Digital camera connectivity solutions using the picture transfer protocol (PTP)

Abstract

Interconnectivity of digital camera with other devices is one of the main concerns of consumers and digital camera manufacturers. Interconnectivity features in digital cameras allow more consumer-friendly usage of digital cameras. Moreover, with a suitable application layer software, digital photographs can be sent directly from the camera to a desired target: disk storage, printer, web site, as an e-mail message or web print, using a single, purpose-designed, communication protocol: the Picture Transfer Protocol, PTP.

PTP/IP - a new transport specification for wireless photography

“…For example, discussion of the broader applicability of PTP was presented at ICCE 2002 [4]. This paper introduced some preliminary ideas for implementing PTP over Bluetooth and TCP/IP networks.…”

Real-time network-storage for digital cameras

“…Early work [6], [7] used a dial-up connection but this was soon superseded by Bluetooth [2] and cell-phone network [1] connectivity and then by wireless 802.11b [4]. Later, after the introduction of USB technology in digital cameras, the PTP [3] standard was created to take the full advantage of the increased transfer speeds implementing easy management of capturing and transfer operations.…”

An Open System Design of High Speed Image Transmission

“…With PTP [3][4], digital cameras can exchange images with host computers, printers, other digital capture， imaging and display devices. PTP is a recent standards effort (PIMA15740) from the Photographic & Imaging Manufacturer's Association for connectivity of digital still photography devices.…”
