Abstract: Methods, systems, and devices for techniques for phase detection autofocus (PDAF) are described. A device may receive a set of PDAF pixels and may rearrange the set of PDAF pixels into a first subset of pixels in a first line buffer and a second subset of pixels in a second line buffer. As part of a first output operation, the device may perform a uniformity correction on the first subset of pixels, output the first subset of pixels to a left, center, right (LCR) processing path, and write-back the corrected first subset of pixels to the first line buffer. As part of a second output operation, the device may perform a uniformity correction on the second subset of pixels, output the second subset of pixels to an LCR processing path and an interleaver, and pull the corrected first subset of pixels from the first line buffer to the interleaver.

Abstract: Techniques and systems are provided for processing image data. For example, an image signal processor can obtain (e.g., from a host processor) a first setting change indicator value indicating a change in parameter settings of the image signal processor. The image signal processor can obtain an image frame from an image sensor, and can determine a second setting change indicator value from the image frame. The second setting change indicator value can be provided to the image sensor from the host processor. The second setting change indicator value indicates a change in parameter settings of the image sensor. The image signal processor can compare the first setting change indicator value to the second setting change indicator value, and can determine whether to process the image frame or to drop the image frame based on comparing the first setting change indicator value to the second setting change indicator value.

Abstract: Methods, systems, and devices for image processing are described. A device may include a plurality of buffer components, each of which may receive a pixel lines that may each be associated with a respective raw image. An arbitration component of the device may combine at least some of the pixel lines into one or more data packets. The arbitration component may pass, using an arbitration scheme such as a time division multiplexing scheme, the one or more data packets from the arbitration component to a shared image signal processor (ISP) of the device. The shared ISP may generate a respective processed image based at least in part on the one or more data packets. In some examples, the device may maintain a respective set of image statistics, registers, and the like for at least some of the raw images.
