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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 20087 was prepared by Technical Committee ISO/TC 42, Photography.

Introduction
For digital cameras, long battery life is one of the important features. The Camera & Imaging Products
Association (CIPA) defined a CIPA standard “Procedure for Measuring Digital Still Camera Battery
Consumption” for specifying a standard measurement procedure. The procedure gives useful information on
battery life to end-users for making a selection from a variety of digital cameras.
This international standard is based on the CIPA standard mentioned above and it is referenced in
Bibliography. The standardized measurement procedure primarily includes high power-consuming functions
such as image display on picture monitor, use of flash, and zoom and retractable lens movement.

DRAFT INTERNATIONAL STANDARD ISO/DIS 20087

Photography — Digital cameras — Battery life measurement
1 Scope
This Standard applies to consumer-use digital still cameras (hereinafter referred to as “DSC”).
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
number of shots
number of pictures shot by a digital camera under the conditions stipulated in the measurement procedure in
this standard.
3 Measurement method
3.1 General
a) All the still-photography functions shall be utilized to their full extent when the measurement is conducted.
The functions which have nothing to do with taking still photography (e.g. audio- and movie-recording
functions) need not be activated during the measurement.
b) The camera’s function-setting parameters, except those defined in this international standard, shall be
identical to factory shipping settings. If the measurement is conducted with the parameters different from
the factory shipping settings, such settings parameters shall be reported along with the measurement
results. If certain setting parameter are not defined by the factory shipping settings (see Annex B), the
measurement shall be conducted using the settings which are most likely employed by the users of the
applicable cameras, and information which can identify such setting parameters shall be reported along
with the measurement data.
c) Some of the functions whose test conditions are defined in this standard may be ignored if a camera to be
measured is not equipped with those functions.
Summarized priorities for the above a), b) and c) are as follows:
1) The measurement conditions of the standard procedure which are listed in 3.2-3.8.
2) Function-setting parameters which are not listed in 3.2-3.8 shall be identical to the factory shipping
settings.
3) If any parameters which cannot be defined by the factory shipping settings, such parameters shall be
set to ones which are assumed to be employed most likely by the users of the applicable cameras.
d) If the power level is not fully determined by the factory shipping setting, the measurement shall be made
to have the highest power demand.

3.2 Battery
a) Battery type is not specified for the measurement, but information that can identify the battery shall be
reported along with the measurement results.
b) When using a primary battery, a new battery shall be used. When using a secondary battery
(rechargeable battery), the battery shall be fully charged (see Annex B).
3.3 Recording media
Not specified, but information that can identify the recording media shall be reported along with the
measurement results.
3.4 Camera settings
3.4.1 Image quality mode
The factory shipping mode shall be used.
3.4.2 Number of recorded pixels
The factory shipping mode shall be used.
3.5 Measurement conditions
3.5.1 Subject distance
Not specified.
3.5.2 Subject to be shot and brightness
Subject to be shot is not specified. The subject brightness shall be within the range of the camera's AE system,
if automatic exposure (AE) is used.
3.5.3 Operating environment
Measurements shall be made at (23 ± 2) ºC and relative humidity (50 ± 20)%.
3.6 Required actions
3.6.1 Flash usage
Full flash shall be used for one of every two shots. For the other shot, the flash shall not be used. (Any given
shooting condition for the full illumination flash may be used.)
3.6.2 Motor driven optical zoom operation
The motor driven optical zoom lens shall be moved either from the TELE end to the
...
