Picture Transfer Protocol
Picture Transfer Protocol (PTP) is a protocol originally developed by the Photographic and Imaging Manufacturers Association (PIMA) (later known as the International Imaging Industry Association) to allow the transfer of images from digital cameras to computers and other peripheral devices without the need for additional device drivers. The protocol was standardized by the ISO in 2005. The current version of the standard is ISO 15740:2013.

It is further standardized for USB by the USB Implementers Forum as the still image capture device class. USB is the default network transport media for PTP devices. USB PTP is a common alternative to the USB mass-storage device class (USB MSC), as a digital camera connection protocol. Some cameras support both modes.
