Abstract: The present invention is aimed at appropriately suppressing display failure such as a tailing phenomenon and the like in a normally white type liquid crystal panel. A driver (3) supplies a drive voltage in conformity with an image signal received by an image signal processing circuit (1), to a liquid crystal panel (4). A histogram detector (5) detects a histogram representing the relationship between the signal level of the image signal received by the image signal processing circuit (1) and the number of pixels. A CPU (6) calculates, based on the histogram detected by the histogram detector (5), a first proportion of the number of pixels (on the white side) whose signal level is equal to or greater than a first defined value, to the total number of pixels of the histogram and a second proportion of the number of pixels (on the black side) whose signal level is equal to or smaller than a second defined value that is smaller than the first defined value, to the total number of pixels of the histogram.

Abstract: An image display apparatus includes: a panel (16a) that includes a plurality of picture elements that change transmittance of light according to picture levels; a detection unit (12) that detects, in one-image portions of the panel (16a), picture levels for each of the plurality of picture elements from picture signals that indicate the picture levels of each picture element; and a processor (18) that, based on the picture levels of one-image portions that were detected by the detection unit (12), adjusts the transmittance of light of the plurality of picture elements such that the image realized by the picture signal is brighter when a value that corresponds to brightness is greater than a predetermined threshold value.

Abstract: A first area and a second are formed in an image projected by a projector. A standard image plate is placed in a surface on which an image for the first area is projected. A standard image has been drawn on a standard image plate and is displayed in correct colors when white light is projected on the standard image plate. The projector projects white light as the image for the first area. An image for the second area is projected on a projecting surface. A user operates an operating section so that the image in the second area is closer to the standard image. A color correcting section corrects the colors of the image in the second area on the basis of information inputted to the operating section.

Abstract: In a method of improving quality of color images displayed on or produced from a color image device, a user is made to select a color or an object area of an object of user's interest and color correction is conducted using the selected item as a central color of correction to thereby flexibly achieve color correction. The image color correcting device 1 conducts color correction for an input image 2 and supplying an output image to an image display section 3 and includes object selecting means 10 for selecting an object item or an object color as a color correction object from the output image of the image display section 3 and a color correction processing section 11 for calculating a central color of an object item or an object color thus selected and setting the central color as a central color of correction and correcting the central color to thereby correct the output image into a desired color.
