Abstract
A digital enhancement method enhances a subsection of video. Video is received by a receiver from a sender. The video includes information or displaying a video image. The subsection of the video for digital enhancement is selected. The selecting the subsection of the video for enhancement includes partitioning the video image into the selected subsection and a remainder unselected subsection. The selected subsection is digitally enhanced by the sender to provide the video including a digitally enhanced subsection. The video including the digitally enhanced subsection is received by the receiver from the sender.
Claims38
A digital enhancement method for enhancing a subsection of video, the method comprising:
- receiving video by a receiver from a sender, the video including information for displaying a video image;
- selecting the subsection of the video for digital enhancement, the selecting the subsection of the video for enhancement including partitioning the video image into the selected subsection and remainder unselected subsection;
- digitally enhancing the selected subsection by the sender to provide the video including a digitally enhanced subsection;
- and
- receiving the video including the digitally enhanced subsection by the receiver from the sender;
- wherein
- the video has a first video information density measurable by bits per area, the first video information density describing an amount of video information used to represent an area of the video, the selected and unselected subsection of the video having the first video information density prior to the digitally enhancing the selected subsection by the sender;
- and
- the digitally enhancing the selected subsection includes generating the video including the selected subsection having a second video information density and unselected subsection having a third video information density, the second video information density being greater than the third video information density to provide greater detail in the selected subsection of the video image.

A system for enhancing a subsection of video, the system comprising:
- a user interface;
- a video source;
- a sending unit including a video region enhancer encoder, the video region enhancer encoder being coupled to receive the video from the video source, the video region enhancer encoder being coupled to receive video region enhancer window selection notifications from the user interface, the video region encoder digitally enhancing a selected subsection of the video responsive to the selected subsection being selected by a video region enhancer decoder;
- a receiving unit including the video region enhancer decoder, the video region enhancer decoder being coupled to receive the video from the video region enhancer encoder, the video region enhancer decoder partitioning the video into a selected subsection and an unselected subsection responsive to receiving a selection notification, and transmitting information regarding a position of the selected subsection to the video region enhancer encoder.

A method for enhancing a region of video, the method comprising:
- selecting a region of video for digital enhancement, the selecting the region of video for enhancement including defining a selected region of the video and a remainder unselected region of the video such that the video consists of the selected region and the unselected region;
- and
- digitally enhancing the selected region;
- wherein
- the video has a first video information density measurable by bits per area, the first video information density describing an amount of video information used to represent an area of the video, the selected and unselected regions of the video having the first video information density prior to the digitally enhancing the selected region;
- and
- the digitally enhancing the selected region includes generating the video including the selected region having a second video information density and the unselected region having a third video information density, the second video information density being greater than the third video information density to provide greater detail in the selected region.

A method for enhancing a subsection of video, the method comprising:
- receiving video by a receiver from a sender, the video including information for displaying a video image;
- selecting the subsection of the video for digital enhancement, the selecting the subsection of the video for enhancement including partitioning the video image into the selected subsection and a remainder unselected subsection;
- and
- receiving the video by the receiver from the sender after selecting the subsection of the video, the video including a digitally enhanced subsection corresponding to the selected subsection after selecting the subsection of the video;
- wherein
- the video has a first video information density measurable by bits per area, the first video information density describing an amount of video information used to represent an area of the video, the selected and unselected subsections of the video having the first video information density prior to the partitioning;
- and
- the digitally enhanced subsection has a second video information density and the unselected subsection has a third video information density, the second video information density being greater than the third video information density to provide greater detail in the selected subsection.
