Patent ID: 8705135

Claim:
A display control apparatus for executing gamma correction on input image data of an input image to be displayed in a display apparatus, the display control apparatus comprising: a plurality of storage circuits storing a plurality of gamma data sequences, said display control apparatus is configured to receive the plurality of gamma data sequences and to store each gamma data sequence of said plurality of gamma data sequences in a corresponding storage circuit of said plurality of storage circuits; and a terminal receiving a measurement signal of a sensor for measuring elements of the environment surrounding said display control apparatus; a gamma data terminal receiving a gamma data sequence corresponding to gamma characteristics of said display apparatus; a look-up-table (LUT) creating circuit creating a LUT for gamma correction according to a gamma data sequence of said plurality of gamma data sequences selected according to said measurement signal; and a grayscale converting circuit converting grayscale values of said input image data into gamma-corrected grayscales according to said LUT; wherein said gamma data sequence comprises 2 k gamma data addresses each having a corresponding gamma data value that is a single-bit, the gamma data addresses corresponding to grayscale values of the image data after the gamma correction, k is a positive integer indicating the bits of resolution of the gamma-corrected grayscales, and wherein in response to the gamma data value of a gamma data address being a first value, the LUT is created using the grayscale value of that gamma data address, and in response to the gamma data value of a gamma data address being a second value, the LUT is not created using the grayscale value of that gamma data address.
