摘要:
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.

Embodiments of the present invention provide a method, apparatus and system for digital cinema color management. In one embodiment, a digital cinema color management system includes a projection device configured to project image content and a color meter configured to measure color levels of the projected image content. A control device is also provided including a validation module configured for validating the measured color levels of the color meter for preventing the creation of erroneous correction data. A calibration module determines if calibration of the color levels is required and provides real-time corrective color information to a projector.
摘要:
A method and a system for identifying a copy of an image sequence which is presented on a screen. At least one identifier distinct from the image sequence can be projected through the screen such that the identifier is displayed using visible light along with the image sequence. The identifier can be presented at periodic intervals and can define a theater location, a date and/or a time. A color and/or an illumination of at least a portion of the image sequence presentation can be measured. Based on the measured illumination and/or color, a projection brightness and/or color can be determined for the identifier. Also, a location on the screen through which the identifier should be projected can be determined.
摘要:
A method and system for mastering and distributing enhanced color space content for different display devices (target color space) having display capabilities beyond that of CRT color space. The content creator(s) establishes base or reference color space and enhanced color space data for each target color space. The enhanced color space data is stored as metadata and transmitted over an enhanced color channel separately from the base/reference color space. Both the base/reference data and metadata are encoded before transmission and decoded on the consumer side either by a separate decoder or a display device having an integrated decoder. In other aspects of the invention, auxiliary data relating to the target color space, such as, for example, brightness, luminance, contrast and other display settings can be transmitted over the enhanced color channel and decoded to control the target color space settings (i.e., display settings). The color adjustment metadata could be included in the auxiliary data or maintained separate from the same depending on the desired implementation.
