METHODS AND SYSTEMS FOR READING AN IMAGE SENSOR BASED ON A TRAJECTORY
摘要
<p>An optical system can provides a distorted image of an object within a field of view onto sensing pixels of an image capturing device. The optical system can expand the image in a center of the field of view and compress the image in a periphery or introduce other distortion. The distortion intentionally introduced by the optical system is corrected when the sensing pixels are read to remove some or all of the distortion and thereby produce a "rectified" image. The pixels can be read along a trajectory corresponding to a curvature map of the distorted image to rectify distortions during pixel read out, rather than waiting until all or substantially all of the sensing pixels have been read. Sensor logic and/or algorithms can be used in removing the distortion.</p>
