2006-10-01 Implementation
This standard is modified to adopt ISO12651:1999 Electronic imaging vocabulary (English version) The main differences between this standard and ISO12651:1999 are as follows: - The foreword of ISO12651:1999 has been deleted, and the foreword of this standard has been rewritten; - The table of contents in ISO12651:1999 has been deleted, and GB/T 20225—2006
-In addition to some contents in Chapter 3 of IS012651:1999 \"Guidelines to be followed\", the contents on explaining terminology and data expression methods are written into the preface;
-This standard lists \"Terms and definitions\" in Chapter 3; a term index is set up, which is divided into a Chinese phonetic index and an English corresponding word index. References: Other terms used in this standard, such as \"vocabulary\" "terms\" and \"definition\", adopt the meanings defined in GB/T 15237-1994 \"Basic Vocabulary of Technical Training\";
The normative references GB/115237.1-2000 (9V1S01087-1:2000) is cited in the documents, replacing the old standard JSO10871990; GB/T 2659:2000, (eqv 1S0 3166-1:1997), replacing 1S0 3166-1:1997. This standard was proposed and coordinated by the National Technical Committee for Standardization of Document Imaging Technology (SAC/TC86). This standard was drafted by the National Technical Committee for Standardization of Document Imaging Technology. The main drafters of this part are Xiao Jianping and Xu Zhouya. GB/T20225—2006
The development of imaging technology has promoted the international exchange of entities and information. Due to the diversity of a large number of professional terms in different fields or different expressions of the same concept in different languages, as well as the lack of definition or inaccurate definition of useful concepts, this communication often becomes very difficult. ||tt ||To avoid misunderstandings and facilitate communication, it is important to clarify concepts so that terms can represent the same concept in different languages ​​or in different countries, and that various terms have equivalent definitions in different languages. The purpose of this standard is to provide strict, concise definitions that can be understood by all relevant parties. The definition of each concept should be selected to be suitable for general use. In some specific application environments, the definition may need to be further refined. Although this standard can maintain its own consistency, readers should still pay attention to the flexibility of language, standardization of terms, and consistency issues, which may lead to duplication and inconsistency in other standards. Each entry consists of the case number, the English equivalent of the Chinese term, and the definition. In the entries of this standard, the priority terms are always in bold. The priority terms that appear in the definition or note and are defined in other items of the standard are also in bold, and are followed by the corresponding item number (such as brackets). In the terms in this standard, parentheses "\" are used for annotations or supplementary explanations. 1 Scope
