4.11.1 Command Settings
Send commands from PC via serial communication to turn on/off all pixel bit
correction and acquire correction data.
Example of command setting
ffcm 0: Factory black corr factory white correction (factory default)
ffcm 1: Factory black corr optional white correction
blk: Get optional black correction data
wht: Get arbitrary white correction data
4.11.2 How to correct
(1) Remove the lens cap to make the subject uniformly white. This will allow you to
obtain the arbitrary white correction data. With the lens on, the shading of the lens
and the light source will be corrected at the same time, but the shading of the
subject will be directly reflected, so please shift the focus.
(2) Send "wht CR" through the COM port.
(3) Confirm that ">OK" and ">wht" are returned from the camera. This will write the
arbitrary white correction data into the flash memory and then expand it into the
camera's memory.
(4) Send "ffcm 2 CR, ffct 800 CR" through the COM port. This will turn on the
arbitrary white correction and set the correction level to "800".
