Abstract
A display controller includes a local contrast enhancement circuit that includes a plurality of scale circuits. Each scale circuit includes a block separation circuit configured to divide input display data into sub blocks, a calculation circuit configured to calculate a feature value that characterizes each of the sub blocks, and a storage device configured to store the feature value. The number and size of the sub blocks differ among the scale circuits.
