How Sony Is Fueling the Computer Vision Boom

He didn’t know it at the time, but in 1990 Eric Fossum started a revolution. In the early ‘90s, NASA was firing rockets into orbit every other month. And to take images of outer space, each spacecraft was equipped with cameras.

The problem was, these cameras were absolutely huge—roughly as big as a double-door fridge. Cameras used on spacecraft are similar to digital cameras, except they have to be a lot tougher. And they required tons of heavy wiring to work.

So NASA hired hotshot engineer Eric Fossum straight from Yale, and tasked him with miniaturizing NASA’s cameras. Within two years, Fossum created a “camera-on-a-chip”—a new type of image sensor that was smaller and consumed 100X less power.

Image sensors are tiny computer chips that essentially give cameras a set of “eyes.” They process light from the outside world and transform it into a bunch of 1s and 0s, allowing cameras to render images. Fossum’s “camera-on-a-chip” helped NASA slash the size of its cameras. But more important, his invention laid the groundwork for digital cameras and camera phones.

Today, There’s an Image Sensor Behind Every Camera Lens

You can see the sensor inside a smartphone here:

The rise of smartphones has been a boon for the sensor industry. Before camera phones, sensors were mostly used in digital cameras. And even during their best year ever, camera sales peaked at 121 million units in 2010.

But last year 1.4 billion smartphones shipped around the world. Today over five billion people across the globe own a smartphone… and most of them have at least one image sensor inside. In 2010, total image sensor sales were under $2 billion/year. Sensor sales to smartphone makers alone will hit $8 billion this year.

And the market for image sensors is set to explode again. These days sensors aren’t only inside cameras, but cars, security cameras, medical devices, drones, grocery stores, and factories. In fact, image sensors are in practically everything today, as you can see:

Image sensor sales are expected to hit $29 billion/year by 2024 as they ride this new wave of growth.

Cameras with Brains

Remember, image sensors give cameras a set of “eyes.” These tiny chips allow machines to convert what they see in the real world into digital photographs. But having a set of eyes isn’t the same as being able to “see.”

Until recently, computers have never been able to master vision. Even in 2012, the world’s best image-recognition computer was still laughably bad at recognizing images. But Alex Krizhevsky’s “big breakthrough” changed everything. AlexNet marked the first time in history a machine could identify objects better than a human.
