摘要： An image sensor having global shutter circuitry and an extremely fine pixel pitch. Disclosed image sensors combine global shutter circuitry with rolling shutter circuitry for respective subsets of sensor pixels to marry imaging benefits of global shutter circuitry with relatively small circuit overhead of rolling shutter circuitry. Such image sensors can achieve improved optical performance with smaller pixel pitch and optical resolution than existing global shutter image sensors.

摘要： Providing for operation of high-speed optical sensor equipment at full data path speeds in conjunction with testing equipment operating at a lower speed is described herein. By way of example, a data stream output from optical sensor equipment to testing equipment can be throttled at a serial interface between such equipment. Throttling can involve subdividing a set of pixel data and outputting a subset of the pixel data in a given readout frame. Consecutive outputs of respective subsets of pixel data are initiated with an offset from the previous readout frame. Accordingly, the optical sensor equipment can be operated at full speeds, simulating realistic operational conditions, while slower testing equipment can be utilized to perform data analytics, heuristics, and other quality tests on various portions of the optical sensor equipment.

摘要： Various technologies described herein pertain to controlling floating diffusion gain using a charge pump. Feedback can be utilized to control impedance of a floating diffusion region of a pixel of an image sensor, which further includes a read bus and an amplifier. The pixel includes a capacitor and a floating diffusion region, which has an intrinsic floating diffusion capacitance. The capacitor includes a first terminal and a second terminal, where the first terminal is coupled to the floating diffusion region. The amplifier includes an input terminal and an output terminal. The input terminal of the amplifier is coupled to the read bus and the output terminal of the amplifier is coupled to the second terminal of the capacitor. Gain of the amplifier is adjustable to control an equivalent capacitance of the floating diffusion region. Alteration of the equivalent capacitance can modify conversion gain and dynamic range of the pixel.

摘要： Various technologies described herein pertain to automatically adjusting the strength of a voltage booster of an image sensor. A self-scaled voltage booster includes a regulator, a controller, and two or more charge pumps that can be selectively enabled and disabled by the controller. The controller generates controller signals for the charge pumps based on a duty cycle of a regulator signal generated by the regulator. Moreover, the controller can maintain the controller signals without modification for at least a predetermined minimum period of time after a prior modification of at least one of the controller signals. Further, the controller can include a duty cycle and delay module (or a plurality of duty cycle and delay modules) that detects the duty cycle of the regulator signal and maintains the controller signals without modification for at least the predetermined minimum period of time.

摘要： Various technologies described herein pertain to defect pixel correction for image data collected by a pixel array of an image sensor. Neighborhood statistics for a given pixel from the image data are computed based on values of neighbor pixels of the given pixel from the image data. Whether the value of the given pixel is defective is detected based on the neighborhood statistics. The value of the given pixel is replaced when detected to be defective to output modified image data. Correction of the given pixel is a function of whether the given pixel is in a flat region or a non-flat region. When the given pixel is defective and in a non-flat region, a minimum edge across the given pixel is identified and the value of the given pixel is replaced with an average of values of neighbor pixels that belong to the minimum edge.
