Abstract
Disclosed is an image processing method and apparatus. The method comprises: acquiring a reference time code such as a Coordinated Universal Time signal; displaying, on a display (110), a value based on the reference time code; imaging, by a sensor (200), the display (110), thereby generating an image of the display (110); processing, by an image processor, the image including generating, based on the reference time code, a time-stamp for the image; and comparing the value displayed on the display (110) in the image to the time-stamp to determine a latency value. The latency value may be used to correct time-stamps of images capture by the sensor (200) and determined by the image processor.
Claims15
An image processing method comprising:
- acquiring a reference time code;
- displaying, on a display, a value based on the reference time code;
- imaging, by a sensor, the display, thereby generating an image of the display;
- processing, by an image processor, the image including generating, based on the reference time code, a time-stamp for the image;
- and
- comparing the value displayed on the display in the image to the time-stamp to determine a latency value.
An image processing apparatus comprising:
- means for acquiring a reference time code;
- a display configured to display a value based on the reference time code;
- a sensor configured to image the display, thereby generating an image of the display;
- an image processor configured to process the image including generating, based on the reference time code, a time-stamp for the image;
- and
- means for comparing the value displayed on the display in the image to the time-stamp so as to determine a latency value.
