Abstract:
An apparatus for high speed convolution comprising:an accumulative image data generating means for converting an input image of a camera to digital image data, adding the converted image data to image summation data from an origin on a present horizontal line to a previous pixel, and adding the result value to a pixel value in a rectangular area formed by an origin and pixels on the line previous to a present pixel, to generate an accumulative image data; a corresponding area data calculating means for extracting a predetermined number of partial area data from the accumulative image data generated from the accumulative image data generating means, selectively adding and subtracting the extracted partial area data to obtain image summation data of the corresponding area, and outputting a mask step value corresponding to said corresponding area; and a pixel convolution value outputting means for multiplying the corresponding area image data obtained from the corresponding area data calculating means by the corresponding mask step value and summing the multiplication results to output a pixel convolution value.
