Abstract: Aspects relate to an image signal processor that processes frames at changing frame rates. An example method includes receiving, by an image signal processor, a first sequence of image frames from an image sensor at a first frame rate, processing each image frame of the first sequence of image frames at the first frame rate, and receiving from the image sensor an indication of a frame rate change from the first frame rate to a second frame rate. The method also includes configuring one or more filters of the image signal processor to process image frames from the image sensor in response to receiving the indication of the frame rate change from the image sensor, receiving a second sequence of image frames from the image sensor at the second frame rate, and processing each image frame of the second sequence of image frames at the second frame rate.

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.

Abstract: Methods and apparatus improve static region detection in an imaging pipeline. An imaging pipeline may perform detection of static regions of an image at multiple stages of the pipeline. For example, as static regions may be eliminated from further processing by the imaging pipeline, static region detection performed at an early stage of the pipeline may provide for maximized power savings. As images early in the pipeline may contain artifacts inhibiting detection of some static regions, additional static region detection may be performed after further image processing. For example, static region detection may be performed for a second time after some filtering is applied to images in the pipeline. Regions previously characterized as dynamic may be characterized as static later in the pipeline due to a reduction of noise for example provided by the filters, and differences between the static region detection at different positions within the imaging pipeline.
