Ordering number : EN*5685 COMS IC LC82104 Color Image Processing IC for Fax and Scanner Applications Preliminary Overview The LC82104 converts analog image signals from a CCD and contact image sensor to precise multi-valued image data using a built-in 8-bit A/D converter and internal image-processing functions. The LC82104 includes a 6-bit reference potential setting D/A converter for the 8-bit A/D converter and CDS function, and produces high-quality multi-valued data by performing shading correction for all pixels, color balance adjustment, and gamma conversion with support for arbitrary gamma curves. It also includes a multi-value data resolution conversion function, and thus can support input from and output to systems with different resolutions.
