Cross-media color reproduction
2014-2015 - IMT4072 - 5 ECTS

Expected learning outcomes

The aim of this course is to provide fundamentals and basic knowledge of cross-media color reproduction and color management on different media technology platforms. After completing this course, the students will also have an understanding of, and experience in color encodings applicable to different media platforms including setting up and evaluating a cross-media color reproduction workflow.
On completion of this course, the student will be able to:

Knowledge:

  • Describe features of the human visual system and color perception applicable to media color reproduction
  • Evaluate 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:

  • Demonstrate the problems that can occur when media platforms are not colour managed using appropriate standards
  • 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 which converts from an input-referred image state to an output-referred image state

Topic(s)

  1. Light, color and the human visual system
  2. Color characteristics of solid state cameras, scanners, projectors, displays and printers
  3. Color encodings, image states and conversions between them
  4. Measurement of color in original scenes and on output devices
  5. Gamut limitations of media technology platforms and methods of compensation
  6. Calibrating and characterizing media input and output systems
  7. Color management for video, web, broadcast, motion picture and print and workflow for cross-media color reproduction
  8. Evaluation of color reproduction quality, transforms and devices

Teaching Methods

Lectures
Laboratory work
Net Support Learning
Project work
Meeting(s)/Seminar(s)

Teaching Methods (additional text)

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 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 HiG virtual learning environment, and through other modes of contact with the course leader. There will also be tutorials and seminars which you can participate in remotely.

Form(s) of Assessment

Other

Form(s) of Assessment (additional text)

  • Project(s) (60%)
  • Computer-based written exam, 12 hours (40%)
  • Each part needs to be passed.

For the Project, students will undertake an individual task in cross-media color reproduction and provide a written rationale, analysis and discussion of results.

The laboratory work for the coursework project will be carried out individually.

The Computer-based written exam will require students to undertake a number of tasks in cross-media colour reproduction using a computer, and to document the processes involved. The exam will last for 12 hours and may be undertaken on-site at HiG or off-site; student will submit the results of the computer task and the written answers electronically.

Grading Scale

Alphabetical Scale, A(best) – F (fail)

External/internal examiner

One internal examiner

Re-sit examination

Ordinary re-sit for the Computer-based written exam. There is no re-sit examination for projects.

Coursework Requirements

All students are required to attend the two-day workshop which introduces the coursework projects.

Additional information

Most coursework projects require access to specialist equipment. As well as the required workshop sessions described above, remote students will need to attend sufficient of the scheduled lab sessions to successfully complete their project, unless they have access to suitable equipment elsewhere. Students are advised to discuss options with the course leader as early as possible if they are intending to study off-campus.
