Perception of transparency significantly influences perceived brightness, with transparent overlays making test patches appear brighter. This effect is strongest with stereo depth cues and lower transmittance.

Area of Science:

  • Visual perception
  • Color science
  • Psychophysics

Background:

  • The perceived brightness of an object is influenced by its surrounding context.
  • Illusory transparency can be perceived under specific visual conditions.
  • The relationship between perceived transparency and brightness requires further investigation.

Purpose of the Study:

  • To investigate how perceived transparency affects the perceived brightness of a test patch.
  • To determine the role of stereo depth cues and transmittance in the transparency-brightness relationship.
  • To explore how the luminance of the test patch and its surround interact with transparency effects.

Main Methods:

  • Participants adjusted the brightness of a test patch under different surround conditions.

Related Experiment Videos

  • Conditions included surrounds interpreted as transparent overlays versus differing reflectance regions.
  • Luminance and spatial extent of the inner surround were controlled across conditions.

    • Main Results:

    • Perceived brightness of the test patch was significantly affected by the configuration condition.
    • Test patch brightness was elevated when conditions favored transparency perception.
    • The effect was largest with stereo depth cues and increased with decreasing virtual transmittance.

    Conclusions:

    • Perceived transparency is a significant factor modulating perceived brightness.
    • Stereo depth cues and reduced virtual transmittance enhance the brightness effect of transparency.
    • The interaction between transparency and brightness is most pronounced at intermediate luminances.
