well im doing the best i can since im writing this from my own knowledge, so bear with me here. first a lens(es) focuses the light onto a ccd to form an image, preferably crisp and clear. the ccd (charge coupled device) translates the light information into electonic data. however, ccds are made up of "cells" with each cell being sensitive to one color(red, green, or blue). since all light is made up of varying amounts of r,g, and b, an image of a purple dinosaur would cause all the red and blue- sensitive "cells" to send a signal , and a white piece of paper would cause all the "cells" to send a signal to the processor (rgb=white). depending on what colors are in the image, different sequences of colors are sent to a processor for processing (and quite frankly, i dont know a lot about this part). anyways, in a analog (vhs tape, etc.) format the signals get recorded onto tape by magnetic bits. (and there are also digital formats that use tape such as minidv, but im not great at explaining the differences.) the analog format might record red as, say, 2 magnetic bits, while digital records them in, say, sequences of magnetic and nonmagnetic spaces for 1 and 0. now what i just said was an example and doesnt mean it actually works that way. anyways back to the point, it gets recorded onto the tape (or digital media, and i really dont know anything about that) and then thats it, until you play it back and see all the cool moving pictures. and thats not including the process of recording sound, which im not gonna go into here.
