<< First Embodiment >>
<Configuration of monitoring system according to the first embodiment>
The configuration of the monitoring system 1A according to the present embodiment will be described with reference to FIG. The surveillance system 1A includes a surveillance camera device 10 and a display device 20. The surveillance camera device 10 includes an image sensor 11, a video memory 12, a storage unit 13, a CPU 14, and a communication unit 15.

The image sensor 11 is an image pickup device composed of, for example, a CMOS (Complementary Metal Oxide Semiconductor) sensor or a CCD (Charge Coupled Device) sensor, and converts the light of a photographed subject into an electric signal. The video memory 12 is composed of, for example, VRAM (Video RAM) and stores video information to be processed.

The storage unit 13 has a divided information storage unit 131 and a magnification information storage unit 132. The division information storage unit 131 stores coordinate information indicating the position of each block area in the image information, which is preset in order to divide the image information to be processed into a plurality of predetermined block areas. The magnification information storage unit 132 stores preset information on the display magnification for each block area.

The CPU 14 has an image pickup information processing unit 141, a display information changing unit 142, and a transmission processing unit 143. The image pickup information processing unit 141 has an image pickup information storage control unit 141a and a moving object detection unit 141b. The image pickup information storage control unit 141a sequentially stores the image pickup information captured from the image sensor 11 in the image memory 12 as the image information to be processed. The moving object detection unit 141b detects a moving object portion such as a human being as an attention portion from the video information stored in the video memory 12.

The display information changing unit 142 has a division processing unit 142a and a display magnification changing unit 142b. The division processing unit 142a divides the image information to be processed in the video memory 12 into a predetermined plurality of block areas based on the information stored in the division information storage unit 131. The display magnification changing unit 142b changes the display magnification of the partial image information of each block area divided from the image information to be processed based on the information stored in the magnification information storage unit 132. Further, the display magnification changing unit 142b changes the display magnification so that the partial image information of all the block areas corresponding to one moving object portion is uniformly displayed at any of the display magnifications of the corresponding block area.

The transmission processing unit 143 has a coding processing unit 143a and a transmission control unit 143b. The coding processing unit 143a encodes the video information in the video memory 12 changed by the display information changing unit 142 for transmission processing. The transmission control unit 143b transmits the video information encoded by the coding processing unit 143a from the communication unit 15 to the display device 20. The display device 20 displays the video information transmitted from the surveillance camera device 10.

<Operation of monitoring system according to the first embodiment>
Next, the operation of the monitoring system 1A according to the present embodiment will be described with reference to FIGS. 2 to 8. In the present embodiment, the surveillance camera device 10 is installed so as to photograph a space having a long depth (for example, several tens of meters) from the front. As a result, the surveillance camera device 10 captures the subject at a position close to the shooting position and the subject at a position far from the shooting position in the same screen.

Further, in the divided information storage unit 131 of the surveillance camera device 10 in the present embodiment, the image information to be processed is divided into block areas of vertical 32 × horizontal 18 (A to R) = 576 as shown in FIG. Coordinate information indicating the position of each block area (A1, A2, A3 ... P32, Q32, R32) in the image information preset for this purpose is stored.

Further, the magnification information storage unit 132 stores information on the display magnification preset for each of these block areas. In the present embodiment, the magnification information storage unit 132 stores information on the display magnification set for each row in the vertical direction as shown in FIG. This display magnification is effectively set for the block area of all the horizontal columns corresponding to each row. The information of the display magnification of FIG. 3 is set so that the display magnification becomes higher as the position of the subject is farther from the shooting position in the image information.

When the operation of the surveillance system 1A starts, the surveillance camera device 10 starts shooting. The flow chart of FIG. 4 shows the process executed by the surveillance camera device 10 after the shooting is started. When shooting is started, the image sensor 11 converts the light of the subject into an electric signal at predetermined time intervals, and the image pickup information storage control unit 141a of the image pickup information processing unit 141 sequentially captures the converted signals at predetermined time intervals. Each of them is stored in the video memory 12 as video information (S1).

Next, the division processing unit 142a acquires the first image information D1 stored in the video memory 12 as a processing target, and obtains the image information D1 based on the information stored in the division information storage unit 131. It is divided into 576 block areas as in 2 (S2).

Next, the moving object detection unit 141b detects the moving object from the image information D1. Existing techniques can be used as a method for detecting a moving object from the image information D1. Here, it is assumed that two moving objects, a person X and a person Y, are detected by the moving object detection unit 141b, as shown in FIG.

The moving object detection unit 141b identifies the rectangular areas Xa of B1 to F15 as the block areas corresponding to the detected positions of the person X based on the information stored in the divided information storage unit 131. Further, the moving object detection unit 141b specifies the rectangular area Ya of O25 to Q31 as the block area corresponding to the position of the person Y.

Then, the moving object detection unit 141b displays the identification information B1 to F15 of the block area of the specified rectangular area Xa and the identification information O25 to Q31 of the block area of the rectangular area Ya as the display magnification of the display information changing unit 142 as the detection processing result of the moving object. It is sent to the change unit 142b (S3). Here, when the moving object detection unit 141b does not detect a moving object in the image information D1, the moving object detecting unit 141b sends information notifying that there is no moving object to the display magnification changing unit 142b as a result of the moving object detection process (S3).

Next, the display magnification changing unit 142b changes the display magnification of the partial image information corresponding to each block area of the divided image information D1 to a corresponding value based on the display magnification information shown in FIG. 3 (S4). ). By changing the display magnification, the position of the subject is far from the shooting position, and the image pickup information portion that is difficult to see can be enlarged to improve the visibility.

When the display magnification of the image information D1 is changed in this way, the display magnification differs between the feet and the head of the person X and the person Y, the shape is distorted, and appropriate monitoring processing may not be performed. Therefore, when the moving object is detected by the moving object detecting unit 141b (“YES” in S5), the display magnification changing unit 142b further changes the display magnification of the moving object portion. Specifically, the display magnification changing unit 142b first identifies the person X portion of the moving object portion as a processing target (S6), and is the smallest value among the display magnifications of the block areas B1 to F15 corresponding to the person X portion. (Here, the value 1.000 set in the block area of the first line) is acquired (S7). Then, the display magnification changing unit 142b changes the display magnification of all the block areas B1 to F15 corresponding to the person X portion to 1.000 (S8). By changing the display magnification in this way, it is possible to prevent the person X and the person Y from appearing unnatural due to distortion.

Further, the display magnification changing unit 142b changes the display magnification of the block area around the person X so that the closer it is to the person X portion, the closer the display magnification of the person X portion is to 1.000 (S9). For example, among the block areas A7 to R7 on the seventh line in the image information D1, B7 to F7 corresponding to the position of the person X has a display magnification of 1.000, and A7 and G7 to R7 have 1.156. If it is displayed as it is, the display magnification changes abruptly between F7 and G7, so that the feeling of discomfort becomes greater when visually recognizing it. Therefore, as shown in FIG. 6, the display magnification of the block areas G7 to R7 around the person X is changed to 1.000 as the display magnification of the person X part closer to the person X part, while maintaining continuity. Change to get closer. Alternatively, the display magnification of the block areas G7 to R7 may be changed so as to approach the display magnification of the person X portion 1.000 with a quadratic curve change while maintaining continuity. Alternatively, the display magnification of the block areas G7 to R7 may be changed so that the closer to the person X part, the higher the rate of change, and the farther away, the lower the rate of change, so that the display magnification of the person X part approaches 1.000. good. By changing the display magnification with a smooth change in this way, it is possible to reduce the sense of discomfort when the image information D1 is visually recognized. In addition, the display magnification of the block corresponding to the position of the person X is set to be larger than the display magnification of the surrounding block area, and even when the person X is enlarged, the display magnification is maintained to be continuous as described above. However, by changing the image information, it is possible to prevent the image information around the enlarged portion from being hidden due to the image information of the enlarged portion. Similarly, the display magnification of the block area vertically adjacent to the person X may be changed so that the closer to the person X part, the closer to the display magnification of the person X part is 1.000.

When the process of changing the display magnification for the person X part is completed, the display magnification changing unit 142b identifies the unprocessed person Y part as the next processing target (“YES” → S6 in S10), and corresponds to the position of the person Y. The minimum value 1.624 among the display magnifications of the block areas O25 to Q31 to be performed is acquired (S7). Then, the display magnification changing unit 142b changes the display magnification of all the block areas O25 to Q31 to 1.624 (S8). As a result, the person Y is displayed in a shape without distortion while being enlarged from the state before the display magnification is changed. Further, the display magnification changing unit 142b maintains the continuity of the display magnification of the block area around the person Y to the display magnification of the person Y portion of 1.624 as it is closer to the person Y portion, as in the case of the person X. Change so that it approaches with a smooth change (S9).

For example, as shown in FIG. 7, the display magnification of the block areas A28 to N28 around the person Y in the 28th column is set to 1.624 as the display magnification of the person Y is closer to the person Y, and the display magnification is smooth while maintaining continuity. Set to approach by change.

When the display magnification change processing for all the moving body portions is completed by the above-mentioned processing (“NO” in S10), the image processing for the image information D1 is completed. The surveillance camera device 10 executes the processes of steps S2 to S10 described above for all the image information in the corresponding video information (“NO” in S11).

When the processing for all the image information in the video information is completed (“YES” in S11), the coding processing unit 143a of the transmission processing unit 143 changes the video information in the video memory 12 by the display information changing unit 142. Is encoded for transmission processing. Then, the transmission control unit 143b transmits the video information encoded by the coding processing unit 143a from the communication unit 15 to the display device 20 (S12). The display device 20 displays the image information transmitted from the surveillance camera device 10.

An example of the displayed image information is shown in FIG. In the image information of FIG. 8, a place farther from the shooting position is enlarged than the image information of FIG. 5 before the display magnification is changed, and the person Y is also enlarged and displayed accordingly.

According to the first embodiment described above, it is possible to make it easier to see the hard-to-see part on the back side by enlarging the part where the position of the subject is far from the shooting position in the entire image information. Further, the desired part in the image information, for example, the moving object part located far from the shooting position is enlarged to improve the visibility, and the part is enlarged so that the hidden part does not occur. Can be done. At that time, with respect to the moving object in the image information, it is possible to prevent the entire moving object from appearing unnatural due to distortion.

In the present embodiment, the display magnification is changed so that the partial image information of all the block areas corresponding to the moving object portion is displayed at the minimum value of the display magnification of the corresponding block area, but the display magnification is not limited to this, for example. By displaying the maximum value 1.780, the person Y may be displayed larger.
Further, the block area corresponding to the moving body portion may be uniformly changed to the moving body portion at a magnification other than the corresponding block area. For example, the person Y may be displayed larger by setting the magnification of the block areas O25 to Q31 corresponding to the position of the person Y to the magnification of Q32 1.806.

<< Second Embodiment >>
In the first embodiment described above, a case has been described in which the image information to be processed is enlarged and displayed at a higher display magnification as the position of the subject is farther from the shooting position in the block area. However, when the display magnification in the image information is changed in this way, the end portion of the image information (photographed image information) before the change is out of the display area, and a portion that is not displayed occurs. As a result, the angle of view of the captured image information and the angle of view of the display information are different, and there is a problem that the image information of the portion that is not displayed cannot be monitored. Therefore, in the second embodiment described below, the desired portion in the image information is enlarged to improve the visibility while displaying all the image information in the angle of view without changing the angle of view at the time of shooting. The case will be described.

<Configuration of monitoring system according to the second embodiment>
Since the configuration of the monitoring system 1B according to the present embodiment is the same as the configuration of the monitoring system 1A described in the first embodiment, detailed description of the portion having the same function will be omitted. In the present embodiment, the display magnification changing unit 142b does not perform the display magnification changing process on the block area of the entire imaging information to be processed, but only on the block area corresponding to the detected moving object portion and the block area around it. Perform display magnification change processing.

<Operation of monitoring system according to the second embodiment>
Next, the operation of the monitoring system 1B according to the present embodiment will be described. Also in this embodiment, the surveillance camera device 10 is installed at the same position as in the first embodiment. Further, the same information as in the first embodiment is stored in the divided information storage unit 131 and the magnification information storage unit 132.

When the operation of the surveillance system 1A is started and the shooting is started by the surveillance camera device 10, the same processing as in steps S1 to S3 of FIG. 4 is executed. After the process of step S3 is performed, the process proceeds to step S5 without performing the process of changing the display magnification of the image information of each block area in step S4. After that, when it is determined that the moving object is detected in step S5 (the processing of steps S6 to S8 executed in "YES" of S5 is the same as the processing described in the first embodiment, so it is detailed. The explanation is omitted.

Next, in step S9, when the display magnification of the moving object is larger than 1.000, the display magnification of the block area around the moving object is set to a value smaller than 1.000, so that the angle of view of the image information to be displayed is changed to the moving object portion. The angle of view of the image information (imaging information) before enlargement (before change) of is set to the same range. Similar to the case described in the first embodiment, when the display magnification of the part corresponding to the person Y in the image information D1 is changed to 1.624, the display magnification of the block area around the person Y is smaller than 1.000. To.

Of the block areas (A25 to N25, R25, A26 to N26, R26 ... A31 to N31, R31) around the person Y in the horizontal direction, for example, the block areas A28 to N28 are shown in FIG. 9A. The display magnification of the block areas A28 to G28 far from the person Y remains 1.000, and the display magnification of the part close to the person Y (H28 to N28) is set to the display magnification (1.000) of the block areas A28 to G28 and the block area O28. Change smoothly while maintaining continuity so that it gradually approaches the display magnification (1.624) of Q28. For example, as shown in FIG. 9A, the display magnification of the portion close to the person Y (H28 to N28) has an extremum whose display magnification is lower than 1.000, and the integral value of the magnification of the same row is 1 ×. It may be changed so as to be the number of divisions. Alternatively, the display magnification of the block regions H28 to N28 may be changed in a quadratic curve while maintaining continuity. Alternatively, the display magnification of the block regions H28 to G28 may be continuously changed by a curve having an extreme value.

Further, as shown in FIG. 9B, the display magnification of the block area (A28 to H28) far from the person Y is set to be lower than 1.000, while the display magnification of the block areas I28 to N28 close to the person Y is set. , The person Y may be smoothly changed while maintaining continuity so as to gradually approach the display magnification (1.624) of the block areas O28 to Q28 of the person Y. In this case as well, the display magnification of the block areas A28 to N28 is changed in a quadratic curve while maintaining continuity, is continuously changed in a curve having an extremum, or the integral of the magnifications in the same row. The value may be continuously changed so as to be 1 × the number of divisions.

Similarly, for the block areas other than A28 to N28 in the block areas (A25 to N25, A26 to N26 ... A31 to N31) around the horizontal direction of the person Y, a part of the display magnification is changed from 1.000. Change smoothly while maintaining continuity while lowering the value.

Similarly, in the vertical direction, among the block areas (O1 to O24, O32, P1 to P24, P32, Q1 to Q24, W32) around the vertical direction of the person Y, for example, the block areas P11 to P28 are As shown in FIG. 10, the display magnification of the portion close to the person Y (P18 to P24) is made lower than 1.000, and is smoothly changed while maintaining continuity. By executing the processing in this way, it is possible to magnify the subject of a distant moving object and display it without changing the angle of view at the time of shooting while preventing the enlarged part from being hidden and hidden. can.

In the first and second embodiments described above, the display magnification information stored in the magnification information storage unit 132 of the surveillance camera device 10 is set for each row in the vertical direction, and the display magnification set in each row corresponds to each other. The case where it is valid for the block area of all columns is explained. However, the present invention is not limited to this, and different display magnifications may be set for each block area within each line.

For example, when the surveillance camera device 10 is installed so as to shoot from one end to the other end of a long corridor as shown in FIG. 11, the display magnification of the block area portion corresponding to the wall W on the back side is maximized. , The display magnification of other areas may be set so that the closer to this wall W, the closer to the display magnification of the wall W portion. For example, when setting the display magnification of each block area as shown in FIG. 12, the display magnification of the block area corresponding to the wall W (H25 to H27, I25 to I27, and J25 to J27 shown underlined) is set to the highest. Set. By setting in this way, it is possible to magnify and display a desired subject at a magnification corresponding to the distance from the shooting position in a space having various shapes.

Here, when the wall W portion is a portion with a high degree of attention, the angle of view of the image information to be displayed is expanded (changed) by setting the display magnification of the block area around the wall W to be lower than 1.000. The angle of view of the image information (imaging information) in the previous) may be set to the same range. Then, even when a moving object enters the imaging range, the image information portion of the block area of the moving object portion is appropriately enlarged as described above according to the position of the moving object, and the display magnification of the surrounding block area is increased. By setting it lower than 1.000, the angle of view of the image information to be displayed may be set to the same range as the angle of view of the image information before enlargement.

Further, in the first and second embodiments described above, the case where the function as an image processing device is mounted in the surveillance camera device of the surveillance system has been described, but the present invention is not limited to this, and the surveillance camera device in the surveillance system is not limited to this. It may be mounted on an external device. For example, a surveillance camera is equipped with an image sensor, a video memory, and a transmission processing unit, and an external device having a function of detecting a moving object from the image pickup information transmitted from the surveillance camera and changing its display magnification is installed. You may.

Further, in the first and second embodiments described above, the display magnification of all the plurality of block areas is changed by the minimum value of the display magnification of the plurality of block areas corresponding to the moving body portion in the imaging information. explained. However, the present invention is not limited to this, and the display magnification of all the plurality of block areas is unified by the average value or the maximum value of the display magnifications of the plurality of block areas corresponding to the moving object portion, or any value larger than the maximum value. You may change it as follows.

Further, in the first and second embodiments described above, a value calculated by a function is sampled in the magnification information storage unit 132 of the storage unit 13 as display magnification information of each block area according to the number of divisions of the block area. The table information of the discrete values may be stored, and the information of the corresponding display magnification may be recalled and used according to the detection of the moving object and its change. Further, the display magnification changing unit 142b of the CPU 14 may calculate the display magnification information by a function according to the detection of the moving object and its change.

Further, in the first and second embodiments described above, the case where the moving object detection process is used as the detection process of the portion of interest to be enlarged in the image information has been described, but the present invention is not limited to this, and the desired object detection process by AI is described. May be used, or a predetermined area may be used as the attention portion.
