Method and apparatus for deblurring an image

摘要

A method and apparatus for reducing blur in an image generated by an imaging system is provided. A blur model for the image is identified with respect to an exposure time for the image using a sequence of reference images of an artificial reference point object generated during the exposure time for the image. A source of the artificial reference point object is inertially stabilized over the exposure time. The image is deconvolved with the blur model identified for the image to form a modified image having a desired reduction in blur relative to the image generated by the imaging system.

1. A method for reducing blur in an image generated by an imaging system comprising an optical system, an inertially stabilized source, and an array of image sensors, the method comprising:
focusing, using the optical system, light emanating from a scene onto the array of image sensors; detecting, using the array of image sensors, the light to form the image; generating an artificial reference point using the inertially stabilized source; directing the artificial reference point towards the optical system such that the array of image sensors also detects the artificial reference point and not a reflection of the artificial reference point from the scene; identifying a blur model for the image with respect to an exposure time for the image using a sequence of reference images of the artificial reference point object generated during the exposure time; and deconvolving the image with the blur model to form a modified image having a reduction in blur relative to the image.
