Abstract:
1. A photography device comprising: an imaging component that images a subject and acquires an image representing the subject; a focusing component that focuses a subject image on an imaging surface of the imaging component; a magnification alteration component that alters a magnification of the subject image focused by the focusing component; a display component that displays the subject image in real time on the basis of information of the image acquired by the imaging component; an acquisition component that acquires a focusing evaluation value representing a degree of focusing of the subject image by the focusing component; a control component that performs focusing control by controlling the focusing component such that the focusing evaluation value acquired by the acquisition component is at a maximum, and controls the magnification alteration component so as to lower a display magnification of the subject image by the display component if the focusing evaluation value is at or below a pre-specified threshold value; and a storage component that stores the focusing evaluation value acquired by the acquisition component, wherein: the control component controls so as to lower the display magnification of the subject image by the display component if the focusing evaluation value acquired by the acquisition component at a current point in time has fallen by at least a pre-specified threshold value from the focusing evaluation value stored by the storage component a predetermined duration before, and the control component increases a degree of the lowering of the display magnification by the display component in accordance with a magnitude of a degree of the fall of the focusing evaluation value.
