    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 processing 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: 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 and sensitivity. The field depth feeling Df is obtained by processing at least one of a calculated depth of field, an object distance, a lens hyper-focal length, a diameter of a permissible circle of confusion, a lens aperture value and a lens focal length.

    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: 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.
