    Amount of light needed to capture images

    I'm working with a moving video camera and as you might know if there is not enough light lots of frames will be blurry due to slow shutter speed and the need to get as much light as possible. It seems that the best way of proceeding is lots of testing and experimenting with different...

    Amount of light needed to capture images

    Thanks for the reply, definitely a trial and error will be needed. But some theory is good to spec out a prototype Does anybody know where to find information about light formation, to be able to at least estimate the amount of light needed? Thx

    Amount of light needed to capture images

    Hi all, I'm working in application where a camera needs to see in a dark closed area. Imagine a small box, say 8"x8" and there is a camera trying to record inside. In order to get images, we need some light. The problem is how to determine how much light is needed without being too little...

    Prove (A∩B)C=AC∩BC is FALSE: Counterargument Needed

    you don't really need to prove anything.. you just have to come up with a counterexample If you draw a Venn diagram of the 3 sets you can construct your counter example Good luck!

    Accumulation Points: Set with Two or Countably Infinite?

    Homework Statement is there are a set with countably infinite number of accumulation points? Homework Equations is there a set with exactly two distinct accumulation points? The Attempt at a Solution a set with two accumulation points might be: {1/n + (-1)^n} i have no clue about...

    Is the converse of the absolute value limit theorem true?

    Hi all, I'm wondering about this question I can prove that if lim_{n->inf} (a) = L then lim_{n->inf}abs(a) = abs(L) however.. is the converse true? thx

    What is the probability of a tie when two individuals flip biased coins?

    First of all, the question is not clear. "they record the number of flips needed until heads show up" How many heads we are talking about? do they stop recording when the first head appears? In any case, here is hint.. why don't you start with the same probabilities for the boy and...
