Abstract: A method for adjusting the reticule includes the following steps: displaying a coordinate on the touch display screen, setting the origin of the coordinate at the center of the touch display screen, aiming at an object with the origin, firing the first bullet to get the first bullet hole on the touch display screen, obtaining the coordinate value of the first bullet hole, determining the opposite value, clicking on the place of the opposite value, moving the origin of the coordinate to the place of the opposite value, and aiming at the object with the new origin, firing the second bullet to get the second bullet hole, removing the coordinate; clicking the second bullet hole, an adjusted reticle appearing.

Abstract: A touch display screen used for adjusting and determining the reticle of an electronic firearm sight, includes: a display; a touch screen installed in front of the display; and a display driver. The touch display screen is connected with a processor, the processor in turn is connected with a memory; the memory is provided with pre-saved data of a Cartesian coordinate system, ballistic trajectory data of different bullets and reticle scales formed based on different ballistic trajectories of different bullets; the touch display screen receives operations of adjusting the reticle from a user and sends corresponding information to the processor; the processor analyzes the information through using the pre-saved data in the memory, forms commands, and sends the commands to the touch display screen to execute.

Abstract: An electronic firearm sight comprises a set of zoom lens, an image sensor, a processor, a memory, and a touch display screen for the operation of adjusting and determining a reticle. A method for adjusting the reticule comprises the following steps: displaying a coordinate on the touch display screen, setting the origin of the coordinate at the center of the touch display screen, aiming at an object with the origin, firing the first bullet to get the first bullet hole on the touch display screen, obtaining the coordinate value of the first bullet hole, determining the opposite valu, clicking on the place of the opposite value, moving the origin of the coordinate to the place of the opposite value, and aiming at the object with the new origin, firing the second bullet to get the second bullet hole, removing the coordinate; clicking the second bullet hole, an adjusted reticle appearing.
