2. The sighting device according to claim 1, wherein the device's
screen shows the current field of view with the targeting
reticule.
3. The sighting device according to claim 1, wherein the sighting
device records video and playback on the screen for aligning of the
targeting reticule.
4. The sighting device according to claim 1, wherein the sighting
device embedded with a USB socket for computer communication and
video transfer from the sighting device.
5. The sighting device according to claim 1, wherein the sighting
device embedded with a TF memory card slot for storage of the
recorded video.
6. The sighting device according to claim 1, wherein the sighting
device includes optical lens with an adjustable focal length to
match a distance at which the target is expected to be struck.
7. A sighting device comprising with an aluminum body with a
mounting clip for mounting on a shooting device.
8. A sighting device comprising with an external mounting infra-red
torch for the light compensation for camera view and video
recording.
9. The calibrating method according to claim 1, wherein the
calibration requires one discharge from a shooting device to strike
on target, and moves the targeting reticule on the screen to the
struck position. For implementing the movement of the targeting
reticule can be done by two operations, either (1) to keep the same
screen display of the field of view, and move the targeting
reticule to the correct position. The targeting reticule may not
still locate in the center of the screen; or (2) to keep the
targeting reticule in the center of the screen and shift the
viewing area by the deviated distance. Both methods can be
completed through the camera functional keys.
Description
FIELD OF THE INVENTION
[0001] This invention is relates to the method used in an
electronic sighting device with a sighting screen for the field of
view, particularly, the view image is digital processed for
displaying and calibrating the targeting reticule.
BACKGROUND OF THE INVENTION
[0002] A traditional sighting device for a shooting device is made
by an optical lens. For targeting, user requires to see through a
small eye piece, which image is small and will cause the eye tire
after a long time usage. Moreover, an optical sighting device is
not work in a very low-lux environment. Another drawback is the
calibration of an optical sighting device requires numbers of
discharge from shooting device, the number of times will depend on
the user experience for different kinds of surrounding
environment.
[0003] This invention of electronic sighting device, overcomes the
problems of the optical sighting device. The calibration of this
electronic device can be carried out in a straight and simple
method.
DESCRIPTION
[0004] This invention adapted the current electronic camera
technology to build for a night vision sighting device for shooting
devices. It displays the field of shooting view on screen, records
and playbacks the discharges. The recorded video clips can be
transferred to a USB device or store in a TF memory card.
[0005] The device is composed by an aluminum body, LCD screen,
optical lens and cover, mounting clips, battery compartment and an
external infra-red torch.
[0006] The optical lens is embedded into the aluminum body and its
focal length can be adjusted to match with different distance of
shooting view. When the view image goes through the lens and
reaches the optical sensor of the camera, it will be displayed on
the LCD screen by adapting the electronic camera technology. User
can select to see the almost real time image from the screen or
records as a video data. For the aiming purpose, a targeting
reticule is added on the view image through digital image
processing and controlled by the software of camera.
[0007] The LCD screen is located at the back of the aluminum body.
A large screen is easy for viewing and aiming.
[0008] It is a battery operated device and its battery compartment
is located on the right-hand-side of the aluminum body.
[0009] In a low-lux environment, an external infra-red torch
provides light compensation for the view, which is mounted on the
left-hand-side of the aluminum body.
[0010] A mounting clip is located at the bottom of the aluminum
body and used to mount the sighting device on a shooting device
body.
[0011] Calibration procedure for displaying targeting reticule
Step 1
[0012] Mount an electronic sighting device on the shooting device's
body.
Step 2
[0013] Turn on the sighting device and see the view on the LCD
screen. The targeting reticule is shown in the center of the
screen.
Step 3
[0014] Adjust the optical lens to match with the shooting distance
in order the LCD screen shows a suitable view of the strike
target.
Step 4
[0015] Discharge the first shoot to target.
[0016] Method 1, move the targeting reticule to the struck position
of the first discharge.
[0017] Method 2, move the viewing area away from the center of the
screen until the targeting reticule hit on the position of the
first discharge.
Step 5
[0018] Save the position and finished the calibration.
