TOKYO — If a picture's worth a thousand words, then how much is a smiling photo worth? About 40,000 yen ($350), based on Sony's new "smile shutter" cameras.
Using face-detection technology, the 8-megapixel, DSC-T70 and DSC-T200 Cyber-shot cameras won't snap a high-definition picture until a selected subject smiles.
Even with more than a handful of people in a picture, a photographer can designate which face to focus on by touching an LCD panel with a special pen.
