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.

1. A method for generating as metadata for use in a color correction operation comprising the steps of: generating a first segment of metadata by a processor that describes a number of color correction operations to be preformed by a color correction machine;generating a second segment of metadata by said processor that specifies a color correction operation to be performed by said color correction machine; andgenerating a third segment of metadata by a processor that specifies temporal information indicating when to have said color correction machine perform said color correction operation on image data representing a sequence of moving images. 2. The method of claim 1 further comprising the additional step of: generating a fourth segment of metadata that specifies additional temporal information that is used by said color correction machine to perform a second color correction operation on an additional sequence of images. 3. The method of claim 2, the application of said color correction operation and said second color operation overlap when applied to said sequence and additional sequence of images. 4. The method for generating as metadata for use in a color correction operation comprising the step of: generating by a processor a first segment of metadata that describes a number of color correction operations to be preformed by a color correction machine;generating by said processor a second segment of metadata that specifies a color correction operation to be performed by said color correction machine; andgenerating by said processor a third segment of metadata for indicating a region of a image in which to perform said color correction operation by said color correction machine. 5. The method of claim 4, wherein said metadata indicates that said color correction operation is applied to the same region of two images selected from image data representing a sequence of images. 6. The method of claim 1, wherein said color correction operation is selected from at least one of a one dimensional color transformation, a three dimension color transformation, a predetermined matrix, and a lift, gain, and gamma function. 7. A method of performing a color correction operation comprising the steps of: determining with a processor of a color correction machine a number of color correction operations to be performed in response to received metadata; andperforming with the processor of said color correction machine the color correction operations determined in said previous step on image data and said color correction operations are performed on a specified region of an image selected from image data used for rendering a sequence of images. 8. The method of claim 7, wherein said color correction operation is selected from at least one of a one dimensional color transformation, a three dimension color transformation, a predetermined matrix, and a lift, gain, and gamma function.
