IMAGE PICKUP UNIT AND IMAGE PICKUP METHOD

摘要

PROBLEM TO BE SOLVED: To eliminate a noise in a moving picture caused by deficiency in a luminous quantity in the case of image pickup or the like. SOLUTION: Imaging light is made incident onto a CCD 2 via a lens 1. The CCD 2 of this image pickup unit converts the incident imaging light into an electric signal. A classification adaptive processing section 5 receives a picture signal generated on the basis of the electric signal. The classification adaptive processing section 5 classifies the picture signal on the basis of a class tap segmented from the received picture signal and applies an arithmetic operation of linear combination to the picture signal by using a prediction coefficient decided in advance for each class and a prediction tap segmented separated from the picture signal. The prediction coefficient is decided for each class by using the picture signal not including a noise as a teacher signal yk and using a signal adding the noise to the teacher signal yk as a pupil signal. Through the processing above, the noise can effectively be eliminated even from a moving picture.
