A vibration correction system for a camera using a correcting lens driven by a reduction gear train attached to a motor. Image deflection, originating from vibration and the like of the camera, is prevented by shifting the correcting lens. A movement detector, to detect the amount of movement of the correcting lens, is arranged near the drive shaft of the motor or near the first couple of gears of the reduction gear train. After the correcting lens has been driven, the connecting lens is reset to a predetermined standard position, based on the output of the movement detector. By placing the movement detector on or near the drive shaft, a high resolving power is obtained. Accordingly, the correcting lens can be shifted with fine precise movements, and accurate correction of image deflection becomes possible.

Vibration correction system for a camera

A camera, such as a video camera or other electrically recordable camera, has scale imprintable capabilities and a method for imprinting a scale onto memory storage media. The camera and method imprints, optically or electrically, a standard scale on memory storage media for the purpose of estimating the size of a subject image. A photographic magnification calculation circuit calculates the photographic magnification based on a subject distance, and a reference scale setting circuit sets a reference scale for the purpose of estimating the size of the subject image on the memory storage media regardless of the magnification during picture taking or print size. An imprinting circuit imprints, optically or electrically, the reference scale onto the memory storage media in accordance with the reference scale setting circuit, and only when needed or wanted. The reference scale can be imprinted in a vertical or horizontal direction in accordance with a mode selection switch. In addition, date, time and other information can also be imprinted onto the memory storage media. Picture taking will not be performed when it is not possible to accurately superimpose the reference scale and warning displays are generated.

The display apparatus according to the present invention includes a display device which has a rotating indicator pointer and which displays information by rotationally driving the indicator pointer, an operating device which is capable of being operated in two manners for rotating the indicator pointer, and a drive control device which rotationally drives the rotating indicator pointer in the same rotational direction, whichever be the one of the two manners in which the operating device is operated.

Rotating indicator pointer type display apparatus

A lens barrel is provided with a lens group that can move against a camera main body, an electrical device that can move with the lens group, and a plurality of flexible printed circuit boards arranged one on top of the other within a space inside the lens barrel, in order to electrically connect the electrical device to an electrical device that is provided outside the lens barrel.

Lens barrel with flexible printed circuit boards

In a lens barrel having at least two joinable cylinders made of plastic, a sink mark is hard to be formed in the two cylinders and the compactness of the lens barrel and low cost are maintained while the construction is not complex and the number of parts is not increased. The leakage of light is prevented even when a joint is shallow.

Lens barrel having at least two cylinders which join to block out

A camera for photography with different angles of view has a finder unit with a conversion lens that retracts into a space produced when a strobe unit pops up, in one embodiment. In another embodiment, the strobe unit is elongated and a finder converter lens moves along a path perpendicular to the length of the strobe unit. In a further embodiment, if a focal length of a zoom lens, corresponding to a desired angle of view, is outside of a range of settable focal lengths, a trimming photographing mode is selected. A zoom finder motor is provided separately from a zoom lens motor. In another embodiment, forward rotation of a single motor drives a finder converting lens, and reverse rotation of the motor drives an illumination angle altering member of a strobe unit. Spot flash operation of the strobe unit may be selected.

Multi-motor camera for normal and trimming photography having variable

A lens barrel including a fixed drum, a rotary drum rotatably fitted in the fixed drum and a lens drum, disposed in the rotary drum, for accommodating lens. The lens drum is movable in the optical-axis direction of the lens with a rotation of the rotary drum. The lens barrel has an adjusting drum disposed in a subject-side position between the fixed drum and the rotary drum. The adjusting drum thread-engages with the fixed drum. The adjusting drum is, when rotated, moved in the optical-axis direction. With this movement, the rotary drum and the lens drum also move in the optical-axis direction, thus adjusting a relative position of the rotary drum with respect to the fixed drum.

Lens barrel with improved drum arrangement

A camera operation directing device includes an eye-gaze direction detection device for detecting a direction of an eye-gaze of an observer who is looking into a finder, in a predetermined eye-gaze operation area within the finder and for outputting an eye-gaze operation signal, and a photographic operation direction device for directing the photographic operation, including at least starting of a photo-taking operation, in accordance with the eye-gaze operation signal from the eye-gaze direction detection device.
