Many companies want to utilize the equipment they currently own. The camera is a critically important system component. The best medium for images is still 35 mm film, but electronic imaging is not far behind and the gap is closing rapidly. Film is still better, but how much better is relative. The video and digital cameras on the market today produce outstanding images, thus eliminating the film issue.
Many people confuse video and digital cameras.
Actually, it is difficult to differentiate between a high-quality video image and the image from a digital camera. However, as a rule, a digital camera produces a better image than its video counterpart. A digital camera captures an image, displays that image, and then repeats the capture and display process again and again. Early versions of digital cameras had relatively slow rates of refresh. New cameras use the video signal to find and focus on the area of interest, and then capture in digital mode.
