Abstract
An apparatus and a method that can efficiently generate a wide dynamic range image 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 by adding pixel values of a plurality of high sensitivity pixels and low sensitivity pixel information obtained by adding pixel values of a plurality of low sensitivity pixels are output as output pixel signals from pixels of different sensitivities from a pixel unit, these pixel information are combined in a pixel information combining unit, an output pixel value is determined, and an output image of a wide dynamic range is output. In the pixel information combining unit, a weight for the high sensitivity pixel information or the low sensitivity pixel information is changed according to brightness of a subject, weight addition of the high sensitivity pixel information and the low sensitivity pixel information is performed, a pixel value of an output image is determined, and the pixel value is output.
