A method presents metadata that is used for determining the color correction processes to be performed on image data representing a sequence of moving images. Instructions in the metadata controls how many color corrections are to be performed and when such operations occur. The image data is then subjected to the specified color correction operations that are performed at specified times and in a determined order. The image data is then rendered as a series of images by a rendering device. Optionally, different regions of the image data may be subjected to different color correction operations.

Method and apparatus for color decision metadata generation

In high-end professional video cameras, a triax system transfers various signals back and forth over a single coaxial cable between the camera and a base unit using frequency multiplexing. Current low-cost camera systems transfer several signals as analogue signals over separate wires or cables. However, a standard serial SDI signal from the camera to a base unit replaces the analogue camera CVBS video output signal achieving a maximum data rate of 270 Mbit/s. To improve efficiency, a single SDI or HDSDI connection transmits a digital playback video signal as well as a digital teleprompter video signal from the base unit to the camera. A one-dimensional adaptive dynamic range compression reduces the data word length of the two video signals transmitted via the SDI/HDSDI connection. A smaller data word length is assigned to one of the two video signals than to the data word length of the other one.

An advantageous production system comprises at least a camera producing a raw digital signal and a processing circuit for generating a processed video signal from the raw digital signal. In a control area, at least a camera control interface is able to set at least a parameter in the processing circuit. The processing circuit is located in the control area. An image capturing system for such a production system is also presented.

A method for processing at least a part of a color picture comprises at least one pixel defined by a plurality of color values. Each color value is variable between black and a color clip value. The method comprises, determining for each color value the quantity of the color value above the common clip value, computing a linear combination of the quantities, and for at least one of the color values, outputting a processed color value based on the linear combination.
