A medical image processing apparatus comprising: a medical image acquiring unit that acquires a medical image obtained by capturing an image of an observation target; a region-of-interest detecting unit that detects a region of interest from the medical image; and a display control unit that causes a display unit to display report information and the medical image, the report information reporting that the region of interest has been detected; characterized in that : the display control unit changes a display manner of the report information by using a detection state of the region of interest and an elapsed time after change of the detection state, wherein the display control unit changes the display manner of the report information by referring to an elapsed time after the detection state of the region of interest has transitioned from a detected state in which the region of interest is detected and is visible on the display unit to an undetected state in which the region of interest is not detected and is not visible on the display unit , and wherein the display control unit causes the display to display the elapsed time as the report information, the elapsed time being a time after the detection state of the region of interest has transitioned from the detected state to the undetected state. a medical image acquiring unit that acquires a medical image obtained by capturing an image of an observation target; a region-of-interest detecting unit that detects a region of interest from the medical image; and a display control unit that causes a display unit to display report information and the medical image, the report information reporting that the region of interest has been detected; characterized in that : the display control unit changes a display manner of the report information by using a detection state of the region of interest and an elapsed time after change of the detection state, wherein the display control unit changes the display manner of the report information by referring to an elapsed time after the detection state of the region of interest has transitioned from a detected state in which the region of interest is detected and is visible on the display unit to an undetected state in which the region of interest is not detected and is not visible on the display unit , and wherein the display control unit causes the display to display the elapsed time as the report information, the elapsed time being a time after the detection state of the region of interest has transitioned from the detected state to the undetected state. the display control unit changes a display manner of the report information by using a detection state of the region of interest and an elapsed time after change of the detection state, wherein the display control unit changes the display manner of the report information by referring to an elapsed time after the detection state of the region of interest has transitioned from a detected state in which the region of interest is detected and is visible on the display unit to an undetected state in which the region of interest is not detected and is not visible on the display unit , and wherein the display control unit causes the display to display the elapsed time as the report information, the elapsed time being a time after the detection state of the region of interest has transitioned from the detected state to the undetected state. <EOS>
