'High-definition' iPad rumored

• Tweet

CUPERTINO, Calif., July 8 (UPI) -- Apple's rumored next iPad could have a higher-resolution screen capable of being used for high-end video editing and photography, analysts say.

A blog called This Is My Next has dubbed it "iPad HD" and cites unnamed sources saying it will be released in September with a screen having twice the resolution of the current model, CNN reported Friday.

Another tech Web site says the rumor is credible since Apple has been releasing high-resolution versions of tablet content.

"Apple started including pixel-doubled artwork in versions of iBooks for iPad some time ago," Ars Technica said. "It recently added yet more 2,048-by-1,536 pixel artwork in iOS 5 betas for newer features like Twitter and Newsstand.

"So it seems a pretty safe bet that a future iPad will definitely use this resolution," the site said.

Analysts question whether Apple would start a second, high-end line of tablet computers.

"The screen itself would be so expensive that it'd be impossible to hit the $500 starting point pegged to the consumer versions of the iPad," the blog Techland said.

Apple's second-generation iPad went on sale in March against a host of competing tablets, mostly running Google's Android operating system, but none has sold as well as the iPad.
