Abstract:
1. A display apparatus comprising: a light emitting display; a camera module for taking a plurality of pictures; a brightness controller for generating a voltage corresponding to a gradation value of image data of a frame for each of the pictures transmitted from the camera module based on a gamma curve, and for applying the voltage to the light emitting display; a controller for controlling the camera module and the brightness controller; and an image compensator for creating a control value based on an average value of first brightness data corresponding to a predetermined region of the frame transmitted from the camera module and at least one of respective average values of respective second brightness data corresponding to any other regions of the frame transmitted from the controller, wherein the controller is configured to reset a value selected from the group consisting of an amplitude and a gradient of the gamma curve based on the control value for each of the pictures, and wherein the image compensator is configured to create the control value before one of the pictures corresponding to the image date utilized to create the control value is displayed on the light emitting display.
