Abstract
The present invention provides a vehicle driving information storage apparatus capable of preserving condition changes of inside and outside of a vehicle and a driver as synchronized images. Inside a vehicle 1, a fisheye lens 5 is arrange at a position capable of simultaneously filming a driver's state and a state inside and outside the vehicle and filming is performed at a predetermined cycle and a predetermined number jmax of the latest images are always stored in the image storage unit M1. Upon detection of a driving condition sudden change such as a sudden brake and a collision, image update is performed the operations times of jmax−x1 (0<x1<jmax) and the image update is stopped so that x1 images before sudden change and jmax−x1 images after the sudden change are preserved in the image storage unit M1. By checking the images preserved in the image storage unit M1, it is possible to analyze the condition change of the driver and inside and outside of the vehicle before and after the sudden change. Since the conditions required for analysis have been filmed by a single fisheye lens 5, it is possible to store in complete synchronization the condition change of the driv…
