摘要：PROBLEM TO BE SOLVED: To provide an image processing device for converting image data with a less memory capacity. SOLUTION: In such a case that image data having 640×480 dots is converted into image data having 1280×960 dots, a memory 10 for processing 640×16 lines is prepared. Initially, actual data for eight lines are developed in the upper half parts of the memory 10 and are processed, and then the data are developed in the lower half parts of the memory and rare processed. With the repetitions of these steps, four bits from the most significant bits of the coordinate values of four actual data calculated from desired dots on virtual coordinates are used as line numbers ('0' to '15') of the actual data developed in the memory 10.
