DEVICE, METHOD AND COMPUTER PROGRAM FOR DETERMINING A SHARPNESS MEASURE FOR AN IMAGE

摘要

Embodiments relate to a concept for determining a sharpness measure for an image, comprising: providing (110; 210) a digital grey-scale image of the image; determining (120; 220) a binary image of the image on the basis of the grey-scale image; detecting (130; 230) at least one position of an edge in the binary image; determining (140; 240) at least one grey-scale gradient in a vicinity of the at least one detected position of an edge in the digital grey-scale image; and providing (150; 250) the sharpness measure on the basis of the at least one determined grey-scale gradient.
