ASX340CS: 1/4-Inch Color CMOS NTSC/PAL Digital Image Sensor

Sensor Pixel Array

Image Flow Processor

Image and color processing in the ASX340CS are implemented as an image flow

processor (IFP) coded in hardware logic. During normal operation, the embedded

microcontroller will automatically adjust the operation parameters. The IFP is broken

down into different sections, as outlined in Figure 9.
