PURPOSE:To execute diverse image processing with a simple constitution by composing the processor of an image memory, a line delaying means, an image data enlarging means, a binarizing means, the outline detecting means of a binarized image, and an image data replacing means. CONSTITUTION:One picture is fetched into an image memory 302. Next, the reading speed of the memory 302 is made half, and the image data are transferred to a line delaying circuit 304. Next, the image data of the circuit 304 are rotated once. Thus, the data in the first line of still image data are enlarged two-fold in an X direction. Next, by the above-mentioned circuit, the still image data are made two-fold also in a Y direction. A binarizing circuit 307 binarizes the enlarge-processed image data and supplies them to a line delaying circuit 308, an outline detecting circuit 309 and an AND gate 316. A data selector 312 replaces the image data in the part, in which the binarized image data are logic 1, with superimpose level data. The data selector 313 replaces the above-mentioned image data with outline level data. Thus, the outline part is made into the image to be contrasted. |
