Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[First Embodiment]
FIG. 1A is a configuration diagram of the image pickup apparatus of this embodiment. The photographing optical system 200 includes an aperture 11, a camera shake correction lens group 12, and a focus lens group 13, and can guide an optical image to the camera body 200. The camera body 200 includes an image pickup element 21 that photoelectrically converts the optical image of the photographing optical system 200 and a mechanical shutter 22 that adjusts the exposure time. The camera body 200 includes a rear liquid crystal 23 on the back surface, a small liquid crystal 24 and an optical system 25 on the finder, and can display an image captured by the image sensor 21. If the image sensor has an electronic shutter function, the mechanical shutter is unnecessary, and even if the mechanical shutter is provided, the mechanical shutter remains fully open when the exposure time is adjusted by the electronic shutter. At the time of shooting, by pressing the shutter button (not shown) shallowly to the first step, so-called "half-pressing", shooting conditions such as shutter speed and aperture value are set by the automatic focusing and automatic exposure mechanism. Further, by pressing the shutter button deeply from half-pressed to the second step, so-called "full-pressed", the electronic shutter function of the mechanical shutter 22 or the image sensor 21 operates to perform imaging.

FIG. 1B is a block diagram of the image pickup apparatus according to the first embodiment of the present invention. The camera body 200 includes an electric circuit 20, and the electric circuit 20 is equipped with a CPU, an image processing circuit, a control circuit, a sound reproduction circuit, and the like. The aperture 11, the image stabilization lens group 12, the focus lens group 13, and the mechanical shutter 22 are each controlled by a control circuit via a drive means (not shown). The signal photoelectrically converted by the image sensor 21 can be converted into digital data via an image processing circuit and stored in a recording medium (not shown). The finder unit is provided with an eyepiece sensor 26, and it is possible to detect whether or not the photographer is in contact with the finder unit. The camera body 200 includes an audio output unit 27, and can output audio reproduced by an audio reproduction circuit. If the audio output unit 27 is, for example, a speaker, the audio can be directly reproduced. Further, if the audio output unit 27 is a means for connecting to an external audio reproduction means such as earphones, the audio can be reproduced by the external audio reproduction means. The connection to the external audio reproduction means may be wired or wireless. The CPU is a processing device capable of electrically controlling all the above-mentioned elements. In FIG. 1, the control signal line is omitted, and only the flow of information between each element is indicated by an arrow.

FIG. 2 is a configuration diagram of the image pickup device of the present embodiment, in which an external audio output device 400 such as an earphone is wirelessly connected to the image pickup device 200 via an external device 300 such as a smartphone connected by wire. is there.

The image pickup apparatus 200 includes a rear liquid crystal 23, a finder 25, and a speaker 27. The external device 300 includes a liquid crystal 31, an operation button 33, and a speaker 34, and internally includes a recording unit capable of recording audio data.

The image pickup apparatus 200 and the external device 300 are connected by wireless communication using their respective built-in wireless communication units. Further, the external device 300 can connect an external audio output means 400 such as an earphone to the connection terminal 33 by wire. When the external audio output means 400 is connected, the audio is not output from the speaker 27 and the speaker 34, but is output from the external audio output means 400. By reproducing the sound with the earphones in this way, the photographer can hear the electronic sound of the image pickup device even in the above-mentioned silent mode.

The image pickup apparatus 200 has a function of reproducing sound when a predetermined condition is satisfied. As an example of the sound to be reproduced under a predetermined condition, there is a focusing electronic sound to be reproduced when the shutter button is half-pressed and then focused. There is also an electronic pseudo-shutter sound that is reproduced when the shutter button is fully pressed using an electronic shutter without mechanical shutter sound. There is also a warning sound that warns when the remaining battery level falls below a predetermined threshold value, and an operation sound that indicates that the operation has been performed when the operation button or the touch panel is pressed. Furthermore, voice that gives advice for good shooting by image analysis can be considered.

As described above, in the case of wireless communication, since it takes time to compress and decompress the voice data, there is a large delay from the start of the data transmission process to the reproduction by the earphone. In order to avoid this delay, the image pickup device 200 uses the sound output means 400 to which the external device 300 having the recording unit in which the sound data is recorded in advance is connected, and when the sound data is reproduced, the image pickup device 200 is used. Does not send audio data from, but only the playback command. By the reproduction command, the audio data corresponding to the reproduction command among the audio data recorded in the recording unit of the external device 300 connected to the audio output means 400 is reproduced from the audio output means 400. In this way, delay in audio reproduction can be prevented by transmitting only the reproduction command without transmitting the audio data.

The image pickup apparatus 200 has a recording unit inside, and can record audio data for recording audio data to be reproduced when a predetermined condition is satisfied and a reproduction command corresponding to each audio data. Further, the image pickup apparatus 200 has a wireless communication unit inside and can transmit voice data and a reproduction command. These recording units and wireless communication units are included in the above-mentioned voice reproduction circuit 20. In order to record the audio data to be reproduced in the recording unit of the external device 300 prior to the reproduction of the audio, the imaging device 200 refers to the external device 300 provided with the audio output means 400 and the recording unit capable of recording the audio data. And send the voice data. As a result, voice data is recorded in the recording unit of the external device 300. By transmitting the audio data from the imaging device 200 to the external device 300 in this way, even if the audio data is not recorded in advance in the recording unit of the external device 300, the audio can be reproduced only by transmitting a reproduction command. It becomes.

Hereinafter, with reference to FIG. 3, the timing at which the image pickup apparatus 200 transmits audio data to the external device 300 will be described. FIG. 3 shows a flow from when the image pickup device 200 and the external device 300 start establishing wireless communication to when all the voice data recorded in the recording unit of the image pickup device 200 is transmitted to the external device 300. It is assumed that the condition for reproducing the sound is satisfied on the way and the sound is reproduced by the external device 300. This flowchart is executed in cooperation with a CPU, an image processing circuit, a control circuit, a sound reproduction circuit, and the like mounted on the electric circuit 20 of the image pickup apparatus 200.

In S101, wireless communication between the image pickup apparatus 200 and the external device 300 begins to be established.

In S102, it is confirmed whether the establishment of wireless communication between the image pickup apparatus 200 and the external device 300 is completed. S102 is repeated until the establishment of wireless communication is completed.

In S103, among the untransmitted audio data recorded in the recording unit of the image pickup apparatus 200, the highest priority audio data transmission is started. When S103 is executed for the first time, all of the voice data is untransmitted, so the voice data transmission having the highest priority among all the voice data is started, and the voice data is transmitted in the order of priority from the next execution. .. In this way, by starting the transmission of the voice data at the timing when the wireless communication between the imaging device 200 and the external device 300 is established, the voice data is promptly transmitted to the external device 300, and the voice data is recorded in the external device 300. You can minimize the amount of time that is not being done.

In S104, it is confirmed whether the playback setting of the voice A is ON. If it is ON, the process proceeds to the flow S105 for reproducing the sound A, and if it is not ON, S105 is skipped and the process proceeds to S110. Here, the sound A is, for example, a focusing electronic sound to be reproduced when it is detected that the shutter is in focus after being pressed halfway. Hereinafter, the voice A will be described as being this focusing electronic sound. The flowchart is the same for the above-mentioned other voices.

In S105, it is confirmed whether the condition for reproducing the focusing electronic sound is satisfied. If the condition is satisfied, the process proceeds to S106, and if the condition is not satisfied, S106 is skipped and the process proceeds to S110.

In S106, the reproduction command of the image pickup device 200 focusing electronic sound is transmitted to the external device 300.

In S107, it is confirmed in the external device 300 whether the audio data of the focusing electronic sound has already been transmitted to the external device 300 and recorded in the recording unit of the external device 300. Here, if the condition for reproducing the focused electronic sound is satisfied after a sufficient time has elapsed since the transmission of the audio data was started in S103, the audio data has already been transmitted, and in that case, the process is sent to S108. move on. On the contrary, if the condition for reproducing the focused electronic sound is satisfied immediately after starting the transmission of the audio data in S103, the audio data has not been transmitted, and in that case, the process proceeds to S109.

In S108, the external device 300 reproduces the audio data of the focusing electronic sound recorded in the recording unit of the external device 300. In this way, since the audio data is reproduced by transmitting the reproduction command, even in wireless communication, from the time when the reproduction condition of the focused electronic sound is satisfied in S105 until the audio data is reproduced in S108. Delay can be prevented.

In S109, since the audio data of the focusing electronic sound is not recorded in the recording unit of the external device 300 in the external device 300, the external device 300 reproduces the general-purpose standard audio data. At least one of the general-purpose standard voice data may be recorded in advance by the external device 300, or may be generated based on a sine wave. In this way, when it becomes necessary to play the audio before transmitting the audio data, the focus is achieved by playing some sound that can be played by an external device without waiting for the transmission of the audio data. The photographer can hear the confirmation sound.

In S110, it is confirmed whether the voice data is being transmitted. If the voice data is being transmitted, the steps S104 to S110 are repeated in order to wait for the end of the voice data transmission. If the data has been transmitted, the process proceeds to S111.

In S111, it is confirmed whether or not all the audio data recorded in the recording unit of the image pickup apparatus 200 has been transmitted. If all the voice data has not been transmitted, the steps S103 to S111 are repeated in order to transmit the remaining voice data. If all the audio data has been transmitted, the process ends.

Here, in the predetermined priority order for transmitting the audio data to the external device in S103, the audio data to be reproduced when the image pickup apparatus is operated has priority. The audio data to be reproduced when the image pickup device is operated is, for example, a reproduction sound when the shutter button is operated or a reproduction sound when the touch panel is operated. Since such a reproduced sound is a sound that is frequently reproduced by the image pickup apparatus, it should be transmitted with priority. On the contrary, the audio data that is not the audio data to be reproduced when the image pickup device is operated may be, for example, a warning sound or image analysis that warns when the remaining battery level falls below a predetermined threshold value. It is a voice that gives advice for shooting. Since such a reproduced sound can be replaced by displaying the fact on the display means, the priority may be lowered.

As described above, the imaging device of this embodiment transmits audio data to an external device connected to the earphone, and records the audio data in the recording unit of the external device. Therefore, the sound can be reproduced by transmitting the reproduction command by wireless communication from the image pickup apparatus without recording the sound data in the recording unit of the external device in advance.

Further, the imaging device of this embodiment reproduces a voice that can be reproduced by an external device even if a voice command is transmitted before the transmission of the voice data is completed. Therefore, even if the condition for reproducing the audio data is satisfied before the transmission of the audio data is completed, the photographer can hear some audio.

Further, the imaging device of this embodiment starts transmitting audio data at the timing when wireless communication between the imaging device and the external device is established. Therefore, it is possible to promptly transmit the voice data to the external device and minimize the time when the voice data is not recorded in the external device.

In the example of FIG. 2, as an example of an external device provided with an audio output means and a recording unit capable of recording audio data, an earphone 400 is used as an audio output means, and an external device 300 is provided with a recording unit capable of recording audio data. An example of using an external device is shown. However, as shown in FIG. 4, if the circuit unit 51 built in the earphone 500 includes a recording unit capable of recording audio data and a wireless communication unit that wirelessly communicates with the image pickup device, the entire earphone 500 can be used as an audio output means. It can also be an external device.

[Second Embodiment]
In the second embodiment, an example will be described in which audio data is transmitted from the photographing device 200 to the external device 300 with priority starting from the timing when the operator sets the sound reproduction of the photographing device 200.

As an example of audio reproduction, a warning sound (exposure warning sound) when the exposure is out of the proper exposure and a warning sound (camera shake warning sound) when the shutter speed reaches the expected shutter speed will be described. It is not limited to. As for the exposure warning sound, if there is a possibility that the image will be too bright due to overexposure, it may be "overexposure", and it may be a dark image due to underexposure. In some cases, there is a warning sound that "underexposure is underexposed". Furthermore, if there is a part that is too bright and there is a possibility of partial overexposure, it is "overexposure", and if there is a part that is too dark and there is a possibility of partial blackout. Has a warning sound such as "black is crushed". As a camera shake warning sound, there is a warning sound such as "camera shake".

Hereinafter, with reference to FIG. 5, the timing of transmitting the voice data from the photographing device 200 to the external device 300 when the operator sets the voice reproduction of the exposure warning sound will be described. This flowchart is executed in cooperation with a CPU, an image processing circuit, a control circuit, a sound reproduction circuit, and the like mounted on the electric circuit 20 of the image pickup apparatus 200.

In S201, the establishment of wireless communication between the photographing device 200 and the external device 300 is started.

In S202, it is confirmed whether the establishment of wireless communication between the photographing device 200 and the external device 300 is completed. S202 is repeated until the establishment of wireless communication is completed.

Check in S203 whether the audio B playback setting is ON. If the playback setting of the voice B is ON, the process proceeds to the flow S204 for starting the transmission of the voice data. Here, the voice B is, for example, the above-mentioned exposure warning sound, such as "overexposure", "underexposure", "overexposure", and "black out". Hereinafter, the voice B will be described as being this exposure warning sound. The flowchart is the same for the above-mentioned other voices.

In S204, among the untransmitted audio data recorded in the recording unit of the photographing apparatus 200, the audio data B (exposure warning sound data) related to the audio B (exposure warning sound) is prioritized to start transmission. The exposure warning sound data is the above-mentioned voice data such as "overexposure", "underexposure", "overexposure", and "black out". In this way, by starting the transmission of the voice data to the external device 300 at the timing when the reproduction setting of the warning sound of the voice B is turned on, the voice data related to the voice B is not recorded in the external device 300. Time can be minimized.

In S205, it is confirmed whether the condition for reproducing the sound B is satisfied. If the condition is satisfied, the process proceeds to S206, and if the condition is not satisfied, S206 is skipped and the process proceeds to S210.

In S206, the reproduction command of the sound B of the photographing device 200 is transmitted to the external device 300.

In S207, the external device 300 confirms whether the voice data B has already been transmitted to the external device 300 and is recorded in the recording unit of the external device 300. Here, if the condition for reproducing the voice B is satisfied after a sufficient time has elapsed since the transmission of the voice data B was started in S204, the voice data B of the voice B has already been transmitted. If so, proceed to S208. On the contrary, if the condition for reproducing the voice B is satisfied immediately after the transmission of the voice data B is started in S204, the voice data B of the voice B has not been transmitted, and in that case, the process proceeds to S209.

In S208, the external device 300 reproduces the audio data B recorded in the recording unit of the external device 300. Since the voice data B is reproduced by transmitting the reproduction command in this way, even in wireless communication, from the time when the reproduction condition of the voice B is satisfied in S205 to the time when the audio data B is reproduced in S208. Delay can be prevented.

In S209, since the voice data B of the voice B has not yet been recorded in the recording unit of the external device 300 in the external device 300, the external device 300 reproduces the general-purpose standard voice data. At least one of the general-purpose standard voice data may be recorded in advance by the external device 300, or may be generated based on a sine wave. In this way, when it becomes necessary to reproduce the audio before transmitting the audio data B, there is an exposure warning by reproducing some sound that can be reproduced by an external device without waiting for the transmission of the audio data. The photographer can know that.

In S210, it is confirmed whether the voice data B is being transmitted. If the voice data is being transmitted, the steps S205 to S210 are repeated in order to wait for the completion of the transmission of the voice data B. If all the voice data B has been transmitted, the process proceeds to S211.

In S211 it is confirmed whether or not all the audio data recorded in the recording unit of the photographing apparatus 200 has been transmitted. All voice data includes not only voice data B but also other voice data such as camera shake warning sound data such as "camera shake". If all the voice data has not been transmitted, the steps S204 to S211 are repeated in order to transmit the remaining voice data. If all the audio data has been transmitted, the process ends.

In this way, among the untransmitted audio data recorded in the recording unit of the photographing apparatus 200 at the timing when the photographer sets a predetermined condition for reproducing the audio B (for example, the exposure warning sound), the audio data related to the audio B (For example, "Overexposure" etc.) is prioritized to start transmission. As a result, the voice data of the voice B, which is highly likely to be reproduced, can be quickly transmitted to the external device. As a result, it is possible to minimize the time during which the audio data that is likely to be reproduced is not recorded in the external device.

Further, in the above description, by repeating the loop from S204 to S211, all the audio data other than the audio B for which the photographer has set the reproduction is transmitted with a lower priority. However, it is not limited to this. For example, low-priority voice data (for example, camera shake warning sound) other than voice B need not be transmitted to the external device 300.

As described above, the photographing device of this embodiment transmits audio data to an external device connected to the earphone, and records the audio data in the recording unit of the external device. Therefore, the voice can be reproduced by transmitting the playback command by wireless communication from the photographing device without recording the voice data in the recording unit of the external device in advance.

Further, the photographing apparatus of this embodiment reproduces the voice that can be reproduced by the external device even if the voice command is transmitted before the transmission of the voice data is completed. Therefore, even if the condition for reproducing the audio data is satisfied before the transmission of the audio data is completed, the photographer can hear some audio.

[Third Embodiment]
In the third embodiment, the audio data is prioritized from the imaging device 200 to the external device 300, starting from the timing at which the audio reproduction condition of the audio for which the operator has set the audio reproduction setting in the photographing device 200 is satisfied. An example of transmitting is described.

Similar to the second embodiment, as an example of sound reproduction, a warning sound when the exposure is out of the proper exposure (exposure warning sound) and a warning sound when the shutter speed reaches the expected shutter speed (camera shake warning sound). Will be described as an example, but the present invention is not particularly limited to this.

The exposure warning sound when the exposure is out of the proper exposure includes, for example, an overexposure warning sound (“overexposure”) when the overall overexposure may result in an overexposed image. .. There is also an underexposure warning sound (“underexposure”) when there is a possibility of a dark captured image due to underexposure as a whole. In addition, there is an overexposure warning sound (“overexposure”) when there is a part that is too bright and there is a possibility of partial overexposure, and there is a part that is too dark and there is a partial overexposure. There is a black crush warning sound ("black crush") when there is a possibility.

Here, in order to make it easier to distinguish, the exposure warning sound is voice C, the overexposure warning sound constituting the exposure warning sound which is voice C is voice C1, the underexposure warning sound is voice C2, and the overexposure warning sound is voice C3. , The black crush warning sound will be referred to as voice C4, and the following description will be given. As a camera shake warning sound, there is a warning sound such as "camera shake".

Hereinafter, with reference to FIG. 6, the timing of transmitting audio data from the photographing device 200 to the external device 300 when the audio reproduction condition of the audio set by the operator is satisfied will be described. This flowchart is executed in cooperation with a CPU, an image processing circuit, a control circuit, a sound reproduction circuit, and the like mounted on the electric circuit 20 of the image pickup apparatus 200.

In S301, wireless communication between the photographing device 200 and the external device 300 starts to be established.

In S302, it is confirmed whether the establishment of wireless communication between the photographing device 200 and the external device 300 is completed. S302 is repeated until the establishment of wireless communication is completed.

In S303, it is confirmed whether the reproduction setting of the voice C (exposure warning sound) is ON. If the playback setting of the voice C is ON, the process proceeds to the flow S304 for confirming whether the playback condition of the voice C1 is satisfied.

In S304, it is confirmed whether or not the condition for reproducing the voice C1 is satisfied. If the condition is satisfied, the process proceeds to S305. If the condition is not satisfied, the confirmation of S304 is repeated. Here, it is explained that the reproduction condition of the voice C1 (overexposure warning sound) is satisfied among the playback conditions of the voice C, but the present invention is not limited to this, for example, the voice C2 (underexposure warning sound) and the like. The flow chart is the same for the other voices of.

In S305, a reproduction command for reproducing the audio C1 data (“overexposure”) constituting the audio C1 of the photographing device 200 is transmitted to the external device 300.

In S306, the external device 300 confirms whether the voice C1 data has already been transmitted to the external device 300 and is recorded in the recording unit of the external device 300. Here, if the condition for reproducing the voice C1 in S304 is satisfied after a sufficient time has elapsed since the transmission of the voice C1 data was started in S310 described later, the voice data of the voice C1 has already been transmitted. Proceeds to S307. On the contrary, when the condition for reproducing the voice C1 is satisfied for the first time in S304, or when the condition for reproducing the voice C1 is satisfied in S304 immediately after the transmission of the voice data C1 is started in S310 described later, the voice C1 data is transmitted. Is not completed, so proceed to S308.

In S307, the external device 300 reproduces the audio C1 data (“overexposure”) recorded in the recording unit of the external device 300. Since the voice data is reproduced by transmitting the reproduction command in this way, even in wireless communication, there is a delay from the establishment of the reproduction condition of the voice C1 in S304 to the reproduction of the voice data in S307. Can be prevented.

In S308, since the audio C1 data has not yet been recorded in the recording unit of the external device 300 in the external device 300, the external device 300 reproduces the general-purpose standard audio data. At least one of the general-purpose standard voice data may be recorded in advance by the external device 300, or may be generated based on a sine wave. In this way, if it becomes necessary to play the audio before transmitting the audio data, there is an overexposure warning by playing some sound that can be played by an external device without waiting for the transmission of the audio data. The photographer can know that.

In S309, it is confirmed whether the voice C1 data is being transmitted. When the flow of S309 is executed for the first time, S310 for starting the transmission of voice C1 data has not been executed yet, so the process proceeds to S310. If the voice data is being transmitted, the steps S304 to S309 are repeated in order to wait for the end of the voice C1 data transmission.

In S310, among the untransmitted audio data recorded in the recording unit of the photographing apparatus 200, the audio C1 data (“exposed is over”) related to the audio C1 having the highest priority is given the highest priority and transmission is started. To do. Send audio data to priority from the next execution. In this way, by starting the transmission of the voice data to the external device 300 at the timing when the playback condition of the voice C1 is satisfied, the time during which the voice data related to the voice C1 is not recorded in the external device 300 is minimized. be able to.

In general, overexposure tends to cause white crushing. Therefore, in S310, the voice data to be transmitted with priority next to the voice C1 data (“overexposure”) is prioritized so as to be the voice C3 data (“overexposure”).

In general, when the exposure is underexposed, black crushing is likely to occur. Therefore, in the same way, when the reproduction condition of the voice C2 (underexposure warning sound) is satisfied in S304, the voice data to be transmitted with priority after the voice C2 data (“underexposure”) is transmitted as voice. Prioritize the data so that it becomes C4 data ("blackened").

In S311 it is confirmed whether or not all the audio data recorded in the recording unit of the photographing apparatus 200 has been transmitted. All voice data includes not only voice data C but also other voice data such as camera shake warning sound data such as "camera shake". If all the voice data has not been transmitted, the steps S304 to S311 are repeated in order to transmit the remaining voice data. If all the audio data has been transmitted, the process ends.

In this way, when the photographer sets a predetermined condition for reproducing the voice C (for example, an exposure warning sound) and then the playback condition for the voice C is satisfied, the voice among the voice data not transmitted from the shooting device 200 Priority is given to voice data related to C (for example, "overexposure") is transmitted. As a result, the voice data of voice C, which is highly likely to be reproduced in the future, can be promptly transmitted to the external device. As a result, it is possible to minimize the time during which the audio data that is likely to be reproduced is not recorded in the external device.

Further, in the above description, by repeating the loop from S304 to S311, all the audio data other than the audio C set to be reproduced by the photographer is transmitted with a lower priority. However, it is not limited to this. For example, voice data having a low priority other than voice C does not have to be transmitted to the external device 300.

As described above, the photographing device of this embodiment transmits audio data to an external device connected to the earphone, and records the audio data in the recording unit of the external device. Therefore, the voice can be reproduced by transmitting the playback command by wireless communication from the photographing device without recording the voice data in the recording unit of the external device in advance.

Further, the photographing apparatus of this embodiment reproduces the voice that can be reproduced by the external device even if the voice command is transmitted before the transmission of the voice data is completed. Therefore, even if the condition for reproducing the audio data is satisfied before the transmission of the audio data is completed, the photographer can hear some audio.
