Coding light filters structure for simultaneous increasing of television camera resolution and sensitivity
Abstract
Coding light filters (CLF) structure using in CCD- and CMOS- photo detectors color image obtaining, most defines the image quality. In article requirements to CLF for increase of sensitivity and resolution of a TV camera are formulated. The template of the synthesized SCL is presented. Com-puter modeling of five various CLF and their comparative analysis in objective and subjective parameters is carried out.
