  • Patent number: 11108980
    Abstract: A semiconductor device may include an array of single-photon avalanche diode pixels. The single-photon avalanche diode (SPAD) pixels may include a SPAD coupled to a supply voltage terminal via first and second reset paths. The first reset path may be a fast reset path that provides the SPAD with a short recovery time. The second reset path may be a slower reset path that provides the SPAD with a longer recovery time, but is used to ensure the SPAD is quenched even when the quench resistance associated with the first reset path is low. Logic circuitry may selectively activate the first or the second resets to quench and reset the SPAD. A SPAD pixel may also include one or more switches that keep nodes in the SPAD pixel at a constant voltage when the SPAD pixel is inactive.

    Abstract: In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products for detecting motion in images. A computing system receives first and second images that were captured by a camera. The computing system generates, using the images, a mathematical transformation that indicates movement of the camera from the first image to the second image. The computing system generates, using the first image and the mathematical transformation, a modified version of the first image that presents the scene that was captured by the first image from a position of the camera when the second image was captured. The computing system determines a portion of the first image or second image at which a position of an object in the scene moved, by comparing the modified version of the first image to the second image.

  • Patent number: 9948905
    Abstract: A remote access control system comprising a remote host connected to a mobile device, a proximity sensor doorbell, a door lock device and a gateway device is provided. The proximity sensor doorbell triggers a doorbell signal when sensing a finger of a visitor approaches. The gateway device sends a first notification message to the mobile device via the remote host when recognizing that a captured monitoring video comprises image of the visitor, sends a second notification message to the mobile device via the remote host when receiving the doorbell signal, and controls the door lock device to unlock when receiving an unlocking message from the mobile device. This system facilitates the householder to control the entry remotely and effectively reduces the probability of doorbell failing.

  • Patent number: 9818180
    Abstract: It is possible to determine whether or not a specific shape candidate obtained from a captured standard image has a corresponding shape in an actual space. A shape surrounded by straight lines is detected from a standard image as a candidate having a rectangular shape. A target object image obtained by imaging a target object representing the candidate having the rectangular shape at a viewing angle different from the viewing angle of the standard image is generated. The generated target object image is detected from a reference image obtained by imaging the target object at a different viewing angle. If the target object image is detected, the target object represented by the candidate having the rectangular shape is determined to be a rectangle.

  • Patent number: 9760436
    Abstract: Apparatuses and methods for data storage error protection are described. One example apparatus for data storage error protection includes an array of memory cells arranged in a first dimension and a second dimension. A controller is configured to determine a set of symbols corresponding to data stored in the memory cells. The controller is configured to add subsets of the set of symbols obliquely oriented to the first dimension and the second dimension to determine a number of parity check symbols. The controller is configured to use a same number of parity check symbols for protection of a first subset of memory cells oriented parallel to the first dimension as used for protection of a second subset of memory cells oriented parallel to the second dimension.

  • Patent number: 9196048
    Abstract: An autonomous pavement assessment system may receive depth data indicative of the depth of pixels that collectively comprise multiple defective areas of pavement. For each defective area, the system may fit a plane to it; generate a histogram that indicates the frequency of its pixels at different depths; dynamically determine a depth noise threshold for it; generate a binary image of it based on its noise threshold; and generate a depth map of it containing only the pixels that have a depth that meets or exceeds its depth noise threshold. The system may prioritize the multiple defective areas for repair and/or generate optimized rehabilitation routes. Crowd sourcing may be used to gather the depth data, as well as location information for each defective area.

  • Patent number: 9142031
    Abstract: An image processing apparatus that is capable of improving the alignment accuracy by detecting a motion vector accurately even if there is a low contrast region or a repeating pattern region. A division unit divides each of inputted images into blocks of a predetermined size. A first determination unit determines whether contrast in a block is less than a predetermined contrast for each of the blocks. A size changing unit changes the size of the block concerned when the first determination unit determines that the block concerned is low contrast. A motion vector detection unit detects a motion vector by comparing images in each pair of corresponding blocks between the images.

    Abstract: An image processing apparatus (10) includes: an imaging device (20); an optical system (22); and a distance determining unit (16) determining an object distance between the optical system and the object based on a size of a blur developed on the image. The optical system (22) has a characteristic which simultaneously satisfies both of conditions that (i) variation in magnification is equal to or smaller than the predetermined number of pixels in the case where a focused point is set farthest from and closest to the optical system (22) in a range of the distance of the object determined by the distance determining unit (16) and (ii) variation in a PSF due to an image height of the optical system (22) is equal to or smaller than a predetermined degree so as not to affect the determination of the distance of the object by the distance determining unit (16).
