This paper proposes an image display processing system that reduces the core performance of the processor allocated in the image display, thereby enabling the use of a less expensive low-performance processor. Essentially, the proposed system supports a high-resolution image display function in an electronic picture frame (EPF) module using a low-performance processor based on converting HD image data at a 15 Hz frame rate into HD image data at a 60 Hz frame rate for use in a digital TV system. As a result, the proposed system can reduce the processor performance to a level corresponding to an image display with a low frame rate, thereby reducing the product cost and allowing various additional functions. Finally, the proposed system is implemented to confirm its effectiveness.
