An imaging control apparatus executes focusing operation for setting an in-focus state of an imaging optical system for an imaging device on an object by using the object image obtained by imaging the object illuminated by an illumination light source by using the imaging device. The imaging control apparatus changes an imaging setting to change the signal-to-noise ratio of the object image between the time of executing the focusing operation and other times. The imaging control apparatus processes the object image so as to maintain the tonality of the image displayed on a display device before and after an imaging setting is changed and displays the processed object image on the display device.
