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.

    $\begingroup$ 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. $\endgroup$ Aug 20 '16 at 19:25
  • $\begingroup$ 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. $\endgroup$

  • $\begingroup$ 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?" $\endgroup$

    $\begingroup$ 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 ? $\endgroup$
