摘要： In representing a depth of field in a camera, the depth of field is displayed on the basis of the magnitude of a field depth feeling Df which corresponds to human feeling. The field depth feeling Df is obtained by proccesing at least one of a depth of field on calculation, an object distance, a lens hypen-focal length, a diameter of permissible circle of confusion, a lens aperture value and a lens focal length.

摘要： A switching device comprising a rubber switch, an operating member displaceable between at least two operative positions and a neutral position, and a cooperating member shiftable between the at least two cooperative positions and neutral position in response to displacement of the operating member. The operating member and the cooperating member are held in their neutral position due to the resilience of the rubber switch, while one contact is brought into engagement with a corresponding conductive element in the rubber switch when the corresponding cooperating member is shifted to one of the cooperative positions in response to the displacement of the operating member against the resilience of the rubber switch.

摘要： A release device for unlocking the back-cover of a camera includes a back-cover lock member urged in a direction to lock the back-cover, an operating lever pivotally disposed along a side of the camera and operable externally of the camera so as to be angularly displaced therefrom and an interlocking plate for interlocking the operating lever with the back-cover lock member. The operating lever is engageable with the interlocking plate after the operating lever is angularly rotated through a predetermined preliminary angle in an opening direction from a position where the operating lever is disposed along the camera body so as to displace the interlocking plate and to correspondingly displace the lock member to thereby unlock the back-cover. The interlocking plate is interlocked with a film rewind shaft so as to move the film rewind shaft in a direction to disengage the shaft from a film cartridge in accordance with the movement of the back-cover lock member to its unlocked position when the operating lever has been rotated beyond the predetermined preliminary angle.
摘要翻译：用于解锁相机的后盖的释放装置包括沿着锁定后盖的方向被推动的后盖锁定构件，沿着照相机的侧面可枢转地设置的操作杆，并且可在照相机的外部操作，以便与其成角度地移位，以及互锁板，用于将操作杆与后盖锁定构件互锁。操作杆在操作杆沿着照相机主体沿着打开方向从预定的预定角度旋转预定的预定角度以使操作杆沿着照相机主体设置，以便使互锁板移位并相应地使锁定构件，从而解锁后盖。互锁板与胶片重绕轴互锁，以便当操作杆具有的位置时，根据后盖锁定构件的移动到其未锁定位置，使胶片倒带轴沿着从轴与胶片暗盒脱离的方向移动旋转超过预定的预备角度。

摘要： A pop-up flash unit 20 for an SLR camera includes an integral auxiliary light emitting device 26 for projecting a predetermined pattern along the camera lens axis to provide sufficient auto-focusing contrast. A triangular prism 60 forms a window in a front wall 16a of the flash unit chamber 16 confronting the condenser lens 25 of the auxiliary light emitting device such that the predetermined pattern projected by the downwardly angled emitting device, when the flash unit is retracted, is bent upwardly to still fall along the camera lens axis.
