摘要：PURPOSE:To shorten the time of read access to the frequency distribution result of one density value from outside and to reduce the scale of a circuit which controls the external access. CONSTITUTION:This image processor has selectors 50 and 53, a memory 52, and an adding circuit 51 which calculates the frequency distribution of density values of an image in an optional area, and a frequency distribution monitor circuit 10 and a bit array selecting circuit 11 which compare the output data width of the calculation result with external access data width and perform control according to the large/small comparison result so as to match the output data width of the density value frequency distribution calculation result with, for example, the external access data width.
