Auxiliary processor and electronic device including the same

Abstract

Provided are an auxiliary processor and an electronic device including the same. The auxiliary processor includes a controller configured to receive an input image signal and a control signal including an input digital brightness value and convert the input image signal into a first data signal, a gamma compensator configured to generate a compensated gamma look-up table based on a reference gamma look-up table, a set voltage value, and new compensation parameters, wherein the reference gamma look-up table corresponds to a reference digital brightness value and the new compensation parameters are calculated based on luminance values for each grayscale associated with the input digital brightness value, and a data converter configured to convert the first data signal into a second data signal by using the compensated gamma look-up table. The set voltage value indicates a level of a driving voltage corresponding to the input digital brightness value.
