IPC: G03B13/36
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To form an AF evaluation value suitable for the characteristic and photographing state of an image pickup lens system. SOLUTION: A line memory 40 stores one horizontal line of a focusing detection area from image pickup data. A discrete cosine transforming circuit 42 performs the orthogonal transformation of the stored data of the line memory 40.
