Abstract
A display driving device, which adjusts a brightness of an image on the basis of an ambient illumination even without an increase in amount of power consumption, includes a controller determining a clipping ratio for clipping input image data by using an ambient illumination value when the ambient illumination value is input thereto, a gain calculator calculating a frame gain which is to be applied to the input image data, based on the clipping ratio, an input image clipping unit clipping the input image data by applying the frame gain in the input image data, and a gamma converter gamma-converting clipped input image data to generate output image data.
