Abstract: In the technical field of video cameras gamma correction is an often used technique to compensate the non-linear effects of the CRT (cathode ray tube), in order to enhance visibility in images to be displayed. Gamma correction is—by way of example—expressed by the gamma function: A process for enhancing detail visibility in an input image comprising a step of applying a first transfer function (11) to the input image, thereby generating an intermediate image; a step of performing a statistical measurement (12), Mmt (2) on the intermediate image; a step of applying a second transfer function (14) to the intermediate image, thereby generating an output image; a step of performing a statistical measurement (15), Mmt (3) on the output image, a step of determining gain parameters gg, gk for the first and the second transfer function (11, 14) on basis of the statistical measurement results (8, 12, 15), Mmt (1), Mmt (2), Mmt (3) is proposed.

Abstract: RGB to NTSC/PAL encoders—as an example—commonly convert red, green and blue colour component signals (RGB) into their corresponding luminance (luma) and chrominance (chroma) signals in the respective standards in order to generate a composite video signal which can be used in connection with television sets and the like. Thereby, roughly spoken, the luminance signal represents the monochrome or black-and-white portion of the composite video signal and the chrominance signal represents the colour portion of the composite video signal.

Abstract: A method and system for embedding an authentication signature in an audio-visual signal such that only a part of an entire frame of the audio-visual signal is stored in a memory while the signature bits are calculated and the watermark is embedded. A signature is formed based on a first portion of said audio-visual signal, whereby said first portion is a pattern of horizontal lines of said audio-visual signal and has fewer lines than the number of lines of the entire audio-visual signal. Thereafter the signature generated is embedded in said audio-visual signal in the first portion and/or in another portion of the frame to be authenticated, whereby the other portion also is a pattern of horizontal lines. Thus only memory for some lines instead for all lines of the audio-visual signal is needed. In the case of an interlaced audio-visual signal, the first portion is preferably the first field of a frame of said audio-visual signal and the second portion is the second field of said audio-visual signal.

Abstract: A multi-picture in picture system in which each camera is coupled in a daisy chain adds its part of the complete picture on a CVBS-line. The television/monitor doesn't have to prepare the complete picture because each camera does it. Furthermore, no problems with locking occur because each camera adds its picture at the “place” where it is also locked.

Abstract: Do display more than one picture on a television/monitor multi picture in picture systems are known.

Abstract: A method of processing images for constructing a target image (Io) from adjacent images having a fixed frame line and referred to as source images (I1, . . . , Ii, Ij, . . . , In), the source and target images having substantially common view points. This method includes the steps of: digitizing the images, determining, for one of the pixels of the target image (Io), the address (Aq) of a corresponding point in one of all source images (Ij), determining the luminance value (F) at this corresponding point, assigning the luminance value (F) of this corresponding pixel to the initial pixel in the target image (Io), and repeating these steps for each pixel of the target image (Io). A device for performing this method includes a system of n fixed real cameras (C1, . . . , Cn) which provide n adjacent source images (I1, . . .
