摘要： 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.

摘要翻译：在显示面板上显示OSD屏幕等静止图像时，适当防止老化现象。当以叠加的方式在视频屏幕上显示菜单屏幕时，在菜单背景区域上删除左眼视频和右眼视频中的至少一个中的菜单短语。在菜单背景区域和菜单短语之间的边界中的静止像素之间的亮度差保持较大的时间段减少，从而可以防止老化现象的发生。但是，菜单背景区域不会被删除而不断显示，从而不会出现屏幕闪烁。

摘要： 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.

摘要： An optical disk apparatus can reliably detect the target recording layer of an optical disk having two recording layers. The optical disk apparatus is adapted to recording information on and reproducing information from an optical disk formed by sequentially laying a first recording layer, a second recording layer and a cover layer. The focal point of the light beam is moved closer to the optical disk from the side of the cover layer and the focal point of the light beam is determined to be coming close to the recording layer when the signal level of the focus error signal falls below a positive focus error threshold value after rising above the latter or rises above the negative focus error threshold value after falling below the latter. Then, the focal point of the light beam is kept on moving toward the optical disk after the detection of the recording layer and the recording layer that is detected last is determined to be the first recording layer when the recording layer is not re-detected within a re-detection period.

摘要： A code conversion method that may be used for uniquely converting n-bit codes inclusive of those capable of being converted into first and second m-bit data, where n>m. With the present method, a conversion table may be reduced for reducing the size of the conversion circuit. At a step S1, a status bit specifying whether or not a n-bit code next following the n-bit code being converted is a first pre-set codestring. At a step S2, the n-bit codes are split into a first code made up of upper k bits, where 0
