W99682BCD

•Support UART / USB Bus Host Interface.
•Easy for host to develop Camera function through UART or USB Command set protocol.
• Direct connect to CMOS and CCD image sensor:
• CMOS Image Sensor: AGILENT, HYUNDAI, IC MEDIA, MOTOROLA, OMNIVITION, PHOTOBIT, PIXART and TOSHIBA
• Supports real-time video resolutions up to 640X480 and still image resolutions up to 2048X2048
• High performance sensor DSP functions (includes black level compensation, color Interpolation, false color suppression, edge enhancement, color correction, gamma correction, AEC, AWB, contrast stretching, hue and saturation adjusting)

The W99682BCD is a high performance and highly-integrated DSC (Digital Still Camera) processor that it can preview, capture, compress, store, and display the digital still images or a short period of live video. In addition to processing still images, if connected to the PC through the USB, the W99682BCD based DSC can act as a PC camera, which captures real-time video (30 fps) to the PC.

An on-chip USB controller is deployed for data transfer between the W99682BCD based DSC and the PC.

Theompressed pictures on flash memory (or SDRAM) can be up-loaded to the PC through the USB, and also the  mpressed pictures on the PC can be downloaded to the DSC through the USB. In addition to transfer image data, the W99682BCD allows to download the programs of micro controller through the USB to update the external flash program ROM, which allows for end users with firmware upgrades through the Internet.

W99682BCD supports CCD and CMOS image sensors with high performance DSP functions including missing color interpolation, AE (Auto Exposure), AWB (Auto White Balance), Gamma Correction, edge enhancement, contrast stretching, hue and saturation adjusting etc.

W99682BCD has built-in the baseline JPEG codec for image compression and decompression, which corresponds to the ISO/IEC international standard 10918-1, with YCbCr4:2:2 or YCbCr4:2:0 components in interleaved scan.

W99682BCD also supports the Exchangeable Image File format (EXIF) to ensure data compatibility and  changeability.

W99682BCD implements full-speed USB controller complying with USB Spec. Rev. 1.1. W99682BCD includes six endpoints in which one Control transfer for control data, two isochronous transfer for video and audio data, two programmable bulk transfer for compressed image data and one interrupt transfer for status or event.

W99682BCD includes an 8032 compatible CPU core, a 6K-byte SRAM and two 16-bit programmable timers. The internal 8032 can be optional to disable and connects with external microcontroller for software development.

W99682BCD supports a flexible flash memory interface and can directly connect to CompactFlash and NAND type flash. It also supports the DMA data transfer between SDRAM, USB and flash memory.

W99682BCD integrates a TV encoder to support both NTSC and PAL output.
