Description

  The present invention relates to an imaging device control technique.

  In recent years, network cameras have come to be used not only for monitoring purposes but also for various uses such as Web casting and TV conferences. As these network cameras, not only fixed cameras but also those that can be freely adjusted for pan, tilt and zoom have become widespread, and it is possible to adjust the shooting angle of the network camera from a remote location. .

  As a user interface (hereinafter referred to as UI) for adjusting a shooting angle, a UI for specifying a shooting angle from a panoramic image, a UI for specifying a shooting angle from a circular diagram, a UI for specifying a shooting direction with a scroll bar, and the like are known. ing. In addition, a technology that uses these UIs to improve user convenience is also disclosed.

  For example, Patent Document 1 discloses a method for simplifying and controlling a user's operation using a scroll bar corresponding to a movable range of a camera. Japanese Patent Application Laid-Open No. 2004-228561 discloses a method of intuitively controlling the relationship between the entire image and the partial display state by matching the aspect ratio of the entire image captured by the camera with the aspect ratio of the scroll bar.

  With the recent widespread use of network cameras, a wide variety of uses by users that have not been assumed in the past have emerged, and turning cameras that can rotate 360 degrees endlessly have been used.

  Camera control by UI using a scroll bar, which is an example of UI used for controlling the shooting angle of these turning cameras, will be described with reference to FIG. FIG. 10A shows a control screen before moving the shooting angle of the camera. In the viewer 1201, the subject 1207 is displayed in the center. Reference numeral 1202 denotes a scroll bar, which is moved by dragging and moving the scroll bar knob 1203 with a mouse to change the shooting direction of the camera to a desired direction. For example, when the knob 1203 is moved in the direction indicated by the arrow 1206 (right side), the subject 1207 moves to the left side of the viewer 1201 as shown in FIG. 10B, and the knob 1203 returns to the center from the dragged position.

  In the UI of such a turning camera, the movement amount of a UI using an arrow button is determined by the button click time or the like, and thus the movement amount cannot be intuitively grasped. In addition, a UI using a panoramic image has a large display size of the UI itself, which complicates the camera control screen.

  In addition, the UI using the scroll bar intuitively grasps the relative position before and after the change of the shooting angle because the knob of the scroll bar returns to the center after changing the shooting angle of the camera. I can't.

  Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. The embodiment described below shows an example when the present invention is specifically implemented, and is one of the specific examples of the configurations described in the claims.

[First Embodiment]
First, a configuration example of a system for controlling a turning imaging apparatus and viewing an image captured by the imaging apparatus will be described with reference to the block diagram of FIG. As shown in FIG. 1, the system according to the present embodiment includes a camera server device 100 and a client terminal device 120, and each device is connected to a network 130 such as a LAN or the Internet.

  First, the camera server device 100 will be described. The camera server device 100 captures an image at the pan angle requested from the client terminal device 120 and transmits the captured image to the client terminal device 120.

  The imaging unit 101 is a device that can capture moving images and still images. The imaging unit 101 has a circuit (not shown) for performing zooming, focusing, exposure, etc., and controls its own optical system according to an optical system control signal received from the lens control unit 108 via the slip ring 102 and is optimal. Take a good image. Then, the imaging unit 101 sends captured images of each frame and still images (hereinafter collectively referred to as captured images) to the slip ring 102.

  The slip ring 102 sends the captured image received from the imaging unit 101 to the video processing unit 103. Further, the slip ring 102 has a pan motor 111 for changing the pan angle of the image pickup unit 101, and the pan motor 111 changes the pan angle of the image pickup unit 101 in accordance with a control signal from the pan head control unit 109. Thereby, it is possible to change the pan angle of the imaging unit 101 in accordance with the control signal from the pan head control unit 109 and perform imaging at a desired pan angle.

  The video processing unit 103 performs various image processing on the captured image received from the imaging unit 101. Then, the video processing unit 103 sends the captured image that has undergone image processing to the encoding unit 104.

  The encoding unit 104 encodes the image-processed captured image received from the video processing unit 103 to generate encoded data. Examples of encoding methods include JPEG and H.264. Although there are methods such as H.264, this embodiment does not depend on a specific encoding method, and various encoding methods may be applied. Of course, the encoding process is not essential and may be omitted as appropriate. The encoding unit 104 stores the generated encoded data in a memory such as the RAM 107 or sends it to the communication unit 110.

  The CPU 105 controls the operation of each unit constituting the camera server apparatus 100 and executes processes described later as what the camera server apparatus 100 performs. The ROM 106 stores setting data and a boot program for the camera server device 100.

  The RAM 107 has an area for temporarily storing various data received from the client terminal device 120 via the communication unit 110, a work area used when the CPU 105 executes various processes, and the like. That is, the RAM 107 can provide various areas as appropriate.

  The communication unit 110 transmits and receives data to and from the client terminal device 120 via the network 130. For example, data transmitted from the client terminal device 120 via the network 130 is transferred to the RAM 107 via the communication unit 110. Stored. The encoded data generated by the encoding unit 104 is transmitted to the client terminal device 120 via the communication unit 110 and the network 130.

  In FIG. 1, the imaging unit 101, the slip ring 102, the pan motor 111, the lens control unit 108, and the pan head control unit 109 are shown as the configuration requirements of the camera server device 100. However, each may be an external device of the camera server apparatus 100, and some may be a single device.

  Next, the client terminal device 120 will be described. The client terminal device 120 designates a desired pan angle with respect to the camera server device 100, and receives and displays an image captured at the designated pan angle from the camera server device 100.

  The communication unit 121 transmits / receives data to / from the camera server device 100 via the network 130. For example, the change amount of the pan angle specified on the client terminal device 120 side is determined via the communication unit 121. 100 is transmitted. The captured image captured on the camera server device 100 side is received via the communication unit 121 and stored in the RAM 124.

  The CPU 122 controls the operation of the entire client terminal device 120 and executes each process described later as what the client terminal device 120 performs. The display IF (interface) 125 is used to connect the monitor 140 to the client terminal device 120, and images and characters displayed on the monitor 140 are sent to the monitor 140 via the display IF 125.

  The RAM 124 has an area for temporarily storing various data received by the client terminal device 120 via the communication unit 121, a work area used when the CPU 122 executes various processes, and the like. That is, the RAM 124 can provide various areas as appropriate.

  The ROM 123 stores setting data of the client terminal device 120, a boot program, and the like. The input IF 126 is used to connect the mouse 150 to the client terminal device 120, and an operation instruction by the mouse 150 is notified to the CPU 122 via the input IF 126.

  The monitor 140 is configured by a CRT, a liquid crystal screen, or the like, and can display a processing result by the client terminal device 120 as an image or a character. For example, the monitor 140 displays a GUI (graphical user interface) described later.

  The mouse 150 is operated by a user to operate a GUI described later. Note that a device used for an operation instruction to the GUI is not limited to the mouse 150, and other input devices such as a keyboard may be used.

  Next, a GUI for causing the camera server apparatus 100 to perform imaging at a desired pan angle will be described with reference to FIG. This GUI is displayed on the display screen of the monitor 140. The GUI operation is performed by the user using the mouse 150 or a keyboard (not shown), and the CPU 122 performs GUI display control according to the user operation.

  In the area 201, a decoded image obtained by the CPU 122 decoding the encoded data transmitted from the camera server device 100 is displayed. In FIG. 2, a subject (house) 207 is shown at the center of the decoded image. ing.

  The user can operate the mouse 150 to slide the slide unit 203 left and right (in a one-dimensional direction) within a range 202 (scroll bar) in which the slide unit 203 can slide. As a method of sliding the slide unit 203, for example, a method of dragging and moving the slide unit 203 using the mouse 150 is generally used, but the method is not limited to this method.

  When the user operates the mouse 150 to move the slide unit 203 to the right side, the CPU 122 detects this and instructs the camera server device 100 to move the imaging angle of the imaging unit 101 to the right side. For example, when the user operates the mouse 150 to move the slide unit 203 to the right as indicated by the arrow 206, the CPU 122 detects this and instructs the camera server device 100 to move the imaging angle of the imaging unit 101 to the right. Instruct. Thereby, the pan head control unit 109 of the camera server apparatus 100 controls the pan motor 111 of the slip ring 102 and changes the pan angle of the imaging unit 101 so that the imaging angle of the imaging unit 101 moves to the right side. Therefore, the subject 207 moves to the left in the area 201 as indicated by the arrow 208.

  On the other hand, when the user operates the mouse 150 to move the slide unit 203 to the left side, the CPU 122 detects this and instructs the camera server device 100 to move the imaging angle of the imaging unit 101 to the left side.

  Areas 204 and 205 are areas for inputting numerical values. More specifically, an area 204 is an area for inputting a lower limit value (change amount lower limit value) of the change amount with respect to the pan angle, and an area 205 is an upper limit value (change amount upper limit value) of the change amount with respect to the pan angle. It is an area for input. An area 204 is an area for inputting the amount of change designated to the camera server apparatus 100 when the slide unit 203 is slid to the left end (one end) of the range 202. An area 205 is an area for inputting a change amount designated to the camera server apparatus 100 when the slide unit 203 is slid to the right end (other end) position of the range 202.

  In FIG. 2A, −90 ° is input to the region 204 as the change amount lower limit value, and + 90 ° is input to the region 205 as the change amount upper limit value. In this case, however, the user can designate any change amount between −90 ° and + 90 ° to the camera server device 100 by sliding the slide unit 203 left and right using the mouse 150.

  Then, the CPU 122 designates, to the camera server device 100, a change amount that is equal to or greater than the change amount lower limit value and closer to the change amount lower limit value as the position of the slide unit 203 is closer to the left end position. Further, the CPU 122 designates a change amount that is equal to or less than the change amount upper limit value and closer to the change amount upper limit value to the camera server device 100 as the position of the slide unit 203 is closer to the right end position.

  However, the pan / tilt head control unit 109 of the camera server apparatus 100 controls the pan motor 111 of the slip ring 102 to change the pan angle of the imaging unit 101 by the amount of change designated by the client terminal apparatus 120.

  Arbitrary numerical values can be appropriately input in the areas 204 and 205 (however, a numerical value in the area 204 <0 and a numerical value in the area 205> 0). FIG. 2B shows a display example of the GUI when −150 ° and + 150 ° are input to the areas 204 and 205 in the GUI of FIG. In this GUI, when the user operates the mouse 150 to move the slide unit 203 to the right side as indicated by the arrow 209, the CPU 122 detects this and moves the imaging angle of the imaging unit 101 to the right side. Instruct 100. Thereby, the pan head control unit 109 of the camera server apparatus 100 controls the pan motor 111 of the slip ring 102 and changes the pan angle of the imaging unit 101 so that the imaging angle of the imaging unit 101 moves to the right side. Therefore, the subject 207 moves to the left in the area 201 as indicated by the arrow 210.

  Here, in the GUI of FIG. 2A, a change amount of −90 ° to + 90 ° can be specified, whereas in the GUI of FIG. 2B, a change amount of −150 ° to + 150 ° can be specified. Therefore, the amount of movement of the subject 207 (the length of the arrow 210) when the slide unit 203 is slid by Δ in the direction indicated by the arrow 209 is the same as that when the slide unit 203 is slid by Δ in the direction indicated by the arrow 206. It is larger than the moving amount of the subject 207 (the length of the arrow 208).

  Next, processing performed by the client terminal device 120 for designating a desired pan angle to the camera server device 100 will be described with reference to FIG. 3 showing a flowchart of the processing. 3 is performed by the CPU 122. A computer program and data for causing the CPU 122 to execute this process are stored in a memory such as the RAM 124. However, the CPU 122 reads out and executes the computer program and data from the memory, thereby executing processing in each step described below.

  First, in step S <b> 301, the CPU 122 displays the GUI illustrated in FIG. 2 on the display screen of the monitor 140. Since the initial values α and β (α <0, β> 0) are set in the region 204 and the region 205, respectively, the slide unit 203 sets an arbitrary value between α and β to the pan angle. It can be specified as the amount of change.

  Next, when the CPU 122 detects an input of a numerical value to the area 204 or the area 205, the process proceeds to step S303 via step S302, and when not detected, the process proceeds to step S304 via step S302.

  In step S303, the CPU 122 sets the numerical value input to the area 204 as the change amount lower limit value (first setting), and sets the numerical value input to the area 205 as the change amount upper limit value (second setting). ).

  In step S <b> 304, the CPU 122 acquires the current position of the slide unit 203 within the range 202. In step S <b> 305, the CPU 122 calculates the amount of change designated to the camera server device 100 using the numerical values input in the areas 204 and 205 and the current position of the slide unit 203 within the range 202.

  For example, assuming that the length of the range 202 (sliding direction) is L, the change amount lower limit value is α, the change amount upper limit value is β, and the distance from the left end of the range 202 to the current position of the slide unit 203 is l. The amount of change γ specified in can be obtained by calculating the following equation.

γ = {(L−l) × α + l × β} / L
Of course, each time the slide unit 203 is moved in this manner, the amount of change corresponding to the current position is not limited to being obtained in real time. You may make it match | combine by calculating | requiring quantity. According to this method, it is not necessary to obtain the amount of change in real time, and it is only necessary to acquire the amount of change associated with the current position in advance.

  In step S306, the CPU 122 transmits the change amount obtained in step S305 to the camera server apparatus 100 via the communication unit 121. Accordingly, since the pan angle change amount input to the camera server device 100 according to the user operation can be specified, the pan head control unit 109 causes the pan angle of the image pickup unit 101 to be set by the specified change amount. To change.

  In the above description, the change amount upper limit value and the change amount lower limit value are input in step S303. However, the present invention is not limited to this, and information corresponding to the shooting angle of the imaging unit 101 is input, or the default range is set using a pull-down menu or the like. It is possible to perform the same control by selecting.

  In the above description, the pan angle is described as the control target angle, but the tilt angle or the low angle (rotation angle) may be set as the control target angle. In that case, the slide part 203 is not limited to sliding left and right as shown in FIG. In any case, the above description applies to the control device that changes one of the pan angle, tilt angle, and low angle of the imaging device as the control target angle and changes the control target angle by the specified change amount. The present invention can be applied to an information processing apparatus that specifies an amount.

  In this information processing apparatus, a slide part that can slide in a one-dimensional direction is displayed on a display screen in accordance with a user operation. Then, the amount of change designated to the control device when the slide portion is slid to the position of one end of the slidable range of the slide portion is set as the change amount lower limit value. Further, the amount of change designated to the control device when the slide portion is slid to the position of the other end of the slidable range is set as the change amount upper limit value.

  Then, the closer the position of the slide part is to the position of the one end, the change amount closer to the change amount lower limit value and closer to the change amount lower limit value is designated to the control device. A change amount equal to or less than the change amount upper limit value and closer to the change amount upper limit value is designated to the control device.

  Thus, it will be understood from these descriptions that the present embodiment can be similarly applied regardless of whether the control target angle is a pan angle, a low angle, or a tilt angle. Of course, two or more of the pan angle, low angle, and tilt angle may be controlled separately, and in that case, the above description may be applied to each angle.

[Second Embodiment]
In the present embodiment, when the user releases the drag after dragging the slide unit 203 using the mouse 150, the slide unit 203 returns to the center of the range 202. Further, the marker is arranged at a position where the relative position with respect to the position of the slide part 203 that has returned to the central part becomes the relative position of the slide part 203 before the drag with respect to the position of the slide part 203 when the drag is released.

  As shown in FIG. 4, when the user releases the drag after dragging the slide unit 203 to the position 405 using the mouse 150, the CPU 122 returns the slide unit 203 to the center of the range 202 as indicated by an arrow. Further, the CPU 122 sets a marker as a history at a position where the relative position with respect to the position of the slide section 203 that has returned to the center is the relative position of the slide section 203 before the drag with respect to the position 405 of the slide section 203 when the drag is released. 401 is arranged.

  In the present embodiment, the client terminal device 120 performs processing in which steps S304 to S306 are replaced with the flowchart of FIG. 5 in the flowchart of FIG. In the following, differences from the first embodiment will be described, and description of similar parts will be omitted.

  In step S501, the CPU 122 acquires the current position of the slide unit 203 within the range 202, as in step S304.

  In step S502, when detecting the release of the drag, the CPU 122 calculates the amount of change designated to the camera server device 100 in the same manner as in step S305. In step S <b> 502, the CPU 122 returns the slide unit 203 to the center of the range 202.

  In step S503, the CPU 122 determines whether to display a marker as a history. Whether or not to display a marker as a history can be set in advance using a GUI or the like. As a result of the determination, the process proceeds to step S504 when displaying, and the process proceeds to step S505 when not displayed.

  In step S504, the marker as a history is displayed on the range 202 as described above. In step S505, the CPU 122 transmits the amount of change obtained in step S502 to the camera server apparatus 100 via the communication unit 121, as in step S306.

  In the present embodiment, a marker as a history is displayed in step S504. However, the relative angle is calculated from the home position determined from the mechanism of the drive unit of the imaging unit 101 and the distance moved by dragging the slide unit 203, and the home position is always displayed, so that the imaging before the movement is performed. The position of the part 101 can be intuitively grasped.

[Third Embodiment]
In the second embodiment, the slide unit 203 is returned to the center of the range 202 as soon as the release of the drag is detected. However, in this embodiment, the slide unit 203 is detected after a certain time has elapsed since the release of the drag was detected. Return 203 to the center of range 202.

  In the present embodiment, the client terminal device 120 performs processing in which steps S304 to S306 are replaced with the flowchart of FIG. 6 in the flowchart of FIG. In the following, differences from the first embodiment will be described, and description of similar parts will be omitted. Further, in the flowchart of FIG. 6, the process of displaying the marker as the history is not performed, but the marker as the history may be displayed in the same manner as in the second embodiment.

  In step S601, the CPU 122 acquires the current position of the slide unit 203 within the range 202, as in step S304. In step S602, when detecting the release of the drag, the CPU 122 calculates the amount of change designated to the camera server device 100 in the same manner as in step S305. In step S603, the CPU 122 transmits the amount of change obtained in step S602 to the camera server apparatus 100 via the communication unit 121, as in step S306.

  In step S <b> 604, the CPU 122 determines whether or not a setting is made in advance so that the slide unit 203 is returned to the center of the range 202 after a predetermined time has elapsed since the release of the drag is detected. As a result of this determination, if such a setting has been made in advance, the process proceeds to step S605, and if not, the process proceeds to step S606.

  In step S605, the CPU 122 counts a certain time. In step S <b> 606, the CPU 122 starts processing for returning the slide unit 203 to the center of the range 202.

  The “certain time” may be set by the user or may be determined in advance. Further, after the CPU 122 detects that the user has performed a click operation on the mouse 150, the process of returning the slide unit 203 to the center of the range 202 may be started.

[Fourth Embodiment]
In the present embodiment, in addition to the amount of change in the pan angle, the speed at which the pan angle is changed is also designated in the camera server device 100. The designated speed is the absolute value of the amount of change designated in the camera server device 100. Is switched according to whether or not is 360 ° or more.

  In the present embodiment, the client terminal device 120 performs processing in which steps S304 to S306 are replaced with the flowchart of FIG. 7 in the flowchart of FIG. In the following, differences from the first embodiment will be described, and description of similar parts will be omitted.

  In step S701, the CPU 122 acquires the current position of the slide unit 203 in the range 202, as in step S304. In step S <b> 702, when detecting release of the drag, the CPU 122 calculates the amount of change designated to the camera server device 100 in the same manner as in step S <b> 305. Then, the CPU 122 determines whether or not the calculated absolute value of the change amount is 360 ° or more. As a result of this determination, if the absolute value of the change amount is 360 ° or more, the process proceeds to step S703, and if the absolute value of the change amount is less than 360 °, the process proceeds to step S705.

  In step S705, the CPU 122 substitutes the variable γ calculated in step S702 into the variable D. In step S706, the CPU 122 sets a speed (first speed) at which the pan motor 111 changes the pan angle of the imaging unit 101 by the change amount D.

  On the other hand, in step S703, the CPU 122 obtains N rotation + D ° from the change amount γ calculated in step S702. For example, when γ = 750 °, 2 (= N) rotation + 30 ° (= D).

  In step S704, the CPU 122 sets a speed (second speed) at which the pan motor 111 changes the pan angle of the imaging unit 101 by the amount of change calculated in step S702. Note that the second speed is slower than the first speed.

  In step S <b> 707, the CPU 122 transmits the change amount and speed determined by the above processing to the camera server apparatus 100 via the communication unit 121. For example, when N rotation + D ° is obtained as the change amount, the pan / tilt head control unit 109 rotates the pan angle of the imaging unit 101 by N rotation + D °. The rotation speed at that time is the second speed. On the other hand, when the amount of change is D, the pan head control unit 109 rotates the pan angle of the imaging unit 101 by D °. The rotation speed at that time is the first speed.

  It should be noted that not only this embodiment but also other embodiments, the step size of the change amount may be increased as the slide portion 203 approaches the end of the range 202. For example, as shown in FIG. 8, even if the slide part 203 is slid by the same amount at each position in the range 202, the amount of change can be specified in 45 ° increments near the center, but as the end of the range 202 is approached, the change amount is 90 ° increments. , 180 ° increments, 360 ° increments can be specified.

  In this way, by assigning the amount of change nonlinearly as the end of the range 202 is approached, fine adjustments can be made when the movement angle is small, and rough changes can be made when the movement angle is large, such as multiple rotations. It becomes.

[Fifth Embodiment]
In this embodiment, when the absolute value of the change amount is 180 ° or more, the camera server device 100 is designated to rotate the pan angle in the clockwise direction or the counterclockwise direction.

  In the present embodiment, the client terminal device 120 performs processing in which steps S304 to S306 are replaced with the flowchart of FIG. 9 in the flowchart of FIG. In the following, differences from the first embodiment will be described, and description of similar parts will be omitted.

  In step S901, the CPU 122 acquires the current position of the slide unit 203 within the range 202, as in step S304.

  In step S902, when detecting release of the drag, the CPU 122 calculates a change amount γ designated to the camera server device 100 in the same manner as in step S305. Then, the CPU 122 determines whether or not the calculated absolute value of the change amount γ is 180 ° or more. If the absolute value of the change amount γ is 180 ° or more as a result of this determination, the process proceeds to step S903. If the absolute value of the change amount γ is less than 180 °, the process proceeds to step S906. When the process proceeds from step S902 to step S906, in step S906, the CPU 122 sets the change amount γ as the final change amount.

  On the other hand, in step S903, the CPU 122 determines whether or not the setting is made to rotate the pan angle of the imaging unit 101 in the same direction as the pan angle rotation direction represented by the sign of the change amount γ. As a result of this determination, if this setting has been made, the process proceeds to step S904. If this setting has not been made, the process proceeds to step S906.

  When the process proceeds from step S903 to step S906, in step S906, the CPU 122 sets (D-360) as the final change amount if γ> 0, and if γ <0, the final value is determined. (D + 360) is set as the amount of change.

  In step S904, the CPU 122 sets the change amount γ as the final change amount. In step S <b> 905, the CPU 122 transmits the change amount determined as the final change amount by the above processing to the camera server device 100 via the communication unit 121.

  As mentioned above, although each embodiment of the 1st-5th embodiment was described, a various deformation | transformation and change are possible within the range of the summary. Moreover, the embodiment which combined 2 or more among 1st-5th embodiment can also be considered.
