Brightness perception and filling-in

Vision Research, 1991
Three experiments were performed in which a stimulus with homogeneous color and luminance was masked by a second stimulus containing contours. In the first experiment the target was a large white disk and the mask was a white circle concentric with the disk but of smaller radius.

Brightness perception changes related to pupil size

Vision Research, 2021
Dilating the pupils allow more quanta of light to impact the retina. Consequently, if one pupil is dilated with a pharmacological agent (Tropicamide), the brightness of a surface under observation should increase proportionally to the pupil dilation. Little is known about causal effects of changes in pupil size on perception of an object's brightness ...

Brightness perception of unrelated self-luminous colors

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 2013
The perception of brightness of unrelated self-luminous colored stimuli of the same luminance has been investigated. The Helmholtz-Kohlrausch (H-K) effect, i.e., an increase in brightness perception due to an increase in saturation, is clearly observed.

Brightness Perception in Complex Fields

Journal of the Optical Society of America, 1967
Results of brightness-scaling experiments with complex stimulus fields are reported. A family of brightness functions has been computed from the data for complex stimuli such as photographic reproductions viewed with both illuminated and dark surrounds. The resulting brightness vs luminance functions are not simple power functions.

Instrument for Measuring Relative Brightness Perception

American Journal of Ophthalmology, 1994
Neuro-ophthalmic disorders may cause a subjective difference in the brightness perceived by each eye. We developed a unique clinical device to measure this difference. The device consists of a disk equipped with graded neutral-density filters that fits into a View-Master stereo viewer (View-Master International Group, Inc., Portland, Oregon).

Instructions and Knowledge of the Situation in Brightness Perception

The American Journal of Psychology, 1970
The influence of information and instructions on brightness perception was investigated under conditions where either ratio or retinal matches were possible. Unlike most earlier studies, this one found no effect of experience: both trained and control groups showed identical ratio responses.

The Effects of Brightness Difference on Visual Perception of Characters

2021 22nd IEEE International Conference on Industrial Technology (ICIT), 2021
The visual perception of characters depends on the color contrast difference between the foreground and the background. In the human-machine interface, the black characters on a white background or white characters on a black background are the most commonly used color combinations.
