IMAGE PROCESSING APPARATUS CAPABLE OF REDUCING TIME REQUIRED TO UPDATE SOFTWARE, METHOD OF CONTROLLING THE SAME, INFORMATION PROCESSING SYSTEM, AND STORAGE MEDIUM

摘要

An image processing apparatus that localizes portions of software to be updated before performing software difference updating, to thereby make it possible to reduce time required for the update. The image processing apparatus receives update files from an update server on a network, and updates software based on the update files. The software is stored in a software storage area in a flash memory in a state divided into compressed files. The compressed files to be updated are decompressed out of the stored compressed files. The decompressed files are updated based on the update files received from the update server. The updated files are recompressed and stored in the software storage area.
