We have implemented a novel LED driving circuit to evoke subjective super-resolution effect on grayscale images by use of FPGA. An 8-bit grayscale image is oversampled and coded into multiple subframes, which are shown on an LED panel at a high frame rate. We have confirmed subjective super-resolution.
