摘要： An auto-focus arithmetic device suitable for use in a photographic camera is provided. The device includes a photographic lens which is movable along a predetermined optical axis and a CCD for detecting light coming from a subject of interest through the lens. An arithmetic unit for determining the direction and amount of movement of the lens with respect to the subject of interest based on a detection signal from the CCD is provided. The arithmetic unit includes an integer portion calculating sub-unit for calculating an integer portion of the detection signal and a fractional portion calculating sub-unit for calculating a fractional portion of the detection signal. The fractional portion calculating sub-unit remains deactivated as long as the detected amount of discrepancy from the in-focus condition is larger than a predetermined level; however, it is activated when the detected amount of discrepancy becomes equal to or less than the predetermined level. In this manner, in accordance with the present invention, the integer and fractional portion calculating sub-units are used alternately.

摘要： A position detecting apparatus electrically detects the present position of a moving body reciprocated within a movable region. The apparatus comprises a resistance section continuously disposed by a predetermined length along the reciprocating direction within a detecting region corresponding to the movable region on a substrate composed of an insulator. A plurality of region discriminating patterns are formed by combining a conductive section discontinuously disposed by a predetermined length along the reciprocating direction within the detecting region on the substrate, and an insulating section having no conductor. An electric brush is provided which is connected to the moving body and reciprocated within the detecting region in a state in which the brush slidably contacts the resistance section and the plurality of region discriminating pattern section. A first position detector detects the position of the moving body based on a resistance value corresponding to the position of the brush when the brush is located on the resistance section. A second position detector detects the position of the moving body by detecting a predetermined kind of combination of the conductive section and the insulating section when the brush is located on the region discriminating pattern sections; both the resistance section and the region discriminating pattern sections are disposed on the substrate. Another position detecting apparatus may be used by electrically detecting the present position of the moving body reciprocated within the movable region.
