Video recording device for a targetable weapon
First Claim
1. A method for recording data in response to a discharge of a weapon along a target line, comprising:
- sensing at least one discharge of said weapon with a weapon discharge sensor and in response to each of the at least one discharge of said weapon, generating a weapon discharge sensor output signal;
repeatedly storing video image data comprising video frames within a semiconductor memory within a video recording device mounted to said weapon;
in response to the detection of each said weapon discharge sensor output signal, preserving in said semiconductor memory within said video recording device, video image data corresponding generally to an area surrounding said target line and corresponding to at least one frame stored within said semiconductor memory prior to the respective discharge sensor output signal and at least one frame stored within said semiconductor memory subsequent to the respective discharge sensor output signal.

Abstract
A compact video image recording device which is mountable to a gun and useful for recording video images before and after the firing of the gun. The recording device includes a camera comprising a lens and a video image sensor. The video recording device is mounted on the gun such that the viewing area of the camera includes the target area of the gun. The video image sensor generates an electronic signal representative of a video image impinging the respective sensor. The output of the image sensor is processed and generally employed to produce frame data which are successively stored in successive frame locations of a semiconductor memory organized as a circular buffer memory while the video recording device is in an active state. Upon the firing of the gun, additional frames are stored in the buffer memory for a short period of time and a portion of the buffer memory is employed to preserve a video record of the shooting both before and after the event. Additional frames are successively stored in the unused portion of the buffer memory. In the event of a further firing of the gun, an additional portion of the buffer memory is dedicated to preserving the image data associated with subsequent firing incident. This process may be repeated until the buffer memory is full in the event the gun is repeatedly fired. A video record is thus generated which documents the circumstances preceding and following the firing of the gun.
