Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera having both a still camera (silver salt camera) function for taking a still picture and a video camera function for taking a moving picture.

[0002]

2. Description of the Related Art Conventionally, it is desired to shoot with a still camera that records a still image using a silver salt film while recording with a video camera that records a moving image on a recording medium such as a magnetic tape. There is a need. In order to meet such needs, various cameras having a configuration in which a video camera and a still camera are integrated have been proposed, and a specific example thereof can be found in US Pat. No. 3,546,378. However, the problem with a camera having this kind of complex function is how to use the viewfinder for a still camera and a video camera.

One method for solving this problem is Japanese Patent Publication No.
No. 55991, the electronic viewfinder section and the optical viewfinder section are switched by a mirror so that both the electronic viewfinder (EVF) and the optical viewfinder can be viewed at the same position. In addition, Japanese Patent Application Laid-Open No. 63-2 has been designed to be compatible with both still cameras and video cameras only with an optical viewfinder.
Japanese Patent No. 61330 has been proposed.

[0004]

However, since the technique disclosed in Japanese Patent Laid-Open No. 63-261330 described above uses only the optical finder, the zoom ratio (angle of view) on the video side and the zoom ratio on the still camera side are not provided. If and are different, you will be confused as to whether you are looking at the video or still field of view.

Further, in the zoom lens, 35 mm
The still camera targeting the silver salt film has a lens aperture larger than that of a video using an image sensor (CCD) with a small image circle. Therefore, a zoom lens for video can have a high magnification, while a still camera made of a silver salt film cannot have a large zoom ratio. On the other hand, the finder can support only one of them.

Furthermore, in the technique disclosed in the above-mentioned US Pat. No. 3,546,378, the light passing through one lens is split into the image sensor side and the film side by the mirror, and the optical path is also divided, so that the video On the other hand, the zoom ratio and angle of view on the still side are almost the same, but there is a problem in that the optical system must be adjusted to the image circle of a large format, and the optical system becomes huge. Especially when trying to make the zoom ratio of the silver salt system and the video system the same,
The reality is difficult.

Further, the technique disclosed in Japanese Patent Publication No. 2-55991 has a drawback that it lacks rapidity because it is used by switching between an electronic finder and an optical finder.

It is an object of the present invention to provide a camera capable of enhancing operability and quick-shooting characteristics while having an optical system having a desired zoom ratio on each of a video side and a still side.

[0009]

In order to achieve the above object, the invention described in claim 1 is a video camera section for recording a moving image on a first recording medium, and a still image for a second recording. Integrated with the still camera unit for recording on the medium, or 1
In a camera configured as one system, display means for displaying an image captured by the video camera part as a visible image, and an image displayed by this display means in a partial area in the optical viewfinder of the still camera part. An optical system having an optical element arranged to be guided and included in a part of the field of view of the optical finder in the middle of the optical path, and a non-translucent element arranged so as to overlap the optical element. And a light-shielding member moving mechanism that allows external selection of whether or not the light-shielding member and the optical element overlap with each other.

According to a second aspect of the present invention, the display brightness of the display means is changed according to the moving direction of the light shielding member moving mechanism.

Further, in the invention as set forth in claim 3, the display image by the display means is a photographed image and an information screen by numbers, characters, symbols, pictograms, etc. by the switching means which operates according to the selection by the user. I can switch to and.

Further, the invention according to claim 4 is provided with control means for automatically switching to the information screen when the function of the video camera unit is stopped.

[0013]

According to the camera of the first aspect, the video image on the video side is windowed and captured in a partial area in the optical viewfinder of the still camera section by silver halide photography, and the subject of the still camera section is captured by one viewfinder. It becomes possible to see the image and the video image on the video side at the same time. As a result,
Despite the configuration of the compound camera, it is possible to improve the quick-shooting property and the operability.

According to the second aspect of the present invention, when the light-shielding member moving mechanism is moved so that the light-shielding member and the optical element do not overlap with each other, the subject image by the still camera is displayed on the video side in the window of the finder screen. The video image is difficult to see because it overlaps with the video image. Therefore, the brightness of the video image on the video side can be increased by changing the brightness of the backlight of the display means, and the visual recognition of the video image becomes easy.

According to the camera of claim 3, in conjunction with the operation of the operation member provided on the camera body or the like, the window portion of the finder screen is required in the still camera portion instead of the video image on the video side. Information (numerals such as shutter speed value and aperture value, shooting mode, metering mode, focusing information, exposure correction information, symbols such as flash information, pictograms, etc.) is captured. Therefore, it is possible to eliminate the camera information display means such as a liquid crystal which is conventionally required in the optical viewfinder of the still camera unit, which is advantageous in terms of reduction of manufacturing cost and securing of space in the camera. Moreover, since the display area is large, a large amount of information can be displayed. According to the camera of claim 4, the display content of the window portion of the finder screen is automatically displayed on the video side when the video camera portion is not used. The video image of can be switched to the information required by the still camera unit. As a result, even if the still camera unit and the video camera unit are used properly, it is not necessary for the user to manually perform an operation such as screen switching, thus improving usability.

Next, how to use the camera having the above configuration will be described. (A) First, the lens unit L is mounted on the lens mount of the camera body 1. (B) Attach the camera unit 20 to the accessory shoe 5. (C) The camera unit 20 is attached to the socket 8 of the camera body 1.
The pin connector 24 of is inserted. (D) The mounting screw 35a of the operation unit 30 is screwed into the screw hole 7a of the back cover 7 to attach the operation unit 30 to the camera body 1
Fixed to the back of. (E) The video deck section 40 is stored in a jacket pocket or the like. (F) Rotate the mode dial 1a of the camera body 1,
From the OFF mode to the usable state, for example, the auto mode or the aperture priority mode is set. (G) Slide the trigger button cover 32 of the operation unit 30 to turn on the entire video unit. At this time, the camera unit 20 and the operation unit 30
Also, the VCR 40 operates using the battery in the VCR 40 as a power source. In this case, the LCD unit section 9 in the camera body 1 is also driven by the battery of the video deck section 40 via the connector 24, and the battery consumption in the camera body 1 is prevented. Under this condition, the viewfinder image seen by the eyepiece optical system 6 is as shown in FIG. (H) When the slide knob 10 is slid in the direction of the arrow in FIG. 2, the light shielding plate 10a overlaps the half mirror 17. (I) Since the subject image that has passed through the lens unit L is blocked by the light blocking plate 10a, the half mirror 17 loses the light from the rear, and the half mirror 17 functions as an almost total reflection mirror, as shown in FIG. In the eyepiece optical system 6, only the LCD image B can be seen.

In order to make the LCD image B in FIG. 4 easier to see, the LCD 15 may be illuminated by the backlight 15a. In this case, since the light path of the optical viewfinder is cut by overlapping the light shielding plate 10a on the half mirror 17, the LCD image B is displayed on the backlight 15.
Even if the brightness of a is low, it becomes easy to see. Therefore, in order to save energy, control is performed to automatically shift the backlight 15a to the low brightness side as described later. (J) When the trigger switch 34 of the operation unit 30 is pressed while both the camera body 1 side and the video side are turned on, the subject image in the visual field of the camera unit 20 becomes the video in the video deck section 40. Recorded on a cassette tape. (K) Then, when the release button 3 of the camera body 1 is pressed, the shutter mechanism of the camera body 1 is activated and the subject image that has passed through the lens unit L is exposed on the film surface.

Although the LCD image B is displayed on the eyepiece optical system 6, if the change button 11 is pressed at this time, the optical system 2 is displayed.
Instead of the image passed through 1, the shutter speed, aperture, date, etc. are displayed as shown in FIG. Change button 1
By pressing 1 again, the LCD image B will be displayed as shown in FIG.
Is displayed. Such switching of the contents of the LCD image B is performed by a visual line input mechanism (when the user looks into the eyepiece optical system 6 and gazes at a designated portion in the finder screen, instead of or in combination with the switch operation. It can also be performed by a mechanism for detecting and switching the screen.

Next, referring to the flow chart of FIG.
The brightness changing process of the image of the CD 15 will be described. In addition, in the following flowcharts, steps are represented by "S".

Here, it is assumed that the backlight 15 can be adjusted in brightness in two steps. First, the trigger button cover 32 is operated to turn on the power (S701). Next, external light is measured by the AE (automatic exposure) function of the video unit (S702). Further, it is determined whether or not the measured external light is brighter than a predetermined brightness (S703), and when this determination condition is satisfied, the light shield plate 10a is behind the half mirror 17 (that is, the light shield plate 10a). And the half mirror 17 overlap each other) (S70)
4). When the light shielding plate 10a does not overlap the half mirror 17, the LCD image B becomes difficult to see due to the effect of the subject image that has passed through the lens unit L, and thus corresponds to the second brightness level with respect to the backlight 15a. Lighting control is performed to increase the brightness (S706). Also, the light shielding plate 1
If it is determined that 0a and the half mirror 17 are overlapped with each other, the backlight 15a is subjected to lighting control corresponding to the first brightness level to reduce the brightness (S705).

Next, referring to FIG. 8, the LCD 1 in a state in which the video side is turned off and the still camera side is turned on.
The image brightness changing process of No. 5 will be described.

First, a main switch (not shown) of the camera body 1 (silver salt camera) is turned on (S801). Next, photometry is performed by the AE mechanism in the camera body 1 (S8
02). It is determined whether or not this photometric result exceeds a preset brightness level (S803), and if it exceeds, it is determined whether or not the light shielding plate 10a is in a position overlapping the half mirror 17 (S804). When the light shielding plate 10a and the half mirror 17 are overlapped, and when it is determined in step 803 that the brightness is lower than the reference brightness level, the backlight 15a is controlled to be turned on at the first brightness level (S805) to increase the brightness. . If it is determined in step 804 that the light shielding plate 10a does not overlap the half mirror 17, the backlight 15a is controlled to be turned on at the second brightness level (S806), and the brightness is reduced.
