DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
1 to 6 is a rear view, flowcharts, and block connection diagram showing a first embodiment of the control panel.
[0013]
In Figure 1, the lock switch 100 is a switch for prohibiting the input of the mode-changing operating member. The main body 10a and the upper cover 10b constitute the outer shape of the camera. The operation members 20a and 20b are dial type operation members. The operation members 21a, 21b, 21c, and 22 are push button type operation members, and are used as means for changing or achieving the mode.
[0014]
Although details of the lock switch 100 will be described later, the lock mode is entered by rotating the lever 100a, and input on the operation members 20a, 20b, 21a, 21b, 21c, and 22 is prohibited. The operation member is not limited to the dial type or push button type described above.
[0015]
FIG. 2 shows a state where the lock switch 100 is OFF. That is, the operation members 20a, 20b, 21a, 21b, 21c, and 22 can be input normally. FIG. 3 shows a state in which the lock switch 100 is in ALL LOCK. That is, all the inputs from the operation members 20a, 20b, 21a, 21b, 21c, and 22 are currently locked. That is, when the main power is turned on, input of all the operation members 20a, 20b, 21a, 21b, 21c, and 22 is prohibited.
[0016]
FIG. 4 shows a state in which the operation members 20a, 20b, 21a, 21b, 21c, and 22 to be locked by the user can be selected. After the main power is turned on, the lever 100a of the lock switch 100 is set to the SET position, the user inputs a desired mode using the operation members 20a, 20b, 21a, 21b, 21c, and 22, and the lever 100a of the lock switch 100 Rotating to match the LOCK position, the mode input at the SET position is locked, and subsequent signal input is prohibited. For example, a dial type such as the operation member 20a in FIG. 1 cannot be rotated, and a push button type such as the operation member 21a cannot be pressed. Since the locked mode is recognized by transmitting an input signal, it is necessary to transmit the signal again even if the desired mode is already set by the initial setting when the power is turned on. In addition, the operation members 20a, 20b, 21a, 21b, 21c, and 22 to which no signal is input in the SET state can be input to change the mode even after the LOCK as in the OFF state. Become. Further, when the LOCK is set after giving input signals to all the operation members 20a, 20b, 21a, 21b, 21c, and 22 in the SET state, the state is the same as the ALL LOCK in FIG.
[0017]
When the shutter release switch 31 (FIG. 4) is input in the SET state, even if other operation members can be input, photographing is effectively prohibited. When resetting from the input prohibited state, the lever 100a is reset from the LOCK position to the SET position. If the lever 100a is further rotated to the OFF position, the input prohibited state is released. If the lock switch 100 is turned on when the main power is turned off (set to other than OFF) and then the main power is turned on, the input is not performed. In this case, the lever 100a is returned to the OFF position, and then the lever is again turned on. Rotate 100a to the SET position and enter the preparation phase for LOCK. Also, if the operation members 20a, 20b, 21a, 21b, 21c, and 22 are operated after the lock switch 100 is turned on, a warning is issued in the viewfinder and the like when the shutter release switch 31 (FIG. 4) is turned on. It is preferable that a function for alerting a person is added.
[0018]
It should be noted that the present invention is not limited to the circuit shown in FIG. 4, and it is possible not only to directly operate a switch provided on the camera, but also to be set by remote control or using a code. In addition, when auto is selected in the shooting mode, the LOCK switch 35 is disabled.
[0019]
Next, an effective method of using the above configuration will be specifically exemplified.
[Example 1]
[0020]
Prohibit shutter release. It is possible to avoid useless shooting in an environment in which the release button is likely to be pressed accidentally, such as when the main power is turned on temporarily. When moving to shooting, simply rotating the lever 100a does not require wake-up time and can be expected to be effective for shooting that requires a quick response.
[Example 2]
[0021]
All of the operation members 20a, 20b, 21a, 21b, 21c, and 22 on the back cover (rear) side are locked in a desired mode. When the camera is put on the shoulder while the main power is on and the crowd is moved, the body and the back cover side of the camera may be rubbed and the operation members 20a, 20b, 21a, 21b, 21c, and 22 may be touched. . Since it has been reported that many also the photographer to move in the state of the main power source ON at the time of shooting, effects can be expected much.
[0022]
FIG. 4 is a block connection diagram showing the built-in circuit of the camera, FIG. 5 is a flowchart for explaining the operation of the control circuit 37, and FIG. 6 is a conceptual diagram for supplementing and explaining the flowchart of FIG.
[0023]
As shown in FIG. 4, the built-in circuit of the camera is configured as an input / output circuit for the control circuit 37. The ALL LOCK switch 30 is switched on when the lever 100a is set to the ALL LOCK position. The release switch 31 is switched on by half-pressing a shutter release button (not shown). The release switch 32 is switched on when the shutter release button is fully pressed. The OFF switch 33 is switched on when the lever 100a is set to the OFF position. The SET switch 34 is switched on when the lever 100a is set to the SET position. The LOCK switch 35 is switched on when the lever 100a is set to the LOCK position.
[0024]
The main power switch 36 is a switch that controls power ON / OFF of the entire camera, and is connected to the control circuit 37 in order to detect the ON / OFF state of the main power switch 36. The function input device 38, the photographing device 40, and the photographing mode auto device 41 are devices that are connected to the control circuit 37 and exhibit a photographing function as a normal camera. The function lock device 39 is a device that locks and unlocks the functions of the operation members 20a, 20b, 21a, 21b, 21c, and 22 in response to a command from the control circuit 37.
[0025]
Next, the operation of the control circuit 37 when the operation shown in FIG. 6 is performed will be described with reference to the flowchart of FIG.
[0026]
When the program starts, the ON / OFF state of the main power switch 36 is detected in step S1. When the main power switch 36 is OFF, the program is immediately terminated. When the main power switch 36 is ON, the process proceeds to step S2.
[0027]
In step S2, it is detected whether or not the OFF switch 33 is turned on. When the OFF switch 33 is turned on (when the lever 100a is in the OFF position), the mode change program is terminated because the state is not shown in FIG. 6A. When the OFF switch 33 is not turned on, the process proceeds to step S3. In step S3, it is detected whether or not the SET switch 34 is turned on. When the SET switch 34 is not turned on (when the lever 100a is not in the SET position), the mode change program is terminated because the state is not shown in FIG. 6A. When the SET switch 34 is on, the process proceeds to step S4.
[0028]
In step S4, after waiting for a change from the state in which the SET switch 34 is turned on to a state in which it cannot be turned on, the process proceeds to step S5. In step S5, it is detected whether or not the LOCK switch 35 is turned on. When the LOCK switch 35 is not turned on (when the lever 100a is not in the LOCK position), since the state does not change to the state of FIG. 6B, the process returns to step S4 and the above-described operation is repeated. When the LOCK switch 35 is turned on, the process proceeds to step S6.
[0029]
When the camera user does not need to change the mode using the operation members 20a, 20b, 21a, 21b, 21c, and 22 (locking is required) in steps S2 to S5 described above, the lever 100a Is moved from the OFF position to the SET position. When the lever 100a is in the SET position (FIG. 6 (a)), the operation member 20a, 20b, 21a, 21b, 21c, and 22 to be selected are input or displayed in a necessary mode, and then the lever 100a is moved. Move to the LOCK position (FIG. 6B). At this time, the mode is not changed by the operation members 20a, 20b, 21a, 21b, 21c, and 22. That is, it becomes a locked state.
[0030]
In step S6 of FIG. 5, a photographing process is performed, and in step S7, it is determined whether or not the photographing is finished. When shooting is finished, the program ends. When it is determined that shooting has not been completed, the process proceeds to step S8.
[0031]
In step S8, when shooting is attempted, when the photographer wants to change the mode quickly, or when it is necessary to change the mode in response to a sudden change in the state of the subject. Determine whether to reset.
[0032]
In step S9, the process proceeds to a case where the LOCK switch is not reset in step S8, and it is determined whether the LOCK switch is released and set again from the beginning, or whether shooting is continued once set. Note that step S9 serves to reconfirm the determination result in step S8, and can be omitted.
[0033]
Figure 7 is a front view showing a second embodiment of a control panel, which shows an enlarged operation panel 50 of the camera.
[0034]
Various shooting modes are set by rotating the mechanical mode dials 51a to 51f. After the setting, when the lock switches 52a to 52f provided are turned on, the dials of the mode dials 51a to 51f are disabled due to the mechanical lock. For example, the shutter speed can be fixed at a certain speed. When the lock switches 52a to 52f are turned OFF, the mechanical locks of the mode dials 51a to 51f are released.
[0035]
Figure 8 is a front view showing a third embodiment of the control panel shows the enlarged operation panel 60 of the camera. The operation panel 60 is provided on the surface of a display device such as a liquid crystal, and displays values set by operating the touch panels 61a to 61f. For example, the rear liquid crystal 90 in FIG. 1 may also serve as the operation panel 60.
[0036]
The touch panel 61a is a panel that changes the shutter speed. The touch panel 61b is a panel that changes the range in which the light striking the photometric mode subject is measured. Depending on the subject, a mode such as center-weighted photometry, spot photometry, or multi-photometry can be used properly. FIG. 8 illustrates the case of center-weighted photometry. The touch panel 61c is a panel for changing the drive, and can use different modes for changing the number of images that can be shot at one time. Generally, it is divided into single frame shooting (S), slow continuous shooting (Hs), and high-speed continuous shooting (Hc). FIG. 8 illustrates the case of high-speed continuous shooting. The touch panel 61d is a panel that changes the aperture. The touch panel 61e is a panel that performs exposure correction. The proper exposure displayed by the camera can be changed intentionally. FIG. 8 illustrates a case where correction is made to the two-stage open side from the proper exposure. The touch panel 61f is a panel for changing the white balance. Different modes for color adjustment can be used for white subjects. FIG. 8 illustrates a case where the user selects a mode for determining a hue.
[0037]
Various shooting modes are set by touching the touch panels 61a to 61f with a finger. After the setting, when the lock switches 62a to 62f provided therewith are turned on by touching with a finger, the setting of the touch panels 61a to 61f cannot be changed due to the electric lock. For example, the shutter speed may be fixed at a certain speed. It becomes possible. If the lock switches 62a to 62f are turned off by touching them with a finger, the electric locks of the touch panels 61a to 61f are released.
[0038]
Figure 9 is a conceptual diagram showing a third embodiment of the control panel. The camera includes a memory (storage means) (not shown) that stores a plurality of combinations in which lock switches 62a to 62f (lock members) selectively lock the touch panels 61a to 61f (operation members), and the memory (storage means). Touch panels 61g to 61i (see FIG. 8) for selecting any one combination from the plurality of combinations stored in.
[0039]
The touch panel 61g is a touch panel that selects one of three types of combinations for selectively locking the touch panels 61a to 61f in the portrait mode. The touch panel 61h is a touch panel that selects one of three types of combinations for selectively locking the touch panels 61a to 61f in the distant view mode. The touch panel 61i is a touch panel that selects and operates one of three types of combinations that selectively lock the touch panels 61a to 61f in the sport mode.
[0040]
That is, when the user selects a desired shooting mode, there are several combinations of items that can be locked in advance (three types in the embodiment), and one of them is used. For example, when the portrait mode is selected, the combinations shown in FIG. 9 are set for the six items below the shutter speed depending on whether the lock is turned OFF or ON. Similarly, in the distant view mode and the sport mode, a combination as shown in FIG. 9 is prepared, and the user can quickly cope with shooting by selecting the optimum mode according to the desire. The effect of preventing erroneous signal input can be expected.
[0041]
【Effect of the invention】
According to the onset bright, that Do is possible to prevent an input by operating the operation unit erroneous.
