摘要： A focus condition detecting device which generated first and second light intensity distribution signals representing light intensity distributions on first and second arrays arranged to receive lights having passed through different areas of the exit pupil of an objective lens is arranged so as to divide the first light intensity distribution signal into a plurality of blocks. Each of the portions of the first light intensity distribution signal belonging to the respective blocks is shifted relative to the second light intensity distribution signal by sequentially changing an amount of shift, so that correlations therebetween are calculated for finding the amount of shift providing the highest correlation. In accordance with the amount of shift found to provide the highest correlation through the correlation calculation with use of the portion of the first light intensity distribution signal belonging to one of the blocks, the shift range for the succeeding correlation calculation with use of the portion of the first light intensity distribution signal belonging to another one of the blocks is restricted to shorten the period of time required for the succeeding correlation calculation.

摘要： A focus detecting device for a camera is disclosed which employs a CCD for producing an image signal carrying focus information. A monitoring circuit has a charge storing circuit for storing the charge generated from a light receiving element, so that the monitoring circuit monitors the amount of light received from the target object to be photographed and produces a charge signal representing the monitored amount. A reference signal generator is provided for producing a reference signal. Since the reference signal generator is defined by the same circuitry as the charge storing circuit, undesirable fluctuation in the charge signal will also be seen in the reference signal. Since undesirable fluctuation in both signals can be counterbalanced with each other, the comparison between the charge signal and the reference signal can be done with high accuracy.

摘要： A camera with an automatic focusing device has an objective lens mounted on a camera. An image formed by the objective lens is divided into a plurality of zones. In each zone, a brightness distribution is obtained so as to detect a rough focusing condition in each zone, thereby producing a plurality of rough focusing condition data. Based on the result of the rough focusing condition data, one zone is selected. Furthermore, a precise focusing condition is detected in the selected zone based on the light contained in the selected zone, so as produce a precise focusing condition data. Based on the precise focusing condition data obtained from the selected zone, the objective lens is driven to an infocus condition.
