Image Capture
The basic likeness of, and differences between, a film
and digital camera are described above.
A basic image capture system contains a lens and a detector.
Film detects far more visual information than is possible with
a digital system.With digital photography, the detector is a solid
state image sensor called a charge coupled device...CCD for short.
On an area array CCD, a matrix of hundreds of thousands of microscopic
photocells creates pixels by sensing the light intensity of small
portions of the film image.
Images based on pixel by pixel information, are called raster
images. These are the stored images used in digital cameras.
