The system can record video from one or more video sources. The system can store the recorded video in a cached memory as stored video. The system can receive a triggering event, such as receiving a signal, operation of an actuator, or issuance of a voice command. In response to the triggering event, the system can capture a video segment from the stored video. Because the video segment is captured from stored video, the video segment can optionally include video and/or frames that occurred before the triggering event is received. ## Claims ### Claim 1 A system for image capture during an internal medical procedure performed within a body of a patient, the system comprising: at least one processor; and memory coupled to the at least one processor, the memory configured to store instructions that, when executed by the at least one processor, cause the at least one processor to execute operations, the operations comprising: recording video from one or more video sources, the recording occurring during the internal medical procedure performed within the body of the patient; storing the recorded video in a cached memory as stored video; performing an analysis of the stored video to detect a specific event, occurring during the internal medical procedure performed within the body of the patient, as a triggering event; and in response to detecting the triggering event, capturing a video segment from the stored video based on an onset and cessation of the triggering event. ### Claim 2 (depends on 1) The system of claim 1, wherein the operations further comprise: prior to receiving the triggering event, buffering one or more segments of the stored video;

and prepending one or more video frames of the cached video stream having a time code occurring prior to the triggering event. ### Claim 4 (depends on 2) The system of claim 2, wherein the operations further comprise: storing a video capture window of time of the recorded video, the video capture window of time including at least a portion of the one or more buffered segments. ### Claim 5 (depends on 2) The system of claim 2, wherein the one or more buffered segments includes a fixed length of the stored video. ### Claim 6 (depends on 2) The system of claim 2, wherein the one or more buffered segments includes a user-modifiable length of the stored video. ### Claim 7 (depends on 2) The system of claim 2, wherein the one or more buffered segments has a length that depends on a recognized event of the medical procedure. ### Claim 8 (depends on 1) The system of claim 1, wherein the specific event is determined based at least in part on information stored in one or more profiles, wherein the analysis of the stored video is performed in real-time to compare the stored video with the information in the one or more profiles, and wherein the triggering event includes an activation by a user, and wherein the internal medical procedure is an endoscopic medical procedure. ### Claim 9 (depends on 8) The system of claim 8, wherein the triggering event includes at least one of: operation of an actuator, or a voice activation. ### Claim 10 (depends on 1) The system of claim 1, wherein the operations further comprise: capturing a plurality of frames of the stored video, the plurality of frames extending over a time window that includes the triggering event, with one or more frames of the plurality of frames occurring before the triggering event and one or more frames of the plurality of frames occurring after the triggering event; and storing one or more still images from the plurality of frames of the stored video. ### Claim 11 (depends on 10) The system of claim 10, wherein capturing the plurality of frames includes selecting the time window based on at least one of: a value controlling a number of active content streams from which images are to be captured, a desired temporal distribution of captured images, a temporal spacing between captured frames of video, a number of captured frames before and after a current frame at time of a valid capture and record request, desired spatial characteristics of captured frames, or combinations thereof. ### Claim 12 (depends on 1) The system of claim 1, wherein the at least one processor is configured to detect the specific medical event based on one or more visual cues in the recorded video, and wherein the one or more visual cues include at least one of smoke, bubbles, a near-lens obstruction, or motion in a field of view of an imaging sensor. ### Claim 13 A system for image capture during an internal medical procedure performed within a body of a patient, the system comprising: at least one processor;
