Image display device and image display method

Abstract

An image display device is provided, with less color breaking in the field sequential method. A color component image with a relatively high luminance level is extracted as a fundamental image from an input image. A differential image is obtained by subtracting color component of the fundamental image from an input image, and is decomposed into a plurality of color components. The differential image for each color component is divided into two. The fundamental image is displayed at a middle timing of a frame period. The half-divided differential images are displayed at timings before and after the middle timing for the fundamental image so that the half-divided differential image with higher luminance level with consideration for visibility characteristic is displayed at a timing closer to the middle timing for the fundamental image.

Description

technical field [0001] The present invention relates to an image display device and an image display method for performing color image display by a Field Sequential Method (Field Sequential Method). Background technique [0002] Color image display methods are roughly classified into two methods depending on the color additive mixing method. The first method is a color addition method based on the principle of spatial color mixing. More specifically, the individual sub-pixels of the three primary colors of light R (red), G (green), and B (blue) are finely arranged in a plane, so that the spatial resolution of the human eye cannot distinguish the individual color lights, so that in Colors are mixed on one screen to obtain a color image. The first method applies to most currently marketed display types such as Braun tube type, PDP (plasma display) type and liquid crystal display type. When the first method is used to construct a display device of a type in which light (back...

Problems solved by technology

However, the RGB images sequentially displayed in a time manner cannot be well mixed due to the limitation of the optic nerve including the eyeball and the complex factors of the image recognition perception of the human brain

As a result, when an image with low color purity, such as a white image, is displayed, or when follow-up observation is performed on a moving display of a display object within the screen, each primary color image is sometimes observed as a residual image or the like, causing trouble to the observer. Extremely uncomfortable color break-up display phenomenon
