Abstract: A pixel includes a photosensor configured to photogenerate charge in response to incident light. A floating diffusion is configured to receive the charge photogenerated by the photosensor. A transfer transistor is coupled between the floating diffusion and the photosensor. A dual floating diffusion (DFD) transistor is coupled to the floating diffusion. A binning node is coupled to the DFD transistor. A floating diffusion interconnect grid is coupled to the binning node of the pixel and a binning node of a second pixel. The pixel and the second pixel are included in a pixel array. The DFD transistor is configured to couple the binning node to the floating diffusion when activated during a readout operation of the pixel array to provide a binned readout, and the DFD transistor is configured not to couple the binning node to the floating diffusion when deactivated to provide a full resolution readout.

Abstract: Methods for transmitting asynchronous event data via synchronous communications interfaces (and associated imaging systems) are disclosed herein. In one embodiment, an imager comprises an array of event vision pixels, and a synchronous communications transmitter configured to transmit frames of data to a synchronous communications receiver. The pixels generate event data based on activity within an external scene. The imager communicates, at a first time and to the receiver, an anticipated amount of data that will be included in a frame transmitted to the receiver at a second time. The anticipated amount of data can be based on a prediction of an amount of event data that will be generated at a future point in time for transmission to the receiver in the frame. The imager can then transmit the frame to the receiver at the second time with an amount of data corresponding to the anticipated amount of data.

Abstract: Multiple read image sensors, and associated methods for the same, are disclosed herein. In one embodiment, a method comprises reading out a reset level from a pixel to a corresponding sample and hold circuit; storing the reset level to a first storage device and to a second storage device of the sample and hold circuit; reading out a signal level from the pixel to the sample and hold circuit; and storing the signal level to a third storage device and to a fourth storage device of the sample and hold circuit. The reset level and the signal level can correspond to a same correlated double sampling of an image data signal captured by the pixel. The method can further include reading out the reset level from the first storage device; reading out the signal level from the third storage device; and recovering a first copy of the image data signal.

Abstract: A sensor includes a photodiode disposed in a semiconductor material to receive light and convert the light into charge, and a first floating diffusion coupled to the photodiode to receive the charge. A second floating diffusion is coupled to the photodiode to receive the charge, and a first transfer transistor is coupled to transfer the charge from the photodiode into the first floating diffusion. A second transfer transistor is coupled to transfer the charge from the photodiode into the second floating diffusion, and an inductor is coupled between a first gate terminal of the first transfer transistor and a second gate terminal of the second transfer transistor. The inductor, the first gate terminal, and the second gate terminal form a resonant circuit.

Abstract: A digital widescreen camera has an anamorphic lens focusing a field of view nearly twice as wide as tall on a photosensor array having nearly square aspect ratio. In embodiments, the photosensor array has an 8-pixel tiling unit organized as four pairs of adjacent left and right pixels, a first pair having two red-responsive pixels, a second pair having two blue-responsive pixels, and a third pair having two green-responsive pixels. In embodiments, signals from the 8-pixel tiling unit are processed into signals equivalent to signals from two adjacent Bayer-pattern 4-pixel tiling units. The corresponding method of digital photography includes receiving light through an anamorphic lens onto a photosensor array. In embodiments, the photosensor array has an eight-pixel tiling with four pairs of adjacent left and right pixels, a first pair with two red-responsive pixels, a second pair with two blue-responsive pixels, and a third pair with two green-responsive pixels.

Abstract: A display system includes a processor coupled to receive image data from an image source and a frame timing circuit. The processor is coupled to output the image data and first sync signals, where each one of the first sync signals is output after M number of pixel values of the image data are output from the processor. The frame timing circuit is coupled to the processor to receive the image data and the first sync signals. The frame timing circuit is coupled to output X number of pixel values of the image data and second sync signals to a display, where the X number of pixel values is an integer multiple of the M number of pixel values of the image data. Each one of the second sync signals is output after X number of pixel values of the image data are output from the frame timing circuit.
