Abstract

PURPOSE:To set a release control function if a shutter speed is inappropriate and to prevent trouble by connecting the title device to a camera main body and appropriately performing an interval timer function and a long time exposing function. CONSTITUTION:The controller is provided with the camera release control function of a data bag device 101, a setting panel part 103 capable of setting imprinted data, a liquid crystal data display part 104 displaying data set by the setting panel part 103, etc. At the time of a valve, setting the interval timer function is inhibited, whereas on any occasions apart from the valve, setting the long time exposing function is inhibited. In addition, in order to compositely set the interval timer function and the long time exposing function, the interval timer function can be set even at the time of the valve as long as the long time exposing function is set. Thus, such trouble can be eliminated that if a shutter speed is inappropriate, the release control function cannot be set, nor determined.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a camera control device that can be connected to a camera that can set an interval timer function and a long-time function, and can control the release of the camera.

[Prior Art] Some conventional camera control devices of this type allow a long exposure function to be set by setting the camera body to a shank speed other than the bulb speed.

There was also one that allowed you to set the camera body to a bulb and set an interval timer function.

[Problems to be Solved by the Invention] However, in a camera control device that allows the long exposure function to be set when the shutter speed of the camera body is set to a speed other than the bulb, when the long exposure function is activated, the set exposure time There was a problem in that the snapshot was taken only during the period. On the other hand, in a device in which the interval timer function can be set when the shutter speed of the camera body is bulb, there is a problem that the shutter speed becomes unstable when the interval timer function is released when the interval timer function is activated. Furthermore, in an apparatus capable of taking a plurality of images at each interval time of the interval timer function, a problem arises in that the interval timer function stops.

The present invention aims to solve the above problems.

[Means for solving problems]

In the present invention, in order to solve the above problems, when using a valve,
The interval timer function cannot be set, and the long exposure function cannot be set when using anything other than bulb, and the long exposure function can be set to enable combined setting of the interval timer function and long exposure function. The interval timer function can now be set on the valve as well.

[Function] In the present invention, in a camera control device capable of controlling the release of a camera that can be connected to a camera body and set an interval timer function and a long exposure function, when the shutter speed of the camera body is bulb, the interval timer function is activated. When the shutter speed of the camera body is set to a value other than bulb, the long exposure function cannot be set, and the long exposure function is set to enable combined setting of the interval timer function and long exposure function. If the shutter speed of the camera body is inappropriate, the interval timer function can now be set even if the shutter speed of the camera body is inappropriate, so there will be no inconvenience caused by not being able to set the camera's release control function. .

1, and the rDATAJ character 213 indicating the data imprinting mode lights up. Last time, when I exited the data imprint mode, the year, month, and day were displayed, so the display was 511.
The year, month, and day will be displayed. Note that the "4" symbol 405 indicating that the long exposure function has been set is displayed in the display 511.
It also lights up to indicate that the long exposure function has been set. When the function selection button 131 is pressed when the display 511 is displayed, the oval symbol 262 indicating the interval timer mode lights up, and the interval time display 512 is displayed.

Also in the display 512, the "4" symbol 405 indicating that the long exposure function is set is lit, indicating that the long exposure function is set. If the function selection button 131 is pressed when the display 511 is displayed, the display returns to the display 401. Also, if you press the set/reset button 136 when the display 512 is displayed,
Even if the shutter speed of the camera body is a bulb, the shank speed is determined by the exposure time of the long exposure function, so the interval timer function is set and the display 513 appears. Then, a "(" symbol 305 indicating that the interval timer function has been set is lit, indicating that the interval timer function has been set. Therefore, the display 513 indicates that the interval timer function has been set. The "(" symbol 305 indicating that the long exposure function has been set) and the "4" symbol 405 indicating that the long exposure function has been set are lit, indicating that the interval timer function and the long exposure function have been set in combination.

As explained in Figures 5 (A) and (B) above, after setting the interval timer function, the long exposure function cannot be set because the shutter speed of the camera body is not a valve, so even if it is set, it will cause inconvenience. After setting the long exposure function, even if the shutter speed of the camera body is bulb, the shank speed is determined by the exposure time of the long exposure function, so the interval timer function can be set.

Next, the display when the interval timer function and long exposure function are set in combination will be explained using the sixth part.

When the function selection button 131 is pressed when the interval time display 513 is lit with the oval symbol 262 indicating the interval timer mode in which the interval timer function and long exposure function are combined, the oval symbol indicating the long exposure mode will be displayed. The exposure time display 601 292 lights up.

Even when the display 601 is displayed, the "(" symbol 305 indicating that the interval timer function has been set and the "4" symbol 405 indicating that the long exposure function has been set are lit, indicating that the interval timer function and long exposure function have been set. This indicates that the exposure function and the exposure function have been set in combination. When the function selection button 131 is pressed when the display 601 is displayed, the display 602 appears and the rDATAJ character 213 indicating the data imprinting mode lights up. Last time, the data imprinting mode was set. Since the year, month, and day were displayed when the timer was removed, the display 602 displays the year, month, and day.The display 602 also does not indicate that the interval timer function has been set. 4” symbol 305 and “(” symbol 405 indicating that the long exposure function has been set.
lights up, indicating that the interval timer function and long exposure function have been combined. Display 602
If the function selection button 131 is pressed at this time, the screen returns to the display 513.

Next, when the interval timer function and long exposure function are combined, press the set/reset button 136.
The case where is pressed will be explained using FIGS. 7(A) and (B).

FIG. 7(A) is an explanatory diagram when the interval timer function and long exposure function are set in combination and the set/resen L-button 136 is pressed in the interval timer mode. If you press the Set/Receive I button 136 when the interval time display 513 is lit with the oval symbol 262 indicating the interval timer mode in which the interval timer function and long exposure function are combined, the interval timer function setting is canceled. A display 512 is displayed.

In the display 512, since the setting of the interval timer function has been canceled, the "4" symbol 305 indicating that the interval timer function has been set is turned off. Note that the long exposure function remains set, so the "(" symbol 405 indicating that the long exposure function has been set remains lit.) If you press the set/reset button 136 when the display 512 is displayed, the interval The timer function is set and the screen returns to display 513. In display 513, the "(" symbol 305 indicating that the interval timer function has been set is lit. Therefore, the interval timer function and long exposure function are once again set in combination. Displays the combined settings for these functions.

Figure 7 (B) shows that the interval timer function and long exposure function are combined and set in long exposure mode.
FIG. 6 is an explanatory diagram when the reset button 136 is pressed. When the exposure time display 601 is lit with an oval symbol 292 indicating a long exposure mode in which the interval timer function and long exposure function are combined, the set/reset button 1 is pressed.
When 36 is pressed, the combined setting of the interval timer function and long exposure function is canceled, and the setting of both functions is canceled, resulting in display 291. In other words, if the long exposure function setting is canceled, if the shutter speed of the camera body is set to bulb, the shutter speed due to the interval timer function will become unstable, which is inconvenient, so it is recommended to cancel the interval timer function setting at the same time. It has become. Therefore, in the display 291, both the "4" symbol 305 indicating that the interval timer function has been set and the "4" symbol 405 indicating that the long exposure function has been set are turned off.

Long exposure mode in which the oval symbol 292 indicating long exposure mode lights up When the set/reset HO 136 is pressed when the exposure time display 291 is displayed, the "4" symbol 405 indicating that the long exposure function has been set lights up. Exposure time display 4
01, and only the long exposure function is set. Display 4
If the set/reset button 136 is pressed at 01, the display returns to 291 and the long exposure function is canceled.

In other words, in FIG. 7(B), when the interval timer function and long exposure function are combined and you try to cancel the long exposure function, the interval timer function is also canceled at the same time, and the shutter speed of the camera body is changed. After that, even if the long exposure function is set, the interval timer function will not be set at the same time.
