Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a multi-view imaging device.

[Prior Art] In the case of a conventional multi-lens imaging device as shown in FIG. 3, the optical systems 1 and 2 and the imaging units 3 and 4 are arranged so as to form a constant convergence angle. It had been. In terms of human vision, the convergence angle is the angle formed by the optical axes (line of sight) of the left and right eyeballs.

Humans determine their viewpoint by changing the convergence angle,
Perceiving objects. Therefore, it is desirable that video data used in a device such as a stereo television that can input separate images to the left and right eyeballs be photographed with a certain degree of convergence angle.

[Problems to be Solved by the Invention] However, in the conventional technology, since the light angle is fixed, the effect can only be exhibited within a certain range. Another problem is that it is very difficult for the photographer to readjust the convergence angle depending on the distance of the object to be photographed.

Therefore, the present invention is intended to solve these problems.
The purpose is to provide a multi-lens imaging device that can automatically adjust the convergence angle depending on the distance of the object to be photographed.

[Means for Solving the Problems] A multi-lens imaging device of the present invention includes at least two imaging means, a focus adjustment means for adjusting the focal length of the imaging means, and focus information from the focus adjustment means. a convergence angle determining means for calculating a required convergence angle based on the received convergence angle, and a driving means for receiving a signal from the convergence angle determining means and moving the imaging means to realize a desired convergence angle. It is characterized by

[Example] The present invention will be explained in detail below based on the drawings.

FIG. 1 shows an embodiment of the multi-lens imaging device of the present invention.

The photographic objects imaged by optical system 1.2 are each CCD
The image is input to an imaging section 3.4 composed of photoelectric conversion elements such as. The imaging unit 3.4 converts the object into a video signal 100.10.
1, and outputs high frequency components 102 and 103 of the video signal as signals for automatic focus adjustment.

The automatic focus adjustment unit 5 determines whether or not the focus is on based on the signals 102 and 103, and outputs a drive control signal to the optical system drive unit 6.7 according to the result to drive the optical system 1.
2 to perform the focus adjustment operation. Further, the focal point information at that time is output to the convergence angle determining section 8. Radiation angle judgment unit 8
calculates an appropriate convergence angle based on the focus information from the automatic focus adjustment section 5, and rotates the unit 11.12 including the optical system and the imaging section via the unit drive section 9.10 to adjust the necessary convergence. Realize the corner.

FIG. 2 shows another embodiment of the invention.

The object to be photographed is reflected by a rotatable reflecting mirror 13.14 and is input to an imaging section 3.4 via an optical system 1.2. Imaging unit 3
．． 4 outputs a video signal 100.101 and an automatic focus adjustment signal 102.103 as in the previous embodiment. The operations of the automatic focus adjustment section 5 and the optical system drive section 6.7 are the same as in the previous embodiment.

The convergence shift angle determination unit 8 determines the necessary convergence angle based on the focus information from the automatic focus adjustment unit 5, and the unit drive unit 9.10
to obtain the desired angle of convergence.

Both of the above two embodiments are cases in which an automatic focus adjustment function is provided, but manual focus adjustment is also possible since focus information is obtained from the focus adjustment mechanism.

[Effects of the Invention] As explained above, according to the present invention, by automatically realizing the convergence angle calculated from the focal length, it is possible to capture a stereoscopic image with a stronger sense of reality. .
