There is anecdotal evidence that sharp luminance information masks chromatic blur. Here, we aim to quantify this effect and investigate what may be the underlying reasons for it.
Sharp luminance information masks chromatic blur in all the conditions we tested. This masking effect is not caused by poor acuity in the colour channels, higher effective contrast of luminance information or differences in the statistical regularities of the signals.
