Claim:
An image pickup apparatus comprising: an image pickup element in which a plurality of color filters are respectively arranged on a plurality of pixels arrayed two-dimensionally in a horizontal direction and a vertical direction, each of the pixels including a photoelectric conversion element; a storage device that stores information for correcting a signal value of each of the pixels of the image pickup element; and a correction device that corrects the signal value of each of the pixels of the image pickup element using the information stored in the storage device, wherein the plurality of the pixels of the image pickup element share a specific circuit element on a multiple-pixel basis, the plurality of the color filters of the image pickup element are arranged such that a basic array pattern is repeated in the horizontal direction and the vertical direction, the basic array pattern mixedly including three or more color types of the color filters and having an arrangement period different from an arrangement period of a sharing structure pattern including the specific circuit element and the multiple pixels, the storage device stores a plurality of first correction coefficients and a plurality of second correction coefficients, the plurality of the first correction coefficients respectively corresponding to colors of the plurality of the color filters of the image pickup element, the plurality of the second correction coefficients respectively corresponding to a plurality of relative positions of the pixels to a position of the specific circuit element of the image pickup element, and when the correction device targets each of the plurality of the pixels of the image pickup element and corrects the signal value of each pixel of interest, the correction device selects a first correction coefficient corresponding to the color of the color filter on the pixel of interest from the plurality of the first correction coefficients stored in the storage device, selects a second correction coefficient corresponding to the relative position of the pixel of interest from the plurality of the second correction coefficients stored in the storage device, and performs a calculation with the selected first correction coefficient and the selected second correction coefficient, with respect to the signal value of the pixel of interest.
