Description

  The present invention relates to an imaging system, and more particularly, to an imaging assistance for a camera when using an electronic device such as an audio player.

  Electronic devices to which a voice recognition function for causing a computer to recognize a human voice or the like has been developed have been developed. In recent years, in electronic devices such as smartphones, application operations are performed by voice recognition, and voice operations by voice (so-called voice support) have become widespread.

  When receiving audio support, it is generally desirable to use an audio output device that is worn directly on the ear, such as headphones, so that sound does not leak outside. Similarly, when listening to music outdoors, an audio output device such as headphones is generally used so as not to inconvenience people.

  However, when shooting using a headphone such as the above-mentioned voice support in camera shooting, it is preferable to acquire and record surrounding sound information, particularly the sound of the subject, simultaneously with the sound of the already reproduced sound flowing from the headphone.

  That is, in order to appropriately acquire all sound information, the photographer needs to pay attention to volume control such as sound generated from the camera body and sound control with already reproduced sound flowing from the headphones.

  Patent Document 1 discloses a technique for saving the trouble of adjusting the volume of the sound generated from the camera body. Specifically, when the eye sensor detects that the photographer's face or finger looking through the optical viewfinder has approached the eyepiece, the focus sound, shutter sound, warning sound, background sound, playback sound, etc. The sound is output at a low volume from the built-in speaker. On the other hand, a technique is disclosed in which sound is output at a high volume from a built-in speaker when it is not detected by an eye sensor. Thereby, when the photographer looks into the viewfinder, the volume of sound generated from the camera body can be suppressed without switching work.

JP 2010-26459 A

  However, the prior art disclosed in the above-mentioned Patent Document 1 is a proposal that saves the trouble of adjusting the volume of sound generated from the camera body, and information acquisition means for peripheral sounds such as voices produced by the subject to be photographed In addition, there is no disclosure regarding control of sounds of ambient sounds and already reproduced sounds. In particular, when a photographer takes a picture using headphones, it is difficult for the photographer to acquire external sound information such as a subject's voice or external sound, and there is a possibility that a photo opportunity will be missed.

  In particular, in a camera that takes a picture through a viewfinder such as a single-lens reflex camera, the field of view is limited, so it is more difficult to acquire external information including the subject. That is, it becomes difficult to match the subject's voice when changing the angle of view or the composition. In addition, the photographer cannot recognize sounds such as an ambulance or the like approaching from outside the field of view.

  Therefore, the object of the present invention has been made in view of the above, and in a situation where a photographer uses headphones such as voice support and music listening and looks into the viewfinder and performs photographing, An object of the present invention is to provide a photographing apparatus capable of photographing while appropriately acquiring both.

In order to achieve the above object, a photographing apparatus according to the present invention includes:
An imaging system comprising: a headphone; and an imaging device connected to be communicable, wherein the headphone includes reproduction means for reproducing sound, and the imaging device includes a finder having eyepiece detection means, A first sound collecting means for collecting external sound; and a transmission means for transmitting audio information to the headphones. The external sound collected from the sound collecting unit is transmitted to the headphones.

  According to the photographing apparatus of the present invention, in a situation where the photographer uses a sound reproducing device such as headphones and is looking through the viewfinder, both the reproduced sound from the headphones and the ambient sound in the environment are appropriately acquired. It becomes possible to shoot while.

Reference numeral 7 denotes an optical viewfinder for confirming a subject image. Reference numeral 17 denotes a power switch for switching the power of the camera 11 on and off.

  A mirror box is provided in the camera 11 to guide the photographic light beam that has passed through the photographic lens 103, and a mirror unit 60 is provided in the mirror box. The mirror unit 60 is composed of a main mirror and a sub mirror, and is held at an angle of 45 ° with respect to the photographing optical axis in order to guide the photographing light beam toward a penta roof mirror (not shown) inside the viewfinder 7. (Hereinafter referred to as a mirror down position) and a state where the mirror is held at a position retracted from the photographing light beam so as to be guided in the direction of the imaging unit 22 (hereinafter referred to as a mirror up position).

  An eyepiece detection sensor 14 (approach detection unit) is installed below the finder 7 having the eyepiece. The eyepiece detection sensor 14 detects the presence or absence of an object (target object) within a certain distance from the front surface. In the present embodiment, a general infrared sensor that senses infrared rays emitted from an object is used as the eyepiece detection sensor 14. By this infrared sensor, it is detected that the user brought his face close to look into the viewfinder 7. The eyepiece detection sensor 14 is not limited to an infrared sensor, and an optical sensor having a light emitting unit and a light receiving unit, an ultrasonic sensor, or the like can also be used.

  The built-in microphone 19 is a sound collection unit for recording ambient sounds. For example, when recording a moving image at the same time, or when recording a still image or recording a still image within a predetermined time immediately after recording a still image. The case where typical voice recording (so-called voice memo) etc. is performed is mentioned. The position of the built-in microphone 19 is desirably on the front side of the camera on the image sensor side so that the sound of the subject can be easily collected.

  The camera of the embodiment of the present invention is a digital camera that generates image information by photoelectrically converting a subject image using an image sensor such as a CCD or CMOS, and records the image information on an electronic recording medium such as an arbitrary memory. .

  FIG. 3 is a block diagram illustrating a configuration example of the imaging apparatus according to the embodiment of the present invention. FIG. 3A is a block diagram schematically showing the hardware configuration of the camera 11.

  The camera 11 includes a photographing lens 103 including a focus lens, a shutter 101, and an imaging unit 22 that includes a CCD, a CMOS element, or the like that converts an optical image into an electrical signal. The camera 11 also includes an A / D converter 23 that converts an analog signal output from the imaging unit 22 into a digital signal.

  The image processing unit 24 performs resize processing such as predetermined pixel interpolation and reduction and color conversion processing on the data from the A / D converter 23 and the data from the memory control unit 25. The image processing unit 24 performs predetermined calculation processing using the captured image data, and the system control unit 50 performs exposure control and distance measurement control based on the obtained calculation result. As a result, TTL (through the lens) AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-emission) processing are performed. Further, the image processing unit 24 performs predetermined calculation processing using the captured image data, and the system control unit 50 also performs TTL AWB (auto white balance) processing based on the obtained calculation result. .

  Output data from the A / D converter 23 is directly written into the memory 32 via the image processing unit 24 and the memory control unit 25 or via the memory control unit 25. The memory 32 stores image data obtained by the imaging unit 22 and converted into digital data by the A / D converter 23 and image data to be displayed on the TFT 12. The memory 32 has a sufficient storage capacity for storing a predetermined number of still images, a moving image and sound for a predetermined time.

  The memory 32 also serves as an image display memory (video memory). The D / A converter 26 converts the image display data stored in the memory 32 into an analog signal and supplies it to the TFT 12. Thus, the display image data written in the memory 32 is displayed by the TFT 12 via the D / A converter 26.

  As described above, the TFT 12 performs display according to the analog signal from the D / A converter 26. In this way, the digital data once A / D converted by the A / D converter 23 and stored in the memory 32 is converted into analog by the D / A converter 26 and sequentially transferred to the TFT 12 for display. Functions as an electronic viewfinder (through image display).

  The nonvolatile memory 56 is an electrically erasable / recordable memory. As the nonvolatile memory 56, for example, an EEPROM or the like is used. The nonvolatile memory 56 stores constants, programs, and the like for operating the system control unit 50. Here, the program is a program shown in a flowchart described later in the present embodiment.

  The system control unit 50 controls the entire camera 11. The system control unit 50 executes a program recorded in the nonvolatile memory 56. The system memory 52 uses a RAM, stores constants and variables for operation of the system control unit 50, and develops a program read from the nonvolatile memory 56.

  The system control unit 50 also functions as a display control unit that controls the display of the TFT 12 by controlling the memory 32, the D / A converter 26, the TFT 12, and the like.

  The system timer 53 measures the time required for various controls and the time of a built-in clock. The mode change switch 16 and the release button 3 input various operation instructions to the system control unit 50. The mode switch 16 switches the operation mode of the system control unit 50 to a still image recording mode, a moving image recording mode, a reproduction mode, or the like.

  As described above, the release button 3 is turned on when half-pressed to generate the signal SW1. The system control unit 50 starts operations such as AF (autofocus) processing, AE (automatic exposure) processing, AWB (auto white balance) processing, and EF (flash pre-emission) processing in response to the switch signal SW1. When it is fully pressed (shooting instruction), it is turned ON and a signal SW2 is generated. In response to the switch signal SW2, the system control unit 50 starts a series of photographing processing operations from reading a signal from the imaging unit 22 to writing image data into the recording medium 150.

  The power control unit 80 includes a battery detection circuit, a DC-DC converter, a switch circuit that switches a block to be energized, and the like, and detects whether or not a battery is attached, the type of battery, and the remaining battery level. Further, the power control unit 80 controls the DC-DC converter based on the detection result and an instruction from the system control unit 50, and supplies a necessary voltage to each unit including the recording medium 150 for a necessary period.

  The power supply unit 30 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, or an AC adapter. The interface 27 is an interface with a recording medium 150 such as a memory card or a hard disk. The recording medium 150 includes a recording medium such as a memory card, a semiconductor memory, a magnetic disk, and the like.

  Reference numeral 300 denotes a headphone as a head-mounted audio reproduction device worn by the photographer, 301 an audio output unit that outputs audio from the headphone, and 302 an audio control unit that controls the output audio. Here, the headphone includes an inner ear type (earphone). The audio output unit 301 is divided into a right ear audio output unit 301a and a left ear audio output unit 301b, and each output is changed according to sound quality and the like. Note that the sound reproducing device worn by the photographer may be earphones or the like as long as it outputs sound, instead of headphones.

  FIG. 4 is a diagram showing the relationship between the first and second electronic devices according to the embodiment of the present invention. FIG. 4A is a diagram showing the relationship between a camera and headphones that collect external sounds in the first electronic device (camera) according to the embodiment of the present invention, and FIG. 4B is a diagram of the embodiment of the present invention. It is a figure which shows the relationship of the camera, headphones, and smart phone which collect external sound with a 2nd electronic device (smartphone).

  Details of the relationship among the camera 11, the smartphone 200, and the headphones 300 shown in FIGS. 4A and 4B will be described with reference to the flowchart of FIG.

(First embodiment)
FIG. 1 is a flowchart illustrating an example of a photographing operation according to an embodiment of the present invention. The flowchart of FIG. 1 illustrates a processing procedure executed by the system control unit 50 controlling each processing block. This is realized by developing a program stored in a memory (ROM) of each system control unit in the memory (RAM) and executing it by the CPU.

  If the power switch 17 of the camera 11 is on, in step S150, it is determined whether the photographer communicates with the headphones 300 and the camera 11 or the smartphone 200 for use. The presence / absence of communication is determined by the system control unit 50 or the system control unit 204 via the headphone connection detection unit 20 of the camera or the headphone connection detection unit 203 of the smartphone that detects whether the headphones 300 are connected. As connection means to each of these, connection using a wired cord or wireless connection such as WIFI or BLUETOOTH (registered trademark) may be used.

  In step S151, it is determined whether the connection destination of the headphones 300 is the camera 11 or the smartphone, and if it is determined that the headphone 300 is used by communicating with the camera 11, the photographer determines whether or not the eyepiece detection sensor 14 has detected eyepiece detection in step S152. to decide. When the eyepiece is not detected, that is, during live view shooting without using the viewfinder 7, normal camera shooting is performed with the headphones 300 used (step S159). The normal camera shooting referred to here indicates shooting without sound control. On the other hand, when the eyepiece is detected, that is, when taking a picture through the viewfinder, the collection of ambient sounds is started using the built-in microphone 19 of the camera 11 and through sounds are sent from the audio output units 301a and 301b of the headphones 300. (Step S153). Thus, even when the photographer is using the headphones and looking through the viewfinder, the photographer can perform photographing based on ambient sounds, that is, sounds such as voices emitted from the subject. Furthermore, it is possible to recognize a sound approaching an emergency vehicle such as an ambulance from outside the shooting angle of view regardless of shooting.

  By the way, the impact sound between parts when the mirror unit 60 in the camera 11 reaches the mirror up position from the mirror down position and the impact sound between parts when the mirror unit 60 reaches the mirror down position from the mirror up position are generated. become.

  That is, in the above step S153, when the ambient sound is collected, if the driving sound in the camera is also collected at the same time, the photographer not only feels annoyed, but also the obstacle to hear the already reproduced sound flowing from the headphones. It can be.

  In step S154, it is determined whether the drive unit in the camera 11 in which the built-in microphone 19 is installed has started. For example, it is determined whether a drive start operation member such as the release button 3 is operated and an electrical signal for starting the drive of SW2 is received. When the release button 3 is operated and the electrical signal of SW2 is received, in step S155, the collection of peripheral sounds is ended (interrupted) using the built-in microphone 19 performed in step S153.

  As a result, it is possible to eliminate the impact sound generated by the collision of the internal parts of the camera 11 due to the operation of the mirror unit 60 generated in the camera 11, and the photographer does not feel inconvenience, such as the sound emitted by the subject. I can hear the sound.

  In addition, when the drive unit starts to be driven in step S154, the system control unit 50 of the camera 11 can change the speed of the drive unit to a low speed to reduce the impact strength between components and reduce the impact sound. Good. For example, in the case of the mirror unit 60, the normal shooting mode may be switched to the silent shooting mode when the release button 3 is operated and the SW2 electric signal is received. Alternatively, when the driving unit starts driving in step S154, the system control unit 50 of the camera 11 and the audio control unit 302 of the headphone 300 communicate with each other, and a through sound is generated at a low volume from the audio output units 301a and 301b of the headphone 300. It may be output.

  Thereby, the photographer can reduce the troublesomeness caused by the impact sound generated in the camera 11.

  Then, in the next step S156, when driving in the camera 11 is completed, the collection of ambient sounds from the built-in microphone 19 is started again, and through sounds are output from the audio output units 301a and 301b of the headphones 300 of the headphones 300 ( Step S157).

  On the other hand, if the driving in the camera 11 is not completed in step S156, that is, if it is continuously driven, it is generally maintained that no ambient sound is collected. For example, sound collection is not performed when the mirror unit 60 continues to be driven, such as continuous shooting. However, as an example, when long-time shooting is performed by changing the shutter speed, there is an interval in which the impact sound is generated by the mirror unit 60, and therefore it is desirable to construct a sequence for flowing through sound from the headphones. Specifically, the mirror unit 60 calculates the time from the time when the electrical signal of SW2 is received from the system control unit 50 to the time when it reaches the mirror up position and the time when it starts moving to the mirror down position. While is not driven, ambient sound is collected and through sound is sent from the headphones 300.

  In step S158, when shooting is finished, the control of the already played sound and the surrounding sound that have been played from the headphone 300 is finished. The end of shooting indicates, for example, the case where the power switch 17 of the camera 11 is switched off. Alternatively, when the playback image is displayed on the TFT 12, the system control unit 50 determines that shooting has been completed, and the control of the surrounding sound is ended.

(Second embodiment)
In step S151, it is determined whether the connection destination of the headphones 300 is the camera 11 or the smartphone 300, and if it is determined that the headphone 300 is used by communicating with the smartphone 11, the photographer detects whether the eyepiece is detected by the eyepiece detection sensor 14 in step S182. Judging. When the eyepiece is not detected, that is, during live view shooting without using the viewfinder 7, normal camera shooting is performed with the headphones 300 used (step S159). On the other hand, when the eyepiece is detected, that is, when taking a picture through the finder 7, the headphone 300 is used and the built-in microphone 201 of the smartphone 200 is used to start collecting peripheral sounds, and the headphone 300 outputs sound. Through sound is sent from the parts 301a and 301b (step S183).

  As a result, similar to step S153 of the first embodiment, even when the photographer is using the headphones and looking through the viewfinder, the photograph is taken based on the surrounding sound, that is, the sound of the subject. It can be performed. Furthermore, it is possible to recognize a sound approaching an emergency vehicle such as an ambulance from outside the shooting angle of view regardless of shooting.

  In addition, by collecting sound from the built-in microphone 201 of the smartphone 200, the impact sound generated in the camera 11 is not collected, but is generated in the first embodiment of collecting sound by the built-in microphone 19 of the camera 11. There is no annoyance.

  Then, the operation of collecting ambient sounds using the built-in microphone 201 of the smartphone 200 in step S183 and flowing through sounds from the audio output units 301a and 301b of the headphones 300 is repeated until the eyepiece is no longer detected (step S184). When the eyepiece is not detected, that is, when the photographer finishes looking through the viewfinder, the collection of the peripheral sound is ended using the built-in microphone 201 of the smartphone 200 (step S185).

  Subsequently, in step S158, when the shooting is finished, the control of the already reproduced sound and the surrounding sound reproduced from the headphone 300 is finished. For example, the case where the power supply 17 of the camera 11 is switched off is shown. Alternatively, when the playback image is displayed using the TFT 12, the system control unit 50 determines that the photographing is finished, and the control of the surrounding sound is finished.

  FIG. 5 is a diagram illustrating an example of a usage state of the imaging system according to the embodiment of the present invention. FIG. 5A is a diagram illustrating a state in which a photographer is performing live view shooting without using an eyepiece using the camera and headphones according to the embodiment of the present invention. FIG. 5B is a diagram illustrating a state in which the camera and headphones according to the embodiment of the present invention are used for eyepiece shooting. FIG.5 (c) is a figure which shows the state which carries out eyepiece using the camera and headphones of embodiment of this invention, and collects a surrounding sound with a smart phone.

  Reference numeral 501 denotes an already reproduced sound that has flown in the headphone 300 in advance, and reference numeral 502 denotes a peripheral sound that flows from the headphone 300 after eyepiece detection. The voice 501 flowing in advance is, for example, music such as BGM or voice support voice. The voice support voice is, for example, an assist function related to the use of a smartphone that provides guidance for camera shooting assistance such as a warning that the subject is out of focus, or notifies that a call has been received or received by e-mail.

  The state in which the eyepiece is not detected in FIG. 5A is a so-called live view shooting in which a shooting through image is adjusted in view angle using the TFT 12. In this state, even if the subject deviates from the angle of view, the field of view is not limited as long as the subject is not looked into the viewfinder, so normal camera shooting is performed by the operation of step S159 in FIG.

  On the other hand, in the state where the eyepiece is detected in FIG. 5B, the ambient sound 502 is collected from the built-in microphone 19 by the operation of step S <b> 153 in FIG. 1, and through sound is sent from the sound output units 301 a and 301 b of the headphones 300. At this time, the already reproduced sound 501 and the surrounding sound 502 are reproduced simultaneously. As a result, the mixed sound flows from the playback unit 301 of the headphones 300, and the photographer can take a picture while listening to the sound information of the subject, that is, the surrounding sound 502 while receiving music or voice support.

  In this state, when the release button 3 is pressed in the operation of step S154 in FIG. 1, the peripheral sound 502 is interrupted. The effect is as described above. Regardless of the mirror-up operation, the collection of ambient sounds is interrupted in the same manner as when detecting that an operation with an impact sound such as a strobe pop-up is activated in the camera 11. Further, if eyepiece detection is not performed even during voice control in the state of FIG. 5B, that is, if the state of FIG. And the camera changes to normal camera shooting with only the already reproduced sound 501 flowing.

  In the state where eyepiece detection is performed using a smartphone for sound collection in FIG. 5C, the peripheral sound 502 is collected from the built-in microphone 201 by the operation of step S <b> 183 in FIG. 1, and the sound output unit 301 a of the headphone 300 is collected. And 301b. At this time, the already reproduced sound 501 and the surrounding sound 502 are reproduced simultaneously. As a result, the mixed sound flows from the playback unit 301 of the headphones 300, and the photographer can take a picture while listening to the sound information of the subject, that is, the surrounding sound 502 while receiving music or voice support. Similarly to FIG. 5 (b), when suddenly the state shown in FIG. 5 (a) is suddenly detected, normal camera shooting is performed in which the collection of the peripheral sound 502 is necessarily ended and only the already reproduced sound 501 is played. Change to

  FIG. 6 is a diagram for explaining the prior art and the problems of the present invention. FIG. 6A is an explanatory view of a conventional problem, and FIG. 6B is an explanatory view of an effect according to the embodiment of the present invention. Reference numeral 601 denotes an angle of view seen when the photographer looks into the viewfinder 7, reference numeral 602 denotes a subject (dog) that makes a sound, and reference numeral 603 denotes a sound (scream) emitted from the subject (dog).

  In FIG. 6A, since headphones are worn and music such as BGM or voice support is received, even if the subject 602 generates sound, it is difficult to follow based on the sound information. . Specifically, even if the subject 602 makes a cry outside the angle of view that the photographer is viewing, the photographer cannot determine which side is outside the angle of view. That is, it is difficult to adjust the angle of view 601 in a timely manner, and there is a possibility that a decisive moment such as a photo opportunity will be missed. Furthermore, inability to hear the surrounding sound other than the sound of the subject may cause the car to approach you or not recognize a warning sound such as a siren.

  On the other hand, in the embodiment of the present invention shown in FIG. 6B, the photographer can hear the sound (dog cry) 603 emitted by the subject by the above-described operation of step S153 in FIG. It becomes possible to grasp from which direction the sound is heard. That is, as shown in FIG. 6B, the angle of view can be adjusted based on the dog's cry. As a result, even if the photographer loses sight of the subject, the angle of view can be instantaneously adjusted based on the sound 603 generated by the subject. At the same time, it is possible to hear surrounding sounds other than the sound of the subject, and it is also possible to recognize a warning sound such as a car approaching or a siren.
