Sensor arrangement for film scanner to provide electrical image signals with sensor made up of parallel lines of sensor pixels

摘要

CCD or CMOS sensor is made up of several sensor lines (23) of sensor pixels, individually read by shift registers. Lines are at distance (D) apart so one sensor line scans even and other sensor line scans odd image lines. Charge shift register (22) is controlled so charges of two neighboring pixels are added at end of both shift registers before converted to voltage output, so that neighboring pixels in horizontal direction are added before signal processing, : INDEPENDENT CLAIM included for film scanner.
