AnandTech has published the second part of their guide about digital camera sensors:
Part 1 then covered the technology of current sensors with a closer look at Bayer (and related Fuji Super CCD) and Foveon sensors. Finally, the current move to CMOS sensors from CCD sensors was explored by looking at the advantages and disadvantages of each sensor type and the role of the supporting analog-to-digital chips required in each design.
With this knowledge of digital camera sensors and how they capture images, Part 2 will take a brief look at how captured pixels are then converted to a usable image. This will examine how in-camera processing works to produce JPEG files. The advantages and disadvantages of the alternative RAW image capture with post processing is also explored.
