To improve user-friendliness when checking the depth of field, in a camera system having an aperture value alteration function. A camera system (100) has an imaging optical system (L), an imaging unit (45), an aperture adjustment unit (29), a liquid crystal display monitor (16), and an AGC unit (59) of an analog signal processing unit (51). The imaging optical system (L) forms an optical image of a subject. The imaging unit (45) converts the optical image into an image signal, and obtains an image of the subject. The aperture adjustment unit (29) can adjust the aperture value of the imaging optical system. The liquid crystal display monitor (16) displays the image. The AGC unit (59) adjusts the brightness of the image displayed on the liquid crystal display monitor (16) according to the aperture value.
