Patent ID: 7245308

Claim:
A display control device for outputting an output image signal, said display control device comprising: a characteristic value-calculating unit for calculating a characteristic value based on an input image signal; and a conversion characteristic-calculating unit for determining at least one conversion characteristic adaptively with respect to the input image signal based on the characteristic value, wherein said conversion characteristic-calculating unit is further for determining the at least one conversion characteristic such that, when an abscissa axis represents the input image signal and an ordinate axis represents the output image signal, and a range from an origin of the axes to a full scale point along the abscissa axis is divided into a low level region, which is close to the origin, a high level region, which is close to the full scale point, and a middle level region, which is positioned between the low level region and the high level region, an average slope of the output image signal in the middle level region is greater than any one of average slopes of the output image signal in the low and high level regions.
