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： 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.

摘要： An image processing apparatus includes a CPU which executes a program read from an external storage unit, and a video processor. In the video processor, color data of moving picture characters and color data of still picture characters are respectively outputted from a moving picture data generating circuit and a still picture data generating circuit. Both the color data are applied to a main/subsidiary data selection circuit which outputs the color data as main image data and subsidiary image data. An arithmetic circuit executes an arithmetic operation to obtain a mean value of both the color data. A video signal producing circuit converts the mean value of the color data from the arithmetic circuit into a video signal which is then applied to a display.

摘要： A mix effects based switcher architecture provides for processing of video signals with associated key signals throughout, the mix effects (M/E) (22) banks within the switcher outputting both a composited video signal and a composited key signal for use by subsequent M/E banks. The outputs of the M/E banks may be combined together before being input to an output M/E bank (26). The output M/E bank provides a layered video signal with associated composited key signal at the output of the switcher.

摘要： First and second signals, with given bias levels are applied to respective inputs (out 1, out 2) of a non-additive mixer (NAM) circuit (100) through respective switches (SW1,SW2) which can be in a low-cost CMOS switch (30) to provide a cost effective switch for television signals. Each input of the NAM circuit is biased at a reference level (through R1,R3) in the absence of applied signal to it. The input receiving signal plus bias is enabled thereby to convey its respective signal to the output (40) of the NAM circuit (100), and the input receiving the reference bias level is prevented from conveying its respective signal to the output (40) of the NAM circuit (100).

摘要： Le système comprend des moyens de mélange (11) ayant deux moyens d'amplification à gain variable (13 1 , 13 2 ) recevant deux signaux d'image (I 1 , I 2 ) ayant une amplitude crête-à-crête prédéterminée et des moyens d'addition (14) pour mélanger des signaux sortant des moyens d'amplification en un signal résultant (R). Il est caractérisé par des moyens (12) pour établir un unique signal de commande de gain (aa) à partir d'une combinaison linéaire de deux signaux (SC 1 , SC 2 ) issus respectivement des deux signaux d'image (I 1 , I 2 ) afin que le signal résultant (R) ait ladite amplitude crête-à-crête. Le signal de commande (aa) est appliqué à travers des moyens d'inversion analogiques (17) et directement à des entrées de commande de gain (16 1 , 16 2 ) des moyens d'amplification à gain variable (13 1 , 13 2 ) respectivement.
