IMAGE SIGNAL PROCESSING CIRCUIT AND DISPLAY DEVICE INCLUDING THE SAME |
| 摘要 |
A signal processing circuit includes an input gamma adjuster configured to adjust gamma characteristics of an image signal and to output a gamma adjustment image signal, an image signal processor configured to generate a scaling signal corresponding to image characteristics of the gamma adjustment image signal and to convert the gamma adjustment image signal into an intermediate data signal in response to the scaling signal, and an output gamma adjuster configured to convert the intermediate data signal into a data signal on a basis of a first lookup table corresponding to a first gamma curve, a second lookup table corresponding to a second gamma curve, and the scaling signal. |
