Patent number: 11914078Abstract: Imaging apparatus (22) includes a radiation source (40), which emits pulsed beams (42) of optical radiation toward a target scene (24). An array (52) of sensing elements (78) output signals indicative of respective times of incidence of photons in a first image of the target scene that is formed on the array of sensing elements. An image sensor (64) captures a second image of the target scene in registration with the first image. Processing and control circuitry (56, 58) identifies, responsively to the signals, areas of the array on which the pulses of optical radiation reflected from corresponding regions of the target scene are incident, and processes the signals from the sensing elements in the identified areas in order measure depth coordinates of the corresponding regions of the target scene based on the times of incidence, while identifying, responsively to the second image, one or more of the regions of the target scene as no-depth regions.Type: GrantFiled: September 2, 2019Date of Patent: February 27, 2024Assignee: APPLE INC.Inventors: David Silver, Moshe Laifenfeld, Tal Kaitz

Patent number: 11868455Abstract: Techniques are disclosed relating to biometric authentication, e.g., facial recognition. In some embodiments, a device is configured to verify that image data from a camera unit exhibits a pseudo-random sequence of image capture modes and/or a probing pattern of illumination points (e.g., from lasers in a depth capture mode) before authenticating a user based on recognizing a face in the image data. In some embodiments, a secure circuit may control verification of the sequence and/or the probing pattern. In some embodiments, the secure circuit may verify frame numbers, signatures, and/or nonce values for captured image information. In some embodiments, a device may implement one or more lockout procedures in response to biometric authentication failures. The disclosed techniques may reduce or eliminate the effectiveness of spoofing and/or replay attacks, in some embodiments.Type: GrantFiled: February 22, 2021Date of Patent: January 9, 2024Assignee: Apple Inc.Inventors: Deepti S.

Publication number: 20220364849Abstract: Depth mapping apparatus includes an illumination assembly, which directs modulated optical radiation toward a target scene, and a camera, which captures a two-dimensional image of the target scene. A range sensor senses respective times of flight of photons reflected from a matrix of locations disposed across the target scene. A processor derives first depth coordinates of the matrix of locations responsively to the respective times of flight, derives second depth coordinates of the matrix of locations responsively to a transverse disparity between features in the two-dimensional image and corresponding reference features in a reference image, computes a disparity correction function based on a difference between the first and the second depth coordinates at the matrix of locations, corrects the transverse disparity between the two-dimensional image and the reference image using the disparity correction function, and generates a depth map of the target scene based on the corrected transverse disparity.Type: ApplicationFiled: March 8, 2022Publication date: November 17, 2022Inventors: Shay Yosub, Assaf Avraham, Jawad Nawasra, Jonathan Pokrass, Moshe Laifenfeld, Nir Ben Zadok, Niv Gilboa, Tal Kaitz, Ronen Akerman, Naveh Levanon

Patent number: 10962628Abstract: Disclosed are devices and methods for scanning sensing systems having an array of light sensing pixels, such as pixels that use single-photon avalanche diodes. Light pulses are emitted into a field of view (FOV) at starts of a sequence of time intervals, and a weighted tabulation of the times-of-flight of the reflected light pulses within each time interval is used to detect an object in the FOV and determine its distance. Each weight is based on the time-of-flight between the emitted pulse and the received reflected light pulse and on the number of the emitted light pulse in the sequence of emitted light pulses. For near objects the weights emphasize times-of-flight from peripheral time intervals of the sequence; for far objects the weights emphasize central time intervals of the sequence.Type: GrantFiled: January 25, 2018Date of Patent: March 30, 2021Assignee: Apple Inc.Inventors: Moshe Laifenfeld, Tal Kaitz, Shingo Mandai, Cristiano L.

Patent number: 7925295Abstract: A method and devices are provided to allow reducing interferences occurring in adjacent wireless communication networks. When a subscriber device experiences interferences resulting from the operation of an adjacent wireless network, it transmits an adjustment signal which serves as a request for adjustment, to the base station operative at the adjacent wireless communication network. The adjacent base station that receives the adjustment signal retrieves adjustment information therefrom, and based on the retrieved information will determine whether it should effect a change in its transmission that would result in reducing the interferences experienced at the subscriber device sending the adjustment signal.Type: GrantFiled: April 13, 2005Date of Patent: April 12, 2011Assignee: Alvarion Ltd.Inventors: Vladimir Yanover, Tal Kaitz, Naftali Chayat
