Abstract

PURPOSE:To prevent a video signal on a recording medium from being broken even when a subject image is photographed on a photosensitive film where a video signal recording means is stopped temporarily when a shutter button is operated. CONSTITUTION:When the shutter button 26 is operated, a shutter signal generation part 28 supplies a shutter signal Ss to a control signal generation part 14 and also supplies a stop signal Si for stopping (pausing) a VTR 24 temporarily. Thus, the video signal is prevented from being broken on the recording medium by the simple constitution even when the subject image is photographed on the photosensitive film 18a during the recording of the video signal of the subject image by the VTR 24, and a visual break of video in video reproduction can securely be precluded.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an image photographing device that integrates a video camera and a still camera.

[Summary of the Invention] The present invention relates to an image photographing device that integrates a video camera and a still camera, and includes a lens means into which light from a subject enters, and an image of the subject obtained on a light receiving surface by the light passing through the lens means. A photoelectric conversion means that generates a video signal according to the image; a film mounting section to which a photosensitive film member is attached that obtains an image of the subject using the light that has passed through the lens means; a movable mirror that selectively takes a first state in which it guides the photosensitive film member and a second state in which it guides it toward the photosensitive film member; a video signal recording means that continuously records video signals; Since the video signal recording means is configured to temporarily stop when the shutter button is operated, the video signal of the subject image can be recorded by the video signal recording means with a simple configuration. Even when a subject image is photographed using a photosensitive film during recording, the video signal is not interrupted on the recording medium.

[Prior Art] Conventionally, a video camera that obtains a video signal by photographing a moving subject generally transmits light that has passed through an objective lens to the light-receiving surface of a photoelectric conversion means using an image pickup tube or a solid-state image sensor. A video signal is formed based on an imaging signal obtained according to a subject image formed on the light receiving surface of the photoelectric conversion means, and the formed video signal can be used, for example, as a video signal recording means. The information is sequentially recorded on a recording medium such as a magnetic tape of a video tape recorder (VTR). In this way, the video camera is equipped with a photoelectric conversion means, and the photosensitive film member receives the light from the subject, and the photosensitive film member receives the light from the subject. A camera that is integrated with a still camera that forms a subject image on top has been proposed. In this case, a still camera captures and photographs the subject as a still image, but if a still image is taken while shooting with a video camera, the video signal is interrupted on the recording medium in a VTR, and the image is not visually visible during video playback. It will be interrupted. Therefore, the present applicant proposed an image capturing device that can prevent this interruption of video (Japanese Patent Laid-Open No. 62-18
No. 3275).

[Problem to be solved by the invention]

However, this image capturing device is limited to 1. storing the video signal obtained from the photoelectric conversion means. q section (memory), and this storage section prevents video interruption during video playback based on the video signal on the recording medium immediately before the stored still image, so the configuration is complicated. There was an inconvenience.

In view of the above, the present invention has a simple configuration that reliably prevents interruptions in the video signal on the recording medium even when the image of the subject is photographed with a photosensitive film while the video signal of the subject image is being recorded by the video signal recording means. The purpose is to propose an image capturing device that can.

〔Example〕

An embodiment of the image capturing device of the present invention will be described below with reference to FIGS. 1 and 2.
This will be explained with reference to the figures.

This example shown in FIG. 1 has a lens part (2) and a main body part (4), and a lens means (6) is provided in the lens part (2).
is further provided with an aperture mechanism (8) for restricting the subject light (1) (indicated by a dashed line in FIG. 1) entering the lens means (6). This diaphragm mechanism (8) has a control signal generator (
The aperture value is controlled by an aperture drive unit (11) that operates in response to an aperture control signal Sl supplied from 10);
Thereby, an appropriate aperture value can be obtained depending on the brightness of the subject to be photographed.

Inside the main body (4), there is a first state located at the position shown by the solid line in FIG. 1 in order to change the path of the subject light (1) passing through the lens means (6), and A movable mirror (12) is disposed that can selectively assume a second state shown by a two-dot chain line. This movable mirror (12) assumes a first state, for example, when the mirror control signal Sm supplied from the control signal generator (14) to the mirror drive unit (13) has a predetermined low level; The second state is assumed when the control signal Sm takes a predetermined high level. That is, in this example, the mirror drive section (13), control signal generation section (14), etc. constitute the mirror control section.

Then, with the movable mirror (12) placed at the position shown by the solid line, the object light (1
) is arranged at the position where the photoelectric conversion means (16) configured using a CCD (charge-coupled device) image sensor or the like is arranged, and the subject light (1) is transmitted to the light receiving surface of the photoelectric conversion means (16) I can accept it. Further, when the movable mirror (12) is placed at the position indicated by the two-dot chain line, a photosensitive film (18a) is attached to the position where the subject light (1) passing through the lens means (6) reaches. A mounting portion (18) is provided. Furthermore, when the movable mirror (12) is placed on the exposure surface side of the photosensitive film (18a) at the position shown by the two-dot chain line, the subject light (12) is applied to the photosensitive film (18a).
) is provided with a shutter (19) that limits the period during which the light is incident. This shack (I9) has a control 0 signal generation section (
14) is controlled by a shutter drive unit (15) supplied with a mirror control signal Sm, for example, it is normally in a closed state, and from the time when the mirror control signal Sm takes a predetermined high level, a predetermined After a period of time has elapsed, it is operated to be in an open state for a set period of time, and subject light (1) is made to enter the photosensitive film l (18a).

A photoelectric conversion means (16) is provided on the output side of the photoelectric conversion means (16).
) is connected to a video signal forming section (22) that forms a video signal Sv based on the imaging signal Sc obtained in step 1. The output side of the video signal forming section (22) is connected to a video signal recording means, such as a VTR (24) that is equipped with a pause mechanism and that continuously records video signals. There is. Further, the video signal Sv formed in the video signal forming section (22) is transmitted to the control signal generating section (10).
The control signal generating section (10) forms an aperture control signal SZ corresponding to the peak level of the video signal Sv and supplies it to the aperture driving section (11).

Further, the main body (4) has a shutter (
19), and when the shutter button (26) is operated, a shutter signal Ss is sent from the shutter signal generator (28) to the control signal generator (14). V
A stop signal St that causes TR (24) to stop (pause) is supplied. And the movable mirror (12) is the first
When the state returns to , a release signal from a release switch (30) provided near this movable mirror (12) causes V
At TR (24), the pause is released.

The operation timings of the VTR (24), movable mirror (12), and shutter (19) at this time are as shown in FIG.

That is, when the shutter button (26) is operated, the VTR (2
4) switches from the recording state to the pause state, and at the same time the movable mirror (12) moves up (
(first state) to down (second state), and in the shack (19) from off to on. While this shutter (19) is on, it becomes a shutter speed, and the pause can be released by detecting the return of the movable mirror (12), but the maximum shutter speed of a still camera is limited to long exposure. If the shutter speed is high and does not have this function, automatic release may be performed using a timer equal to the maximum shutter speed plus the operation time of the quick return operation of the movable mirror (12). In addition, in the case of a VTR (24), there may be a time lag in the operation of the shutter mechanism, and the time it takes to enter the pause state may become a problem. When pressing (26) V T
On the R (24) side, the tape may be rewound slightly before entering the pause state.

In this way, in this embodiment, the shutter button (26
), the VTR (24) enters a pause state, so with a simple configuration, when the VTR (24) is recording the video signal of the subject image and the subject image is photographed with the photosensitive film (18a). Therefore, it is possible to prevent the video signal from being interrupted on the recording medium, and therefore, it is possible to reliably prevent the video from being visually interrupted during video playback.

Note that the present invention is not limited to the above-mentioned embodiments,
Of course, various configurations can be made without departing from the gist of the present invention.

Even when a subject image is photographed using a photosensitive film, interruptions in the video signal on the recording medium can be prevented, and there is an advantage that interruptions in the visual image during video playback can be reliably prevented.
