TC5747 Datasheet, PDF (8/44 Pages) List of Unclassifed Manufacturers – Single Chip CMOS Imager with Integrated Image Signal Processor and JPEG Codec

TC5747 Data Sheet
Single Chip CMOS Imager
JPEG Codec
Real-time JPEG encoder and decoder for still images and M-JPEG for motion video
Compression of up to VGA YUV 422 format images
Decompression of up to VGA resolution, 4:2:2, 4:1:1, 4:2:0 format images
Programmable compression ratio, up to 1.8 bits/pixel for VGA image
JPEG compression is done in parallel with preview of the video on the LCD
Thumbnail image support
Portrait images for phone book
Compression and decompression from the internal memory
Compression can be done after scaling and overlay of frame and stamp data
Decompressed image can be resized and re-compressed
On screen display
On screen display overlay of up to QVGA (320x240) resolution, 4-bit OSD data color table
Support of up to two layers of OSD data. The first layer can be used to add frame of stamp to the
captured image. The second layer can be composed of one or two non-overlapping regions of OSD
for switching messages and icons. Each OSD window has its own 4-bit color table.
Support of 32x32 pixel cursor with 4-bit color table
Rotation of JPEG images display by 90⁰ or 270⁰
