Contrast sensitivity measurements as a function of frequency.įigure 5. The combination of both can reproduce contrast in excess of 1,000,000:1.įigure 4. It uses a projector (DLP) as an spatially modulated backlight for the LCD screen with the removed backlight. The photograph shows the HDR display in Cambridge, capable of displaying luminance levels up to 35,000 cd/m 2. The spatio-chromatic CSF was measured on two HDR displays: one located in Cambridge, another in Liverpool. Poster Presentation at Women in Vision UK Meeting, 13 December 2019, Belfast, UK.

Code for the CIC paper model - the model predicts contrast sensitivity for any colour direction and was fitted to 5 independent datasets, as described in the CIC28 paper.

Code for the JoV paper model - the model predicts contrast sensitivity for the three colour directions in the DKL colour space and was fitted to the data presented in the JoV paper.

This page is still under construction and it will be updated in the future. This model is intended for applications in high dynamic range imaging. Based on these measurements, we developed a model that predicts contrast sensitivity for the average observer. We found that achromatic contrast sensitivity has an inverted U-shape as a function of background luminance, with peak sensitivity at 200 cd/m 2, while red-green and yellow-violet contrast sensitivities were monotonic functions of background luminance, saturating at 200 cd/m 2. Stimuli were Gabor patches of various spatial frequencies (0.125 to 6 cpd), displayed on a high dynamic range display (peak luminance: 15,000 cd/m 2). Here, we measured contrast sensitivities at background luminances from 0.02 cd/m 2 to 7000 cd/m 2 and for three color directions (black-white or achromatic, red-green, and yellow-violet). However, little is known about CSFs at luminances above 1000 cd/m 2, especially for color. AbstractĬontrast sensitivity functions (CSFs) characterize the sensitivity of the human visual system at different spatial frequencies. A model of spatio-chromatic sensitivity under mesopic and photopic light levels.
