Abstract

PURPOSE:To confirm the respective kinds of photographic condition information and to improve operability by simultaneously displaying both video photography information and picture photography information on a view finder. CONSTITUTION:The view finder shows a set mode of video photography as 4a and remaining time of a video tape as 4b and respectively shows flash photography of picture photography as 4c, focused state as 4d, iris value as 4e, shutter speed as 4f and use conditions of a film as 4g. Further, a date 4h is displayed as information common for both of video photography and picture photography. Thus, since the information of video photography and picture photography is simultaneously displayed on the view finder, both of information can be simultaneously confirmed, and operability can be improved.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing device in which a video camera and a camera are integrated.

[0002]

2. Description of the Related Art Conventionally, a user has a video camera and a photographic device separately and uses them separately. Alternatively, there have been proposed ones that are configured in the same housing in a grip of a video camera or in parallel with each other in the camera, or ones in which a camera can be attached to an accessory shoe of the video camera.

[0003]

However, the above-mentioned conventional example has the following drawbacks because the video camera and the photographic device are controlled separately. During video recording, I could not confirm the number of remaining films in the camera, the exposure conditions, and the shooting conditions such as the presence or absence of a flash. During the picture taking, I could not confirm the information about the video taking such as the remaining time of the video tape and the state of the mode setting. The position and size of the character imprinted on the photograph with respect to the subject could not be confirmed until the photographic film was removed and developed. Therefore, it was difficult to determine the composition of the photograph.

The present invention has been made to solve the conventional problems, and an object of the present invention is to provide a photographing apparatus capable of easily confirming information such as photographing conditions of video and photographs.

[0005]

In order to achieve the above-mentioned object, the photographing apparatus of the present invention, in claim 1, has an image input means and a plurality of recording means sharing the image input means in the same housing. In the photographing device provided in the above, the status information of the plurality of recording means is displayed on one confirmation means, and the subject confirmation means of each recording means is shared by one confirmation means. It was done,
Further, in claim 3, the relationship between the position and size of the character and the subject generated by the confirmation means and the relationship between the position and size of the character and the subject recorded on the medium of one recording means have the same ratio. It was made to be.

[0006]

According to the first aspect of the present invention, by simultaneously displaying the video shooting information and the photography information on the viewfinder, the respective information can be confirmed at the same time, and the operability of the apparatus is improved. . Further, according to the second and third aspects, the relationship between the position of the character displayed in the viewfinder and the position and size of the character imprinted in the photograph with respect to the subject is the same, so that the photographic film is not developed. However, the composition of the photograph can be confirmed.

The optical system of this apparatus will be described in more detail.

The optical system of the present apparatus has one entrance pupil for a subject and is divided by a semitransparent thin film mirror 30 into a camera side and a video camera side. At this time, if the image-forming portion of the photographic film 22 is in focus, the solid-state image-pickup element 33 must always be in-focus, and this apparatus is installed so as to be optically and mechanically as described above. ing. The amount of focus shift of the present apparatus is detected by comparing the contrast of the video signal obtained from the solid-state image sensor 33 and applying some types of fuzzy rules, which are fed back to control the DC motor and the like of the focus control unit 40. To do. Further, as the aperture control, area division photometry such as the central portion of the solid-state image sensor or total photometry can be arbitrarily performed, and the photometry can be selected depending on each usage environment, and the aperture control unit 42 can always be controlled well. it can.

The zoom control can be set by the user with the zoom button 19 while looking through the viewfinder 4. In the shutter control, by rotating the shutter button 18, the user can select various photography modes such as aperture priority AE, shutter speed priority AE, and program AE. Further, based on the result of photometry by the solid-state image pickup device 33, the shutter speed is controlled by the shutter control unit 44, and the aperture control is performed by the aperture control unit 44 to perform a predetermined exposure on the photographic film surface. At this time, when the aperture control is performed, the illuminance on the image forming surface of the solid-state image sensor 33 changes, so the image sensor control unit 43 controls the gain of the solid-state image sensor 33.

Next, the viewfinder, which is a feature of the first embodiment of the present invention, will be described. FIG. 10 is a diagram showing an example displayed on the viewfinder 4 as one embodiment of the present invention, in which 45 is a subject, 4a is a video shooting setting mode, and 4b is a remaining time of the video tape. 4c indicates flash photography, 4d indicates a focused state, 4e indicates aperture value, 4f indicates shutter speed, 4g indicates usage of photographic film, 4h.
Indicates the date. 4a and 4b are information necessary for video shooting, 4c, 4d, 4e, 4f and 4g are information necessary for photo shooting, and 4h is information common to both video shooting and photo shooting. In this way, the viewfinder can obtain the video shooting information and the photography information at one time.

Next, the relationship between the position and size of the character according to the second embodiment of the present invention will be described. FIG. 11 is a diagram showing an example in which the subject and the character confirmed by the viewfinder 4 as the second embodiment of the present invention are projected, and FIG. 12 shows the subject confirmed by the viewfinder 4 described above. It is the figure which illustrated the photograph when the shutter was released at the moment. Although the size of the angle of view and the aspect ratio are different between FIG. 11 and FIG. 12, in the example of this figure, the relationship between the position and the size of the character and the subject of 92.4.27 is set to be the same, and the photograph is immediately taken. You can see the character being photographed above.

[0021]

As described above, according to the first aspect of the present invention.
According to the method, by displaying the video shooting information and the photo shooting information on the viewfinder at the same time, the video shooting information and the photo shooting information can be checked at the same time, and the operability is improved.

According to claim 2 and claim 3, by matching the relative relationship between the character in the viewfinder and the object and the relative relationship between the character in the photograph and the object,
You can check the positional relationship of the characters before developing the photo,
This has the effect of facilitating composition during shooting.
