Abstract: In a system for coding high dynamic range (HDR) images using lower-dynamic range (LDR) images, a reshaping function allows for a more efficient distribution of the codewords in the lower dynamic range images for improved compression. A trim pass of the LDR images by a colorist may satisfy a director's intent for a given “look,” but may also result in unpleasant clipping artifacts in the reconstructed HDR images. Given an original forward reshaping function which maps HDR luminance values to LDR pixel values, a processor identifies areas of potential clipping and generates modified forward and backward reshaping functions to reduce the visibility of potential artifacts from the trim pass process while preserving the director's intent.

Abstract: A method of encoding a video stream comprising receiving a frame of a video stream to be encoded, performing motion detection in the frame to identify steady regions, and temporally filtering the frame so as to provide temporally filtered pixel values. For a pixel in the steady regions of the frame, the temporally filtered pixel value is used when encoding the pixel, on a condition that the pixel belongs to a block of pixels of the frame that will be intra-coded. On a condition that the pixel instead belongs to a block of pixels of the frame that will be inter-coded, a value that was used when encoding a corresponding pixel of the immediately preceding frame is used when encoding the pixel.

Abstract: Example apparatus and methods produce image correction data for a lens or sensor based on individual images acquired under different operating parameters. Example apparatus and methods then produce strip correction data based on a strip of images pieced together from the individual images. Example apparatus and methods then produce panoramic image correction data based on a panoramic image pieced together from two or more strips of images. The strip of images is produced without using a hemispherical mirror and thus accounts more accurately for issues associated with making a two dimensional representation of a three dimensional spherical volume. Images are acquired using different imaging parameters (e.g., focal length, pan position, tilt position) under different imaging conditions (e.g., temperature, humidity, atmospheric pressure, pan rate, tilt rate) to account for aberrations that may appear or be exacerbated under operating conditions.

Abstract: Movements of a pan and tilt camera may be controlled by generating preview images of the view obtained by the camera in a particular direction. A camera may periodically scan its environment by moving through its range of motion and capturing a series of frames that can be stitched together. The resulting preview image may be a panoramic or spherical representation of the camera's possible viewpoints and may be displayed on a user interface for controlling the camera remotely. A live video from the camera may be displayed, and when a request to move a viewing angle of the camera is displayed, a corresponding portion of the preview image for the new viewing angle is displayed until a live video of the camera for the new viewing angle is available.
