Abstract

Provided herein is an image display device, a driving method thereof, an image display program, and a grayscale converter, wherein the image display device includes: a display section on which an image is displayed by using pixels arranged in a two-dimensional matrix; a gradation conversion section that performs gradation conversion processing by using an error diffusion method, wherein the gradation conversion section divides an area where pixels are set into virtual partitions, and executes gradation conversion processing on pixels within the virtual partitions only within the virtual partitions When the error diffusion is performed, gradation conversion is performed on the image displayed on the display section.

Description

technical field [0001] The present invention relates to an image display device for displaying an image on a display portion such as a liquid crystal display panel. Furthermore, the present invention relates to a driving method of an image display device, an image display program executed by the image display device, and a gray scale converter included in the image display device. Background technique [0002] Liquid crystal display panels suitable for monochrome display or color display, electroluminescence electroluminescence using inorganic materials or organic materials are used in display sections of portable electronic devices such as mobile phones or personal digital assistants, personal computers, and television receivers. Luminescence display panels, plasma display panels, etc. [0003] When the gradation display capability of the pixels of the display portion is low, in other words, when the number of gradations in the pixels is small, contour-like outlines are ge...
