LC82221L
Motion JPEG Decoder
Preliminary Overview
LC82221L full-color digital image data expansion that accepts data formats that essentially conform JPEG standard. With provision frame memory, this input output image data standard video formats. addition, also supports wide range image display functions using that frame memory. compared earlier JPEG ICs, this features simplified JPEG functionality greater emphasis display functions. Thus supports creation excellent costperformance ratio systems applications that require display system. Users select either image data output. Built-in color conversion circuit LC82221L supports image sizes 1024 pixels horizontal direction. range vertical sizes handled arbitrarily, since limited size DRAM provided. 3.3-V single-voltage power supply. power. display position display size set. marker support Horizontal vertical scrolling display functions Support overwrite display, which next data expansion displayed overwriting previously expanded image data
Features
High image quality image expansion using JPEG system Superlative cost performance achieved only providing decoding functions. built-in quantization tables. High-speed processing achieved using fixed Huffman tables. Application have these tables. Huffman tables, luminance data chrominance data, provided. Supports scaling factor parameters that allow quantization factor changed. DRAM code data buffering image data playback connected directly. Applications either DRAMs based sizes image handled structure system. However, 16-bit data path DRAMs must used. Image data output synchronization with image display synchronizing signal. Color structure code data Y:U:V=4:1:1. Dedicated code data input provided avoid loading host bus. transfers also supported.
