Cross-media Color Reproduction

• Light, color and the human visual system
• Measurement of color
• Color science and colorimetry
• Color spaces, colour encodings and transforms between them
• Color reproduction objectives and how to achieve them
• Color characteristics of solid state cameras, scanners, projectors, displays and printers
• Calibrating and characterizing media input and output systems
• Gamut limitations of media technology platforms and methods of compensation
• Color management applications: web, video, broadcast, motion picture, HDR and print
• Evaluation of color reproduction quality, transforms and devices

The aim of this course is to provide fundamentals and basic knowledge of color science and cross-media color reproduction on different media technology platforms. Students will obtain an understanding of fundamental color science, together with experience in color encodings and the associated transforms applicable to different media. They will also be able to set up and evaluate a cross-media color reproduction workflow. On completion of this course, the student will be able to:

Knowledge:

• Describe in their own words the main features of the human visual system and color perception
• Describe in their own words the principles and applications of CIE colorimetry, including the role of standard and custom colorimetric observers
• Describe in their own words the conditions required for a visual color match across different media
• Compare the methods used to produce color on different media technology platforms
• Define the image states and associated color encodings applicable to different media technology platforms, and show how to convert between them

Skills and general competence:

• Measure different types of colour stimuli
• Calculate spectral and colorimetric quantities
• Quantify differences between colors
• Apply transforms between different adapting states
• Demonstrate the production of colours defined in terms of human colour appearance on different media technology platforms
• Set up and evaluate a cross-media color reproduction workflow

• Lectures -Seminars/Workshops
• Lab work
• Project work
• E-learning

Additional information:

• All the lectures will be made available as pdfs, and each session has a detailed recommended reading list which can be seen in the course description above.
• Coursework projects will be introduced over a two-day workshop in the first or second week of the course. The workshop will include an introduction to the lab resources needed for each project. This workshop is required for all participants, including remote students.

Teaching methods for remote students: off-campus students are supported through the NTNU virtual learning environment (Blackboard), and through other modes of contact with the course leader. There will also be tutorials and seminars in which students can participate in remotely.

Compulsory requirements:

• All students are required to attend the two-day workshop (campus Gjøvik) which introduces the coursework projects.
