Abstract
The present invention relates to a look up table method for reducing the use of memory and more particularly to a condition while the input value has higher bits than the output value. This look up table method comprises: data storing that storing the input data into memory corresponding with output data with reference to the address of output data; and data searching including reading an input data, finding a closest address to the input data, and outputting the closest address. In this present invented look-up table method, the relation curve between the output value and corresponded input value is a monotonic curve, such as a γ curve.
