Picture and video import device requirements in Windows 7

Updated: July 9, 2009

This topic describes the device requirements are necessary for correct operation of picture and video import in Windows 7.

This information applies to the following operating system:

  • Windows 7

Validation of MTP and PTP support in the device

If your device supports Media Transfer Protocol (MTP) or Picture Transfer Protocol (PTP), we recommend that you validate the MTP or PTP implementation in your device by using the tools in the Windows Logo kit (WLK).

For more information about the WLK and Windows Logo Program, see Windows hardware certification.

Devices connected to a computer by using a WPD driver

For devices that connect to a computer by using a Windows Portable Device (WPD) driver, such as the inbox MTP or PTP drivers, implementing the WPD_OBJECT_DATE_CREATED or WPD_OBJECT_DATE_MODIFIED object properties synchronizes the import of picture and video files. By supporting these attributes, only new or modified versions of image files are imported from a device.

For more information about WPD and the WPD object properties, see WPD Object Properties.

To download the PTP and MTP specifications, see ISO 15740:2008 - Picture transfer protocol (PTP) for digital still photography devices and Media Transfer Protocol (MTP) Specification.

Devices that embed orientation metadata in pictures

JPEG and TIFF picture files can include metadata about the orientation of the picture when it was taken. This metadata is specified in the Exchangeable Image File (EXIF) format. By default, JPEG and TIFF picture files that include the EXIF picture orientation property are rotated during import.

For more information about the EXIF format and the picture orientation property, see Exchangeable Image File Format for Digital Still Cameras: EXIF Version 2.2.

Devices that support WMP media synchronization

For devices that support media synchronization and do not support the MTP Hints service, pictures and videos that are taken on a device must be saved to a location different from the default synchronization folders of Windows Media Player (WMP). These folders are named \Pictures and \Video.

This guarantees that new pictures and videos are detected during import. This also improves performance by preventing the import of media synchronized to a device by using WMP.

For more information about multimedia synchronization detection, including the MTP Hints service, see Multimedia synchronization detection for camera-equipped devices by using MTP.
