Abstract

Arrangements and method, performed by one or more devices (205; 231; 331; 1000), for providing information indicative of an intensity peak width (371; 471; 571) of an intensity peak (363; 463; 563) along a pixel line (352-m) of pixels (366; 466; 566) comprising the intensity peak (363; 463; 563). Said pixels corresponding to pixel elements of an image sensing area (351) of an image sensor (231; 331). Said intensity peak (363; 463; 563) being formed of such reflected light sensed by the image sensor (231; 331). A first value is computed (601) comprising a magnitude of a lower order Discrete Fourier Transform, DFT, coefficient (473; 573) regarding pixel intensity values for pixels (366; 466; 566) along the pixel line (352-m) that are comprising the intensity peak (363; 463; 563). A second value is computed (602) comprising a magnitude of a another, higher order DFT coefficient (473; 573) regarding pixel intensity values for pixels (366; 466; 566) along the pixel line (352-m) that are comprising the intensity peak (363; 463; 563). Said information indicative of the intensity peak width (371; 471; 571) is provided (603) based on said first and second values.
