STV0674 Datasheet | STMicroelectronics

.. ® Tri-mode CMOS digital camera co-processor Description The STV0674 is a flexible, scalable digital camera co-processor for use with the range of CMOS imaging sensor products from STMicroelectronics. The same chipset can be used for a wide range of digital imaging products with unique Features and price/performance points. The STV0674 is designed for use with CIF (352x288) or VGA (640x480) ST CMOS image sensors and provides full exposure control, color processing and mode control for these sensors. The STV0674 can be used to implement any of the following products: Low cost USB Webcam Camera - a two-chip solution providing up to 30 frames per second VGA simultaneous video and audio capture. Dual-Mode Camera - USB webcam and CIF or VGA digital still camera in a single product. Features s VGA or CIF CMOS sensor support s Hardware color processing and JPEG pression of image data s Still image capture s Tethered video operation over USB q Simultaneous video and audio capture USB for PC and Mac OS (in development) SDRAM for lower cost, (8 or 16 bit) FLASH for non volatile storage (Data + Code) Smartmedia Card for removable data storage EEPROM for code storage s USB q s Flexible external memory options q q q q .. s Record simultaneous video and audio direct to memory while untethered s Drivers for PC operating systems Win98, Win ME, Win2K and WIn XP. Tri-Mode Camera - USB webcam and digital still camera with the addition of a ‘camcorder’ mode to allow simultaneous video and audio capture directly to external memory for later upload to the PC.
