In this conventional example, the liquid crystal panel of the viewfinder is used for the projector, the backlight for the viewfinder and the light source for the projector are arranged on the same optical axis, and the backlight is used when the projector is used. It is configured to move away from the optical axis.

In addition, since the image on the front surface and the back surface of the liquid crystal panel viewed from the viewfinder and the projection by the projector are reversed, the image on the liquid crystal panel is projected in the case of projection by the projector. In addition to having to invert the sweep, it is necessary to incorporate a circuit for inversion, and a liquid crystal panel dedicated to inversion is also required.

[0004]

In the above-mentioned conventional example, a limited liquid crystal panel for inversion and a circuit for inversion are required, and especially the circuit for inversion is complicated including its driving device. At the same time, the liquid crystal panel dedicated to reversing becomes more expensive than a normal liquid crystal panel, and not only the video camera becomes expensive, but also an extra space for incorporating the circuit is required, which makes the camera compact. It has a problem that it goes against compactness.

Therefore, in the conventional example, an ordinary liquid crystal panel is used without using an expensive liquid crystal panel exclusively for inversion and a complicated inversion circuit, and a compact and compact structure can be obtained with a simple structure. However, there is a problem that must be solved to ensure that a proper image can be viewed even when projected by a projector.

[0006]

As a concrete means for solving the above-mentioned problems of the prior art, the present invention provides a video camera equipped with a viewfinder for illuminating a liquid crystal panel from the back side by a backlight so as to enlarge the view. A video camera characterized in that a means for rotating the liquid crystal panel by a predetermined angle and a light source and a projection lens are disposed in front of and behind the liquid crystal panel at the rotational position to provide a projector function. is there.

Further, the light source for the projector is arranged on the surface side of the liquid crystal panel rotated by a predetermined angle, and when the liquid crystal panel is used as a projector, the top and bottom of the liquid crystal panel can be seen through a viewfinder. It is a video camera in which it is turned upside down with respect to a viewing position, and light from a light source for a projector is reflected to enter a liquid crystal panel, and a mirror is used for the reflection.

Further, the liquid crystal panel is rotated by a predetermined angle of 90 ° to 180 °, and when the liquid crystal panel is used as a projector, the backlight of the liquid crystal panel is automatically turned off. The video light used for lighting the projector is also used as the light source for the projector, and the video light is a diffused light when the video lighting is used and a parallel light beam when used as the projector light source. ..

Further, the viewfinder is provided with a speaker that does not produce sound during video shooting, and the speaker is a video camera in which the inside of the viewfinder can be used as a speaker box.

[0010]

When the liquid crystal panel provided inside the viewfinder is used as a projector, the liquid crystal panel is rotated upside down and the projection light is transmitted from the front surface side of the liquid crystal panel to form a projection lens. This is the one that reverses the vertical and horizontal directions in the optical system of the above, and does not use the liquid crystal panel and the inversion circuit only for the inversion, and uses the normal liquid crystal panel (color) and looks into the viewfinder. Depending on the case and the case where it is used as a projector, by providing a rotating means for turning the liquid crystal panel upside down and changing the transmitting direction of the light for projection, it is possible to obtain a proper image at any time with a simple configuration. It can be projected anywhere.
