Sony announced today its S-Frame brand of digital photo frames: the DPF-V900, DPF-V700, and DPF-D70. All models have WVGA resolution (800-by-480 pixels), 15:9 aspect-ratio screens, and an advanced image processor that "scales and displays images up to 48 megapixels, making the frames capable of handling photos taken with the most advanced digital cameras."

The models also feature 10 slide show variations, clock and calendar views, and two index modes so you can preview several photos at once—all standard options I've seen with many digital photo frames on the market. The 7-inch DPF-V700 and 9-inch DPF-V900 digital photo frames have 512MB of internal storage, while the 7-inch DPF-D70 model has 256MB of internal flash memory.

What sets the DPF-V900 and DPF-V700 frames from other models is that they offer Bluetooth functionality and HDTV connectivity via an HDMI cable. Using a Bluetooth adaptor, sold separately, the frames can import images wirelessly from a Bluetooth-enabled device. Both frames also connect to Sony BRAVIA and other compatible HDTV sets to display your photos in high definition. These two models also feature Sony's Bionz processor with face detection technology for faster processing speeds and in-frame photo corrections.

The DPF-V900, DPF-V700, and DPF-D70 digital photo frames will be available for $250, $190, and $140, respectively in March.
