- viewing conditions
- image quality
- the relative nature of lightness sensitivity; logarithms
- chromatic adaptation and white balancing
- end-to-end gamma
- image data adjustments based upon display surround and contrast ratio
Image formats
- SD, HD, 2K and 4K
- visual acuity, viewing angle, and resolution requirements
- frame rate requirements
- video and file-based (data) approaches
Optical formats
- 2/3-inch (HD) format, and beamsplitter (prism) cameras
