Abstract: In some examples, a light source is controlled to output light. A sensor element outputs first detections responsive to a combined light comprising ambient light and the light output by the light source when the light source is on, and outputs second detections responsive to ambient light when the light source is off. The first detections are routed to a first accumulator to produce a first accumulation, and the second detections are routed to a second accumulator to produce a second accumulation. An adjusted output image is generated by removing a contribution of the second accumulation from the first accumulation.

Abstract: An imaging system includes a projector, a camera and a filter set of polarization filters. The projector is to project light onto a surface. The camera is to capture light reflected from the surface. The filter set is to remove light of a first polarization from the projected light and to remove light of a non-first polarization from the reflected light so that the camera detects only reflected light having the first polarization.

Abstract: An imaging system is disclosed. The imaging system has an image sensor and an illumination device. The imaging system captures two images, one with only ambient light, and the other with ambient light and light from the illumination device. The two images are synchronized such that the time between the start of the two image exposures is an integer multiple of at least one flicker period. The final image is created by subtracting the ambient only image from the other image.

Abstract: A passive transparent media adapter magnetically coupling to a scan system is disclosed. The transparent media adapter captures light from a concentrated light source in the scan module and transfers the light to backlight transparent media so that it can be imaged by the scanner module. The transparent media adapter has no active electronics or illumination so does not require control or power to operate. The magnetic coupling allows a significant amount of the concentrated light to be focused into a narrow backlight region that moves in sync with the scan module.

Abstract: A camera includes a light transmitter configured to transmit light pulses at a first rate, a light receiver configured to receive return signals corresponding to the light pulses transmitted by the light transmitter, and a sampler configured to sample electrical signals corresponding to the return signals received by the light receiver, wherein the sampler is configured to sample the electrical signals at a second rate that is lower than the first rate.

Abstract: A thin transparent media adapter is used when scanning transparent media on a contact image sensor or reduction optics scanner. The adapter uses illumination from a light guide assembly to illuminate a diffuser and the media. A lens assembly is used to focus the light from the media to create an intermediate image between the adapter and the scanner platen glass. The adapter is an optical assembly that forms an intermediate image of the transparent media in the object side focal plane of existing scanner optics. The existing scanner optics can then capture and focus the light from the intermediate image onto the scanner's existing sensor array. The adapter magnetically couples to the scan system to allow the lens array to follow movement of the optical system of the scanner.
