Abstract:
1. A reproducing apparatus comprising: a reproducing unit which reproduces image data including a plurality of blocks each having a plurality of samples including a first sample and a second sample which are adjacent to each other in a horizontal direction, from a recording medium; an error detecting unit which detects an error in each of the first sample and the second sample included in the respective blocks of the image data reproduced by the reproducing unit; a discrimination unit which discriminates whether a difference between two samples adjacent to each other in the horizontal direction of the image data reproduced by the reproducing unit is greater than a predetermined value; an interpolation unit which interpolates the erroneous block detected in the image data reproduced by the reproducing unit in accordance with a discrimination result of the discrimination unit if the error detecting unit detects that the error occurs in the erroneous block in such a manner that an error occurs in the first sample included therein but no error occurs in the second sample included in the same block, the interpolation unit replaces both the first sample and the second sample of the erroneous block with samples of the block adjacent to the erroneous block in a vertical direction if the discrimination unit discriminates that the difference is greater than the predetermined value, and replaces the first sample of the erroneous block with the second sample of the same block if the discrimination unit discriminates that the difference is not greater than the predetermined value.
