Abstract: A medical control apparatus to which a rigid endoscope having an insertion portion to be inserted into a subject is detachably connected is configured to perform image processing on a captured image obtained by capturing a subject image introduced by the rigid endoscope and generate a medical photographic image to be displayed on a display device that displays images. The medical control apparatus includes: a detection unit configured to detect 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; and a control unit configured to calculate a first parameter used for the image processing in accordance with the mask width.

Abstract: An image processing apparatus includes a linear matrix operation unit configured to set a matrix coefficient in accordance with an input image signal, and perform a linear matrix operation on the image signal using the set matrix coefficient.

Abstract: A medical control device includes a display control unit controller configured to display, in a display device configured to display images, a medical image generated from an imaging signal generated by an imaging device configured to receive light coming from an observation target; and a brightness controller configured to control the brightness of the imaging signal in such a way that the display controller displays the medical image having a predetermined brightness. When the dynamic range of the display device is set to a second value that is greater than a first value, the brightness controller is configured to perform control to lower the brightness of the imaging signal as compared to the brightness of the imaging signal for displaying the medical image at the predetermined brightness when the dynamic range is set to the first value.
