Homework Help: Object is 1000 feet away, how many pixels on my monitor will it be?

  1. Feb 22, 2010 #1
    I need to determine how many pixels on my 72 dpi computer monitor an object will be taken from a camera with the following specs:
    1/4" interlaced CCD
    3.5mm to 91mm focal length
    F1.6 to F4.0
    26x optical zoom
    angle of view: 1.7 degrees to 47 degrees
    resolution: 704x576

    I'm not to0 familiar with cameras or this topic. I thought that calculating the visual angle, V, of the object would help (http://en.wikipedia.org/wiki/Visual_angle) but I'm not sure what to do next. V = 19.70 degrees.
