17、(E)IntroductionFor digital cameras, long battery life is one of the important features. The Camera and 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 u
18、seful 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 the Bibliography. The standardized measurement procedure primarily includes high power-consuming f
19、unctions such as image display on picture monitor, use of flash, and zoom and retractable lens movement. ISO 2016 All rights reserved vBS ISO 20087:2016BS ISO 20087:2016Photography Digital still cameras Battery life measurement1 ScopeThis International Standard specifies measurement method of batter
20、y life for consumer-use digital still cameras (hereinafter referred to as “DSC”).2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1number of shotsnumber of pictures shot by a digital camera under the conditions stipulated in the measurement proced
21、ure in this International Standard3 Measurement method3.1 Generala) 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-recording and movie-recording functions)
22、need not be activated during the measurement.b) The cameras function-setting parameters, except those defined in this International Standard, shall be identical to factory shipping settings. If the measurement is conducted with parameters that are different from the factory shipping settings, such s
23、ettings parameters shall be reported along with the measurement results. If certain setting parameters 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 info
24、rmation 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 International Standard may be ignored if a camera to be measured is not equipped with those functions.d) If the power level is not f
25、ully determined by the factory shipping setting, the measurement shall be made with the operation that result in the highest power demand level for the camera.Summarized priorities for the above a), b) and c) are as follows. The measurement conditions of the standard procedure which are listed in 3.
26、2 to 3.8. Function-setting parameters which are not listed in 3.2 to 3.8 shall be identical to the factory shipping settings. If any parameters cannot be defined by the factory shipping settings, such parameters shall be set to ones which are assumed to be most likely employed by the users of the ap
27、plicable cameras.3.2 Batterya) Battery type is not specified for the measurement, but information that can identify the battery shall be reported along with the measurement results.INTERNATIONAL STANDARD ISO 20087:2016(E) ISO 2016 All rights reserved 1BS ISO 20087:2016ISO 20087:2016(E)b) When using
28、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 mediaNot specified, but information that can identify the recording media shall be reported along with the measurement results.3.4 Cam
29、era settings3.4.1 Image quality modeThe factory shipping mode shall be used.3.4.2 Number of recorded pixelsThe factory shipping mode shall be used.3.5 Measurement conditions3.5.1 Subject distanceNot specified.3.5.2 Subject to be shot and brightnessSubject to be shot is not specified. The subject bri
30、ghtness shall be within the range of the cameras AE system, if automatic exposure (AE) is used.3.5.3 Operating environmentMeasurements shall be made at (23 2) C and relative humidity (50 20) %.3.6 Required actions3.6.1 Flash usageFull flash shall be used for one of every two shots. For the other sho
31、t, 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 operationThe motor driven optical zoom lens shall be moved either from the TELE end to the WIDE end or from the WIDE end to the TELE end before every picture is ta
32、ken. The zoom lens may be moved either as TELE WIDE TELE or as WIDE TELE WIDE with every two shots. Nothing is specified on its movement during the measurement other than the motor-driven optical zoom operation.3.6.3 Picture monitor modea) The picture monitor shall be turned on at all times to be us
33、ed as the electric viewfinder during the measurement. If the picture monitor turns off automatically during the measurement or if it automatically shifts into other display modes, it shall immediately be turned back into the viewfinder mode either by an automatic or manual operation (except replacin
34、g batteries or power cycling) and the test shall be continued. For cameras equipped with two or more picture monitors, the test can be conducted with only the most power consuming one turned on at all times.2 ISO 2016 All rights reservedBS ISO 20087:2016ISO 20087:2016(E)b) If the picture monitor is
35、equipped with an illumination function (e.g. backlight), the illumination shall be lit for the duration of the test. If the brightness or the contrast of the monitor is adjustable, the adjustable parameter shall be set at the factory shipping setting when the measurement is made.NOTE See Annex B.3.6
36、.4 Handling when the recording medium is fullThe files in the medium shall be deleted immediately with the function in the camera or the medium shall be replaced with an empty one. If replacement is to be done, tester shall minimize the influence on the battery life with the replacement. For example
37、, the tester shall replace the medium when the power is off. It is acceptable to delete files or replace the medium before it becomes full.3.6.5 Handling of playback modeNothing is specified regarding the playback mode including automatic playback (the function for displaying images automatically im
38、mediately after they are shot).3.6.6 Shooting intervalsThe first shot shall be made 30 seconds after the power is turned on. During that 30-second period, the flash mode setting, zoom operation and other preparations setting for shooting shall be made. Thereafter, shooting shall be made at a rate of
39、 one picture every 30 seconds. If 30 seconds is not sufficient for initialization, or if the camera is not ready for shooting in 30 seconds after a shot, shooting shall be made immediately when the camera becomes ready.3.6.7 Power offPower shall be turned off after every tenth picture has been shot
40、and processed. The interval before the next power-on shall be enough time not to affect battery life (i.e. so that any additional off time will not change the measurement results).NOTE See Annex B.3.7 End-of-test criteriaThe measurement shall be finished when the first low-battery shutdown occurs or
41、 when any function related to still photography stops working without low-battery shutdown.However, if the function can be reactivated automatically or manually (except replacing batteries or power cycling), the function shall be reactivated immediately and the test shall be continued.NOTE See Annex
