Matsushita Electric Industrial Co Ltd exhibited a prototype drive recorder that records the front, rear and interior views of a vehicle using one interior and three exterior cameras at the 40th Tokyo Motor Show.

Each view is displayed on a quarter of the screen. After detecting the shock of an impact, the system records 30 seconds of images both before and after the impact on a 2-Gbyte SD memory card.

The recorder uses MPEG-4 video encoding technology. The total recording time on one SD memory card is three hours. The system also allows recording of a single view from one camera, extending recording time to 12 hours.

The prototype uses the company's "rear view camera" being marketed at ¥18,900 (US$165). Its image sensor is a color CCD with about 250,000 resolution. The frame rate is 30fps. The viewing angles are 134° horizontally and 103° vertically.

Matsushita also demonstrated displaying of an overhead view shot with four cameras in one of the four frames. In this case, the system uses a total of seven cameras including three for the drive recorder and four for overhead views.
