[0032]
As described above, according to the present embodiment, notification of incoming calls due to vibration is prohibited during still image shooting, standby, and moving image shooting standby, so that the shot image is not blurred. In addition, during shooting of a moving image, notification of an incoming call by vibration or sound is prohibited, so that an image being shot is not blurred and a ring tone is not recorded.
[0033]
In addition, since the shooting is interrupted and the mode is changed to the call mode and then the mode is returned to the shooting mode in response to the end of the call, the shooting can be resumed immediately after the end of the call.
In addition, when there is an incoming call notification during shooting, the operation can be switched to the call mode by an operation to stop shooting, so that a call can be made immediately after shooting is stopped.
[0034]
In addition, when an incoming call is received during shooting, a message indicating that a call cannot be made to the other party is automatically transmitted, so that the other party can be informed of his / her situation without interruption.
In addition, when a call is received during shooting, the other party's telephone number is automatically stored, so that a call can be made after shooting is completed.
[0035]
In addition, since the other party's message can be stored when an incoming call is received during shooting, the other party's message can be stored without interrupting shooting, and the requirements of the other party after shooting can be known.
Next, a second embodiment of the present invention will be described with reference to FIG.
FIG. 5 is a flowchart showing a control procedure of the CPU 209 in the second embodiment of the present invention. In addition, since the structure of the camera in 2nd Embodiment is the same as what was demonstrated in previous embodiment, description is abbreviate | omitted here.
[0036]
The flowchart shown in FIG. 5 starts when the camera 1 receives a communication from another communication means in a state where the incoming notification by vibration is selected.
In step S301, the states of the recording start button 5 and the image sensor 201 are detected, and it is determined whether or not the camera 1 is performing a shooting operation. When the recording start button 5 is in a fully pressed state that causes the image sensor 201 to perform exposure, or when the image sensor 201 is in the middle of an exposure period in response to the fully pressed state of the recording start button 5, the camera 1 performs a shooting operation. It is determined that it is in the middle and the process proceeds to step S302. If the recording start button 5 is off and the image sensor 201 is not in the exposure period, it is determined that the camera 1 is not in a shooting operation, and the process proceeds to step S308.
[0037]
If it is determined in step S301 that the camera 1 is performing a shooting operation, the process proceeds to step S302. In step S302, the incoming notification by vibration is prohibited by prohibiting driving of the vibration circuit 212. When the process of step S302 ends, the process proceeds to step S303.
In step S303, the setting state of the incoming notification of the camera 1 is detected, and the incoming notification is started by a method of removing vibration from the setting state, a method set by the user or a method set by default. As an example, when the incoming call notification method is set to vibration and sound, the incoming call notification using only sound is started. As another example, when the incoming call notification method is set to only vibration, incoming call notification is started by a method set by default from incoming notifications other than vibration. When the default incoming notification is a notification by sound or voice, the incoming notification by sound or voice is started. When the default incoming notification is a notification by display on the display unit 4, an incoming notification message to the display unit 4 is displayed. Start displaying. When the process of step S303 is completed, the process proceeds to step S304.
[0038]
In step S304, the states of the recording start button 5 and the image sensor 201 are detected, and it is determined whether or not the photographing operation is completed. If the recording start button 5 is in the OFF state and the image sensor 201 is not in the exposure period, it is determined that the shooting operation has been completed, and the process proceeds to step S305. If the recording start button 5 is in a fully pressed state that causes the image sensor 201 to perform exposure, or if the image sensor 201 is in the middle of an exposure period in response to the fully pressed state of the recording start button 5, the shooting operation is ongoing. And waits in step S304.
[0039]
In step S305, an incoming notification by vibration is permitted by permitting driving of the vibration circuit 212. When the process of step S305 is completed, the process proceeds to step S306.
In step S306, it is determined whether or not the incoming call notification started in step S303 continues even after the photographing operation is completed. If the incoming notification continues, the process proceeds to step S307. If the incoming call notification has been completed, the processing of this flow is terminated.
[0040]
In step S307, the vibration circuit 212 is driven to start incoming notification by vibration. Note that the incoming notification by a method other than the vibration started in step S303 may be terminated when the incoming notification by vibration is started, or the notification may be continued as it is. When the process of step S307 is completed, the process of this flow ends.
[0041]
If it is determined in step S301 that the camera 1 is not in a shooting operation, the process proceeds to step S308. In step S308, the vibration circuit 212 is driven to start an incoming notification by vibration. In addition, when the incoming notification setting is detected and an incoming notification of a method other than vibration is set, the incoming notification is also started. When the process of step S308 is completed, the process proceeds to step S309.
[0042]
In step S309, the operation of the recording start button 5 is disabled, and control is performed so that recording by the imaging unit is not performed even when the recording start button 5 is turned on. When the process of step S309 is completed, the process proceeds to step S310.
In step S310, it is determined whether or not the incoming call notification started in step S308 has ended. If the incoming notification has been completed, the process proceeds to step S311. If the incoming notification has not ended, the process waits in step S310.
[0043]
In step S311, the operation of the recording start button 5 is validated, and control is performed so that shooting can be performed by turning on the recording start button. When the process of step S311 is completed, the process of this flow ends.
As described above, according to the second embodiment, when an incoming call is received, it is determined whether or not the shooting operation is being performed. If the shooting operation is being performed, the incoming notification by vibration is prohibited. There is no end. Further, when the photographing operation is not being performed, the incoming call notification by vibration can be performed even in the photographing standby state in the photographing mode.
[0044]
Further, since the operation of the recording start button 5 is invalidated while the incoming call notification by vibration is performed, it is possible to avoid the risk of obtaining a photographed image blurred by vibration.
In the second embodiment, since the determination is made on whether or not a shooting operation is being performed at the time of an incoming call, a type that can be performed at any time without any particular switching of the operation mode for calls and image shooting. It can also be applied to other cameras.
[0045]
Note that, regarding the determination of the shooting operation in the second embodiment, the state of the recording start button 5 is determined based on whether or not the imaging element 201 is fully pressed to perform exposure for recording. The determination of the operation is not limited to that described in the second embodiment, and the state of the recording start button 5 causes the camera 1 to perform a focusing operation, a photometric operation, etc., which are preliminary operations for exposure. You may discriminate | determine by whether it is a pushing state.
[0046]
Note that in the second embodiment, while the incoming call notification due to vibration is performed during the non-photographing operation, the operation of the recording start button 5 is disabled so that the subject photographing by the imaging unit 201 is prohibited. . However, the control for the shooting operation while the incoming call notification by vibration is performed is not limited to that described in the second embodiment, and the imaging unit is in operation while the incoming call notification by vibration is being performed. The image signal output from 201 may be prohibited, or the recording to the flash memory 205 may be prohibited.
[0047]
Further, in the second embodiment, control is performed so as to prohibit subject photographing by the imaging unit 201 while an incoming call notification due to vibration is performed during a non-photographing operation. However, the subject photographing by the image pickup means 201 can be taken even in the middle of receiving the incoming call notification due to vibration in a scene that requires urgency and immediacy, such as an evidence photo of an incident / accident. It is desirable. For this reason, if the recording start button 5 is operated while the incoming call notification by vibration is being performed and the camera is turned on, the camera is allowed to shoot after warning that there is a possibility that the shot image may be affected by shaking. You may control to do. Further, only when the recording start button 5 and another specific operation member are operated in combination, it may be controlled to allow photographing even while the incoming call notification by vibration is being performed. Further, it may have a mode that can be set in advance so that the operation of the recording start button 5 is valid even while the incoming call notification by vibration is performed. Further, if it is desired to take a picture while the incoming call notification by vibration is performed, an operation means that can immediately cancel the incoming call notification by vibration may be provided.
[0048]
In the second embodiment, the embodiment has been described on the assumption that only image shooting is performed. Therefore, only the incoming call notification by vibration is controlled during the shooting operation, but the sound is recorded simultaneously with the image of the video camera or the like. The device capable of doing so may be configured to prohibit not only the incoming call notification by vibration but also the incoming call notification by sound or voice during the photographing operation.
[0049]
In the first and second embodiments, the electronic camera that can shoot a moving image and a still image has been described. However, the electronic camera can shoot only a still image. It can also be realized with a film camera that records on a silver salt film.
[0050]
【The invention's effect】
As described above, according to the present invention, since the imaging control using the imaging unit is changed while the incoming notification by vibration is performed, the possibility that the image data is adversely affected by the incoming notification can be reduced. .
