Running the DCMS application
See the “User Interface, Sensor panel” paragraph above for more details on
the selection of the test patch.
• There is no need to set other parameters as it is the objective of this process
to acquire these from the reference display.
Step 4: The acquisition
• Press ‘Get…’ to open the acquisition dialog.
• Follow the instructions as given in the calibration dialog and press ‘Start’ to
start the acquisition routine.
• During the acquisition routine, the user may interrupt at any time by press-
ing the ‘Close’ button to return to the main application.
• The user is informed of each step of the acquisition in the text area of the
acquisition dialog.
• During acquisition the progress bar is colored blue.
• When the acquisition in finished, the progress bar will display if the acquisi-
tion was successful or not and color green when successful, red if failed. As
soon as this message appears, you may close this dialog box.
• After the routine, the test patch will show a green color if the routine was
successful or red if it failed. Text in the text area of the calibration window
can be copied and pasted into your favorite text editor and saved to file.
White point, mid gray, gamma* and brightness are automatically copied to
the main application window.
• Press ‘Close’ to return to the main application. Pressing ‘Start’ will redo the
routine all over again. If ‘Internal display pattern generator’ was selected,
the display will switch back to the previously selected input when the acqui-
sition dialog is closed.
* Gamma and mid gray luminance may differ slightly if recalculated as gamma is
calculated as a best fit from 8 gray levels between 0 and 255.
Step 5: The target display
• Press ‘Disconnect’ to stop communication with the reference display.
• Physically connect the target display via serial connection to the host. Refer
to the documentation of the display for the serial port pinning.
• Select the display type, serial port number, baud rate and monitor ID
(Default monitor ID is 1) of the target display. Press ‘Connect’ and verify in
the connection status field that the connection to the display says ‘CON-
NECTED’.
Step 6: Set parameters
• Select the type of test patches to be used. Select ‘External computer graph-
ics’ if the host is the input source of the display and you want the want the
test patterns to be created in the calibration dialog. Select ‘Internal display
pattern generator’ when the display has an input source different from the
host. See the “User Interface, Calibration Target Panel” paragraph above for
more details on the selection of the test patch.
• All calibration target values are automatically set during the acquisition rou-
tine on the reference monitor. If needed, changes can be still be made here.
