    摘要: A camera lens actuation apparatus for driving motion of a camera lens supported on a support structure by a suspension system. The apparatus incorporates a subassembly comprising SMA wire connected to at least one mounting member which is mounted to the support structure. At least one pair of lengths of SMA wire are held in tension between the camera lens element and the support structure at respective acute angles to the optical axis applying a tensional force having a component along the optical axis. The lengths of SMA wire in the pair are held at angle as viewed along the optical axis. There may be plural pairs with a balanced arrangement in which the forces generated have no net component perpendicular to the optical axis and generate no net torque around any axis perpendicular to the optical axis. A control circuit controls heating of the SMA wire in response to a measure of its resistance.

    摘要: A camera assembly (12) may include an autofocus assembly (14) that selectively imparts a first displacement between a lens assembly (16) and an imaging sensor (18) and a second displacement between the lens assembly and the imaging sensor. The autofocus assembly includes at least one positioner (46) and an actuator (58). The actuator is configured to move the positioner between a first position in which the positioner contacts a first surface that is in a first plane corresponding to the first displacement and second position in which the positioner contacts a second surface that is in a second plane corresponding to the second displacement. The first and second planes may be offset so that a distance between the first displacement and the second displacement directly corresponds to a distance between the first and second planes.

    摘要: The present invention relates to an image projection apparatus, a projection image pattern, a laser drive apparatus and a camera apparatus fit for use with an electronic still camera for example. In the present invention, when a microcpmputer 8 detects that a shutter release 9 is depressed, a focusing lens 3 is controlled so that a contrast signal obtained when a luminance signal from a camera signal processing circuit 6 is supplied to an auto focusing detection circuit 7 may become maximum. A control signal from the microcomputer 8 is supplied to a laser driver 13, so that a laser diode 14 is driven to generate light of laser beams only while this control signal is supplied to the laser driver. The light of laser beams thus generated is further condensed into light of parallel laser beams by a condenser 15. These parallel laser beams are applied to a hologram plate 16 and thereby diffracted. The laser beams thus diffracted are caused to interfere with each other, whereby a hologram reproduced image 17 is reproduced. This makes it possible to project a hologram reproduced image with sufficient contrast onto an object by small power consumption. Therefore, satisfactory focusing can be made in an auto focus mode of the contrast detection system or in a manual focus mode. At the same time, this apparatus can really be incorporated, for example, into a small electronic still camera with ease.

The servo module (12) is detachably mounted to a lens device (10) body and contains a CPU (36), and is provided with A/D converters (30, 32) for A/D converting an analog control signal and a lens position signal for focus and zoom from the lens device (10) body, and a digital signal communications interface (34). A parameter value of the braking characteristic can be changed by operating a switch unit (50). Memory (48) stores an initial set value of the braking characteristic, and the initial set value can be restored as necessary. In addition, an indicator (lens status display portion) (14) mounted in the lens device (10) body is used as a unit for checking the parameter value of the braking characteristic.
