    摘要: A method for decoding a 360-degree image includes: receiving a bitstream obtained by encoding a 360-degree image; generating a prediction image by making reference to syntax information obtained from the received bitstream; combining the generated prediction image with a residual image obtained by dequantizing and inverse-transforming the bitstream, so as to obtain a decoded image; and reconstructing the decoded image into a 360-degree image according to a projection format. Here, generating the prediction image includes: checking, from the syntax information, prediction mode accuracy for a current block to be decoded; determining whether the checked prediction mode accuracy corresponds to most probable mode (MPM) information obtained from the syntax information; and when the checked prediction mode accuracy does not correspond to the MPM information, reconfiguring the MPM information according to the prediction mode accuracy for the current block.

    摘要: In calibrating a motion picture film scanner, a calibration element is provided that is composed of a multi-step neutral gray series comprised of a plurality of known density patches, each corresponding to one or more prescribed aim voltages, that substantially represent the full density vs. exposure range of a photographic element. The calibration element is scanned with the motion picture film scanner and one or more signal voltages are generated for each density patch. The motion picture film scanner is then adjusted to bring the signal voltages toward the prescribed aim voltages, thereby generating one or more adjustments that compensate for errors from the prescribed aim voltages and capture substantially the full range of the motion picture film. Since each motion picture film that is scanned by the film scanner is a particular film stock, i.e., a particular film type, the calibration further includes applying a custom correction to the output of the motion picture film scanner for the particular film type being scanned. The custom correction may be a neutral scale correction provided by a one-dimensional look up table.

    摘要: A method for a 3:2 pull-down film source detection. First, a source is received. Then, field differences of two fields of the same type in the source and an average field difference according to the field difference corresponding to at least one prior field in the source are calculated. The source is established as a 3:2 pull-down film source by checking whether a 3:2 pull-down signature is in the source according to the field difference and the average field difference, and a bad editing point is detected according to an interlaced frame information of the source.
