Sanyo has unveiled what they claim is the smallest and lightest HD digital cam on the planet. With a volume of only 16.6 cubic inches and a weight of only 9.5 ounces, the Xacti HD 1000 features an 1920 x 1080 pixel resolution that can record up to 85 minutes of 1081i high-def or over 5 hours of TV quality video with an 8G SD card (not included.)  Sanyo’s new technology allows for only one processing chip while utilizing 4.2 watts of power. Its “Face Chaser” automatically detects and isolates up to 12 figures for auto-focus and proper exposure. The Xacti will be available in the U.S. next month and will retail for $799.99, which makes it about $84.00 per ounce.
