Position detecting device, comprising a photo detection element array having n segments and a parallel arithmetic processing portion that is arranged to identify the segment having maximum intensity by comparing the output values (OV) from the segments of the photo detection element array. The parallel arithmetic processing portion comprises at least one comparing stage that is arranged to successively select/deselect the segments, until the segment having maximum intensity is selected, the first stage receiving the output values OV from respective photo detection element segments as input segments (IS) and any additional stage receiving the output values OV from the preceding stage as input segments IS. There is also provided a rangefinder comprising the position detecting device. |
