Describe each system and provide at least one perceptual disadvantage for each of the following three-dimensional display methods: Anaglyph.
Describe each system and provide at least one perceptual disadvantage for each of the following three-dimensional display methods: Anaglyph.
Answer: The name given to the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different colors, typically red and cyan. Each of the two images reaches one eye, revealing an integrated stereoscopic image. The visual cortex of the brain fuses this into perception of a three dimensional scene or composition.
Disadvantages:
Ghosting: If some colour from the left image gets into the right eye (and vice versa) a faintly coloured "ghost" will be seen. Increasing the parallax (stereo depth) separates the two images and makes ghosting worse.
Retinal rivalry: If the brightness (luminance) of the two images is not the same in each eye, the effect is unpleasant.
Wrong colors: Each eye is getting only part of the RGB colour range. The viewer is always partially colour-blind and/or has retinal rivalry.
