To provide an apparatus and method for realizing a processing with which a pixel gravity center control can be conducted when a pixel number reduction image is generated in an image pickup apparatus. A pixel unit configured to output a pixel addition signal obtained by adding output pixel signals from pixels having different sensitivities to each other and a pixel information synthesis unit configured to execute a weighted addition processing of multiplying plural pixel addition signals output from the pixel unit by a previously set gain and calculate a configuration pixel value of a pixel number reduction image where a total number of pixels is lower than a number of pixels of the pixel unit are provided. A control on gravity center positions for respective pixels constituting the pixel number reduction image is executed through the pixel addition signal generation processing by the pixel unit and the weighted addition processing by the pixel information synthesis unit. For example, a gravity center position control to evenly arrange the gravity center positions for the respective pixels constituting the pixel number reduction image in the pixel unit is executed. Through this processing, it is possible to generate a high quality image in which a generation of jaggies or the like is suppressed. |
