    Abstract: Image signal processing including generating image signal processing based encoding hints for motion estimation may include an image signal processor obtaining an input image portion of an input image from the input image signal, generating motion information for the input image portion, processing the input image portion based on the motion information, outputting processed image data, and outputting the motion information as encoding hints, such that the motion information is accessible by an encoder for generating an encoded output bitstream by obtaining the processed image data as source image data, obtaining the motion information, generating prediction data for encoding the source image data based on the motion information, generating encoded image data based on the prediction data, and including the encoded image data in an encoded output bitstream.

    Abstract: Systems and methods for utilizing on-camera sensor information to improve video and/or image encoding quality are discussed herein. Specifically, the systems and methods described herein may utilize on-camera sensor information to adaptively adjust an intra frame insertion rate associated with a sequence of frames. The intra frame insertion rate associated with a sequence of frames may be adjusted based on the motion of the image capturing device while capturing the sequence of frames and a predefined motion threshold associated with the intra frame insertion rate of the sequence of frames. In some implementations, the intra frame insertion rate may be adjusted based on the activity being performed during the capture of the sequence of frames. As such, the encoding of one or more frames within a sequence of frames may be adaptively adjusted to better suit the scene depicted by the sequence of frames.

    Abstract: Systems and methods are disclosed for image signal processing. For example, methods may include receiving, by an image signal processor, one or more input image signals from one or more image sensors; determining a mapping based on the input image signal(s), wherein the mapping includes records that associate image portions of an output image with corresponding image portions of the input image signal(s); sorting the records of the mapping according to an order of the corresponding image portions of the input image signal(s); applying, by the image signal processor, image processing to image portions of the input image signal(s) to determine image portions of one or more processed images in the order; and determining, by the image signal processor, the image portions of the output image based at least in part on the mapping and the corresponding image portions of the processed image(s) in the order.

    Abstract: Methods and apparatus for the stitching of images from a multi-camera array. In one embodiment, stitching is performed for a first image and a second image with an overlapping field of view by: encoding the first image to produce a first encoded image; encoding the second image to produce a second uncompressed encoded image; stitching the first image with the second image by: decoding the first encoded image to produce a decoded first image; storing the decoded first image in memory; accessing, by a stitching engine, the decoded first image from memory; accessing, by the stitching engine, the second uncompressed encoded image; stitching, by the stitching engine, the decoded first image with the accessed second uncompressed encoded image to produce a stitched image; and outputting, by the stitching engine, the stitched image.
