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. Each 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.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso .org/
iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 42, Photography.
This first edition of ISO 12231-1 cancels and replaces the third edition (ISO 12231:2012), which has
been technically revised. The main changes compared to the previous edition are as follows:
— ISO 12231 was renamed ISO 12231-1;
— the formatting has been switched from a comprehensive vocabulary standard to a supplemental
vocabulary standard, supplementing the ISO Online Browsing Platform;
— unlike previous editions of this document, this edition no longer includes terms and definitions
that were defined by other ISO/TC 42 deliverables (Standards, Technical Specifications or Technical
Reports).
Therefore, from this edition, this document consists of:
a) originally-defined terms and definitions, and
b) useful terms and definitions for electronic still picture imaging that are referred from other
standard bodies outside of ISO/TC 42.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/ members .html.

Introduction
Electronic still picture imaging concepts are drawn from traditional photography, electronics, video,
and information technology. In some cases, the concepts are redefined to apply to electronic still
picture imaging. For example, unlike traditional photography, measurements cannot be defined in
terms of “film” or “sensitised material”, since images acquired by digital image capture devices are
stored electronically and are not immediately exposed on film. The meaning of shutter and exposure
time is also different for digital image capture devices, because an electronic imaging sensor typically
has image acquisition characteristics that are different from those of film.
This document provides a vocabulary which standardizes the use and meaning of terms associated with
electronic still picture imaging that were not defined by other ISO/TC 42 deliverables (see Annex A for
a list of related WGs and documents). It is organized alphabetically and follows natural (English) word
order wherever possible.
