Picture Transfer Protocol (PTP)for Digital Still Photography Devices
For the purposes of this standard, digital still photography devices (DSPDs) are defined as
devices with persistent storage that capture a digital two-dimensional image at a discrete point
in time. Most DSPDs include interfaces that can be used to connect to a host computer or other
imaging devices, such as a printer. A number of new, high speed interface transports have
recently been developed, including IrDA, USB, and IEEE1394 (Firewire). This standard is
designed to provide requirements for communicating with DSPDs. This includes
communications with any type of device, including host computers, direct printers and other
DSPDs over a suitable transport. The requirements include standard image referencing
behavior, operations, responses, events, device properties, datasets, and data formats to ensure
interoperability. This standard also provides optional operations and formats, as well as
extension mechanisms.
This standard has been designed to appropriately support popular image formats used in digital
still cameras, including the EXIF and TIFF/EP formats defined in ISO 12234-1 and ISO 12234-
2, as well as the Design Rule for Camera File System (DCF) and the Digital Print Order Format
(DPOF).
