Patent ID: 8194997

Claim:
A system for converting a video from a first dynamic range to a second dynamic range, said system comprising: a. a receiver for receiving said video and for receiving a message, wherein said message comprises: i) a plurality of tone maps, each for use in converting said video from said first dynamic range to said second dynamic range, said first dynamic range and said second dynamic range each represented by respectively different bit-depths, wherein each of said tone maps is defined by a model identifier (ID) and at least one model parameter, and each of said tone maps is associated with a tone map ID, which identifies the purpose of the associated tone map, where said plurality of tone maps includes at least two types selected from the group of: (1) linear mapping with clipping; (2) a sigmoidal model; (3) a user-defined look-up table; and (4) a piecewise linear model; b. a selector for selecting a first tone map, from said plurality of tone maps, to apply to said video; and c. a tone map processor for applying said first tone map to said video, thereby producing a tone-mapped video.
