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 focus detecting device gathers first image data by a couple of linear arrays of photo diodes in a CCD, which are disposed oppositely with respect to an optical axis of an objective, and second image data by a couple of photo diodes arrayed disposed close to one of the photo diode arrays. A CPU calculates a integer part and fractional part of a displacement of first and second images represented by the first image data, and checks if the calculation results are reliable for focus detection, by using the first and second image data. A counter contained in the CPU counts the number of decisions of unreliable. When a count of counter reaches a preset value and when the latest decision of unreliability is made for the integer part calculation result, a subsequent lens drive is prohibited, and the integration by the CCD, and the integer part calculation are repeated, while presenting a display of "Unmeasurable". Further, an additional reliability check is made of the result of the latest integer part calculation. If the additional reliability check shows a satisfactory reliability, the CPU goes out of the repetitive operation of the integration and the integer part calculation, and removes the prohibition of the lens drive.
