■ Overview
The MN673274 is designed for surveillance and PC input cameras. In addition to the basic functions of luminance signal and chrominance signal processing, it also integrates microcontroller functions (ALC, AWB, and AGC) and SSG, CG, and I2C-bus circuits on a single chip.

■ Features
• Input: Analog signal (A/D converter input)
