Abstract: An image processing apparatus, including circuitry configured to cause an aperture diaphragm to move from a first diaphragm position to a second diaphragm position within a first exposure period. The circuitry is further configured to cause the aperture diaphragm to then move from the second diaphragm position to the first diaphragm position within the first exposure period or a second exposure period. The first and second exposure periods are used to capture different images.

Abstract: An interchangeable camera lens includes a main barrel for holding a diaphragm and optical elements, wherein the optical elements define an optical axis (A), a diaphragm rotating ring, rotatable by way of a rotational movement about the optical axis (A), for setting the diaphragm to different f-number values, and a click-stop device. The click-stop device interacts with the diaphragm rotating ring in such a way that the click-stop device is effective in an active work position and the diaphragm rotating ring is therefore rotatable in a stepped manner. The click-stop device is ineffective in an inactive work position and the diaphragm rotating ring is therefore continuously rotatable, wherein the click-stop device comprises a click-stop element seated on a pressure element. The click-stop element is pressable into click-stop grooves by the pressure of the pressure element to enable a step-wise rotation of the diaphragm rotating ring in the active work position. Means are provided for selectively activating and deactivating the click-stop device, wherein the means comprise a movement element which is arranged between the pressure element and the click-stop element and a switching element is assigned to the movement element to fix the movement element in such a detachable manner that the click-stop element is pressable into a click-stop groove by the pressure element in the active work position and not pressable into the click-stop groove by the pressure element in the passive work position.

Abstract: A digital camera is provided with a photographing lens having a aperture mechanism, an imaging section, including an image sensor for capturing a subject image via the photographing lens, a display section capable of displaying image information, an aperture drive section for driving the aperture mechanism to a specified position in response to manual operation of a preview instruction member, and a control section for causing execution of an exposure operation for a specified period in the imaging section, and causing display of a moving image on the display section based on image data acquired by the exposure operation. The control section stops the moving image display during drive of the aperture mechanism by the aperture drive mechanism, to thereby prevent unnatural variation in brightness of an image in live view display when a preview operation is carried out.

Abstract: A shutter release device for an autofocusing camera has a release member movable by manual operation from an initial position to a first position, and from the first position to a second position. A first release device connected to the release member releases a focus adjustment mechanism upon movement of the release member to the first position. The focus adjustment mechanism has a first lock device for holding a shutter operating mechanism in a first locked condition, and releases the shutter operating mechanism upon release of the focus adjustment mechanism. A second lock device, controlled by an electromagnet, holds the shutter operating mechanism in a second locked condition, and a second release device actuated by movement of the release member to the second position causes the electromagnet to release the second lock device and thereupon the shutter operating mechanism. Thus, a simple shutter release device is provided for the autofocusing and shutter operating functions using a single control electromagnet.

Abstract: An abutment pin is provided for defining the fully open position of the aperture release member on an interchangeable lens. The aperture drive member on the camera is biased toward the abutment pin so that the rest position of the drive member will always correspond to a fully open aperture regardless of lens misalignment. The aperture stop down is then controlled by measuring the movement of the drive member from its rest, or start, position.

Abstract: A camera has a camera body, an interchangeable lens engageable with the camera body, and a rotatable diaphragm setting ring on the lens. A first mounting member on the camera body interlocks with a second mounting member on the lens to engage the lens with the camera body. A hole is formed in the second mounting member adjacent to the first mounting member and a slideable lock pin is disposed in the hole. The ring is rotatable between an automatic diaphragm control position and a range of diaphragm preset positions. Responsive to the diaphragm setting ring, the pin is retracted to a position approximately flush with the surface of the second mounting member when the diaphragm setting ring is within the range of diaphragm preset positions and the lock pin is extended outwardly from the surface of the second mounting member to the region occupied by the first mounting member when the diaphragm setting ring is at the automatic diaphragm control position. In camera bodies with automatic diaphragm control, the first mounting member has a recess aligned with the hole in the second mounting member to receive the pin in its extended position. In camera bodies without automatic diaphragm control, the first mounting member has a surface abutting the hole in the second mounting member to prevent the lock pin from extending therefrom, thereby blocking rotation of the diaphragm setting ring into the automatic diaphragm control position.

Abstract: A diaphragm for photographic cameras and the like, of the type where the diaphragm closes down rapidly from a wide open aperture for viewing to a preselected smaller aperture for picture taking, immediately prior to the actual exposure. The usual slotted ring connected to the diaphragm leaves or blades is stopped in its running down movement by contact with an interception ring whose position is determined by a diaphragm presetting member, the contact between the interception ring and the presetting member including a resiliently displaceable ball. As the slotted ring runs down, it is stopped by impact with the interception ring, which absorbs some of the kinetic energy of the slotted ring, and the resiliently mounted ball connection with the position determining lever (stationary at this time) allows the interception ring to move slightly further beyond the position to which it has been preset, thus bringing the moving parts to a smooth cushioned stop and effectively damping any rebound or bounce which might otherwise occur as a result of quickly stopping the fast running down movement of the diaphragm.

Abstract: In an objective lens removably mountable with respect to a camera housing and having a diaphragm member forming an aperture and diaphragm driving means displaceable to stop down the diaphragm member in a range over which the area of the aperture is from maximum to minimum, the housing having a metering circuit for measuring the light transmitted through the lens when the aperture is maximum, diaphragm correcting means are provided on at least one of the diaphragm driving means and the diaphragm member to impart a correction of the stop down step number corresponding to the difference between a theoretical metering output calculated from the open F-value of the lens and the brightness of an object and the actual metering output of the metering circuit, to the relation between the variation in area of the aperture and the displacement of the diaphragm driving means.
