Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an imaging device such as a video camera or a video movie.

2. Description of the Related Art In recent years, along with video decks, video movies have become widely used as imaging devices in homes. Images taken with a video camera are played back on the camera body or video deck, and displayed on a monitor television as shown in FIG. In addition, as screens become larger, there are also LCD projection televisions that use transmissive LCD panels.

Conventionally, many video cameras have had monochrome viewfinders, or in recent years, color viewfinders using color liquid crystals or CRTs have been introduced.

Problems to be Solved by the Invention In such conventional imaging devices, when playing back the captured screen, the only way is to look directly at the viewfinder, and many people can view the playback screen at the same time without using a monitor TV. If you are watching with a large number of people, you will need to prepare a separate TV station. therefore,
It is not possible to enjoy the playback screen easily with just an imaging device.

The present invention solves the above problems, and aims to provide an imaging device that is small, lightweight, and inexpensive, and has a reproduction screen projection function.

Means for Solving the Problems In order to achieve the above object, the present invention is configured to provide an optical conversion means and project an image on a display element by converting an imaging optical system into a projection optical system.

Operation According to the present invention, the imaging optical system functions as a projection optical system due to the above-described configuration.

Embodiment Hereinafter, an imaging apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIGS. 1(a) and 1(b) are partial sectional views showing the configuration of an imaging device according to an embodiment of the present invention.

In the figure, 1 is an imaging optical lens, and 2 is C as a component.
An image pickup device such as a CD, 3 a recording/playback section for recording and playing back signals, 4 a liquid crystal panel as a display element, 5 a liquid crystal panel light, 6 an eyepiece, and 7 a folding mirror (optical conversion means). be.

To explain the relationship and operation of each of the above components, during normal shooting, as shown in Figure 1(a),
A subject image is formed on a CCD 2 by an imaging optical lens 1 and recorded. During imaging, the liquid crystal baffle 4 functions as a viewfinder and displays the image using the signal output from the recording/playback section 3. At this time, the folding mirror 7 is in a position where it does not interfere with the imaging optical system. As shown in FIG. 1(b), the image plane of the display liquid crystal panel is folded back and placed on the optical axis of the imaging optical lens l by changing the attitude of the folding mirror 7 provided as an optical conversion means. The image reproduced on the liquid crystal panel is projected forward by the imaging lens 1 using the backlight 5 as a light source. This imaging device functions as a projection television. In this case, due to the design in which the lower part of the screen of the liquid crystal panel 4 is shifted near the center of the lens 1, the lower part of the screen does not move even when the imaging optical lens 1 is zoomed, and is expanded or contracted upward and left and right. , convenient for projection on a tabletop. If the sizes of the CCD 2 and the liquid crystal panel 4 are different, a conversion lens may be incorporated into the optical system.

Note that if a cathode ray tube display element (CRT) is used as the display element 4, the backlight 5 becomes unnecessary.

According to the imaging device of the above embodiment, by providing an imaging device with an optical conversion means, an imaging device having a projection function that allows viewing by multiple people at the same time can be converted into a projection optical system. It can be shared, making it compact and cost-effective.

Effects of the invention As is clear from the above embodiments, the imaging optical lens and
an imaging device on which the imaging optical lens forms an image; a recording and reproducing unit that records signals from the imaging device or plays back images;
In an imaging device including a display element for a viewfinder that displays an image based on a signal from the recording/playback section, an optical conversion means is provided, and the optical conversion means converts the imaging optical lens into the imaging element when capturing an image. Forms an optical path to form an image,
By using an imaging device that forms an optical path to project the image of the display element to the outside through the imaging optical lens during projection, the imaging device has a projection function that allows multiple people to view the image at the same time. By sharing the system with the projection optical system, the system can be made compact and advantageous in terms of cost.
