摘要： An image whose visibility has been more suitably improved is obtained. The device includes an image input unit which inputs an image, an image processing unit which performs Retinex processing with respect to the input image input by the image input unit and performs image signal generation to generate a new image signal based on information concerning a color of the input image and information of an absolute value or Y-value of a color space vector of the image signal having undergone the Retinex processing, and a display unit which displays an image based on the image signal having undergone image processing by the image processing unit.

摘要： Even when a watching position or a watching direction of a viewer for a video changes, video display with favorable visibility is obtained. A video display apparatus that receives an input of a video input signal and that displays a video based on the video input signal includes a viewer detection unit that detects a positional relation between a screen on which the video is displayed and a viewer who watches the video and that generates viewer position information including the detection result, an image processing unit that executes image correction processing for a correction region which is such a partial region of an image based on the video input signal as being set in correspondence with viewer position information, and a video display unit that displays, on the screen, a video based on a corrected video signal having been subjected to the image correction processing.

摘要： A projector is provided with: an image processing unit that image-processes inputted image signals; an image display element, to which the image signals image-processed by means of the image processing unit are inputted, and which generates an optical image; and a projection optical system that projects, to a projection surface, the optical image generated by means of the image display element. The image processing unit has an image correction unit for reducing blurring of an image to be projected by means of the projection optical system, and the image correction unit changes the black luminance level of the image signals.
