Abstract: An auto focusing device for a camera includes a focus detecting section which detects a focused state of an image taking lens an AF mode setting section sets an AF mode of the camera to either a first AF mode or a second AF mode. An auxiliary light emitting section emits an auxiliary light to the object in association with the focus detecting operation by the focus detecting section if the object has a low luminance. An emission control section limits the number of times that the auxiliary light emitting section emits the auxiliary light to the object to one per a predetermined number of operations by the focus detecting section if the AF mode setting section has set the AF mode to the second AF mode.

Abstract: A shutter abnormality detection apparatus for a camera includes a shutter including leading and trailing curtains which are shutter curtains electrically controlled to run. A curtain run detection unit detects a run state of at least one of the leading and trailing curtains. A curtain run time judgment unit judges a run time of the shutter curtains based on an output from the curtain run detection unit. An abnormality processing unit notifies an abnormality state of the shutter curtains, when it is judged as a result of judgment in the curtain run time judgment unit that the curtain run time is abnormal.

Abstract: In an auto focusing system of the present invention, a light from an object is guided by an optical section to a light receiving section constituted of an imager such as a photoelectric transducer, and the object is imaged as a digital image at the light receiving section. A movable split image prism is arranged between a position immediately before a light receiving surface of the light receiving section in an optical path of the optical section and a position outside the optical path. Then, a deviation amount of a vide signal based on light rays passed through the split image prism is detected by a control section, and focusing of the optical section is carried out based on the deviation amount.

Abstract: A panning shot check unit checks whether a panning shot is succeeded or not on the basis of an output from a focal point detection unit for detecting an in-focus state of a photographing lens to output a focal point detection signal and an output from a blurring detection unit for detecting an amount of blurring acting on the camera. A shutter speed change unit changes a shutter speed to obtain the effect of a panning shot when it is determined by the panning shot check unit that the panning shot is succeeded. A control unit turns on a panning shot success display unit in a finder when it is determined by the panning shot check unit that the panning shot is succeeded so as to inform a photographer that the panning shot is succeeded.

Abstract: In a multiple-point automatic focusing camera of this invention, when a focal point is detected to a focal point detecting region in the center of a shot screen by an AP sensor and a main control circuit, a LED having a narrow light distribution angle is used as a supplemental light source. On the other hand, upon detecting the focal point in a focal point detecting region in the periphery of the shot screen, a stroboscope light source having a wide light distribution angle is used as the supplemental light source. As a result, the focal point can be detected in any focal point detecting region even at the time of a low luminance. At this time, the stroboscope light source may be originally equipped for illumination at the time of photographing. Further, the LED may be of small size having a narrow light distribution angle. Thus, the size of the supplemental light source can be suppressed.
