STMicroelectronics (ST), Imaging Division (formerly VLSI VISION Ltd.), has utilised its extensive experience in designing imaging sensors for the digital still camera market to develop chipsets for modular systems which will provide the core of a highly cost-competitive new standard in consumer digital stills cameras (DSC).
The Low Cost Digital Camera chipsets from ST, incorporating a CMOS imaging sensor and STV0680A co-processor (formerly DCA1 ) enable camera manufacturers to offer an end product which is genuinely price competitive with traditional ‘point and shoot’ film-based cameras.
• CIF (352 x 288) or VGA (640 x 480) resolution sensor
• Using 64MBit memory, 80 picture storage capacity in camera (CIF), 26 (VGA), or 320 (QCIF).
• Using 16MBit memory, 20 picture storage capacity, in camera (CIF), or 80 (QCIF)
• USB/RS232 interface options
• Evaluation kit available
• Low power consumption (typically 75mA) for complete camera and low system cost per pixel
• High speed picture upload with USB
• USB tethered video mode gives a QCIF resolution videoconferencing camera with VfW support
• ‘Continuous’ mode for capturing image sequences (while untethered) and downloading to AVI file format
• Memory refresh allows picture retention when camera is in standby mode with very low current consumption
• TWAIN/Video for Windows driver support
• Numeric LCD panel supported
• Colour processing and pixel defect detection/correction software available under license as SDK for development of OEM software. The license to use the colour algorithm (embedded in the PC driver software) is included in the price of the chipset.
