摘要：A gamma correction circuit has a data group generator which stores first to n-thgamma correction tables, receives first to n-th gains, and adjusts a level of the inputsignal using the first to n-th gamma correction tables and the first to n-th gains, therebyproducing a gamma-corrected data group including first to n-th gamma-corrected data.

The circuit also has a gamma characteristic controller which loads the first to n-th gainsinto the data group generator, a signal level discriminator which outputs a discriminationsignal based on the level of the input signal, the first to n-th gamma correction tables,and the first to n-th gains, and an output selector which selects from among the first ton-th gamma-corrected data on the basis of a value of the discrimination signal, therebyproducing the gamma-corrected output signal.
