A camera includes a lens carrier to which lens(es), defining an optical axis, are mounted. The lens carrier and the lens(es) are movable along the optical axis. The camera includes an autofocus (AF) damping structure for dampening motion of the lens carrier and the lens(es) in a direction along the optical axis. The camera includes a flexure platform having a dynamic platform to which an image sensor and a substrate are connected for movement together with the dynamic platform, a static platform connected to a static portion of the camera, and multiple flexure arms that mechanically connect the dynamic platform to the static platform. The camera includes electronic component(s) and a volume of space vertically aligned with the AF damping structure and extending from the AF damping structure to the substrate. The volume of space does not include a mounting location of the electronic component(s).

Flexure module component configurations for camera with moveable image sensor

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.

Biometric authentication techniques

An optoelectronic system includes a transmit side and a receive side. The transmit side and the receive side each include an oversampled phase locked loop configured to receive a decimated system clock signal. Each phase-locked loop is configured to output a high frequency sampling clock signal that, in the case of the transmit side, may be leveraged to generate an arbitrary current waveform that, in turn, can be delayed by a delay-locked loop before being applied to a current-controlled light emitting element. The receive side can generate a clock signal at the same high frequency as the transmit side and can be configured to trigger a reset of the transmit side so that the high frequency clock signals between the transmit and receive sides are synchronized.

A sensing device includes a first array of sensing elements, which output a signal indicative of a time of incidence of a single photon on the sensing element. A second array of processing circuits are coupled respectively to the sensing elements and comprise a gating generator, which variably sets a start time of the gating interval for each sensing element within each acquisition period, and a memory, which records the time of incidence of the single photon on each sensing element in each acquisition period. A controller sets, in each of at least some of the acquisition periods, different, respective gating intervals for different ones of the sensing elements.

Generating an image stream may include obtaining image data from a camera, identifying a first subset of the image data including a region of interest, identifying a second subset of the image data different than the first subset of the image data, processing the first subset of image data by a first processing pipeline to obtain a first processed set of image data, processing the second subset of image data by a second processing pipeline to obtain a second processed set of image data, wherein the second processing pipeline processes at a lower quality than the first processing pipeline, and combining the first processed set of image data and the second processed set of image data to obtain a processed image frame.

Foveated image capture for power efficient video see-through

Methods and apparatus for converting streaming media between different formats. A bridging device for e.g., Camera Serial Interface (CSI) and DisplayPort is disclosed. Both the CSI and DisplayPort technologies use low power mode operation during blanking intervals of a video transmission. However, the CSI interface can wake up in a very short amount of time (e.g., &#x2dc;400 ns), but the DisplayPort interface takes significantly longer to perform link training (e.g., &#x2dc;1 ms). Various embodiments of the present disclosure use frame signaling trigger to start a wait time interval timer; the wait time interval can be used by the bridge device to wake up the DisplayPort interface ahead of the CSI2 D-PHY interface, thereby ensuring that both links are active at the same time. This 'wake-up' technique can greatly reduce the size of buffering memories that are required.

A sensing device includes a first array of sensing elements, which output a signal indicative of a time of incidence of a single photon on the sensing element. A second array of processing circuits are coupled respectively to the sensing elements and comprise a gating generator, which variably sets a start time of the gating interval for each sensing element within each acquisition period, and a memory, which records the time of incidence of the single photon on each sensing element in each acquisition period. A controller controls the gating generator during a first sequence of the acquisition periods so as to sweep the gating interval over the acquisition periods and to identify a respective detection window for the sensing element, and during a second sequence of the acquisition periods, to fix the gating interval for each sensing element to coincide with the respective detection window.

A pixel in an image sensor can include a photodetector and a storage region disposed in one substrate, or a photodetector disposed in one substrate and a storage region in another substrate. A buried light shield is disposed between the photodetector and the storage region. A sense region, such as a floating diffusion, can be adjacent to the storage region, with the buried light shield disposed between the photodetector and the storage and sense regions. When the photodetector and the storage region are disposed in separate substrates, a vertical gate can be formed through the buried light shield and used to initiate the transfer of charge from the photodetector and the storage region. A transfer channel formed adjacent to, or around the vertical gate provides a channel for the charge to transfer from the photodetector to the storage region.

Devices and methods for adjusting an exposure window of a rolling shutter based on a frequency determined from ambient light gathered by a bimodal component are disclosed. Flickering light sources may cause artifacts in captured images, due to interplay between a period of a frequency of ambient light and the exposure window. An image capture device includes a semiconductor component configured to operate in two modes and an exposure window control component configured to compensate for the flickering based on a signal from the light source. In a sensor mode, the semiconductor component may operate to detect the frequency of ambient light. To avoid image artifacts, the frequency of the ambient light is analyzed and an exposure time is adjusted to an integer multiple of the period of the frequency such that exposure is matched to the periodic illumination of the flickering light source.

Flicker detection using semiconductor light source

In an embodiment, a host computing device includes an internal display and also includes a connector to connect to an external display. A cable is provided to connect to the connector and to connect to the external display. The cable includes video processing capabilities. For example, the cable may include a memory configured to store a frame buffer. The frame buffer may store a frame of video data for further processing by the video processing device in the cable. The video processing device may manipulate the frame in a variety of ways, e.g. scaling, rotating, gamma correction, dither correction, etc.

Cable with video processing capability

A semiconductor device includes a first substrate that has a sensing portion that detects predetermined information, a second substrate that has a first processing portion that processes data supplied thereto from the sensing portion, and a third substrate having a second processing portion that processes data supplied thereto either from the first substrate or from the second substrate.

Semiconductor device and sensing system

An image sensor includes pixels that accumulate charge during a first integration period and pixels that accumulate charge during shorter second integration periods when an image is captured. The pixels having the shorter second integration period accumulate charge at two or more different times during the first integration period. Charge is read out of the pixels associated with the first integration period at the end of the first integration period, while charge is read out of the pixels having the second integration period at the end of each second integration period.
