Principle of Image Recording Principle of Image Recording
An analogy for the recording and playback process would be Carousel slide projector and a Carousel slide An analogy for the recording and playback process would be Carousel slide projector and a Carousel slide
tray. Think of the Processor as a Carousel slide projector and the Random Access Memory (RAM) as tray. Think of the Processor as a Carousel slide projector and the Random Access Memory (RAM) as
the Carousel slide tray. For our discussion the RAM is divided into small sections or frames that are just the Carousel slide tray. For our discussion the RAM is divided into small sections or frames that are just
large enough to hold a single video image. These frames can be thought of as the pockets in a slide tray large enough to hold a single video image. These frames can be thought of as the pockets in a slide tray
that hold the slides or images. In this analogy the slide tray holds 546 slides or the processor memory that hold the slides or images. In this analogy the slide tray holds 546 slides or the processor memory
has 546 frames. has 546 frames.
A slide tray is usually loaded with slides starting at location number one and continuing on around the A slide tray is usually loaded with slides starting at location number one and continuing on around the
tray in sequence until the last location is loaded. When the slide tray is full, a slide must be removed tray in sequence until the last location is loaded. When the slide tray is full, a slide must be removed
before another slide can be put in. The processor memory is loaded with images in a similar way. The before another slide can be put in. The processor memory is loaded with images in a similar way. The
first image is placed in the first frame of processor memory. The second image is placed in the next frame first image is placed in the first frame of processor memory. The second image is placed in the next frame
and so on until last image is placed in the last location. When the memory of the processor is full, the and so on until last image is placed in the last location. When the memory of the processor is full, the
processor erases the first frame and place another frame in place. This process continues for a period of processor erases the first frame and place another frame in place. This process continues for a period of
one round of the whole frames. As a result, the processor memory alwary holds the latest images. one round of the whole frames. As a result, the processor memory alwary holds the latest images.
