Electronics giant Sony Corp. said Wednesday it will begin sales this month of the compact "Cyber-shot T" series that can detect a smile and immediately drop the shutter.
The photographer can program the camera to detect which type of facial expression to look for, be it a faint smile or a tooth-baring grin, a Sony spokeswoman said.
But the camera is not exclusively designed to take pictures of happy moments, she added. The user can turn off the function and use it as a normal camera.
