PROBLEM TO BE SOLVED: To obtain the image data of desired compressibility by changing the compressibility of encoded image data. SOLUTION: An image file inputted part 502 inputs an image file including compressed image data, and when the compressibility of the inputted image data is decided, compressibility changing part 507 performs changing to the decided compressibility. In such a case, the code of an area of no interest of the image is eliminated and the compressibility of the image data is changed, or the code of an area of interest in the image data is eliminated and the compressibility of the image data is changed in the case the compressibility cannot be changed to a desired value only by the aforementioned procedure. |
