Abstract
The present disclosure relates to a method performed by a luminance assessment system of a vehicle for monitoring of on-board vehicle image capturing device functionality compliance with a predeterminable requirement level. The luminance assessment system obtains at respective one or more time instants (t1, t2, t3), a first image and a second image. A first section of the first images and a second section of the second images respectively cover a primary region. A first luminance value of the first section and a second luminance value of the second section are measured. A luminance deviation is determined by comparing at least one of the first luminance values to at least one of the second luminance values. A determination is made that, when the luminance deviation exceeds a deviation threshold, the first image capturing device or the second image capturing device failed to function according to the requirement level.
