Visual aesthetics and the image signal processor
There are times when a beautiful image is exactly what your eye sees, but more often a beautiful image is what your mind’s eye sees. To put it bluntly, life–real life–has warts, blotches, and stains. The sky really isn’t the color blue you remember, and the camera can add 10 pounds.
But fear not, we have a solution. We employ advanced, precedent-setting algorithms to manage everything from color saturation and white balance to noise reduction and dark current. We stabilize images and blast the blurry. We help ensure beautiful pictures in virtually any scenario, and we do it with flexible image signal processors and all-in-one system-on-chip (SOC) solutions.

SOCs and ISPs improve the picture you see
Digital image signal processors (ISPs) and SOCs use algorithms, or well-defined step-by-step instructions, to adjust the raw data an image sensor collects so that the processed image or video is more visually pleasing than the original. Put another way, SOCs and ISPs make the image look more like what the mind’s eye sees, eliminating image blemishes, compensating for poor lighting conditions, or even correcting for a shaky hand or for bad focus.
The process is the kind of magic that can’t be left to an acolyte or imaging neophyte. Good image correction is the result of years of experience and innovation. It requires a precise understanding of how light energy is converted into digital signals, and it requires an intuitive aesthetic. We’ve been doing and experimenting with image processing for more than a decade. We have the experience and the artfulness to process great images and video. And our experience helped us offer one of the industry’s first SOCs and lead the way with companion chip digital image signal processors.
This image-improving magic can take place either in an SOC or in an ISP.
SOCs — powerful processing on a single chip
SOCs, which are built right on to the image sensor at the silicon level, have several key advantages. They’re designed to work perfectly with the sensor they are attached to, so the SOC’s signal processing is at its best when the sensor is the most challenged. They’re a compact, one-chip solution, making them easy to integrate, which can potentially lower overall system cost.
More SOCs and ISPs to come
Digital images and video have sparked a revolution in both consumer electronics and social interaction. Virtually everywhere on Earth people are taking photos with their camera phones, digital still cameras, or web cams and sharing the resulting images on YouTube, Flickr, Facebook, or MySpace. They are emailing images, printing images, and sharing those images every moment of every day.
Analysts expect consumers to purchase more than one billion camera phones each year by 2010. More than half of those mobile handsets will have two cameras each, essentially requiring a companion chip or SOC solution.
