Abstract:
A method, an apparatus and a computer program are provided. The method comprises: analyzing different color channels of an image detected by an image sensor; and adjusting, in dependence upon the analysis, at least one of: a position of a focal plane of an optical arrangement and a position of the image sensor. In some embodiments, the sharpness of different color channels of the image is compared and the adjustment depends upon the results of the comparison.
