Abstract: An image system (100) comprising a camera (110), a control unit (120), a processing unit (130), one or more illumination devices (140). The image system (100) is configured to obtain a distance matrix for a scene. Each cell of the distance matrix corresponds to a zone of the scene and a value in each cell represents the distance from an object in the zone to the camera. The image system is further configured to obtain an illumination intensity matrix for the scene. Each cell of the illumination intensity matrix corresponds to a zone of the scene and a value in each cell represents illumination intensity of one or more illumination devices in each zone of the scene. The image system is further configured to generate a compensation matrix based on the illumination intensity matrix and the distance matrix and generate an image of the scene based on the compensation matrix.
