4.11.2 How to correct
(1) Remove the lens cap and place a white object. Then you can acquire user white
correction data. With a lens, the shading by both the lens and the light source will
be simultaneously corrected. At this time, please defocus a little to avoid being
affected by the non-uniformity of the object.
(2) Send the
“wht
CR
” command through serial communication.
(3) Confirm that the camera returns
“>OK” and “>wht”. Thus user white correction
data is saved and loaded to the camera.
(4) Send the
“shc 2 VAL
CR
” command through serial communication. Then the user
white correction will be on and set the correction level as
“VAL”.
