Abstract:
There is provided an intermediate adapter having a camera shake correction function, in which an exchange head provided with an image taking optical system and an imaging device is applicable to a camera system, and a camera system having the intermediate adapter. The exchange head is mounted on the intermediate adapter having a head driving section, and the exchange head mounted on the intermediate adapter is mounted on a camera main frame. The head driving section drives the exchange head in accordance with a detection signal detected by a camera shake detection section of the intermediate adapter.
Abstract:
A lens barrel has its length which is reduced by dispensing with guide rods or a travel mechanism long extending from a base which fixes an image pickup device. The optical axes of multiple lens groups can be easily aligned. An image taking apparatus has its body which has the lens barrel incorporated into it. A second lens group, third lens group and, via the travel mechanism, a fourth lens group are supported by a straight-ahead key ring, and the straight-ahead key ring also supports a front tube holding the first lens group. A zoom motor and a focus motor are also supported by the straight-ahead key ring.
Abstract:
A main frame adapter is detachably mounted, instead of a camera head, on a camera main frame from which the camera head is separated. The camera head comprises an image taking optical system and an imaging device. The camera main frame is adapted to receive an image signal from the camera head that is detachably mounted on the camera main frame. A head adapter that is detachably mounted, instead of the camera main frame, on the camera head separated from the camera main frame. Both the adapters have each the radio communication section.
Abstract:
A lens unit has a photographing lens, and is secured removably to a camera main body. An accessory conversion lens device is settable on the lens unit. The lens unit includes a reception unit for receiving accessory device data from the conversion lens device. A determiner checks propriety of the conversion lens device according to accessory device data received by the reception unit, and produces checking information. A transmission unit transmits the checking information to the main body. Specifically, the lens unit has an image pickup element. Also, the conversion lens device includes an RFID tag for storing the accessory device data. The reception unit includes an RFID tag reader for wireless reception. Also, the main body includes an LCD panel to display for outputting alarm information. A main body controller drives the LCD panel if the checking information represents lack of the propriety.
Abstract:
A camera with a removable imaging lens unit is a small and reliable camera which can prevent electrostatic discharge from causing breakdown or malfunctions. Electrical contact points on a camera body are covered and protected by a mount barrier. When mounting the imaging lens unit on the camera body, a push head is placed in contact with the mount barrier and pushes the mount barrier. After the push head pushes down the mount barrier against the urging force of the spring, electrical contact points on the lens unit are connected with the electrical contact points on the camera body.
Abstract:
A piezoelectric actuator having a frame portion includes a drive shaft for frictional engagement with an engageable barrel arm of a lens unit. First and second piezoelectric elements are supported on the frame portion, and provided with first and second ends of respectively the drive shaft. A drive pulse generator supplies the piezoelectric elements with a drive signal to expand or contract the piezoelectric elements, and moves the engageable barrel arm in an axial direction by an alternately repeating sequence of shifting the drive shaft at low and high speeds in the axial direction. In the shifting at the high speed, the piezoelectric elements shift the drive shaft in a backward direction quickly, to move the drive shaft in the backward direction relative to the engageable barrel arm being stationary with inertial force.
Abstract:
A lens barrel has its collapsed length which can be further decreased and its extended length which can be further increased. A photographic apparatus incorporates the lens barrel into its body. A lens barrel is equipped with a first gear which is rotatably supported by a straight-ahead key ring and rotates being driven by rotation of a middle tube and a second gear which receives driving force from the first gear and retracts a second lens group to a predetermined retracted position off the optical axis of a zoom lens during collapse and advances the second lens group onto the optical axis during extension. The second gear lacks teeth in that part which faces the first gear when the second lens group is at the retracted position during collapse. Consequently, the first gear runs idle while facing that part thereby holding the second lens group at the retracted position.
