Abstract

A point of aim shows where a weapon is aimed on a target. An electronic device determines an impact location on the target of a projectile fired from the weapon, determines a distance from the point of aim to the impact location, and moves the point of aim in order to sight the weapon to the target.

First claim

What is claimed is:

1. A method, comprising:
providing, by an electronic scope connected to a rifle, a visual indication as a point of aim that is visible through the electronic scope to show where the rifle is aimed on a target;
determining, by the electronic scope, a location of the point of aim on the target before a bullet is fired from the rifle;
determining, by the electronic scope, an impact location of the bullet on the target after the bullet is fired from the rifle;
determining, by the electronic scope, a miss of the bullet as a difference between the location of the point of aim on the target and a location of the impact location on the target; and
moving, by the electronic scope and in response to the electronic scope determining the miss of the bullet, the visual indication as the point of aim that is visible through the electronic scope toward the impact location so the location of the visual indication of the point of aim on the target aligns with the impact location of the bullet on the target.

2. The method of claim 1 further comprising:
determining, by the electronic scope, a bore temperature of a bore of the rifle;
retrieving, by the electronic scope and based on the bore temperature, an adjustment to the point of aim in order to compensate for effects of the bore temperature on a trajectory path of the bullet fired from the rifle;
moving, by the electronic scope, the point of aim according to the adjustment to compensate for the effects of the bore temperature on the trajectory path of the bullet fired from the rifle.

3. The method of claim 1 further comprising:
determining, by the electronic scope, a type of the bullet loaded into the rifle;
retrieving, by the electronic scope and based on the type of bullet loaded into the rifle, an adjustment to the point of aim in order to compensate for effects of the ammunition type on a trajectory path of the bullet fired from the rifle;
moving, by the electronic scope, the point of aim according to the adjustment to compensate for the effects of the ammunition type on the trajectory path of the bullet fired from the rifle.

4. The method of claim 1 further comprising:
determining, by the electronic scope, a shape of a vapor trail of the bullet fired from the rifle;
retrieving, by the electronic scope and based on the shape of the vapor trail, an adjustment to the point of aim in order to compensate for effects of environmental conditions on a trajectory path of a subsequent bullet fired from the rifle;
moving, by the electronic scope, the point of aim according to the adjustment to compensate for the effects of the environmental conditions on the trajectory path of the subsequent bullet fired from the rifle.

5. The method of claim 1 further comprising:
determining, by the electronic scope, a pattern of multiple impact locations of multiple bullets that struck the target;
calculating, by the electronic scope and based on the pattern, an adjustment to the point of aim in order to compensate for impact locations on the target that are not within a bullseye location on the target;
moving, by the electronic scope, the point of aim according to the adjustment to compensate for the impact locations on the target that are not within the bullseye location on the target.

6. The method of claim 1 further comprising:
determining, by the electronic scope, an identity of a shooter of the rifle;
retrieving, by the electronic scope and based on the identity of the shooter of the rifle, an adjustment to the point of aim in order to compensate for effects of jitter of the shooter when the shooter previously fired the rifle;
moving, by the electronic scope, the point of aim according to the adjustment to compensate for the effects of the jitter of the shooter.

7. The method of claim 1 further comprising:
determining, by the electronic scope, a distance between the location of the point of aim on the target and the location of the impact location on the target;
determining, by the electronic scope, an angle of a line that extends from the location of the point of aim on the target to the location of the impact location on the target;
moving, by the electronic scope, the point of aim an amount equal to the distance and at the angle in order to align the point of aim with the impact location.

8. The method of claim 1 further comprising:
examining an image that includes the point of aim and the impact location;
determining, based on examination of the image, the difference between the location of the point of aim on the target and the location of the impact location on the target;
sighting the electronic scope to the rifle based on the examination of the image.

9. An electronic scope, comprising:
a memory that store instructions;
a display that communicates with the memory; and
a processor that executes the instructions to display on the display a visual indication that is a point of aim that shows where a handheld firearm connected to the electronic scope is aimed on a target, to detect an impact location on the target of a bullet fired from the handheld firearm, to calculate a miss of the bullet that is defined by a distance and a direction between the visual indication that is the point of aim on the target and the impact location of the bullet on the target, and to move, in response to the miss, the visual indication that is the point of aim by the distance of the miss and in the direction of the impact location in order to sight the electronic scope such that subsequent bullets fired from the handheld firearm have impact locations at the point of aim.

10. The electronic scope of claim 9 , wherein the processor further executes the instructions to compare an image of the target before the bullet is fired from the target with an image of the target after the bullet impacts the target at the impact location.

11. The electronic scope of claim 9 , wherein the processor further executes the instructions to detect a speed of the target, to move crosshairs in the electronic scope to compensate for the speed of the target so a shooter of the handheld firearm is not require to lead the target while the target moves.

12. The electronic scope of claim 9 , wherein the processor further executes the instructions to capture an image of a mirage in a field of view of the electronic scope, to obtain an adjustment to the point of aim that is particular to the image of the mirage, and to move the point of aim on the display according to the adjustment.

13. The electronic scope of claim 9 , wherein the processor further executes the instructions to obtain identifying information about the handheld firearm connected to the electronic scope, to obtain an adjustment to the point of aim that is particular to the identifying information about the handheld firearm, and to move the point of aim on the display according to the adjustment, wherein the adjustment includes a distance and a direction to move the point of aim on the display based on a distance from the handheld firearm to the target.

14. The electronic scope of claim 9 , processor further executes the instructions to detect when the bullet is fired from the handheld firearm, to obtain a wind direction and a wind speed based in response to detecting that the bullet is fired from the handheld firearm, and to move the point of aim on the display to offset effects of the wind direction and the wind speed on bullets fired from the handheld firearm.

15. The electronic scope of claim 9 , wherein the processor further executes the instructions to detect when the point of aim on the display crosses a bullse
