Abstract: An arrangement of an image recording apparatus 1 with a storage device (9) on a side of an interface (8) with a camera control unit (2) that faces the camera head (3) and for implementing in the camera control unit (2) a configuration unit (10) with which camera-head-specific information is readable from the storage device (9) and transmittable to an image signal pre-processing unit (4) of the camera head (3) for configuration.

Abstract: The present invention provides a method and system for determining and providing color metadata for a downlink data channel. In accordance with the present invention color metadata is determined such that gamut mapping is defined by a transmitted source gamut which enables adapted mapping that preserves saturation and contrast levels of the source for a downlink data channel. The metadata is then provided to a downlink data channel for color management.

Abstract: A method and system are provided for look data definition and transmission over a high definition multi-media interface (HDMI). The method includes generating metadata for video content. The metadata is used for altering the video content before display thereof by accounting for variations between different display devices and variations between different creative intents by a content creator. The method further includes preparing the video content and the metadata for transmission over a high definition multimedia interface.

Abstract: Method of mapping source colors from a source color device having an actual source gamut that is represented by a source convex (gamut boundary descriptor) and a source non-convex into target colors for a target color device having an actual target gamut that is represented by a target convex and a target non-convex, comprising, 1—if the source color to map is located outside the source non-convex, a pre-mapping step that maps the source color into the source non-convex, 2—if the mapped target color is located outside the target non-convex, a post-mapping step that maps the target color into the target non-convex. This method allows precise gamut mapping while allowing also for simple geometrical operations using convex gamuts.

Abstract: The invention relates to a method for correcting chromatic aberration in an image capture device like a camera. It comprises the steps of determining, in the image, an analyzing area around the current pixel, comparing, for the current pixel, a first color component data of a first block of pixels comprising the current pixel to a second color component data of pixels of second blocks of pixels having the same size as the first block within the analyzing area, selecting the second block of pixels having the highest correlation with the first block of pixels, determining the shift vector to be applied to the selected second block in order that said selected second block coincides spatially with said first block of pixels, and shifting the second color component data of the pixel of the selected second block corresponding to the current pixel in accordance with the shift vector so as to correct chromatic aberration.

Abstract: A method and system for generating look data for video content include a generator for generating look data for a scene of the video content. In one embodiment, the look data includes at least one control parameter for affecting at least one display attribute of the respective scene of the video content. The method and system further include a transmission preparation device for generating at least one look data packet from the look data, the at least one look data packet intended to be delivered with the video content to enable the at least one look data packet to be applied to the video content such that when the at least one look data packet is applied to the video content, the at least one display attribute of the video content is changed in accordance with the at least one control parameter of the at least one look data packet.

Abstract: A temporally recursive chrominance signal noise reduction can be achieved by subtracting a delayed version of the chrominance output signal from the chrominance input signal and by multiplying the related difference signal by a variable share factor and adding the resulting signal to the chrominance output signal, for achieving different degrees of noise reduction. From the difference signal a motion representative value and a value representing the presence of a smear effect are calculated and used to calculate the variable factor. After having been multiplied by this factor, the difference signal is combined with a frame-delayed version of the chrominance output signal in order to form the noise-reduced chrominance output signal.
