THE DIGITAL SIGNAL PATH
Let’s take a look at how the image is acquired and recorded in modern digital cameras; just a quick overview and then we’ll get into the details later. The lens projects the scene image onto the sensor which reacts to light by producing voltage fluctuations proportional to the levels in the scene.

The data from the ADC then goes to the ...
