MUNICH, Germany Automotive OEMs, accident researchers and insurance companies increasingly are interested in an equipment component for cars which in aircraft has been established as standard equipment already for a long time: A drive recorder. This 'black box' could record accident data in realtime, shedding light on the cause of an accident.
Now Japanese chip manufacturer Seiko Epson Corp. has developed a controller chip for such applications. The device stores image data from two independent cameras over extended periods of up to 24 hours on a High-capacity SD card. For this purpose, the chip disposes of two hardware 30 fps VGA JPEG encoders. In addition, the S2S65A30 offers a source image correction function in order to adapt to environment light conditions. The device also supports JPEG decoding for on-site playback.
Other features include a USB 2.0 interface for PC connectivity, an interface with acceleration sensors through ADC and an event counter to process the vehicle speed pulses and enabling the device to time-stamp the records.
The controller is available in small quantities now; volume shipment is scheduled for November.
