PROBLEM TO BE SOLVED: To obtain an image processor where an output level and power consumption are kept equal between a conventional processing that outputs a two dimensional image projected on an image sensor and a processing that outputs a result of projection operation of the two dimensional image. SOLUTION: The image processor is provided with a plurality of unit pixel circuits 1a-1c, that output a pixel value in response to a luminous quantity of an incident light to an output line, and a plurality of read circuits that are placed in the unit of rows and columns of a plurality of the unit pixel circuits 1a-1c and read a pixel value of each of the unit pixel circuit 1a-1c and a result of projection operation in the unit of rows and columns. Then each unit pixel circuit configuring each row and column and each read circuit corresponding to the circuit are interconnected by an individual output line and the result of projection operation read in the compression processing indicates a mean value of pixel values of the unit pixel circuits 1a-1c configuring each row and column.
