Abstract: To make it easy to select an optimal viewing environment depending on content and preference of each person when viewing an image with a head-mounted display or a large-screen display device. Evaluation values of respective elements of a visual effect with respect to viewing environments and image configurations are determined in advance. For example, when an observer tries to start image viewing, a viewing environment that is most likely to provide a desired visual effect is automatically extracted on the basis of the evaluation value determined in advance with respect to the viewing environment and the image configuration and parameters of that viewing environment are displayed in an easily understandable manner as GUIs. Further, the evaluation values of the elements of the viewing effect in the selected viewing environment are also displayed.

Abstract: To appropriately prevent a burn-in phenomenon when a still image such as an OSD screen is displayed on a display panel. When a menu screen is displayed on a video screen in a superimposed manner, a menu phrase in at least one of a left-eye video and a right-eye video is deleted on a menu background area. A time period in which a brightness difference between still pixels in a boundary between a menu background area and a menu phrase remains large is reduced, and thus the occurrence of the burn-in phenomenon can be prevented. However, the menu background area is constantly displayed without being deleted, so that screen flickering does not occur.

Abstract: To appropriately process an image following a motion of a head of a user. An image display system 100 includes an attachment position error measuring function which measures deviation between reference axes of a head action tracking device 200 (x, y, z) and reference axes of the user (xw, yw, zw), i.e., an attachment position error of the head act ion tracking device 200, and an attachment position error absorbing function which corrects, based on the attachment position error, posture information about a posture of the head of the user detected by the head action tracking device 200. An image drawing device 300 therefore renders, based on precise posture information, an image accurately following a motion of the head of the user.

Abstract: An image display device includes an image input unit which inputs an image; a display unit which displays the image; and an image conversion unit which converts an input image so that a display image on the display unit is viewed as an image which is displayed in a predetermined format.

Abstract: Provided is a head mounted display including a displaying unit to display an image, an image signal processing unit to process an image signal, a display control unit to perform an image quality adjustment of the image signal processed by the image signal processing unit, and to control a display in the displaying unit, a mounting sensor to detect whether an observer has mounted the apparatus, and a control unit to issue an instruction for the image quality adjustment of the image signal in the display control unit, in response to a detection result by the mounting sensor.

Abstract: A first-person viewpoint image captured by a camera mounted on a radio-controlled model is displayed on a head mount display and is enjoyed. When a whole-sky image captured by a camera unit 605 mounted on a model apparatus 120 is reproduced and displayed with a head mount display 110, a CPU 601 moves the display field so as to offset the motion of the head of a user detected by a posture/location detecting unit 604. In this manner, an image that follows the motion of the head of the user is displayed. Meanwhile, on the side of the head mount display 110, a combined image generated by superimposing an AR image as virtual image information on the actual image in the display field is displayed.

Abstract: To appropriately prevent a burn-in phenomenon when a still image such as an OSD screen is displayed on a display panel. When a menu screen is displayed on a video screen in a superimposed manner, a menu phrase in at least one of a left-eye video and a right-eye video is deleted on a menu background area. A time period in which a brightness difference between still pixels in a boundary between a menu background area and a menu phrase remains large is reduced, and thus the occurrence of the burn-in phenomenon can be prevented. However, the menu background area is constantly displayed without being deleted, so that screen flickering does not occur.

Abstract: To appropriately prevent the occurrence of a burn-in phenomenon during a display of a video in which an OSD screen is superimposed on a video screen. By appropriately moving the position for displaying an OSD screen when the OSD screen is displayed on a video screen in a superimposed manner, a burn-in phenomenon is prevented from occurring in a menu background area of the OSD screen or a boundary portion between a menu background area and a menu phrase. For example, each time the OSD screen is displayed, the OSD screen is moved by one pixel and then displayed. Movement of the display position of the OSD screen is implemented by an instruction from an OSD display position control unit 215.
