National foreword

This British Standard reproduces verbatim ISO 2382-13:1984 and implements it as the UK national standard.

This British Standard is published under the direction of the Information Technology Systems Standards Policy Committee which has the responsibility to:

aid enquirers to understand the text;
present to the responsible international committee any enquiries on interpretation, or proposals for change, and keep UK interests informed;
monitor related international and European developments and promulgate them in the UK.
NOTE International and European Standards, as well as overseas standards, are available from BSI Sales Department, BSI, Linford Wood, Milton Keynes, MK14 6LE.

A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.

Compliance with a British Standard does not of itself confer immunity from legal obligations.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting.

International Standard ISO 2382/13 was prepared by Technical Committee ISO/TC 97, Information processing systems.

0 Introduction

Data processing gives rise to numerous international exchanges of both intellectual and material nature. These exchanges often become difficult, either because of the great variety of terms used in various fields or languages to express the same concept, or because of the absence or imprecision of the definitions of useful concepts.

To avoid misunderstandings and to facilitate such exchanges, it is essential to clarify the concepts, to select terms to be used in various languages or in various countries to express the same concept and to establish definitions providing satisfactory equivalents for the various terms in different languages.

This International Standard was initially based mainly on the usage to be found in the Vocabulary of Information Processing, established and published by the International Federation for Information Processing and the International Computation Centre, and in the USA Standard Vocabulary for Information Processing and its revised edition, established and published by the American National Standards Institute (formerly known as the American Standards Association). Published and draft International Standards relating to data processing and documentation from other international organizations (such as the International Telecommunication Union and the International Electrotechnical Commission) together with published and draft national standards have been considered.

The purpose of this International Standard is to provide definitions that are rigorous, uncomplicated and which can be understood by all concerned. The scope of each concept defined has been chosen to provide a definition that is suitable for general application. In those circumstances, where a restricted application is concerned, the definition may need to be more specific.

However, while it is possible to maintain the self-consistency of individual parts, the reader is warned that the dynamics of language and the problems associated with the standardization and maintenance of vocabularies may introduce duplications and inconsistencies between parts.

Section one: General

1 Scope and field of application

This International Standard is intended to facilitate international communication in data processing. It presents, in two languages, terms and definitions of selected concepts relevant to the field of data processing and identifies relationships between the entries.

In order to facilitate their translation into other languages, the definitions are drafted so as to avoid, as far as possible, any peculiarity attached to a language.

This part of ISO 2382 which will comprise some twenty parts deals with the most currently used concepts on computer graphics.

This part of ISO 2382 also deals with the representation and storage of images, the addressing techniques and concepts, the functional units, the processes and methods of operations.
