An Electronic camera, comprising: an image pickup device which includes a light-receiving plane photoelectrically converting a subject image and allows any randomly designated partial image area to be read out from a maximal image area used to generate an image with a maximum number of pixels on the light-receiving plane; a partial image area position detecting section which detects positional data of said designated partial image area with respect to said maximal image area; an image correcting value calculating section which calculates maximal image correcting values based on a characteristic of the entire maximal image area, outputs said maximal image correcting values that are used for image processing of image signals of said entire maximal image area and extracts applied correcting values from said maximal image correcting values based on said positional data of said designated partial image area, said applied correcting values being correcting values of said maximal image correcting values at a position corresponding to said designated partial image area; an image processing mode selecting section which selects one of said applied correcting values and partial image correcting values as correcting values used for performing image processing on image signals of said partial image area in an image processing section, wherein said image correcting value calculating section further calculates said partial image correcting values based only on a characteristic of the designated partial image area and outputs said partial image correcting values that therefore are optimized for image processing of said designated partial image area. an image pickup device which includes a light-receiving plane photoelectrically converting a subject image and allows any randomly designated partial image area to be read out from a maximal image area used to generate an image with a maximum number of pixels on the light-receiving plane; a partial image area position detecting section which detects positional data of said designated partial image area with respect to said maximal image area; an image correcting value calculating section which calculates maximal image correcting values based on a characteristic of the entire maximal image area, outputs said maximal image correcting values that are used for image processing of image signals of said entire maximal image area and extracts applied correcting values from said maximal image correcting values based on said positional data of said designated partial image area, said applied correcting values being correcting values of said maximal image correcting values at a position corresponding to said designated partial image area; an image processing mode selecting section which selects one of said applied correcting values and partial image correcting values as correcting values used for performing image processing on image signals of said partial image area in an image processing section, wherein said image correcting value calculating section further calculates said partial image correcting values based only on a characteristic of the designated partial image area and outputs said partial image correcting values that therefore are optimized for image processing of said designated partial image area.
