A camera includes a focus-detection module 130 inserted into or withdrawn from an optical path between an image-sensing optical system (152-155) and a CCD image-sensing device (111). An image pick-up signal from the CCD image sensing device (111) is used as ordinary image data for recording when the module (130) is withdrawn from the optical path and as image data for rangefinding when the module (130) is inserted into the optical path. The focus-detection module (130) is internally provided with first through fourth mirrors (131, 132, 133, 134), a field lens (135) provided between the second and third mirrors and secondary image forming lenses (137) provided between the third and fourth mirrors, whereby two secondary images are formed on the CCD image sensing device (111). The two secondary images are used for rangefinding or focusing.

1. An apparatus comprising:a light reception device receiving light from an object and generating light reception signals thereof; a phase difference determination device determining a phase difference between two light reception signals, generated by said light reception device, respectively corresponding to two light rays in different directions emitted from a part of the object; and a display device selecting one reception signal of the two light reception signals to display an image of the object on the basis of the selected one reception signal.
