Abstract:
1. A display apparatus comprising: a display unit; an image processing unit which processes an input image signal of an initial data bit and provides the processed input image signal to the display unit; a storage unit which stores a coefficient of color temperature; and a controller which obtains an average picture level of the input image signal, and controls the image processing unit to convert the input image signal to an image signal of a first data bit larger than the initial data bit, to multiply the image signal of the first data bit by the color temperature coefficient, and to further multiply the image signal of the first data bit by the obtained average picture level, wherein the controller controls the image processing unit to convert the image signal of the first data bit to an image signal of a second data bit smaller than the first data bit while noise shaping the image signal of the first data bit by adjusting brightness values of the image signal of the first data bit.
