Sony Computer Entertainment Inc (SCE) delivered a lecture on its "PlayView" image processing technology, which can scale an image up and down at a high speed, at CEDEC 2010.

CEDEC 2010 took place from Aug 31 to Sept 2, 2010, in Yokohama City, Japan.

The PlayView is the technology that SCE has been developing as the "high-quality image enlargement technology." And the company is now providing contents using the technology for the PlayStation 3 (PS3) users.

SCE started the development of the PlayView in the aim of viewing images having more than 1 billion pixels with no delay, said Teiji Yutaka, senior vice president, Software Solution Development, SCE, who took the platform.

In the lecture, Yutaka used the "PlayStation Move Motion Controller," a motion-sensitive controller for the PS3, to control the PS3 equipped with the PlayView and demonstrated the technology. For example, he increased and reduced the size of a still image of a park that has a pixel count of about 3.2 billion (34,800 x 92,300).

At first, it looked as though the image only showed a gigantic object. But, when it was enlarged, a human figure began to appear. After further magnification, the figure turned out to be a woman. Also, a flying bird could be seen in the enlarged image.

Yutaka demonstrated this sequence of actions in real time, surprising the audience.

The PlayView can deal with not only still pictures but also movies, music, hypertext links, etc. And SCE plans to use the PlayView for electronic documents such as the instruction manuals and guides for game software and start a service called "PlayView for Games" in the fall of 2010.

For example, a movie can be embedded in a guide for game software to explain how to play the game. SCE intends to utilize the PlayView not only for the instruction manuals and guides for game software but also in games. For example, it is possible to display a large number of game stages on one screen and enable the user to select a stage by zooming in and out the screen.
