IMAGE DATA THINNING OUT/INTERPOLATION DEVICE, IMAGE DATA THINNING OUT/INTERPOLATION METHOD, IMAGE DATA THINNING OUT/INTERPOLATION PROGRAM AND COMPUTER-READABLE RECORDING MEDIUM FOR RECORDING THE IMAGE DATA THINNING OUT/INTERPOLATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image data thinning out/interpolation device that interpolates color image data with high image quality at a high-speed. SOLUTION: (1) An original image recorded on an HDD is read under the instruction from a CPU1, (2) and the CPU1 reads an image on a RAM1 and compresses the image. (3) The CPU1 writes the compressed data to other areas of the RAM1. (4) A RAM2 in a printer records the compressed data under the instruction of the CPU1. (5) A CPU2 in the printer reads the compressed data to obtain a decoded value and to expand the image. (6) The CPU2 writes data after expansion to the RAM2. (7) Then the printer prints out the expanded data by a prescribed procedure of 'applying variable power'.
