Abstract
An image display device includes: a display partthat displays a video image based on an input signal; a video image adjusting partfor adjusting a parameter of the video image; and a region selecting partfor selecting a region in the video image, with respect to which an adjustment of the parameter is performed. The display part is capable of composing, based a video image in the selected region, a first video imagebefore the adjustment of the parameter and a second video imageto be used for the adjustment, displaying the first video image and the second video image above and below each other or side by side, and displaying either of the first video image and the second video image upside down or in a mirror-reversed manner. By operating the chroma adjusting bar, the hue adjusting bar, the luminance adjusting barof the video image adjusting part(image adjustment parameter display screen), the second video imageis varied, and when a desired video image is obtained, the image is fixed, so that contents of the adjustment are reflected throughout the whole video image. Since the first video image or the second video image is displayed upside down or in a mirror-reversed manner, an influence of the human visual characteristics is eliminated, thereby enabling a precise image quality adjustment.
