Abstract
In a camera with a finder device which is capable of diopter adjustment, a visual axis detection unit detects the visual axis direction and the fundus imaging state of an observer, a multi-distance measurement unit measures distances to a plurality of points in a photographing frame, a diopter driving unit adjusts the imaging position, and a diopter controller drives the diopter driving unit in accordance with the outputs from the visual axis detection unit and the multi-distance measurement unit. Therefore, since diopter correction is attained based on distance measurement information corresponding to visual axis information, a finder image in which an object at an observation position of an observer is always in focus can be realized.
