BS ISO 22028-3:2023 Photography and graphic technology. Extended colour encodings for digital image storage, manipulation and interchange - Reference input medium metric RGB colour image encoding (RIMM RGB)
1 Scope
This document specifies a family of scene -referred extended colour gamut RGB colour image encodings designated as reference input medium metric RGB (RIMM RGB). Digital images encoded
using RIMM RGB can be manipulated, stored, transmitted, displayed or printed by digital
still picture imaging systems. Three precision levels are defined using 8-, 12- and
16-bits/channel.
An extended luminance dynamic range version of RIMM RGB is also defined, designated
as extended reference input medium metric RGB (ERIMM RGB). Two precision levels of
ERIMM RGB are defined using 12- and 16-bits/channel.
FP-RIMM RGB, a floating point version of RIMM RGB, defines the expression method of
RIMM RGB in a floating point figure. Three precision levels of FP-RIMM RGB are defined
using 16-, 32- and 64-bits/channel.
