Imaging apparatus capable of readily specifying undesirable photographing parameters form auto photographing parameters

An imaging apparatus comprising:

• a parameter determining section that determines a plurality of photographing parameters to be set when a subject is photographed;
• a parameter setting section that sets each value of part of the plurality of determined photographing parameters;
• a moving image acquiring section that acquires a moving image using the part of set photographing parameters;
• a display section that displays the acquired moving image;
• a shutter button that is depressible in two depths to be partly-pressed and fully pressed;
• an evaluation button that evaluates the photographing parameters, the evaluation button being a separate button from the shutter button;
• and
• a parameter changing section that, when the evaluation button is operated while the moving image is displayed, changes at least one of values of the part of set photographing parameters,
• wherein the moving image acquiring section acquires an updated moving image using the changed set of photographing parameters and the display section displays the updated moving image.
