the image will be displayed in the GalaxyView acquisition GUI.
2)
When the device is in the acquisition mode, click "Acquisition of Brightfield image" to complete the
bright field image acquisition.
3)
The number of bright field images acquired is related to the Acquisition Frame Count. For example, if
the number of Acquisition Frame Count is set to 4, when you click "Acquiring of Brightfield Image", 4
images will be acquired for FFC calculation.
4)
If the brightness of the acquired bright field image is less than 20, the prompt box will show "The bright
field image is too dark, it will affect the flat field correction effect, it is recommended to adjust the
brightness of the image in the range of 20-250" and then re-acquiring the bright field image.
5)
If the brightness of the acquired bright field image is greater than 250, the prompt box will show "The
bright field image is too bright, it will affect the flat field correction effect, it is recommended to adjust
the brightness of the image in the range of 20-250" and then re-acquiring the bright field image.
1)
The larger the "Acquisition Frame Count" is set, the longer it will take to acquire the bright
field images.
2)
When the color camera is acquiring bright field images, if white balance has not been done,
the image after FFC is an image with white balance effect.
9.2.2.3.
Execute FFC
1)
"Execute FFC" is enabled after the bright field image acquisition is completed.
2)
Click "Execute FFC" to calculate the FFC factor and set it to the device to take effect in real time. If
the factor is not written to the device, it will be lost when the device is powered down. And the FFC
needs to be redone.
3)
When the FFC is completed, the preview widget takes effect. The preview function can be used to
check the effects before and after the FFC.

1)
When reading FFC data from the device or writing FFC data to the device, the FFC is enabled by
default. After the read from the device is successful, the FFC takes effect in real time.
2)
When writing to the device, the user set will be saved and the startup user set will be set to userset0.
