    Abstract: Various implementations disclosed herein include devices, systems, and methods that determine a control signal before synchronous readout of a frame (or part of the frame) is performed by a sensor. Various implementations disclosed herein include devices, systems, and methods that determine event density (e.g., a dense row signal or a dense frame signal) before synchronous readout is performed by the sensor. In some implementations, the event camera is capable of operating in a first readout mode and a second readout mode based on a number of events. In the second readout mode, less data per pixel may be readout.

    Abstract: An imaging device includes an image sensor and an image processor. The image sensor includes an array of pixels. At least one pixel in the array of pixels includes an array of phase disparity subpixels. The array of pixels includes a set of filter elements arranged in a filter pattern, with different subsets of pixels receiving light through different types of filter elements in the set of filter elements. The image processor is configured to receive values measured by at least the phase disparity subpixels; estimate phase disparities between the received values; generate, using the estimated phase disparities, a set of corrected values for the phase disparity subpixels; and generate, using the set of corrected values for the phase disparity subpixels, a set of demosaiced values for each image plane in a set of image planes. Each image plane is associated with a different type of filter element in the set of filter elements.

    Abstract: Various implementations disclosed herein include devices, systems, and methods that buffer events in device memory during synchronous readout of a plurality of frames by a sensor. Various implementations disclosed herein include devices, systems, and methods that disable a sensor communication link until the buffered events are sufficient for transmission by the sensor. In some implementations, the sensor using a synchronous readout may select a readout mode for one or more frames based on how many of the pixels are detecting events. In some implementations, a first mode that reads out only data for a low percentage of pixels that have events uses the device memory and a second mode bypasses the device memory based on accumulation criteria such as high percentage of pixels detecting events. In the second mode, less data per pixel may be readout.
