PROBLEM TO BE SOLVED: To obtain an image signal which can reproduce a high resolution image distinct to the details from the CCD output of a singe plate type camera through class sorting adaptive processing corresponding to the part of an oblique line or a thin line of an image. SOLUTION: A class tap extraction circuit 32 extracts a plurality of pixels in the vicinity of each target pixel of an input image signal and the signal value of the plurality of pixels in the vicinity of the target pixel is subjected to ADRC processing thus generating first feature information. An oblique line/ thin line extraction circuit 31 extracts the signal value of a pixel at the steep edge part of the input image signal as second feature information. A class sorting circuit 34 determines one class based on the first feature information and the second feature information and an adaptive processing circuit 37 generates a pixel having a color component different from that of the interesting pixel based on that class.
