ABSTRACT:
The present invention comprises a distance measuring unit for measuring distances to subjects existent in specific areas within a photographic angle of view, a memory for storing distance measurement information representing measured distances from the camera to at least two subjects existent at different distances the distance measuring unit provides, a specifying unit for specifying positional relationships of at least two subjects to the camera, a display interlocked with specification of the specifying unit and helping an user recognize the positional relationships the specifying unit provides, an arithmetic logic unit for computing the distance measurement information and positional relationships to calculate an inclination of a photographic optical system necessary for producing an image in which at least two subjects are in focus, and a drive for tilting the photographic optical system according to an output of the arithmetic logic unit. Alternatively, this invention comprises an arithmetic logic unit for computing the distance measurement information and positional relationships to calculate angles of the subjects relative to the center axis of the camera, and at least two flashtubes for varying quantities of flashlight according to the information the arithmetic logic unit provides, and thus exposing the subjects to light optimally.
