Abstract
A module processes image data to provide gray level signals to be used for displaying an image. The module may include a scale value control member for determining a first scale value. The module may further include a brightness control member for determining a controlled brightness value using a requested brightness value, a brightness control parameter, and a baseline brightness value. The module may further include a modification member for determining a modified scale value using the first scale value and the controlled brightness value. The module may further include a scaler for generating the gray level signals using the image data and at least one of the modified scale value and a damped scale value, the damped scale value being determined using the modified scale value. The module may further include hardware circuitry for implementing at least one of the aforementioned components.
