Image rotating and superimposing apparatus.

摘要

Using an endoscope system, a surgeon (A) holds an endoscope (2) with a TV camera (hereinafter, an endoscope) and a therapeutic appliance such as forceps and carries out a surgical procedure while viewing a first monitor (4). A surgeon (B) holds a therapeutic appliance such as forceps and carries out the surgical procedure while viewing a second monitor (7). A video signal sent from the TV camera of the endoscope (2) is fed to and processed by an image processing apparatus (8), and displayed on each of the first and second monitors (4 and 7). The image processing apparatus (8) supplies the video signal sent from the endoscope to each of an image inverting circuit (11) and selector switches (12 and 13). The image inverting circuit (11) inverts an image (laterally (to produce a mirror image), vertically, or vertically and laterally (180 DEG )), and supplies a processed video signal to each of the selector switches (12 and 13). Each of the selector switches (12 and 13) selects a video signal to be supplied to each of the first and second monitors (4 and 7), which are display units, in response to a control signal sent from a selector (14). The contents of processing to be performed by the image inverting circuit (11) and the video signal to be selected by the selector (14) are designated using setting switches on an operation panel (15).
