Abstract
A camera interface circuit for a barcode scanner includes a binary conversion block and a selection module. The binary conversion block receives image signals from a camera, and converts gray levels of each pixel in each image frame into binary codes. The selection module alternately provides binary codes of one image frame and image signals of a consecutive image frame as outputs.
