摘要： In an objective lens assembly for an optical instrument comprising inner and outer tube members with outer and inner engaged helicoidal screws, respectively, the normal trapezoidal-section main ridge of the helicoidal screw of the outer tube member is modified to provide one or more wall surfaces that reflect stray light from the object side of the objective lens assembly to prevent such light from reaching the image side of the assembly. The wall surface or surfaces are provided by one or more sub-ridges or grooves at the top of the trapezoidal-section main ridge. Bottom portions between successive elements of the main ridge may be angulated to prevent stray light reflected therefrom from reaching the image end of the assembly.

摘要： A camera which releases the shutter based on the wink of a photographer when vibrations are affecting the camera. The camera includes a wink detection device which detects a wink of the photographer and produces a corresponding wink detection output signal, and a vibration detection device which detects vibrations affecting the camera and produces a corresponding vibration detection signal. A control mechanism is responsive to the wink detection output signal and the vibration detection signal to control the release of the shutter. The wink detection device operates by emitting a visible light signal towards the photographer's eye, reflecting the signal off the photographer's eye, and then receiving the reflected signal. A wink of the photographer is detected based on the amount of reflected light received by the light receiving device. The wink detection device includes an LED which emits the signal. The LED can also operate as an indicator in the viewfinder to notify the photographer that the shutter will be released upon a wink. A cover member can be arranged between the camera and the face of the photographer to protect the wink detection device and the photographer's eye from being exposed to dust and particles, thereby preventing unintended blinking or inaccurate detection of a wink.

摘要： Range measuring device for a camera measures the distances to objects respectively present in a central area of the photographing field and in plural areas including those surrounding the central area, then produces an outdoor signal indicating that the photographing is conducted outdoors or an indoor signal indicating that the photographing is conducted indoors, discriminates whether the object in the central area is the main object to be focused from the measured distance of the central area, and, if the distance in the central area is included in a reference distance range, determines the photographing distance based at least on the measured distance of the central area. The reference distance range is selected to be larger when the outdoor signal is produced than the case when the indoor signal is produced.
