Abstract

PURPOSE:To provide a compact image pickup device capable of projecting multiscreen on a solid-state image pickup element at a low cost. CONSTITUTION:The image pickup device is constructed by a prism 1 which is mirror coated and forming mirror surfaces 1a and 1b on both sides, integrated lens 2 forming two lens 2a and 2b on one base, supporting frame 3, and solid- state image pickup element 4 focusing pictures from the lens 2a and 2b. The objects on both sides are reflected by respective mirror surfaces 1a and 1b of the prism 1 through respective lens 2a and 2b and projected on the left half and right half part of the solid-state image pickup element 4. Thus, the right and left objects can be seen at once through one solid-state image pickup element 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup apparatus for projecting a screen onto a solid-state image pickup element used in a video camera or the like.

[0002]

2. Description of the Related Art In recent years, solid-state image pickup devices have begun to be used in image pickup devices such as video cameras and broadcast cameras. As shown in FIG. 2, the conventional image pickup apparatus has one lens (or optical system) 12 arranged in front of the solid-state image pickup element 11, and one subject image in front of the lens 12 is projected on the solid-state solid-state image pickup element 11. Was there.

As described above, the solid-state image pickup device 11 is used also in the conventional image pickup apparatus, but it has been used to photograph one subject.

[0004]

However, in the image pickup apparatus having the conventional configuration, when trying to see a plurality of subjects at one time, as many image pickup apparatuses as the number of subjects are required. For example, it is desired to see right and left at the same time. At times, two image pickup devices are required, resulting in a double cost and a large size.

The present invention solves the above problems, and an object of the present invention is to provide an imaging device capable of projecting a plurality of subjects on one solid-state imaging device.

[0006]

In order to solve the above-mentioned problems, an image pickup apparatus of the present invention comprises a path changing means such as a prism for taking in a plurality of objects by reflecting or refracting an object image, and the path changing means. It is provided with a plurality of lenses that individually focus a plurality of guided subject images, and one solid-state imaging device on which the images from these lenses are formed.

[0007]

With the above structure, a plurality of subject images can be formed on a single solid-state image pickup device. Therefore, even when seeing a plurality of subjects such as left and right subjects, one image pickup device is sufficient. However, it is possible to provide an imaging device that can be configured in a small shape without cost.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. As shown in FIG. 1, the image pickup device includes a prism 1 as a path changing unit which is mirror-coated and has mirror surfaces 1a and 1b formed on the left and right sides, and a prism 1 provided on one substrate.
Integrated lens 2 in which two lenses 2a and 2b are formed
And a support frame 3 for supporting the prism 1 and the integrated lens 2 and one solid-state image sensor 4 on which images from the lenses 2a and 2b are formed.

According to the above arrangement, the subject on the left side is reflected by the mirror surface 1a of the prism 1 and then projected onto the left half of the solid-state image pickup device 4 through the lens 2a. Similarly,
The subject on the right side is reflected by the mirror surface 1b of the prism 1 and then projected onto the right half of the solid-state image sensor 4 through the lens 2b. Therefore, the left and right subjects can be viewed at once by the single solid-state image sensor 4.

In the above embodiment, the case where the prism 1 is used as the path changing means has been described, but the present invention is not limited to the prism 1, and the object image may be reflected or refracted to capture a plurality of objects. It suffices that the path change means and the lens are not integrally formed.

[0011]

As described above, according to the present invention, a plurality of subject images are guided by the path changing means for reflecting or refracting the subject images, and the plurality of subject images are separately collected by the plurality of lenses. , By forming a plurality of images on one solid-state image sensor from these lenses,
Since multiple image pickup devices can be viewed at the same time with a single image pickup device and the structure of this image pickup device is simple,
The cost can be reduced and the shape can be reduced.
