METHOD AND APPARATUS FOR DETECTING BACKLIGHT OF IMAGE

An apparatus for detecting backlight of image, comprising: a processor configured to convert a pixel value for each of a plurality of image frames based on a first threshold, and block the pixel value into a plurality of block regions to generate a converted frame, generate brightness cumulative data based on the converted frame, determine a block region in which a block value is maximum in the brightness cumulative data as a backlight candidate block region, classify the block regions into first and second regions based on a position of the backlight candidate block region and calculate a backlight score using the sum of block values for the block region of the first region and the sum of block values for the block region of the second region, and determine the image as a backlight image when the backlight score based on a second threshold.
