Abstract

Computer screen contents and accompanying audio are captured by a method, embodiments of which are implemented by a specialized apparatus. Embodiments of the method include capturing an image of the computer screen contents at predetermined time intervals and determining one or more changes between a current captured image and a previous captured image. The method also includes modifying color data associated with a changed region of the current captured image and encoding the modified color data for the changed region.

Keywordsscreen capture; computer screen; image processing; time lapse; pixels
