The device, which doesn't yet have a name, was one of several shown in Las Vegas ahead of the Consumer Electronics Show.
"It'll come out in the spring of 2011 and the price, we haven't decided yet," said Chris Casper, a group manager at Toshiba's digital products division. (See video of the new tablet on YouTube.)
The demo device is running Android 2.2, but Toshiba hopes to have Android 3.0 in the launch model. The new version of Google's operating system, codenamed Honeycomb, has better support for tablets than current versions.
The tablet includes Toshiba's Resolution Plus, which enhances standard-definition video to give it the appearance of high-def. Until now the system has run on a custom chip, Toshiba's SpursEngine processor, but in the tablet it makes use of the Nvidia Tegra processor.
The computer will have a 10in screen with 1280x800 pixel resolution, and two webcams. The front-facing camera is 2Mp and the rear-facing camera is 5Mp. It has connectors for USB, Mini USB, HDMI and an SD Card slot.
Toshiba also showed off a new version of its Qosmio multimedia laptop with built-in 3D display. The display doesn't require 3D glasses. It has dual cameras that track the user's eyes and help the laptop deliver a picture with the illusion of depth.
Like no-glasses 3D TVs shown previously by the company in Japan, the technology relies on a custom-developed screen made by Toshiba, but it isn't perfect. While the center of the image was clear and appeared to have depth, the edges of the image were blurred.
