Abstract
Disclosed is an apparatus for processing images with which, when bit streams of images subjected to the MPEG coding in the form of open GOP are joined to each other, image quality is prevented from deteriorating at the joint between the bit streams. In the apparatus for processing images, when a bit stream Y is inserted in a bit stream X, before-I-picture B-pictures (B-pictures appearing before an I-picture is displayed) which are part of images forming first one of GOP's in the bit stream Y are deleted. Temporal references of the remaining images forming the first GOP are then changed. The before-I-picture B-pictures, which are otherwise predicted by using one of images forming the last GOP of the bit stream X, are not longer displayed.
