[20a-PA1-8] Implementation of FPGA-Based LED Driving Circuit for Subjective Super-Resolution Display of Grayscale Images
Keywords:Subjective Super-Resolution, LED, FPGA
Subjective super-resolution refers to a display method in which image data adjacent to a low-density LED element is switched at high speed to be displayed to give an illusion of resolution higher than that of an actual LED panel. The purpose of this paper is to implement subjective super-resolution display in grayscale on a high-speed LED panel. FPGA (field-programmable gate array) is used to control an LED panel at an extremely high frame rate. The averaged image display and the subjective super-resolution display were compared. Observers perceived that the subjective super-resolution display represents more smooth fonts.
