摘要： 2.1. Bei Aufnahmen mit Videokameras oder bei nachträglicher Bearbeitung von Videofilmen mit Videorecordern will man dem Anwender auch Möglichkeiten geben, den Bildinhalt zu verändern, d.h. Bildeffekte zu erzielen. Zu den am meisten verwendeten Bildeffekten gehört das Ein- und Ausblenden von Bildern oder Szenen bzw. das Überblenden von einer Szene zur anderen, oder die Erzeugung von Farbeffekten. Aufgabe der Erfindung ist es eine Anordnung anzugeben, welche die obengenannten Anforderungen erfüllt und zudem einfach im Aufbau ist, so daß ihr Einsatz nicht nur auf Profigeräte beschränkt ist.
2.2 Dies wird erfindungsgemäß dadurch erreicht, daß ein Leuchtdichtesignal bzw. ein Farbsignal, welches in digitalisierter Form vorliegt, in einem Komparator mit einem Grauwert bzw. einem Farbsättigungswert verglichen wird, und in Abhängigkeit vom gewünschten Bildeffekt eines der beiden Signale durchgesteuert wird. Zur Erzielung von Übergängen ist die Vorgabe des Grauwertes bzw. des Farbsättigungswertes mit einem Zähler realisiert, dessen Zählrichtung und Zählgeschwindigkeit vorgegeben werden kann.

摘要翻译： 2.1使用摄像机进行录像时或在使用录像机进行视频胶片的后续处理时，也可以给用户更换图像内容，也就是实现画面效果。最经常使用的图形效果包括图像或场景的衰落和淡出，以及从一个场景到另一个场景的交叉衰落，或者产生颜色效果。本发明的目的是指定满足上述要求的装置，另外设计简单，不仅限于专业装置。 2.2根据本发明，这是通过以下事实实现的：将比较器中以亮度信号或以数字形式存在的色度信号分别与灰度值或色彩饱和度值进行比较，并且两个信号之一根据所需的画面效果切换。为了实现转换，灰度值或色饱和度值通过计数器预先确定，计数方向和计数速度可以被预先确定。 2.3视频设备。

摘要： A method and apparatus are disclosed for representing and displaying the true (actual) color of an image in an index color system. The user specifies the number of color levels necessary to represent the range of displayable colors, and specifies the color (the red, green, blue primary color values) desired for an image. From the specified number, the apparatus calculates RGB (red, green, blue) color values, and stores them in memory in a manner suitable for referencing by an index type address. From the specified color, the apparatus calculates an index suitable for referencing the desired RGB color values from the stored color values. The apparatus comprises a keyboard and a port to a host computer for inputting index color data and true color data, a processing means coupled to the keyboard and/or host computer for producing index-type data from true color data, a memory means for storing the input data and data produced by the processing means, and a display means for displaying stored data.

摘要： A television graphics system comprises an analog-to-digital converter for digitizing an encoded analog input video signal and generating an encoded digital signal representative of the magnitude of the encoded analog input video signal at a succession of sampling points, a memory device, and a device for writing the encoded digital signal into the memory device. The graphics system also comprises a computer connected to read the encoded digital signal from the memory device, and an arithmetic unit for decoding the encoded digital signal so as to provide decoded digital signals representative of the magnitudes of the luminance and chrominance components of the analog input video signal. The computer is used to modify at least one of the decoded digital signals, and the arithmetic unit encodes the modified digital signal to generate a modified encoded digital signal representative of a modified form of the picture. The modified encoded digital signal is then written into into the memory device.

摘要： A method and apparatus is disclosed which provides for the placement of a border video signal around a selected object in a video image. A video image of the selected object is first inserted into a video image of a selected border video signal in a video mixing process by use of a key signal defining the selected object. The key signal is further processed to transform the step transitions associated therewith between the zero and full insert states into non-step transitions. The transformed key signal is thereafter used to control a subsequent mixing of the resulting image of the selected object inserted into the video image of the border video signal with a background image to produce a composite video image.

摘要： An arrangement for rotating television pictures comprises a frame store (10) into which a rotated input picture is written under the control of a write address generator (12) which is in turn controlled by a rotation control and timing generator (5). A video input signal is applied at input (1) and fed to a splitting circuit (4) which produces streams of even and odd numbered samples, both at the sampling rate. These streams of samples are fed to an interpolator (8) where they are used to generate samples to be written into the store (10).
The store (10) is split into four areas which are arranged to hold respectively field 1 odd samples, field 1 even samples, field 2 odd samples, and field 2 even samples. The write address generator (12) is controlled so that samples from field 1 of the input signal are fed only into the areas of the store read by the read address generator (14) during field 1 of the output signal and samples from field 2 of the input signal are fed only into the areas of the store read by the read address generator (14) during field 2 of the output signal.

摘要： An object is to accurately provide the user with color fidelity information irrespective of difference in the time of day when or in the location where a commercial product is photographed and prevent mismatching of the user's selection of the commercial product. A color fidelity environment correction system 1 includes a camera 2 and a computer 5 that is connectable with the camera 2, a tablet terminal 3 and a display device 4 and is configured to include a CPU, a ROM, a RAM, a hard disk drive and a bus line. A red vehicle 6 is photographed with the camera 2 (RC-500) in a plant or the like, and XYZ color fidelity images are recorded in a storage unit 51 of the computer 5. Another blue vehicle 7 is photographed with the tablet terminal 3 in the open air, and an RGB color image is stored in a storage unit 52. An RGB color image of the red color vehicle is created with replacement of the blue color of the RGB color image of the vehicle 7 with red color of the 3-band visual sensitivity images S1i, S2i and S3i of the vehicle 6 and is displayed on the display device 4 or is displayed with the RGB color image of the blue vehicle 7 in a comparative manner.
