Abstract
Apparatus and methods for colour grading may be implemented to improve the efficiency of colour grading digital content. Features of the apparatus and methods include: automatic detection of differences between image data and rendered images, automatic suggestions for colour grading, detection and communication of temporal effects, guidance for selecting an order of frames for grading, automated QC processes, and/or reference monitor emulation.
Claims22
An apparatus comprising:
- an input system operative to receive image data for display on a reference monitor;
- a data processor configured to process image data received at the first input to identify differences between an image specified by the image data and a rendering of the image by the reference monitor and to generate difference data representing the differences;
- an output system operative to present the difference data,
- wherein the data processor is configured to compare the image data to performance characteristics of the reference monitor which define a performance envelope and to determine the difference by identifying pixels of the image data that have pixel values outside of the performance envelope of the reference monitor.

An apparatus comprising:
- an input system operative to receive image data for display on a reference monitor;
- a data processor configured to simulate operation of one or more other monitors different from the reference monitors to render the image data and to yield simulated rendered image data for each of the one or more other monitors and output the simulated rendered image data for one of the one or more other monitors for display on the reference monitor,
- wherein the data processor is configured to compare the image data to performance characteristics of the reference monitor which define a performance envelope and to determine the difference by identifying pixels of the image data that have pixel values outside of the performance envelope of the reference monitor.
An apparatus comprising:
- an input system operative to receive image data for display on a reference monitor;
- a data processor configured to process image data received at the first input, a data analyzer that is configured to process the image data to collect data regarding each frame of a set of frames defined by the image data;
- a database connected to store the collected data and configured to associate items of the collected data with corresponding ones of the frames of the image data;
- and
- an output system operative to present the collected data,
- wherein the data processor is configured to compare the image data to performance characteristics of the reference monitor which define a performance envelope and to determine the difference by identifying pixels of the image data that have pixel values outside of the performance envelope of the reference monitor.
