Abstract:
1. An image capturing apparatus comprising: an image sensor for generating an image signal related to a subject image; photographing control means for performing a photographing operation in which an exposure of the image sensor is divided into a plurality of exposures which divide a total exposure time; addition means for adding sequentially the image signals obtained at each exposure in the photographing operation; amplification ratio calculation means for calculating an amplification ratio of the image signal added by the addition means based on a current accumulated exposure time which is less than the total exposure time; amplification means for amplifying the image signal added by the addition means by using the amplification ratio to compensate for insufficient exposure for the total exposure time; and display control means for displaying information related to the image signal amplified by the amplification means on a display section, the display control means displaying noise information indicating a current amount of noise accumulated in the image signal, the noise information including a noise display graph displaying a value of the current amount of noise; wherein the photographing control means ends the photographing operation when detecting an end instruction operation performed by a user, and determines that the image signal amplified by the amplification means is a captured image obtained by performing the photographing operation with the total exposure time.
