    Abstract: An optical proximity detector includes a plurality photodetectors (PDs) and a winner-take-all (WTA) circuit. Each of the PDs has a respective field of view (FOV) and produces a respective analog current detection signal indicative of light incident on and detected by the PD. In an embodiment, the WTA circuit includes a comparator and a multiplexor (MUX). The comparator compares the analog current detection signals produced by the PDs and produces a selection signal in dependence thereon. The MUX receives the analog current detection signals produced by the PDs and outputs one of the analog current detection signals in dependence on the selection signal produced by the comparator. Circuitry, which is shared by the PDs, produces a digital detection signal corresponding to the one of the analog current detection signals output by the MUX. Such design can be used to reduce power consumption, size and cost of an optical proximity detector.

  • Patent number: 9131223
    Abstract: A system includes a camera and a projector for capturing spatial detail having resolution exceeding that afforded by the imaging optics, and recovering topographic information lost to the projective nature of imaging. The projector projects a spatial pattern onto the scene to be captured. The spatial patterns may include any pattern or combination of patterns that result in complex sinusoidal modulation. Spatial detail such as texture on the objects in the scene modulate the amplitude of the spatial pattern, and produce Moiré fringes that shifts previously unresolved spatial frequencies into the camera's optical passband. The images may be demodulated, and the demodulated components may be combined with the un-modulated components. The resulting image has spatial detail previously inaccessible to the camera owing to the band-limited nature of the camera optics. A spatial pattern may also be projected and received by the camera to estimate topographic information about the scene.

  • Patent number: 8988745
    Abstract: An image processing apparatus of the present invention acquires a photographed image of an object on which indicators have been arranged, detects the indicators from the photographed image with use of a comparison reference image for pattern matching prepared in advance, and instructs to perform predetermined processing based on the detected indicators. The indicators each have a pattern where influence of geometrical image distortion generated corresponding to a photographing distance or a photographing angle with respect to the object is restrained by a central portion of the photographed image, and the comparison reference image is a partial image corresponding to a central portion of the indicator. The indicators are detected from the photographed image by comparing the comparison reference image with the acquired photographed image.

  • Patent number: 8982436
    Abstract: A carriage motor which is a heat generating device is arranged next to a CIS in a scanner unit. The carriage motor drives respective transport rollers of an ADF unit via a gear system as well. The scanner unit makes a white reference board be read so as to obtain white reference data, and obtains black reference data more frequently than the white reference data, e.g., in a continuous process for reading a document. As a CIS module continues a reading process, the black reference data changes as being affected by a change in temperature in the CIS module, etc. The scanner unit deals with such a change in the black reference data by obtaining the black reference data more frequently.
