In the paper, an efficient super-resolution image processing is presented. We have developed a fast interpolation algorithm which is successfully implemented on the ARM-9 microcontroller board, AT91SAM9RL. The results have been compared to the previous works on both with the Matlab-based simulations and the hardware of DSP TMS320C5515. The developed algorithm has shown up to be an efficient method with less image-processing times for processing large size color images in acceptable processing time. The possible applications of super-resolution image processing are to digital cameras or photos where high resolution images are required for feature extractions.
