A new optlcal detector for a high-speed AF control

This paper presents a new Optical Detector that can provide a high-speed AF control. The Optical Detector detect data to control AF, AE and AWB. The conventional Optical Detector detects only one characteristic data in a field, however, this new Optical Detector can execute high speed detection for AF control since it detects several characteristic data in a field. The new Optical Detector implements above function by switching filter coefficient every line.
