DESCRIPTION
VV5404 and VV6404 are highly integrated CMOS VLSI sensors which enables high standards of performance and image quality at a very cost-effective price point. The 356 x 292 monochrome device offers one of the simplest routes currently available to design-in of imaging applications, while the colour device is ideal for low cost PC camera applications. Both devices incorporate a comprehensive range of on-board controls eliminating the need for additional support chips. Onchip A/D conversion provides 8 bit digital output and the device set up is fully automatic via the built-in automatic black level calibration algorithm. Exposure and gain settings are programmable and operation is controlled via a serial interface. This sensors offer variable frame rates of up to 30 frames per second and a 4 wire digital video bus. The digital interface also provides a tri-stateable data qualification clock and frame synchronisation signal. Hand-held products, in applications such as PDAs, bar code scanning or automatic meter reading, will benefit from the low power requirements and from the inbuilt sleep and power down modes.
