<p>I really cannot get my head around on this issue - how does an analogue image is sampled and then stored in a ture-colour frame buffer (e.g. in a camera) and how do you prevent noise when you do so? Read multiple articles on it but I cannot really get it. </p>

Can you be more specific about what you do and don't get? Right now we're just guessing about what kind of explanation would help you.

Well, it is an old computer graphics exam question, perhaps I should have started with this and I decided to work on it a bit to prepare myself for future examinations.

The question goes as stated "How does an analogue image is sampled and then stored in a ture-colour frame buffer (e.g. in a camera) and how do you prevent noise when you do so?"

The question is a bit ambiguous, are we talking about the A-to-D process that goes on in the sensor? Or are we talking about the bayer conversion camera sensor arrays need to apply to convert sensor data into RGB ?

How do you sample an analogue image and store it in a true-colour frame buffer?
