(First embodiment)
Hereinafter, a surveillance camera that is an imaging apparatus according to the first embodiment of the present invention will be described. FIG. 2 is a block diagram showing the configuration of the monitoring camera 701. As shown in FIG. In the monitoring camera 701, the video input through the lens 201 is processed as a captured video (digital video data) captured by the imaging unit 203. The lens 201 is controlled by the lens control unit 202 so that the subject can be photographed with the parameter setting value of the optimum optical condition by focus, zoom control, iris adjustment, or the like. The captured video (digital video data) processed by the imaging unit 203 is input to the image processing unit 204. The image processing unit 204 can cut the input captured video (digital video data) at an arbitrary size or an arbitrary position in the digital video data. The image processing unit 204 can cut out a plurality of partial video data of arbitrary positions and sizes from the picked-up video (digital video data) simultaneously upon receiving a cut-out instruction. The partial video data cut out by the image processing unit 204 is input to the encoding processing unit 206 together with the digital video data before being output output from the imaging unit 203.

  The encoding processing unit 206 encodes the digital video data output from the imaging unit 203 and the partial video data output from the image processing unit 204.

  The image generation unit 205 generates image data such as a designated character or rectangle as an image that can be superimposed on the partial video data or the entire video data. Data generated by the image generation unit 205 is input to the encoding processing unit 206. The encoding processing unit 206 performs an encoding process on video data in which data input from the image generation unit 205 is superimposed on digital video data from the imaging unit 203 or partial video data from the image processing unit 204.

  The encoded video data is input to the distribution control unit 207, and the distribution control unit 207 distributes the encoded video data to a client (information processing apparatus) that has made a request (distribution request). The communication unit 208 controls data communication when transmitting the video data distributed by the distribution control unit 207 and receiving information from the client.

  Each block is connected by an internal bus 209, and operates in response to a control signal from the CPU 210. The RAM 211 is used as a buffer for temporarily storing video data in the processing sequence, and loaded with setting information and programs from the user in addition to the video data. Here, the setting information from the user includes an arbitrary size (size information) for the image processing unit 204 to cut out the partial video, and position information (position information). A specific example of the contents of the setting information will be described later with reference to FIG.

  Various programs for controlling the processing of the monitoring camera 701 are stored in the ROM 212. The activated program is loaded into the RAM 211, and the program loaded into the RAM 211 operates by being read from the CPU 210. The setting information from the user is temporarily stored in the RAM 211 and stored in the ROM 212 and becomes effective after restarting. When the setting information from the user stored in the RAM 211 is instructed by the CPU 210, the image processing unit 204 refers to the size information and position information included in the setting information. Then, based on the size information and the position information, the image processing unit 204 extracts partial video data having an arbitrary size and position from the digital video data (whole video data). The image generation unit 205 generates images such as characters and rectangles. The CPU 210 transmits information such as the position information and size information of the cutout of the image processing unit 204, the position information on which the image generated by the image generation unit 205 is superimposed, and the generation status of each distribution video to and from the client via the communication unit 208. Send and receive with.

The processing flow of the distribution control unit 207 when the setting information regarding the video data requested by the client is changed or updated will be described with reference to the flowchart of FIG. The distribution control unit 207 distributes the partial video data clipped at an arbitrary size and position by the image processing unit 204 to all clients that have requested distribution via the processing of the encoding processing unit 206. When distribution requests are received from a plurality of clients, the distribution control unit 207 distributes video data to each client in accordance with the timing at which distribution requests from the respective clients are received.

  The distribution control unit 207 manages the video data (partial video data) requested by the client, and determines whether there is a position change in the cut-out position from the digital video data (whole video data) (step S301). .

  If there is no position change (S301-No), the process proceeds to step S304. On the other hand, if it is determined in step S301 that there is a position change (S301-Yes), the position information stored in the RAM 211 is updated (S302). Next, it is determined whether there is a size change for the partial video data to be cut out (S304). If there is a size change (S304-Yes), the size information stored in the RAM 211 is updated (S305). On the other hand, if there is no size change in the determination in step S304 (S304-No), the process proceeds to step S306. It is determined whether the position information or the size information has been updated (S306). If no information update has occurred (S306-No), nothing is transmitted and there is an information update (S306-Yes). Update information is distributed (S307).

  Next, the relationship between the position and size of the partial video data in the digital video data (whole video data) will be described with reference to FIG. FIG. 1A is a diagram showing the arrangement relationship of partial video data in digital video data (whole video data). The entire video data A (101) is digital video data (entire video data) based on the maximum resolution captured by the imaging unit 203. The entire video data A (101) has a resolution represented by pixels having a width of 1920 and a height of 960, and has coordinates with the center position (x, y) as the origin (0, 0). As for the coordinate axis, the upper direction of the Y axis and the right direction of the X axis are positive with respect to the origin (0, 0), and the lower direction of the Y axis and the left direction of the X axis are negative.

  The cutout video data B (102) which is partial video data is represented by relative coordinates (−450, 200) (relative position information) up to the center position of the cutout video data B based on the origin of the whole video data A. The cut-out video data B is represented as a rectangle having a width of 480 and a height of 270. The clipped video data C (103), which is partial video data, is represented by relative coordinates (400, -500) (relative position information) up to the center position of the clipped video data C based on the origin of the entire video data A. The cut-out video data C is represented as a rectangle having a width of 240 and a height of 185.

  The position information set for each video data can be expressed as shown in FIG. The coordinates, width, and height of the entire video data A are represented by information 104. The absolute coordinate system of the reference whole image data A is represented by the angle of view of Pan and Tilt, and the center position (0, 0) is set as the origin (0 °, 0 °). A displayable horizontal angle of view of 50 ° is set in the Zoom indicating the angle of view, and a pixel value of width and height is set in the Resolution indicating the resolution.

  The position information of the cut-out video data B is represented by information 105. Since it is based on the whole video data A having the absolute coordinate position representing the angle of view, the same values as the whole video data A are set for the values of Pan, Tilt, Zoom, and Resolution. A (whole video data A) having an absolute coordinate system is set as relative information (relative) for specifying a video serving as a reference representing the relative relationship between the coordinate system of the cutout video data B and the absolute coordinate system. Has been. The coordinates of the relative position (relative position information) from the origin of the entire video data A to the center position of the cut-out video data B are represented by x and y, and the width and height of the cut-out video data B are represented by Resolution.

  The position information of the clipped video data C is represented by information 106. Since the position information is expressed based on the absolute coordinate system of the entire video data A as with the cut-out video data B, the same values as the entire video data A are set for Pan, Tilt, Zoom, and Resolution. Similarly to the cutout video data B, the relative information (relative) for specifying the reference video representing the relative relationship between the coordinate system of the cutout video data C and the absolute coordinate system is A having an absolute coordinate system. (Whole video data A) is set.

  The cut-out video data B and the cut-out video data C can be represented by relative positions with reference to the entire video data A based on relative information for specifying a reference video. Note that there is no restriction on the relationship between the clipped video data and the digital video data (whole video data) because the clipped video data can be cut out at any position and size as long as the clipped video data is within the maximum size of the whole video data.

  When the cutout position is changed for the cutout video data B and the cutout video data C, the values of x and y (position information) are updated (S302). When the size information is changed, the Resolution is updated (S305).

  When the relative position information about the position information and size information of each video data is changed by the processing shown in FIG. 3, the position information and size information are updated at the timing when the change occurs. When the monitoring camera 701 receives a distribution request for the clipped video and the information is updated, the update information is distributed to the requesting client.

  In addition to the cutout video data B and the cutout video data C, new cutout video data is acquired by changing the setting. When distribution of existing clipped video data being distributed is stopped or deleted, for example, information represented as INFO = B indicating clipped video data B and INFO = C indicating clipped video data C (FIG. 1B). )) Is deleted.

  A processing flow of the distribution control unit 207 when the setting is changed will be described with reference to FIG. The distribution control unit 207 always determines whether the clipped video data is being distributed (S401). When the distribution control unit 207 determines that the video is not being distributed (S401-No), the video data and the setting information regarding the video data are also unnecessary. The distribution control unit 207 discards the managed video data and setting information related to the video data (S408), and ends the process.

  If it is determined in step S401 that video is being distributed (S401-Yes), it is determined whether or not a certain period of time has elapsed since the information was previously distributed to the client (S402).

  When a predetermined time (threshold time) predetermined according to each client has passed (S402-Yes), the current latest information is distributed to each client (S403). When the predetermined time has not elapsed (S402—No), the distribution control unit 207 determines whether there is a change (addition or deletion) of settings regarding the currently distributed video data (S404). If there is a setting change, the setting information for the new cutout video data and the position and size of the cutout video data are updated (S405), and the updated information is distributed (S403). On the other hand, if it is determined in step S404 that there is no change (addition or deletion) of settings regarding the video data (No in S404), the position and size of the cutout video data being distributed have not been changed within a certain time after distribution. Is determined (S406). If the position and size of the clipped video data being distributed have been updated (S406-Yes), the relative position coordinates and size information are updated (S407), and the updated information is distributed (S403).

  If it is determined in step S406 that the position and size of the clipped video data being distributed have not been changed (S406-No), there is no need to update the information, so new update information is not distributed to the client. The process ends.

  Next, the relative relationship between a plurality of clipped video data will be described with reference to FIG. Position information set for each piece of cut-out video data will be described taking two pieces of cut-out video data B and C as an example of a plurality of pieces of cut-out video data.

  Information 501 in FIG. 5 indicates position information (absolute position information) of the cutout video data B. From the relative position coordinates based on the entire video data A, the absolute position information of the cut-out video data B in the absolute coordinate system of A is calculated. Since the reference of the position information is the absolute position information in the absolute coordinate system of the entire video data A, the positions of Pan = -11 ° and Tilt = 5 ° are from the origin (0 °, 0 °) of the entire video data A. The value calculated at the position. Since Zoom is calculated from the horizontal angle of view information by the ratio of resolution, if the video data A has a width of 1920 (pixels) and 50 °, the cut-out video data B has a width of 480 (pixels) and the horizontal angle of view is 12.5 °. It becomes.

  Information 502 in FIG. 5 indicates position information indicating the relative relationship of the clipped video data C with reference to the position information (absolute position information) of the clipped video data B. Since the position information (absolute position information) of the clipped video data B is used as a reference, the information of the clipped video data B is used for Pan, Tilt, Zoom, and Resolution.

  The relative information (relative) for specifying the reference video representing the relative relationship between the coordinate system of the cutout video data C and the absolute coordinate system of the cutout video data B is B (cutout video) having the absolute coordinate system. Data B) is set. To represent the position of the cutout video data C, x and y are indicated by the number of pixels, and Resolution-C sets the resolution of the cutout video data C.

  The application 704 of the client 703 (information processing apparatus) that has received the above information from the monitoring camera 701 can construct the positional relationship between the clipped video data B and C based on the resolution and the positional information. The application 704 can display the clipped video data B and C superimposed on the maximum size distribution video (whole video data A) using the positional relationship between the clipped video data B and C.

  In this embodiment, the position information has been described using Pan, Tilt, Zoom and resolution formats. However, even if the coordinate system can calculate the absolute position and the relative position, the position information may be represented by a range from the abstract value 0 to 1. good. The coordinate system is described with the center position of the image as the origin. However, if the positional relationship with each image can be expressed by a coordinate system that is handled only by a positive number with the upper left as the origin, or a completely different coordinate system, this coordinate system can be used. Embodiments of the invention can be applied.

  The flow of processing of the distribution control unit 207 when distributing the entire video data (basic video) that is the cut-out source and the cut-out video data will be described with reference to FIG. When a video data acquisition request is made, Pan, Tilt, and Zoom shooting positions (PTZ) of the monitoring camera 701 are acquired, and video information (digital video data) including the resolution of the entire video data (basic video) is acquired. (S601).

  The distribution control unit 207 sets Pan, Tilt, and Zoom of the shooting position of the monitoring camera 701 as position information (absolute position information) in the absolute coordinate system (S602). Next, it is determined whether or not clipped video data is being distributed (S603). When the cut-out video data is not distributed (S603-No) and only the whole video data (basic video) is sent, only normal position information is distributed (S614).

  On the other hand, if it is determined in step S603 that the cutout video is distributed (S603-Yes), the absolute position information of the cutout video data is acquired (S604). Further, the resolution and size of the clipped video data are acquired (S605), and information of the clipped video data is acquired.

  It is determined whether the entire video data (basic video) is distributed (S606). When the entire video data (basic video) is distributed (S606-Yes), the cut-out video data for the entire video data (basic video) is determined. Relative position information is calculated (S607).

  Relative information (relative) for specifying a reference video representing the relative relationship between the calculated relative position information and the absolute position information of the whole video data is used as whole video data (basic video) having an absolute coordinate system. ) Is set (S608). Relative position information, absolute position information, and relative information for specifying an image serving as a reference representing the relative relationship between the relative position information and the absolute position information are generated as distribution information (S613).

  On the other hand, if it is determined in step S606 that the entire video data (basic video) has not been distributed (S606-No), only the cut-out video data has been distributed. Since a plurality of clipped video data can be clipped and distributed simultaneously, it is determined whether a plurality of clipped video data is distributed (S609). When a plurality of cut-out video data is distributed (S609-Yes), priority is given to the video with the highest resolution from the plurality of cut-out video data or the cut-out video data closest to the origin coordinate in the absolute coordinate system. To choose. Then, relative position information of other clipped video data is calculated with reference to the absolute position information of the selected clipped video data having a high priority (S610).

  High-priority cut-out video data having an absolute coordinate system is set in the calculated relative position information and relative information for specifying the reference video (S611), and the process proceeds to step S613.

  In step S613, relative information for specifying relative position information, absolute position information, and a video that serves as a reference representing the relative relationship between the relative position information and the absolute position information is generated as distribution information (S613). If it is determined in step S609 that there is only one clipped video data (S609-No), the absolute position coordinates (x, y) of the clipped video data are set as absolute position information in the absolute coordinate system (S612). In step S614, the information generated in the previous steps S612 and S613 is distributed as position information.

  According to the present embodiment, the relative position information, the absolute position information, and the relative information representing the relative relationship between the relative position information and the absolute position information are distributed, so that the relative position of the cut-out video data in the entire video data can be increased. A superimposed display showing the positional relationship is possible.

Further, the relative position information of the clipped video data can be expressed based on the absolute coordinate system of the entire video data. Each clipped video data can be represented without depending on a plurality of coordinate systems. Therefore, even when a plurality of cut-out video data is included in the whole video data, the relative positional relationship of the cut-out video data in the whole video data without depending on the coordinate system of each of the plurality of cut-out video data it is possible to show the.

  In other words, by distributing information indicating the relative position and size with respect to the absolute coordinate system, the position and size of partial video data in the whole can be specified at the distribution destination without distributing partial video data each time a distribution request is made Providing a simple imaging technique.

Hereinafter, the surveillance camera according to the imaging apparatus of the second embodiment of the present invention will be described. FIG. 8 is a block diagram showing the configuration of the monitoring camera 701, which is different from the configuration of FIG. 2 in that a motor drive control unit 813 is added to the configuration of FIG. 2 described in the first embodiment. The description of the components having the same reference numbers as those in FIG. 2 is omitted. The motor drive control unit 813 receives operation information from the client 703 (information processing apparatus) which is an external device through the communication unit 208 under the control of the CPU 210. The motor drive control unit 813 controls the drive of the motor for changing the orientation of the Pan or Tilt monitoring camera 701 in accordance with the received operation information. The direction of the monitoring camera 701 is changed by the motor drive by the motor drive control unit 813. The video input through the lens 201 is changed according to the orientation of the monitoring camera 701. For this reason, the position information of the image processed by the image processing unit 204 and the image (superimposed image) generated by the image generation unit 205 can also be expressed by the angle of view using Pan and Tilt.

  With reference to FIG. 9, the flow of the process for setting the position coordinates of the superimposed image according to the second embodiment will be described. In step S901, it is determined whether the video data is being distributed. When the video distribution is not in progress (S901-No), the distribution control unit 207 distributes the encoded video data to the client having requested (distribution request) as the normal information distribution. (S909).

  On the other hand, if it is determined in step S901 that the video data is being distributed (S901-Yes), it is determined whether the image (superimposed image) generated by the image generation unit 205 is in the video being distributed. (S902). If the superimposed image is in the video being distributed (S902-Yes), the relative position information of the superimposed image is updated based on the video data relating to the video being distributed (S903).

  Next, the relative information (relative relevance) for specifying the reference video representing the relative relationship with the absolute position (absolute coordinate system) based on the video being delivered with the superimposed image as a reference is superimposed. The image position information is set (S904).

  In step S909, the relative position information updated in step S903 and the relative information (relative relationship) set in step S904 are distributed.

  On the other hand, if it is determined in step S902 that the superimposed image is not in the video being distributed (S902-No), it is determined whether information related to the superimposed image is distributed (S905). If the information related to the superimposed image is being distributed (S905-Yes), the relative position information of the superimposed image with the information related to the superimposed image as the absolute position is generated (S906). Relative position information includes relative information (relative relationship) for specifying a video that serves as a reference representing the relative relationship between information related to a superimposed image having an absolute position (absolute coordinate system) and the superimposed image. The position information of the superimposed image is set (S907).

  In step S909, the relative position information generated in step S906 and the relative information (relative relationship) set in step S907 are distributed.

  On the other hand, if it is determined in step S905 that information related to the superimposed image is not distributed (S905-No), the position information of the superimposed image is set as absolute position information (S908). In step S909, the absolute position information set in step S908 is distributed.

  Next, with reference to FIG. 10, a shooting movable range of the monitoring camera 701 and an image shot within the shooting movable range will be described. The surveillance camera 701 can change the shooting direction of Pan and Tilt by driving a motor. A photographing movable range of the monitoring camera 701 is indicated by 1011. The lens of the monitoring camera 701 is attached to the ceiling and faces the ground. The Pan direction has a movable range of + 180 ° to −180 ° as the x axis, and the Tilt direction has a range of + 10 ° to −90 ° as the y axis. The origin is the center position (0 °, 0 °).

  The maximum imageable range input from the lens 201 is represented by 1012. The position in the imageable range is an x-axis of −70 ° and a y-axis of −40 °, a rectangle represented by a width 1920 and a height 1080, and a Zoom value represented by a horizontal angle of view is 50 °. An entire image in the maximum imageable range 1012 is represented by an image A (entire image data). The cutout video data B (1013) is video data cut out from the video A (whole video data). Character information (date information 1014 and time information 1015) is superimposed on the cut-out video data B (1013) as an OSD (On Screen Display) image. The image generation unit 205 generates character information as an OSD. The date information 1014 is displayed at the upper left position of the cutout video data B (1013), and the time information 1015 is displayed at the lower right position of the cutout video data B (1013). By using the relative coordinates (relative position information) to the center position of the cutout video data B based on the video A (whole video data) of the photographing movable range having the absolute coordinate system, the position information of the cutout video data B is obtained. It can be expressed in an absolute coordinate system.

  The position information of the cutout video data B in FIG. 10 will be exemplarily described with reference to FIG. The position based on the absolute coordinate system of the cutout video data B (1013) is represented by information 1101. The position of the date information (1014) superimposed on the cut-out video data B (1013) is represented by information 1102, and the position of the time information (1015) is represented by information 1103. The superimposed position of the date information (1014) and time information (1015) in the cutout video data B (1013) is normalized from 0 to 99 with the upper left on the cutout video data B (1013) as the origin (0, 0). It is expressed as a value. As relative information for specifying a reference video, B (cutout video data B) having an absolute coordinate system is set in relative information (Relative) of date information (1014). The position of the date information (1014) is represented by the coordinates (0, 0) of the clipped video data B having the absolute coordinate system, and the superimposed character size is represented as Resolution = 40 × 7 according to the coordinate width. Relative information B (cutout video data B) for specifying a reference video is also set in the time information (1015). As the position of the time information (1015), the coordinate value (99, 93) at the lower right of the coordinates of the clipped video data B is set, and Resolution = 30 × 7 is set as the superimposed character size.

  The client 703 (information processing apparatus) receives the information 1101, 1102, and 1103 in FIG. The application 704 of the client 703 (information processing apparatus) determines the position and size of the image to be superimposed on the cutout video data B from the positional information and size information of the superimposed image and the relative information for specifying the reference video. .

  Then, the application 704 generates a UI while superimposing the image on the screen based on the position and size of the superimposed image.

  According to the above-described embodiment of the present invention, when the clipped video data B and the superimposed image are superimposed and displayed on the entire video data according to the distribution request, the clipped video data B and the superimposed image (OSD character information) are periodically displayed. May not be delivered.
