| Popis: | Brightness measured by heterochromatic brightness matching or by threshold determinations is not additive, whereas for flicker and minimum border matches brightness is additive. This paper shows that when the metric for the brightness unit is determined by measuring the brightness required to attain a certain acuity, brightness is also additive. However, brightness determined with an acuity criterion is probably additive for a different reason from that advanced to explain the additivity of flicker and minimum border matches. |
