Compensation for young observer
Compensation for elderly observer
The images below compensate for the loss of brightness when shown on a display of 10 cd/m2 peak luminance instead of 200 cd/m2. Different compensation is used for young and elderly observers, depending on their avarage sensitivity.
Note that the results are computed for an average observer. Individual variations or patological changes in vision can have stronger impact than the age-related effects. The results assume compensated refraction.
The images are best seen on a display of about 200 cd/m2 peak luminance, closely reproducing the sRGB colour space. The images were generated for a distance of approx. 0.46 m on a 24 inch monitor (angular resolution of 30 pixels per visual degree).
