Image calibration based on a calibration mark on a calibration image marking a calibration event or event type matching with a current calibration operation

An image forming apparatus, comprising:

• a memory, storing a computer program for performing an image calibration method;
• and
• a processor, coupled with the memory and when the computer program being executed, configured to:
• output a calibration image in response to a calibration instruction inputted by a user, wherein the calibration image includes a calibration pattern and a calibration mark;
• and the calibration mark is configured to mark a calibration event or a calibration event type corresponding to the calibration image;
• according to the calibration mark of the calibration image, determine whether the calibration event corresponding to the calibration image matches a calibration event corresponding to a current calibration operation, or determine whether the calibration event type corresponding to the calibration image matches a calibration event type corresponding to a current calibration operation, wherein the calibration event includes one or more selected from
• count information configured to characterize an encoding order of calibration images or statistical information of an image forming apparatus;
• serial number information configured to characterize a serial number corresponding to the image forming apparatus;
• and
• random sequence information configured to characterize uniqueness of the current calibration operation;
• and
• perform image calibration according to the calibration pattern in the calibration image in response to a determination that the calibration event corresponding to the calibration image matches the calibration event corresponding to the current calibration operation, or in response to a determination that the calibration event type corresponding to the calibration image matches the calibration event type corresponding to the current calibration operation.
