An imaging apparatus includes a viewfinder optical system that observes a subject image input from a photography optical system. The imaging apparatus also includes a transmissive member upon which is provided a line image indicating detection positions of photography supporting information relating to photography conditions, within a photography region. The photography conditions are at least one of setting information relating to a focus and setting information relating to an exposure. The imaging apparatus further includes an imaging device that acquires a photographed image relating to the subject image, the line image having been superimposed on the photographed image. In addition, the imaging apparatus includes a processing unit that corrects a part of the line image extracted from the line image shown in the photographed image, the part of the line image having been extracted corresponding to the photography conditions that have been set.
