Abstract
An apparatus for overdrive computation and method therefor. The overdrive computation apparatus is used for generating a desired overdrive gray-level value and includes first and second addition/subtraction devices, a priority encoder, and a computation device. The first addition/subtraction device outputs a difference value indicating difference between a first overdrive gray-level value ODand a second overdrive gray-level value OD. The priority encoder determines a decision signal according to the difference value. The computation device receives first gray-level data, determines a first computation according to the decision signal, and performs the first computation on the first gray-level data to output operated gray-level data. The first gray-level data indicates a value lying between the ith first gray-level index value X(i) and the (i+1)th first gray-level index value X(i+1). The second addition/subtraction device receives the operated gray-level data and the first overdrive gray-level value ODto produce the desired overdrive gray-level value.
