Abstract

A method whereby a second display device is simulated using software so that images may be directed by a personal computer or other electronic device to appear on the simulated display. The software may then be configured to display images directed to such a simulated display in a portion of the primary display, allowing the user of the method to monitor the simulated display and capture images from the simulated display using an automated capture algorithm to capture and store the image for future use. The presenter or user of the method may make adjustments to the capture parameters, via a control interface, which is viewed on the primary display device.

Claims

1. A system for creating a simulated second display and capturing and storing images from the simulated display comprising:

a computing device comprising a processor, a storage system, and graphics control circuitry capable of connection to at least two computer display monitors;

a first primary computer display monitor, capable of being connected to said graphics control circuitry, associated with and in electronic communication with said computing device for display of information contained in said graphics control circuitry;

a simulated second computer display monitor in simulated connection with said graphics control circuitry when such second computer display monitor is not actually connected to said computing device; and

an image capture device in electronic communication with said computing device which monitors a stream of images directed from the computing device to said simulated second display monitor and stores one or more individual images upon the satisfaction of predetermined capture conditions before each storage.

2. The system of claim 1, wherein:

said capture conditions comprise a change to the monitored images which exceeds a predetermined amount.

3. The system of claim 2, wherein:

said capture conditions further comprise, after said initial change, the monitored images remaining predominantly unchanged for a period of time.

4. The system of claim 2, wherein:

said capture conditions further comprise a predetermined period of time that elapses between each image storage.

5. The system of claim 1, further comprising:

an audio recording device connected to and in electronic communication with said computing device where an audio recording may be captured simultaneously with said storage of one or more images.

6. The system of claim 5, wherein:

said audio recording device further comprising the capability of recording a stream of video images is connected to and in electronic communication with said computing device where a video recording is captured simultaneously with said storage of one or more images.

16. A method comprising the steps of:

capturing and storing images from the graphics control circuitry of the system of claim 1 when the following conditions are present;

an image has changed by a user selectable amount;

a user selectable period of time has passed since the last image was captured; and

the image is not currently undergoing a substantial change.

17. A method of comprising the steps of:

capturing and storing images from the graphics control circuitry of the system of claim 5;

simultaneously capturing audio recordings from the audio recording device of claim 5; and

storing the images and audio recordings in a manner that permits the stored images to be displayed in synchronization with a replay of the audio recordings.

18. The method of claim 17, further comprising the steps of:

simultaneously capturing video recordings from the video recording device of claim 6; and

storing said images and video recordings to be stored in a storage device in such a manner that they may be replayed such that said stored images are displayed in synchronization with replay of the video recordings.

7. A method of simulating a computer display monitor, comprising the steps of:

connecting electronically a graphics control circuitry to at least one simulated computer display monitor which is not connected to the system; and

communicating information comprising a signal or command to said graphics processing circuitry which causes said graphics processing circuitry to send data of images to said simulated computer display monitor, as viewed from a primary display monitor that is connected to said graphics control circuitry.

8. The method of claim 7, further comprising the steps of:

monitoring a stream of images present in the portion of said graphics control circuitry associated with said simulated computer display monitor; and

capturing and storing an image from such stream of images when a predetermined amount of change is detected in the image being monitored.

9. The method of claim 8, wherein:

said amount of change required before said image is captured is variable.

10. The method of claim 8, further comprising the step of:

waiting for an image to remain predominantly unchanged for a period of time before said image is captured and stored.

11. The method of claim 10, wherein:

said amount of time that an image remains predominantly unchanged prior to capture is variable.

12. The method of claim 8, further comprising the step of:

waiting for a predetermined period of time to elapse after capturing and storing of an image before the start of the capture and storage process for an additional image.

13. The method of claim 12, wherein:

said amount of time elapsing before the start of the next capture and storage steps is variable.

14. The method of claim 8, further comprising the step of:

displaying a user interface on a computer display monitor associated with and in electronic communication with said system, which includes a representation of the last image captured and stored.

15. The method of claim 14, further comprising the step of:

displaying, in said user interface, variables which are adjustable to vary the parameters of said image capture method.
