Abstract
In each of left and right lens devices used in the three-dimensional camera, an antivibration lens group for preventing image blur caused by vibrations is disposed in an image-pickup optical system. A movement instructing device which adjusts, by manual operation, a reference position at which the vibration lens group is fixedly held when antivibration control is stopped is provided in an operation unit about the vibration control. An improper feeling of a three-dimensional image caused by optical-axis misalignment can be reduced by adjusting the reference position of the antivibration lens group by the movement instructing device.
Claims4
A three-dimensional-camera lens system comprising:
- a plurality of image-pickup optical systems respectively forming images of an object on image-pickup planes of a plurality of image-pickup devices of a three-dimensional camera for picking up a three-dimensional image;
- an antivibration optical system disposed in the image-pickup optical system, the antivibration optical system changing an image formation position of the image formed by the image-pickup optical system in a plane of the image-pickup plane by changing a state of the antivibration optical system in the image-pickup optical system;
- a driving device driving the antivibration optical system to change the state of the antivibration optical system;
- a vibration detecting device detecting a vibration of the image-pickup optical system;
- an antivibration control device changing the state of the antivibration optical system by the driving device based on the vibration detected by the vibration detecting device and changing the image formation position of the image formed by the optical system with respect to the image-pickup plane so as to carry out antivibration control of canceling out image blur caused by the vibration;
- an inputting device inputting an instruction about driving of the antivibration optical system disposed in each of the plurality of image-pickup optical systems;
- and
- an optical-axis adjustment control device driving the antivibration optical system for adjusting an optical axis of the image-pickup optical system by the driving device in accordance with the instruction input by the inputting device when the antivibration control of the antivibration control device is stopped.
