Abstract: An exemplary camera calibration apparatus includes a movable, e.g., rotatable, support structure which is controllably positioned to allow for image capture of different test patterns and image capture of the same pattern at different distances by a mounted camera. A first test pattern is mounted on a wall, e.g., a pyramid shaped 4 sided wall formed by panels surrounding the camera under calibration. The movable support structure has a first mirror attached to a first side and has a second test pattern attached to a second side. A second mirror mounted on an internal sidewall of the calibration apparatus housing facilities a different image path distance between the camera capturing the image of the first test pattern and the first test pattern. The exemplary camera calibration apparatus is well suited for efficiently calibrating camera devices including a plurality of camera modules, e.g., optical chains, in a relatively small area.

Abstract: A chrominance filter for excluding certain pixels from being included in a white balance calculation. By comparing a target pixel to predetermined maximum values of blue, red, magenta and green, a chrominance filter can selectively include pixels in the white balance correction calculation.

Abstract: Data object management for a range of memory. The range of memory has first and second opposite ends. A plurality of data objects are written to a first contiguous region of memory located at the first end of the range of memory. At least one of the valid data objects of the plurality of data objects are copied to a second contiguous region of memory located at the second end of the range of memory when a reclamation process is requested. The valid data objects copied from the first contiguous region of memory are marked as invalid data in the first contiguous region of memory subsequent to the valid data objects being copied to the second end of the range of memory, and the memory in which invalid data objects in the first contiguous region of memory are located is erased.
