Further, for example, about one bump 509 may be provided for one output wiring described later. Therefore, the size of the bump 509 may be larger than the pitch of the PD 504. Further, a bump larger than the bump 509 corresponding to the pixel region may be provided in a peripheral region other than the pixel region where the pixels are arranged.

  The signal processing chip 511 has a TSV (silicon through electrode) 510 that connects circuits provided on the front and back surfaces to each other. The TSV 510 is preferably provided in the peripheral area. The TSV 510 may also be provided in the peripheral area of the imaging chip 513 and the memory chip 512.

  FIG. 4 is a diagram for explaining the pixel array and the unit group 131 of the imaging chip 513. In particular, a state where the imaging chip 513 is observed from the back side is shown. In the pixel area, 20 million or more pixels are arranged in a matrix. In the present embodiment, 16 pixels of adjacent 4 pixels × 4 pixels form one group. The grid lines in the figure indicate the concept that adjacent pixels are grouped to form a unit group 131.

  As shown in the partially enlarged view of the pixel region, the unit group 131 includes four so-called Bayer arrays composed of four pixels, ie, green pixels Gb, Gr, blue pixels B, and red pixels R, vertically and horizontally. The green pixels Gb and Gr have a green filter as the color filter 502 and receive light in the green wavelength band of incident light. Similarly, the blue pixel B has a blue filter as the color filter 502 and receives light in the blue wavelength band, and the red pixel R has a red filter as the color filter 502 and receives light in the red wavelength band. .

  FIG. 5 shows an equivalent circuit diagram of the pixel 150. Each of the plurality of pixels 150 includes the PD 504, the transfer transistor 152, the reset transistor 154, the amplification transistor 156, and the selection transistor 158. At least some of these transistors correspond to the transistor 505 in FIG. Further, the pixel 150 includes a reset wiring 300 to which an ON signal of the reset transistor 154 is supplied, a transfer wiring 302 to which an ON signal of the transfer transistor 152 is supplied, a power supply wiring 304 that receives power supply from the power supply Vdd, and a selection transistor 158. A selection wiring 306 to which the ON signal is supplied and an output wiring 308 for outputting a pixel signal are arranged. Hereinafter, each transistor will be described by taking an n-channel FET as an example, but the type of transistor is not limited thereto.

  The source, gate, and drain of the transfer transistor 152 are connected to one end of the PD 504, the transfer wiring 302, and the gate of the amplification transistor 156, respectively. The drain of the reset transistor 154 is connected to the power supply wiring 304, and the source is connected to the gate of the amplification transistor 156. The drain of the amplification transistor 156 is connected to the power supply wiring 304, and the source is connected to the drain of the selection transistor 158. The gate of the selection transistor 158 is connected to the selection wiring 306, and the source is connected to the output wiring 308. The load current source 309 supplies current to the output wiring 308. That is, the output wiring 308 for the selection transistor 158 is formed by a source follower. Note that the load current source 309 may be provided on the imaging chip 513 side or on the signal processing chip 511 side.

  FIG. 6 is a circuit diagram showing the connection relationship of the pixels 150 in the unit group 131. Note that reference numbers of the respective transistors are omitted for the sake of easy understanding of the drawings, but each transistor of each pixel in FIG. 6 has the same configuration and function as each transistor arranged at a corresponding position in the pixel 150 in FIG. .

  In the unit group 131 shown in FIG. 6, the pixels 150 having the same color filter 502 form a pixel group. Corresponding to the three types of RGB color filters 502 as shown in FIG. 4, eight pixels Gb1, Gb2, Gb3, Gb4, Gr1, Gr2, Gr3, and Gr4 form a G pixel group. Similarly, four pixels R1, R2, R3, and R4 form an R pixel group, and four pixels B1, B2, B3, and B4 form a B pixel group. That is, a pixel group is formed for each wavelength region that passes through the color filter 502.

  Here, the gates of the transfer transistors are commonly connected between a plurality of pixels included in each pixel group. Thereby, the gates of the transfer transistors are controlled all at once in the pixels belonging to the pixel group and independently between the pixel groups.

  In the example shown in FIG. 6, the gates of the transfer transistors of the pixels Gb 1, Gb 2, Gb 3, Gb 4, Gr 1, Gr 2, Gr 3, Gr 4 included in the G pixel group are connected to a common G transfer wiring 310. Similarly, the gates of the transfer transistors of the pixels R1, R2, R3, and R4 of the R pixel group are connected to a common R transfer wiring 312 and the gates of the transfer transistors of the pixels B1, B2, B3, and B4 of the B pixel group are common. Are connected to the B transfer wiring 314.

  Further, the source of the selection transistor is connected in common between a plurality of pixels included in each pixel group. The sources of the selection transistors of the pixels Gb 1, Gb 2, Gb 3, Gb 4, Gr 1, Gr 2, Gr 3, Gr 4 of the G pixel group are connected to a common G output wiring 320. Similarly, the sources of the selection transistors of the pixels R1, R2, R3, and R4 of the R pixel group are connected to the common R output wiring 322, and the sources of the selection transistors of the pixels B1, B2, B3, and B4 of the B pixel group are common. Are connected to the B output wiring 324.

  A load current source 311 is connected to the G output wiring 320. Similarly, a load current source 313 is connected to the R output wiring 322, and a load current source 315 is connected to the B output wiring 324. The reset wiring 326 and the power supply wiring 316 are common in the unit group 131. Further, 16 selection wirings 318 are arranged on a one-to-one basis for each pixel, and are connected to the gates of the corresponding selection transistors.

  In this way, a plurality of output wirings are provided for one unit group 131. However, since the imaging chip 513 is a back-illuminated type, the number of layers of the wiring 507 of the imaging chip 513 can be increased without reducing the amount of light incident on the PD 504, and the wiring can be routed without increasing the size in the surface direction. .

  In the present embodiment, since the image sensor 13 has the above-described configuration, imaging conditions such as a frame rate, a gain, and an accumulation time can be changed in each pixel group.

  Returning to FIG. 1, the back imaging unit 14 is a so-called out-camera, and is provided on the back side of the telephone device 10 as shown in FIG. Similar to the front imaging unit 12, the rear imaging unit 14 is an imaging element 113 (FIG. 10) that can control imaging conditions of the imaging lens and each pixel (pixel group) as disclosed in International Publication No. 2013/145553. Reference).

  The display 16 is, for example, a liquid crystal display. For example, an operation screen for the user to operate the telephone device 10, an information provision screen for providing information to the user, and a videophone screen when the user uses the videophone function Etc. are displayed.

  The speaker 18 is disposed, for example, on the upper side of the display 16 in FIG. 2A and outputs sound under the instruction of the control unit 30. The microphone 20 is disposed, for example, on the lower side of the display 16 in FIG. 2A and collects surrounding sounds.

  The touch panel 22 is assembled on the display 16 and receives various inputs from the user.

  The storage unit 23 includes, for example, a non-volatile flash memory, and stores various information such as an address book table and user schedule data in addition to various programs.

  The communication unit 24 communicates with other devices (for example, the telephone device 110) via a telephone line or the like. For example, a communication with the other telephone device 110, a videophone call, connection to the Internet, Internet Communication with other information processing apparatuses via the network is enabled.

  The control unit 30 includes a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), and the like, and controls the entire telephone device 10. In the present embodiment, for example, when the user uses a videophone and receives setting information from another device (for example, the telephone device 110), the control unit 30 and the front imaging unit 12 and // The imaging condition of the rear imaging unit 14 is set. For example, when the control unit 30 receives an input of setting information of another device (for example, the telephone device 110) from the user, the control unit 30 transmits the setting information to the other device via the communication unit 24.

(Telephone device 110)
As shown in FIG. 1, the telephone device 110 has the same configuration as the telephone device 10 described above. In FIG. 1 and the like, a code obtained by adding 1 to the hundreds of codes of each component of the telephone device 10 is adopted as a symbol of each component of the telephone device 110.

(Regarding the processing related to the telephone devices 10 and 110)
Next, processing at the time of a telephone call (videophone or voice call) between the telephone devices 10 and 110 will be described with reference to FIGS.

  FIG. 7 is a flowchart showing processing during a call between the telephone devices 10 and 110. In this description, a case will be described in which a call is transmitted from the telephone device 10 to the telephone device 110.

  In the process of FIG. 7, first, in step S <b> 10, the control unit 30 waits until the user of the telephone device 10 (user A) inputs information on the other party on the telephone device 10. In this case, the user A uses the touch panel 22 to input the other party's telephone number or to select the other party's information from the address book table. When the information of the other party is input from the user A, the process proceeds to step S12.

  If transfering it to step S12, the control part 30 will judge whether a telephone call system is a videophone. That is, it is determined whether or not the user A has selected the videophone call after inputting the information of the other party. If the determination in step S12 is negative, that is, if a voice call is selected, the control unit 30 proceeds to step S13. If transfering it to step S13, the control part 30 will transmit a telephone call request | requirement to the telephone apparatus of a telephone call partner. Here, it is assumed that the control unit 30 transmits a call request to the telephone device 110 used by the user B.

  On the other hand, in telephone device 110, control unit 130 stands by until a call request is received in step S110. Therefore, when step S13 is performed on the telephone device 10 side, the control unit 130 proceeds to step S112. In step S112, the control unit 130 displays a reception screen. As shown in FIG. 8A, the reception screen includes a telephone number, a user name, and a call start button of the telephone device that has transmitted the call request.

  Next, in step S114, the control unit 130 stands by until the call start button is pressed by the user B. When the call start button is pressed by the user B, the process proceeds to step S116, and the control unit 130 determines whether the call method is a videophone. If the determination in step S116 is negative, the process proceeds to step S118 to execute a call process. Note that on the telephone device 10 side, the telephone call processing in step S14 is executed at the same timing as that in step S118 on the telephone device 110 side. Note that the call processing in steps S118 and S14 is the same as the voice call processing between general telephone devices, and thus the description thereof is omitted.

  Thereafter, the control units 30 and 130 execute call processing until the user ends the call in the telephone devices 10 and 110 (for example, until the call end button on the display 16 or 116 is pressed). Then, at the stage where the call is terminated (S16, S120: affirmative), the control units 30 and 130 disconnect the communication (S18, S122), and terminate all the processes in FIG.

  On the other hand, if the determination in step S12 is affirmative, that is, if user A has selected videophone as the call mode, control unit 30 proceeds to step S20. In step S <b> 20, the control unit 30 displays a setting screen on the display 16. Specifically, the setting screen is a screen including setting contents and a call start button as shown in FIG. In the setting screen of FIG. 8B, for example, when setting information regarding imaging from a call partner is received in the case where setting by the other party is permitted (permitted / not performed), whether to permit the setting is selected. Can do. Further, in the face resolution (high / medium / low), when a face is included in the range captured by the telephone device 110 of the user B, the resolution of the area including the face can be designated. . In addition, whether or not to display an area other than the captured face can be selected for display other than the face (on / off), and display other than the face is not performed for face enlargement (on / off). In this case, it is possible to select whether or not to enlarge the face. Further, in the display (or not) of the character information, it is possible to select whether or not to display the content spoken by the user B as the character information by executing the voice recognition of the user B of the telephone device 110. Further, in the imaging unit (front / rear / both), in the telephone device 110, it is desired to see which captured image of the front imaging unit 112 and the rear imaging unit 114, or the captured images of both the imaging units 112 and 114 are combined. You can select whether you want to see the image.

  After displaying the setting screen as shown in FIG. 8B, the control unit 30 waits until the call start button is pressed in step S22. Then, when the user A makes a selection on the setting screen and presses the call start button, the control unit 30 proceeds to step S24.

  In step S <b> 24, the control unit 30 transmits a call request to the other party's telephone device (user B's telephone device 110). Thereafter, the control unit 30 stands by until a response is received from the telephone device 110 in step S26.

  On the other hand, on the telephone device 110 side, when the control unit 130 receives a call request (Step S110: Yes), Steps S112 and S114 are executed in the same manner as described above. In Step S116, it is determined whether or not the call method is a videophone. to decide. If the determination in step S116 is affirmed, the process proceeds to step S124, and the control unit 130 displays a setting screen. The setting screen in this case is the same as the setting screen shown in FIG. 8B, but a setting end button is provided instead of the call start button.

  In this setting screen, when the user B determines the setting contents and presses the setting end button (step S126: Yes), the control unit 130 executes a response process for the telephone device 10 in step S128. After executing this response process, the control unit 130 executes the subroutine of the videophone call process in step S130. On the other hand, when there is a response from the telephone device 110 side (S26: Yes), the telephone device 10 executes a subroutine of the videophone call processing in step S28.

  Details of steps S28 and S130 will be described below with reference to the flowchart of FIG. In addition, since each process of step S28 and S130 is the same process, it demonstrates here taking the process (step S130) by the control part 130 of the telephone apparatus 110 as an example.

  In the process of FIG. 9, first, in step S150, the control unit 130 receives setting information related to imaging (information input on the setting screen described in step S124) via the communication unit 124. Send to.

  Next, in step S152, the control unit 130 waits until setting information related to imaging is received from the telephone device 10, and proceeds to step S154 when it is received. In step S154, the control unit 130 determines whether the setting by the other party is permitted. That is, in the setting screen of FIG. 8B, it is determined whether or not “Yes” is checked in the setting (permitted / not allowed) of the partner (user A). If the determination is negative, the process proceeds to step S162. If the determination is positive, the process proceeds to step S156.

  When the process proceeds to step S156, the control unit 130 sets an imaging condition. For example, in the telephone device 10, when setting information as shown in FIG. 8B is input, the imaging condition is set so as to perform imaging according to the setting. In the case of FIG. 8B, since the “front imaging unit 112” is used as the imaging unit and the face resolution is set to “high”, the image sensor 113 of the front imaging unit 112 as shown in FIG. In each of the pixels, the imaging condition is set so that the resolution of the area (first imaging area) 113a capturing the face is higher than that of the other area (second imaging area) 113b. In this case, the control unit 130 makes the thinning rate of the first imaging region 113a smaller than the thinning rate of the second imaging region 113b. In addition, the frame rate of the first imaging area 113a can be made smaller than the frame rate of the second imaging area 113b.

  Next, in step S158, the control unit 130 executes imaging and face recognition. In this case, the control unit 130 performs face recognition from the imaging result and specifies a range including the face.

  Next, in step S160, the control unit 130 specifies a range in which the first imaging region 113a is set based on the face recognition result, and sets a thinning rate and a frame rate of the specified first imaging region 113a. Note that the position and size of the first imaging region 113a change following the movement of the face.

  Next, in step S162, the control unit 130 creates a screen to be transmitted to the telephone device 10 from the captured image based on the setting information, and starts transmission / reception of sound with the created screen. That is, a videophone call is started. Here, as shown in FIG. 8B, when the display other than the face is set to “OFF”, the face enlargement is set to “YES”, and the character information display is set to “YES”, the control unit 130 As a screen, a screen indicated by a symbol G in FIG. 11A is created and transmitted to the telephone device 10 (control unit 30). The character information “How are you?” Is a display of the result of the control unit 130 recognizing the voice of the user B. As the character information, information such as a call time and a call charge may be displayed.

  The control unit 30 that has received the screen G displays a videophone screen as shown in FIG. 11A. In addition to the screen G, the video phone screen of FIG. 11A is captured by the front imaging unit 12 of the telephone device 10 and is created by the control unit 30 (S162), the setting button, and the call end. Includes a button. Here, even when the face is enlarged and displayed as shown in FIG. 11A, if the face resolution is set to “high”, the face of the user B is clearly displayed on the display 16. be able to.

  In the setting screen of FIG. 8B, when the display other than the face is set to “No”, the face enlargement is set to “No”, and the character information display is set to “Yes”, The screen shown in FIG. 11B is displayed. Here, when the screens of FIG. 11A and FIG. 11B are displayed on the display 16, the control unit 130 uses the area other than the face (second imaging area) in the front imaging unit 112 of the telephone device 110. It may be set not to perform the imaging of 113b). However, in order to cause the first imaging region 113a to follow the movement of the face, imaging may be performed for a predetermined range around the first imaging region 113a. In this case, imaging may be performed with the resolution set lower than that of the first imaging region 113a within the predetermined range. As described above, the processing amount of the control unit 130 can be reduced by reducing the imaging range or reducing the resolution as necessary, so that the communication load, power consumption, battery consumption, and the like can be reduced. It becomes possible to plan.

  Further, in the setting screen of FIG. 8C, when the display other than the face is set to “Yes”, the face enlargement is set to “No”, and the character information display is set to “Yes”, The screen shown in FIG. 12A is displayed. Further, in the setting screen of FIG. 8B, when the display other than the face is set to “Yes”, the face enlargement is set to “No”, and the character information display is set to “No”, A screen shown in FIG. 12B is displayed on the display 16. Even in this case, the resolution of the face range can be increased when it is desired to clearly display the other party's face, so that the visibility and usability of the user can be improved. In addition, the processing amount of the control unit 130 can be reduced by reducing the resolution of the area other than the face (second imaging area 113b). When the frame rates of the first imaging area 113a and the second imaging area 113b are different, there is a case where imaging is not performed in the other imaging area at the timing when imaging is performed in one imaging area. In such a case, the captured image of one imaging region and the most recent captured image of the other imaging region may be synthesized.

  Also, in the setting screen of FIG. 8B, the display other than the face is set to “No”, the face enlargement is “Yes”, the character information display is “No”, and “Both” of the imaging unit is used. If so, the screen shown in FIG. 13 is created as a videophone screen and displayed on the display 16. In the screen of FIG. 13, an image I (landscape image around user B) captured by the rear imaging unit 114 and an image J (user B image) captured by the front imaging unit 112 are combined. Displayed with status.

  Returning to FIG. 9, after step S <b> 162, the control unit 130 determines whether or not the setting button has been pressed in step S <b> 164. User B pushes the setting button when he / she wants to change the setting. When the setting button is pressed in this way, the determination in step S164 is affirmed, and the control unit 130 displays a setting screen in step S166. The setting screen in this case is the same as in FIG. 8B, but it is assumed that a setting change button is provided instead of the call start button.

  When the user B changes the setting on this setting screen and presses the setting change button (S168: Yes), the control unit 130 transmits the changed setting to the telephone device 10 via the communication unit 124 in step S170. Next, in step S172, the control unit 130 determines whether or not the call end button has been pressed. If the determination in step S172 is negative, the control unit 130 returns to step S164.

  On the other hand, if the determination in step S164 is negative, that is, if the setting button is not pressed, the process proceeds to step S174, and the control unit 130 changes the setting information (user A changes the setting from the telephone device 10 side). It is determined whether or not the information is received. If the determination in step S174 is negative, the process proceeds to step S172. If the determination is positive, the process proceeds to step S176.

  When the process proceeds to step S176, the control unit 130 determines whether the setting by the partner is permitted in the setting. If the determination in step S176 is negative, the process proceeds to step S172. If the determination is positive, the process proceeds to step S178. When the process proceeds to step S178, the control unit 130 reflects the setting changed by the user A in the telephone device 10 (updates the setting information stored in the storage unit 123). Thereafter, the process proceeds to step S172.

  Thereafter, the processing / determination of steps S164 to S178 is repeated, and when the determination of step S172 is affirmed, the control unit 130 proceeds to step S180. In step S180, the control unit 130 disconnects communication (call) with the telephone device 10 and ends all the processes in FIGS. As described above, the processing of FIG. 9 is also executed in parallel in the telephone device 10 (S28).

  Note that the control unit 130 (30) may receive input from the user to the videophone screen via the touch panel 122 (22) while performing the processing of steps S164 to S172. That is, for example, when the touch panel 122 accepts an input by the user B (here, a pinch-out operation is taken as an example) on the screen of FIG. 12B, the pinched-out portion is enlarged and displayed. You may do it. In this case, the information that the pinch-out operation has been performed is transmitted to the control unit 130 of the telephone device 110 on the other side by the control unit 30 as in the case where the setting is changed (S166 to S170). What is necessary is just to make it the control part 130 of the other party produce a screen based on the information of the said pinch out operation | movement. For example, when the user designates a place where the brightness is changed, the place may be displayed brightly. In this case, the control unit 30 transmits location designation information to the counterpart control unit 130, and the counterpart control unit 130 sets the gain of the pixel (pixel group) that captures the designated location to other elements. Or the charge accumulation time of a pixel (pixel group) that captures an image of a designated location may be made longer than that of other elements. When the user inputs an instruction to brighten the entire screen, the control unit 30 transmits the instruction to the control unit 130, and the control unit 130 controls a flash device (flash) (not shown). You may make it light-emit.

  In the present embodiment, for example, when the user A is set not to permit the setting by the other party, the setting of the image of the user A transmitted to the user B is set on the same setting screen as in FIG. It is good also to do in. Thereby, the user A can customize the screen displayed on the telephone device 110 of the user B by himself / herself. For example, if the user A does not want to show his / her surroundings, the setting may be made so that the screen display as shown in FIG.

  As described above in detail, according to the first embodiment, the telephone device 110 is set from the imaging unit 112 or 114 having the first imaging region 113 a and the second imaging region 113 b and the counterpart telephone device 10. A communication unit 124 that acquires information, and a control unit 130 that sets at least one of the imaging condition of the first imaging region 113a and the imaging condition of the second imaging region 113b based on the setting information acquired by the communication unit 124; Therefore, the imaging condition in the telephone device 110 can be changed based on the setting information input by the user A who uses the other party's telephone device 10. As a result, the preference of the user A of the telephone device 10 that displays the image can be reflected in the image captured by the telephone device 110, so that the user-friendliness can be improved.

  In the first embodiment, the control unit 130 restricts the setting of the imaging condition based on the setting information based on the information set by the user B on the setting screen (FIG. 8B) (S154: No) in the case of). Thereby, the other party (user A) can be prevented from unilaterally changing the imaging condition of the telephone device 110 used by the user B.

  In the first embodiment, the communication unit 124 transmits the image captured by the imaging unit 112 or 114 to the telephone device 10, so that the user A can see an image reflecting his / her preference. .

  In the first embodiment, the telephone device 110 includes the front imaging unit 112 and the rear imaging unit 114, and the control unit 130 is imaged by both the imaging units 112 and 114 via the communication unit 124. The images can be combined and transmitted to the telephone device 10 (see FIG. 13). As a result, the user A can simultaneously view the images on the front side and the back side of the telephone device 110.

  In the first embodiment, the control unit 130 receives operation information (such as a pinch-out operation) that is transmitted to the telephone device 10 and input to an image displayed on the telephone device 10. Thus, the image reflecting the operation information input to the image can be transmitted to the telephone device 10.

  In the first embodiment, since the electronic device system 100 is a system that performs a videophone call between the telephone devices 10 and 110 having the same function, each of the user on the transmission side and the user on the reception side The other party's imaging unit can be set. However, the present invention is not limited to this, and the other party's imaging unit may not be able to be set in either one of the telephone devices.

  In the first embodiment, the case where the setting information of the videophone is input immediately before the start of the call has been described. However, the present invention is not limited to this, and the setting information may be input in advance. The control units 30 and 130 may store the setting information when the videophone is terminated in the storage units 23 and 123, and read the setting information stored when the next videophone call is performed. .

  In the first embodiment, the case where the control unit 130 of the telephone device 110 used by the user B performs voice recognition and character information display of the user B has been described. However, the present invention is not limited to this. The control unit 30 of the device 10 may perform voice recognition of the user B and display of character information.

  In the first embodiment, one telephone device may be an interphone indoor installation device, and the other telephone device may be an interphone outdoor installation device. In this case, setting information set by the user on the indoor installation device is transmitted to the outdoor installation device, and based on the setting information, the control unit of the outdoor installation device at least of the first imaging region and the second imaging region of the image sensor. One imaging condition may be changed. Thereby, the same effect as the first embodiment can be obtained.

  In the first embodiment, the videophone between the two telephone devices has been described. However, the present invention is not limited to this, and the present invention can also be applied to a videophone using a PC (Personal Computer) and a WEB camera.

<< Second Embodiment >>
Hereinafter, the second embodiment will be described with reference to FIGS.

  FIG. 14 shows an example of how the electronic device system is used in the second embodiment. As shown in FIG. 14, in the second embodiment, a videophone call is made between the telephone device 10 used by the user A and the telephone device 110 held by the user B and used by the user B to the user E. Shall be performed. That is, in the second embodiment, it is assumed that a videophone call is performed by one person vs. many people (one person versus four people in FIG. 14).

  In the second embodiment, basically the same processing as the processing in the first embodiment (FIGS. 7 and 9) is performed, but the contents of the setting information in each telephone device 10 and 110 are the same. Is different.

  FIG. 15A shows an example of a setting screen (step S20 in FIG. 7) displayed on the telephone device 10 used by the user A. In the setting screen of FIG. 15A, for example, when setting information related to imaging from a call partner is received when setting by the other party is permitted (permitted / not), whether to permit the setting is selected. Can do. In addition, regarding the face resolution (according to high / medium / low / distance), when a face is included in the range captured by the telephone device 110, the resolution of the area including the face is selected. Can do. Further, in the imaging unit (front / back / both), in the telephone device 110, which one of the captured images of the front imaging unit 112 and the rear imaging unit 114 is desired to be viewed, or the captured images of both imaging units 112 and 114 are synthesized You can select whether you want to see the image. In addition, when there are a plurality of partners (priority display / priority display), whether or not the priority is explicitly displayed when the partner telephone device 110 captures a plurality of people. Can be set. In addition, the priority person can select how to define the priority person (person on the front side / speaking person / selected person). Although not shown in FIG. 15A, other information such as a priority display method and whether or not to display character information may be set on the setting screen.

  In the telephone device 10, it is assumed that the user A has input setting information as shown in FIG.

  FIG. 15B shows an example of a setting screen (step S124 in FIG. 7) displayed on the telephone device 110 used by the users B to E. In the present embodiment, it is assumed that the user B of the telephone device 110 inputs setting information as shown in FIG.

  In the second embodiment, when a videophone call is started between the telephone device 10 and the telephone device 110, a screen as shown in FIG. In the screen of FIG. 17A, an image of the user A who uses the telephone device 10 is displayed, and face images of the users B to E who use the telephone device 110 are displayed in a frame of the same size. It has become so. In addition, as in the first embodiment (FIG. 11A), a setting button and a call end button are displayed on the screen of FIG.

  Here, as shown in FIG. 15A, a method of controlling the image sensor 113 by the control unit 130 when “according to distance” is selected as the face resolution on the setting screen will be described. For example, as indicated by a broken line in FIG. 14, when the rear imaging unit 114 of the telephone device 110 is imaging the users C to E, the imaging element 113 included in the rear imaging unit 114 includes a rectangular area including the user's face. (First imaging region) 113ac, 113ad, 113ae can be set. In this case, it is estimated that the larger the area is, the closer the distance from the telephone device 110 is, and the smaller the area is, the farther the distance from the telephone device 110 is. Therefore, in this embodiment, the control unit 130 lowers the resolution of the region as the size of the region is larger (the distance is closer), and the resolution of the region as the size of the region is smaller (the distance is longer). Set high. By doing in this way, even if each area (users C to E's faces) is displayed in the display frame of the same size as shown in FIG. Can be made uniform (almost uniform). In the front imaging unit 112, if the resolution of the first imaging area including the face of the user B is set according to the distance, the degree of sharpness of the face of the user B and the degree of sharpness of the faces of the users C to E Can be the same (substantially the same). Note that, similarly to the first embodiment, the control unit 130 can set the resolution of the area other than the face (second imaging area 113b) to be low or not perform imaging. Thereby, power consumption can be reduced.

  In the second embodiment, when a videophone call is started, the control unit 130 of the telephone device 110 creates a screen G ′ as shown in FIG. 17A and transmits it to the control unit 30 of the telephone device 10. (Step S162 in FIG. 9). Thereby, since a screen as shown in FIG. 17A is displayed on the display 16 of the telephone device 10, the user A can make a call while looking at the faces of the other users B to E. In this case, since each user's face is imaged with the resolution according to the distance from the telephone device 110, the user A can see the faces of the users B to E with uniform clarity.

  By the way, in the setting screen of FIG. 15A, it is assumed that “display priority” is selected by the user A when there are a plurality of opponents, and “front person” is selected as the priority. In this case, since the control unit 130 creates a screen G ″ as shown in FIG. 17B and transmits it to the control unit 30, the person on the front side (user B) is displayed on the display 116 from other users. In this case, the control unit 130 considers the size of the display frame for displaying the face and the distance between the face and the telephone device 110, so that each first imaging is performed. For example, the control unit 130 can set the resolution of each first imaging region so that the data amounts in the display frame for displaying the face all match. The sharpness of the face displayed in each display frame can be made uniform.

  Although depending on user settings, in the priority display, as shown in FIG. 18A, the priority display frame may be displayed with a thicker line than the other display frames. Further, in the setting screen of FIG. 15A, when the user A selects “speaking person” as the priority, the control unit 130 speaks based on the movement of each user's mouth. The person who is present may be specified, and the display frame of the specified person may be displayed with a bold line as shown in FIG. 18B, or may be displayed larger as shown in FIG.

  Further, for example, in the setting screen of FIG. 15A, when the user A selects “selected person” as the priority, the control unit 30 displays the user A on the screen of FIG. The information of the display frame touched by is acquired and transmitted to the control unit 130. In this case, the control unit 130 may create a screen preferentially displaying the touched display frame based on the received information and transmit the screen to the control unit 30.

  Further, for example, as shown in FIG. 19, the control unit 130 adds characters indicating which user is located on the front side of the telephone device 110 and which user is located on the back side of the telephone device 110. The screen may be transmitted to the control unit 30.

  Note that the control unit 130 may set the imaging condition so that the priority is imaged at a higher resolution (or higher definition) than the other users. Thereby, a user's facial expression with a high priority can be displayed more clearly than other users.

  As described above, according to the second embodiment, the same effect as that of the first embodiment can be obtained, and the control unit 130 can control each of the first imaging regions 113ac to 113ae according to the size of the first imaging regions 113ac to 113ae. Since the imaging condition of one imaging area is changed, appropriate display can be performed on the telephone device 10. In addition, since the control unit 130 changes the imaging condition of the first imaging area according to the size of the display frame for displaying the image of the first imaging area on the telephone device 10, it is appropriate to consider the size of the display frame. Imaging can be performed.

  In addition, the control unit 130 can determine the priority based on the state of the user (for example, speaking). Thereby, the user (for example, the user who is talking) of a predetermined state can be displayed conspicuously.

  In the second embodiment, the case where one priority is determined has been described. However, the present invention is not limited to this, and a plurality of priority may be determined. Further, priority order may be set for each user, and display according to the priority order may be performed. The priority can be determined based on the position and state of the user (speaking, loud voice, etc.), user input, and the like. The display in accordance with the priority order may include at least one of the size of the display frame, the display position of the display frame, and additional characters (numbers indicating the priority order).

  Also in the second embodiment, the screen created by the control unit 130 may be changed based on operation information on the touch panel 22 of the telephone device 10 as in the first embodiment. Further, based on operation information on the touch panel 22 of the telephone device 10, the control unit 130 may control the operation of a flash (not shown).

  In the second embodiment, the user's face and user information are registered in the storage units 23 and 123 in advance, and the user information is displayed on the screen based on the user face authentication result. May be. In this case, the priority order may be determined based on user information (for example, job title).

  In the second embodiment, the case where a videophone call is made by one to many people has been described. However, the present invention is not limited to this, and the present invention can also be applied to a case where a videophone call is made by many to many people.

<< Third Embodiment >>
Hereinafter, an electronic device system according to a third embodiment will be described with reference to FIGS.

  FIG. 20 shows an example of how the electronic device system according to the third embodiment is used. In the present embodiment, as shown in FIG. 20, the user A holding the telephone device 10 uses the telephone device 10 and the camera device 210 to participate in a conference held at a remote place.

  FIG. 21 is a block diagram showing the configuration of the electronic device system 1000 of this embodiment. As shown in FIG. 21, the electronic device system 1000 includes a telephone device 10 and a camera device 210. The telephone device 10 has the same configuration as in the first and second embodiments. The camera device 210 includes an imaging unit 212, a microphone 213, a speaker 214, a storage unit 216, a communication unit 218, and a control unit 230.

  The imaging unit 212 is fixed on the wall or ceiling of the conference room and images the conference room. The imaging unit 212 has the same configuration as the front imaging unit 12 and the rear imaging unit 14 of the telephone device 10. That is, the imaging unit 212 includes an imaging element that can control the imaging conditions of each pixel (pixel group) as disclosed in International Publication No. 2013/145553.

  The microphone 213 collects sound in the conference room. The speaker 214 outputs the voice of the user A collected by the microphone 20 of the telephone device 10. The storage unit 216 stores setting information input from the telephone device 10. The communication unit 218 communicates with the communication unit 24 of the telephone device 10 to exchange voice and images.

  The control unit 230 includes a CPU and the like, and controls the camera device 210 in an integrated manner.

  Next, processing of the electronic device system 1000 according to the third embodiment will be described. In the electronic device system 1000 of the present embodiment, the setting process shown in FIG. 22 and the conference process shown in FIG. 24 are executed.

(Setting process)
In the setting process of FIG. 22, in the image captured in the conference room (see FIG. 23A), the user A uses the telephone device 10 in advance to determine which range is the whiteboard and in which range the user sits. It is a process to set.

  In the process of FIG. 22, first, in step S <b> 200, the control unit 30 waits until there is a setting start request. In this case, when the setting start request is input from the user A, the process proceeds to step S202.

  In step S <b> 202, the control unit 30 receives a captured image of the camera device 210 and displays it on the display 16. For example, an image obtained by capturing the inside of the conference room as shown in FIG.

  Next, in step S <b> 204, the control unit 30 displays a whiteboard range designation request on the display 16. User A who sees this display designates a whiteboard range (range WB in FIG. 23B) in the image displayed on display 16. In this case, the user A can specify the range by tracing the outer edge of the whiteboard with the finger on the touch panel 22.

  Next, in step S206, the control unit 30 waits until the whiteboard range is designated, and when the range is designated by the user A, the control unit 30 proceeds to step S208.

  In step S <b> 208, the control unit 30 displays a user presence range designation request on the display 16. The user A who sees this display designates a range where the user will exist during the conference (ranges U1 to U4 in FIG. 23B) in the image displayed on the display 16. In this case, the user A can specify the range by touching the diagonal position of the rectangular range to be specified on the touch panel 22, for example.

  Next, in step S210, the control unit 30 waits until the user presence range is specified, and proceeds to step S212 at the stage specified by the user A.

  If transfering it to step S212, the control part 30 will transmit the range (WB, U1-U4) designated by the user A to the camera apparatus 210 (control part 230) via the communication part 24. FIG. In addition, if the control part 230 receives the designated range (WB, U1-U4), it will memorize | store the coordinate information in the memory | storage part 216. FIG.

  Thus, the setting process in FIG. 22 ends.

(Conference processing)
Next, the conference process will be described along the flowchart of FIG. In the process of FIG. 24, first, in step S300, the control unit 30 of the telephone device 10 stands by until a request for starting a video conference is input from the user A. To do.

  In step S <b> 302, the control unit 30 transmits a conference start request to the control unit 230 of the camera device 210 via the communication unit 24. Thereafter, the control unit 30 executes communication start processing in step S304.

  On the other hand, the control unit 230 of the camera apparatus 210 stands by until a meeting start request is received in step S400. Therefore, when step S302 is executed on the telephone device 10 side, the control unit 230 proceeds to step S402 and executes a communication start process.

  As described above, when communication between the telephone device 10 and the camera device 210 is established, the control units 30 and 230 start audio transmission / reception (steps S305 and S403). In this case, the control unit 30 of the telephone device 10 outputs the conference room side sound collected by the microphone 213 from the speaker 18, and the control unit 230 of the camera device 210 receives the user A's sound collected by the microphone 20. Audio is output from the speaker 214. On the camera device 210 side, in step S404, the control unit 230 starts capturing an image. Here, in image capturing, the control unit 230 sets the range WB, U1 to U4 designated by the user as the first imaging region, and an object that moves independently of the range WB, U1 to U4 (presenter P and The range including (estimated) is set as the first imaging area, the other range is set as the second imaging area, and the resolution of the first imaging area is set higher than the resolution of the second imaging area. As a result, the whiteboard, the users B to D, and the presenter P can be imaged with high resolution.

  Thereafter, in the camera device 210, in step S405, the control unit 230 corrects the distortion of the whiteboard range WB. Specifically, since the whiteboard range WB is usually often captured in a trapezoidal shape, the image is corrected so that the trapezoidal shape becomes a rectangular shape, and distortion is reduced.

  Next, in step S406, the control unit 230 generates a screen by combining the images of the respective ranges (the corrected range WB and the ranges U1 to U4) and the image of the presenter P, and the telephone device via the communication unit 218. To 10 control units 30. Thereafter, the control unit 230 repeats the processes of steps S405 and S406 at predetermined time intervals (for example, every frame) until the determination of step S408 is affirmed, that is, until communication is disconnected.

  On the other hand, after step S304, the control unit 30 of the telephone device 10 stands by until a screen is received from the camera device 210 in step S306. Therefore, at the timing when step S406 is executed by the control unit 230, the control unit 30 proceeds to step S308 and displays the received screen. The screen displayed here is, for example, a screen including a presenter P, users B to E, and a corrected whiteboard image as shown in FIG. Note that when displaying as shown in FIG. 25A, it is not necessary to image an area other than the first imaging area (or the area other than the first imaging area and its surroundings). Thereby, processing load and power consumption can be reduced.

  However, the screen is not limited to the screen of FIG. 25A, and based on the setting by the user A, for example, a screen as shown in FIG. 25B or FIG. 26 can be displayed. The screen shown in FIG. 25B is an enlarged screen showing images of the presenter P and the whiteboard. When displaying such a screen, it is preferable to set the resolution of the range where the presenter P is imaged and the range where the whiteboard is imaged among the imaging elements of the imaging unit 212 to be higher than the resolution of other ranges. .

  On the other hand, the screen of FIG. 26 is a screen that displays, as text data, the result of the character recognition performed by the control unit 230 in the whiteboard image in the screen of FIG. By recognizing the characters written on the whiteboard and displaying them as text data, the content written on the whiteboard can be displayed in an easy-to-read manner. FIG. 26 shows a state in which user B is not displayed because the range U1 in FIG. 23B is not designated in the setting process.

  Next, in step S310, the control unit 30 determines whether or not there is a termination request from the user A. If the determination here is negative, the control unit 30 returns to step S306. And the control part 30 repeats the process and judgment of step S306-S310 until the completion | finish request | requirement from the user A exists.

  Thereafter, when there is a termination request from the user A, the determination in step S310 is affirmed, so the control unit 30 disconnects communication and terminates all the processes in FIG.

  As described above in detail, according to the third embodiment, the resolution of the range where the users B to D set by the user A will exist and the range where the whiteboard is imaged (first imaging region) Is set to be higher than the resolution of the other (second imaging region), so that the region desired by the user can be clearly displayed.

  Further, when imaging a wide range as in a conference room, the imaging unit 212 may have a wide-angle lens. In particular, in the region outside the optical axis, the image is distorted due to the curvature of the lens, but the distortion can be reduced by correcting the image as in the third embodiment. In this case, when a character is included in the corrected range, the character can be displayed in an easy-to-read manner.

  In the third embodiment, the imaging conditions may be individually set for the ranges WB and U1 to U4. In the setting process, a range that is not desired to be captured may be set for security reasons. If the presenter P does not exist in the conference, the face of the person who is speaking may be displayed larger.

  In the third embodiment, a monitor may be provided in the conference room, and the monitor and the camera device 210 may be connected. In this case, the control unit 230 may receive an image captured by the front imaging unit 12 and / or the rear imaging unit 14 of the telephone device 10 from the control unit 30 and display the image on the monitor.

  In the third embodiment, the camera device 210 may be another device (for example, a PC or a smartphone) that includes an imaging unit.

  In the third embodiment as well, as in the first embodiment, the contents spoken by the presenter may be displayed as text. Further, face recognition processing may be performed from images of presenters and conference participants, and the name, title, and the like may be displayed together with the images.

  The above-described embodiment is an example of a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention.
