摘要

The device has an image sensor (44) with multiple sensor units for detecting of visible light and for generation of signals from the detected light. A light guidance channel (50) exhibits openings, which are adjustable to a projected image and the sensor, respectively. An interface (60) receives the sensor signals and controls the projection data of a projector, which projects the image detected from the sensor. Independent claims are also included for the following: (A) a method for calibrating projected image (B) a computer program medium for calibration of projectors.
