Pixel Correction

 

 

As a rule, image sensors (CCD, CMOS and so on) have fixed pattern noise 

and photo response non-uniformity. Lens shading and light sources can also 

cause  non-uniformity.

 

The  camera  is  set  to  the  optimal  correction  before 

shipping in order to provide image of the highest grade.     

The  camera  also  has  a  user  white  correction  function  to  cope  with  lens 

shading  and  non-uniform  illumination,  or  to  be  able  to  completely  clear  the 

uneven brightness generated by changing the spectral response level of the 

light source. 

 

Cal_bl: Output data of each pixel at perfectly dark (digital)

 

Cal_wh: Output 

data of each pixel in uniform illumination (digital) Target_Val: Target value for 
correction (10bit digital)

 

Vin :Input data (digital) Vout :Output data (digital)

 

The 

corrected  data  is  expressed  in  the  following  equation.  Vout=(Vin-Cal_bl)  x 
Target_val / (Cal_wh-Cal_bl)
