Abstract The present invention comprises a first distance-measuring mode in which a subject distance is measured on the basis of a subject image signal produced by at least a pair of light-receiving elements receiving the light from subjects, a second distance-measuring mode in which the subject distance is measured on the basis of an image signal from which a steady-state light removing section has removed the steady-state light component from the subject image signal, while a projecting source is projecting light onto the subjects, and a CPU which causes the second distance-measuring mode to operate for a specific time and, according to the image signal obtained, selects a subject whose distance is to be measured.
