The present invention relates to an image pickup apparatus which can produce a color and sensitivity mosaic image which can be converted into a color image signal having a wide dynamic range by performing a predetermined image process. Light receiving elements of a CCD image sensor are arranged in a lattice arrangements where attention is paid to the color G irrespective of the sensitivities. Where attention is paid to the color R irrespective of the sensitivities, the light receiving elements are arranged on every other line. Also where attention is paid to the color B irrespective of the sensitivities, the light receiving elements are arranged on every other line similarly. Consequently, where attention is paid only to the colors of the pixels, the pattern P2 has a Bayer arrangement. A mosaic arrangement of a color is realized by disposing an on-chip color filter on an upper face of the light receiving elements of the CCD image sensor. A mosaic arrangement of a sensitivity is realized by an optical method or an electronic method. The present invention can be applied, for example, to a CCD image sensor built in a digital camera.
