Method, apparatus and computer program product for testing a display

An apparatus for testing a display, the apparatus comprising at least one processor;

• and at least one memory including computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
• capture a set of images shown by a display element of the display;
• move the display;
• receive motion information of the movement of the display;
• detect a moment of time of the movement of the display as a first time instance;
• compare contents of at least two images of the set of images to determine whether at least a part of the information shown by the display element has been moved to another location of the display element;
• provide the comparison results as a motion information of the image content;
• detect movement in the set of images on the basis of the motion information of the image content;
• determine the moment of the movement in the set of images as a second time instance;
• and
• determine a motion to photon latency on the basis of the time difference between the second time instance and the first time instance.

A computer program product for testing a display capable of showing images at a first resolution, the computer program product stored on a tangible medium with code thereon for use by an apparatus, which when executed by a processor, causes the apparatus to:

• capture a set of images shown by a display element of the display;
• move the display;
• receive motion information of the movement of the display;
• detect a moment of time of the movement of the display as a first time instance;
• compare contents of at least two images of the set of images to determine whether at least a part of the information shown by the display element has been moved to another location of the display element;
• provide the comparison results as a motion information of the image content;
• detect movement in the set of images on the basis of the motion information of the image content;
• determine the moment of the movement in the set of images as a second time instance;
• and
• determine a motion to photon latency on the basis of the time difference between the second time instance and the first time instance.
