Image data processing apparatus and method

摘要

An image data processing apparatus generates output data representing an image in a spatial domain from a plurality of sets of input data, each representing in a spatial frequency domain a sub sampled version of the image in the spatial domain. An error detector detects any erroneous parts of the plurality of sets of input data in the spatial frequency domain. Each of the plurality of sets of input data is transformed from the spatial frequency domain into a sub sampled version of the image in the spatial domain. Any parts of the sub sampled versions that are dependent upon an erroneous part of a set of input data are interpolated from one or more spatially adjacent parts of one or more other sub sampled versions. The sub sampled versions are combined to form the output data.
