Semiconductor device including correction parameter generator and method of generating correction parameters

摘要

A semiconductor device includes an address generator and an output unit. The address generator is configured to output a plurality of addresses in response to a first number of most significant bits of a current pixel value including a first selection bit and a second number of most significant bits of a previous pixel value including a second selection bit. The output unit is configured to determine correction parameters which respectively correspond to the plurality of addresses, in response to the plurality of addresses, to select an index pattern from a plurality of index patterns in response to the first selection bit and the second selection bit, and to arrange the determined correction parameters into the selected index pattern to output arranged correction parameters. The index pattern is a pattern that can be generated according to positions of the determined correction parameters in a look-up table including the plurality of indexes.
