Abstract
A display device performs the fractional part of gamma translation by using a logarithm lookup table. The logarithm of an image data value is found in a look-up table. The retrieved result is multiplied by the fractional portion of the power, and a search in the look up table for this product produces an index related to the desired result. In another embodiment, rather than a search of the first look up table, a second inverse logarithm look up table is used to produce the desired result by looking up the exponentiation of the product.
