Abstract
A method, a device and computer readable storage media facilitate detecting a scrolling area within digital content comprising a plurality of frames, wherein the detection includes a comparison between a current frame and a previous frame to determine at least one location within the current frame in which pixel values change in relation to a corresponding location of the reference frame, searching for a reference line of pixels within the scrolling area of the previous frame, in response to finding a reference line, searching for a corresponding matching line of pixels in the current frame that matches the reference line, and, in response to finding a corresponding matching line of pixels in the current frame, determining a degree of scrolling of content in the scrolling area of the current frame in relation to the previous frame.
