Abstract: A method, apparatus and system for providing color grading or color correction for displays includes a plurality of virtual device models where each virtual device model has a virtual model specification (VMS) which controls a display feature. Each display includes a display specification including a display requirement or requirements. An apparatus of the present invention is configured to compare the display feature of at least one VMS against the display requirement of the display specification to determine a best match therebetween to select a virtual device model to control a display picture. Color correction is further provided in post production using the VMS to provide consistency across multiple display types.

Abstract: A method, apparatus and system for transforming a calorimetric adjustment of a sequence of images from an input color space into an output color space includes a color adjustment device for determining a transformation table for converting the input color space of the sequence of images to an output color space, for applying a first order approximation to at least one subset of the sequence of images, the subsets of the sequence of images defined by the transformation table, and if the sequence of images has not reached convergence, for applying a second order approximation to at least one subset of the sequence of images. In one embodiment, the color components of the output color space are defined by a combination of intermediate terms, where the number of the intermediate terms corresponds to the number of input color space components. The transform is configured to survive a video distribution workflow.
