摘要： This invention relates to a system and method for placing event related information into a video broadcasting so that the added information does not interfere with or obscure the primary action of interest in the broadcast. The disclosed information could be implemented by using instructions from an event information gathering system to trigger the display of one of an appropriate set of pre-rendered animations in the broadcast video via a well known live video insertion system (48). The disclosed invention envisages the animation sequence having at least two parts (FIG. 4), namely a core or base sequence (34) which is always used, and a mid or a variable sequence (56, 58, 60) which is changed according to the actual data that needs to be displayed. The live video insertion system data (48) and processing may be used to perform occlusion, and/or tracking to either make the event information display look as if it is part of the scene, or merely to occlude the display when event action would otherwise be obscured, or to turn off or reposition, or resize the display when event action otherwise be obscured.

摘要： Creating a transition between a first sequence of video frames and a second sequence of video frames. The method includes storing a table of values that express a non-linear response to certain levels of light, generating a transition between the sequences, and adjusting the intensity at which material of the first sequence is displayed relative to the intensity at which material of the second sequence is displayed within the transition, based on the values stored in the step of storing.

摘要： Alpha values associated with video mixing operations are sent to a memory on a low pin count bus. The memory is accessible to a video mixer, which retrieves the alpha values to perform a mixing operation. The alpha values for a field are sent to the memory during the field time for a previous field rather than during the vertical blanking interval. The alpha values may be compressed prior to transmission.

摘要： A camera system switches electronically between infrared radiation sensing and visible light sensing depending on ambient conditions, to optimize visible picture quality for surveillance. An electronic CCD camera has an optical bandpass filter having a stop band between the infrared radiation spectrum and the visible light spectrum to provide high quality visible light images when not in the infrared mode and high quality mono infrared images when not in visible light mode. A control circuit compares the camera signal with a photocell signal and controls the camera's sensing mode and an if illuminator's operation in accordance with the ambient conditions.

摘要： A fade circuit adjusts the luma as well as one or more chroma components of a main video so that the fade ins and fade outs of the main video do not change the color of an on-screen display image, such as the volume bar. In one embodiment, luma component (Y) is adjusted by subtracting a fade factor from the luma component to form a faded luma component. At the same time, one or more chroma components (Cb and Cr) are scaled by (1) subtracting a predetermined value from the chroma component to form a resultant, (2) multiplying the resultant with a scale factor to form a product, and (3) adding the predetermined value to the product to form a faded chroma component.

摘要： A media pipeline with two channels processes sequences of digital still images. A blender is provided so as to enable simple effects on these two streams of video data such as dissolves, wipes and chroma keys. Complex arbitrary three-dimensional effects and other effects may also be provided using an external interface. Thus, a system for processing sequences of digital still images to provide real-time digital video effects includes first and second channels for communicating first and second sequences of digital still images at a rate for simulating video. A controller directs still images to one of the first and second channels. A blender, having a first input connected to the first channel, a second input connected to the second channel, and an output, provides a combination of the first and second sequences of digital still images at a rate for simulating video.

摘要： A video signal mixer with a parabolic signal mixing function, especially useful in scene-by-scene color correction systems and “blue screen” video masking applications. The mixer effects mixing two independent signal sources while smoothly controlling the rate of change during mixing. An input stage receives a first video signal and a second video signal. The mixing circuit mixes the first video signal with the second video signal based on a predetermined parabolic function. An aperture signal circuit in the mixer allows a degree of operator control over the parabolic function. An output stage provides a parabolized output signal. The output signal, which comprises the mixture of the first video signal and the second video signal, eliminates discontinuities in regions of the signal which would otherwise produce discontinuities in prior art types of video signal mixers.

摘要： A method for the digital manipulation of a video image, in which an object is located and replaced by another object. To account for ambient lighting effects, a base set of appearance parameter values for the first object is determined, such as average values of hue, saturation and luminance. Selected regions of the object are analysed and in respect of each selected region the extent to which actual appearance parameter values deviate from the base set of apparatus parameter values is determined. The method includes storing data representation of the positions of the regions and the respective deviations from the base set of values. The first object is replaced by a second object, and the method then includes the step of applying to regions of the second object adjustments to appearance parameter values by reference to the stored data.
