A distance measuring device is provided with a plurality of comparators which are respectively connected to a plurality of light receiving elements for receiving light reflected from a subject. The plurality of comparators detect the levels of output signals of the light receiving elements. The comparators are supplied with reference voltages to be used for comparison with the output signals, the reference voltages being set different for each comparator according to the distance from whic the respective light receiving element receives light.
A distance measuring device, comprising: a discharge tube for projecting flash light for distance measurement onto a subject; at least one photosensor for receiving a part of flash light projected by said discharge tube and reflected from the subject and generating an output signal indicative of a subject distance; storage means for storing said output signal and generating distance measuring data therefrom; and control means for permitting said output signal to be sent to said storage means during a first preselected time period commencing at the end of...
