1. A medical control apparatus to which an endoscope having an insertion portion to be inserted into a subject is detachably connected, the medical control apparatus being configured to perform image processing on a captured image obtained by capturing a subject image introduced by the endoscope and generate a medical photographic image to be displayed on a display device that displays images, the medical control apparatus comprising:
a control circuit configured to
acquire a mask width that is a distance between boundary points dividing the subject image included in the captured image and a mask area that is an area other than the subject image,
calculate a first parameter used for the image processing in accordance with the mask width, and
use the first parameter to perform control such that the smaller the mask width, at least one of
the greater a digital gain in the image processing,
the higher a noise reduction level in the image processing,
the higher a shading level in the image processing,
the greater a set value of black level adjustment in the image processing, and
the lower an enhancement level in the image processing.
