Abstract: PURPOSE: A method and system for controlling a light emitting module are provided to implement an image with high quality by improving a contrast ratio and brightness of an image. CONSTITUTION: A first reference value is obtained by applying Otsu's algorithm to an image comprised of a plurality of pixels(S110). The average brightness value of the pixels is obtained(S120). A second reference value is calculated by using the first reference value and the average brightness(S130). The pixels are binarized to 0 and 1 by comparing the individual brightness value of the pixels with the second reference value(S140). A ratio of the number of the pixels with 1 to the total number of the pixels is compared with a preset critical value(S150). The brightness of the pixels is controlled by applying boost algorithm(S180).
