MN673273
Signal-Processing LSI for Multimedia Camera
I Overview
The MN673273 is a signal processing LSI for digital cameras
inputting to computer. In addition to the basic functions of
luminance signal and chrominance signal processing, the
MN673273 integrates microcontroller functions (ALC,
AWB, and AGC), SSG, and CG on a single chip.
I Features
• Input: Analog signal (A/D converter input)
• Outputs: Digital outputs
