A leak today has revealed that Hitachi is planning the imminent launch of only the second phone to record HD video after Samsung's Omnia HD. Named in the brochure as the Hi-Vision Cam Wooo, the thin swivel phone found by Engadget would have a 5-megapixel camera capable of recording 720p video along with face detection. It would also get HDMI video output and a microSDHC slot that, with an 8GB card, could hold 2 hours of footage.

Few other details are visible from the documents, but the phone is known to have a 3-inch, wide VGA (roughly 480x800) LCD using in-plane switching for better color accuracy. More details are expected soon as the phone is likely to be launched on Monday as part of Japanese carrier KDDI's summer lineup. A North American release is unlikely.
