摘要： Input video signals characterized by a source electro-optical transfer function (EOTF) are to be blended and displayed on a target display with a target EOTF which is different than the source EOTF. Given an input set of blending parameters, an output set of blending parameters is generated as follows. The input blending parameters are scaled by video signal metrics computed in the target EOTF to generate scaled blending parameters. The scaled blended parameters are mapped back to the source EOTF space to generate mapped blending parameters. Finally the mapped blending parameters are normalized to generate the output blending parameters. An output blended image is generating by blending the input video signals using the output blending parameters. Examples of generating the video signal metrics are also provided.

摘要： Even when an OSD video signal is superimposed on a video signal, deterioration in the frequency characteristic or in gradation of the video or OSD video signal superimposed on it is minimized. A graphic image is represented by a video signal that provides color information and degree of transparency information on a pixel basis. The video processor includes: a filtering section, which receives and converts a 4:2:0 format video signal representing the video into a 4:2:2 or 4:4:4 format video signal; a decision section, which determines, by reference to the transparency information, whether the graphic image be superimposed on the video; a synthesizing section, which superimposes a color difference signal representing the graphic image on that of the video signal converted by the filtering section; and a scaling section for performing scaling on the synthetic color difference signal. Depending on the decision result, the filtering and scaling sections change between a mode of processing to retain pixel data and location information of the color difference signal of the 4:2:0 format video signal and another mode of processing to retain not to retain the pixel data and location information.

摘要： A television receiver, which is an image display device of the present invention, includes an EPG/OSD/reservation processing section (24) including a CLUT application section (1) and a CLUT update section (2). The CLUT application section (1) causes an OSD area to be divided into a plurality of division areas, and CLUTs are applied to the respective plurality of division areas. The CLUT update section (2) causes a CLUT, which has been applied, to be changed to another CLUT so as to realize palette animation in one of the division areas. This makes it possible to provide an image display device and a method for displaying an on-screen display image, both of which enable an OSD expression with high resolution and high memory efficiency, in which OSD expression palette animation can be realized at a high speed regardless of the number of colors used in original image data of the OSD.

摘要： Display systems and image processing methods process pre-subpixel rendered images embedded in input color image data. The display systems include a pre-subpixel rendered (P-SPR) image detector that detects locations of a marking code that marks the portion of the input data that has been pre-subpixel rendered and which is ready for direct display. Several display system embodiments comprise first and second image data paths; the input data that requires subpixel rendering proceeds along the first path while the P-SPR image data proceeds along the second path. Another display system embodiment processes the combined input and P-SPR data along a single data path. Techniques for marking and detecting P-SPR image data using two distinct marking codes are presented in the context of the subpixel layout of the display. Techniques for using P-SPR data to display high-quality graphical symbols (e.g., font glyphs) are suitable for small, low-cost display devices.

摘要： A process and circuit for blending a foreground image (B) with a background image (A) , said foreground and background images being arranged in pixels and having color representations (R, G, B) . The foreground foreground image (A) has a transparency parameter (T(x,y)) in accordance with a so-called alpha plane representative of the transparency profile to apply to the foreground image.
The process involves the steps of:
- applying a dithering method on said alpha plane in order to convert said transparency parameter (T) into a one-bit transparency parameter (T');
- use said one-bit transparency parameter (T') for controlling a multiplexing unit having two inputs respectively receiving the foreground image (A) and the background image (B).
In one embodiment, the one-bit transparency parameter T' into the two extreme values of a range of continuous values, for instance coded on 8 bits.
The process then applies a four-pixel interpolation method to the foreground image (A) for the purpose of creating a five level transparency parameter in the blending process, and then uses the five level transparency parameter for controlling a multiplexing circuit for the purpose of achieving blending of the foreground image with the background image.

摘要： In a method of mixing a graphics signal and a video signal in a ratio alpha:(1-alpha), where the graphics signal is obtained by addressing a color lookup table (CLUT) in which color values (R, G, B) are stored, the number of color values stored for each mixing ratio depends on the mixing ratio so as to obtain an optimum filling of the color lookup table.

摘要： Continuous wave signals synchronized with first chrominance subcarrier signals are generated (by means of a chrominance subcarrier extracting circuit (2), a phase error detecting circuit (3), an A/D conversion circuit (4), and a digital oscillation circuit (5)) from the analog video signals including the first chrominance subcarrier signals supplied to an input terminal (1). Digital video signals including chrominance components supplied to an input terminal (7) is converted into a composite video signal including chrominance signals (by means of a digital video signal converting circuit (6)). In this case, the chrominance components are converted into the chrominance signals by using the continuous wave signals, and the phase of the first chrominance subcarrier signals of the analog video signals is synchronized with that of the second chrominance subcarrier signals of the chrominance signals of the composite video signal produced from the digital video signals. Thus, the phase of the chrominance signals of the analog video signals can be synchronized with that of the chrominance signals of the composite video signal produced from the digital video signal, with, for example, a simple circuit constitution, and a picture drawn by the digital video signals can be easily combined with another picture drawn by the analog video signals.
