:CAMEra:CALIbrate
When RED GEEN and BLUE is measured with the 2D imager and with the
spectrometer calibration can be done with this command.
Example:
Write
:CAMEra:CALIbrate
ASCII CRLF

Not Applicable
After this command a 3x3 matrix is converted which transform the RGB
space of the camera into XYZ space. Due to this method accuracy for
colour and luminance is very high.
After this command is given the engine will transform the WHITE, RED,
GEEN and BLUE image to XYZ. These XYZ images then can be used in
the calculation commands with their corresponding names.
7.5.4
:CAPTure:XYZImage
After finding the display and calibrating the Atlas 2D imager the real
measuring can start. When this command is given the imager takes a
image, transforms it to XYZ automatically and stores it in the engine. The
XYZ image is stored under the name CAPIMG, which stands for CAPtured
IMaGE. With other commands calculations, like mura or uniformity, can be
done on the XYZ image. Example:
Write
:CAPTure:XYZImage CAPIMG
ASCII CRLF

Pass
ASCII CRLF
Returned result is pass or fail.
7.5.5
:GET:XYZImage
With this command it is possible to get all 2D XYZ data, this enables the
user to use its owns algorithms on the 2D image. The first read is the data
size of the image. The data size of the data is send back according the set
Virtual Resolution times 3 for the XYZ and times 4 for the format The data
is send back as a flattened string with asingle float format (4 bytes).
Example: Display settings for Virtual Resolution are 5 and 4 (horizontal
and vertical).
