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 focussing apparatus having a plurality of sensors of the signal accumulation type includes a plurality of accumulation-type sensor sections for respectively receiving light from different object areas. Each sensor section produces, in response to a first signal, a signal which is variable in accordance with an amount of light received thereby. The signal produced by each sensor section is independently output to a signal processing circuit through an output terminal portion in response to a second signal. A control circuit supplies the first signal to each sensor section substantially at the same time, and monitors a signal producing state of each sensor section independently. The control circuit then supplies the second signal to the sensor section which reaches a predetermined monitoring state.

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： An apparatus for detecting the focus state of an optical system has optical apparatus for forming first and second light distributions of an object. The relative positional relationship of the light distributions varies in accordance with the focus state of the optical system. A light receiving device has first and second ranges, each having a plurality of picture elements. The first and second ranges respectively receive the first and second light distributions. Operation circuitry manipulates the output signals from the first and second ranges by relatively mathematically moving them to calculate a value representing the focus state of the optical system. The operation circuitry selectively executes a first operation in which the number of signals corresponding to each other is varied, and a second operation in which the number of signals corresponding to each other is kept constant.
