Charter: The Architecture Working Group will address issues relating to ICC architecture.

Specifically the group will:

1. Document the current architecture, including its functionality for the purpose of defining the baseline for further work and internal usage
2. Investigate and propose improvements and alternatives to the current architecture to address identified issues

Charter: When the ICC Profile Specification was developed, display technology was primarily CRT-based. As a result, the transform tags for the monitor support a simple additive model that is appropriate for that technology. Nowadays, there are numerous new technologies, including LCD, Led, and OLED with various types of backlighting. The simple model described by the ICC Monitor tags is inadequate to completely and adequately describe color displayed by these technologies. The predominance of the sRGB color encoding, which was developed during the CRT era, has been used for a large amount of content. New displays, especially those on mobile devices, often do not model that color encoding completing. In addition, new technologies that provide wider color gamut than sRGB are available. Unfortunately, these devices, because they do not provide a direct means to display sRGB content adequately, often yield inferior results.

The Display Working Group is created to address the aforementioned issues with the following goals:

1. Work with other groups in the ICC as well as outside organizations to fully define the problems associated with color management of display output;
2. Identify and categorize display technologies and the appropriate corresponding transform methodologies for supporting them in ICC workflows;
3. Where the current ICC specification is inadequate to the needs of display color managements, draft profile proposals to implement the algorithms and data structures developed in #2 and bring them through to acceptance by the ICC; and
4. Develop algorithms and data structures to implement the methodologies identified in #2 and #3.

Charter: To promote the use of ICC color management in High Dynamic Range (HDR) imaging.

Specifically the group will:

1. Identify issues and limitations with the current specifications, implementations and use of color management in HDR imaging.
2. Work with implementers of HDR color management, other international standard bodies, and working groups in the adoption of ICC HDR in their own specifications.
3. Develop proposals for how to include HDR in ICC workflows.
4. Prepare white papers and other educational materials to aid developers and users in the appropriate application of color management to HDR.
5. Propose revisions to ICC specifications where needed to address the needs of HDR workflows.

Charter: Enable and promote the correct and effective use of ICC color management for medical imaging.

Specifically the group will:

1. Identify issues with the implementation and use of color management for medical imaging.
2. Establish and maintain liaison relationships with the appropriate medical imaging standards development organizations, e.g. DICOM, AAPM, ACR, IEC and ISO.
3. Prepare white papers and other educational materials, and promotion activities to guide developers and users in the appropriate application of color management to medical imaging.
4. When necessary, propose new ICC specifications or revisions to existing ICC (and other) specifications to address the needs of the medical imaging community.
5. Promote the use of ICC color management in medical imaging.
