Methods and systems for tone mapping messaging, image receiving device, and image sending device

摘要

A system includes: an image receiving section (142) which receives an image and a message; a map selecting section (148) which selects a first tone map applied to the image from plural tone maps used for converting an image from a first dynamic range to a second dynamic range; and a tone mapping section (144B) which generates a tone-mapped image by applying the first tone map to the image. The message include plural tone maps. Each of the tone maps is defined by a tone map model identifier and at least one tone map model parameter. Also, each of the tone maps is associated with a tone map identifier by which the objective of the tone map is identified. With this arrangement, a method and system for sending tone map data to an image receiver are provided.
