IMAGE RECORDING DEVICE

PROBLEM TO BE SOLVED: To provide an image recording device capable of providing accurate information for analyzing the cause of an accident. SOLUTION: An imaging unit 1 outputs a pair of image data picked up by cameras 11 and 12 to a saving unit 4. A trigger unit 3 detects change of a vehicle etc., and generates a trigger signal. On receiving the trigger signal generated by the trigger unit 3, a parameter calculation unit 2 calculates camera parameters of the imaging unit 1. On receiving the trigger signal, the saving unit 4 saves the image data picked up by the imaging unit 1 in a prescribed image saving period including the reception time of the trigger signal while associating them with the camera parameters calculated by the parameter calculation unit 2.
