Camera Image Processors

Compatible with JPEG Image

BU6566GVW, BU6568GV

●Description

BU6566GVW/BU6568GV is a camera image processor compatible with standard JPEG.

Pin-to-Pin compatibility enable support for both standard and high-resolution cameras.

●Features

1)Built-in Camera Module Interface

function is available).
