This paper introduces a feedback-type image processing architecture that can enhance image contrast without further digital image processing technique, e.g. histogram equalization. Compared with the conventional open-loop imaging system, the images derived by the proposed method has a full-range histogram without causing image distortion, and this is difficult to attain for open-loop imaging system.Feedback; Histogram equalization; Image contrast; Image processingImage processing; Imaging systems; Image contrast; Medical imaging; analog digital converter; article; contrast; feedback system; histogram; image processing; microcomputer; signal noise ratiojournal article10.4015/S10162372020003102-s2.0-0037175278
