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 derived from the distinct images perceived by each eye due to their horizontal separation. This cue requires both eyes.

Conversely, monocular cues include:

• Motion parallax: A monocular cue where closer objects seem to move faster than distant ones.
• Linear perspective: A monocular cue illustrating parallel lines converging with distance.
• Texture gradient: A monocular cue showing surfaces becoming denser and less detailed farther away.

Unlike binocular disparity, monocular depth cues enable distance judgment using a single eye.
