To make it possible to cope with an error in a hue or the like in the case of using such a CCD of lower quality or an analog circuit of lower quality as might otherwise raise a problem in the hue, a correction approximating straight line group information creating method/apparatus of a multi-divided reading CCD and a correction processing device manufacturing method/apparatus of a multi-divided reading CCD generate correction approximating straight line group information for one real shot optimum for corrections, at an adjusting stage from a plurality of pieces of primary correction approximating straight line group information generated in advance. At the shooting time, therefore, all pixels can be corrected for their individual kinds by making use of the correction approximating straight line group information for one real shot.
