Abstract
A reading machine includes an image input device including a lens and a polarizer disposed over the lens, a flash and a second polarizer disposed over the flash. The image input device also includes a computing device coupled to the image input device for capturing images, the computing device, including a processor to execute instructions and a computer program product residing on a computer readable medium, the computer program product comprising instructions for causing the processor to process the captured images to recognize features in the captured images.
Claims14
A device comprising:
- an image capture device, comprising:
- a housing;
- a lens mounted in said housing, and
- a flash window mounted in said housing;
- and
- a polarizer assembly configured to be mounted on said housing, said polarizer assembly, comprising:
- a frame member;
- and
- a pair of polarizers arranged in the frame member at orthogonal polarizations, with one of the pair of polarizers positioned in the frame to cover the lens and having a linear polarization that is orthogonal to a linear polarization of the other polarizer of the pair that is positioned in the frame to cover the flash window;
- a computing device coupled to the image capture device, the computing device, comprising:
- a processor to execute instructions;
- and
- a computer program product residing on a computer readable medium, the computer program product comprising instructions for causing the processor to:
- process images captured by the image capture device to:
- recognize features in the captured images.
A case for a cell phone having an image capture device, the case comprising:
- a body portion configured to house a cell phone having an image capture device, the body portion having a window;
- and
- an accommodation for accepting in the window a polarizer assembly,
- said case further comprising said polarizer assembly affixed to the window of the case, the polarizer assembly, comprising:
- a frame member;
- and
- a pair of polarizers arranged in the frame member at orthogonal polarizations, the case and polarizer assembly configured to have one of the pair of polarizers covering a lens having a linear polarization that is orthogonal to a linear polarization of the other polarizer of the pair that covers a flash of the image capture device.
