Abstract: A hand tremor compensating apparatus for a video camera has a bobbin for supporting and protecting a mirror section. The bobbin has a contact portion with a groove provided therein. A barrel is disposed at an outside of the bobbin. The barrel has a boss in which a post is inserted. The bobbin is slidably mounted on the boss. A rotation restraining section employs a magnetic force to restrain the movement of the bobbin. The magnetic force is an attractive force generated between magnets respectively fixed to the bobbin and the post.

Abstract: A mirror mechanism for a continuous-motion cinematograph film projector. A drive shaft is mechanically coupled to the film transport and is coupled through a slipping clutch to drive a cam. A cam follower riding on the cam profile oscillates a compensating mirror. Frame synchronization of the mirror scan is effected by detection of optical synchronizing marks on the film. Release pulses are generated in response to the synchronizing marks to energize a solenoid to release a blocking member which otherwise blocks movement of the cam.

Abstract: Image display from a continuously moving image carrier with the aid of a repeatedly advanced and reset optical compensator is improved by omitting the traditional compensator bias spring and resetting the compensator with electric power pulse doublets. A substantially constant driving torque may be provided for the compensator in proportion to a damping term of the compensator equation of motion. An electric bias may alternatively or additionally be provided for biasing the compensator during image display against the direction of advance motion. Decelerating power may selectively be applied to the compensator to prevent or correct overshooting in the advance direction.

Abstract: Fiducial markings having different relative contrasts are sensed from an information carrier. Different first electric signals corresponding, respectively, to the different relative contrasts are generated in response to the fiducial markings. Sensing signals indicative of the fiducial markings substantially independently of the different relative contrasts are produced by converting the different first electric signals into corresponding second electric signals having at least one common characteristic.

Abstract: Motion picture projection apparatus, for use with filmstrips having aligned images areas and spaced discontinuities such as sprocket perforations or frame lines having fixed spacial relationships to the locations of the image areas on the film, includes a drive mechanism for continuously moving film through an illuminated film gate aperture. The resulting projected images are reflected by a rotatable mirror. An electromagnet clutch is actuable by a free-running multivibrator to interconnect the mirror and the film drive mechanism for rotating the mirror in timed relation to the film movement, thereby maintaining the projected image stationary. A shutter is responsive to the multivibrator output to permit illumination of the film in the gate during mirror movement in one direction and to prevent such illumination of the gate during the return stroke of the mirror. While the free-running time of the multivibrator is a few milliseconds longer than the film frame rate, it is synchronized with the frame rate by a trigger circuit controlled by a film discontinuity sensing device.
