Abstract
More efficient encoding/decoding in decomposing and recomposing a high resolution image is obtained by employing a unique prediction arrangement. The prediction arrangement determines whether high resolution pixels to be recomposed from low resolution pixels from a low resolution replica of the high resolution are so-called typically predictable or non-typically predictable by using general prediction rules. The general prediction rules are also employed to determine if any of the typically predictable high resolution pixels would be improperly recomposed. Such high resolution pixels which would be improperly recompased are identified as exceptions. It is noted that so-called supplemental information is required to properly recompose non-typically predictable pixels and typically predictable pixels which are identified as exceptions. To this end, exceptions accompany the low resolution pixel for which the corresponding high resolution pixels would otherwise be improperly recomposed.
