Abstract: 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.
Abstract translation: 公开了一种用于根据由双模组件聚集的环境光确定的频率来调节卷帘的曝光窗的装置和方法。 由于环境光的频率周期与曝光窗口之间的相互作用，闪烁的光源可能在捕获的图像中造成伪像。 图像捕获装置包括被配置为以两种模式操作的半导体部件和被配置为基于来自光源的信号来补偿闪烁的曝光窗控制部件。 在传感器模式中，半导体部件可以操作以检测环境光的频率。 为了避免图像伪影，分析环境光的频率，并且将曝光时间调整到频率周期的整数倍，使得曝光与闪烁光源的周期性照明相匹配。

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: A pixel (700) in an image sensor can include a photodetector (708) and a storage region (712) disposed in one substrate, or a photodetector disposed in one substrate (738) and a storage region in another substrate (740). A buried light shield (710) is disposed between the photodetector and the storage region. A sense region (716), 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 (714) 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 (744) formed adjacent to, or around the vertical gate provides a channel for the charge to transfer from the photodetector to the storage region.

Abstract: A method of operating an image sensor. Charge accumulated in a photodiode during a first sub-exposure may be selectively stored in a storage node responsive to a first control signal. Charge accumulated in the photodiode during a first reset period may be selectively discarded responsive to a second control signal. Charge accumulated in the photodiode during a second sub-exposure may be selectively stored responsive to the first control signal. Charge stored in the storage node from the first and second sub-exposures may be transferred to a floating diffusion node responsive to a third control signal.
