摘要： The invention relates to a method and a system for digitally processing of frequently updated images from a camera.The system comprises at least one camera (2), at least one display unit, a network (6) for connecting the at least one camera with at least one display unit, and an image processing means (30).The image processing means comprises means for defining a first scaling area and a peripheral scaling area, which is enclosing the first scaling area, within an acquired digital image, and means for scaling the peripheral scaling area differently than the first scaling area so that the peripheral scaling area is downscaled in relation to the first scaling area, wherein the first scaling area is uniformly scaled in both a vertical and a horizontal direction.

摘要： Method and apparatus for combining a first video signal and a second video signal. The method comprising the act of replacing data in the second video signal with corresponding, in respect of a position within an image, data from the first video signal when said data in the second video signal represent a predefined repetitive pattern. The apparatus comprising a first input for input of the first video signal; a second input for input of the second video signal; an output for output of a third video signal; a keying-pattern detector connected to said second input for detecting a predefined repetitive pattern, wherein said keying-pattern detector comprises a means for receiving and/or storing a representation of the predefined repetitive pattern, and an output that is arranged to provide a signal indicating whether said predefined repetitive pattern is detected or not; and a video switch connected to said first input, said second input, said output and said output of the keying-pattern detector for continuously selecting a video signal from one of the first and second input to be represented in a third video signal, said selection being controlled by a signal from the output of the keying-pattern detector.
