A display apparatus and a displaying method thereof can improve picture quality. The display apparatus includes: a light emitting display; a camera module to take a picture; a brightness controller to generate a voltage corresponding to a gradation value of image data transmitted from the camera module based on a gamma curve, and to apply the generated voltage to the light emitting display; a controller to control the camera module and the brightness controller; and an image compensator to create a control value on the basis of an average of first brightness data corresponding to a predetermined region of a frame data transmitted from the camera module, and an average value of second brightness data transmitted from the controller corresponding to the other regions of the frame data. In the display apparatus, the controller resets at least one of amplitude and a gradient of the gamma curve on the basis of the control value. |
