light intensity range from labview

Solved!
Go to solution

Hi,

I have been using the "light meter" module to measure the light intensity from a camera. I found out the range is from 2 to 260. I wonder if there is a way to maximize the range? Say increase to 300 from 260?

Thanks

Hmm, might the max be 256?  As in 8-bit binary?

While I'm with Bob .. about the U8 light value ...

to increase the value range just multiply with a gain factor 🙂 

gain=($desired_max_value)/($actual_max_value)   ( = 300/255 ??)

However the resolution is still U8  😄

Hi Bob,

Yeah! It is an 8bit image so it is 256. It now makes sense to me.

Thanks

Thanks Henrik! That's a good idea. Since the grey intensity shows two more digit after the decimal, it would at least look nice when multiple a big number.
