Figure) G-2 Second Embodiment (Figures 3 to 5) G-3 Modification Effect of the Invention A Industrial Field of Application The present invention is based on an imaging output signal obtained by photographing an image. The present invention relates to an image photographing device that transmits a formed video signal and displays a reproduced image screen obtained based on the transmitted video signal using a viewfinder.

B. Summary of the Invention The present invention provides a signal forming output section that forms and sends out a video signal based on an imaging output signal from an imaging section, and a view that displays a reproduced image screen obtained based on the sent out video signal. In an image photographing device having a finder section, the signal forming output section is configured to produce a first video signal and a second aspect ratio that will provide an appropriate reproduced image screen based on the first aspect ratio. A video signal forming section is formed to form a second video signal that provides an appropriate reproduced image screen, and selectively sends out the first video signal and the second video signal. None, and when the viewfinder section is displayed to display a reproduced image screen obtained at the first aspect ratio based on the first video signal, at least the signal forming output section When the second video signal is selectively transmitted, a frame indicating the range of the reproduced image screen obtained under the second aspect ratio based on the second video signal is displayed on the resulting reproduced image screen. By making it so that the first video signal is selectively transmitted from the signal forming output section by the - number of viewfinder sections, and when the second video signal is selectively transmitted from the signal forming output section, , the reproduced image screen obtained based on each video signal can be appropriately displayed.

C. Prior Art Conventionally, in many television systems, the reproduced image screen has an aspect ratio of 4:3.

In this way, under the television system in which the reproduced image screen has an aspect ratio of 4:3, an imaging device, that is, a video camera, can display a subject within a screen with an aspect ratio of 4:3. An imaging output signal corresponding to the image within the screen is obtained, and a video signal formed based on the obtained imaging output signal is sent out.

However, with the increasing use of reproduced images from television signals, the aspect ratio of the reproduced image screen has changed from 4:3 as shown by the solid line in FIG. expanded to the 6th
For example, it has been proposed that the aspect ratio be 16=9, as shown by the dashed line in the figure.

In order to obtain a video signal capable of obtaining a reproduced image screen with such an aspect ratio of 16:9, for example,
A video camera captures a subject as being within a screen with an aspect ratio of 16=9, obtains an imaging output signal corresponding to the image within the screen, and forms a video signal based on the obtained imaging output signal. It is said that The video signal that can produce a reproduced image screen with an aspect ratio of 16:9 obtained in this way has an aspect ratio of 4=4.
Compared to the video signal that can obtain the reproduced image screen of No. 3, for example, the amount of information in the horizontal scanning direction is increased and the occupied frequency band is expanded by adding a high frequency component. It is said that

For this reason, there is a function for transmitting a video signal that can obtain a reproduced image screen with an aspect ratio of, for example, 16:9, and an aspect ratio of, for example, 4=3 for the subject. There is a need for a video camera that is equipped with the function of transmitting a video signal capable of obtaining a reproduced image screen that can be selectively performed.

D. Problems to be Solved by the Invention In a video camera, a viewfinder is installed in a fishing boat to check the imaging range of the subject at the time of imaging. In order to fulfill its function as a viewfinder by making it possible to check the video signal itself sent out from the video camera, it displays a reproduced image screen obtained based on the video signal sent out from the video camera. An image reproduction viewfinder has been proposed.

An image playback viewfinder is an independent image playback device that is supplied with a video signal sent from a video camera and can reproduce a playback image based on the video signal, so the aspect of the image screen displayed by it is The ratio is not automatically determined by the supplied video signal, but is set in advance.

Such an image reproduction viewfinder adjusts the aspect ratio of the subject to, for example, 16:9 as described above.
When applied to a video camera that can selectively transmit a video signal capable of obtaining a reproduced image screen with an aspect ratio of 4=3, and a video signal capable of obtaining a reproduced image screen with an aspect ratio of 4=3, When a video signal that allows a reproduced image screen with an aspect ratio of 16=9 is sent out from a video camera, the display representing the reproduced image screen based on the video signal has an aspect ratio of 16=9.
:9, and if a video signal is sent from a video camera that allows a reproduced image screen with an aspect ratio of 4:3, it represents the reproduced image screen based on that video signal. Display aspect ratio is 4:3
Ideally, it should be done under the following conditions.

However, if the aspect ratio of the image screen displayed by the image playback viewfinder is set in advance, it is difficult to achieve the above ideal when one image playback viewfinder is used. When a video signal is sent from the video camera that allows a playback image screen with an aspect ratio of 16:9 to be obtained, and when a video signal is sent that allows a playback image screen with an aspect ratio of 4:3 to be obtained from the video camera. In one of the cases where the signal is sent out, the display representing the reproduced image screen made by the image reproduction viewfinder will not be displayed with an appropriate aspect ratio.

In view of the above, the present invention provides a first video signal that is formed based on an imaging output signal obtained from an imaging unit and is capable of obtaining a reproduced image screen having an aspect ratio of 16:9, for example; For example, a second video signal capable of obtaining a reproduced image screen with an aspect ratio of 4:3 is selectively transmitted, and the first video signal is selectively transmitted by - viewfinder sections. An image capturing device capable of substantially displaying a reproduced image screen obtained based on each video signal with an appropriate aspect ratio, both when the second video signal is selectively transmitted and when the second video signal is selectively transmitted. The purpose is to provide

E.

The frame display control section includes a viewfinder section that performs display and a frame display control section related to the viewfinder section, and the frame display control section at least selects and sends out the second video signal to the viewfinder section. On the resulting reproduced image screen, a frame indicating the range of the reproduced image screen obtained at the second aspect ratio based on the second video signal is displayed.

F Effect In the image photographing device 1 according to the present invention configured as described above, the video signal selection unit obtains the first reproduction image screen based on the first aspect ratio. When the video signal is selectively transmitted, the viewfinder section displays a reproduced image screen obtained at the first aspect ratio based on the first video signal, and the video signal selection section displays the reproduced image screen obtained at the first aspect ratio. , a second aspect ratio in which an appropriate reproduced image screen is obtained based on the second aspect ratio.
When a video signal is selectively transmitted, a display representing a reproduced image screen obtained at a first aspect ratio based on the first video signal is displayed in the viewfinder section, and a second video signal is superimposed thereon. A frame indicating the range of the reproduced image screen obtained under the second aspect ratio based on the second video signal is displayed, and the display portion within the frame indicates the second aspect ratio based on the second video signal. The reproduced image screen obtained under the ratio is substantially distorted.

Therefore, in the image photographing device according to the present invention, the first viewfinder section selects the first
