摘要： In addition to a focus detecting sensor for phase difference detection, a camera is provided with a light source or a generator for emitting light or ultrasonic waves, and a light receiver or a receiver for receiving the light or the ultrasonic waves reflected from the object. The distance to the object is detected from the intensity of the reflected light or ultrasonic waves and the focusing lens is set at a position close to the in-focus position. Then, the driving range of the focusing lens is limited in accordance with the detected distance, and from the set focusing lens position, focusing by the phase difference detection method is performed within the limited driving range.

摘要： A distance measuring apparatus includes distance measuring units of the active and passive methods, and a distance-value selecting circuit for selecting and outputting one of distance measurement results obtained from these distance measuring units. When a self-timer mode is set, distance measurement of the active method is inhibited, and distance measurement is executed by only the passive method. When the power supply voltage is lower than a predetermined voltage value at which distance measurement can be properly executed by the active method, distance measurement by the active method is inhibited, and distance measurement is executed by only the passive method. Therefore, erroneous distance measurement can be prevented, and distance measurement having high reliability can be performed.

摘要： A focus detection device includes a pair of photoelectric converting element arrays that output a pair of signal strings and a focus detection optical system, including a photo lens, that conducts a pair of light rays from a subject to the pair of photoelectric converting element arrays. A filter extracts a pair of signal strings having a predetermined frequency component from the pair of signal strings outputted by the photoelectric converting element arrays. A calculation range setting device sets a calculation range of signals of the pair of extracted signal strings, and a focus detection calculating device calculates a focus adjustment condition for the photo lens based on the signals of the pair of extracted signal strings in the calculation range. A contrast calculation device calculates the contrasts in areas outside the calculation range based on the signals of the pair of extracted signal strings excluded from the calculation range, wherein the operation of the focus detection calculating device is dependent upon the calculated contrasts. When the calculated contrast exceeds a predetermined value, focus detection calculations based on a pair of signal strings with lower frequency components are not carried out, or else the shift range for correlation calculations is narrowed, or else the threshold values for reliability determination are changed and the reliability determination standard is made to be more restrictive, or else the focus detection calculation range is narrowed.
摘要翻译：焦点检测装置包括一对光电转换元件阵列，其输出一对信号串，以及包括光学透镜的焦点检测光学系统，其将来自被摄体的一对光线传导到该对光电转换元件阵列。滤波器从由光电转换元件阵列输出的一对信号串提取具有预定频率分量的一对信号串。计算范围设定装置设定一对提取信号串的信号的计算范围，焦点检测计算装置根据计算范围内的提取出的一对信号串的信号，计算出光学透镜的聚焦调整条件。对比度计算装置根据从计算范围排除的一对提取信号串的信号，计算出计算范围外的区域的对比度，其中焦点检测计算装置的操作取决于所计算的对比度。当计算出的对比度超过预定值时，不执行基于具有较低频率分量的一对信号串的焦点检测计算，否则用于相关计算的移位范围变窄，或者用于可靠性确定的阈值改变，使可靠性确定标准更具限制性，或者聚焦检测计算范围变窄。
