Patent ID: 7440637

Claim:
A method for imaging, comprising: a first step of using an imager to perform a first set of measurements for generating a first image value, the first set of measurements including at least one measurement of an intensity of a first radiation ray bundle from a first scene region, the first radiation ray bundle having a first chief ray in a reference frame of the imager, the imager having a first intensity sensitivity characteristic with respect to radiation ray bundles having the first chief ray, and the imager having a first dynamic range with respect to intensities of the radiation ray bundles having the first chief ray; a second step of using the imager to perform a set of second measurements for generating a second image value, the second set of measurements comprising at least one measurement of an intensity of a second radiation ray bundle emanating from the first scene region, the second radiation ray bundle having a second chief ray in the reference frame of the imager, the second chief ray being different from the first chief ray, the imager having a second intensity sensitivity characteristic with respect to radiation ray bundles having the second chief ray, the second intensity sensitivity characteristic being different from the first intensity sensitivity characteristic, and the imager having a second dynamic range with respect to intensities of the radiation ray bundles having the second chief ray; and applying a mosaicing operation to the first and second image values, for generating a third image value having associated therewith a third dynamic range of the imager with respect to at least one of the intensities of the first and second radiation ray bundles, the third dynamic range being greater than at least one of the first and second dynamic ranges of the imager.
