LONDON--A new type of image sensor that's been flipped front to back is beginning to give photographers a better view of the world.

The new sensors use a technology called backside illumination, and chipmakers including Sony and Samsung are leading the charge to build them into a variety of cameras. And though it's a premium feature today, it's spreading rapidly across the market.
"It's more aggressive than we expected even two years ago," Yole Developpement analyst Jerome Baron said in a talk last week at the Image Sensors Europe conference here.
Image sensors are special-purpose, light-sensitive chips packed with complicated technology. But backside illumination, or BSI, is pretty easy to understand: flip the sensor around so the light it's detecting isn't partially blocked by a bunch of electronics. What used to be the back of the sensor is now facing outward toward the light.
Better sensitivity
The advantage, illustrated among other places in the iPhone 4 camera, is better light sensitivity. That opens up new options for camera makers.​

Waiting for iPhone 5! Hopefuly it won't be more expensive than the iPhone 4.​

When I saw the topic, I thought that someone had been shining a torch on your backside.

I thought to myself, they're a strange mob north of the Yarra.
