Digital cameras — Measurement method for image stabilization performance — Part 1: Optical systems
This document defines the measurement method of optical image stabilization performance for still images compensating for handheld blur consisting of two rotational components, yaw and pitch. It applies to consumer digital cameras with optical image stabilization for still images. Apparatuses such as camcorders and mobile phones with still image shooting functionality are within the scope of this document.

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

Introduction
The image stabilization function is important for digital cameras and has become a selling point in
marketing materials. Therefore, the measurement methods and its reporting method are then very
important to compare the image stabilization performance among cameras based on their brochures.
The Camera & Imaging Products Association (CIPA) issued CIPA standard DC-011 in 2012 to specify
how to measure and describe the optical image stabilization performance of digital cameras. When
image stabilization performance is measured and described according to this standard, end users have
unbiased and useful information to help them select from a variety of digital cameras (see Bibliography).
This document is based on the CIPA standard, which is referenced in the Bibliography. The standardized
measurement method primarily includes performance assessment with simulated handheld camera
movements.
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed
that compliance with this document may involve the use of a patent.
ISO takes no position concerning the evidence, validity, and scope of any of the patent rights. The holders
of the patent rights have assured ISO that they are willing to negotiate licenses under reasonable and
non-discriminatory terms and conditions throughout the world. In this respect, the statement of the
holders of these patent rights is registered with ISO. Information may be obtained from:
