Abstract
A display apparatus and a method of displaying an image using the display apparatus. The display apparatus includes a classifier to detect whether a pixel of each line of sequentially input frames of an input image is a black pixel of a letter-box area, a counter to count a number of black pixels detected in each line, a determiner to determine a maximum value of consecutive black pixels in each line, a letter-box detector to detect a boundary of the letter-box area in each frame using the number of black pixels and the maximum value of consecutive black pixels of each line, a boundary determiner to determine final boundaries of the letter-box area by determining a line as one of the final boundaries of the letter-box area if the line is detected as the boundary of the letter-box area a predetermined number of times or more in the frames of the input image, and an adjuster to adjust a size of the input image such that an image area within the final boundaries of the letter-box area is fit to a size of a screen.
