The selection means for selecting one of the items and the single dial means for instructing the amount of setting or adjusting the selected item are provided, and the amount of setting or adjusting the item selected by the selecting means is set. The input is made by a single dial means.

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an example of a VTR integrated camera device to which the present invention is applied.

In FIG. 1, image light 1 from a subject (not shown) is supplied to an image pickup section 3 through a lens system 2. Here, the lens system 2 is provided with an iris 4. The image pickup unit 3 includes, for example, a CCD for each frame.
A so-called electronic shutter means is provided which can control the charge storage time of the image pickup device. The video signal from the image pickup unit 3 is supplied to the A / D conversion circuit 6 through the amplifier 5, and the digitized video signal is supplied to the digital signal processing circuit 7.

The audio signal picked up by the microphone 8 is supplied to the A / D conversion circuit 10 through the amplifier 9, and the digitized audio signal is supplied to the digital signal processing circuit 7. Then, these digitized video signal and audio signal are combined by the digital signal processing circuit 7 in an arbitrary format, and the combined signal is generated by the VTR unit 1.
1 for digital recording.

In this apparatus, the set values of the iris 4 and the electronic shutter means of the image pickup section 3 are set by the system control circuit 12 of the photographing and recording system. The recording level of the audio signal is adjusted by controlling the gain of the amplifier 9, for example, and the gain of the amplifier 9 is adjusted by the system control circuit 12 of the photographing and recording system. In this way, for example, the iris and shutter speed at the time of shooting and the recording level are adjusted.

Further, a changeover switch 13 for selecting a power-off state, an automatic setting state and a manual setting state.
Is provided, and the signal from the switch 13 is supplied to the system control circuit 12.

An AE selection switch 14 for selecting a mode for setting the iris and the shutter speed in relation to each other, a shutter selection switch 15 for selecting a mode for independently setting the shutter speed, and a mode for adjusting the recording level are provided. A volume selection switch 16 for selection is provided, and signals from these push switches 14 to 16 are supplied to the system control circuit 12.

Further, dial means 17 for instructing the amount to be set or adjusted is provided, and a signal from the dial means 17 is supplied to the system control circuit 12. A display signal indicating the operating state of these switches 13, 14 to 16 and the dial means 17 is supplied from the system control circuit 12 to the display 18.

That is, FIG. 2 shows a VTR to which the present invention is applied.
FIG. 3 is an external view for explaining a main part of the integrated camera device, which is viewed from an oblique rear side of the device.
In this figure, a lens system 2 and a microphone 8 are provided on the front side of the apparatus, and an image pickup unit 3 (not shown) is provided behind the lens system 2. The video signal from the image pickup section 3 and the audio signal from the microphone 8 are recorded in the VTR 11 including the cassette housing section.

Further, in FIG. 2, the above-mentioned switches 13, 14 to 16, the dial means 17 and the display 18 are provided at the rear part of the device. By operating these switches 13, 14 to 16 and the dial means 17, a plurality of photographing conditions of the camera system are set and the recording level of the audio signal is adjusted.

Therefore, these switches 13, 14 are further added.
16 and the setting and adjustment by operating the dial means 17 are performed as described below.

First, when the automatic setting state is selected by the switch 13, all setting and adjustment are automatically performed in the system control circuit 12.

Next, when the manual setting state is selected by the switch 13, the switches 14 to 16 are enabled. When, for example, the AE selection switch 14 is operated, the system control circuit 12 performs a process of toggle-selecting automatic, iris priority, and shutter priority as shown in FIG.

Further, for example, the dial means 17 is activated in a state where the iris priority is selected. By operating the dial means 17, the system control circuit 12 forms a signal for arbitrarily setting the iris 4 and further a signal for setting a shutter speed corresponding to the set iris value.

Further, for example, the dial means 17 is activated in the state where the shutter priority is selected. When the dial means 17 is operated, the system control circuit 12 forms a signal for arbitrarily setting the shutter speed of the image pickup unit 3, and a signal for setting an iris value corresponding to the set shutter speed is generated. It is formed.

When the manual setting state is further selected by the switch 13 and the shutter selection switch 15 is operated, for example, the system control circuit 12 displays the automatic mode, the hold mode, and the 1/100 (as shown in FIG. 4). A process of toggle-selecting 120) seconds and 1/1000 seconds is performed. Here, for example, when hold is selected, the shutter speed set in the automatic state immediately before that is held.

Also, the dial means 17 is activated with 1/100 (120) seconds selected. By operating the dial means 17, the shutter speed of the image pickup unit 3 is changed by the system control circuit 12.
A signal that is arbitrarily set around 1/100 (120) seconds is formed. If the device is NTSC system, 1/1
The setting is performed mainly for 00 seconds, and 1 for PAL system.
The setting is performed centering on / 120 seconds.

Further, the dial means 17 is activated with 1/1000 seconds selected. By operating the dial means 17, the system control circuit 12 changes the shutter speed of the image pickup unit 3 to 1/10.
A signal that is arbitrarily set around 00 seconds is formed.

When the manual setting state is selected by the switch 13 and, for example, the volume selection switch 16 is operated,
In the system control circuit 12, for example, as shown in FIG.
A process of toggle-selecting between automatic and manual is performed.
Then, for example, with the manual mode selected, the dial means 17
Is activated and the dial means 17 is operated, so that the system control circuit 12 operates, for example, the amplifier 9
A signal is formed which controls the gain of the.

Therefore, in this apparatus, it is not easy to provide a setting means and an adjusting means for taking a picture with a better image quality or recording a clear voice in the conventional apparatus. A selection means for selecting an item or one of the recording levels and a single dial means for instructing the amount of setting or adjusting the selected item are provided, and the item selected by the selecting means is set or adjusted. By inputting the operation amount with a single dial means, it is possible to provide a plurality of setting means and adjusting means with a simple configuration.

Further, in the above-mentioned device, the display according to the amount set or adjusted by the dial means 17 is performed on the display 18, whereby the setting or adjustment by the dial means 17 can be performed very well.

In the above apparatus, the items to be set or adjusted are not limited to the above-mentioned iris, shutter speed and recording level, but the gain and brightness of the video signal,
Settings or adjustments such as white balance may be included. The dial means 17 may also be used to select these items.

[0029]

As described above, according to the present invention, it is not easy to provide the setting means and the adjusting means for taking a picture with a better image quality or recording a clear voice in the conventional apparatus. A selection means for selecting one of a plurality of items or one of the recording levels and a single dial means for instructing an amount to set or adjust the selected item are provided, and the item selected by the selection means is selected. By inputting the amount to be set or adjusted by a single dial means, it becomes possible to provide a plurality of setting means and adjusting means with a simple configuration.

Therefore, according to the present invention, it is possible to reduce the number of switches, dial means, etc. provided in the apparatus, simplify the structure, and reduce the manufacturing cost. Further, since the operation method is unified, the operability can be improved.
