The image processing and camera

control sections are designed to

operate independently to improve

image processing performance and

speed up multi-point autofocus.

The M340 Group of microcontrollers are ideal for digital video camera, digital still camera and camera lens control

applications. They incorporate analog circuits required for optical image stabilization, autofocus and auto-exposure control.
