Abstract: A pair of cameras having an overlapping field of view is aligned based on images captured by image sensors of the pair of cameras. A pixel shift is identified between the images. Based on the identified pixel shift, a calibration is applied to one or both of the pair of cameras. To determine the pixel shift, the camera applies correlation methods including edge matching. Calibrating the pair of cameras may include adjusting a read window on an image sensor. The pixel shift can also be used to determine a time lag, which can be used to synchronize subsequent image captures.

Abstract: Apparatus and methods for providing a frame packing arrangement for the encoding/decoding of, for example, panoramic content. In one embodiment, the frame packing arrangement utilizes overlapping imaging data so as to enable, for example, a post-decode stitching operation to be performed. The frame packing arrangement may utilize a number of projection formats, such as a cubemap projection, and may utilize any number of differing aspect ratios such as, without limitation, 4×3, 3×2, 4×2, 2×4 aspect ratios. Additionally, the overlapping imaging data may be positioned within the frame packing arrangement chosen so as to improve upon coding efficiency. For example, the overlapping imaging data may be positioned within the frame packing arrangement so as to emphasize image continuity. An encoder apparatus and decoder apparatus for use with the aforementioned frame packing arrangements are also disclosed.

Abstract: A camera system includes a camera and an underwater housing. The underwater housing, when submerged underwater, causes refraction of light entering the camera, thereby affecting focus. The camera includes a lens assembly adjustable between a first secured position at a first distance from an image sensor to enable the camera to capture images that are in focus when the camera is outside of water. The lens assembly is adjustable to a second secured position at a second distance from the image sensor to enable the camera to capture images that are in focus when the camera operates within the underwater housing and submerged under water.

Abstract: Apparatus and methods for the stitch zone calculation of a generated projection of a spherical image. In one embodiment, a computing device is disclosed which includes logic configured to: obtain a plurality of images; map the plurality of images onto a spherical image; re-orient the spherical image in accordance with a desired stitch line and a desired projection for the desired stitch line; and map the spherical image to the desired projection having the desired stitch line. In a variant, the desired stitch line is mapped onto an optimal stitch zone, the optimal stitch zone characterized as a set of points that defines a single line on the desired projection in which the set of points along the desired projection lie closest to the spherical image in a mean square sense.

Abstract: Multiple cameras are arranged in an array at a pitch, roll, and yaw that allow the cameras to have adjacent fields of view such that each camera is pointed inward relative to the array. The read window of an image sensor of each camera in a multi-camera array can be adjusted to minimize the overlap between adjacent fields of view, to maximize the correlation within the overlapping portions of the fields of view, and to correct for manufacturing and assembly tolerances. Images from cameras in a multi-camera array with adjacent fields of view can be manipulated using low-power warping and cropping techniques, and can be taped together to form a final image.

Abstract: A method and system are described. The method includes capturing a set of images from an array of cameras, each camera of the array of cameras having an overlapping field of view (FOV) with an adjacent camera of the array of cameras. The method further includes synchronously capturing a supplemental image from an additional camera, the additional camera having an at least partially overlapping FOV with every camera of the array of cameras. Supplemental information is extracted by comparing the supplemental image with the set of images. Portions of the set of images are stitched based in part on the supplemental information to produce a combined stitched image, the combined stitched image having a higher resolution than each image of the set of images.

Abstract: An underwater housing comprises a laterally offset back-to-back dome configuration. A dual-lens camera having laterally offset back-to-back lenses is mounted within the housing such that the optical axes of the camera lenses align with the optical axes of the domes. This configuration beneficially minimizes effects introduced by the dome on field of view and focus.

Abstract: A system captures a first hemispherical image and a second hemispherical image, each hemispherical image including an overlap portion, the overlap portion capturing a same field of view, the two hemispherical images collectively comprising a spherical FOV and separated along a longitudinal plane. The system maps a modified first hemispherical image to a first portion of the 2D projection of a cubic image, the modified first hemispherical image including a non-overlap portion of the first hemispherical image, and maps a modified second hemispherical image to a second portion of the 2D projection of the cubic image, the modified second hemispherical image also including a non-overlap portion. The system maps the overlap portions of the first hemispherical image and the second hemispherical image to the 2D projection of the cubic image, and encodes the 2D projection of the cubic image to generate an encoded image representative of the spherical FOV.
