The video signal of high definition.
Monitor recorder 11 is connect with multiple surveillance cameras 12 that each floor is arranged in.From each surveillance camera 12 to prison
Send captured image depending on logger 11, multiple surveillance camera images are arranged in monitor recorder 11 it is latticed,
And it is exported as a video signal.
The output of monitor recorder 11 is shown in FIG. 2 to the example of the image of image display 10.In Fig. 2, image
Resolution ratio be 1920 points × 1080 points of full HD size, be divided into 16 regions.Each image that segmentation obtains is set as
" V1 "~" V16 ".Due to carrying out the quartering respectively in length and breadth for full HD, thus the resolution ratio of each image become 480 points ×
270 points.
Back to Fig. 1, the building that the elevator controlling portion 13 of the operation control of elevator (not shown) will stop elevator is carried out
The information such as the information of layer and/or traffic direction (up and down direction) are sent to image display 10.Monitor 14 is shown from image
The image that display device 10 exports.
Image display 10 is built-in with the memory 101 for temporarily saving image data.Image inputs cutting part 102 and inputs
The image of the multiple surveillance cameras 12 sent from monitor recorder 11 is shown obtained on a picture image (for example,
Image shown in Fig. 2), and it is divided into each image, as in segmentation video signal write-in memory 101.
The range of each image of " V1 "~" V16 " for the image that slave monitor recorder 11 as shown in Figure 2 inputs can
It is determined with coordinate.
For example, Fig. 3 is for Fig. 2 shows the figures of coordinate, when (0,0) is in the upper left for setting image entirety, upper right is
(1919,0), lower-left are (0,1079), bottom right is (1919,1079).The resolution ratio of each image is 480 points × 270 points, thus example
As the image of " V1 " of Fig. 3 becomes the region impaled by (0,0), (479,0), (0,269), (479,269) this 4 coordinates.
Equally, " V2 "~" V15 " is also determined with coordinate, image inputs cutting part 102 will be from prison using coordinate
The Image Segmentation of the input of logger 11 is regarded as each image, as in segmentation video signal write-in memory 101.
In addition, the case where segmentation number for illustrating the image sent from monitor recorder 11 as an example is 16, however work as
It can also be so split with other segmentation numbers such as being divided into 4 parts or being divided into 9 parts come specified coordinate.
Each floor image corresponds to table storage unit 103 when segmentation is from the image that monitor recorder 11 inputs, and stores each segmentation
Video signal correspond to which floor surveillance camera 12 image, each floor image shown in Fig. 4 correspond to table.
That is, image " V1 "~" V16 " shown in Fig. 2 shows the segmentation video signal of the image inputted from monitor recorder 11
Region, these segmentation video signal have determined it is image where respectively, thus each floor image shown in Fig. 4 corresponds to table
In, segmentation video signal region 201 is mapped with video camera setting place 202, and passes through elevator dock floor information 203
Again by them and the dock floor information association that is sent from elevator controlling portion 13.
Whether the elevator dock floor information 203 is for example being believed with the dock floor of elevator sent from elevator controlling portion 13
It ceases and is used in identical judgement.For example, being when " V1 " in segmentation video signal region 201 shows video camera setting place 202
" 1 stands layer by layer ", elevator dock floor information 203 are when showing 1 layer " 1 layer ", in the dock floor from elevator controlling portion 13
Information be notice elevator arrived or it is expected that reach 1 layer the case where when etc., referring to elevator dock floor information 203 " 1 layer ",
It is shown etc. using the image of corresponding " V1 ".
Back to Fig. 1, image reduces control unit 104 and uses the dock floor information sent from elevator controlling portion 13, each
Floor image corresponds to each floor image stored in table storage unit 103 and corresponds to the elevator dock floor information 203 in table and divide
The information in video signal region 201 according to the storage information of image resolution storage unit 109, will be written into according to described below
The segmentation video signal and the screen size of monitor 14 of memory 101 are cooperatively reduced, and are carried out as needed
Make the insertion process for cutting processing or upper and lower black-tape corresponding with the difference of aspect ratio, and storage is written as video signal is reduced
In device 101.
Image reduces/enlarges control unit 105 and uses the letter of the following floor by stop sent from elevator controlling portion 13
Breath corresponds to each floor image stored in table storage unit 103 in each floor image and corresponds to elevator dock floor information 203 in table
And the information in segmentation video signal region 201, to the segmentation video signal being written into memory 101, further progress reduces,
Amplify as needed, and made as needed it is corresponding with the difference of aspect ratio cut processing or up and down black-tape insert
Enter processing, and is written in memory 101 as video signal is reduced/enlarged.
It, will be into this in addition, the statement of " reducing/enlarging " refers to the meaning of " reduced, amplified as needed "
The additional explanation of row.
Video signal is reduced/enlarged by what the image reduced/enlarged that control unit 105 generates, is in order to which elevator is following
The image of the floor of stop is shown larger in monitor 14 and generate.Therefore, for dividing video signal, according to prison
The resolution ratio of visual organ 14 and the resolution ratio for dividing video signal reduce or amplify as needed, go forward side by side and exercise and indulge
The difference of horizontal ratio is corresponding to cut processing or the up and down insertion process of black-tape, and generation reduces/enlarges video signal.
Image processing department 106 corresponds to table using the dock floor information sent from elevator controlling portion 13, in each floor image
The information of the elevator dock floor information 203 and segmentation video signal region 201 that store in storage unit 103, stores to being written into
The diminution video signal for the floor that elevator is not stopped in the diminution video signal of device 101, carry out reduction brightness, removal color at
Point, mosaic processing or add the processing such as shade, and as reducing in processing video signal write-in memory 101.It will be to this
It is described later.
Image aligning section 107 is using the dock floor information sent from elevator controlling portion 13 and next by the floor of stop
Information, each floor image correspond to the elevator dock floor information 203 stored in table storage unit 103 and segmentation video signal area
The information in domain 201 reads from memory 101 and the floor of stop is next reduced/enlarged video signal, next by stop
Floor other than floor diminution video signal and reduce processing video signal, be configured to picture arrangement after display shadow
As in signal write-in memory 101.
That is, in image aligning section 107, to next by the image of the floor of stop, using reducing/enlarging video signal
Display is amplified, to floor in addition to this, diminution is carried out using diminution video signal or diminution processing video signal and shows.
About display example, will be illustrated in the action example below.
Image output portion 108 is written into memory 101 using the elevator operation information sent from elevator controlling portion 13, reading
In display video signal, and export to monitor 14.
Also, image resolution storage unit 109 stores the whole resolution of the image inputted from monitor recorder 11, segmentation
Shadow is reduced in number, the whole resolution of monitor 14, the micreikonic resolution ratio of contracting, the resolution ratio for reducing/enlarging image and generation
As and aspect ratio when reducing/enlarging image processing method.
In the following, being illustrated to action example.
The image as shown in Figure 2 by multiple surveillance cameras 12 is exported from monitor recorder 11 to show on a picture
Obtained image, using image display 10 image input cutting part 102 by the Image Segmentation be each image, and as point
It cuts in video signal write-in memory 101.
At this point, inputting cutting part 102, the shadow that the structure of the image inputted is exported from monitor recorder 11 about image
The whole resolution of picture and how being split is stored in image resolution storage unit 109, for example, if resolution ratio
Full HD 1920 points × 1080 points, segmentation number is 16, then use corresponding coordinate, be split according to shown in Fig. 2,
And as in segmentation video signal write-in memory 101.
It, can will be by this point, correspond to table according to each floor image stored in table storage unit 103 is corresponded in each floor image
Each segmentation video signal being written in memory 101 and the image association for being which floor.
Also, the shadow for the surveillance camera being arranged other than the stop of elevator is also recorded in monitor recorder 11 sometimes
Picture, thus in the elevator dock floor information 203 that each floor image of Fig. 4 corresponds to table, such as it is described as the part of "×"
It does not link with the dock floor information sent from elevator controlling portion 13.Even if as a result, monitor recorder 11 be common logger,
When recording/show image not related with elevator, if corresponding to the elevator dock floor information 203 of table to each floor image
"×" is described, then can not use such image.
Then, image reduces control unit 104, image reduces/enlarges control unit 105 and image processing department 106 is received from electricity
The dock floor information for the elevator that terraced control unit 13 is sent and next by the information of the floor of stop, and generate each shadow below
As signal.
Firstly, image reduces control unit 104 to the segmentation video signal of the Fig. 2 for being written into memory 101, using from elevator
The dock floor information and each floor image correspondence stored in table storage unit 103 is corresponded in each floor image that control unit 13 is sent
The segmentation image of dock floor is reduced and generates and reduce video signal, and is written in memory 101 by table.In addition, so-called stop
Floor refers to the floor that elevator can be stopped, although not including that for example there is floor, elevator do not stop or without door and
The floor etc. that cannot be stopped.
Here, the resolution ratio generated for reducing video signal is stored in image resolution storage unit 109.That is, contracting
The resolution ratio of small video signal refers to, in the resolution ratio for the image for use when picture arrangement by image aligning section 107, such as
The resolution ratio of monitor 14 is 320 points × 240 points, in the case where transversely arranged 4 diminutions image, a diminution video signal
As 80 points × 60 points.Also, in the case where arranging 5, become at 64 points × 48 points.Resolution about these monitors 14
Rate, the micreikonic number of arrangement contracting and the resolution ratio for dividing video signal for being written into memory 101, are pre-stored in
In image resolution storage unit 109, thus image, which reduces control unit 104, to determine minification referring to them.
Also, monitor recorder 11 is exported with full HD resolution ratio, aspect ratio 16:9, each segmentation image
Aspect ratio is also 16:9.
On the other hand, monitor 14 is in addition to aspect ratio is the monitor of 16:9, also just like above-mentioned 320 points × 240 points
The monitor of such 4:3.
Therefore, it reduces in control unit 104 in image, in order to cope with the difference of aspect ratio, is carried out together by the image of 16:9
Both ends delete become 4:3 aspect ratio cutting processing or 16:9 image up and down add black-tape become 4:3's
The additional processing of the black-tape up and down of aspect ratio.
Fig. 5, which shows the segmentation image for making at 480 points × 270 points of aspect ratio 16:9, becomes aspect ratio as the 360 of 4:3
The example of the cutting processing of point × 270 point.As shown in figure 5, both ends are deleted image data (Fig. 5 of × 270 point amounts at 60 points respectively
301,302), only show the image data (the 303 of Fig. 5) of × 270 point amounts at 360 points.
480 points × 270 points of the segmentation image of aspect ratio 16:9 is set to become aspect ratio as 4:3's alternatively, Fig. 6 is shown
The example of the additional processing of 480 points × 360 points of black-tape up and down.As shown in fig. 6, adding 480 points × 45 points of image respectively up and down
Data (311, the 312 of Fig. 6).
The processing method of difference as such reply aspect ratio, storage is in image resolution storage unit 109 in advance
It carries out cutting processing or carries out the additional processing of black-tape up and down, image reduces control unit 104 and handled referring to it.
Then, image reduces/enlarges control unit 105 for the segmentation video signal for the Fig. 2 being written into memory 101,
Next next dock floor information of the floor of stop and each building will be stored in using showing of sending from elevator controlling portion 13
Layer image corresponds to each floor image in table storage unit 103 and corresponds to table, to next by the segmentation video signal of the floor of stop
It is reduced/enlarged, generation reduces/enlarges in video signal write-in memory 101.
Also, it is same as the image diminution processing of control unit 104, as needed, stored according to image resolution is stored in
The processing method of aspect ratio in portion 109 carries out deleting the both ends of the image of 16:9 into the cutting for becoming 4:3 aspect ratio together
Processing or the additional processing of black-tape up and down for adding black-tape up and down and becoming 4:3 aspect ratio of the image in 16:9.
Here, the resolution ratio for reducing/enlarging video signal generated is stored in image resolution storage unit 109.That is,
The resolution ratio for reducing/enlarging video signal refers to, the resolution ratio of the image used when being arranged by image aligning section 107,
Such as the resolution ratio of monitor 14 is 320 points × 240 points, is laterally divided into 4 parts, is longitudinally divided into 4 parts, will reduce image and is arranged in L
Word shape, will reduce/enlarge image be shown as contracting micreikonic transverse direction 3, longitudinal 3 amounts image in the case where, should
The resolution ratio for reducing/enlarging image becomes at 240 points × 180 points.
Display example at this time is shown in FIG. 7.In Fig. 7, image " S1 ", " S2 ", " S4~S8 " are reduced respectively and in Fig. 2
Raw video " V1 ", " V2 ", " V4~V8 " it is corresponding, the image " L3 " of Fig. 7 is the magnified image of " V3 " in Fig. 2.Fig. 2's is each
Dividing image size is 480 points × 270 points, and the micreikonic size that contracts is transversely arranged 4, thus a micreikonic resolution of contracting
Rate becomes at 80 points × 60 points.Magnified image " L3 " becomes micreikonic 3 amounts that contract, thus becomes at 240 points × 180 points, by shadow
Diminution processing is carried out as reducing/enlarging control unit 105, cuts processing or the additional processing of black-tape up and down, so that from original point
Cutting at 480 points × 270 points of resolution ratio of image becomes at 240 points × 180 points.
In addition, in the case where the resolution ratio of monitor 14 is 800 points × 600 points and similarly arrange with Fig. 7,
Reducing image (" S1 ", " S2 " etc.) becomes at 200 points × 150 points, and magnified image (" L3 ") becomes at 600 points × 450 points.Therefore, right
In magnified image L3, need to zoom at 480 points × 270 points of resolution ratio greater than original segmentation image." amplification " is somebody's turn to do to refer to, though
" diminution " (such case accounts for a greater part of) can also so be become according to the size of the picture of monitor 14 and resolution ratio, but as described above
Sometimes the meaning for also becoming " amplification ", uses the statement of " reducing/enlarging " herein.
In this way, the resolution ratio of monitor 14 can be predetermined, the number of image arrangement is reduced and reduce/enlarge shadow
The resolution ratio of picture, and image resolution is stored in advance in together with the resolution ratio of segmentation video signal for being written into memory 101
In storage unit 109, image reduces/enlarges control unit 105 and is referred to them to determine magnifying power or minification.
Then, image processing department 106 is for being written into the diminution video signal of memory 101, using from elevator controlling portion
The dock floor information of 13 transmissions expects the estimated dock floor information stopped and corresponds to table storage unit 103 in each floor image
Each floor image of middle storage corresponds to table, and the diminution video signal for carrying out the floor for not stopping elevator reduces brightness, removal face
Color ingredient, mosaic processing add the processing such as shade, and as reducing in processing video signal write-in memory 101.
In the processing of above-mentioned reduction brightness, made and reducing the luminance signal for reducing video signal without exception its at
For dimmed image.
In the processing of above-mentioned removal color component, make it by the way that the carrier chrominance signal for reducing video signal is set as zero
As black-and-white image.
In above-mentioned mosaic working process, will reduce video signal according to such as 8 points × 8 units carry out it is average and
Become the image to fog relative to original image.
Above-mentioned plus Shadows Processing is that existing pattern is superimposed upon to the processing reduced on video signal, becomes and is difficult to
Confirm the image of raw video.
In image aligning section 107, receives the dock floor information of the elevator sent from elevator controlling portion 13, next will
Next dock floor information of the floor of stop and it is expected that stop estimated dock floor information, using in each floor image
The information of the elevator dock floor information 203 and segmentation video signal region 201 that are stored in corresponding table storage unit 103, and use
It is written into the diminution video signal of memory 101, reduce/enlarge video signal and reduces processing video signal, is intended to
In the arrangement for the image that monitor 14 is shown, and as in display video signal write-in memory 101.
Fig. 8, which is elevator, to be run along ascent direction and reaches the display example before " 3 layers ".Image " L3 " is according to Fig.4,
Each floor image correspond to each elevator dock floor information 203 in table, " 3 layers " elevator floor stops be arranged surveillance camera
Image, reducing image " S1 ", " S2 " and " S4~S8 " is elevator floor stops in " 1 layer ", " 2 layers " and " 4 layers~8 layers " respectively
The image of the surveillance camera of setting.Also, about image " S1 " and " S2 " is reduced, since the next dock floor of elevator is
" 3 layers " process video signal without arrival " 1 layer " and " 2 layers ", thus using the diminution after being processed by image processing department 106.
Also, in the dock floor information of the elevator sent from elevator controlling portion 13, for example, when do not stop with reduce shadow
In the case where as " S5 " and " S7 " corresponding " 5 layers " and " 7 layers ", also added using diminution for reducing image " S5 " and " S7 "
Work video signal.Diminution image in addition to this uses diminution video signal.In addition, in fig. 8 for reducing processing image letter
Number display, showed as the part of " S1 " with grey.In addition, the grey is shown with oblique line portion in the accompanying drawings.Also,
It is same in later attached drawing, for reducing the display of processing video signal, showed with grey (oblique line portion).
In addition, as another display example, also it is configured to as shown in figure 9, when elevator is operated along ascent direction,
When next arriving at " 3 layers ", it is merely displayed in the shadow of the surveillance camera of the elevator floor stops setting of the floor of " 4 layers " or more
Picture.
The example for not stopping " 5 layers ", " 7 layers " and " 10 layers " is shown in FIG. 9, image " S5 ", " S7 " and " S10 " uses
Processing video signal is reduced, diminution image in addition to this uses diminution video signal.
Alternatively, it is also possible to be configured to, in the case that the range of operation for setting elevator is " 1 layer "~" 15 layers ", along rising
When direction is operated and reaches " 9 layers ", it is shown to top layer (15 layers) always as shown in Figure 10.
Figure 10 shows example when will stop " 9 layers ", and the magnified image signal of " L9 " expression " 9 layers " is passing through
Diminution image i.e. " S8 " of the surveillance camera of the elevator floor stops setting of " 8 layers " crossed and it is expected that " 10 layers " do not stopped and
