Abstract

<P>PROBLEM TO BE SOLVED: To simultaneously view both front and rear targets to be imaged on a color liquid crystal display 20 in a portable telephone with a camera. <P>SOLUTION: Light incident from the front side target to be imaged through a convex lens 30 is reflected on a mirror part 100 and made incident to a camera device 90, and light incident from the rear side target to be imaged through a convex lens 80 is reflected on a mirror part 110 and made incident to a light receiving plane 91 of the camera device 90. Since both reflected light beams are mutually offset and made incident to the light receiving plane 91 of the camera device 90, the camera device 90 stores charges on the basis of both incidental light beams. In accordance with this storage, a driving part 120 detects a quantity of charges stored in the camera device 90 and outputs detected data through a storage part 140 to the color liquid crystal display 20. <P>COPYRIGHT: (C)2003,JPO

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for photographing a camera and displaying the photographed image.

[0002]

2. Description of the Related Art For example, in a digital camera, a liquid crystal display is provided on the front side of a case, and a CCD (charge coupled) for shooting an image object on the back side of the case.
There is one in which a device) is provided, an object to be imaged by this CCD is displayed on a liquid crystal display, and this liquid crystal display is made to function as a finder of a camera.

However, such a liquid crystal display and C
Even if only the CD is provided, the projection target on the opposite side of the liquid crystal display can be projected, but the projection target on the liquid crystal display side and the projection target on the opposite side cannot be projected at the same time. Therefore, it is desired that the imaged objects in different directions are simultaneously imaged and that both of the imaged objects to be imaged can be visually recognized simultaneously on the liquid crystal display.

In view of the above points, it is an object of the present invention to provide a camera capable of simultaneously projecting imaged objects in different directions so that both imaged objects can be visually recognized by the display means at the same time. And

And the second mirror unit are arranged, and when the conversion unit converts the light reflected from the first and second mirror units into an electric signal, the first and second mirrors are generated based on the converted electric signal. It is characterized by having a control means (150) for displaying the object to be imaged on the same frame screen of the display unit.

As described above, the first and second mirror portions are arranged so that the light reflected from the first mirror portion and the light reflected from the second mirror portion are offset and incident on the light receiving surface. Has been done. Therefore, it is possible to display the imaged objects in different directions on the same frame screen of the display unit with a simple configuration including one conversion unit and the first and second mirror units.
