DiG!C 4
The Processor is the Soul of Canon Digital Cameras

A camera�s processor does a lot, quickly��very quickly.

When light strikes each pixel on the sensor, an electronic signal is generated, converted into a digital signal, and sent to the processor. (The more light that strikes a pixel, the stronger the signal it creates.) With each click of the shutter, millions of these signals are produced � one for each pixel on the imaging sensor � and the processor has to use them to create a finished, recognizable image.

Information about color, contrast, image detail, noise and dozens of other computations have to be evaluated and analyzed, and it�s the processor that performs these tasks. At high camera speeds, the number of transactions that the processor manages can reach 500 million per second!

It is a minor miracle that processors do all these things and get it right, time after time. And as image sensors getter larger and more powerful, the number of transactions and instructions the processor must manage grows exponentially.

The more of these mathematical calculations that can be performed, the better the image quality is likely to be. The faster information can be processed, the more functionality can be allowed, and the happier the customer will be not waiting for the camera to warm up or cycle between shots.

With the New DiG!C 4, there�s no waiting involved. Processing in 14 bit depth and 6 frames per second in a digital SLR like the EOS 50D is NOT a problem.
