PROBLEM TO BE SOLVED: To provide an image processing device preventing image quality deterioration when memory overflow occurs. SOLUTION: A data storage section 21 converts drawing data received from a clipping section 20 to intermediate data and stores in an intermediate data storing area 24. At this time, if the intermediate data cannot be saved in the intermediate data storage area 24, fall-back processing is executed for the intermediate data. On the other hand, compressed image data compressed in an image compression section 23 are saved in a compressed image data saving area 25. When the compressed image data cannot be saved in the compressed image data storage area 25, fall-back processing is executed for the compressed image data, and the compressed image data alone are developed into bitmap data and compressed, and saved as new compressed image data. At this time, as the intermediate data remain as they are, image quality deterioration can be prevented. |
