Sony, HP, others propose new specs for digital imaging

A group of six digital still camera makers and printer vendors, including Sony and Hewlett-Packard (HP), have jointly proposed a new industry standard that allows images recorded by a digital still camera to be printed out without using a computer, they announced on Monday.

The DPS standard -- which is a name, not an acronym -- is being proposed by Canon, Sony, HP, Fuji Photo Film, Olympus Optical and Seiko Epson.

Previously, each manufacturer used a proprietary method for printing pictures directly from their digital still camera, making it difficult for users to mix equipment from different vendors.

The first version of the standard is expected to be released by February next year, said Nobuaki Sakurada, a Canon representative, at a news conference in Tokyo on Monday.

The DPS specifications are expected to be adopted on mobile handsets' digital cameras in the near future, and ultimately storage vendors will be able to develop DPS-compliant products, they said.

DPS, originally developed by Canon, HP, Seiko Epson and Sony, is written for USB (universal serial bus) connections with PTP (Picture Transfer Protocol) as data transfer protocol, they said.

The standard has been designed for scalability and simplicity, using the same interface for all cameras. After a USB cable is connected between a camera and a printer, the user chooses an image on the cameras' LCD (liquid crystal display) monitor. By simply pressing a button on the camera, a printer responds and prints out the image. Advanced functions contained in higher-end cameras can be operated by an extended user interface, Sakurada said.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
