  • Patent number: 11205402
    Abstract: In an information display apparatus and method, images of a plurality of planar objects disposed in a virtual space are generated based on texture information of each of the objects, viewpoint information, and surrounding environment information, and combined to generate a display image. The virtual space is a simulation of a space in which a display device is placed, the objects are disposed in parallel with a plane in the virtual space corresponding to a display screen of the display device. The texture can be expressed with a small quantity of data and a small memory size, and an image which has a good reality can be displayed with a good responsiveness to the motion of the observer.

  • Patent number: 9167193
    Abstract: A display device is provided that controls, considering affection due to a watcher's age and his viewing distance as human-visual characteristics, a display-screen brightness level at which the watcher does not feel glare. The display-screen brightness is most suitably set by simple calculation using relationships among watcher's ages, display sizes, glare levels, and screen-illuminance levels, etc. obtained by a subjective-assessment experiment. According to this display device, considering watcher's various conditions such as the age, the visual acuity, and the viewing distance, even if the watcher watches the display for a relatively long time, the watcher does not feel tiredness; thus, comfortable watching can be achieved.

  • Patent number: 8558772
    Abstract: An image processing apparatus is obtained which is capable of performing gray-level correction while maintaining real-time property and accurately recognizing the feature of content obtained from an image signal. A luminance information detecting block detects a luminance information value about individual pixels from a luminance signal contained in an image signal. On the basis of the luminance information value, a content feature detecting block determines the feature of one frame of the video content, and obtains a content feature judge information value. On the basis of the content feature judge information value, a multiple content feature detecting block detects the feature of multiple frames of the video content, and outputs a multiple content feature judge information value to an image quality adjustment control block in an image quality adjusting block.
