Saw an advert for Sanyo 'dual' cameras recently. Their website says this:
Xacti Dual Cameras expand your shooting range by
combining the video abilities of a camcorder with the photo-capture abilities of a digital camera. In your choice of a horizontal or vertical design, a Dual Camera offers comfortable one-handed shooting and the ability to switch modes with a single thumb-press of the Photo or Video button. At the top of the range,
full HD models record high-definition 1080p videos that look spectacular played back on a connected wide-screen display. All Dual Camera models feature powerful zoom and sequential shooting functions, while some models are fully waterproofed for extended underwater recording. Xacti Dual Cameras by SANYO—one is all you need.
