Abstract
A communication apparatus dividing an image for one field into a plurality of groups each including N lines (N≧1) and performing compression/decompression for each group includes a separator separating image data from reception data; a determination unit determining whether an error exists in the separated image data; a storage unit storing the image data as interpolation data when the determination unit determines that no error exists in the image data; a decoder decoding the image data; a first detection unit detecting a decoding position of the image data and a corresponding position of the interpolation data stored in the storage unit when the determination unit determines that an error exists in the image data and that the amount of missing data of the image data exceeds a threshold; and a reading unit reading the interpolation data in accordance with the detected decoding position and corresponding position.
