Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera device having a pair of image pickup lenses.

[0002]

2. Description of the Related Art By using a video camera, it is possible to capture still images as well as moving images. However, the resolution of the video camera is lower than that of the photo camera,
Often they want to use a photo camera (film camera) with a video camera. Therefore, it is conceivable that the video camera and the photo camera are integrally formed so that the video camera unit captures a moving image while the photo camera unit captures a still image.

In this case, it is necessary to dispose two image pickup lenses of a video camera unit and a photo camera unit in the integrated camera device.

[0004]

By the way, when the image pickup lens is for zooming, a lens mount (lens projecting portion) may be provided and the image pickup lens may be arranged at that portion due to the design of the camera device. When two image pickup lenses are provided as described above, for example, only the image pickup lens of the video camera unit may be used for zooming. In this case, if the image pickup lens of the photo camera unit is arranged close to the lens protrusion of the video camera unit, the lens protrusion is positioned within the angle of view of the image pickup lens of the photo camera unit. There is a risk of imaging the part.

Therefore, the present invention provides a camera device capable of properly capturing an image regardless of which of the pair of imaging lenses is used.

[0006]

According to the present invention, when a pair of image pickup lenses are arranged on the same surface side and a lens protrusion for arranging one of the pair of image pickup lenses is provided,
The other imaging lens is arranged so that the lens protrusion is not located within the angle of view of the other imaging lens.

[0007]

The distance between the lens protrusion 4 on which the one image pickup lens 2 is arranged and the other image pickup lens 3 is designed so that the lens protrusion 4 is not located within the angle of view θ of the other image pickup lens 3. Therefore, even when the image is picked up by the other image pickup lens 3, there is no problem that the lens protrusion 4 is picked up, and proper image pickup can be performed.
