Abstract:
A vehicle driving information storage apparatus that stores an image of a driver's state and a vehicle state, said apparatus comprising:a wide angle lens configured and positioned to simultaneously capture a driver's state, a state inside a vehicle, and a state outside a vehicle; a signal output that outputs a digital signal of an image captured by said wide angle lens; an image storage that stores and is updated with the digital signals output from said signal output at a predetermined frequency; a condition change detector that detects a change of a driving condition of the vehicle; a necessary image data preserver that inhibits an update of the digital signals after detection of the change by said condition change detector; a latest image storage that stores a plurality images from the digital signals output from said signal output and updates with the digital signals output from said signal output on a first-in, first-out (FIFO) basis at a predetermined frequency; and a necessary image data preserver that allows an update of images on FIFO basis a predetermined number of times after detection of a driving condition change by said condition change detector and inhibiting update of images thereafter.
