Here is the next segment of Angelo and my, Behind the Aperture Series where we discuss the inner workings of digitial cameras and some of the behind the scenes things that need to happen in order to produce a digital image.

Last issue, we talked about image sensors and the role they play in creating digital images. This issue, we’ll be discussing the next block in the imaging system which immediately follows the image sensor and is arguably the most important part of the overall camera system. That very important part called the image signal processor (ISP). An ISP can be thought of as the brains of the imaging system in a camera as it’s in charge of controlling many of the individual parts of a camera that work together in order to produce a usable image.
Within this ISP, there are hundreds of embedded algorithms and features, but the main three that have the largest effect on image quality are known as the three A’s: auto focus (AF), auto exposure (AE), and auto white balance (AWB). More Photos
