Going Mobile: Evaluating Smartphone Capture for Collections

There are now institutional guidelines that define several image quality measures, and set performance requirements for image capture. Based on these, it is now common practice to monitor image acquisition performance for digital collections. Important image characteristics include the influence of lighting, lens focus, and several aspects of general imaging practice. Normally these efforts are applied to digital scanners and professional cameras. As cameras in mobile-telephone cameras have improved, however, these are sometimes used as convenient document scanners. Addressing the evaluation of image resolution and optical distortion, we describe how imaging performance can be evaluated against US federal (FADGI) and Matamorfoze guidelines. Results from our smartphone test indicate that, for the attributes tested, the unit would meet at least three-star performance for up to A4 document scanning, and possibly better. We show that it is possible to identify the domain of acquisition conditions under which these cameras can meet the requirements for cultural heritage imaging.

More about this publication?
  • The IS&T (digital) Archiving Conference offers a unique opportunity for imaging scientists and those working in the cultural heritage community (curators, archivists, librarians, photographers etc) from around the world to come together to discuss the most pressing issues related to the digital preservation and stewardship of hardcopy, and other cultural heritage documents and objects. Authors come from museums, archives, libraries, government institutions, industry and academia. Cutting edge topics related to multispectral and 3D imaging, as well as best practices for workflow, sharing, standards, and asset/collection management and dissemination are explored in papers presented at this annual, international event.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in pertuity. Copyright restrictions on papers vary; see individual paper for details.
