Abstract: An apparatus for stitching together multiple camera images to form a blended image having an output projection format. The apparatus is configured to convert each of the multiple camera images into the output projection format. It is configured to stitch together the converted images to form a single image. It is also configured to output the single image as the blended image having the output projection format.

Abstract: A data packer forma bit stream for forwarding values to memory. The bit stream includes the values and respective prefixes for identifying the values and the data packer is configured to insert the prefixes at predetermined boundaries in the bit stream, such that a prefix for identifying one value is inserted between bits that define a value identified by a preceding prefix. A data unpacker unpacks a bit stream that comprises values and respective prefixes for identifying those values that are located at predetermined boundaries in the bit stream, such that a prefix for identifying one value is inserted between bits that define a value identified by a preceding prefix. The data unpacker identifies a prefix at a predetermined boundary in the bit stream and determine, in dependence on that prefix and the predetermined boundaries, a location of the next prefix in the bit stream.

Abstract: An image processing apparatus is provided that comprises an input configured to receive an image and a Laplacian generator configured to generate, from the image, a Laplacian pyramid that represents the image as a series of frames that contain different frequency components of the image. The image processing apparatus also comprises a compressor configured to compress the Laplacian pyramid for writing to memory.

Abstract: An apparatus for filtering multiple images so that they can be stitched together to form a blended image, the apparatus comprising a plurality of filters configured such that: (i) each filter is configured to process only images from the multiple images that will be non-overlapping with each other in the blended image; and (ii) images that will overlap with each other in the blended image are processed by different filters.

Abstract: An apparatus for combining multiple images to form a blended image, configured to identify regions of overlap: (i) in a first image and in a second image, corresponding to where those first and second images will overlap each other in the blended image; and (ii) in the first image and in a third image, corresponding to where those first and third images will overlap each other in the blended image, identify an image quality associated with each region of overlap, determine a gain for each image that, when applied to the image as a whole, will minimise a sum of: (i) a difference between the image qualities associated with the regions of overlap in the first and second images; and (ii) a difference between the image qualities associated with the regions of overlap in the first and third images and apply the respective gains to the first, second and third images.
