Abstract
A method and an image processing device for detecting a portion of an image that is dominated by infrared (IR) light of at least one predetermined IR wavelength are disclosed. A set of phase pixel values for setting focus in the image is obtained. Each of the phase pixel values is compared to a first threshold related to phase shift occurring due to difference between at least a wavelength of the first colour component and said at least one predetermined IR wavelength. Moreover, in case a phase pixel value satisfies the first threshold, it is determined that the respective location associated with said phase pixel value is included in the portion of the image that is dominated by the IR light. A computer program and a computer program carrier are also disclosed.
