The function of any powers using a logarithmic look-up table

摘要

By using the logarithm lookup table, display device, to perform the part of the decimal point of the gamma conversion. Logarithm of image data values ​​are obtained in a look-up table (104) within. The results, as well as multiplied by the fractional portion of the exponent, the search look-up table for the product of the (104) within creates an index relating to a desired result. In other embodiments, the antilog look-up table and the second (114), are used to create the desired result by searching the index of the product rather than the (112) the first lookup table .
