Title: IMAGE SIGNAL PROCESSING METHOD, IMAGE SIGNAL PROCESSING DEVICE AND IMAGE SIGNAL PROCESSING PROGRAM
Abstract:
This image signal processing method involves: a partitioning step which partitions a video signal into a first signal which includes a contrast component signal, and a second signal which, of the component signals in the video signal, includes component signals other than the component signal included in the first signal; a brightness adjustment step which, of the component signals partitioned in the partitioning step, performs brightness adjustment processing on the second signal; and a synthesis step which synthesizes the first signal partitioned in the partitioning step and the second signal after brightness adjustment in the brightness adjustment step.
