<p>PROBLEM TO BE SOLVED: To accelerate reading speed without decelerating the writing speed of image information by storing the image information of respective blocks, which are processed with a processing means while controlling an input means, in the continuous areas of a storage means. SOLUTION: This image information processor stores the image information of respective blocks processed by a processing unit 3 in the continuous areas of an image information storage memory 2 in advance while using an address generator 11 and a data buffer 12 of an input unit 1. Originally, the writing speed of the image information storage memory 2 is remarkably higher in comparison with data speed but image information is written in the image information storage memory 2 corresponding to the data speed and there is a little margin in processing for writing the image information in the image information storage memory 2 without accelerating the apparent writing speed of the image information storage memory 2 rather than the data speed. On the other hand, it is not necessary to match speed for reading image information from the image information storage memory 2 with the data speed and acceleration is enabled corresponding to the processing speed of the processing unit 3.</p> |
