SYSTYEM AND METHOD FOR IMPROVED COMPUTATIONAL IMAGING

摘要

A system and method for computing a digital image of a scene, where the digital image contains enhanced depth information are disclosed. Embodiments of the present invention form a light distribution on a focal-plane array, where the light distribution is based on an optical image of the scene formed by a lens system. During the exposure period of the focal-plane array, longitudinal and transverse motion are imparted between the light distribution and the focal-plane array, which encodes depth information on the blur kernel of the lens system, thereby generating an encoded digital output signal. A depth- information-enhanced digital image of the scene is computed by deconvolving the encoded digital output signal with the blur kernel of the lens system and a model of the transverse motion.
