An image detection processor of the present invention enhances the processing speed of the calculation of the center of gravity or the like of a target with a simple constitution. The image detection processor arranges a plurality of image detection processing elements-to-on a plane. Each image detection processing element includes an adder circuitwhich converts an output of a photoelectric conversion partinto digital signals and can receive the digital signals as an input in a matrix form. Cumulative adders are constituted by connecting the adder circuitsfor respective rows. Series adders-to-which are connected in series respectively receive outputs of final stages of cumulative adders of respective rows as inputs and can cumulatively add these outputs. The digital signals are selectively inputted to the cumulative adders using a row decoderand a column decoderand processed data of an image detected by photoelectric conversion partsof a plurality of image detection processing elements are outputted from the series adder-. Due to such a constitution, the processed data necessary for an image processing such as the calculation of the center of gravity can be produced at the time of transferring data thus realizing rapid processing.
