Abstract: 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 (705). 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 (710). The image data is then rendered as a series of images (715) by a rendering device. Optionally, different regions of the image data may be subjected to different color correction operations.

Abstract: A video camera has a lens, an image sensor for generating a first video signal representative of a scenery which is imaged on the image sensor by said lens, an auxiliary image signal source providing a second video signal, an output interface for outputting a third video signal, and signal mixing means for combining said third video signal from said first and second video signals.
