摘要： Focus detecting apparatus detecting focus to a plurality of areas has (1) a first auto-focusing mode in which, regardless of an in-focus or out-of-focus state, an auto-focusing operation (including focus detection and driving of an optical system) are repeatedly performed, and (2) a second auto-focusing mode in which the auto-focusing operation is performed until an in-focus state is obtained and the auto-focusing operation is terminated after the in-focus state is detected. A sensor unit is provided for receiving light beams from a plurality of different areas in a photographic scene. A focus processing circuit is provided for, in the first auto-focusing mode, causing the auto-focusing operation to be performed on the basis of an output of a sensor unit representing a particular area of the plurality of areas as long as the output of said sensor unit which represents the particular area is appropriate. In the second auto-focusing mode, the processing circuit selects as a result of the focus detection operation a signal representing a particular focusing state among the focus state signals of each area obtained by the focus detection operation performed on outputs of sensor units corresponding to each area of the photographic scene.

摘要： This invention relates to an automatic focusing device, particular capable of foreseeing the position of an object after a predetermined future time based on the results of a plurality of past focusing operations, thus enabling the focusing to the object. An automatic focusing device is provided which executes calculations for the abovementioned foreseeing after the execution of a predetermined number of focusing operations. However, if a focused state is identified in a focusing operation in the course of the execution of the predetermined number of focusing operations, the device is adapted to disregard the first-mentioned focusing operation as if it had not been conducted and to exclude the first-mentioned focusing operation from the counting of the predetermined number of focusing operations.

摘要： A camera having an automatic focusing device, capable of automatically driving a lens to a shooting lens position where it can simultaneously focus different objects on different positions. The camera has a focus detection circuit capable of detecting focusing positions where the lens is focused on the respective objects. When one of the focusing positions is beyond the limit of drive of the lens, the driving to the shooting lens position is judged to be impossible and the control for driving the lens to the shooting lens position is prohibited.
