ABSTRACT:
In an image pickup apparatus, an interpolation signal for interpolating a discrepancy of registration is calculated from signals of (M.times.N) pieces of arranged elements (M, N being an integer, respectively) the positions of which on a light receiving plane are mutually adjoined with each other among arranged elements corresponding to signals in 2 fields which are continuously output from the respective image pickup elements, whereby the registration error can be corrected. An image pickup element has such a structure that signals having the same element number as an arranged element number corresponding to mutually continuous 2 field signals among the signals read during the normal interlace operation are entirely independently read every 1 field. By utilizing such an image pickup element having the element numbers two times higher than that of the conventional element, the registration error is interpolated from the signals of (M.times.N) pieces of the mutually adjoining arranged elements corresponding to the 1 field signal.
