Abstract:
An image processing apparatus for inputting an image signal, performing image processing and outputting the processed image signal, comprising:pixel registers for storing a plurality of pixel signals included in the image signal and outputting pixel signals in parallel;power calculating means for calculating, in parallel, respective power values of the pixel signals output from said pixel registers;memory for storing, in parallel, the respective power values of the pixel signals calculated by said power calculating means;multiplying means for multiplying, in parallel, each of the power values stored in said memory by a corresponding constant;summing means for summing each of values resulting by said multiplying means;output means for holding summed values summed by said summing mean for each of the plurality of pixel signals and outputting the summed values in an order of raster scanning; andcontrol means for controlling the calculations performed by said power calculating means, said multiplying mean, said summing means and said output means in accordance with a control program for implementing an equation where a function utilized in said image processing is approximated by a polynomial,wherein said power calculating means, said multiplying means and said summing means, each includes a plurality of arithmetic logical units, the number of the arithmetic logical units corresponds to the number of plurality of pixel signals stored in said pixel registers.
