Abstract

Methods, image sensor (331; 631; 800), imaging system (605) for 3D imaging based on light triangulation comprising the image sensor, relating to provision of pixels values of image sensor pixels of a second Region Of Interest, ROI, (465; 465'; 565) based on a first ROI (365; 365'). The first ROI (365; 365') used by the image sensor (331; 631; 800) to provide first pixel values of image sensor pixels of the first ROI (365; 365') resulting from a first exposure. The second ROI (465; 465'; 565) is determined (702) according to a predetermined relation that the second ROI (465; 465'; 565) shall have to the first ROI (365; 365'). A second exposure (703) makes at least the image sensor pixels of the second ROI (465; 465'; 565) to attain second pixel values. The second ROI (465; 465'; 565) is used to provide (704) second pixels values of image sensor pixels of the second ROI (465; 465'; 565) for further processing by the image sensor (331; 631; 800).
