摘要： In the distance measuring apparatus, it is determined whether or not a pair of AF data obtained by a pair of employed sensors indicate a first predetermined necessary contrast, and a correlation value calculation is performed only when the contrast is detected. Then, it is determined whether or not the AF data in a pair of window ranges where the highest correlation is obtained in a correlation value calculation indicate a second predetermined necessary contrast. Only when it is determined that there is the contrast, the subsequent process such as a calculation of the distance from a distance measurement object is performed. Thus, an unnecessary correlation value calculation can be possibly omitted at a low contrast level. Furthermore, erroneous measurement of distance can be avoided.

摘要： In a rangefinder, if sensor data initially received by a sensor data storage part from an A/D converter includes data with low contrast, the sensor data storage part receives the sensor data at least one additional time, adds additionally received sensor data to the initially received sensor data, and stores their sum. In accordance with the sum of sensor data stored in the sensor data storage part, a correlation calculation and a rangefinding calculation are carried out, which enables rangefinding with respect to an object having low contrast. Also, the time required for A/D-converting the sensor data again and adding the resulting data to those initially obtained is much shorter than the integration time required for integrating output signals of a pair of line sensors a second time for a region with low luminance and low contrast.

摘要： The sensor sensitivity and the method of setting the peak selected area of the AF sensor are changed according to the luminance level of the distance measurement object. The distance measuring apparatus uses a passive AF sensor to determine the distance of a distance measuring object by sensor data obtained from the AF sensor, wherein: if the distance measurement object has high luminance, the sensor sensitivity is set at low sensitivity, the distance measurement area is divided into three areas, and sensor data is acquired for each area as a peak selected area of the AF sensor; if the distance measurement object has moderate luminance, the sensor sensitivity is set at low sensitivity, and sensor data is acquired with the entire area of the distance measurement area being the peak selected area of the AF sensor; and if the distance measurement object has low luminance, the sensor sensitivity is set at high sensitivity, and sensor data is acquired with the entire area of the distance measurement area being the peak selected area, whereby proper sensor data is acquired to carry out distance measurement suitably and reliably.

摘要： A correlation value calculation is performed by using AF data arranged at predetermined intervals in the AF data in a pair of window ranges, so that a frequency of calculation can be reduced. On the other hand, a correlation value calculation is performed by using all the AF data in the pair of window ranges only in predetermined ranges before and after the shift amount of the pair of window ranges when the highest correlation value in the correlation values is obtained, thereby suppressing a reduction in measurement precision. For example, in a pair of the AF data obtained from a pair of window ranges, the correlation value calculation is performed by using every third piece of the AF data. Then, the correlation value calculation (normal calculation) is performed by using all the AF data in the pair of window ranges in predetermined ranges (range for re-performing the calculation) before and after the shift amount of the pair of window ranges when the highest correlation value is obtained in the correlation values obtained by the former correlation value calculation.

摘要： Correlation value calculation is carried out while a pair of window ranges being shifted using uncorrected AF data, and a pair of window ranges providing the highest correlation value is determined. Then, the difference between the smallest values in the respective window ranges is evaluated. If it is determined that the distance is large, the AF data is corrected so that the smallest values in the respective window ranges are consistent with each other, and the corrected AF data is used to carry out correlation value recalculation. Then, if the highest correlation value after correction is smaller than the highest correlation value before correction, the result of correlation value calculation after correction is employed.
