Processing speed is function of capturing frequency


When measuring the processing time in ImageProcessor, it changes by the FPS rate of the corresponding video input device.
My laptop webcam does 30-31 FPS in the daylight, ImageProcessor running in 14 ms and 5-6 FPS at night when ImageProcessor runs in 20 ms with the same algorithm.
I also changed the input image to a static picture loaded from the hard drive but I am observing the same.
It is strange, because sleep times or anything is excluded from the measuring, only the search algorithm is clocked.

May be of locks?
