Abstract: Various embodiments disclosed herein include techniques for determining autofocus for a camera on a mobile device. In some instances, depth imaging is used to assist in determining a focus position for the camera through an autofocus process. For example, a determination of depth may be used to determine a focus position for the camera. In another example, the determination of depth may be used to assist another autofocus process.

Abstract: The sensitivity of one or more single-photon avalanche diodes (SPAD) in a SPAD detector is modulated over time. The sensitivity of all of the SPADs may be modulated, or the sensitivity of one section of the SPADs can be modulated differently from another section of the SPADs. Various techniques for modulating the sensitivity are disclosed.

Abstract: 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.

Abstract: Depth sensing apparatus (20) includes a radiation source (21), which is configured to emit a first plurality of beams (30) of light pulses toward a target scene (32). An array (24) of a second plurality of sensing elements (78) is configured to output signals indicative of respective times of incidence of photons on the sensing element, wherein the second plurality exceeds the first plurality. Light collection optics (34) are configured to image the target scene onto the array of sensing elements. Processing and control circuitry (26, 28, 35) is coupled to receive the signals from the array and is configured to search over the sensing elements in order to identify, responsively to the signals, respective regions of the array on which the light pulses reflected from the target scene are incident, and to process the signals from the identified regions in order determine respective times of arrival of the light pulses.

Abstract: Disclosed herein are methods and devices for light emitting depth sensors such as scanning depth sensors and LIDARS. Methods, devices and systems disclose tracking a beam of reflected light pulses on an array of light sensing pixels. The tracking can dynamically update a location of the beam or an expected on-center time of the reflected light pulses at a pixel of the array. Counts of detected reflected pulses in time periods before and after the expected on-center time at a pixel are used to detect offsets in initial estimates of the beam location or timing.

Abstract: An electro-optical device (20) includes a laser (28), which is configured to emit toward a scene (38) pulses (36) of optical radiation. An array (34) of detectors (79) are configured to receive the optical radiation that is reflected from points in the scene and to output signals indicative of respective times of arrival of the received radiation. A controller (26) is coupled to drive the laser to emit a sequence of pulses of the optical radiation toward each of a plurality of points in the scene and to find respective times of flight for the points responsively to the output signals, while controlling a power of the pulses emitted by the laser by counting a number of the detectors outputting the signals in response to each pulse, and reducing the power of a subsequent pulse in the sequence when the number is greater than a predefined threshold.
