...Nikon isn't the only big brand whose consumer cameras have displayed an occasional - though clearly unintentional - bias toward Caucasian faces. Face detection, one of the latest "intelligent" technologies to trickle down to consumer cameras, is supposed to make photography more convenient. Some cameras with face detection are designed to warn you when someone blinks; others are programmed to automatically take a picture when somebody smiles - a feature that, theoretically, makes the whole problem of timing your shot to catch the brief glimpse of a grin obsolete. Face detection has also found its way into computer webcams, where...
...principle behind face detection is relatively simple, even if the math involved can be complex. Most people have two eyes, eyebrows, a nose and lips - and an algorithm can be trained to look for those common features, or more specifically, their shadows. (For instance, when you take a normal image and heighten the contrast, eye sockets can look like two dark circles.) But even if face detection seems pretty straightforward, the execution isn't always smooth. (See the 50 best inventions...
...Indeed, just last month, a white employee at an RV dealership in Texas posted a YouTube video showing a black co-worker trying to get the built-in webcam on an HP Pavilion laptop to detect his face and track his movements. The camera zoomed in on the white employee and panned to follow her, but whenever the black employee came into the frame, the webcam stopped dead in its tracks. "I think my blackness is interfering with the computer's ability to follow me," the black employee jokingly concludes in the video. "Hewlett-Packard computers are racist." (See pictures...
...Still, some engineers question how a webcam even made it onto the market with this seemingly glaring flaw. "It's surprising HP didn't get this right," says Bill Anderson, president of Oculis Labs in Hunt Valley, Md., a company that develops security software that uses face recognition to protect work computers from prying eyes. "These things are solvable." Case in point: Sensible Vision, which develops the face-recognition security software that comes with some Dell computers, said their software had no trouble picking up the black employee's face when they tested the YouTube video...
...will also supply the software to well-known brands, which might explain why HP isn't the only company whose cameras have exhibited an accidental prejudice against minorities, since many brands could be using the same flawed code. TIME tested two of Sony's latest Cyber-shot models with face detection (the DSC-TX1 and DSC-WX1) and found they, too, had a tendency to ignore camera subjects with dark complexions...
