Abstract
A camera has a viewfinder that forms a subject image to be observed, a multipoint auto-focus adjuster that focuses the subject image on the basis of multiple focus points defined on the subject image, a superimposer that superimposes an indicator mark on a position of a given focus point, and a focus point luminance detector that detects a luminance of the position. Then, the superimposer superimposes the indicator mark such that a brightness of the indicator mark increases as the luminance of the position increases.
