An apparatus and method creating a ghost-free High Dynamic Range Image (HDRI) based on filtering are provided. It is possible to effectively prevent a ghost phenomenon from occurring when a single HDRI is created from a plurality of LDRIs, by defining a ghost area using a probability based on a global transfer function indicating a relationship for intensities of several frames, rather than searching for or identifying a ghost area in a single or each image.

A distributed video encoder and decoder and a distributed video encoding and decoding method through a symmetrical motion prediction and channel division are provided. Side information may be generated through the symmetrical motion prediction, and only a portion, which is significantly distorted, may be encoded and decoded into a channel code through an evaluation of the side information and thus, a configuration of the distributed video decoder may be simplified.
