Abstract: Systems and methods are disclosed for field of view adjustment for image capture devices. For example, methods may include receiving a field of view selection; oversampling, using an image sensor, to obtain an image at a capture resolution that is greater than an encode resolution; determining a crop setting based on the field of view selection; cropping the image using the crop setting to obtain a cropped image; down-scaling the cropped image to obtain a scaled image at the encode resolution; encoding the scaled image at the encode resolution; and storing, displaying, or transmitting an output image based on the scaled image.

Abstract: A device includes a processor that is configured to detect that a first image is captured by the device; configure the device to capture images in a first resolution after detecting that the first image was captured; start a timer; restart the timer when a second image is captured before the timer expires; detect an event indicative of a second resolution that is lower than the first resolution; and configure the device to capture images in the second resolution after detecting the event indicative of the second resolution.

Abstract: A method for a zero shutter-lag (ZSL) mode of an image capture device includes, in response to detecting a first event indicative of the ZSL mode, setting the image capture device to the ZSL mode. Setting the image capture device to the ZSL mode includes setting a sensor of the image capture device to a first resolution that is higher than a second resolution of a non-ZSL mode, and setting a timer to expire after a predefined period. The method also includes, in response to the timer expiring after the predefined period, setting the image capture device to the non-ZSL mode. The non-ZSL mode cancels the ZSL mode.

Abstract: Systems, apparatus, and methods for selectively parsing a live stream for a connected device. GoPro® cameras capture 2 video streams for every recording: a main resolution video (MRV) and a frame aligned low-resolution video (LRV). Currently, the LRV is streamed to other devices for playback in real-time. Unfortunately, not all devices in the mobile ecosystem can keep up with these transfer and playback speeds of the LRV; thus, exemplary embodiments of the present disclosure pick frames from the LRV to provide an IDR-only version that can be replayed with minimal processing burden. As a related issue, operating codecs in parallel at different resolutions can result in misaligned frame structures since each codec independently determines its “group of pictures” (GOP), etc. The described techniques define a frame correspondence that can also be used to improve post-processing at best effort.

Abstract: Processing of a burst of high dynamic range (HDR) images in a timely manner is described. The method includes receiving successive multi-exposure image sets from an image sensor, where a multi-exposure image set includes a short exposure image and long exposure image pair. The multiple short exposure image and long exposure image pairs in the successive multi-exposure image sets are processed via an image signal processor pipeline which includes Bayer noise reduction. The multiple short exposure image and long exposure image pairs are combined, using a HDR hardware component, to generate multiple HDR images, which are processed through local tone mapping and chroma noise reduction offline processing. General Purpose Raw (GPR) format images are generated for the multiple short exposure image and long exposure image pairs and stored for post-processing access.
