A digital camera having communication ability that has the function of a digital camera and a cellar phone has previously been proposed.
A cellar phone having a technique for announcing an incoming call by a sound, or by vibration has been known.
However, as for the digital camera having communication ability (hereafter called “a communication camera”), when a user tries to shoot a picture after communication, the problem of losing a chance for shooting a picture arises because operation to switch to picture shooting from communication is complex. On the other hand, when the user receives an incoming call from another communication device during picture shooting, the problem of difficulty in starting the communication immediately arises because operation of switching to communication from picture shooting is complex.
Furthermore, as for the communication camera announcing the incoming call by vibration, when the user receives the incoming call from another communication device during shooting a picture, the problem of camera-shake caused by the vibration arises, resulting in a blurred picture.
Furthermore, as for the communication camera announcing the incoming call by a sound, when the user receives the incoming call from another communication device during film shooting and audio recording, the problem that the sound of the incoming call is unnecessarily recorded on a medium arises.
Thus, there is a need for a camera having communication ability that switches a mode quickly between a communication mode and a shooting mode. Furthermore, a camera having communication ability should not receive bad influence from vibration and the sound that announces an incoming call.

FIG. 3 is a flow chart that shows controls performed by the CPU 209 of the communication camera 1 in accordance with one embodiment of the present invention.
The present flowchart starts when the user receives an incoming call sent from a caller.
In step S1, it is determined whether or not the mode chosen by the mode switch button group 9 is a still image shooting mode. If it is determined that the mode chosen by the mode switch button group 9 is the still image shooting mode, then the process advances to step S2. If the mode chosen by the mode switch button 9 is not the still image shooting mode, then the process advances to step S11.
In step S2, announcing the incoming call by vibration or displaying is prohibited, and the announcement of the incoming call by a sound is performed, announcing to the caller with voice. Since composition of a picture is important in a still picture, the announcement by displaying the message is prohibited to avoid causing the picture displayed on the monitor 4 to be hidden partly behind the displayed message. However, if it is allowed that the picture is hidden, the announcement by displaying the message is usable.
In step S3, the voice message of whether to interrupt shooting or not, or the voice message of whether to interrupt recording or not, is read out from the memory in the CPU 209 and is output through the loudspeaker 3.
In step S4, it is determined whether or not the “YES” 6 button is pressed. If it is determined that the “YES” button 6 is pressed, then the process advances to step S5. If the “YES” button 6 is not pressed, the process advances to step S8.
In step S5, the current mode is switched from the shooting mode or the sound record mode to the communication mode, resulting in the communication with the caller.
In step S6, it is determined whether or not the communication is completed. If it is determined that the communication is completed, then the process advances to step S7. If the communication is not completed, step S6 is repeated until the completion of the communication is determined.
In step S7, the mode is returned to the shooting mode or the sound record mode.
In step S8, subsequent to step S4 in which it is determined that the “YES” button 6 is not pressed, it is determined whether or not the “No” button 7 is pressed. If it is determined that the “No” button 7 is pressed, then the process advances to step S10. If the “No” button 7 is not pressed, the process advances to step S9.
In step S9, it is determined whether or not the timer of the CPU 209 measures 10 seconds after the incoming call is received. If it is determined that the timer measures 10 seconds after the incoming call is received, then the process advances to step S10. If the timer does not measure 10 seconds, then the process returns to step S3.
In step S10, the flow shown in FIG. 4 is performed.
In step S11, subsequent to step S1 in which it is determined that the mode is not the shooting mode, it is determined whether or not the mode is one of the moving video mode and sound record mode. If it is determined that the mode is one of the moving video mode and sound record mode, then the process advances to step S12. If the mode is not one of the moving video mode and sound record mode, the process advances to step S19.
In step S12, it is determined whether or not shooting or sound recording is performed in the moving video mode or the sound record mode. If it is determined that shooting or sound recording is performed in the moving video mode or the sound record mode, then the process advances to step S13. If shooting or sound recording is not performed, the process returns to step S2.
In step S13, the announcement by vibration or voice is prohibited, and the incoming call is indicated on the monitor 4, and then the caller's name or information specifying the caller is indicated on the monitor 4.
In step S14, the indication of whether to communicate with, the caller by interrupting shooting or recording, is read out from the memory of the CPU 209 and displayed on the monitor 4.
In step S15, it is determined whether or not the start button 5 is pressed. If it is determined that the start button 5 is pressed, then the process advances to step S5. If the start button 5 is not pressed, the process advances to step S16.
In step S16, it is determined whether or not the “No” button 7 is pressed. If it is determined that the “No” button 7 is pressed, then the process advances to step S18. If the “No” button 7 is not pressed, the process advances to step S17.
In step S17, it is determined whether or not the timer of the CPU 209 measures 10 seconds after the incoming call is received. If it is determined that the timer of the CPU 209 measures 10 seconds after the incoming call is generated, then the process advances to step S18. If the timer of the CPU 209 does not measure 10 seconds, the process returns to step S 14.
In step S 18, the flow shown in FIG. 4 is performed. In step S19, the announcement of the incoming call is performed by vibration, sound, or indication, and the caller's name or information identifying the caller is announced, because it is determined that the mode chosen by the mode switch button 9 is not the still video mode in step S1, and it is determined that the mode is not one of the moving video mode and the sound record mode in step S11. In step S 20, the communication starts.
In step S 21, it is determined whether or not the communication is finished. If it is determined that the communication is finished, then the present flow is completed. If the communication is not completed, the process returns to step S 20, and the communication continues.
FIG. 4 is a flow chart that shows controls performed in step S10 and step S18 in FIG. 3.
In step S201, it is transmitted to the caller that the user is not able to communicate with the caller and waiting for the caller's message.
In step S202, when the caller sends the message to the user, the caller's telephone number and the caller's message are recorded. The message can be stored in the memory of the communication camera 1, or in the predetermined memory at the telephone company.
In step S203, it is determined whether or not the mode is switched to the communication mode from the shooting mode. If it is determined that the mode is switched to the communication mode, then the process advances to step S204. If the mode is not switched to the communication mode, determination that the mode is switched to the communication mode from the shooting mode is repeated.
In step S204, it is determined whether or not the caller's message is recorded. If it is determined that the caller's message is recorded, then the process advances to step S205. If the caller's message is not recorded, the process advances to step S210.
In step S205, it is asked whether or not to listen to the message by voice or displayed indication.
In step S206, it is determined whether or not the “Yes” button 6 is pressed. If it is determined that the “Yes” button 6 is pressed, then the process advances to step S207. If the “Yes” button 6 is not pressed, the process advances to step S208.
In step S207, the recorded message is reproduced and the process is completed.
In step S208, subsequent to step S206 in which it is determined that the “Yes” button 6 is not pressed, it is determined whether or not the “No” button 7 is pressed. If it is determined that-the-“No” button 7 is pressed, then the present flow is completed. If the “No” button 7 is not pressed, the process advances to step S209.
In step S209, it is determined whether or not the timer measures 10 seconds after the message is listened or transmitted to the caller. If it is determined that the timer measures 10 seconds after the message is listened or announced, then the present flow is completed. If the timer does not measure 10 seconds, the process returns to step S206.
In step S210, it is announced, by the voice or the displayed indication, whether or not to telephone the caller.
In step S211, it is determined whether or not the “Yes” button 6 is pressed. If it is determined that the “Yes” button 6 is pressed, then the process advances to step S212. If the “Yes” button 6 is not pressed, the process advances to step S214.
In step S212, the recorded telephone number is dialed.
In step S213, the communication starts.
In step S214, it is determined whether or not the communication is completed. If it is determined that the communication is completed, then the present flow is completed. If communication is not completed, the process returns to step S213, and the communication continues.
In step S215, subsequent to step S211 in which it is determined that the “Yes” button 6 is not pressed, it is determined whether or not the “No” button 7 is pressed. If it is determined that the “No” button 7 is pressed, then the present flow is completed. If the “No” button 7 is not pressed, the process advances to step S216.
In step S216, it is determined whether or not the timer measures 10 seconds after the user telephones the caller or transmits the message to the caller. If it is determined that the timer measures 10 seconds after the user telephones the caller or transmits the message to the caller, then the present flow is completed. If the timer does not measure 10 seconds, the process returns to step 211.
Thus, in accordance with the present invention, the exposed picture does not become blurred by camera-shake, because the announcement of the incoming call by vibration is prohibited during the shooting time of the still picture, the standby time for the still picture and the standby time for the moving picture. Furthermore, in the case of moving picture, the exposed picture does not become blurred due to camera-shake, and the communication camera does not record the sound of the incoming call, because the announcement of the incoming call by vibration or sound is prohibited during shooting.
Furthermore, in accordance with the present the invention, the user can start shooting at once after completion of communication, because the mode is switched to the shooting mode immediately responsive to the completion of the communication while the mode is the communication mode.
Furthermore, in accordance with the present invention when the incoming call is announced during shooting, by stopping shooting, the user can switches the mode to the communication mode, thereby starting communication immediately.
Furthermore, when the communication camera receives the message during shooting, by sending the caller the message automatically that the user can not correspond to the caller, the user can send the user's state to the caller without interrupting shooting.
Furthermore, when the communication camera receives the message during shooting, by storing caller's telephone number automatically, the user can telephone the caller immediately after the completion of the shooting.
Furthermore, when the communication camera receives the message during shooting, by storing the caller's message, the user can learn the caller's message without interrupting the shooting.
Furthermore, the user can shoot as soon as he finishes the communication because the mode is switched to the shooting mode responsive to the completion of communication. Therefore, the user does not loose a shooting chance.
Furthermore, by storing a signal from another communication device during shooting, the signal from another communication device can be stored in the memory of the communication camera without interrupting shooting.
As described above, according to the first embodiment of the present invention, by changing the announcing method of the incoming call according to a state of the communication camera, exposed image data does not receive bad influences from the incoming call announcement.
[Second Embodiment]
A second embodiment of the camera according to this invention will be described with reference to FIG. 5. FIG. 5 is a flow chart showing the operation of CPU 209 in the second embodiment. The explanation of the camera construction is omitted here because the camera construction in the second embodiment is the same as that in the first embodiment.
The flowchart shown in FIG. 5 starts when the camera 1 receives a signal sent from other communication device in the case where the incoming call announcement by vibration is set in the camera 1.
In step S301, by detecting an operation state of the start button 5 and the imaging element 201, it is determined whether or not the camera 1 is in the shooting state. If the start button 5 is fully depressed to subject the imaging element 201 to light or the imaging element 201 is subjected to light responsive to fully depressing of the start button 5, then it is determined that the camera 1 is in the shooting state, and the process advances to step S302. If the start button 5 is not fully depressed and the imaging element 201 is not subjected to light, then it is determined that the camera 1 is not in the shooting state, and the process advances to step S308.
In step S302, the incoming call announcement by vibration is prevented by stopping the vibration circuit 212. The process advances to step S303 after completion of the process in step S302.
In step S303, after it is detected which announcing means is set to the camera 1, either the announcing means except vibration or the default announcing means is performed. For example, if the announcing means set to the camera 1 is sound or vibration, then the incoming call announcement only by sound is started. If the announcing means set to the camera 1 is only vibration, then the incoming call announcement by the default announcing means except vibration is started. If the default announcing means is sound or voice, the incoming call announcement by sound or voice is started, and if the default announcing means is the display on the monitor 4, the incoming call announcement by the display is started. Then, the process advances to step S304.
In step S304, by detecting an operation state of the start button 5 and the imaging element 201, it is determined whether or not the camera 1 has shot the picture. If the start button 5 is not fully depressed and the imaging element 201 is not subjected to light, then it is determined that the camera 1 has shot the picture, and the process advances to step S305. If the start button 5 is fully depressed or the imaging element 201 is subjected to light, then it is determined that the camera 1 is in the shooting state, and the process waits completion of shooting in step S304.
In step S305, by permitting the vibration circuit 212 to be driven, the incoming call announcement by vibration is allowed. Then, the process advances to step S306 after completion of the process in step S305.
In step S306, it is determined whether or not the incoming call announcement, which has been started in step S303, continues after completion of shooting. If the incoming call announcement continues, then the process advances to step S307. If the incoming call announcement has already completed, then the present flow finishes.
In step S307, the vibration circuit 212 is driven, and the incoming call announcement by vibration is started. Regarding the incoming call announcement by means except vibration, started in step S303, it is acceptable to finish the incoming call announcement by means except vibration when the incoming call announcement by vibration starts, or it is also acceptable to continue the incoming call by means except vibration. When the process in step S307 is completed, the present flow ends. If it is determined that the camera 1 is not in the shooting state in step S301, then the process advances to step S308.
In step S308, the vibration circuit 212 is driven, and the incoming call announcement by vibration is started. Furthermore, it is detected which announcing means is set to the camera 1. If the incoming call announcement by means except vibration is set, the incoming call announcement by means except vibration is also started. After completion of the process in step S308, the process advances to step S309.
In step S309, the operation of the start button 5 is made ineffective. If the start button 5 is turned on the imaging means does not record. The process advances to step S310 after completion of the process in step S309.
In step S310, it is determined whether or not the incoming call announcement by vibration, which is started in step S308, is finished. If the incoming call announcement is finished, then the process advances to step S311. If the incoming call announcement is not finished, then the process waits in step S310.
In step S311, the start button 5 is made effective, and by turning the start button 5 on, it becomes possible to shoot. The present flow ends when the process in step S311 has finished.
As described above, according to the second embodiment of the present invention, it is determined whether or not the camera 1 is in the shooting state upon receiving an incoming call. If the camera 1 is in the shooting state, then the incoming call announcement by vibration is prevented. Therefore, camera-shake does not occur. If the camera 1 is not in the shooting state, then it is possible to perform the incoming call announcement every time, even in the standby state of shooting.
Furthermore, since operation of the start button 5 is made ineffective while incoming call announcement by vibration continues, it is possible to avoid camera-shake by the vibration.
Furthermore, in the second embodiment, since it is determined whether or not the camera 1 is in the shooting state upon receiving the incoming call, the present invention is applicable to a type of camera that can communicate or shoot without changing the operation mode.
As for determination of the state of the shooting operation, in the second embodiment, it is determined whether or not the start button 5 is fully depressed so that the imaging element 201 is subjected to light. However, the present invention is not limited to the determination as described in the second embodiment. It is possible to determine the state of the shooting operation by determining whether or not the start button 5 is lightly pressed. In this case, the light press of the start button 5 performs focussing and metering operations, which are preliminary operations of shooting.
Furthermore, in the second embodiment of the present invention, by making the operation of the start button 5 ineffective during the incoming call announcement by vibration, the camera 1 controls the shooting using the imaging element 201 to be prevented. However, the present invention is not limited to the control, during the incoming call announcement by vibration, as described in the second embodiment. While the incoming call announcement by vibration is performed, it is possible to control the shooting such that an imaging signal is not output from the imaging element 201, or is not input into the flash memory 205.
Furthermore, in the second embodiment of the present invention, the camera 1 controls the shooting using the imaging element 201 to be prevented during the incoming call announcement by vibration. However, it is desirable that the shooting using the imaging element 201 is possible when an event or accident that must be recorded at once occurs even during the incoming call announcement by vibration.
Accordingly, in the case where the start button 5 is turned on during the incoming call announcement by vibration, it is possible to allow the camera 1 to shoot after announcing a warning that an exposed image become blur because of camera-shake.
Furthermore, it is possible to allow the camera 1 to shoot only when the combined operation of the start button 5 and other specific operating member is performed, even during the incoming call announcement by vibration. Furthermore, it is also possible to have a mode wherein the start button 5 is set effective even during the incoming call announcement by vibration. Furthermore, it is also possible to have an operation member such that the incoming call announcement is removed when the user wants to stop the shooting during the incoming call announcement by vibration.
Furthermore, in the second embodiment of the present invention, the incoming call announcement is prevented during the shooting operation, assuming that shooting is performed without recording sound. However, in the case of the apparatus able to shoot and record sound at the same time, such as a camcorder, it is possible to prevent not only the incoming call announce by vibration but also the incoming call announce by sound or voice.
As described above, according to the second embodiment of the present invention, by changing the control of the imaging means, it is possible for the user to avoid receiving bad influence to the imaging data.
Although the present embodiment is explained on a digital camera capable of shooting both of a still picture and a moving is picture, it is also applicable to a digital camera only for a still picture. And also, it is applicable to a silver-halide camera.
