Signal Processing in a Digital Camera
Simply converting an analog image that is captured by the CCD into digital data does not create a digital image. Only after the image processing engine performs a variety of calculations on a huge amount of digital image data can we see a completed color image. Since this processing is directly related to color accuracy, image detail and shooting performance, it ultimately determines the digital camera's performance level.

Elements Affecting Digital Image Quality
A digital camera's image quality is determined by three elements: lens performance, CCD image sensor pixel count and performance, and image processing engine performance.
 
 
Digital Camera Shooting Speed
As shown above, since a series of processing steps must be completed on a massive amount of image data, the speed of a digital camera is determined by its image processing engine and compression performance. High-performance digital cameras let you catch more photo opportunities because they have less time lag (the time from when the shutter is pressed to when the image is actually recorded) and a shorter shooting interval.
