PURPOSE: To minimize the number of picture elements within an image by reading image data from the central part of an array, and successively reading the image data from the center of the array to the outside. CONSTITUTION: The image data of four signal lines of a detector array are combined by a detecting circuit 50. When the signals of a line 1-4 are combined, for example, four multiplexers 62 are instructed to connect their first inputs to their outputs. By this operation, the signals from the line signal line 1-4 are inputted and applied to an adder 64, added by the adder 64, and transmitted to the output of the adder 64. The direction of transmitting to the multiplexer 62 is changed so that the signals from the other module buffer 60 can be successively combined by the adder 64, whereby each adjacent line of four lines of the detector array can be successively processed. Thus, the number of picture elements within an image can be minimized.
