DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera, a video camera system, a shooting method, a video signal processing method, and a storage medium, and more particularly to a video camera configured to be able to shoot a moving image and a still image simultaneously. It is suitable.

[0002]

2. Description of the Related Art Conventionally, a video camera generally uses a tape as a medium for recording moving images and a solid-state memory as a medium for recording still images. Such a video camera is disclosed in, for example, Japanese Patent Application Laid-Open No. 8-2986.
No. 44.

The present inventor has previously proposed a finder screen configuration in which a sub-screen is inserted and displayed in a main screen, but this is for displaying a liquid crystal in an optical finder. Configuration.

[0004]

However, the above-mentioned prior art has the following disadvantages. That is, JP-A-8-2
The invention described in Japanese Patent No. 98644 is described as a video camera having a magnetic tape as a medium for recording a moving image and a solid-state memory such as a memory card as a medium for recording a still image. Almost no description is given on display, viewfinder display and reproduction.

On the other hand, the invention proposed by the present inventor before is
This is a method of displaying images by inserting them into the optical viewfinder, and there is a problem that only one screen can be inserted. In addition, there is a problem that both images cannot be output to the reproduction screen and searched.

SUMMARY OF THE INVENTION In view of the above-described problems, it is a first object of the present invention to provide a method for visually recognizing that a still image has been shot while a video camera is shooting a moving image. I do. It is a second object of the present invention to make it possible for a photographer to recognize that a still image has been photographed while a moving image is being reproduced.

[0007]

According to a first aspect of the present invention, there is provided a video camera including first and second recording media for recording a moving image on the first recording medium. When a still image is recorded on the second recording medium while a moving image is recorded on the first recording medium in a video camera that records a still image on the second recording medium, It is characterized by having display control means for inserting and displaying a still image in a display screen displaying a moving image therein.

The video camera system of the present invention records video signal information on a first recording medium and video signal recording means for recording still image information on a second recording medium. And a video signal reproducing means for reproducing the video signal recorded on the recording medium 2 and displaying the video signal on the display means.
When a still image is recorded on the second recording medium while a moving image is being recorded on the recording medium, timing storage means for storing the timing at which the still image is recorded; When the moving image recorded on the medium is being reproduced, the reproduction control means for inserting and displaying a still image for a predetermined time in the moving image reproduction screen at the timing recorded in the timing storage means. It is characterized by having.

A photographing method according to the present invention comprises a first recording medium and a second recording medium, wherein a moving image is recorded on the first recording medium and a still image is recorded on the second recording medium. When a still image is recorded on the second recording medium while a moving image is being recorded and recorded on the first recording medium, the still image is displayed on the display screen displaying the moving image being photographed. It is characterized in that display control processing for inserting and displaying a picture image is performed.

The video signal processing method according to the present invention includes a video signal recording process for recording a moving image on a first recording medium and a still image on a second recording medium; And a video signal reproducing process for reproducing and displaying a video signal recorded on the recording medium of the first aspect, wherein the second recording is performed while the moving image is being recorded on the first recording medium. When a still image is recorded on the medium, a timing storage process for storing a timing at which the still image is recorded, and when the moving image recorded on the first recording medium is reproduced, the still image is recorded. At the specified timing, a display control process of inserting a still image for a predetermined period of time and displaying it in the playback screen of the moving image is performed.

[0011] The storage medium of the present invention is characterized by storing a program for causing a computer to function as each of the above means. Another feature of the present invention is that a program for causing a computer to execute the above method is stored.

[0012]

Since the present invention has the above technical means, if a still image is shot while a moving image is being shot by a video camera, the still image is displayed on a part of the display screen displaying the moving image being shot. Since the image is inserted and displayed, it is possible to visually recognize that the still image has been shot. As a result, even if the user is absorbed in shooting a moving image and forgets what still image was shot, it is possible to prevent a similar still image from being shot twice. Also, when playing back and watching a movie, a still image is inserted and displayed for a predetermined time in the screen of the movie being played back when shooting a still image, so the photographer is notified that the still image was shot. It becomes possible to make them recognize.
