The PowerShot A640 and A630 digital cameras are equipped with high resolution 10.0 and 8.0 Megapixel CCDs respectively. Both cameras feature the same body design, high-quality Canon 4x Optical Zoom lens, optical viewfinder as well as a 2.5-inch Vari-Angle LCD screen.

Both cameras are equipped with a 9-point AiAF ďSmartĒ autofocus system and 21 shooting modes. The standard Shooting Modes are Full Auto, Program, Shutter-priority, Aperture-priority, Manual, and Custom with additional modes including Portrait, Landscape, Night Scene, Special Scene (10 varieties), Stitch Assist and Movie. Both models are capable of recording 30 fps VGA movies with sound for up to 36 minutes when using an optional 4GB SD memory card.
Two new shooting features for the A-Series line are Safety Zoom and Digital Tele-converter. The Safety zoom function allows users to comfortably explore digital zoom without sacrificing image quality while the new Digital Tele-converter digitally emulates having a traditional tele- converter attached.
Canonís enhanced (from previous models) "My Colors" mode provides PowerShot users with an incredible range of creative photo effects, which can be accessed directly from the camera with no need for post-processing in a computer. Consumers can adjust a specific color within an image to modify the look and feel of their picture. Available My Color playback modes include Vivid Blue, Vivid Green, Vivid Red, lighter and darker skin tones, as well as options for creating black & white, sepia, neutral and positive film effects. Where previously, users could only enable "My Colors" while shooting, the updated My Colors mode lets users retouch captured images as well, without the need for special software applications or tools.
Because of Canonís proprietary DIGIC II (Digital Imaging Integrated Circuit) image processor, consumers can enjoy long battery life, smooth operation, accurate color reproduction, and excellent image quality. The DIGIC II chip combines the roles of image processing and camera function control into one chip, resulting in faster display and write times for each image and lower power consumption, which extends battery life.
Whether it is raising your camera above your head to get a shot of your child at her first dance recital or dropping your camera below your knees to watch your baby crawl for the first time, the large 2.5-inch vari-angle color LCD screen increases the ability to get those hard to view, but essential shots. The A640 and A630 digital cameras use four AA batteries, while providing more shots (up to 500 with LCD screen on, based on CIPA standards when using rechargeable NiMH batteries) than previous models, thanks to reductions in power consumption made possible by improvements in key components and circuit design.
Optional accessories include NiMH Rechargeable Battery & Charger Kit CBK4-300, AC Adapter Kit ACK900, Underwater Housing WP-DC8, High Power Flash HF-DC1, Conversion Lens Adapter LA-DC58F and the choice of wide-angle, telephoto and macro supplementary lenses. (These are the same supplementary lenses used by Canonís high-end PowerShot G6 digital camera.)
The Canon PowerShot A640 and A630 Digital cameras will be available in October for estimated selling prices of $399.99 and $299.99.
