Depth enhancing screen

Abstract

The present disclosure relates to a depth-enhancing screen for producing a simulated 3D image. The screen comprises a multi-curved Fresnel lens which when viewed in cross-section along the or each longest line linking two points on the edge of the lens, has a curved cross-section with an apex in the central region of the lens, and wherein each end of the curve flattens before it reaches the edge of the lens.

Description

technical field [0001] The present disclosure relates to a depth-enhancing screen for producing images with enhanced depth or with simulated three-dimensional effects. Background technique [0002] Depth perception is the visual ability to perceive the world in three-dimensional space. Humans (and other animals) perceive depth using a variety of monocular cues (ie, cues provided by input from only one eye) and binocular cues (ie, cues that require input from both eyes). [0003] Motion parallax is a monocular cue that can affect depth perception. As the observer moves, the apparent relative motion of multiple stationary objects relative to the background gives clues to their relative distances. Slight movement of the observer combines with the object, resulting in a better perception of depth. However, such movement does not contribute to depth perception when viewing images on a flat-screen TV or computer screen, since there is no relative movement between the objects sh...

In practice, the belly-shaped effect may be more pronounced and may extend to more of the screen than the example shown in Figure 2
