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 automatic focus detecting apparatus in which a focal point position corresponding to a change in position of an object after the elapse of a predetermined time is foreseen and calculated on the basis of the result of a past focal point adjustment. In accordance with the aperture value and lens characteristic at the time of photographing, a selection is made with respect to whether the calculation is executed in a normal mode to calculate the focal point position on the basis of only the result of the detection of the focal point at the present time independently of the result of the past focal point adjustment, or the calculation is executed in the foreseeing mode. Upon photographing, if there is no need to execute the foreseeing calculation, the focal point position is calculated in the normal mode.

摘要： A camera including an imaging optical system and a focus detecting circuit for repeatedly performing a focus detection operation and outputting a focus signal representing the focusing state of the optical system at the time of each focus detection operation. A calculation circuit predicts, on the basis of previous and latest focus signals, the focusing state of the optical system a predetermined period of time after the detection of the latest focus signal. The predetermined period of time includes a shutter release time-lag. A driving circuit drives the optical system by an amount corresponding to the focusing state calculated by the calculation circuit. A releasing circuit begins a film exposure in response to the operation of a shutter release member. A release timing control circuit controls the releasing circuit so that it does not operate until a point of time which is earlier, by an amount equal to the release time-lag, than the predicted time.

摘要： An automatic focusing device for driving a lens to the in-focus position by a motor, by driving the motor at a high speed when the lens is distanced from the in-focus position by a large amount, or at a low speed when the lens is distance from the in-focus position by a small amount. Even when the lens is distanced from the in-focus position by a large amount, the high-speed drive is not conducted if the motor has to be switched to the low speed in the course of acceleration to the high speed, in order to prevent strong shock to the user, encountered in case of such sudden change to the low speed drive.
