Abstract:
A distance-measuring device for individually measuring a plurality of distance-values corresponding to a respective plurality of distance-measured regions, the plurality of distance-measured regions constituting all distance-measurable regions of the distance-measuring device, the distance-measuring device comprising:a selection circuit for selecting at least one first measured distance-value from the plurality of distance-values, wherein the selection is effected such that in the case that more than one of the plurality of distance-values have been determined to be greater than or equal to a predetermined distance-value, the distance-values that have been determined to be greater than or equal to the predetermined distance-value are excluded, and other distance-values of the plurality of distance-values that have not been determined to be greater than or equal to the predetermined distance-value are not excluded; and a computation circuit for computing an auto-focusing data value in accordance with the at least one first measured distance-value selected by said selection circuit.
