Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention integrally comprises a silver halide camera and a video camera for recording a moving image picked up by an image pickup device or the like on a recording medium such as a magnetic tape, so that one person can take a picture. The present invention relates to a device that enables a person to shoot both at the same time, and more particularly to a shooting device that prevents the stroboscopic shooting of a silver halide camera from adversely affecting the recording of a video camera.

[0002]

2. Description of the Related Art Conventionally, a still image is recorded with a silver salt film or the like while shooting with a video camera for recording a moving image on a recording medium such as a magnetic tape for an event such as an athletic meet or an arts and crafts event. Some people want to shoot with a silver salt camera. In addition, there are some voices that it is troublesome to carry both a video camera and a silver salt camera separately when traveling, and in response, a video camera and a silver salt camera integrated silver salt camera integrated video camera Is being considered.

A silver salt film, which is a recording medium of a silver salt camera, may have lower sensitivity than an image pickup device such as a CCD usually used in a video camera, and it is necessary to provide a stroboscopic light emitting portion as an auxiliary light source. There is. However, if the flash firing part emits light while recording with the video camera part,
Since a large amount of light is emitted instantaneously due to this light emission, the iris of the video camera unit narrows down the amount of light, and soon overexposure occurs. Also, the iris of the video camera unit is irradiated from the strobe light emission unit, and the aperture operation is delayed for a certain time in order to properly adjust the exposure.
On the contrary, several screens after the screen recorded due to overexposure are darkened, resulting in underexposure.

A proposal to solve this problem is disclosed in "Video camera with still camera" in Japanese Patent Laid-Open No. 63-166374. In this case, the video camera unit is equipped with a DC power source corresponding to the gray level of the reproduced image or a pseudo signal generation unit such as a RAM for storing the image of the immediately preceding field, and when the strobe light emission unit emits light, The signal for one field including is replaced by a DC signal from the pseudo signal section or a pseudo signal such as the previous field signal so that the stroboscopic light emission is not recorded on the screen.

USP (USA) 5189463
JP-A No. 2003-242242 proposes a method in which a photographic image is created by intermittently reading an image signal, and a light emission pattern emitted in the interval is not recorded in a camera. in this case,
When shooting and recording with a video camera, etc., the camera emits laser light etc. only during the intermittent reading of the signal that creates the image, and the photographer can confirm the laser light, but that light is not recorded as an image To do so.

[0006]

However, in the above-mentioned conventional example, in the former case, the pseudo signal is replaced by a single gray color signal for one field, which is not preferable for the continuity of the screen. In addition, if the previous image is stored in the RAM or the like and the previous image is recorded again only when the strobe light emitting unit emits light,
Since the same image continues for 2 fields (1/30 seconds), the moving image may be unnatural, and it is preferable that a certain time period when the strobe fires is lost temporally. There is a problem of not having.

Next, in the latter case, considering the application to the stroboscopic light emission of the silver halide camera, the stroboscopic light emission timing is recorded during one field recording of the video camera (about 16.6 m).
It is necessary to use the blanking time of (s) (about 1.42 ms) and synchronize with it so as to obtain an image in which the stroboscopic light emission is virtually unrecorded. However, when considering the control of the silver halide camera in a video camera with an integrated silver halide camera, the flash emission time is about 1 ms, the error in the time when the shutter of the silver halide camera opens, and the flash emission after opening. There is almost no margin in the total blanking time (1.42 ms) of the mechanical error of the silver halide camera, such as the error in the timing of turning on the X contact, which is the synchronization signal of the above. There is a problem that it is practically difficult when considering variations and the like.

Next, the operation will be described with reference to FIGS.

FIG. 10 shows the sequence of the video signal controlled by the video control system 38 and the silver halide camera controlled by the camera control system 39. The shutter is released by the user to release the silver salt camera. When the button 18 is pressed, the SW2 signal 50 is generated. The camera control system 39 starts control of the silver halide camera unit by inputting SW2.
First, the battery check (BC) 51 determines whether or not photographing is possible by energizing, for example, a film winding motor of the silver salt camera unit. If it is possible to shoot, then the diaphragm drive motor (EMD) 52 is energized for a predetermined time to narrow down the diaphragm 28a.

A magnet for the front curtain of the shutter 25 (MG3
-1) 53 and trailing curtain magnet (MG3-2) 54
Is the shutter curtain 25 when the power to each magnet is cut off.
C is running. Each magnet 53, 5
4 is controlled by the camera control system 39 so that the energization is cut off after the diaphragm drive motor 52 has narrowed down the diaphragm 28a and after a lapse of a predetermined waiting time for stabilizing the mechanism. In the traveling state 55 of the front curtain and the rear curtain, the solid line in the shaded area represents the front curtain and the broken line in the shaded area represents the rear curtain. Therefore, this represents the amount of exposure of the parallelogram portion surrounded by the solid line and the broken line. Actually, the first and second curtains are each magnet 5
From when the power is turned off to when the vehicle actually travels,
There is a certain time lag, which is 5 ms in this embodiment.

On the other hand, reference numeral 56 indicates a state in which the X contact, which is a trigger for strobe emission, is turned on, and the X contact is the shutter 25.
The mechanism switch provided inside turns it on when the front curtain has completed traveling. Reference numeral 57 shows a state in which a field image is recorded in the video camera unit, and 1 field is 1/60 seconds, of which about 1.4 ms is a blanking time and an image is not recorded.

Next, referring to FIG. 11, the camera control system 3
9 and the shutter control unit 44 opens the shutter 25,
The operations of the image sensor control section 43 and the video control system 38 when the strobe 9 emits light will be described in detail.

Reference numeral 58 represents the light emission state of the strobe by the light intensity. When the strobe 9 emits light, the solid-state image sensor (CC
The output 59 of D) 33 inputs a very large value with respect to the normal level with a slight time delay in strobe emission. Therefore, inconvenient recording such as overexposure is performed. Therefore, in the present embodiment, the image sensor control unit 4
Reference numeral 3 has a peak detection circuit that detects a change in the intensity of light input to the solid-state image sensor 33, detects that the strobe 9 has emitted light, and generates a peak detection signal 60.

On the other hand, the video control system 38 is the solid-state image pickup device 3
The signal from 3 is recorded as a video signal on a medium such as a video tape, and the vertical synchronizing signal 61 is generated as a reference signal for recording. The video image is recorded by recording the information accumulated by the solid-state image pickup device 33 at the time excluding the blanking time based on the vertical synchronizing signal. During recording,
Peak detection signal 6 generated by the image sensor control unit 43
When 0 is input to the video control system 38, the video control system 38
Resets and discards the image information signal accumulated in the time from the vertical synchronization signal 61a of one field to the peak detection signal 60 for the image of one field including the peak detection signal 60. After that, accumulation is started again, and normal accumulation is performed until the accumulation of the field is completed. This state is 62, which means that the image signal in the shaded area is not recorded from the video recording signal.

As described above, in this embodiment, the time of the image signal which is not recorded is determined while directly detecting the strobe light input to the solid-state image pickup device 33. There is no fear of synchronization deviation between the signal and the flash timing of the strobe 9, and the record of the period when the strobe 9 fires can be deleted surely, and the deletion period is not one field but a short time corresponding to strobe flash. There is no loss of the corresponding field, and the reproduced image does not become unsightly.

Next, a second embodiment of the present invention will be described.

FIG. 12 is a partially transparent front view of an image pickup apparatus according to the second embodiment of the present invention.

FIG. 13 is a timing chart of the camera control system and the video control system of the photographing apparatus shown in FIG.

In the second embodiment shown in FIG. 12, the dimming sensor 100 mounted toward the shutter 25 for a silver halide camera.
To use. The dimming sensor 100 measures the light amount of the photographic film 22 when the shutter 25 is open and the photographic film 22 is exposed. If the strobe 9 emits light during the exposure, the photographing lenses 26, 29 and 34 are turned on. When the strobe light that has passed through reaches the photographic film 22 and the photographic film 22 is properly exposed, the light control sensor 100
An exposure completion signal is generated to stop the flash of the strobe 9. In this embodiment, the light control sensor 100 is used to detect the strobe light emission timing. The same components as those of the other first embodiment are designated by the same reference numerals, and duplicated description will be omitted.

The operation will be described below with reference to the drawings. First, when the shutter 25 opens and the front curtain 55 completes traveling,
As indicated by 58 in FIG. 13, the strobe 9 emits light. At this time, the dimming sensor 100 measures the reflected light amount of the photographic film 22 and outputs a predetermined signal 101 when the appropriate exposure amount is obtained by the strobe light, and outputs this output value 101 to the camera control system 39. After outputting, the camera control system 39 stops strobe emission. At this time, the camera control system 39 uses the strobe 9
The timing output 102 is output to the system controller 37 at the same time when the emission of light is stopped.

Here, the vertical synchronizing signal 61 generated by the video control system 38 is also output to the system controller 37,
The system controller 37 resets and discards the accumulated image information signal with respect to the time from the corresponding vertical synchronization signal 61 of the image information signals for one field including the timing output 102 to the timing output 102. The control system 38 is controlled. After that, the accumulation is started again and the accumulation is performed in the same manner as usual until the accumulation of the field is completed, as in the previous embodiment. This is the state of 62 shown in FIG.

As described above, the same effects as in the previous embodiment can be obtained in the second embodiment.

Next, a third embodiment of the present invention will be described.

FIG. 14 is a block diagram of an image pickup apparatus according to the third embodiment of the present invention.

In the third embodiment shown in FIG. 14, the photographing optical systems of the silver salt camera section and the video camera section are separately arranged.

The taking optical system 200 for a video camera has a diaphragm 201 for a video camera and forms an image on the image pickup device 33. On the other hand, the photographing optical system 203 for the silver salt camera has a diaphragm 204 for the silver salt camera and is arranged on the optical axis of the photographic film 22. The same components as those of the other first embodiment are designated by the same reference numerals, and duplicated description will be omitted.

First, when a zoom button (not shown in FIG. 14) is pressed, the zoom controller 41 brings the video camera taking optical system 200 and the silver halide camera taking optical system 203 to appropriate zoom positions. Control. Further, the focus control section 40 also sends the same distance information to both the silver halide camera section and the video camera section, and controls so that the two focus points always match.

Then, when the silver halide camera section is exposed and the camera control system 39 causes the strobe 9 to emit light,
The same processing as in the first embodiment is performed. That is, the solid-state image sensor 33 receives the strobe light, and the image sensor controller 43 generates the peak detection signal 60. When the peak detection signal 60 is input to the video control system 38, the video control system 38, with respect to the image of one field including the peak detection signal 60, the vertical synchronization signal 61a of the one field.
Then, the same processing as in the first embodiment is performed, in which the image information signal accumulated in the time from the peak detection signal 60 to the peak detection signal 60 is reset and discarded.

As described above, in the third embodiment, even if the silver halide camera portion and the video camera portion operate independently of each other, there is no need for complicated system synchronization processing, and light is emitted for the silver halide camera. This makes it possible to prevent the strobe light from being recorded in the video image. The detection method by the light control sensor 100 of the second embodiment can also be applied to the detection of the flash emission timing.

Further, the separate type as in the third embodiment has an advantage that each photographing optical system can be set in an optimum state suitable for the required performance, and the zoom magnification of the silver halide camera section is set to the video camera section. It is most suitable for applications where it is not necessary to make it so high.

Correspondence between Embodiments and Embodiments In the above embodiments, the processing of the image sensor control system 43 that receives the strobe light by the solid-state image sensor 33 to generate the peak detection signal 60 and the amount of reflected light of the camera film 22 are adjusted. The process of the camera control system 39 which measures the light output from the optical sensor 100 and outputs the timing output 102 corresponds to the process of the detecting means of the present invention.

By inputting the peak detection signal 60, the peak detection signal 6 in one field including the peak detection signal 60
The video control system 38 is controlled by the processing of the video control system 38 for discarding image signals up to 0 and the input of the timing output 102 so as to discard the image signals up to the timing output in one field including the timing output 102. The processing of the system controller corresponds to the processing of the deleting means of the present invention.
