Abstract
A processor device includes an image signal acquiring unit, an image processing unit, and a display control unit. The image signal acquiring unit acquires a digital image signal corresponding to an observation mode from an endoscope. The image processing unit includes a region-of-interest-detection-mode image processing unit. The display control unit sets an emphasized region having a larger area than a region of interest and including the region of interest, displays the emphasized region in a manner of emphasized display, and determines whether or not to change setting of the emphasized region in accordance with an amount of variation of the region of interest.
Claims11
A medical image processing apparatus comprising:
- a processor configured to function as:
- a medical image acquiring unit that acquires a medical image through imaging of an observation target;
- a region-of-interest detecting unit that detects a region of interest in the observation target from the medical image acquired by the medical image acquiring unit;
- and
- a display control unit that sets an emphasized region having a larger area than the region of interest and including the region of interest and that displays the emphasized region in the medical image in a manner of emphasized display,
- wherein the display control unit determines whether or not to change setting of the emphasized region in accordance with an amount of variation of the region of interest in the medical image,
- wherein the display control unit sets a reference region on an outer side of the region of interest and an inner side of the emphasized region when setting the emphasized region, and resets the emphasized region and the reference region in a case where at least a part of the region of interest has shifted to an outside of the reference region, and
- wherein the display control unit does not reset the emphasized region and the reference region in a case where the region of interest has shifted within the reference region.

An endoscope system comprising:
- a light source device that emits illumination light for illuminating an observation target;
- an endoscope having an imaging device that performs imaging of the observation target illuminated with the illumination light;
- a processor configured to function as:
- a medical image acquiring unit that acquires a medical image, the medical image being obtained through imaging of the observation target performed by the imaging device;
- a region-of-interest detecting unit that detects a region of interest in the observation target from the medical image acquired by the medical image acquiring unit;
- a display control unit that sets an emphasized region having a larger area than the region of interest and including the region of interest and that displays the emphasized region in the medical image in a manner of emphasized display,
- wherein the display control unit determines whether or not to change setting of the emphasized region in accordance with an amount of variation of the region of interest in the medical image,
- wherein the display control unit sets a reference region on an outer side of the region of interest and an inner side of the emphasized region when setting the emphasized region, and resets the emphasized region and the reference region in a case where at least a part of the region of interest has shifted to an outside of the reference region, and
- wherein the display control unit does not reset the emphasized region and the reference region in a case where the region of interest has shifted within the reference region;
- and
- a display device that displays the medical image to which the emphasized display is applied.

A method for operating a medical image processing apparatus, comprising following steps performed by a processor:
- acquiring a medical image, the medical image being obtained through imaging of an observation target performed by an imaging device;
- detecting a region of interest in the observation target from the medical image;
- setting an emphasized region having a larger area than the region of interest and including the region of interest;
- displaying the emphasized region in the medical image in a manner of emphasized display;
- determining whether or not to change setting of the emphasized region in accordance with an amount of variation of the region of interest in the medical image;
- setting a reference region on an outer side of the region of interest and an inner side of the emphasized region when setting the emphasized region, and resetting the emphasized region and the reference region in a case where at least a part of the region of interest has shifted to an outside of the reference region;
- and
- not resetting the emphasized region and the reference region in a case where the region of interest has shifted within the reference region.
