Abstract:
An object is to obtain a visibility-improved video while more favorably maintaining a color rendering property in a video display device. To achieve the object, a video input unit, a video correcting unit that performs video correction on a video input by the video input unit, and a video display unit that displays the video corrected by the video correcting unit are included, and the video correcting unit is configured to perform local luminance correction on the video input by the video input unit, acquire a correction intensity for each part of the local luminance correction, and perform local saturation correction based on the correction intensity.
