The Video Overlay Monitoring System (VOLMS) superimposes vital signs from a monitor onto images for medical use. Image quality attained by the camera component as well as the recording and playback components of VOLMS was evaluated.<br/> Based on the measurement using test charts, the resolution of a camera for an overall view of surgery and that of an intraoral camera were 320 to 350. While an object of 2.5 mm or larger could be identified at a distance of 70 cm in the overall view, an object of 90 micrometers or larger at a distance of 21 mm could be identified by the intraoral camera. The resolution of a still video recorder and that of a printer were 450 to 500. Due to VTR's low resolution of 270, the overall system resolution was decreased. Blue chroma of the intraoral camera was low and its luminance was generally high, which was no problem for clinical use. Both chroma and luminance of the recording and playback components were satisfactory. The standardized pictures of implant placement to superstructure setting clearly showed wound healing around the implant. In this care, any changes in vital signs suggestive of general infection were not observed even in the inflammation period.<br/>
