Abstract: An image capture device, pixel, and method of determining a focus setting for an image capture device are described. The image capture device includes an imaging area and a pixel readout circuit. The imaging area includes a plurality of pixels. The plurality of pixels includes multiple pixels in which each pixel of the multiple pixels includes a two-dimensional array of photodetectors and a microlens. Each photodetector in the array of photodetectors for a pixel is electrically isolated from each other photodetector in the array of photodetectors. A microlens is disposed over the array of photodetectors for the pixel. The pixel readout circuit includes, per pixel, a shared readout circuit associated with the array of photodetectors for the pixel and a set of charge transfer transistors. Each charge transfer transistor is operable to connect a photodetector in the array of photodetectors to the shared readout circuit.

Abstract: Embodiments are disclosed for a Phase Detection Autofocus (PDAF) pixel, including a photodiode; a color filter disposed on the photodiode; and a parabolic-shaped microlens disposed on the color filter and oriented in a direction that generates an angular response, such that a phase disparity signal is generated in a horizontal or vertical direction of an imaging plane or both directions.
