DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video / still camera having a video shooting function and a still shooting function, and more particularly to a video / still camera using a photosensitive film.

[0002]

2. Description of the Related Art In general, a video camera is used to shoot a moving image, and a developing still camera is used to shoot a still image. For this reason, conventionally, when it is desired to take both a moving image and a still image, both the video camera and the still camera must be carried, which is very inconvenient.
In particular, a still image of a development type is often used for capturing a still image in terms of resolution, and the still image capturing function of a video image cannot be used in some cases.

[0003] In view of this, there has been proposed a photographing apparatus in which a video camera and a still camera are integrated. This photographing apparatus is configured by using a single-lens reflex camera as a mother body, in which a prism finder of the single-lens reflex camera is removed, and a video camera is combined therewith. The light captured by the lens of the single-lens reflex camera is divided into two directions, a film and a finder, and the image shown in the finder is taken into the video camera as it is. With this, you can usually shoot video by looking through the viewfinder of the video camera, and press the shutter of the SLR camera when necessary,
Only the crucial moments can be captured in high-resolution photos.

[0004]

However, the above-mentioned photographing apparatus is large in size and complicated in operation because the video camera and the single-lens reflex camera are simply combined.

[0005] The present invention has been made in view of such a point, and has both functions of shooting moving images and still images.
Another object of the present invention is to provide a small and lightweight video / still camera.

[0006]

According to the present invention, in order to solve the above-mentioned problems, in a video / still camera having a video shooting function and a still shooting function, a film storage for storing a photosensitive film for still shooting. Unit, an image sensor for video shooting, a light receiving lens mechanism for receiving and separating light from an object to be shot, and sending them to the photosensitive film side and the image sensor side, respectively, and a photosensitive film in the film storage unit , A still photographing mechanism for projecting the received light onto a part of the photosensitive film, a video photographing mechanism for projecting the received light to the image sensor, and storing an image captured by the image sensor. And a small-sized storage medium in the same case.

In such a video / still camera, the light receiving lens mechanism receives and separates light from the object to be photographed, and sends the light to the photosensitive film side and the image sensor side. The still photographing mechanism sends the photosensitive film stored in the film storage unit and projects the received light onto a part of the photosensitive film. On the other hand, the video photographing mechanism projects the received light onto the image sensor. The image captured by the image sensor is stored in a small storage medium.

[0008] Thus, the function of capturing a moving image by a video camera and capturing a still image by a still camera is realized by one camera. In addition, since each function is provided in the same case, the size of the entire camera is reduced.
