[Modes for carrying out the invention]

[0009] The imaging apparatus and control method for each embodiment will be described below with reference to the attached drawings. I will reveal it.

[0010] <First Embodiment> Figure 1 shows the image captured by the imaging device placed at the broadcast site (shooting location) of the subject. This is a conceptual diagram showing how an image signal is transmitted to a broadcasting station via a network. Then, photographer 110, at the broadcast site, uses the imaging device 100 to photograph the subject, reporter 1 20 is being filmed. The captured image signal generated by the imaging device 100 is transmitted to the network 200. It is transmitted to broadcasting station 300 via [this method]. Captured image V100 is transmitted to broadcasting station 300. This shows one frame of the captured image signal. Network 200 is typically the internet It is.

[0011] The switcher installed within the broadcasting station 300 receives the captured images transmitted from the imaging device 100. The switcher receives the image signal. The imaging device located within the broadcasting station 300 is detecting the subject. The captured image signal, or the imaging device placed at another broadcast site, captures the subject. The camera may receive multiple captured image signals. The switcher then selects the received multiple captured image signals. The selected captured image signal is then broadcast as a television signal.

[0012] Radio tower 350 transmits radio waves based on television signals supplied from broadcasting station 300. The television receiver 400 installed in the home receives radio waves from the antenna 450. Based on this, the television signal is displayed as an image. The switcher receives a signal transmitted from the imaging device 100. If you select the captured image signal, the television receiver 400 will have the same captured image V100 signal. The image will be displayed.

[0013] Please note that the captured image V100 may be processed by broadcast station 300, such as by overlaying text overlays. However, the image displayed on the television receiver 400 and the captured image V100 are not exactly the same. Not limited to that. To make it easier to understand, Figure 1 shows the timing of transmitting the captured image V100 and Ignoring the timing difference with the television receiver 400 that displays the image, the captured image V The image displayed on device 100 and television receiver 400 are considered to be the same image.

[0014] Broadcast station 300 sends the image signal being broadcast as a return image signal via network 200. The image is then transmitted to the imaging device 100. The return image V300 is sent from the broadcasting station 300 to the imaging device 100. This shows one frame of the return image signal sent to 00. Here again, to make it easier to understand. Therefore, the time difference between the captured image V100 and the returned image V300 is ignored, and the captured image Image V100 and return image V300 are treated as the same image.

[0015] The imaging device 100 displays the return image signal on a monitor, which will be described later, allowing the photographer 1 to see the image. 10 broadcasts the image signal of the subject (reporter 120) being photographed by the imaging device 100. It is possible to confirm whether or not they are present.

[0016] Figure 2 shows a specific configuration example of the imaging device 100. Each part of the imaging device 100 is connected to the bus 20. Therefore, they are connected to each other. Lens 11 allows light from the subject to enter the image sensor 12. Lens 11 may include multiple lenses. Lens 11 is used as an imaging device. It has a removal button 11B for removing it from the housing of the unit 100. B has a locking mechanism, and the control unit 25 activates the locking mechanism and releases the lock. It is configured so that it can be done. When the release button 11B is pressed, the control unit 2 Section 5 may be structured to convey that fact.

[0017] The image sensor 12 is a CCD (Charge Coupled Device) or CMOS (Complementary Microwave Oscillator). It is an etal oxide semiconductor. The image sensor 12 captures images of the subject. A shadow image signal is generated and supplied to the image processing unit 15.

[0018] Battery 13 supplies power to various parts of the imaging device 100. It has a removal button 13B for removing 13 from the housing of the imaging device 100. Button 13B has a locking mechanism, and the control unit 25 activates the locking mechanism. It is configured so that the lock can be released. When the release button 13B is pressed... The control unit 25 is configured to receive this information.

[0019] Lock for lens 11 release button 11B and battery 13 release button 13B The mechanism and the configuration for engaging and disengaging the lock using the locking mechanism are particularly A configuration like that described in Patent Document 2 can be adopted. Any locking mechanism other than the locking mechanism is provided by the lens 11's release button 11B and the backing. This can be used as the locking mechanism for the detachable button 13B of the Teri 13.

[0020] The thermometer 24 measures the temperature inside the imaging device 100. The fan 14 controls the control unit 25. It rotates based on the instructions and cools the imaging device 100.

[0021] In addition to the captured image signal, the image processing unit 15 also receives the radio waves that the communication unit 19 receives from the broadcasting station 300. A turn image signal is supplied. The image processing unit 15 processes the captured image signal and the return image signal. The data is processed and supplied to monitor 21. Monitor 21 displays the captured image and the returned image. The monitor 21 is a touch panel. The recording and playback unit 17 is processed by the image processing unit 15. The captured image signal may be recorded on the recording medium 170. The recording medium 170 is, for example, It is a memory card composed of flash memory.

[0022] The microphone 22 and speaker 23 are built into the imaging device 100. 22 is for the cameraman 110 to transmit audio to the director and other staff of broadcast station 300. It is provided. Speaker 23 is for the cameraman 110 to hear the audio transmitted from the staff. It is provided for this purpose. The microphone 22 and speaker 23 are connected to the broadcasting station 30, where the photographer 110 is connected. Configure the call unit to communicate with staff member number 0.

[0023] The audio signal picked up by the microphone 22 is processed by the audio processing unit 16. 19 transmits the audio signal from microphone 22 to broadcasting station 300. Audio processing unit 16 The communications unit 19 receives and processes the audio signal received from the broadcasting station 300 and supplies it to the speaker 23. To give.

[0024] As shown in Figure 1, reporter 120 is holding microphone 122 and speaking. The Kurophone 122 is connected to the external input terminal 26 and receives the audio signal from the reporter 120. The signal may be supplied to the imaging device 100, or it may be supplied to the imaging device 100 wirelessly. The audio processing unit 16 processes the audio signal of the sound picked up by the microphone 22. Recording and playback Unit 17 may record the audio signal processed by the audio processing unit 16 onto the recording medium 170. .

[0025] The communications unit 19 transmits the captured image signal and audio signal when the subject is being filmed in video to broadcasting station 3 Send to 00.

[0026] The acceleration sensor 18 detects the acceleration of the imaging device 100 and the control unit 25 It supplies power to the accelerometer 18. In the first embodiment, the accelerometer 18 may be omitted.

[0027] The control unit 25 has a functional configuration consisting of a broadcast usage determination unit 251, a device setting unit 252, and It has a display control unit 253. The control unit 25 is a microcomputer or microprocessor It can be composed of sass.

[0028] Using the flowchart shown in Figure 3, the operation of the imaging device 100 of the first embodiment and the first implementation The processing performed by the control method of the imaging device executed in the imaging device 100 will be explained. Then, in step S11, the control unit 25 sends the captured image signal to the imaging device 100 The control unit 25 controls the return transmitted from the broadcasting station 300 in step S12. The imaging device 100 is controlled to receive an image signal.

[0029] In step S13, the control unit 25 (broadcast usage determination unit 251) determines the transmission image of the return image. It is determined whether or not an image is included. The transmitted image is the image sent by the imaging device 100 to the broadcasting station 300. This is the image of the transmitted captured image signal. The control unit 25 analyzes both the transmitted image and the returned image. By analyzing the data, it is possible to determine whether or not the transmitted image is included in the returned image. The control unit 25 performs pattern matching on the transmitted image and the returned image so that they are identical. The control unit 25 may determine whether or not to proceed. The control unit 25 uses the image history of the transmitted image and the returned image. A histogram is generated, and whether the two images match is determined by whether the image histograms are nearly identical. You may do so.

[0030] In other words, the broadcast usage determination unit 251 determines that its imaging device 100 has photographed the subject and broadcasts to the broadcasting station 30. Determine whether the captured image signal to be transmitted to 0 is currently being used for broadcast by broadcasting station 300.

[0031] If the returned image in step S13 contains the transmitted image (YES), the control unit 25( The device setting unit 252) changes the settings of the imaging device 100 and the lens 11 in step S14. And the replacement of battery 13 is set to be prohibited. The replacement of lens 11 and battery 13 is, This corresponds to a change in the state of the image device 100. If the return image does not contain the transmitted image, NO), the control unit 25 (device setting unit 252) sets the imaging device 100 in step S15. Set the settings to allow changes and replacement of lens 11 and battery 13.

[0032] Although not shown in Figure 3, the transmitted image is included in the return image in step S13. If so, the control unit 25 (display control unit 253) will use the captured image displayed on the monitor 21. It is preferable to display a message indicating that the image captured by the imaging device 100 is currently being used for broadcast.

[0033] In step S16, the control unit 25 determines whether or not the power to the imaging device 100 has been turned off. If the power is not turned off (NO), the control unit 25 returns the process to step S11, Repeat the process from step S11 onwards. If the power is turned off (YES), the control unit 25 will stop processing. Terminate.

[0034] Figure 4 shows that the return image includes the transmitted image, and the image captured by the imaging device 100 is emitted. This shows an example of an image displayed on monitor 21 when it is determined that the device is in use for transmission. The image processing unit 15 displays on the monitor 21 the captured image V100 with the return image V300 scaled down. The reduced-size return image V300s is superimposed as a sub-screen to display the image. Display control unit 25 3. For example, near the upper right corner of monitor 21, a message indicating that the captured image V100 is being used for broadcasting is displayed. Additional information 231, which includes the text "Currently in use for broadcasting," is displayed.

[0035] The display control unit 253, regardless of whether the captured image V100 is in use for broadcast, for example, For example, a setting menu button 232 is displayed near the lower left corner of the monitor 21. Imaging device 100 When the settings menu is not displayed on monitor 21, the photographer 110 presses the settings menu button. When touching n232, the display control unit 253 displays a setting menu on the monitor 21, as shown in Figure 5. Display -233. With setting menu 233 displayed on monitor 21, photographer 1 When 10 touches the setting menu button 232, the display control unit 253 displays the setting menu 233. Delete.

[0036] In the example shown in Figure 5, setting menu 233 is the compression code used when compressing and encoding the captured image signal. This menu allows you to select the encoding method and the bitrate for compression encoding. The setting menu 233 is a menu for selecting H.264 and H.265, and bitrate You can choose the bitrate from 670kbps, 1240kbps, 3200kbps, and 4600kbps. This includes the menu items.

[0037] The imaging device 100 uses H.264 as the compression encoding scheme and a bitrate of 1240k Assume that the capture image signal is generated by selecting bps. The image captured by the imaging device 100 is When in use for broadcasting, the control unit 25 (device setting unit 252) sets the compression encoding scheme and bit Set the rate setting to not allow changes. In Figure 5, the selected H.264 and H. All options except 1240kbps, which supports 264, are considered inactive, and the settings are... It cannot be changed.

[0038] According to the imaging device 100 and control method of the first embodiment, the broadcasting station 300 captures The image device 100 operates appropriately depending on whether or not it is broadcasting the image signal of the subject it is capturing. This is possible. Specifically, the image signal of the subject being photographed by the imaging device 100 is broadcast. If the camera is inside, the lens 11 and battery 13 cannot be replaced. Therefore, photographer 11 0 accidentally changes the state of the imaging device 100 by replacing the lens 11 or battery 13. This prevents interruptions in the video signal during broadcasting.

[0039] Furthermore, if the image signal of the subject being captured by the imaging device 100 is being broadcast, compression encoding is performed. The settings for the format or bitrate cannot be changed. Therefore, photographer 110 made a mistake. By changing one of the settings and modifying the settings of the imaging device 100, during broadcasting This can prevent the image from freezing.

[0040] <Second Embodiment> The imaging device 100 of the second embodiment is configured as shown in Figure 2. However, the acceleration sensor 18 can be omitted. In the first embodiment, the captured image V100 and Although the time difference with the return image V300 is ignored, in reality, the two are not time-sensitive. It is slightly out of sync. In the second embodiment, the captured image V100 and the returned image V300 are time-dependent. Even if the target is slightly off, there are fewer misjudgments, and it is important to check whether the sent image is included in the returned image. It is configured to determine this.

[0041] Using the flowchart shown in Figure 6, the operation of the imaging device 100 in the second embodiment, the second implementation The processing performed by the control method of the imaging device 100 is described in Figure 6. Then, in step S21, the control unit 25 sets a predetermined time. The predetermined time is the same as The time corresponding to the temporal difference between the frame, the captured image V100, and the return image V300. That is the case.

[0042] As an example, the control unit 25 can set a predetermined time as follows: 25 is a Pi based on ICMP (Internet Control Message Protocol) to broadcasting station 300. The timing from when an ng request is sent to when a Ping request is sent until a Ping response is received. The maximum delay time is determined by multiplying the time until the end by a correction factor. The control unit 25 determines the maximum delay time Set this as the predetermined time.

[0043] In step S22, the control unit 25 controls the imaging device 100 to transmit the captured image signal. Control. In step S23, the control unit 25 records the captured image signal onto the recording medium 170. The recording and playback unit 17 is controlled. In step S24, the control unit 25 receives from the broadcasting station 300. The imaging device 100 is controlled to receive the transmitted return image signal.

[0044] In step S25, the control unit 25 checks if the return image includes the transmitted image (captured image). Determine whether it is present or not. If the return image contains the transmitted image (YES), the control unit 25 In step S27, the settings of the imaging device 100 are changed, and the lens 11 and battery 13 are changed. Set the exchange to disallowed. If the return image does not contain the transmitted image (NO), the control unit In step S26, the return image is the above recorded on the recording medium 170. It determines whether any of the transmitted images (captured images) from up to a specified time prior are included.

[0045] Assuming the above predetermined time is the time of 10 frames, the control unit 25 will return the image The frame to be judged and the frames up to 10 frames prior recorded on the recording medium 170 You just need to determine whether or not it matches any of the other frames.

[0046] In step S26, the return image is set to reflect the time prior to a predetermined time recorded on the recording medium 170. If any of the transmitted images are included (YES), the control unit 25 in step S27 The settings of the imaging device 100 and the replacement of the lens 11 and battery 13 are set to be prohibited. The return image will contain any of the transmitted images recorded on the recording medium 170 up to a predetermined time prior. If no image is found (NO), the control unit 25, in step S28, the imaging device 100 Set the settings to allow changing settings and replacing lens 11 and battery 13.

[0047] In step S29, the control unit 25 determines whether or not the power to the imaging device 100 has been turned off. If the power is not turned off (NO), the control unit 25 returns the process to step S22, Repeat the process from step S22 onwards. If the power is turned off (YES), the control unit 25 will stop processing. Terminate.

[0048] According to the imaging device 100 and control method of the second embodiment, the first embodiment achieves the following In addition to the effect of the captured image V100 and the returned image V300 being out of sync in time, However, it can determine whether or not the sent image is included in the returned image with fewer misjudgments. Cut.

[0049] <Third Embodiment> The imaging device 100 of the third embodiment is configured as shown in Figure 2. However, the acceleration sensor 18 can be omitted. In Figure 1, the broadcasting station 300 is the imaging device 1 This shows an example where the frame of the captured image signal generated by 00 is broadcast as is. 300 is within the frame of the captured image signal taken by another imaging device of the subject, imaging device 10 In some cases, the frame of the captured image signal generated by 0 is reduced in size and superimposed as a sub-screen for broadcasting. ru.

[0050] In Figure 7, the broadcasting station 300 is configured such that an imaging device located within the broadcasting station 300 captures the subject. Within the frame of the captured image signal, the frame of the captured image signal generated by the imaging device 100 The television signal is broadcast by reducing the size of the main screen and superimposing it as a sub-screen. Therefore, broadcasting station 3 00 is a sub-image where a reduced image V100s, which is a scaled-down version of the captured image V100, is superimposed as a sub-image. The turn image V300 is transmitted to the imaging device 100.

[0051] Using the flowchart shown in Figure 8, the operation of the imaging device 100 of the third embodiment, the third embodiment The processing performed by the control method of the imaging device 100 is described below. Then, in step S31, the control unit 25 (broadcast use determination unit 251) determines the characteristic points of the captured image The feature points are extracted and recorded on the recording medium 170 or RAM (not shown). The control unit 25 extracts feature points from the captured image in each frame of the captured image signal.

[0052] Figure 9 conceptually shows the feature point cloud extracted by the control unit 25 from the captured image V100. The circles indicate feature points. The control unit 25 controls areas or subjects where the brightness changes significantly within the frame. The corners are extracted as feature points.

[0053] In step S32, the control unit 25 controls the imaging device 100 to transmit the captured image signal. Control. In step S33, the control unit 25 receives the return image transmitted from the broadcasting station 300. The control unit 25 (broadcast usage determination unit 251) controls the imaging device 100 to receive the signal. In step S34, feature points are extracted from the return image, and the extracted feature point set is stored in recording medium 1. The data is recorded in RAM (not shown) or 70. The control unit 25 records each frame of the return image. The feature points of the return image are extracted.

[0054] Figure 10 conceptually shows the feature point cloud extracted by the control unit 25 from the return image V300. The black circles indicate feature points. The control unit 25 controls areas where the brightness changes significantly within the frame or The corners of the subject are extracted as feature points.

[0055] In step S35, the control unit 25 determines that the feature point cloud of the return image is the same as the feature point cloud of the transmitted image. Determine whether the feature point cloud of the return image contains similar features. If the group includes a feature point cloud similar in shape (YES), the control unit 25, in step S36, the imaging device Set the 100 setting change and disable the replacement of lens 11 and battery 13. Return If the feature point cloud of the image does not contain a feature point cloud similar to the feature point cloud of the transmitted image (NO), then In step S37, section 25 changes the settings of the imaging device 100 and the lens 11 and battery. Set the exchange of Ri13 to allow.

[0056] In step S38, the control unit 25 determines whether or not the power to the imaging device 100 has been turned off. If the power is not turned off (NO), the control unit 25 returns the process to step S31, Repeat the process from step S31 onwards. If the power is turned off (YES), the control unit 25 will stop processing. Terminate.

[0057] According to the imaging device 100 and control method of the third embodiment, the first embodiment achieves the following In addition to the above effect, it also produces the following effect: The captured image signal generated by the imaging device 100 is emitted as is. In cases where the image is not transmitted but is superimposed as a sub-screen within the frame of another captured image signal, However, this is due to the replacement of the lens 11 or battery 13, and the change in settings of the imaging device 100. This can avoid the problem.

[0058] <Fourth Embodiment> The imaging device 100 of the fourth embodiment is configured as shown in Figure 2. The accelerometer 18 is required. The broadcasting station 300 captures the image generated by the imaging device 100. When an image signal is being broadcast, if the cameraman 110 suddenly moves the imaging device 100, viewers will not be able to see clearly. It feels good.
