an illumination apparatus configured to illuminate probe light;

an image sensor;

a camera controller configured to control a timing at which the illumination apparatus illuminates the probe light and a timing at which the image sensor is exposed, such that the image sensor outputs a slice image for each of image capture ranges divided in the depth direction while changing the image capture range, and such that each slice image includes only an object included in the corresponding image capture range; and

one or more processors configured to generate a final image including an entire object of interest based on the plurality of slice images that correspond to the plurality of image capture ranges

wherein the final image includes only the object of interest.
