Abstract
An image capturing device captures a first image of the scene without illuminating the scene with IR radiation. The image capturing device determines a first value of a measure relating to contrast for the first image. When the first value indicates that a first contrast of the first image less than a first threshold value, the image capturing device captures a second image of the scene while illuminating the scene with IR radiation. The image capturing device determines a second value of the measure relating to contrast for the second image. When a difference between the first contrast and a second contrast, indicated by the second value, is greater than a second threshold value, the image capturing device determines that there is fog in the scene. A computer program and a computer program carrier are also disclosed.
