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 image processing apparatus prevents the inappropriate application of error diffusion and adaptively applies palette conversion functions according to the properties of the source. A processing subsystem performs various processing with respect to an original video source. A palette converter converts the palette bit depth, having modifiable palette conversion functions for creating the illusion of expressing the pre-conversion palette tones in the post-conversion image. A controller turns on the palette converter, turns off the palette converter, or modifies the palette conversion functions thereof, in accordance with at least original source information and system-wide settings information.

摘要： An optical pulse evaluation device and an in-service optical pulse evaluation device is disclosed which are capable of characteristics evaluation of an optical pulse itself or a sample launched therein in a relatively high bit-rate region. The optical pulse evaluation device evaluates a pulse waveform expressing an optical intensity of the optical pulse, an instantaneous frequency of the optical pulse, or a modulated light prepared by modulating the optical pulse in a light source end. The optical pulse evaluation device also observes a waveform change after a known optical pulse is passed through a device such as an optical fiber to evaluate a waveform deterioration or a compensation behavior caused by the device. The in-service optical pulse evaluation device is capable of measuring a wavelength dispersion in an optical communication.
