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 ?

 

please help

 

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

 

its Degree isn't it ?

 

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.
