A display apparatus includes a tuner for selecting a desired channel; a decoder for decoding broadcasting signals (Y, U, V) inputted from the selected channel; a video processing unit for processing the decoded broadcasting signals into (R, G, B) signals; a gain adjustment unit for adjusting the gain value of the (R, G, B) signals processed by the video processing unit; a display unit for displaying the (R, G, B) signals the gain of which has been adjusted; and a control unit for detecting skin color from the (R, G, B) signals processed by the video processing unit and calculating luminance signal level to correct the luminance signal level of the (R, G, B) signals. The display apparatus can accurately correct skin color in low luminance level.
