<p>A system helps filter and correct video captured and streamed from a mobile device. In particular, the system detects and streams content shown on screens, allowing anyone to stream screen content immediately without needing to develop hooks into external software (i.e. without installing a screen recorder software in the computer). The system can use a variety of user-selectable techniques to detect the screen, and utilizes the mobile device's touchscreen to allow users to manually override detected corners. However, some of these approaches could potentially be applied to other types of content, such as identifying TV screens, appliance LCD screens, other mobile devices' screens, multifunction devices. (e.g. a remote technician could help troubleshoot a malfunctioning MFD by having the end-user point his cellphone to the LCD screen of the MFD).</p> |
