Claim 3:
4. Electronic equipment, comprising:
a solid-state imaging device that includes a pixel array portion in which a plurality of pixel unit groups are arrayed, the pixel unit group being constituted by pixel units disposed in a 2×2 matrix, the pixel unit being constituted by pixels disposed in an m×m (m is a natural number of 2 or greater) matrix, and the pixel including a photoelectric conversion unit and a color filter formed to correspond to the photoelectric conversion unit, in which each of the pixel unit groups includes an R filter transmitting red light and a C filter transmitting cyan light having a complementary color relation with the red light as the color filters in a first pixel unit among four pixel units constituting the pixel unit group, includes a G filter transmitting green light and an M filter transmitting magenta light having a complementary color relation with the green light as the color filters in each of second and third pixel units, and includes a B filter transmitting blue light and a Y filter transmitting yellow light having a complementary color relation with the blue light as the color filters in a fourth pixel unit;
an optical lens that forms image light from a subject into an image on an imaging surface of the solid-state imaging device; and
a signal processing circuit that performs signal processing on a signal output from the solid-state imaging device,
wherein the signal processing circuit includes a luminance value calculation unit that adds pixel values of image pixels having color information of the colors red and cyan in each of pixel groups corresponding to the first pixel unit in a mosaic image corresponding to an array of the color filters obtained from the signal to calculate a luminance value of one image pixel, adds pixel values of image pixels having color information of the color green and magenta in each of pixel groups corresponding to the second and third pixel units to calculate a luminance value of one image pixel, and adds pixel values of image pixels having color information of the colors blue and yellow in each of pixel groups corresponding to the fourth pixel unit to calculate a luminance value of one image pixel,
wherein the signal processing circuit includes a binning processing unit that generates an RGB mosaic image by adding pixel values of image pixels having only color information of the color red in each of pixel groups corresponding to the first pixel unit in a mosaic image corresponding to an array of the color filters obtained from the signal to set the pixel values as a pixel value of one image pixel having only color information of the color red, adding pixel values of image pixels having only color information of the color green in each of pixel groups corresponding to the second and third pixel units to set the pixel values as a pixel value of one image pixel having only color information of the color green, and adding pixel values of image pixels having only color information of the color blue in each of pixel groups corresponding to the fourth pixel unit to set the pixel values as a pixel value of one image pixel having only color information of the color blue,
wherein the binning processing unit generates the RGB mosaic image and generates a CMY mosaic image by adding pixel values of image pixels having only color information of the color cyan in each of pixel groups corresponding to the first pixel unit in a mosaic image corresponding to an array of the color filters obtained from the signal to set the pixel values as a pixel value of one image pixel having only color information of the color cyan, adding pixel values of image pixels having only color information of the color magenta in each of pixel groups corresponding to the second and third pixel units to set the pixel values as a pixel value of one image pixel having only color information of the color magenta, and adding pixel values of image pixels having only color information of the color yellow in each of pixel groups corresponding to the fourth pixel unit to set the pixel values as a pixel value of one image pixel having only color information of the color yellow, and
wherein the signal processing circuit includes an HDR image generation unit that converts the CMY mosaic image into an RGB mosaic image and synthesizes the converted RGB mosaic image and the RGB mosaic image generated by the binning processing unit to generate a high dynamic range image.
