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.

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.
