The present invention relates to a still camera integrated video camera, and in particular, a video camera using magnetic tape as a recording medium, and a still camera using a photographic film made of silver salt film as a recording medium. The present invention relates to a still camera integrated video camera capable of easily photographing a camera.

Background Art Conventionally, video cameras that magnetically record moving images on magnetic tape and still cameras that expose still images on photographic film have been developed as individual products. However, if you want to capture the same subject with a video camera and still take a picture with a still camera, carrying both a video camera and a still camera is cumbersome, and if you do not stop shooting with a video camera, No way.

Therefore, the still camera integrated video camera which integrates a video camera and a still camera is continuously developed. As such a still camera integrated video camera, there is one disclosed by Japanese Patent Laid-Open No. 63-261330. This publication has a structure in which a still camera is installed on the left side of the housing while the box-shaped housing is viewed from the front, and a video camera is installed on the right side of the housing. A still camera objective lens and a video camera objective lens are disposed on the front of the housing, and an objective lens for an optical viewfinder is disposed on the front center of the housing. In this way, since the optical viewfinder is installed in the front center of the housing, the parallax of the image captured by the still camera with respect to the subject viewed by the optical viewfinder is small, and the parallax of the image captured by the optical viewfinder and the video camera is As a result, the single optical viewfinder can serve as a video camera and still camera finder. As a result, the operator can shoot with a video camera while looking at the optical viewfinder, and at the same time, shoot with a still camera during the shutter chance. However, although the parallax of the video camera and still camera with respect to the optical viewfinder is made small in the example of the above publication, the parallax itself cannot be eliminated.

In order to solve such a problem, a still camera integrated video camera having an electronic viewfinder for displaying an image captured by the video camera apart from the optical viewfinder through a liquid crystal display (LCD) has been continuously developed. Such a video camera can perform imaging by a video camera while the operator looks at the electronic viewfinder, and can also perform shooting by a still camera during a shutter chance, so that such parallax does not occur. In the still camera integrated video camera as described above, a zoom lens is used for the still camera and the video camera objective, so that shooting and imaging can be performed while changing the angle of view from wide angle to telephoto. For example, a distant subject can be taken large, and a subject that does not enter the field of view of a standard lens without a zoom function can be photographed and captured without changing the camera position.

However, since the still camera integrated video camera is designed to display only the image captured by the zoom lens of the video camera in the electronic viewfinder, when the zoom ratio of the still camera and the zoom ratio of the video camera are set differently, the operator The angle of view of the still camera could not be known for sure through the electronic viewfinder. As a result, when there is a difference in zoom magnification, the operator has a problem of performing shooting using a still camera without exactly knowing the angle of view of the still camera.

SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and an object of the present invention is to provide a still camera integrated video camera configured so that the angle of view of a still camera can be confirmed by an electronic viewfinder when the video camera is being photographed.

By supplying the to the focus driver 42 for driving, portus control for controlling the position of the lens is performed.

Next, the configuration of the video camera unit 34 will be described.

In the video camera unit 34, an image of a subject is supplied to a video camera signal processing circuit 61 made of a CCD (charge coupled device) image sensor or the like via a zoom lens 11 and an aperture 60, and converted into an electrical signal. . The video camera signal generated by the video camera signal processing circuit 61 is superimposed with the sound around the subject obtained by the microphone 63 by the signal processing circuit 62, and the magnetic head 65 installed in the rotating drum 64. Is recorded on the magnetic tape 33 by the 8 mm video method, the VHS method, or the like. The zoom driver 66 moves the corresponding lens of the zoom lens 11 according to the zoom driving signal supplied from the video camera zoom control circuit 68. The video camera zoom control circuit 68 detects a zoom ratio of the zoom lens 11, generates a zoom driving signal according to the zoom information supplied from the control circuit 44, and supplies the zoom driving signal to the zoom driver 66. The focus driver 67 performs the focus control by moving the corresponding lens of the zoom lens 11 according to the focus control signal (AF signal) supplied from the control circuit 44. The control circuit 44 generates zoom information corresponding to the zoom ratio set by the operation of the zoom switch 15, and supplies the generated zoom information to the video camera zoom control circuit 68.

The aperture driver 69 controls the amount of opening of the aperture 60 according to the aperture control signal (AE signal) supplied from the control circuit 44 to control the amount of light incident on the CCD image sensor. The control circuit 44 generates an aperture control signal according to the brightness information of the subject supplied from the measuring device 26, and supplies the aperture control signal to the aperture driver 69, and the aperture driver 79 processes the video camera signal according to the aperture control signal. It exists in the circuit 61 and controls the quantity of light supplied to the CCD image sensor which converts light into an electrical signal.

On the other hand, the video camera signal converted into an electrical signal by the video camera signal processing circuit 61 is supplied to the character insertion circuit 71 via the selection circuit 70. The character insertion circuit 71 creates an insertion character in accordance with the information from the control circuit 44 and simultaneously inserts the created insertion character into an image displayed through the electronic viewfinder 12. The character insertion circuit 71 of the present embodiment can display the zoom ratio of the zoom lenses 11 and 22 and the angle of view of the still camera on a part of the screen of the electronic viewfinder 12. In addition to the zoom factor, the character insertion circuit 71 makes it possible to display information of the VTR mode such as date, time, play, record, and the like through the electronic viewfinder 12.

The control circuit 44 includes an imaging switch 13, a video camera power switch 14, a video camera zoom switch 15, a shutter port 17, a still camera power switch 18, a still camera zoom switch 19, and Various operation tools 16 are connected. The control circuit 44 performs the zoom control processing described later, and in addition, controls the operations of the video camera unit 34 and the still camera unit 32 in response to the operation of each switch.

Most imaging devices used in the video camera 34 are CCD image sensors, and the size is currently 1/3 inch and 1/4 inch. And the film 31 used for the still camera part 32 is 35 mm mainly. Therefore, it is possible to make the lens diameter smaller toward the video camera section 34 than the still camera section 32. For example, when the zoom lens capable of 2x zoom of 35 to 70 mm is attached to the still camera part 32, the video camera part 34 can be equipped with a zoom lens of 3 to zoom of 35 to 105 mm. In this case, the still camera unit 32 may match the angle of view of the video camera unit 34, but the zoom magnifications of the still camera unit 32 and the video camera unit 34 coincide with each other. 35 to 70 mm) and their zoom ratios differ from each other (70 to 105 mm).

In addition, the control circuit 44 stores programs for still shooting during video shooting. These programs are based on the zoom ratio between the zoom ratio detected by the still camera zoom control circuit 43 and the zoom ratio detected by the video camera zoom control circuit 68, and the still camera unit 32 in the electronic viewfinder 12. Still image display program for displaying a small screen of the image corresponding to the angle of view taken by the zoom lens 22, zoom ratio of the still camera unit 32 and the zoom ratio of the video camera unit 34 to the electronic viewfinder ( 12), and a zoom magnification adjusting program for adjusting the zoom magnification of the video camera unit 34 to be equal to the zoom magnification of the still camera unit 32 when shooting with only the still camera 32.

The signal processing circuit 62 demodulates the reproduced picture signal and the audio signal read out from the magnetic tape 33 by the magnetic head 65 in the reproduction mode, and outputs an external device such as a monitor through the output terminal Tout. Will output At this time, the electronic viewfinder 12 displays the reproduced image by the reproduced image signal supplied from the signal processing circuit 62.

Reference numeral 72 denotes an image processing circuit, which corresponds to a zoom ratio of the zoom lens 22 from an image signal converted by the video camera signal processing circuit 61, that is, an image signal picked up by the video camera unit 34. While generating a corrected image to eliminate the parallax due to the separation distance between the zoom lens 11 and the zoom lens 22. As a result, when both the imaging of the video camera unit 34 and the shooting of the still camera unit 32 are performed, the electronic viewfinder 12 displays the image captured by the video camera unit 34 on the full screen. At the same time, the image having the same angle of view as the still image captured by the still camera unit 32 and whose parallax between the zoom lenses 11 and 22 is corrected is displayed on a small screen. Therefore, the operator who views the electronic viewfinder 12 can simultaneously check the angle of view taken by the video camera 34 and the angle of view taken by the still camera 32.

Reference numeral 73 denotes a margin part creation circuit, which generates image information of the insufficient part when the image information for the small screen inserted into the electronic viewfinder 12 is insufficient. When the zoom magnification of the still camera zoom lens 22 is set to a wider angle than the zoom magnification of the video camera zoom lens 11, the small picture is captured by a portion which is taken by the video camera 34 and deviates from the field of view of the corrected image. There is a lack of image information. In this case, the margin part creation circuit 73 calculates the size of the margin part which is insufficient based on the zoom ratio difference, and simultaneously generates image information to replace the margin part. As a result, the electronic viewfinder 12 displays image information generated by the margin part creation circuit 73 in the margin part in the small screen which is out of view angle of the zoom lens 11.

The signals generated by the video camera signal processing circuit 61, the image processing circuit 72, and the margin part creation circuit 73 are supplied to the selection circuit 70, respectively, to the instructions from the control circuit 44. Is selected accordingly. The signal selected by the selection circuit 70 is supplied to the electronic viewfinder 12 via the character insertion circuit 71 and displayed as an image on the screen of the electronic viewfinder 12.

3 and 4 show the screen of the electronic viewfinder 12 when both video imaging and still shooting are performed. In the small screen of FIG. 3, the zoom ratio of the video camera zoom lens 11 is the still camera zoom lens 22. ), And the small screen of FIG. 4 shows a case where the zoom factor of the zoom lens 22 of the still camera unit 32 is set to the wide angle side of the zoom lens 11 of the video camera unit 34. have.

When the power switch 14 and the imaging switch 13 of the video camera unit 34 are on, the selection circuit 70 selects the output of the video camera signal processing circuit 61, and the electronic viewfinder 12 has a video. The image picked up by the camera unit 34 is displayed. When the power switch 18 of the still camera unit 32 is operated on during video imaging, the selection circuit 70 selects both outputs of the video camera signal processing circuit 61 and the image processing circuit 72. As a result, as shown in FIG. 3, the electronic viewfinder 12 displays the image A captured by the video camera portion 34, and at the same time, the still camera portion 32 on the upper left of the image A. A digestive image B having the same angle of view as the still image photographed by the above is displayed. At this time, if the zoom ratio of the video camera zoom lens 11 is set to a wider angle than the still camera zoom lens 22, the electronic viewfinder 12 uses only the image signal captured by the video camera unit 34 to adjust the zoom lens 22. An image B having an angle of view corresponding to the zoom ratio can be displayed. When the power switch 18 of the still camera portion 32 is operated on during video imaging, when the zoom ratio of the still camera zoom lens 22 is set to a wider angle than the video camera zoom lens 11, the selection circuit 70 The outputs of the video camera signal processing circuit 61, the image processing circuit 72, and the margin part creation circuit 73 are selected. As a result, as shown in FIG. 4, the electronic viewfinder 12 displays the image A captured by the video camera unit 34, and at the top left of the image A, the still camera zoom lens 22 The digestive image (B) corresponding to the angle of view of) and the margin part (C) surrounding the periphery of the digestive image (B) are indicated. The electronic viewfinder 12 also displays the zoom ratio of the video camera unit 34 and the zoom ratio of the still camera unit 32, as shown in FIGS. Therefore, the operator can check the zoom ratio of the video camera unit 34 and the zoom ratio of the still camera unit 32 while looking at the electronic viewfinder 12.

Next, the processing executed by the control circuit 44 will be described with reference to the flowchart of FIG. 5.

In step S1, it is checked whether the power switch 14 of the video camera unit 34 is on. If the power switch 14 of the video camera section 34 is on in step S1, the flow advances to S2 to check whether the power switch 18 of the still camera section 32 has been operated on. When the power switch 18 of the still camera portion 32 is off, the control circuit 44 returns to step S1 again, and enters the standby state for repeating the processing of S1 and S2. When the power switch 14 of the video camera unit 34 is turned on in step S1, the control circuit 44 reads the zoom ratio VZ of the zoom lens 11 from the video camera zoom control circuit 68 ( Step S3). The image A captured by the zoom lens 11 in the next step S4 is displayed in the electronic viewfinder 12. Therefore, the operator can confirm the image picked up by the video camera unit 34 and its angle of view in the electronic viewfinder 12. At this time, when the imaging switch 13 of the video camera unit 34 is turned on to enter the recording mode, the image signal output from the video camera unit 34 is recorded on the magnetic tape 33 by the magnetic head 65. do. The zoom ratio VZ of the video camera unit 34 is displayed on the screen of the electronic viewfinder 12.

In the next step S5, it is checked whether the power switch 18 of the still camera unit 32 has been operated on. If the power switch 18 of the still camera portion 32 is turned off during video shooting, step S6 is performed to check whether the power switch 14 of the video camera portion 34 has been turned off. When the power switch 14 of the video camera unit 34 is on in step S6, the process returns to step S4 and imaging by the video camera unit 34 is continued. On the other hand, when the power switch 14 of the video camera unit 34 is turned off in step S6, the control circuit 44 determines that the operation is finished, and the process proceeds to step S7 to form the electronic viewfinder 12 Erase the image displayed by).

On the other hand, in step S5, when the power switch 18 of the still camera unit 32 is operated on, it is set so that still shooting during video imaging can be performed. Then, the control circuit 44 performs step S8 to read the zoom magnification SZ of the zoom lens 22 from the still camera zoom control circuit 43. In step S9, the zoom magnification VZ of the zoom lens 11 and the zoom magnification SZ of the zoom lens 22 are compared. If the zoom magnification VZ is larger than the zoom magnification SZ, step S10 is performed to generate an image B having the same angle of view as the still image photographed by the zoom lens 22 and whose parallax is corrected. Subsequently, step S11 is performed, and as shown in FIG. 3, the electronic viewfinder 12 displays the image A captured by the zoom lens 11 of the video camera unit 34, and at the same time, the image A In the upper left of the) and the same image angle as the still image taken by the still camera unit 32, the disparity corrected image (B) is displayed. By viewing the image B displayed on the screen of the electronic viewfinder 12, the operator can check the angle of view that can be taken by the still camera unit 32 even during imaging, so that the still picture is not missed. You can shoot. In addition, the electronic viewfinder 12 displays the zoom magnification of the still camera portion 32 in the vicinity of the digestive image B, and also displays the zoom magnification of the video camera portion 34. Therefore, the operator can know the difference in the zoom ratio between the video camera unit 34 and the still camera unit 32 while imaging by using the video camera unit 34. Therefore, even if there is a difference in the size of each image displayed in the electronic viewfinder 12, video imaging and still shooting can be performed without any problem.

When step S12 is performed, it is checked whether the power switch 18 of the still camera unit 32 is operated to be off. In this step S12, when the power switch 18 of the still camera unit 32 is on, the processes of steps S11 and S12 are repeated. On the other hand, in step S12, when the power switch 18 of the still camera unit 32 is operated to be off, the above-described processes of steps S6 and S7 are executed.

On the other hand, in the above-described step S9, when the zoom magnification of the still camera zoom lens 22 is set to the wider angle than the video camera zoom lens 11 (VZ SZ), the control circuit 44 performs step S13 to insert it in the margin portion. Generate image information to be generated. When steps S13 and S11 are performed, as shown in FIG. 4, the electronic viewfinder 12 displays the image A captured by the zoom lens 11 of the video camera unit 34, and at the same time, the image ( On the upper left of A), a digestive image B having an angle of view of the zoom lens 22 of the still camera part 32 is displayed, and a margin portion outside the angle of view of the zoom lens 11 around the digestive image B is displayed. (C) is displayed. Therefore, even when the angle of view of the still camera zoom lens 22 is set to a wider angle than the video camera zoom lens 11, the operator can predict and capture still images captured by the still camera unit 32 through the electronic viewfinder 12. have.

In the above step S2, when the power switch 18 of the still camera unit 32 is operated on, step S14 is performed, and the zoom magnification SZ of the zoom lens 22 is the still camera zoom control circuit 43. Read from Step S15 operates the zoom lens 11 such that the zoom magnification VZ of the video camera zoom lens 11 matches the zoom magnification SZ of the still camera zoom lens 22. The next step S16 has the same angle of view as the image photographed by the zoom lens 22 of the still camera unit 32 on the screen of the electronic viewfinder 12 and is corrected so that there is no parallax of the zoom lens 22. The image from 72 is displayed. In this case, the electronic viewfinder 12 becomes a dedicated finder of the still camera unit 32, and furthermore, since the entire screen can be used as a finder, the subject can be easily seen and photographing can be easily performed. As a result, still pictures can be taken while looking at the electronic viewfinder 12 even at a time other than video shooting. In addition, the zoom ratio of the still camera unit 32 is displayed on the screen of the electronic viewfinder 12.

In step S17, it is checked whether or not the power switch 18 of the still camera unit 32 has been operated off. The electronic viewfinder 12 displays a parallax corrected image with an angle of view of the image taken by the zoom lens 22 of the still camera portion 32 until the power switch 18 is operated to the off position. If the power switch 18 is operated to be OFF, the process proceeds to step S7 described above and the image of the electronic viewfinder 12 is deleted.

As described above, the electronic viewfinder 12 has the same angle of view and parallax correction as the still image captured by the still camera portion 32 of the image A captured by the zoom lens 11 of the video camera portion 34. Since the image B is displayed, shooting can be performed while looking at the electronic viewfinder 12 even when only still shooting is performed. Therefore, still pictures can be taken without missing the shutter chance by the still camera unit 32.

In the above embodiment, the electronic viewfinder 12 is configured to be provided on the rear surface of the video camera body 10. However, the present invention is not limited thereto, and the electronic viewfinder 12 is provided in another position. Of course it can be applied. In the above embodiment, the image A captured by the zoom lens 11 of the video camera unit 34 is displayed on the screen of the electronic viewfinder 12, and the still image is displayed on the upper left of the image A. Although the image B corresponding to the angle of view of the zoom lens 22 of the camera unit 32 is displayed, the present invention is not limited to this, but the image B is displayed at different positions (upper right, lower left and right of the screen). Mark on the bottom).

As described above, the present invention eliminates the parallax between the image photographed by the still camera unit and the image photographed by the video camera unit, and displays a video image having the same angle of view as the image photographed by the still camera unit. Is generated using the image picked up and displayed through the electronic viewfinder.
