<p>The image processing apparatus of this invention includes a novel data processing unit and memory unit. The data processing unit includes a two- to one-dimensional address coordinate value transformation unit, a two-dimensional coordinate transformation unit, an inter-pixel data calculation device and memory unit. The two- to one-dimensional address coordinate value transformation unit transforms between a two-dimensional address coordinate value and a one-dimensional address coordinate value. The two-dimensional coordinate transformation unit transforms a coordinate value (x, y) on an x-y coordinate system within a predetermined area into a coordinate value (X, Y) on an X-Y coordinate system within a predetermined area. The inter-pixel data calculation unit performs a binomial operation between two pixel data. The memory unit is arranged to have a variable bit length to be parallel accessible. The image processing apparatus can realize good image processing without making the apparatus large in size. <IMAGE></p> |
