1. Steps for Backing up Current Calibration Data


1) Connect the camera to your computer. (Make sure camera is detected in the device manager)

2) Open SDPC_Wizard.exe file on your computer.

3) A Window will open.



4) Click next to continue.
    (Note: If the camera is visible by the computer, then it will go to the next step)
5) The following window will open.



6) To save current calibration, select Backup Current Calibration Data and press Start SDPC Calibration as it is shown below. Save Log File selection is optional.



The Current Calibration Data file will be saved in Documents folder with a name of format SDPC_Backup_Calibration_SN_Date_Time_Year. 

(Note: since the Write New Calibration to Flash was not selected, performed Static Defective Pixel Test data will not be saved into a camera Flash memory.)



2. Steps for Saving Calibration Data


1) Select Save Calibration Data.
     You can change a saving location and the name of the Calibration Data file by pressing on Browse.

    (Note: selecting Write New Calibration to Flash will not load Calibration Data into the camera Flash memory at this stage since Load Calibration Data is not selected.)
2) Press Start SDPC Calibration.
     All of these steps are shown in the image below.




3. Steps for Loading Calibration Data


1) Select Write New Calibration to Flash.
    (Note: Write New Calibration to Flash must be selected or Calibration Data cannot be loaded and an error message will be provided.)
2) Select Load Calibration Data and browse to its location using “Browse” button.
3) Press Start SDPC Calibration.



4. Selective Pixel Correction


The current Calibration Data or a new Calibration Data can be stored in a .csv file inside the Documents folder and loaded to the camera Flash memory later, as it has been shown in the section 2 and 3 of this manual. In addition, the calibration data in the .csv file can be modified and only desired pixels can be corrected. For more information about pixel correction, please refer to the Static Defective Pixel Correction Wizard Guide article that can be found in Pixelink Knowledge Base.
The .csv file can be opened by Microsoft Office Excel or Notepad as it is shown below, where one line represents X, Y, Defective Pixel Type, and Digital Number (DN) Difference for each listed pixel. The SDPC Wizard lists all defective pixels found and orders them by severity. Typically, the maximum number of defective pixels that can be corrected is around 1000. Also, the number of defective pixels found by SDPC Wizard can be verified in the SDPC working window or a saved Log File, if the last one is selected.


Where column A - X, B – Y, C - Defective Pixel Type, and D - DN Difference of a pixel.



For Selective Pixel Correction:


1) Open the .csv file that is created in the section 1 or 2 of this manual.
2) Edit the .csv file by adding, deleting, and/or replacing desired pixels for being corrected as it is shown below.
3) Save the edited .csv file.



4) Load the edited .csv file and write it into the camera Flash memory as it is discussed in the section 3 of this manual. The SDPC Wizard correction result is shown below.
