摘要： An image display device includes region of interest extraction unit, parallax image generation unit and 3D image display unit. Region of interest extraction unit generates depth image signal by depth image conversion employing depth threshold, depth image signal including information on distance in three-dimensional space between viewpoint and each pixel of two-dimensional image including region of interest desired to be noted by observer, depth image conversion being such that depth value indicating distance between viewpoint and each pixel of two-dimensional image is converted to depth value for 2D display when depth value is equal to or larger than depth threshold. Parallax image generation unit generates both-eye parallax image having parallax in region of interest alone, from two-dimensional image and image obtained by conversion of region of interest image representing region of interest at each of both-eye viewpoints, based on two-dimensional image and depth image signal. 3D image display unit displays both eye parallax image.

摘要： There is provided an image display device capable of obtaining a renewed screen giving normal feelings by simple LUT (Look Up Table) adjustment even at a time of displaying with multiple gray levels. A screen of the electronic paper section making up the display device is renewed by driving for a period of time corresponding to a plurality of frames according to input gray level data of a renewed screen. The renewed screen is displayed with a coarse gray level during a first displaying period in a renewing period corresponding to a plurality of frames at an output voltage specified by a high-order bit of its gray level data and, thereafter, is displayed with a fine gray level during a second displaying period in the renewing period at an output voltage specified by a low-order bit of its gray level data.
