Abstract: Provided is a distance measuring apparatus that can cope with the problem of wrong distance measuring attributable to the presence of miscellaneous subjects and minimize the possibility of defocused photographing. In this distance measuring apparatus, passive-type distance measuring is carried out in accordance with a subject image signal for the central portion of a view field. Signal light for distance measuring from an infrared-emitting diode is projected on a subject in the central portion of the view field, and active-type distance measuring is carried out by means of a sensor array in accordance with reflected signal light reflected by the subject. According to the output result of the passive-type central distance measuring, a CPU determines whether or not to effect distance measuring for the peripheral portion of the view field based on an image signal for the peripheral portion.
