The method automatically captures images using a change detection algorithm and stores those images in digital form for future use. The presenter or user of the method may make adjustments to the parameters, via a control interface, used by the algorithm to determine when to capture and store a static image from the graphics control circuitry. ## Claims ### Claim 1 A system for capturing and storing images from a computing device comprising: a computing device comprising a processor, a storage system, and graphics control circuitry; at least one computer display monitor that is associated with and in electronic communication with said computing device for display of information contained in the graphics control circuitry; and an image capture device in electronic communication with said computing device which monitors a stream of images communicated from the computing device to a computer display monitor in electronic communication with the computer device and stores one or more individual images upon the satisfaction of predetermined capture conditions before each storage. ### Claim 2 (depends on 1) The system of claim 1, wherein: said capture conditions comprise a change to the monitored images which exceeds a predetermined amount. ### Claim 3 (depends on 2) 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. ### Claim 4 (depends on 2) The system of claim 2, wherein: said capture conditions further comprise a predetermined period of time that elapses between each image storage. ### Claim 5 (depends on 1) 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. ### Claim 6 (depends on 5) 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. ### Claim 7 (depends on 1) A method of automatically capturing and storing images, comprising the steps of: monitoring a stream of images present in the graphics control circuitry of the system of claim 1; and capturing and storing an image from said stream of images when a predetermined amount of change is detected in the image being monitored. ### Claim 8 (depends on 7) The method of claim 7, wherein: said image is captured from the portion of said graphics control circuitry associated with a computer display monitor connected to the computing device where said computer display monitor is selectable from among computer display monitors connected to said graphics control circuitry. ### Claim 9 (depends on 7) The method of claim 7, wherein: said amount of change required before said image is captured is variable. ### Claim 10 (depends on 7) The method of claim 7, 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. ### Claim 11 (depends on 10) The method of claim 10, wherein: said amount of time that an image remains predominantly unchanged prior to capture is variable. ### Claim 12 (depends on 7) The method of claim 7, 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. ### Claim 13 (depends on 12) The method of claim 12, wherein: said amount of time elapsing before the start of the next capture and storage steps is variable. ### Claim 14 (depends on 7) The method of claim 7, 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. ### Claim 15 (depends on 14) 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. ### Claim 16 (depends on 1) 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. ### Claim 17 (depends on 5) 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. ### Claim 18 (depends on 6, 17) The method of claim 17, further comprising the steps of: simultaneously capturing video recordings from the 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.
