IMAGE SENSING DEVICE AND MEASURING SYSTEM FOR PROVIDING IMAGE DATA AND INFORMATION ON 3D-CHARACTERISTICS OF AN OBJECT

摘要

An image sensing device (130) for providing image data relating to an image of an object (120; 121; 501) comprises an image sensor (131) having a sensor area (132) for sensing light. The image sensing device (130) defines (401) Regions Of Interest, “ROIs”, (301a-303a) in the sensor area (132). Each ROI (301a; 302a; 303a) partially overlaps one or more of the other ROIs (301a-303a). The ROIs (301a-303a) are exposed individually to light from the object. The image sensing device (130) reads (403) partial image data belonging to groups respectively associated with the exposed ROIs (301a-303a) and resulting from sensed light therein. Image data relating to the image of the object is provided based on a combination of the read partial image data.
