For example, even if the same medical video source and output source are used, if the operating light is set to a warm color, image processing functions such as sharpening filters and brightness enhancement filters are turned off, and the operating light is set to a cool color. At times, you can add image processing settings such as turning on image processing features such as sharpening filters and brightness enhancement filters.

  • Image processing settings can be added to turn on. For example, for endoscopic images using an electric scalpel, image processing functions such as sharpening filters and brightness enhancement filters should be turned off, and rotation filters should be turned off when the menu screen is open. Processing settings can be added. In other words, if a rotation filter is applied to an endoscopic image while the menu screen is open, it is assumed that the menu screen will shake or the endoscopic image will not be corrected properly. situations can be avoided.

Furthermore, in the medical image processing control system 11, when the picture-in-picture function is turned on, all image processing is turned off or a filter is applied before the picture-in-picture is generated. It is preferable that Alternatively, image processing settings may be set in detail depending on the combination of two medical video sources and one output source that are picture-in-picture targets.
