Leaders in Digital Imaging Market Propose New Industry Standard for Direct Printing from Digital Still Cameras
PALO ALTO, Calif., and TOKYO, Dec. 2, 2002 -- Canon Inc., Fuji Photo Film Co., Ltd., HP, Olympus Optical Co., Ltd., Seiko Epson Corporation and Sony Corporation today announced a proposal for an industry standard that enables consumers to easily print photos by directly connecting their digital still cameras to their printers -- no PC required.
Until now, each company had its own proprietary solution for direct printing -- without a computer -- between their own branded digital still cameras and printers. This situation has proven to be limiting to consumers, as they are unable to achieve the same convenience and ease of use when using a combination of products of different brands. The unified specification, tentatively named "DPS," ensures compatibility across digital cameras and printers, regardless of brand, giving consumers the flexibility and simplicity to create high-quality photos.
The specification was originally developed by Canon, HP, Seiko Epson and Sony. Fuji and Olympus later joined discussions and collectively the specification was finalized. Together, these six companies, all leaders in digital imaging, will continue to advocate industry adoption of this new standard, which is expected to spur the growth of digital photography.
DPS specifies an application layer control protocol and is independent from any physical transport. It was designed to be extensible for implementation on future physical interfaces. The DPS version 1.0 document, which will be published formally later, is written for USB as a physical transport and Picture Transfer Protocol(1) as data transfer protocol. Consumers can simply connect a DPS-enabled digital still camera to a DPS-enabled printer, using the camera to perform operations and easily print high-quality photos.
The following features are supported by a DPS system according to the recommended specifications:
The following printer status information is displayed on digital still camera:
More information on DPS is available at http://www.camera-direct.info/.
(1) Picture Transfer Protocol (PTP) was developed by the International Imaging Industry Association, an industry standard body, as a standard for image file transfer. With this protocol, image files can be transferred between a digital still camera and PC via USB.
(2) Digital Print Order Format (DPOF) is a standard format control file that is stored in the digital still camera's removable memory card, which specifies which image files should be printed, and the number of copies.
