Abstract
A pixel calculating device for performing vertical filtering that includes 16 pixel processing units 1 to 16 and an input buffer group storing 16 pieces of pixel data and filter coefficients. Each of the pixel processing units performs operations using the pixel data and a filter coefficient supplied from input buffer group , and then acquires pixel data from an adjacent pixel processing unit. Further operations are performed by each of the pixel processing units using the acquired pixel data and operation results are accumulated. Filtering is carried out through a repetition of this acquiring and accumulation process, the number of taps being determined by the number of repetitions.
