摘要： 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.

摘要： An image processing apparatus includes a processor including hardware. The processor is configured to: execute a first white balance adjustment on a first signal corresponding to multiple wavelength bands; generate a luminance signal from a second signal including an area having saturation caused by the first white balance adjustment; extract a detail component based on the first signal; and apply the detail component to the luminance signal to generate a corrected luminance signal.
