No, this is no use in computing the physical area of the sensor

But earlier, you wrote:

>>> Focal Length: 4.5mm (35mm equivalent 37mm)
This is the data you need to compute sensor size. By dividing 37 by

4.5, we find a crop factor equal to 8.2 - so the diameter of your

camera's sensor is 5.3 mm - which means the imager's dimensions is

something like 4.24 mm x 3.18 mm.

I've never heard the term "aperture angle", so I am not sure what sort

of formula this would be.

But if you want to know the angle "seen" by your camera's - that

particular datum is usually called "field of view" (FOV) and depends

on focal length and sensor diameter (but not on aperture). You'll

find the formula explained on this webpage:

For your camera, the FOV a f=4.5mm is atan(5.3/2/4.5), which is

1.064 radians or ~ 61 degrees. It is the same FOV that a lens

with f=35mm lens would have with a 24x36 mm imager.
