Abstract: Various examples are directed to systems, devices, and methods effective to generate updated pixel values in a stitched image. A processor may be programmed to identify a first block of pixels located in a region of a stitched image. The region may include pixels representing parallax views of a portion of a physical environment. The processor may determine a first average pixel value of pixels of the first block. The processor may identify a second block of pixels in the region. The processor may determine a second average pixel value of pixels of the second block. The processor may generate an updated pixel value for a pixel location of the first block or the second block. The updated pixel value may be based at least in part on the first average pixel value and the second average pixel value.

Abstract: Various examples are directed to a panoramic camera system comprising a first image sensor, a second image sensor and an enclosure. The first image sensor may have a first in-air field-of-view and the second image sensor may have a second in-air field-of-view. The first in-air field-of-view may overlap the second in-air field-of-view by greater than a threshold amount. The enclosure may comprise a curved outer surface. An alternate medium field-of-view of the first image sensor may overlap an alternate medium field-of-view of the second image sensor by greater than the threshold amount. The panoramic camera system may also comprise an image processor that is programmed to determine that the first image sensor and the second image sensor are within the enclosure. The panoramic camera system may stitch frames captured by the first and second image sensors considering an alternate medium stitching parameter.

Abstract: Various examples are directed to systems and methods for formatting stitched panoramic frames for transmission to a remote image processing system, the method comprising. A control circuit of a panoramic camera may receive first and second frames captured by first and second image sensors having partially overlapping fields-of-view. The control circuit may identify a first overlap region of the first frame and a second overlap region of the second frame. The first and second overlap region may comprise pixel values from portions of the fields-of-view of the image sensors that overlap. The control circuit may generate a panoramic frame from based at least in part on the first and second frames. The control circuit may generate a transmission frame comprising the panoramic frame, the first overlap region and the second overlap region.
