Resolution enhancement

摘要

A method of enhancing input imaging resolution includes sequentially blocking light from different portions of an object with a series of resolution-enhancing patterns displayed between the object and an image detector. The method further includes detecting light filtered by the series of resolution-enhancing patterns and integrating light detected while different resolution-enhancing patterns of the series of resolution-enhancing patterns are displayed between the object and the detector.

1. An image detection system, comprising:
a display surface configured to visually present a visual display image; a light valve; a detector positioned to detect light travelling from an object through the light valve; and a controller configured to:
cause the light valve to sequentially display a series of resolution-enhancing patterns to sequentially block light from different portions of the object;determine an object area on the display surface where the object is located while the display surface visually presents the visual display image;confine sequential display of the series of resolution-enhancing patterns to the object area; and integrate light detected by the detector at different times during sequential display of the resolution-enhancing patterns without disrupting visual presentation of the visual display image except where registered with the object.
