    Hi all,

    As part of the design of CMOS sensor I want to calculate its size and I found the following equation :

    A=(Y*N)/T with:

    A: Sensor size (in pixels)
    Y: field of view
    N: number of pixels assigned to the Body to be filmed
    T: size of the smallest detectable body

    my question is this the correct formula to calculate the size ?

    Doesn´t look correct to me, or actually, what is the unit of filed of view?

    What are the units of all of them?
    A = width / height / total number of pixels?
    etc
    What bodies are you talking about?

    the body is the retina and its unit is mm
    the smallest part detectable in the retina its unit is µm
    the number of pixels not yet determined

    A simple unit check will show that this cannot be correct:
    number of pixels = number of pixels * degrees / meters
    Field of view would have to be in meters for this to be of any sense.
