Here's the hierarchy of importance for HDTV-picture-quality (PQ)
- Optimal Black level of Image
- Contrast Ratio (Dynamic Range)
- Accurate Gray scale & Colors
- Image Resolution (amount of detail)
- Quality Source material
How is PQ affected by the viewing environment?
PQ is impacted by subjective & environmental factors...
1. Subjective factors
- Individuals have different physical vision abilities
- A person who is slightly cross eyed, will likely have poor depth perception
- What I'm able to see, may not be what you're able to see
2. Environmental factors
2.1 Light-controlled viewing environment
- Movie theaters are dark, light-controlled environments
- Home theaters are dark, light-controlled environments
- 'Shadow detail' is visible in Dark scenes/shadows
- 'Bright' scenes can overpower the viewer, causing eye-fatigue
- Specific video mode is used to adjust the Black level & Brightness level to optimize dynamic range without loosing shadow or bright details
2.2 Ambient-light (moderate to bright) viewing environment
- Great room, family room environments
- 'Shadow detail' is easily lost unless special adjustments to black level is made
- 'Bright' scenes need to be adjusted to optimize for ambient light
- Specific video mode, different from the light-controlled mode, is used to adjust the Black level & Brightness level to optimize dynamic rage without loosing shadow or bright detail
How do you get optimum PQ?
Adjust your video equipment to perform it's best in your viewing environment
