Question

Which of the following is not a depth cue that is potentially available for only one eye?

• A. Binocular Disparity
• B. Motion Parallax
• C. Linear Perspective
• D. Texture Gradient

Hint:

Binocular disparity uses both eyes.

Answer 1

The Correct Option is A

Binocular disparity is a depth cue that relies on the slightly different images seen by each eye due to their horizontal separation. This cue is unavailable to one eye.

In contrast:

• Motion parallax: A monocular cue where objects closer to the observer appear to move faster than those farther away.
• Linear perspective: A monocular cue where parallel lines converge as they recede into the distance.
• Texture gradient: A monocular cue where surfaces appear denser and less detailed as they recede into the distance.

Monocular depth cues can be utilized by a single eye to judge distance, unlike binocular disparity.
