Title:
IMAGE RECORDING DEVICE AND GUN
Document Type and Number:
WIPO Patent Application WO/2023/195503
Kind Code:
A1
Abstract:
This image recording device is provided with an image capturing unit capable of continuously capturing images in an aiming direction, an acceleration sensor, and an arithmetic processing unit for detecting an operation timing of a mechanism interlocked to a trigger operation of a gun, on the basis of an output value of the acceleration sensor, wherein the arithmetic processing unit: determines that a state in which an amount of change in the output value of the acceleration sensor is less than a predetermined first threshold is a state of rest; determines that a state in which the state of rest has continued for more than a predetermined time is an aiming state; upon detecting that the amount of change in the output value of the acceleration sensor while in the aiming state is greater than a predetermined second threshold at least equal to the first threshold, determines that the mechanism interlocked to the trigger operation of the gun has operated; and records images for a certain period including the timing, from among the images captured by the image capturing unit.
