Question:
The human eye perception is limited to approximately
The human eye perception is limited to approximately
Show Hint
The ability to distinguish different gray levels is crucial in image processing and vision-based applications especially in low-contrast environments
Updated On: Jan 17, 2026
- 16 gray levels
- 32 gray levels
- 64 gray levels
- 128 gray levels
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The human eye can typically distinguish around 64 different shades of gray in varying lighting conditions which is why the perception of gray levels is limited to around 64 This is a physiological limitation of the human visual system
