摘要

An editing apparatus and an editing method in a pen computing system using a whole display screen as an input window. Edited information written or drawn by a user on a transparent layer, which is displayed over original text, is stored as a picture or translated into computer-processible recognition data. Each transparent layer has a layer identifier. The user can display multiple layers over the original text by selecting layer identifiers to reflect layer information in a picture form or in a computer code form. The layer information, if demanded by the user, can be combined with the original text in order to generate edited text.
