Next generation imaging methods and systems

摘要

Novel imaging arrangements are detailed. One comprises an optical array sensor with plural photo-electron generating regions dispersed at two or more layers in the structure. Two of these photo-electron generating regions are vertically separated by at least 10 microns—making the sensor useful for sensing objects at focal distances ranging from less than ten inches, out to infinity. The photosites may be spectrally selective. One such arrangement includes a top CMOS sensor array that passes 25% or more of the visible incident light into the structure. A second CMOS sensor array can be provided at a bottom of the structure, for receiving light that was not transduced to photo-electrons elsewhere in the sensor. Another arrangement involves movement of a camera sensor, in a repetitive tracking/pop-back motion, to reduce motion blur in individual frames of a video sequence. A great number of other arrangements are also detailed.

主权项

1. A method employing a video camera system, said system including a lens coupled to a body, and an image sensor, the image sensor lying in an image plane, the method comprising the acts:
sensing a uniform motion of the video camera system while capturing video imagery, said capturing of video imagery comprising the capturing of a still image frame N times a second, said uniform motion of the video camera system resulting in a uniform movement of image features across the image plane, said uniform motion being deliberate rather than unintended; repeatedly performing a uniform physical tracking movement of the image sensor, within the body, in a direction that tracks said uniform movement of image features across the image plane, followed by a uniform popping movement that returns the image sensor back to an original position it occupied at a beginning of said uniform tracking movement; wherein said tracking and popping movements are repeated N times a second.
