DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing assisting device for photographing when a subject blocks a transmitting device and a receiving device facing each other.

[0002]

2. Description of the Related Art Conventionally, this kind of photographing assisting device is composed of a transmitting device for emitting a specific signal, and a receiving device for receiving the signal and transmitting a control signal to a camera according to the type of the signal. When a signal is interrupted between the transmitting device and the receiving device, the camera has only the function of releasing only one frame of the camera. Also, when taking such a photograph, the delay release mode was meaningless.

[0003]

However, the conventional photographing assisting device has only the function of releasing only one frame even if the subject blocks the space between the transmitting device and the receiving device. When shooting such things, there was a risk of missing a photo opportunity. Furthermore, while the subject blocks the space between the transmitting device and the receiving device,
If the release signal is continuously output, the release signal is continuously output due to an unexpected phenomenon such as a shift of the optical axis between the transmitting device and the receiving device, and the film may be lost. . In addition, such photographing requires an operation of aligning the optical axis between the transmitting device and the receiving device, but in order to achieve this, a dedicated mode switching position is required.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a photographing assisting device capable of preventing a camera from being unnecessarily released due to a mode change. To provide.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, when the mode of the transmitting apparatus is the continuous release mode, the signal of the receiving apparatus is interrupted. Sometimes, a finite time release signal is output. Also, in order to provide a function for aligning the optical axis between the transmitting device and the receiving device, a test operation is performed when the mode of the transmitting device is the delay release mode.

[0006]

According to the present invention, the operation of the camera is a single release mode, a continuous release mode for a finite time, and a release output for optical axis alignment when an object crosses between the transmitting device and the receiving device facing each other. Test mode can be selected.

[0014]

[Table 1]

IC is a continuous release signal in an interrupt mode. IT is a test signal in an interrupt mode. Here, the normal mode is the transmission button SW3
Is a mode for transmitting a signal only when is pressed, and the interrupt mode is a mode for continuously transmitting a signal without pressing the transmission button SW3.

The operation signals of the receiver when these signals are received are: NS: single release signal to be output to the camera NC: release signal to be output to the camera ND: output to the camera after a predetermined time Single release signal NR: Signal to turn off the release signal being output to the camera IS: Single release signal to be output to the camera when the signal is interrupted IC: Release to be output to the camera for a predetermined time when the signal is interrupted Signal IT: A signal for turning on the monitor LED when the signal is interrupted.

FIG. 4 shows a flowchart of the transmission apparatus 10 according to the present invention. In FIG. 5, when the mode switch SW1 serving as a power switch is turned on, the operation of the microcomputer MCU1 starts. In step 101, the state of the mode switch SW1 is read. Here, the state of the mode switch SW1 is "NORM".
If it is located at the position, the process proceeds to step 102. Step 1
At 02, it is determined whether or not the transmission button SW3 has changed from the on state to the off state.

In step 104, it is determined whether or not the transmission button SW3 has been turned on. If the transmission button SW3 has been turned on, the flow advances to step 105 to determine the state of the mode switch SW2. If the mode switch SW2 is in the "S" position, step 106
To transmit a single release signal (NS), and if the mode switch SW2 is not at the position of "S", step 1
Proceed to 07. In step 107, the state of the mode switch SW2 is determined. If the mode switch SW2 is in the "C" position, a release signal (NC) is transmitted in step 108. If the mode switch SW2 is not in the "C" position, the process proceeds to step 109, where the delay release signal (N -D). Send button S in step 102
If it is detected that W3 has changed from the on-state to the off-state, a continuous release reset signal (NR) is transmitted in step 103.

If the mode switch SW1 is not at the "NORM" position in step 101, that is, if it is at the "INT" position, the routine proceeds to step 110. If the mode switch SW2 is at the "S" position in step 110, the process proceeds to step 111, where a signal (IS) is transmitted. Step 1
If the mode switch SW2 is at a position other than the "S" position at 10, the process proceeds to step 112. In step 112, it is determined whether or not the mode switch SW2 is at the "C" position. If the mode switch SW2 is at the "C" position, the process proceeds to step 113, where the signal (I-C)
Send If the mode switch SW2 is not at the "C" position in step 112, the process proceeds to step 114 to transmit a signal (IT). Signal (IS), signal (I-
C), after the transmission of the signal (IT), the process returns to step 101, so that the signal determined by the mode switch SW2 continues to be transmitted as long as the mode switch SW1 is at the position of "INT".

FIG. 5 shows a flowchart of the receiving apparatus 20 according to the present invention. In FIG. 2, when the operation of the receiving device 20 starts, a signal transmitted from the transmitting device 10 is received in step 201. If no signal comes here, this operation is repeated. Upon receiving the signal, the type is determined in step 202. If this signal is a signal at the “NORM” position, step 203
Proceed to. If this signal is a signal (NR) in step 203, the process proceeds to step 204, where the output of the release signal is turned off. If the signal is not a signal (N-R) in step 203, the process proceeds to step 205, and it is determined whether the signal is (N-S). If the signal is (N-S), step 20
Proceed to 6 to output a single release signal to camera C.

If the signal is not a signal (NS) at step 205, the process proceeds to step 207, where it is determined whether the signal is (NC). If it is a signal (NC), step 20
Proceed to 8 to output a release signal to the camera C.
If the signal is not the signal (NC) in step 207, it is determined that the delay release signal (ND) is received, and
Go to 9. In step 209, after waiting for a predetermined time, the process proceeds to step 210, where a single release signal is output to the camera C. Therefore, the camera C is released with a certain time delay from the reception of the signal (ND).

After the processing of steps 206, 208 and 210 is completed, the process returns to step 201 and waits for the next signal. Here, when the transmission device 10 transmits the signal (IC), the release signal remains output to the camera C in step 208, but when the transmission button SW3 of the transmission device 10 is turned off, the signal (N -R) is received, where step 2
Since the release signal output to the camera C is turned off at 04, the release operation of the camera C ends.

In step 202, the received signal is "NORM"
If not, it is determined that the position is "INT" and the process proceeds to step 211. At step 211, a timer is set, and at step 212, timer interruption is permitted. This is used to determine whether a signal continuously transmitted at a certain time interval is interrupted. That is, by setting a time longer than the time interval at which the signal comes in step 211, the timer is constantly updated while the signal is being received, so that no timer interrupt occurs, but the signal is interrupted. This does not update the timer, which causes a timer interrupt. After permitting the timer interrupt in step 212, the process returns to step 201 to receive the next signal.

When a timer interrupt occurs due to the interruption of the signal as described above, the flow proceeds to step 213. In step 214, it is determined whether the signal received so far is the signal (IS), and if it is the signal (IS), the process proceeds to step 215 to output a single release signal to the camera C. In step 214, it is determined whether the signal received so far is the signal (IC). If the signal is the signal (IC), the flow advances to step 217 to output a release signal to the camera C. Then, a predetermined time elapses in step 218, and thereafter, in step 219
Turns off the output of the release signal to the camera C.

Therefore, when the signal (IC) is interrupted, a release signal is output to the camera C only for a predetermined time. Therefore, by setting the camera C in the continuous release state, a plurality of frames can be photographed. It becomes possible. Step 216
If the signal received so far is not the signal (IC), it is determined that the signal is the signal (IT), and
Go to 20. In step 220, a test operation for confirming that the test signal, specifically, the light-emitting diode LED of FIG. At this time, the release signal is not output.
After the processing of step 215, step 219, and step 220 is completed, the process returns to step 201 to receive the next signal.

[0026]

As described above, according to the present invention,
An unmanned shooting mode (interrupt mode) in which the shutter of the camera can be released when a subject crosses between a transmitting device and a receiving device facing each other, and shooting in multiple camera control modes by pressing operation buttons In a photographing auxiliary device capable of selecting a possible remote photographing mode (normal mode), optimal camera control can be performed for photographing in the normal mode and the interrupt mode by a combination of two mode switches of the transmitting device. That is, when the "S" position is selected by another mode switch when the normal mode is selected, a single release mode in which one frame can be photographed each time the transmission button is pressed, and when the "C" position is selected, the transmission button is selected. When the continuous release mode in which continuous shooting can be performed while the button is pressed is selected, and a position of "D / T" is selected, a delay release mode in which the release is performed a predetermined time after the transmission button is pressed is set. When the "S" position is selected by another mode switch when the interrupt mode is selected, a single release mode in which one frame can be photographed when the signal is interrupted, and when the "C" position is selected, the signal is output. When a continuous release mode in which shooting can be performed continuously for a predetermined time when the signal is interrupted, and a position of "D / T" is selected, a test mode in which a monitor LED is notified when a signal is interrupted is set. That is, the release signal is output only for a predetermined time when the signal is interrupted when the position “C” is selected, so that the release signal is output while the signal is interrupted in the same manner as in the normal mode. In this case, it is possible to prevent a problem that the film is lost due to continuous release due to an unexpected accident such as a shift of the optical axis between the transmitting device and the receiving device. Also, when the “D / T” position is selected, a shutter chance is provided during unmanned shooting of an animal or the like, even if the shutter is released a predetermined time after the signal is interrupted, as in the normal mode. Missing, meaningless operation. Actually, in the interrupt mode, it is necessary to adjust the optical axis between the transmitting device and the receiving device, and thus it is necessary to adjust the optical axis in advance. in this case,
The receiver turns on the monitor LED without releasing the output simply by switching the mode switch of the transmitter to the mode of the "D / T" position, so that the film is not wasted during the adjustment. .
