Description
The CXD3172AR is a signal processor LSI for Ye,Cy, Mg and G single CCD color cameras. In addition to basic camera signal processing functions, it includes an AE/AWB detection circuit, a sync signal generation circuit and an external sync circuit, etc. This chip also has a built-in microcontroller to realize basic camera functions such as AE/AWB without an external microcomputer.
