Abstract: An image pickup apparatus is an image pickup apparatus capable of acquiring an image of an object in gas and in liquid, the image pickup apparatus including: an image pickup optical system; an image pickup device; a controlling portion configured to make an in-gas judgment if a vignetting portion is detected in an image signal and make an in-liquid judgment if a vignetting portion is not detected in the image signal; and a display data generating portion configured to generate certain display data corresponding to in-gas image pickup if the in-gas judgment is made and generate other display data corresponding to in-liquid image pickup if the in-liquid judgment is made.
