Filed:

Mar 9, 2011

Appl. No.:

13/043769

Inventors:

Andy Lai Lin - Parsippany NJ, US

International Classification:

G02B 26/00
H01J 3/16

US Classification:

250216, 359291

Abstract:

A device for sensing light comprises a light sensor, one or more intermediate mirrors, a micromirror array including a plurality of independently positionable micromirrors, wherein a first micromirror in the micromirror array is positionable in a first position such that light reflected by the first micromirror while in the first position is reflected toward a first region on one of the one or more intermediate mirrors, wherein the light reflected toward the first region on one of the one or more intermediate mirrors is further reflected to the light sensor, and a lens configured to direct light toward the micromirror array.

International Classification:

G06K 9/34

US Classification:

382154, 382173

Abstract:

Systems and methods for evaluating images segment a computational image into sub-images based on spectral information in the computational image, generate respective morphological signatures for the sub-images, generate respective spectral signatures for the sub-images, and generate a resulting image signature based on the morphological signatures and the spectral signatures.

International Classification:

H04N 5/76

US Classification:

34823199, 348E05031

Abstract:

A method for adaptive spectral image capture that may be performed via an image capture device is disclosed. A default capture parameter is applied to an imaging assembly and a sample image of a scene is captured by an image capture device. The sample image is analyzed to identify transition zones between multiple different regions. An initial guess as to which spectral regions a filter mode might work best is obtained based on dominant transition region spectrum and a first iterated step in which numerical values for the filter mode are calculated. A second iterated step in which each such filter mode is evaluated for effectiveness against other filter modes. The regions in which a specific filter mode works best becomes associated with the filer mode and these regions become the guess for the next iteration.

Abstract:

A spectral capture parameter is adjusted for capturing successive frames of motion image data. Spectral content in a first region of a current frame is compared to spectral content in a counterpart region in a previous frame. It is determined whether the spectral content has changed by more than a threshold value, based on the comparison. Responsive to a determination that the spectral content has changed by more than the threshold value, the spectral capture parameter for the first region is adjusted, and the adjusted spectral capture parameter is applied to an imaging system for capture of a successive frame.
