Abstract

A method and system for accessing visually obscured data in a data processing system having a computer application displayed concurrently with a video image in a window which partially overlaps the computer application. The location of the video image within the window is maintained in relation to the visually obscured data within the computer application. The video image, which is comprised of a plurality of lines of video data, is then temporarily altered to a translucent state by omitting selected lines of video data. This renders the video image partially visible, allowing the visually obscured data within the computer application to be seen through the video image. The visually obscured data may now be visually accessed through the video image.

Claims

1. A method in a data processing system for accessing visually obscured data within an application displayed on a display screen, wherein a video image including a plurality of successive lines of video data is displayed substantially throughout a window displayed on said display screen, wherein said window partially overlaps said application and overlies said visually obscured data, said method comprising the steps of:

maintaining the relative location of said video image within said window in relation to said visually obscured data within said application; and

temporarily altering said video image within said window to a translucent state by omitting selected ones of said plurality of successive lines of video data, wherein said video image and said visually obscured data within said application are substantially visible throughout said window and wherein said visually obscured data within said application may be viewed through said video image.

2. The method in a data processing system for accessing visually obscured data according to claim 1, wherein said plurality of successive lines of video data include a plurality of odd numbered lines of video data and a plurality of even numbered lines of video data and wherein said step of omitting selected lines of video data comprises omitting said plurality of even numbered lines of video data within said video image.

3. A data processing system for accessing visually obscured data within an application displayed on a display screen, wherein a video image including a plurality of successive lines of video data is displayed substantially throughout a window displayed on said display screen, wherein said window partially overlaps said application and overlies said visually obscured data, said data processing system comprising:

means for maintaining the relative location of said video image within said window in relation to said visually obscured data within said application; and

means for temporarily altering said video image within said window to a translucent state by omitting selected ones of said plurality of successive lines of video data, wherein said video image and said visually obscured data within said application are substantially visible throughout said window and wherein said visually obscured data within said application may be viewed through said video image.

4. The data processing system for accessing visually obscured data according to claim 3, wherein said plurality of successive lines of video data include a plurality of odd numbered lines of video data and a plurality of even numbered lines of video data and wherein said means for temporarily altering said video image comprises means for omitting said plurality of even numbered lines of video data within said video image.
