The microcomputer functions as the image processing unit 103 by executing a program stored in the memory by the processor. The program can be written to the memory in advance, or it can be provided via a telecommunication line or recorded on a memory card such as a memory card. As shown in FIG. 1, the video processing unit 103 includes a first face detecting unit 111, a second face detecting unit 112, a person detecting unit 113, an extracting unit 114, and a synthesizing unit 115.

第1面部檢測部111經由第1受理部101而自攝像終端40接收攝像終端40所拍攝之即時影像(當前影像)。第1面部檢測部111於跟蹤功能為有效之情形時，對當前影像進行面部感測。第1面部檢測部111將當前影像及由面部感測而得之感測結果輸出至提取部114。於感測結果中，包含人面部之有無，且於人面部存在於當前影像之情形時包含其位置資訊(第1位置資訊)。第1位置資訊為例如表示面部之區域之資訊。第1面部檢測部111於跟蹤功能無效之情形時，不進行面部感測，而將當前影像輸出至提取部114。The first face detecting unit 111 receives the live image (current image) captured by the imaging terminal 40 from the imaging terminal 40 via the first receiving unit 101. When the tracking function is enabled, the first face detecting unit 111 performs face sensing on the current image. The first face detecting unit 111 outputs the current image and the sensing result obtained by the face sensing to the extracting unit 114. The sensing result includes the presence or absence of a human face, and includes the position information (first position information) when the human face exists in the current image. The first position information is, for example, information indicating an area of the face. When the tracking function is disabled, the first face detecting unit 111 outputs the current image to the extracting unit 114 without performing face sensing.

第2面部檢測部112自第1記憶部104讀出記憶於第1記憶部104中且自當前時點向前回溯特定時間之影像(例如較當前時點3秒前之影像)。即，過去影像係拍攝時刻與當前影像之拍攝時刻不同之影像。第2面部檢測部112於跟蹤功能有效之情形時，對自第1記憶部104讀出之影像(過去影像)進行面部感測。第2面部檢測部112將過去影像、及由面部感測而得之感測結果輸出至提取部114。於感測結果中，包含人面部之有無，且於過去影像中存在人面部之情形時包含其位置資訊(第2位置資訊)。第2位置資訊例如係表示面部之區域之資訊。第2面部檢測部112於跟蹤功能無效之情形時，不進行面部感測，而將過去影像輸出至提取部114。The second face detecting unit 112 reads out from the first storage unit 104 the image stored in the first storage unit 104 and backtracking from the current time point to a predetermined time (for example, an image 3 seconds before the current time point). That is, in the past, the image was taken at a different time from the current image capture time. When the tracking function is enabled, the second face detecting unit 112 performs face sensing on the image (past image) read from the first storage unit 104. The second face detecting unit 112 outputs the past image and the sensing result obtained by the face sensing to the extracting unit 114. In the sensing result, the presence or absence of a human face is included, and the position information (second position information) is included in the case where a human face exists in the past image. The second position information is, for example, information indicating an area of the face. When the tracking function is disabled, the second face detecting unit 112 outputs the past video to the extracting unit 114 without performing face sensing.

人檢測部113經由第2受理部102而自外部終端50接收外部終端50所拍攝之即時影像(輸入影像)。人檢測部113於跟蹤功能有效之情形時，對輸入影像進行人感測。人檢測部113將輸入影像、及由人感測而得之感測結果輸出至提取部114。於感測結果中包含人之有無、及人存在於輸入影像之情形時之該人之位置資訊(第3位置資訊)。第3位置資訊例如係表示人之區域之資訊。人檢測部113於跟蹤功能無效之情形時，不進行人感測，而將輸入影像輸出至提取部114。The human detecting unit 113 receives the live video (input video) captured by the external terminal 50 from the external terminal 50 via the second receiving unit 102. The human detecting unit 113 performs human sensing on the input image when the tracking function is valid. The human detecting unit 113 outputs the input image and the sensing result sensed by the person to the extracting unit 114. The sensing result includes the presence or absence of the person and the position information of the person (the third position information) when the person exists in the input image. The third location information is, for example, information indicating a region of a person. When the tracking function is disabled, the human detecting unit 113 outputs the input image to the extracting unit 114 without performing human sensing.

提取部114係以對影像實施修剪，裁切該影像之一部分之方式構成。The extracting unit 114 is configured to trim the image and cut one of the images.

提取部114於跟蹤功能無效之情形時，基於與當前影像、過去影像及輸入影像之各者對應之顯示規定資訊，對當前影像、過去影像及輸入影像進行成為顯示對象之區域之裁切，且視需要進行縮小。When the tracking function is disabled, the extraction unit 114 performs cropping of the region to be displayed on the current image, the past image, and the input image based on the display predetermined information corresponding to each of the current image, the past image, and the input image, and Zoom out as needed.

提取部114於跟蹤功能有效之情形時，基於與當前影像、過去影像及輸入影像之各者對應之位置資訊(第1～第3位置資訊之任一者)實施修剪，對於當前影像、過去影像及輸入影像，裁切成為顯示對象之區域。具體而言，提取部114以位置資訊所示之人或面部之區域為中心，基於對應之顯示規定資訊所包含之裁切尺寸而進行修剪。提取部114視需要以顯示規定資訊所包含之縮小率將修剪後之影像縮小。When the tracking function is enabled, the extraction unit 114 performs cropping based on the position information (any of the first to third position information) corresponding to each of the current image, the past image, and the input image, and the current image and the past image. And input the image, and cut into the area to be displayed. Specifically, the extraction unit 114 performs cropping based on the crop size included in the corresponding display specification information centering on the area of the person or face indicated by the position information. The extraction unit 114 reduces the cropped image by the reduction ratio included in the display predetermined information as needed.

合成部115以於顯示終端30顯示經過修剪且依需要縮小之各影像之方式，根據成為顯示對象之影像之合計張數及影像之種類中至少一者，且基於配置資訊而決定畫面分割及畫面佈局。具體而言，合成部115根據合計張數及影像之種類中至少一者求出畫面之分割數(除下述按鈕顯示畫面以外之分割數)，決定與分割數相應之畫面佈局。合成部115依照所求出之畫面佈局，將各影像合成(排列)，產生1個合成影像。例如，合成部115於使用合計張數之情形時，合計張數成為分割數。又，合成部115於使用種類之情形時，根據所拍攝之終端及拍攝時刻而判別成為顯示對象之影像之種類，特定出顯示對象之影像，根據所特定出之影像之種類數而求出分割數。The synthesizing unit 115 determines at least one of the total number of images to be displayed and the type of the video, and determines the screen division and the screen based on the arrangement information, so that the display terminal 30 displays the respective images that have been trimmed and reduced as needed. layout. Specifically, the composition unit 115 determines the number of divisions of the screen (the number of divisions other than the button display screen described below) based on at least one of the total number of sheets and the type of the image, and determines the screen layout corresponding to the number of divisions. The synthesizing unit 115 synthesizes (arranges) the respective images in accordance with the obtained screen layout to generate one synthesized video. For example, when the combining unit 115 uses the total number of sheets, the total number of sheets becomes the number of divisions. Further, when the type of use is used, the synthesizing unit 115 determines the type of the image to be displayed based on the photographed terminal and the photographing time, specifies the image to be displayed, and obtains the segmentation based on the number of types of the specified image. number.

合成部115經由通信部107及控制裝置20而將所產生之合成影像發送至與作為自呼叫部106發送之控制信號之輸出目標的顯示終端30相同之顯示終端30。合成部115於發送合成影像時，對合成影像進行編碼(encode)，發送經編碼之合成影像。再者，經編碼之合成影像係作為影像信號發送。The synthesizing unit 115 transmits the generated synthesized video to the display terminal 30 which is the same as the display terminal 30 which is the output destination of the control signal transmitted from the calling unit 106 via the communication unit 107 and the control device 20. The synthesizing unit 115 encodes the synthesized video when transmitting the synthesized video, and transmits the encoded synthesized video. Furthermore, the encoded synthetic image is transmitted as a video signal.

再者，提取部114亦可以基於位置資訊，裁切包含所感測到之人或面部之最小之區域之方式進行修剪。於該情形時，提取部114對修剪後之影像(裁切之影像)之尺寸與顯示修剪後之影像之畫面之尺寸進行比較。提取部114根據比較結果而進行修剪後之影像之縮小。提取部114於根據比較結果，修剪後之影像之尺寸與畫面之尺寸相同之情形時，不進行縮小，設為原本之尺寸(等倍)。Furthermore, the extracting unit 114 may perform cropping in such a manner that the smallest area including the sensed person or face is cut based on the position information. In this case, the extracting unit 114 compares the size of the trimmed image (the cropped image) with the size of the screen displaying the trimmed image. The extraction unit 114 performs the reduction of the image after the cropping based on the comparison result. When the size of the image after trimming is the same as the size of the screen based on the comparison result, the extraction unit 114 does not perform the reduction and sets the original size (equal magnification).

通信部107包含用以經由控制裝置20與顯示終端30進行通信之通信介面。於本實施形態中，通信部107以可於大廳對講機10與顯示終端30之間雙向傳送聲音信號及控制信號之方式，構成為可與顯示終端30之間雙向通信。通信部107係以將自影像處理部103輸出之合成影像發送至顯示終端30之方式構成。The communication unit 107 includes a communication interface for communicating with the display terminal 30 via the control device 20. In the present embodiment, the communication unit 107 is configured to be capable of bidirectional communication with the display terminal 30 so that the audio signal and the control signal can be transmitted bidirectionally between the hall intercom 10 and the display terminal 30. The communication unit 107 is configured to transmit the synthesized video output from the image processing unit 103 to the display terminal 30.

其次，對控制裝置20進行說明。如圖1所示，控制裝置20包含通信部21。通信部21係用以與大廳對講機10及顯示終端30進行通信之通信介面。通信部21當自大廳對講機10接收到控制信號或合成影像時，將所接收之控制信號或合成影像發送至顯示終端30。Next, the control device 20 will be described. As shown in FIG. 1, the control device 20 includes a communication unit 21.

Hereinafter, a case where the visitor performs a specific operation on the calling unit 106 of the hall walkie-talkie 10 will be described.

首先，當大廳對講機10之呼叫部106受理特定操作時，大廳對講機10使攝像終端40開始攝像動作。攝像終端40將所拍攝之影像輸出至大廳對講機10。First, when the calling unit 106 of the hall intercom 10 accepts a specific operation, the hall intercom 10 causes the imaging terminal 40 to start an imaging operation. The imaging terminal 40 outputs the captured image to the hall walkie-talkie 10.

大廳對講機10之第1受理部101將攝像終端40所拍攝之影像寫入第1記憶部104，且作為當前影像輸出至影像處理部103。The first receiving unit 101 of the hall intercom 10 writes the image captured by the imaging terminal 40 to the first storage unit 104, and outputs it as the current video to the video processing unit 103.

第1面部檢測部111於跟蹤功能有效之情形時，對當前影像進行面部感測。具體而言，第1面部檢測部111對攝像終端40所拍攝之每一影像圖框進行面部感測。第1面部檢測部111將當前影像、及由面部感測而得之感測結果輸出至提取部114。第1面部檢測部111於跟蹤功能無效之情形時，不進行面部感測，而將當前影像輸出至提取部114。The first face detecting unit 111 performs face sensing on the current image when the tracking function is enabled. Specifically, the first face detecting unit 111 performs face sensing on each of the image frames captured by the imaging terminal 40. The first face detecting unit 111 outputs the current image and the sensing result sensed by the face to the extracting unit 114. When the tracking function is disabled, the first face detecting unit 111 outputs the current image to the extracting unit 114 without performing face sensing.

第2面部檢測部112自第1記憶部104沿時間序列讀出自當前時點向前回溯特定時間之過去影像(例如較當前時點早3秒之影像)。第2面部檢測部112於跟蹤功能有效之情形時，對自第1記憶部104讀出之過去影像進行面部感測。具體而言，第2面部檢測部112對沿時間序列讀出之過去影像之每一影像圖框進行面部檢測。第2面部檢測部112將過去影像及由面部感測而得之感測結果輸出至提取部114。第2面部檢測部112於跟蹤功能無效之情形時，不進行面部感測，而將過去影像輸出至提取部114。The second face detecting unit 112 reads out from the first memory unit 104 in the time series the past image of the past time from the current time point (for example, an image 3 seconds earlier than the current time point). When the tracking function is enabled, the second face detecting unit 112 performs face sensing on the past image read from the first storage unit 104. Specifically, the second face detecting unit 112 performs face detection on each of the image frames of the past images read in time series. The second face detecting unit 112 outputs the past image and the sensing result obtained by the face sensing to the extracting unit 114. When the tracking function is disabled, the second face detecting unit 112 outputs the past video to the extracting unit 114 without performing face sensing.

人檢測部113經由第2受理部102而自外部終端50接收外部終端50所拍攝之即時之輸入影像。人檢測部113於跟蹤功能有效之情形時，對輸入影像進行人感測。人檢測部113將輸入影像、及由人感測而得之感測結果輸出至提取部114。人檢測部113於跟蹤功能無效之情形時，不進行人感測，而將輸入影像輸出至提取部114。The human detecting unit 113 receives an instant input image captured by the external terminal 50 from the external terminal 50 via the second receiving unit 102. The human detecting unit 113 performs human sensing on the input image when the tracking function is valid. The human detecting unit 113 outputs the input image and the sensing result sensed by the person to the extracting unit 114. When the tracking function is disabled, the human detecting unit 113 outputs the input image to the extracting unit 114 without performing human sensing.

提取部114於跟蹤功能無效之情形時，基於與當前影像、過去影像及輸入影像各者對應之顯示規定資訊，對當前影像、過去影像及輸入影像裁切成為顯示對象之區域。具體而言，於針對當前影像之顯示規定資訊中，包含規定裁切位置之第1座標(a1，b1)、及橫向之長度L1、縱向之長度H1。於針對過去影像之顯示規定資訊中，包含規定裁切位置之第2座標(c1，d1)、及橫向之長度L2、縱向之長度H2。於針對輸入影像之顯示規定資訊中，包含規定裁切位置之第3座標(e1，f1)、及橫向之長度L3、縱向之長度H3。如圖3A所示，提取部114對於當前影像G20，裁切以第1座標(a1，b1)為起點、且以橫向之長度L1及縱向之長度H1所規定之區域作為顯示範圍G25。如圖3B所示，提取部114對於過去影像G21，裁切以第2座標(c1，d1)為起點、且以橫向之長度L2及縱向之長度H2所規定之區域作為顯示範圍G26。如圖3C所示，提取部114對於輸入影像G22，裁切以第3座標(e1，f1)為起點、且以橫向之長度L3及縱向之長度H3所規定之區域作為顯示範圍G27。提取部114視需要依照對應之顯示規定資訊之縮小率，對經裁切之顯示範圍G25～G27(經修剪之當前影像、過去影像及輸入影像)進行縮小。再者，於本實施形態中，不進行縮小而設為等倍。When the tracking function is disabled, the extraction unit 114 crops the current image, the past image, and the input image into an area to be displayed based on the display predetermined information corresponding to each of the current image, the past image, and the input image. Specifically, the display specification information for the current image includes the first coordinate (a1, b1) defining the cutting position, the length L1 in the lateral direction, and the length H1 in the vertical direction. The display specification information for the past image includes the second coordinate (c1, d1) specifying the cutting position, the length L2 in the lateral direction, and the length H2 in the vertical direction. The display information for the input image includes the third coordinate (e1, f1) of the specified cutting position, the horizontal length L3, and the longitudinal length H3. As shown in FIG. 3A, the extraction unit 114 cuts a region defined by the first coordinate (a1, b1) from the current image G20 and defined by the horizontal length L1 and the longitudinal length H1 as the display range G25. As shown in FIG. 3B, the extraction unit 114 cuts a region defined by the second coordinate (c1, d1) as a starting point and a length L2 in the lateral direction and a length H2 in the vertical direction as the display range G26. As shown in FIG. 3C, the extraction unit 114 cuts the region defined by the third coordinate (e1, f1) as the starting point and the length L3 in the lateral direction and the length H3 in the vertical direction as the display range G27. The extracting unit 114 reduces the cropped display ranges G25 to G27 (the cropped current image, the past image, and the input image) as needed in accordance with the reduction ratio of the corresponding display predetermined information. Furthermore, in the present embodiment, the magnification is set to be equal to no reduction.

提取部114於跟蹤功能有效之情形時，基於與當前影像、過去影像及輸入影像各者對應之位置資訊(第1～第3位置資訊之任一者)實施修剪，對當前影像、過去影像及輸入影像裁切成為顯示對象之區域。具體而言，如圖4A所示，提取部114對於當前影像G20，基於第1位置資訊而求出當前影像所包含之面部之區域G30，裁切以區域G30為中心、且以橫向之長度L1及縱向之長度H1所規定之區域作為顯示範圍G35。如圖4B所示，提取部114對於過去影像G21，基於第2位置資訊而求出過去影像所包含之面部之區域G31，裁切以區域G31為中心、且以橫向之長度L2及縱向之長度H2所規定之區域作為顯示範圍G36。如圖4C所示，提取部114對於輸入影像G22，基於第3位置資訊而求出輸入影像所包含之人之區域G32，裁切以區域G32為中心、且以橫向之長度L3及縱向之長度H3所規定之區域作為顯示範圍G37。When the tracking function is enabled, the extraction unit 114 performs cropping based on the position information (any of the first to third position information) corresponding to each of the current image, the past image, and the input image, and the current image and the past image and The input image is cropped to become the area of the display object. Specifically, as shown in FIG. 4A, the extraction unit 114 obtains the region G30 of the face included in the current image based on the first position information for the current image G20, and cuts the length L1 centered on the region G30. The area defined by the length H1 of the longitudinal direction is defined as the display range G35. As shown in FIG. 4B, the extraction unit 114 obtains the region G31 of the face included in the past image based on the second position information with respect to the past image G21, and cuts the length L2 and the length of the vertical direction centering on the region G31. The area specified by H2 is used as the display range G36. As shown in FIG. 4C, the extraction unit 114 obtains the region G32 of the person included in the input image based on the third position information on the input image G22, and cuts the length L3 and the length of the vertical direction centering on the region G32. The area specified by H3 is used as the display range G37.

提取部114於跟蹤功能有效之情形時，若根據第1面部檢測部111之感測結果，當前影像中之面部之位置自區域G30移動至區域G40，則裁切以移動後之面部之區域G40為中心、且以橫向之長度L1及縱向之長度H1所規定之區域作為顯示範圍G35(參照圖4D)。提取部114於跟蹤功能有效之情形時，若根據第2面部檢測部112之感測結果，過去影像中之面部之位置自區域G31移動至區域G41，則裁切以移動後之面部之區域G41為中心、且以橫向之長度L2及縱向之長度H2所規定之區域作為顯示範圍G36(參照圖4E)。提取部114於跟蹤功能有效之情形時，若根據人檢測部113之感測結果，輸入影像中之人之位置自區域G32移動至區域G42，則裁切以移動後之人之區域G42為中心、且以橫向之長度L3及縱向之長度H3所規定之區域作為顯示範圍G37(參照圖4F)。When the tracking function is enabled, the extraction unit 114 changes the position of the face in the current image from the region G30 to the region G40 according to the sensing result of the first face detecting unit 111, and then crops the region G40 of the moved face. A region defined by the length L1 in the lateral direction and the length H1 in the longitudinal direction is defined as the display range G35 (see FIG. 4D). When the tracking function is enabled, the extraction unit 114 shifts the position of the face in the past image from the region G31 to the region G41 based on the sensing result of the second face detecting unit 112, and cuts the region G41 of the face after the movement. A region defined by the length L2 in the lateral direction and the length H2 in the longitudinal direction is the display range G36 (see FIG. 4E). When the tracking function is enabled, the extraction unit 114 moves the position of the person in the input image from the area G32 to the area G42 according to the sensing result of the human detecting unit 113, and then cuts the area G42 of the moved person as the center. The area defined by the lateral length L3 and the longitudinal length H3 is defined as the display range G37 (see FIG. 4F).

提取部114視需要依照對應之顯示規定資訊之縮小率，對所裁切之顯示範圍G35～G37(經修剪之當前影像、過去影像及輸入影像)進行縮小。再者，於本實施形態中，不進行縮小而設為等倍。The extraction unit 114 reduces the cropped display ranges G35 to G37 (the cropped current image, the past image, and the input image) in accordance with the reduction ratio of the corresponding display predetermined information. Furthermore, in the present embodiment, the magnification is set to be equal to no reduction.

合成部115根據合計張數及影像之種類中至少一者而求出畫面之分割數，從而決定與分割數相應之畫面佈局。此處，除按鈕顯示畫面以外之分割數為3，求出顯示畫面G10作為與其對應之畫面佈局。The synthesizing unit 115 obtains the number of divisions of the screen based on at least one of the total number of sheets and the type of the image, and determines the screen layout corresponding to the number of divisions. Here, the number of divisions other than the button display screen is three, and the display screen G10 is obtained as the screen layout corresponding thereto.

合成部115基於配置資訊而將經修剪且視需要縮小之各影像合成(排列)，產生1個合成影像。具體而言，合成部115以將各影像顯示於顯示畫面G10中所對應之畫面(主畫面G11、第1副畫面G12及第2副畫面G13之任一畫面)之方式，由各影像產生1個合成影像。例如，於跟蹤功能無效之情形時，合成部115由視需要縮小之顯示範圍G25～G27產生1個合成影像(參照圖3D)。再者，於本實施形態中，如上所述，顯示範圍G25～G27未進行縮小。合成部115將產生之合成影像發送至顯示終端30。The synthesizing unit 115 synthesizes (arranges) the respective images that have been cropped and reduced as needed based on the arrangement information, thereby generating one synthesized image. Specifically, the synthesizing unit 115 generates 1 for each video so that each video is displayed on the screen corresponding to the display screen G10 (the main screen G11, the first sub-screen G12, and the second sub-screen G13). A composite image. For example, when the tracking function is invalid, the synthesizing unit 115 generates one synthesized image from the display ranges G25 to G27 that are reduced as needed (see FIG. 3D). Furthermore, in the present embodiment, as described above, the display ranges G25 to G27 are not reduced. The synthesizing unit 115 transmits the generated synthesized image to the display terminal 30.

顯示終端30藉由於顯示部33顯示合成影像，而可將1個畫面分割，顯示3種影像。The display terminal 30 can divide one screen and display three types of images by displaying the synthesized image on the display unit 33.

(3)實施形態1之變化例 於上述實施形態中，於大廳對講機10中跟蹤功能無效之情形時，顯示部33亦可將指示變更裁切位置之滾動按鈕與合成影像共同顯示。具體而言，於分別顯示各影像(當前影像、過去影像及輸入影像)之畫面中，顯示滾動按鈕(參照圖5A)。於主畫面G11中，分別顯示將裁切位置向左變更之第1滾動按鈕SC1、及向右變更之第2滾動按鈕SC2。於第1副畫面G12中，分別顯示將裁切位置向上變更之第3滾動按鈕SC3、及向左變更之第4滾動按鈕SC4、將裁切位置向右變更之第5滾動按鈕SC5、及向下變更之第6滾動按鈕SC6。於第2副畫面G13中，分別顯示將裁切位置向上變更之第7滾動按鈕SC7、及左向變更之第8滾動按鈕SC8、將裁切位置向右變更之第9滾動按鈕SC9、及向下變更之第10滾動按鈕SC10。(3) Modification of the first embodiment In the above embodiment, when the tracking function in the hall intercom 10 is invalid, the display unit 33 may display the scroll button indicating the change of the cutting position together with the composite image. Specifically, a scroll button is displayed on a screen in which each image (current image, past image, and input image) is displayed (see FIG. 5A). On the main screen G11, the first scroll button SC1 that changes the cutting position to the left and the second scroll button SC2 that changes to the right are respectively displayed. In the first sub-screen G12, a third scroll button SC3 that changes the cutting position upward, a fourth scroll button SC4 that changes to the left, a fifth scroll button SC5 that changes the cutting position to the right, and a direction are respectively displayed. The sixth scroll button SC6 is changed. In the second sub-screen G13, the seventh scroll button SC7 that changes the cutting position upward, the eighth scroll button SC8 that changes leftward, the nineth scroll button SC9 that changes the cutting position to the right, and the direction are respectively displayed. The 10th scroll button SC10 is changed.

例如，當第5滾動按鈕SC5被按下時，提取部114根據按下之時間或按下之次數，將成為裁切顯示範圍之基準之第2座標(c1，d1)變更為座標(c2，d1)。此處，c2為大於c1之值。提取部114裁切以座標(c2，d1)為起點、且以橫向之長度L2及縱向之長度H2所規定之區域作為顯示範圍G26(參照圖5B)。For example, when the fifth scroll button SC5 is pressed, the extraction unit 114 changes the second coordinate (c1, d1) which is the reference of the cropping display range to the coordinate (c2, based on the time of pressing or the number of times of pressing). D1). Here, c2 is a value larger than c1. The extraction unit 114 cuts a region defined by the coordinates (c2, d1) as the starting point and the length L2 in the lateral direction and the length H2 in the vertical direction as the display range G26 (see FIG. 5B).

又，於大廳對講機10中跟蹤功能無效之情形時，顯示部33亦可將對攝像終端40及外部終端50之至少1個終端指示變更拍攝範圍及拍攝位置之至少1者之變更指示按鈕與合成影像共同顯示。例如，當對攝像終端40指示拍攝位置之變更時，影像處理部103變更攝像終端40之鏡頭之朝向。藉此，可變更攝像終端40之拍攝範圍。影像處理部103自變更了拍攝範圍後之攝像終端40所拍攝之影像裁切顯示範圍G25或顯示範圍G26。又，當對外部終端50指示拍攝位置之變更時，影像處理部103變更外部終端50之鏡頭之朝向。藉此，可變更外部終端50之拍攝範圍。影像處理部103自變更了拍攝範圍後之外部終端50所拍攝之影像裁切顯示範圍G27。Further, when the tracking function is disabled in the hall intercom 10, the display unit 33 may instruct at least one of the imaging terminal 40 and the external terminal 50 to change the indication button and the combination of at least one of the imaging range and the imaging position. The images are displayed together. For example, when the imaging terminal 40 is instructed to change the imaging position, the video processing unit 103 changes the orientation of the lens of the imaging terminal 40. Thereby, the imaging range of the imaging terminal 40 can be changed. The image processing unit 103 cuts the display range G25 or the display range G26 from the image captured by the imaging terminal 40 after the imaging range is changed. Further, when the external terminal 50 is instructed to change the imaging position, the video processing unit 103 changes the orientation of the lens of the external terminal 50. Thereby, the shooting range of the external terminal 50 can be changed. The image processing unit 103 cuts the display range G27 from the image captured by the external terminal 50 after changing the imaging range.

又，跟蹤功能係設為於攝像終端40及外部終端50所拍攝之各影像之範圍內跟蹤被攝體之功能。跟蹤功能亦可以如下方式控制該終端：於被攝體成為影像之範圍外之情形時，對於拍攝該影像之攝像終端40或外部終端50，變更拍攝範圍及拍攝位置之至少1者。或，亦可設置對該終端以變更拍攝範圍及拍攝位置之至少1者之方式進行指示的按鈕。Further, the tracking function is a function of tracking the subject within the range of each image captured by the imaging terminal 40 and the external terminal 50. The tracking function may also control the terminal in such a manner that when the subject is out of the range of the image, at least one of the imaging range and the imaging position is changed for the imaging terminal 40 or the external terminal 50 that has captured the image.

第2面部檢測部302自第1記憶部36A沿時間序列讀出自當前時點向前回溯特定時間之過去影像(例如較當前時點3秒前之影像)。第2面部檢測部302於跟蹤功能有效之情形時，對自第1記憶部36A讀出之過去影像進行面部感測。第2面部檢測部302將過去影像及由面部感測而得之感測結果輸出至提取部303。第2面部檢測部302於跟蹤功能無效之情形時，不進行面部感測，而將過去影像輸出至提取部303。The second face detecting unit 302 reads out from the first memory unit 36A the past image from the current time point back to the specific time (for example, an image 3 seconds before the current time point). When the tracking function is enabled, the second face detecting unit 302 performs face sensing on the past image read from the first storage unit 36A. The second face detecting unit 302 outputs the past image and the sensing result obtained by the face sensing to the extracting unit 303. When the tracking function is disabled, the second face detecting unit 302 outputs the past video to the extracting unit 303 without performing face sensing.

提取部303於跟蹤功能無效之情形時，基於與當前影像及過去影像之各者對應之顯示規定資訊，對當前影像及過去影像裁切成為顯示對象之區域。具體而言，於關於當前影像之顯示規定資訊中，與實施形態1同樣地包含規定裁切位置之第1座標(a1，b1)、及橫向之長度L1、縱向之長度H1。於關於過去影像之顯示規定資訊中，包含規定裁切位置之第2座標(x1，y1)、及橫向之長度L4、縱向之長度H4。如圖8A所示，提取部303對於當前影像G200，裁切以第1座標(a1，b1)為起點且以橫向之長度L1及縱向之長度H1所規定之區域作為顯示範圍G250。如圖8B所示，提取部303對於過去影像G201，裁切以第2座標(x1，y1)為起點且以橫向之長度L4及縱向之長度H4所規定之區域作為顯示範圍G260。提取部303視需要對於所裁切之顯示範圍G250、G260(經修剪之當前影像、過去影像)，依照對應之顯示規定資訊之縮小率進行縮小。When the tracking function is invalid, the extraction unit 303 cuts the current image and the past image into the display target region based on the display predetermined information corresponding to each of the current image and the past image. Specifically, in the display specification information on the current image, the first coordinate (a1, b1) defining the cutting position, the length L1 in the lateral direction, and the length H1 in the vertical direction are included in the same manner as in the first embodiment. The information on the display of the past image includes the second coordinate (x1, y1) defining the cutting position, the length L4 in the lateral direction, and the length H4 in the vertical direction. As shown in FIG. 8A, the extraction unit 303 cuts a region defined by the first coordinate (a1, b1) as the starting point and the length L1 in the lateral direction and the length H1 in the vertical direction as the display range G250. As shown in FIG. 8B, the extraction unit 303 cuts a region defined by the second coordinate (x1, y1) from the past coordinate G201 with the horizontal length L4 and the vertical length H4 as the display range G260. The extraction unit 303 reduces the display range G250 and G260 (the current image that has been cropped and the past image) as needed according to the reduction ratio of the corresponding display predetermined information.

提取部303於跟蹤功能有效之情形時，基於與當前影像及過去影像之各者對應之位置資訊(第1～第2位置資訊之任一者)實施修剪，對於當前影像及過去影像裁切成為顯示對象之區域。具體而言，提取部303對於當前影像，基於第1位置資訊而求出當前影像所包含之面部之區域(第1區域)，裁切以第1區域為中心且以橫向之長度L1及縱向之長度H1所規定之區域作為第1顯示範圍。提取部303對於過去影像，基於第2位置資訊而求出過去影像所包含之面部之區域(第2區域)，裁切以第2區域為中心且以橫向之長度L4及縱向之長度H4所規定之區域作為第2顯示範圍。When the tracking function is enabled, the extraction unit 303 performs cropping based on the position information (any of the first to second position information) corresponding to each of the current image and the past image, and crops the current image and the past image. Displays the area of the object. Specifically, the extraction unit 303 obtains a region (first region) of the face included in the current video based on the first position information for the current image, and cuts the length L1 and the vertical direction centering on the first region. The area defined by the length H1 serves as the first display range. The extraction unit 303 obtains a region (second region) of the face included in the past image based on the second position information for the past video, and the cutting is defined by the length L4 and the length H4 of the vertical direction centering on the second region. The area is the second display range.

提取部303於跟蹤功能有效之情形時，若以攝像終端40拍攝影像中，當前影像所包含之面部之位置移動，則根據面部感測之結果，基於移動後之第1位置資訊而再次求出當前影像所包含之面部之區域。提取部303裁切以再次求出之面部之區域為中心且以橫向之長度L1及縱向之長度H1所規定之區域作為第1顯示範圍。提取部303於跟蹤功能有效之情形時，若自第1記憶部36A所接收之過去影像所包含之面部之位置移動，則根據面部感測之結果，基於移動後之第2位置資訊而再次求出過去影像所包含之面部之區域。提取部303裁切以再次求出之面部之區域為中心且以橫向之長度L4及縱向之長度H4所規定之區域作為第2顯示範圍。When the tracking function is enabled, the extraction unit 303 re-determines the position of the face included in the current image when the image is captured by the imaging terminal 40, based on the result of the face sensing, based on the first position information after the movement. The area of the face contained in the current image. The extraction unit 303 cuts a region defined by the region of the face that is obtained again and has a length L1 in the lateral direction and a length H1 in the longitudinal direction as the first display range. When the tracking function is enabled, the extraction unit 303 moves again based on the result of the face sensing based on the second position information after the movement, if the position of the face included in the past video received by the first storage unit 36A is moved. The area of the face contained in the past image. The extraction unit 303 cuts a region defined by the region of the face that is obtained again and has a length L4 and a length H4 in the vertical direction as the second display range.

提取部303視需要對所裁切之第1及第2顯示範圍(經修剪之當前影像及過去影像)，依照對應之顯示規定資訊之縮小率進行縮小。The extraction unit 303 reduces the first and second display ranges (the cropped current image and the past image) that are cropped as needed in accordance with the reduction ratio of the corresponding display predetermined information.

合成部304根據合計張數及影像之種類中至少一者而求出畫面之分割數，從而求出與分割數相應之畫面構成。此處，除按鈕顯示畫面以外之分割數為2，求出顯示畫面G100作為與其對應之畫面佈局。The synthesizing unit 304 obtains the number of divisions of the screen based on at least one of the total number of sheets and the type of the image, and obtains a screen configuration corresponding to the number of divisions. Here, the number of divisions other than the button display screen is 2, and the display screen G100 is obtained as the screen layout corresponding thereto.

合成部304基於配置資訊而對經修剪且視需要縮小之各影像進行合成(排列)，產生1個合成影像。具體而言，合成部304以將各影像顯示於顯示畫面G100中所對應之畫面(主畫面G101及副畫面G102之任一畫面)之方式，由各影像產生1個合成影像。例如於跟蹤功能無效之情形時，合成部304由依照對應之顯示規定資訊之縮小率而縮小之顯示範圍G250、G260，產生1個合成影像(參照圖8C)。合成部304將所產生之合成影像輸出至顯示部33A。The synthesizing unit 304 synthesizes (arranges) each of the trimmed and reduced images as needed based on the arrangement information, and generates one synthesized video. Specifically, the synthesizing unit 304 generates one synthesized video from each video so that each video is displayed on a screen (either one of the main screen G101 and the sub-screen G102) corresponding to the display screen G100. For example, when the tracking function is invalid, the synthesizing unit 304 generates one synthesized image by the display ranges G250 and G260 which are reduced in accordance with the reduction ratio of the corresponding display predetermined information (see FIG. 8C). The synthesizing unit 304 outputs the generated synthesized image to the display unit 33A.

顯示終端30A藉由將合成影像顯示於顯示部33A，而可分割1個畫面來顯示2種影像。The display terminal 30A can display two types of images by dividing one screen by displaying the synthesized image on the display unit 33A.

其次，對實施形態2之變化例進行說明。Next, a modification of the second embodiment will be described.

於上述實施形態中，於影像處理部300中跟蹤功能無效之情形時，顯示部33A亦可與實施形態1之變化例同樣地將指示變更裁切位置之滾動按鈕與合成影像共同顯示。In the above-described embodiment, when the tracking function is disabled in the image processing unit 300, the display unit 33A can display the scroll button instructing the change of the cutting position together with the synthesized image in the same manner as the modification of the first embodiment.

又，於影像處理部300中跟蹤功能無效之情形時，顯示部33A亦可與實施形態1之變化例同樣地，將對於攝像終端40指示變更拍攝範圍及拍攝位置之至少1者之變更指示按鈕與合成影像共同顯示。When the tracking function is disabled in the video processing unit 300, the display unit 33A can instruct the imaging terminal 40 to change the instruction button for changing at least one of the imaging range and the imaging position, similarly to the modification of the first embodiment. Displayed together with the composite image.

如以上說明，可謂影像處理部300根據使用者之指示，對於當前影像及過去影像之至少1個影像，調整拍攝範圍、拍攝位置及顯示範圍中至少1者。As described above, the image processing unit 300 adjusts at least one of the imaging range, the imaging position, and the display range for at least one of the current image and the past image based on the user's instruction.

於上述實施形態中，構成為於跟蹤功能無效之情形時，將提取部303所裁切之各影像以對應之縮小率縮小，但並不限定於該構成。於跟蹤功能無效之情形時，亦可將提取部303所裁切之各影像放大。例如，將所裁切之範圍設為較對應之畫面(主畫面G101及副畫面G102)之尺寸更小之範圍。提取部303於所裁切之影像之尺寸與對應之畫面之尺寸相比可放大之情形時，將所裁切之影像放大。或，提取部303亦可具有將影像縮小之功能與放大之功能之兩者。In the above-described embodiment, when the tracking function is invalid, the respective images cut by the extraction unit 303 are reduced by the corresponding reduction ratio, but the configuration is not limited thereto. When the tracking function is invalid, each image cut by the extraction unit 303 may be enlarged. For example, the cropped range is set to be smaller than the size of the corresponding screen (main screen G101 and sub-screen G102). The extracting unit 303 enlarges the cropped image when the size of the cropped image is larger than the size of the corresponding screen. Alternatively, the extraction unit 303 may have both a function of reducing the image and a function of amplifying the image.

於上述實施形態中，構成為攝像終端40包含於玄關子機60，但並不限定於該構成。亦可為攝像終端40不包含於玄關子機60之構成。In the above embodiment, the imaging terminal 40 is included in the entrance sub-machine 60, but the configuration is not limited thereto. It is also possible that the imaging terminal 40 is not included in the configuration of the entrance sub-machine 60.

又，本實施形態之對講機系統1A亦可構成為進而包含外部終端50。此時，當顯示終端30A自外部終端50直接接收到輸入影像，或經由玄關子機60而自外部終端50接收到輸入影像時，影像處理部300與實施形態1之影像處理部103同樣地進行動作，使顯示部33A顯示3種影像。Further, the walkie-talkie system 1A of the present embodiment may be configured to further include an external terminal 50. At this time, when the display terminal 30A directly receives the input image from the external terminal 50 or receives the input image from the external terminal 50 via the entrance sub-machine 60, the image processing unit 300 performs the same process as the video processing unit 103 of the first embodiment. The operation causes the display unit 33A to display three types of images.

或，於本實施形態之對講機系統1A為包含外部終端50之構成之情形時，亦可並非為上述顯示3種影像之構成，而為顯示3種中之2種影像之構成。例如，亦可構成為於主畫面G101中顯示當前影像，於副畫面G102中顯示過去影像及輸入影像之一種影像。此時，亦可構成為於副畫面G102中，藉由按下畫面切換按鈕而自一種影像切換為另一種影像。Alternatively, when the walkie-talkie system 1A of the present embodiment is configured to include the external terminal 50, the configuration may be such that three types of images are displayed instead of the three types of images. For example, the current image may be displayed on the main screen G101, and one image of the past image and the input image may be displayed on the sub-screen G102. In this case, the sub-screen G102 may be configured to switch from one type of image to another by pressing the screen switching button.

於上述實施形態中，設為主畫面G101與副畫面G102橫向排列之畫面佈局(參照圖7A、7B)，但並不限定於該畫面佈局。亦可為主畫面G101與副畫面G102縱向排列之畫面佈局(參照圖9A)。In the above embodiment, the screen layout in which the main screen G101 and the sub screen G102 are arranged side by side (see FIGS. 7A and 7B) is not limited to the screen layout. A screen layout in which the main screen G101 and the sub-screen G102 are vertically arranged may be referred to (see FIG. 9A).

於上述實施形態中，構成為顯示終端30A包含影像處理部300，但並不限定於該構成。亦可為玄關子機60包含影像處理部300之構成。In the above embodiment, the display terminal 30A includes the video processing unit 300, but the configuration is not limited thereto. The configuration of the image processing unit 300 may be included in the entrance sub-machine 60.

又，影像處理部300並非必須由顯示終端30A及玄關子機60中之任1個終端(裝置)構成。影像處理部300之功能亦可分散於複數個終端(裝置)。例如，影像處理部300之功能亦可分散設置於顯示終端30A及玄關子機60。Further, the video processing unit 300 does not need to be constituted by any one of the display terminal 30A and the entrance sub-machine 60 (device). The functions of the image processing unit 300 may be distributed over a plurality of terminals (devices). For example, the functions of the image processing unit 300 may be distributed to the display terminal 30A and the entrance sub-machine 60.

於上述實施形態中，構成為對於各影像(當前影像及過去影像)具有跟蹤功能，但並不限定於該構成。只要對當前影像及過去影像中至少1種影像具有跟蹤功能即可。In the above embodiment, the tracking function is provided for each image (current image and past image), but the configuration is not limited thereto. As long as at least one of the current image and the past image has a tracking function.

如以上說明，於本實施形態及變化例之對講機系統中，對當前影像及過去影像實施修剪。因此，即便於將該等影像一次顯示於顯示畫面G100之情形時，與未實施修剪之情形時相比，各影像更加容易觀看。As described above, in the walkie-talkie system of the embodiment and the modification, the current image and the past image are trimmed. Therefore, even when the images are displayed on the display screen G100 at a time, each image is easier to view than when the cropping is not performed.

(其他變化例) 以下，列舉變化例。再者，以下說明之變化例可與上述各實施形態適當組合應用。(Other Variations) Hereinafter, a variation will be described. Further, the modifications described below can be applied in appropriate combination with the above embodiments.

於上述實施形態1中，構成為對講機系統1將當前影像、過去影像及輸入影像之3種影像全部顯示於顯示終端30，但並不限定於該構成。亦可為對講機系統1將當前影像、過去影像及輸入影像中之2種影像顯示於顯示終端30的構成。該情形時之畫面佈局可藉由應用實施形態2中所述之畫面佈局實現。In the first embodiment, the walkie-talkie system 1 displays all of the three types of images of the current image, the past image, and the input image on the display terminal 30. However, the present invention is not limited to this configuration. The walkie-talkie system 1 may also display two types of current images, past images, and input images on the display terminal 30. The screen layout in this case can be realized by applying the screen layout described in Embodiment 2.

又，於實施形態1中，構成為分別顯示3種影像，於實施形態2中，構成為分別顯示2種影像，但並不限定於該構成。亦可顯示4種以上之影像。例如，於實施形態1中，可應用於對講機系統1包含2個以上之外部終端50之情形。Further, in the first embodiment, three kinds of images are displayed, and in the second embodiment, two types of images are separately displayed, but the configuration is not limited thereto. More than 4 types of images can also be displayed. For example, in the first embodiment, it is applicable to the case where the walkie-talkie system 1 includes two or more external terminals 50.

將該情形時之畫面佈局之一例表示於圖9B、9C。圖9B為顯示6種影像之情形時之畫面佈局，對於對講機系統1包含4個外部終端50之情形有效。畫面G300包含主畫面G301、5個副畫面G302～G306。於主畫面G301中，顯示當前影像。於副畫面G302中顯示過去圖像，於副畫面G303～G306中，分別顯示對應之外部終端50各自所拍攝之輸入影像。圖9C為顯示5種影像之情形時之畫面佈局，對於對講機系統1包含3個外部終端50之情形時有效。畫面G400包含主畫面G401、4個副畫面G402～G405。於主畫面G401中，顯示當前影像。於副畫面G402中，顯示過去圖像，於副畫面G403～G405中，分別顯示對應之外部終端50各自所拍攝之輸入影像。再者，於圖9B、9C中，省略按鈕顯示畫面。An example of the screen layout in this case is shown in FIGS. 9B and 9C. Fig. 9B is a screen layout in the case of displaying six kinds of images, and is effective for the case where the interphone system 1 includes four external terminals 50. The screen G300 includes a main screen G301 and five sub-screens G302 to G306. In the main screen G301, the current image is displayed. The past image is displayed on the sub-screen G302, and the input images captured by the corresponding external terminals 50 are displayed on the sub-screens G303 to G306. Fig. 9C is a screen layout in the case of displaying five kinds of images, and is effective when the walkie-talkie system 1 includes three external terminals 50. The screen G400 includes a main screen G401 and four sub-screens G402 to G405. In the main screen G401, the current image is displayed. In the sub-screen G402, the past image is displayed, and the input images captured by the corresponding external terminals 50 are respectively displayed on the sub-screens G403 to G405. In addition, in FIGS. 9B and 9C, the button display screen is omitted.
