摘要：An apparatus and a method that can efficiently generate a wide dynamic rangeimage to which each piece of pixel information of a high sensitivity pixel and a low

sensitivity pixel is applied are realized. High sensitivity pixel information obtained byadding pixel values of a plurality of high sensitivity pixels and low sensitivity pixelinformation obtained by adding pixel values of a plurality of low sensitivity pixels areoutput as output pixel signals from pixels of different sensitivities from a pixel unit, thesepixel information are combined in a pixel information combining unit, an output pixelvalue is determined, and an output image of a wide dynamic range is output. In the pixelinformation combining unit, a weight for the high sensitivity pixel information or the lowsensitivity pixel information is changed according to brightness of a subject, weightaddition of the high sensitivity pixel information and the low sensitivity pixel information isperformed, a pixel value of an output image is determined, and the pixel value is output.
