　また、同図に示すように、撮像地の設定画面では、画面中央にポインタＰが表示される。ユーザは、ポインタＰで撮像地とする場所を指定する。 Further, as shown in the figure, on the setting screen of the imaging location, the pointer P is displayed at the center of the screen. The user uses the pointer P to designate a place to be an imaging location.
　撮像地の指定は、次のように行われる。すなわち、必要に応じて地図を拡大、縮小又は移動させ、撮像地とする場所をポインタＰの位置（画面中央）に合わせる。その後、ＯＫボタン８を押す。これにより、撮像地が設定される。撮像地設定処理部５０ａは、ＯＫボタン８が押された時にポインタＰが位置している場所を撮像地設定として設定する。 The designation of the imaging location is performed as follows. That is, the map is enlarged, reduced or moved as needed, and the place to be the imaging location is aligned with the position of the pointer P (center of the screen). After that, the OK button 8 is pressed. Thus, the imaging location is set. The imaging location setting processing unit 50a sets a location where the pointer P is located when the OK button 8 is pressed as an imaging location setting.
　このように、本実施の形態のデジタルカメラ１では、液晶モニタ１３及び操作部４６を利用して、撮像地の設定が行われる。したがって、本実施の形態のデジタルカメラ１では、撮像地設定処理部５０ａ、液晶モニタ１３及び操作部４６が、撮像地設定部として機能する。 As described above, in the digital camera 1 of the present embodiment, the setting of the imaging location is performed using the liquid crystal monitor 13 and the operation unit 46. Therefore, in the digital camera 1 according to the present embodiment, the imaging location setting processing unit 50a, the liquid crystal monitor 13, and the operation unit 46 function as an imaging location setting unit.
　〔撮像情報取得部〕
　撮像情報取得部５０ｂは、センサ部４８の出力に基づいて、撮像情報を取得する処理を行う。具体的には、撮像方位、撮像姿勢及び撮像高さの各情報を取得する処理を行う。撮像方位及び撮像姿勢については、三軸加速度センサ４８ａ、三軸角速度センサ４８ｂ及び三軸地磁気センサ４８ｃの出力に基づいて算出する。撮像高さについては、高さセンサ４８ｄの出力に基づいて算出する。 [Imaging Information Acquisition Unit]
The imaging information acquisition unit 50 b performs processing for acquiring imaging information based on the output of the sensor unit 48. Specifically, processing of acquiring each information of imaging orientation, imaging posture, and imaging height is performed. The imaging orientation and the imaging attitude are calculated based on the outputs of the three-axis acceleration sensor 48a, the three-axis angular velocity sensor 48b, and the three-axis geomagnetic sensor 48c. The imaging height is calculated based on the output of the height sensor 48d.
　〔検索要求部〕
　検索要求部５０ｃは、インターネット２００を介して接続された検索サーバ１１０に対して、画像の検索を要求する処理を行う。検索を要求する画像は、撮像地として設定された場所から一定の範囲内で撮像され、かつ、撮像情報取得部５０ｂで取得された撮像情報と近似する撮像情報を有する画像である。検索要求部５０ｃは、撮像地設定処理部５０ａから撮像地の情報を取得し、撮像情報取得部５０ｂから撮像情報を取得する。また、取得した情報からクエリを生成し、検索サーバ１１０に送信する。 [Search request unit]
The search request unit 50 c performs a process of requesting a search of an image to the search server 110 connected via the Internet 200. The image for which the search is requested is an image having imaging information which is imaged within a certain range from the place set as the imaging location and approximates to the imaging information acquired by the imaging information acquisition unit 50b. The search request unit 50c acquires information of the imaging location from the imaging location setting processing unit 50a, and acquires imaging information from the imaging information acquisition unit 50b. Also, a query is generated from the acquired information and transmitted to the search server 110.
　なお、「設定された撮像地から一定の範囲内」とは、たとえば、設定された撮像地を中心とした半径ｒの範囲内等、撮像地を基準とした規定の範囲内を意味する。規定の範囲は、事前に設定される。たとえば、１０ｃｍに設定される。 Note that “within a certain range from the set imaging location” means within a defined range based on the imaging location, such as within the range of the radius r centered on the set imaging location. The prescribed range is set in advance. For example, it is set to 10 cm.
　また、「近似する撮像情報を有する画像」には、同じ撮像情報を有する画像も含まれる。「近似する撮像情報を有する画像」は、たとえば、撮像情報が許容範囲内の画像として規定される。この場合、撮像情報が同じ画像、及び、撮像情報が許容範囲内の画像が検索される。撮像情報には、撮像方位、撮像姿勢及び撮像高さの情報が含まれるので、そのそれぞれについて許容範囲が定められる。したがって、この場合、撮像方位、撮像姿勢及び撮像高さのそれぞれが同じ画像、及び、それぞれが許容範囲の画像が検索される。 In addition, “an image having approximate imaging information” also includes an image having the same imaging information. The “image having similar imaging information” is defined, for example, as an image in which the imaging information is within the allowable range. In this case, an image having the same imaging information and an image within the allowable range of the imaging information are searched. The imaging information includes information on the imaging orientation, the imaging attitude, and the imaging height, so the allowable range is determined for each of them. Therefore, in this case, an image having the same imaging orientation, an imaging orientation, and an imaging height, and an image having an allowable range are searched.
　〔検索結果表示処理部〕
　検索結果表示処理部５０ｄは、検索要求に対する検索サーバ１１０からの回答を受け付け、結果を液晶モニタ１３に表示させる処理を行う。すなわち、検索要求に対して検索サーバ１１０で検索された画像を取得し、液晶モニタ１３に表示させる処理を行う。 [Search result display processing unit]
The search result display processing unit 50d receives an answer from the search server 110 to the search request, and performs a process of displaying the result on the liquid crystal monitor 13. That is, an image retrieved by the retrieval server 110 in response to the retrieval request is acquired, and a process of displaying the image on the liquid crystal monitor 13 is performed.
　図８は、液晶モニタに表示される検索結果の表示の一例を示す図である。同図（Ａ）は、サムネイル表示の一例を示す図である。同図（Ｂ）は、個別表示の一例を示す図である。 FIG. 8 is a view showing an example of display of search results displayed on the liquid crystal monitor. The figure (A) is a figure which shows an example of a thumbnail display. The figure (B) is a figure which shows an example of an individual display.
　表示は、たとえば、図８（Ａ）に示すように、サムネイル形式で行われ、一画面に複数枚の画像が一覧表示される。図８（Ａ）は、一度に９枚の画像を一覧表示する場合の例を示している。一覧表示させる枚数は、たとえば、ズームキー６の操作で切り替えられる。 The display is performed, for example, in a thumbnail format as shown in FIG. 8A, and a plurality of images are displayed in a list on one screen. FIG. 8A shows an example of displaying nine images at a time as a list. The number of images to be displayed in a list can be switched by operating the zoom key 6, for example.
　また、図８（Ｂ）に示すように、表示は必要に応じて個別表示に切り替えられる。たとえば、一覧表示された画像の中から１枚の画像を選択すると、選択された画像が個別表示される。選択は、たとえば、十字ボタン７及びＯＫボタン８の操作で行われる。図８（Ａ）に示すように、サムネイル表示の際に選択用の枠ＳＦが表示される。十字ボタン７の操作で枠ＳＦを移動させ、ＯＫボタン８で選択を確定する。個別表示に切り替えられた場合は、操作部４６の操作に応じてコマ送りされる。たとえば、十字ボタン７の右ボタン又は左ボタンの操作によってコマ送りされる。 Further, as shown in FIG. 8B, the display can be switched to the individual display as needed. For example, when one image is selected from among the images displayed in a list, the selected images are individually displayed. The selection is performed, for example, by operating the cross button 7 and the OK button 8. As shown in FIG. 8A, a frame SF for selection is displayed at the time of thumbnail display. The frame SF is moved by the operation of the cross button 7, and the selection is confirmed by the OK button 8. When the display is switched to the individual display, the frame is advanced according to the operation of the operation unit 46. For example, the frame advance is performed by the operation of the right button or the left button of the cross button 7.
　〔撮像予定画像設定処理部〕
　撮像予定画像設定処理部５０ｅは、撮像予定画像を設定する処理を行う。撮像予定画像は、ユーザが撮像する予定の画像であり、検索結果として液晶モニタ１３に表示された画像の中から選択される。 [Imaging schedule image setting processing unit]
The imaging planned image setting processing unit 50e performs a process of setting an imaging planned image. The imaging scheduled image is an image scheduled to be imaged by the user, and is selected from the images displayed on the liquid crystal monitor 13 as a search result.
　図８（Ｂ）に示すように、検索結果を個別表示に切り替えると、撮像予定画像への設定を問うメッセージＭＳが同時に表示される。個別表示されている際にＯＫボタン８が押されると、表示中の画像が撮像予定画像に設定される。 As shown in FIG. 8 (B), when the search result is switched to the individual display, a message MS asking the setting to the imaging planned image is simultaneously displayed. When the OK button 8 is pressed while individually displayed, the image being displayed is set as the imaging planned image.
　撮像予定画像設定処理部５０ｅは、個別表示中にＯＫボタン８が押されると、表示中の画像を撮像予定画像として、ＥＥＰＲＯＭ４４に記録する。また、その撮像予定画像の撮像地の情報及び撮像情報を取得して、撮像予定画像に関連づけてＥＥＰＲＯＭ４４に記録する。この際、撮像予定画像設定処理部５０ｅは、撮像予定地画像の撮像地を撮像予定地、撮像予定画像の撮像情報を撮像予定情報として、ＥＥＰＲＯＭ４４に記録する。 When the OK button 8 is pressed during the individual display, the imaging scheduled image setting processing unit 50e records the image being displayed on the EEPROM 44 as the imaging scheduled image. Further, information on the imaging location of the imaging planned image and imaging information are acquired, and are stored in the EEPROM 44 in association with the imaging planned image. At this time, the imaging scheduled image setting processing unit 50e records the imaging location of the imaging planned ground image as the imaging planned location, and the imaging information of the imaging planned image as the imaging scheduled information in the EEPROM 44.
　なお、撮像地の情報及び撮像情報は、画像のタグ情報から取得する。たとえば、画像に付加されたＥｘｉｆ （Exchangeable image file format）情報から取得する。したがって、検索サーバ１１０から検索結果として送信される画像には、これらの情報が付加された画像が送信される。 Note that the information on the imaging location and the imaging information are acquired from the tag information of the image. For example, it is acquired from Exif (Exchangeable image file format) information attached to an image. Therefore, to the image transmitted as the search result from the search server 110, the image to which the information is added is transmitted.
　本実施の形態のデジタルカメラ１では、撮像予定画像設定処理部５０ｅ、液晶モニタ１３及び操作部４６が、撮像予定画像選択部として機能する。また、ＥＥＰＲＯＭ４４が、撮像予定画像情報記憶部として機能する。 In the digital camera 1 according to the present embodiment, the imaging scheduled image setting processing unit 50e, the liquid crystal monitor 13, and the operation unit 46 function as an imaging scheduled image selection unit. Further, the EEPROM 44 functions as an imaging scheduled image information storage unit.
　〔到着告知処理部〕
　到着告知処理部５０ｆは、撮像予定画像の撮像地、すなわち、撮像予定地への到着を告知する処理を行う。到着告知処理部５０ｆは、ＧＰＳ４８ｅで検出される現在地の情報に基づいて、撮像予定地に到着したか否かを判定する。ここでは、撮像予定地までの距離が閾値以下になると、撮像予定地に到着したと判定する。閾値（第１の閾値）は、ほぼ撮像予定地に到着したと認められる範囲内に設定される。たとえば、１０ｃｍに設定される。 [Arrival notification processing unit]
The arrival notification processing unit 50 f performs a process of notifying the arrival at the imaging location of the imaging scheduled image, that is, the imaging scheduled location. The arrival notification processing unit 50 f determines whether or not the imaging planned site has arrived based on the information on the current location detected by the GPS 48 e. Here, when the distance to the planned imaging location becomes equal to or less than the threshold value, it is determined that the planned imaging location has arrived. The threshold (first threshold) is set within a range that is considered to have arrived at the imaging planned site. For example, it is set to 10 cm.
　到着告知処理部５０ｆは、撮像予定地に到着したと判定すると、到着を告知する処理を行う。具体的には、撮像予定地に到着したことを示す情報を液晶モニタ１３に表示する処理を行う。たとえば、到着を告げるメッセージを液晶モニタ１３に表示させる。これと同時に、撮像予定地に到着したことを示す情報をスピーカー１４から音声で出力する処理を行う。たとえば、到着を告げるメッセージを音声で出力したり、到着を表わすメロディ等を出力したりする。 When it is determined that the arrival at the imaging planned site has arrived, the arrival notification processing unit 50f performs processing for notifying of arrival. Specifically, a process of displaying on the liquid crystal monitor 13 information indicating arrival at the imaging planned site is performed. For example, a message indicating arrival is displayed on the liquid crystal monitor 13. At the same time, processing is performed to output information indicating the arrival at the imaging planned site by voice from the speaker 14. For example, a message indicating arrival is output by voice, and a melody indicating arrival is output.
　〔接近告知処理部〕
　接近告知処理部５０ｇは、撮像予定地に接近したことを告知する処理を行う。接近告知処理部５０ｇは、撮像予定地までの距離が閾値（第２の閾値）以下になると、撮像予定地に接近したと判定し、その旨を告知する。たとえば、現在地から撮像予定地までの直線距離が閾値以下になると、撮像予定地に接近したと判定し、その旨を告知する。接近告知処理部５０ｇは、ＧＰＳ４８ｅで検出される現在地の情報に基づいて、撮像予定地までの距離が閾値以下になったか否かを判定する。 [Approach notice processing unit]
The approach notification processing unit 50g performs a process of notifying that the imaging planned site has been approached. When the distance to the planned imaging location becomes equal to or less than the threshold (second threshold), the approach notification processing unit 50 g determines that the planned imaging location is approached, and notifies that effect. For example, when the linear distance from the current location to the planned imaging location becomes equal to or less than the threshold value, it is determined that the planned imaging location is approached, and that effect is notified. The approach notification processing unit 50g determines whether the distance to the planned imaging location has become equal to or less than a threshold value, based on the information on the current location detected by the GPS 48e.
　接近したことの告知は、撮像予定地に接近したことを示す情報を液晶モニタ１３に表示することにより行われる。たとえば、接近を告げるメッセージを液晶モニタ１３に表示させる。これと同時に、撮像予定地に接近したことを示す情報をスピーカー１４から音声で出力する。たとえば、接近を告げるメッセージを音声で出力したり、接近を表わすメロディ等を出力したりする。 The notification of the approach is performed by displaying on the liquid crystal monitor 13 information indicating the approach to the imaging planned site. For example, a message indicating an approach is displayed on the liquid crystal monitor 13. At the same time, information indicating that the image pickup planned site has approached is output by voice from the speaker 14. For example, a message indicating the approach is output as a voice, or a melody indicating the approach is output.
　なお、ここでの告知は、撮像予定地に近くまで来ていること告知するものであるため、閾値（第２の閾値）は、撮像予定地の近くと認められる範囲内に設定される。たとえば、１００ｍに設定される。第２の閾値については、あらかじめ定められる。 In addition, since the notification here is to notify that it has come close to the imaging planned site, the threshold (second threshold) is set within a range recognized as being close to the imaging planned site. For example, it is set to 100 m. The second threshold is predetermined.
　〔撮像予定地案内情報告知処理部〕
　撮像予定地案内情報告知処理部５０ｈは、撮像予定地までの案内情報を告知する処理を行う。本実施の形態のデジタルカメラ１では、撮像予定地までの案内情報として、現在地から撮像予定地までの距離及び方位の情報を告知する。撮像予定地案内情報告知処理部５０ｈは、センサ部４８の出力に基づいて、現在地から撮像予定地までの距離及び現在地を基準とした撮像予定地の方位を求め、その結果を告知する。距離は、たとえば、現在地から撮像予定地までの直線距離を求めて告知する。 [Imaging planned place guidance information notification processing unit]
The imaging planned location guidance information notification processing unit 50 h performs processing of notifying the guidance information to the imaging planned location. The digital camera 1 according to the present embodiment announces information on the distance from the current location to the planned imaging location and the direction as guidance information on the planned imaging location. The planned imaging location guidance information notification processing unit 50h determines the distance from the current location to the planned imaging location and the direction of the planned imaging location based on the current location based on the output of the sensor unit 48, and announces the result. The distance is notified by, for example, obtaining a linear distance from the current location to the planned imaging location.
　撮像予定地案内情報告知処理部５０ｈは、現在地から撮像予定地までの距離が閾値（第２の閾値）以下となった場合に当該告知処理を実施する。したがって、接近の告知後に実施される。 The planned imaging location guidance information notification processing unit 50 h performs the notification process when the distance from the current location to the planned imaging location becomes equal to or less than a threshold (second threshold). Therefore, it is implemented after the notification of approach.
　撮像予定地までの案内情報の告知の処理は、現在地から撮像予定地までの距離及び方位の情報を液晶モニタ１３に表示することにより行う。 The process of notifying the guidance information to the imaging planned site is performed by displaying on the liquid crystal monitor 13 the information of the distance from the current site to the imaging planned site and the azimuth.

The imaging setting completion notification processing unit 50i performs processing of notifying that the setting of the digital camera 1 is completed on the imaging planned site. The setting of the digital camera 1 being completed means that the digital camera 1 has been set in almost the same state as when the imaging scheduled image was captured. This means that the imaging orientation, the imaging attitude, and the imaging height at the time of imaging the imaging planned image substantially coincide.
　撮像設定完了告知処理部５０ｉは、撮像情報取得部５０ｂで取得される撮像情報と撮像予定画像の撮像情報、すなわち、撮像予定情報との差分が閾値以下となった場合に、撮像設定の完了と判定し、その旨を告知する。撮像情報には、撮像方位、撮像姿勢及び撮像高さが含まれるので、閾値（第３の閾値）は、そのそれぞれについて規定される。すなわち、撮像方位についての閾値、撮像姿勢についての閾値、及び、撮像高さについての閾値が規定される。すべての項目についての差分が閾値以下となった場合に、撮像設定の完了と判定される。 When the difference between the imaging information acquired by the imaging information acquiring unit 50b and the imaging information of the imaging planned image, that is, the imaging planned information, becomes equal to or less than the threshold, the imaging setting completion notification processing unit 50i Determine and announce that. Since the imaging information includes the imaging orientation, the imaging attitude, and the imaging height, the threshold (third threshold) is defined for each of them. That is, a threshold for the imaging orientation, a threshold for the imaging orientation, and a threshold for the imaging height are defined. When the difference for all the items becomes equal to or less than the threshold value, it is determined that the imaging setting is completed.
　撮像設定完了を告知する処理は、たとえば、撮像設定の完了を示す情報を液晶モニタ１３に表示することにより行われる。たとえば、設定完了を告げるメッセージを液晶モニタ１３に表示させることにより行われる。また、これと同時に撮像設定の完了を示す情報をスピーカー１４から音声で出力することにより行われる。たとえば、設定完了を告げるメッセージを音声で出力したり、設定完了を表わすメロディ等を出力したりすることにより行われる。 The process of notifying the imaging setting completion is performed, for example, by displaying information indicating the completion of the imaging setting on the liquid crystal monitor 13. For example, it is performed by displaying a message indicating the completion of setting on the liquid crystal monitor 13. At the same time, information indicating the completion of the imaging setting is output from the speaker 14 as a voice. For example, it is performed by outputting a message telling the setting completion by voice or outputting a melody indicating the setting completion.
　なお、設定完了の告知は、撮像予定地への到着が前提とされる。したがって、現在地から撮像予定地までの距離が第１の閾値以下であることが前提とされる。 Note that notification of setting completion is premised on arrival at a planned imaging site. Therefore, it is assumed that the distance from the current location to the planned imaging location is equal to or less than the first threshold.

　撮像設定案内情報告知処理部５０ｊは、撮像予定地に到着した場合において、撮像設定の案内情報を告知する処理を行う。本実施の形態のデジタルカメラ１では、撮像情報取得部５０ｂで取得される撮像情報と撮像予定情報との差分を撮像設定案内情報として告知する。撮像情報取得部５０ｂでは、撮像情報として、撮像方位、撮像姿勢及び撮像高さの情報が取得されるので、撮像設定案内情報告知処理部５０ｊは、その各々の差分を求めて、個別に告知する。すなわち、撮像方位の差分、撮像姿勢の差分及び撮像高さの差分を求めて、個別に告知する。告知の処理は、たとえば、差分の情報を液晶モニタ１３に表示することにより行われる。 [Imaging setting guidance information notification processing unit]
The imaging setting guidance information notification processing unit 50j performs processing of notifying guidance information of imaging settings when arriving at the imaging planned site. In the digital camera 1 according to the present embodiment, the difference between the imaging information acquired by the imaging information acquiring unit 50b and the imaging schedule information is notified as imaging setting guide information. In the imaging information acquisition unit 50b, information on imaging orientation, imaging attitude, and imaging height is acquired as imaging information, so the imaging setting guide information notification processing unit 50j finds the difference between the information and individually notifies it. . That is, the difference of the imaging direction, the difference of the imaging posture, and the difference of the imaging height are determined and notified individually. The notification process is performed, for example, by displaying difference information on the liquid crystal monitor 13.

　デジタルカメラ１のモードが画像検索モードに設定されると、まず、撮像地の設定処理が行われる（ステップＳ１０）。カメラ制御部５０は、撮像地の設定画面を液晶モニタ１３に表示し（図７参照）、ユーザから撮像地の設定を受け付ける。 When the mode of the digital camera 1 is set to the image search mode, first, processing for setting an imaging location is performed (step S10). The camera control unit 50 displays the setting screen of the imaging location on the liquid crystal monitor 13 (see FIG. 7), and receives the setting of the imaging location from the user.
　撮像地の設定が終了すると、シャッターボタン５の押下の有無が判定される（ステップＳ１１）。カメラ制御部５０は、操作部４６からの出力に基づいて、シャッターボタン５の押下の有無を判定する。 When the setting of the imaging location is completed, it is determined whether or not the shutter button 5 is pressed (step S11). The camera control unit 50 determines whether or not the shutter button 5 is pressed based on the output from the operation unit 46.
　シャッターボタン５が押されたと判定すると、撮像情報が取得される（ステップＳ１２）。すなわち、撮像方位、撮像姿勢及び撮像高さの各情報が取得される。カメラ制御部５０は、センサ部４８の出力に基づいて、撮像情報を取得する。 If it is determined that the shutter button 5 has been pressed, imaging information is acquired (step S12). That is, each information of an imaging direction, an imaging attitude, and an imaging height is acquired. The camera control unit 50 acquires imaging information based on the output of the sensor unit 48.
　撮像情報が取得されると、次に、検索対象が設定される（ステップＳ１３）。検索対象には、撮像地として設定された場所から一定の範囲内で撮像され、かつ、取得された撮像情報と近似する撮像情報を有する画像が設定される。具体的には、撮像地として設定された場所を中心とした半径ｒの範囲で撮像され、かつ、撮像方位、撮像姿勢及び撮像高さの各情報が許容範囲内の画像が検索対象として設定される。半径ｒは、あらかじめ定められた値である。また、許容範囲もあらかじめ定められ、かつ、撮像方位、撮像姿勢及び撮像高さのそれぞれについて個別に定められる。 When the imaging information is acquired, next, a search target is set (step S13). As a search target, an image having imaging information which is imaged within a certain range from a place set as an imaging location and approximates to the acquired imaging information is set. Specifically, the image is captured within a range of radius r centered on the location set as the imaging location, and each information of imaging orientation, imaging posture, and imaging height is set as a search target image Ru. The radius r is a predetermined value. Further, the allowable range is also determined in advance, and is individually determined for each of the imaging orientation, the imaging attitude, and the imaging height.
　検索対象が設定されると、外部の検索サーバ１１０に対して、検索要求の処理が行われる（ステップＳ１４）。カメラ制御部５０は、インターネット２００を介して、検索サーバ１１０と通信し、検索サーバ１１０に対して、対象の検索を要求する。 When the search target is set, processing of a search request is performed on the external search server 110 (step S14). The camera control unit 50 communicates with the search server 110 via the Internet 200, and requests the search server 110 to search for a target.
　検索サーバ１１０は、デジタルカメラ１からの検索要求を受け付けて、検索処理を実行する。すなわち、要求に合致する画像を画像ＤＢ１１２から検索し、検索された画像をデジタルカメラ１に送信する。 The search server 110 receives a search request from the digital camera 1 and executes a search process. That is, an image matching the request is searched from the image DB 112, and the searched image is transmitted to the digital camera 1.
　カメラ制御部５０は、検索サーバ１１０から検索結果を受信すると、その結果の表示処理を実行する（ステップＳ１５）。すなわち、検索の結果として得られた画像を液晶モニタ１３に表示させる（図８参照）。 When receiving the search result from the search server 110, the camera control unit 50 executes display processing of the result (step S15). That is, the image obtained as a result of the search is displayed on the liquid crystal monitor 13 (see FIG. 8).
　検索結果が液晶モニタ１３に表示されると、撮像予定画像の選択の有無が判定される（ステップＳ１６）。上記のように、撮像予定画像は、検索結果の画像を個別表示した後、ＯＫボタン８を押下することにより行われる（図８参照）。カメラ制御部５０は、操作部４６から出力に基づいて、撮像予定画像の選択の有無を判定する。 When the search result is displayed on the liquid crystal monitor 13, it is determined whether or not the imaging scheduled image is selected (step S16). As described above, the imaging scheduled image is performed by pressing the OK button 8 after individually displaying the search result images (see FIG. 8). The camera control unit 50 determines the presence or absence of the selection of the imaging scheduled image based on the output from the operation unit 46.
　撮像予定画像の選択なし、と判定すると、カメラ制御部５０は、画像検索の終了指示の有無を判定する（ステップＳ１８）。なお、画像検索は、他のモードに切り替えられた場合、デジタルカメラ１の電源がオフにされた場合に終了する。カメラ制御部５０は、操作部４６からの出力に基づいて、画像検索の終了指示の有無を判定する。カメラ制御部５０は、画像検索の終了指示あり、と判定すると、画像の検索処理を終了する。画像検索の終了指示なし、と判定すると、ステップＳ１１に戻り、シャッターボタン５の押下の有無が判定する。したがって、再度シャッターボタン５が押下された場合は、再度検索が実施される。 If it is determined that the imaging scheduled image is not selected, the camera control unit 50 determines the presence or absence of an instruction to end the image search (step S18). The image search ends when the digital camera 1 is turned off when the mode is switched to another mode. The camera control unit 50 determines the presence or absence of an instruction to end the image search based on the output from the operation unit 46. If it is determined that the image search end instruction is issued, the camera control unit 50 ends the image search process. If it is determined that there is no instruction to end the image search, the process returns to step S11, and it is determined whether or not the shutter button 5 is pressed. Therefore, when the shutter button 5 is pressed again, the search is performed again.
　上記ステップＳ１６において、撮像予定画像の選択あり、と判定すると、撮像予定画像の設定処理が行われる（ステップＳ１７）。カメラ制御部５０は、選択された画像（液晶モニタ１３に表示中の画像）を撮像予定画像としてＥＥＰＲＯＭに記録する。また、その撮像予定画像の撮像地の情報及び撮像情報を取得し、撮像予定画像に関連づけて、ＥＥＰＲＯＭ４４に記録する。この際、カメラ制御部５０は、撮像予定画像の撮像地を撮像予定地、撮像情報を撮像予定情報として、ＥＥＰＲＯＭ４４に記録する。撮像予定画像の設定が完了すると、画像検索処理は終了する。 If it is determined in step S16 that the imaging scheduled image is selected, setting processing of the imaging scheduled image is performed (step S17). The camera control unit 50 records the selected image (the image being displayed on the liquid crystal monitor 13) in the EEPROM as an imaging scheduled image. Also, information on the imaging location of the imaging scheduled image and imaging information are acquired, and are stored in the EEPROM 44 in association with the imaging scheduled image. At this time, the camera control unit 50 records the imaging location of the imaging scheduled image as the imaging scheduled location and the imaging information in the EEPROM 44 as imaging schedule information. When the setting of the imaging scheduled image is completed, the image search process ends.
　このように、画像検索機能は、撮像地を設定して、シャッターボタン５を押すと、設定された撮像地から一定の範囲内で撮像され、かつ、撮像情報取得部５０ｂで取得された撮像情報と近似する撮像情報を有する画像が検索される。検索された画像は、液晶モニタ１３に表示される。したがって、液晶モニタ１３に表示された画像を確認することにより、撮像地で撮像できる画像を確認できる。また、撮像方位、撮像姿勢及び撮像高さに対応して画像が検索されるので、あたかもその場で撮像しているかのような感覚で画像を検索できる。これにより、その場に居ながら現地での撮像をシミュレーションできる。 As described above, when the image search function sets the imaging location and presses the shutter button 5, the imaging information acquired within a certain range from the set imaging location and acquired by the imaging information acquisition unit 50b An image having imaging information that approximates to is searched. The retrieved image is displayed on the liquid crystal monitor 13. Therefore, by confirming the image displayed on the liquid crystal monitor 13, it is possible to confirm the image that can be picked up at the imaging location. In addition, since the image is retrieved corresponding to the imaging orientation, the imaging orientation, and the imaging height, the image can be retrieved as if imaging is performed on the spot. This makes it possible to simulate on-site imaging while staying on the spot.
　［撮像予定地案内機能］
　撮像予定地案内機能とは、撮像予定画像として選択された画像の撮像地（撮像予定地）に案内する機能である。 [Imaging planned location guidance function]
The imaging planned site guidance function is a function for guiding to the imaging site (imaging planned site) of the image selected as the imaging planned image.
　撮像予定地案内機能は、当該機能をオンにすることで有効化される。撮像予定地案内機能のオン、オフの切り替えは、撮像予定地案内機能のオン、オフの設定画面で行われる。ユーザは、メニュー画面から撮像予定地案内機能のオン、オフの設定画面を呼び出し、撮像予定地案内機能のオン、オフを設定する。 The imaging planned location guidance function is activated by turning on the function. Switching of the imaging planned location guidance function on and off is performed on the setting screen of the imaging planned location guidance function on and off. The user calls the on / off setting screen for the imaging planned location guidance function from the menu screen, and sets the imaging planned location guidance function on or off.
　図１３は、撮像予定地の案内処理の手順を示すフローチャートである。 FIG. 13 is a flowchart showing the procedure of guidance processing of the imaging planned site.
　撮像予定画像の選択処理が行われる（ステップＳ２０）。すなわち、撮像地までの案内を希望する撮像予定画像の選択を受け付ける処理が行われる。なお、当該処理は、撮像予定画像が、ＥＥＰＲＯＭ４４に複数枚記録されている場合の処理である。撮像予定画像が１枚しか記録されない場合、当該処理は不要となる。選択は、たとえば、ＥＥＰＲＯＭ４４に記録されている撮像予定画像を液晶モニタ１３に一覧表示させ、その中から１枚をユーザに選択させることにより行われる。画像が選択されると、選択された画像の撮像予定地の情報及び撮像予定情報が取得され、案内すべき撮像予定地及び撮像予定情報として設定され、ＥＥＰＲＯＭ４４に記録される。 A selection process of an imaging scheduled image is performed (step S20). That is, a process of accepting the selection of the imaging scheduled image for which guidance to the imaging location is desired is performed. The process is a process when a plurality of imaging planned images are recorded in the EEPROM 44. When only one image to be captured is recorded, the process is unnecessary. The selection is performed, for example, by displaying a list of imaging scheduled images recorded in the EEPROM 44 on the liquid crystal monitor 13 and allowing the user to select one of them. When an image is selected, information on a planned imaging location of the selected image and imaging schedule information are acquired, set as a planned imaging location to be guided and imaging schedule information, and recorded in the EEPROM 44.
　撮像予定画像が選択され、撮像予定地案内機能がオンにされると、撮像予定地の案内の処理が開始される。 When the imaging planned image is selected and the imaging planned location guidance function is turned on, processing of guidance of the imaging planned location is started.
　まず、デジタルカメラ１の現在地の情報が取得される（ステップＳ２１）。カメラ制御部５０は、ＧＰＳ４８ｅの出力に基づいて、デジタルカメラ１の現在地の情報を取得する。 First, information on the current location of the digital camera 1 is acquired (step S21). The camera control unit 50 acquires information on the current location of the digital camera 1 based on the output of the GPS 48 e.
　次に、現在地から撮像予定地までの距離が閾値（第２の閾値）以下か否かが判定される（ステップＳ２２）。すなわち、撮像予定地から一定範囲内の距離まで近づいたか否かが判定される。カメラ制御部５０は、取得した現在地の情報と撮像予定地の情報とに基づいて、現在地から撮像予定地までの距離が閾値（第２の閾値）以下になったか否かを判定する。 Next, it is determined whether the distance from the current location to the planned imaging location is less than or equal to a threshold (second threshold) (step S22). That is, it is determined whether or not the distance from the planned imaging location has approached to a certain range. The camera control unit 50 determines whether the distance from the current location to the planned imaging location has become equal to or less than a threshold (second threshold) based on the acquired information on the current location and the information on the planned imaging location.
　現在地から撮像予定地までの距離が閾値（第２の閾値）以下になると、撮像予定地に接近したことが告知される（ステップＳ２３）。すなわち、その旨が液晶モニタ１３に表示され、かつ、スピーカー１４から音声で告知される。 When the distance from the current location to the planned imaging location becomes equal to or less than the threshold (second threshold), it is notified that the planned imaging location has approached (step S23). That is, the fact is displayed on the liquid crystal monitor 13 and notified by voice from the speaker 14.
　接近の告知が行われると、撮像予定地までの案内情報の告知処理が開始される（ステップＳ２４）。撮像予定地までの案内の告知処理は、現在地から撮像予定地までの距離及び方位の情報を液晶モニタ１３に表示することにより行われる（図９参照）。 When notification of approach is performed, notification processing of guidance information to the imaging planned site is started (step S24). Notification processing of guidance to the imaging planned site is performed by displaying information on the distance from the current site to the imaging planned site and the direction on the liquid crystal monitor 13 (see FIG. 9).
　この後、撮像予定地に到着したか否かが判定される（ステップＳ２５）。撮像予定地に到着したか否かは、現在地の情報と撮像予定地の情報とに基づいて判定される。本実施の形態のデジタルカメラ１では、現在地から撮像予定地までの距離が、閾値（第１の閾値）以下になった場合に、撮像予定地に到着したと判定する。したがって、カメラ制御部５０は、取得した現在地の情報と撮像予定地の情報とに基づいて、現在地から撮像予定地までの距離が閾値（第１の閾値）以下になったか否かを判定して、撮像予定地に到着したか否かを判定する。 Thereafter, it is determined whether or not the imaging planned site has arrived (step S25). It is determined based on the information on the present location and the information on the planned imaging location whether or not the imaging planned location has arrived. In the digital camera 1 of the present embodiment, when the distance from the current location to the planned imaging location becomes equal to or less than the threshold (first threshold), it is determined that the planned imaging location has arrived. Therefore, the camera control unit 50 determines whether the distance from the current location to the planned imaging location has become equal to or less than a threshold (first threshold) based on the acquired current location information and the planned imaging location information. , It is determined whether it has arrived at the imaging planned site.
　到着していないと判定されると、継続して撮像予定地までの案内情報の告知処理が実施される（ステップＳ２４）。 If it is determined that it has not arrived, notification processing of guidance information to the planned imaging location is continuously performed (step S24).
　一方、到着したと判定されると、到着が告知される（ステップＳ２６）。すなわち、撮像予定地に到着したことを示す情報が液晶モニタ１３に表示される。また、撮像予定地に到着したことを示す情報がスピーカー１４から音声で出力される。 On the other hand, when it is determined that it has arrived, arrival is notified (step S26). That is, information indicating arrival at the imaging planned site is displayed on the liquid crystal monitor 13. Also, information indicating that the image has arrived at the imaging planned site is output from the speaker 14 as voice.
　撮像予定地に到着すると、撮像予定地への案内の処理は終了する。また、案内の終了と同時に撮像予定地案内機能がオフされる。 When arriving at the planned imaging site, the process of guiding to the planned imaging site ends. Further, the planned imaging location guidance function is turned off simultaneously with the end of the guidance.
　このように、撮像予定地案内機能を使用することにより、撮像予定画像が撮像された場所に容易にアクセスできる。 As described above, by using the planned imaging location guidance function, it is possible to easily access the location at which the planned imaging image was captured.
　［撮像設定案内機能］
　撮像設定案内機能とは、撮像予定地において、撮像予定画像と同じ画像を撮像するための案内をする機能である。具体的には、デジタルカメラ１の撮像方位、撮像姿勢及び撮像高さを撮像予定画像の撮像方位、撮像姿勢及び撮像高さと一致させるための案内を行う。 [Imaging setting guide function]
The imaging setting guide function is a function to provide guidance for imaging the same image as the imaging planned image at the imaging planned site. Specifically, guidance for making the imaging orientation, the imaging attitude, and the imaging height of the digital camera 1 match the imaging orientation, the imaging attitude, and the imaging height of the imaging planned image is performed.
　撮像設定案内機能は、当該機能をオンにすることで有効化される。撮像設定案内機能のオン、オフの切り替えは、撮像設定案内機能のオン、オフの設定画面で行われる。ユーザは、メニュー画面から撮像設定案内機能のオン、オフの設定画面を呼び出し、撮像設定案内機能のオン、オフを設定する。 The imaging setting guide function is activated by turning on the function. The on / off switching of the imaging setting guide function is performed on the on / off setting screen of the imaging setting guide function. The user calls up the setting screen of on / off of the imaging setting guide function from the menu screen, and sets on / off of the imaging setting guide function.
　図１４は、撮像設定案内処理の手順を示すフローチャートである。 FIG. 14 is a flowchart showing the procedure of the imaging setting guide process.
　まず、デジタルカメラ１の現在地の情報が取得される（ステップＳ３０）。カメラ制御部５０は、ＧＰＳ４８ｅの出力に基づいて、デジタルカメラ１の現在地の情報を取得する。 First, information on the current location of the digital camera 1 is acquired (step S30). The camera control unit 50 acquires information on the current location of the digital camera 1 based on the output of the GPS 48 e.
　次に、撮像予定地に到着したか否かが判定される（ステップＳ３１）。カメラ制御部５０は、取得した現在地の情報と撮像予定地の情報とに基づいて、現在地から撮像予定地までの距離が閾値（第１の閾値）以下になったか否かを判定して、撮像予定地に到着したか否かを判定する。 Next, it is determined whether it has arrived at the imaging planned site (step S31). The camera control unit 50 determines whether the distance from the current location to the planned imaging location is equal to or less than a threshold (first threshold) based on the acquired information on the current location and the information on the planned imaging location, and performs imaging. Determine if you have arrived at the planned site.
　撮像予定地に到着したと判定されると、まず、デジタルカメラ１の撮像情報が取得される（ステップＳ３２）。すなわち、センサ部４８の出力に基づいて、撮像方位、撮像姿勢及び撮像高さの各情報が取得される。 If it is determined that the intended imaging site has arrived, imaging information of the digital camera 1 is acquired first (step S32). That is, based on the output of the sensor unit 48, each information of the imaging direction, the imaging attitude, and the imaging height is acquired.
　次に、取得した撮像情報に基づいて、撮像の設定が完了したか否かが判定される（ステップＳ３３）。すなわち、デジタルカメラ１の撮像方位、撮像姿勢及び撮像高さが、撮像予定画像の撮像方位、撮像姿勢及び撮像高さに合わされたか否かが判定される。カメラ制御部５０は、取得した撮像情報と撮像予定情報との差分を求め、その差分が閾値（第３の閾値）以下か否かを判定して、撮像の設定が完了したか否かを判定する。差分が閾値（第３の閾値）以下の場合、デジタルカメラ１の撮像情報が撮像予定情報と一致したものとみなして、設定完了と判定する。閾値（第３の閾値）は、撮像方位、撮像姿勢及び撮像高さのそれぞれについて個別に設定される。したがって、カメラ制御部５０は、撮像方位、撮像姿勢及び撮像高さの全てが、閾値（第３の閾値）以下となった場合に、撮像の設定が完了した、と判定する。 Next, based on the acquired imaging information, it is determined whether the setting of imaging has been completed (step S33). That is, it is determined whether the imaging orientation, the imaging attitude, and the imaging height of the digital camera 1 are adjusted to the imaging orientation, the imaging attitude, and the imaging height of the imaging planned image. The camera control unit 50 obtains the difference between the acquired imaging information and the imaging schedule information, determines whether the difference is equal to or less than the threshold (third threshold), and determines whether the setting of imaging is completed. Do. If the difference is equal to or less than the threshold (third threshold), the imaging information of the digital camera 1 is regarded as coincident with the imaging schedule information, and it is determined that the setting is completed. The threshold (third threshold) is individually set for each of the imaging orientation, the imaging attitude, and the imaging height. Therefore, the camera control unit 50 determines that the setting of the imaging is completed when all the imaging orientation, the imaging posture, and the imaging height become equal to or less than the threshold (third threshold).
　ステップＳ３３において、撮像の設定が完了していないと判定されると、撮像設定案内情報の告知処理が行われる（ステップＳ３５）。カメラ制御部５０は、取得した撮像情報と撮像予定情報との差分を求め、その差分の情報を撮像設定案内情報として液晶モニタ１３に表示する。差分は、撮像方位、撮像姿勢及び撮像高さのそれぞれについて求められ、個別に表示される（図１０参照）。ユーザは、液晶モニタ１３の表示を見て、デジタルカメラ１の方位、姿勢、高さを修正する。撮像設定案内情報の告知処理は、撮像の設定が完了するまで繰り返し実施される。 If it is determined in step S33 that the setting of imaging has not been completed, notification processing of imaging setting guide information is performed (step S35). The camera control unit 50 obtains the difference between the acquired imaging information and the imaging schedule information, and displays the information of the difference on the liquid crystal monitor 13 as imaging setting guide information. The difference is obtained for each of the imaging direction, the imaging attitude, and the imaging height, and is individually displayed (see FIG. 10). The user looks at the display on the liquid crystal monitor 13 and corrects the direction, attitude, and height of the digital camera 1. The notification process of the imaging setting guide information is repeatedly performed until the setting of imaging is completed.
　一方、ステップＳ３３において、撮像の設定が完了したと判定されると、撮像設定完了が告知される（ステップＳ３４）。すなわち、撮像設定の完了を示す情報が液晶モニタ１３に表示される。また、撮像設定の完了を示す情報がスピーカー１４から音声で出力される。これにより、ユーザは撮像の設定が完了したことを認識できる。この後、ユーザは、撮像処理を実施する。これにより、撮像予定画像と同じ画像、又は、ほぼ同じを撮像できる。 On the other hand, when it is determined in step S33 that the setting of imaging is completed, the completion of imaging setting is notified (step S34). That is, the information indicating the completion of the imaging setting is displayed on the liquid crystal monitor 13. Further, information indicating the completion of the imaging setting is output from the speaker 14 as a voice. Thereby, the user can recognize that the setting of imaging has been completed. After this, the user performs an imaging process. In this way, it is possible to capture the same image as the to-be-captured image or almost the same image.
　このように、撮像設定案内機能を使用することにより、撮像予定画像と同じ画像を簡単に撮像できる。これにより、ベストショットの確度を高めることができる。 Thus, by using the imaging setting guide function, it is possible to easily capture the same image as the imaging planned image. This can increase the accuracy of the best shot.
　《撮像機能》
　デジタルカメラ１は、撮像モードに設定することにより、画像の撮像が可能になる。撮像モードへの切り替えは、モードの設定画面で行われる。ユーザは、メニュー画面からモードの設定画面を呼び出し、デジタルカメラ１のモードを設定する。 << Imaging function >>
The digital camera 1 can capture an image by setting the imaging mode. Switching to the imaging mode is performed on the mode setting screen. The user calls the mode setting screen from the menu screen and sets the mode of the digital camera 1.
　撮像モードに設定されると、液晶モニタ１３にライブビューが表示される。ユーザは、液晶モニタ１３の表示を見て、画角、焦点状態を確認する。撮像予定地に位置している場合において、撮像案内機能がオンされている場合、ライブビューに重ねて撮像設定案内情報が表示される。撮像予定画像を撮像する場合、ユーザは、液晶モニタ１３の表示を見て、デジタルカメラ１の姿勢等を修正し、撮像を実行する。 When the imaging mode is set, the live view is displayed on the liquid crystal monitor 13. The user looks at the display on the liquid crystal monitor 13 and confirms the angle of view and the focus state. When the imaging guidance function is turned on in the case where the imaging planned location is located, the imaging setting guidance information is displayed superimposed on the live view. When capturing a scheduled imaging image, the user looks at the display on the liquid crystal monitor 13, corrects the attitude or the like of the digital camera 1, and executes imaging.
　撮像の実行指示は、シャッターボタン５で行われる。シャッターボタン５が押されると、記録用の画像が撮像され、メモリカード３６に記録される。 The execution instruction of imaging is performed by the shutter button 5. When the shutter button 5 is pressed, an image for recording is taken and recorded on the memory card 36.
　《再生機能》
　デジタルカメラ１は、再生モードに設定することにより、メモリカード３６に記録された画像の再生が可能になる。再生モードへの切り替えは、モードの設定画面で行われる。ユーザは、メニュー画面からモードの設定画面を呼び出し、デジタルカメラ１のモードを設定する。 << playback function >>
The digital camera 1 can play back the image recorded on the memory card 36 by setting the playback mode. Switching to the reproduction mode is performed on the mode setting screen. The user calls the mode setting screen from the menu screen and sets the mode of the digital camera 1.
　再生モードに設定されると、最後に記録された画像が、メモリカード３６から読み出され、液晶モニタ１３に表示される。表示される画像は、操作部４６の操作に応じて、コマ送り、拡大、縮小等される。 When the reproduction mode is set, the image recorded last is read from the memory card 36 and displayed on the liquid crystal monitor 13. The displayed image is frame-by-frame advance, enlargement, reduction, etc. in accordance with the operation of the operation unit 46.
　［変形例］
　《撮像地の設定の変形例》
　上記実施の形態では、地図上で特定の場所を指定して、撮像地を設定しているが、撮像地を設定する方法は、これに限定されるものではない。この他、たとえば、住所を入力して、撮像地を設定してもよい。また、地名、都市名等を入力して、撮像地を指定してもよい。更に、施設名（たとえば、東京タワーなど）を入力して撮像地を指定してもよい。 [Modification]
<< Modification of setting of imaging location >>
In the above-mentioned embodiment, although a specific place is specified on a map and an imaging place is set, a method of setting an imaging place is not limited to this. Besides this, for example, an address may be input to set an imaging location. In addition, a place name, a city name, etc. may be input to designate an imaging place. Furthermore, a facility name (for example, Tokyo Tower etc.) may be input to designate an imaging location.
　また、地図上で撮像地を指定する場合は、地図データは、デジタルカメラに内蔵されていてもよいし、外部のサーバから取得する構成としてもよい。 In addition, in the case of specifying the imaging location on the map, the map data may be built in the digital camera, or may be acquired from an external server.
　《撮像情報の取得の変形例》
　〈センサ構成〉
　上記実施の形態では、三軸加速度センサ４８ａ、三軸角速度センサ４８ｂ及び三軸地磁気センサ４８ｃの出力に基づいて、撮像方位及び撮像姿勢の情報を取得しているが、撮像方位及び撮像姿勢の情報を取得する手段は、これに限定されるものではない。公知の手法を用いて取得できる。 << Modification of acquisition of imaging information >>
<Sensor configuration>
In the above embodiment, the information of the imaging direction and the imaging attitude is acquired based on the outputs of the three-axis acceleration sensor 48a, the three-axis angular velocity sensor 48b, and the three-axis geomagnetic sensor 48c. The means of acquiring is not limited to this. It can be obtained using a known method.
　また、上記実施の形態では、気圧から高さを求める構成としているが、撮像高さの情報を取得する手段（高さ検出部）は、これに限定されるものではない。たとえば、測距センサを用いて、基準面（たとえば、地面）からの高さを測定する構成とすることもできる。この場合、測距センサには、赤外線方式、レーザ方式、超音波方式等の公知の非接触方式の測距センサを用いることができる。また、ＴｏＦ（Time of Flight）方式で対象物までの距離を測定する測距センサ等を用いることもできる。 In the above-described embodiment, the height is obtained from the air pressure, but the means (height detection unit) for acquiring the information of the imaging height is not limited to this. For example, a distance measuring sensor may be used to measure the height from a reference surface (e.g., the ground). In this case, as a distance measurement sensor, a known non-contact distance measurement sensor such as an infrared method, a laser method, and an ultrasonic method can be used. Further, it is possible to use a distance measuring sensor or the like which measures the distance to the object by the ToF (Time of Flight) method.

　同図に示すように、本例のデジタルカメラ１ａは、カメラボディ２の底部２ｂに測距センサ４９ｂを備えている。底部２ｂは、横位置で撮像する際に鉛直下側に位置する部位である。測距センサ４９ｂは、レーザ方式の測距センサであり、カメラボディ２の底面に備えられた測距窓（不図示）からレーザ光を出射して、対象物までの距離を測定する。ここでは、地面までの距離を測定して、高さを測定する。 As shown in the figure, the digital camera 1 a of the present example is provided with a distance measurement sensor 49 b at the bottom 2 b of the camera body 2. The bottom portion 2 b is a portion positioned vertically below when imaging in the lateral position. The distance measurement sensor 49 b is a laser type distance measurement sensor, emits laser light from a distance measurement window (not shown) provided on the bottom surface of the camera body 2, and measures the distance to the object. Here, the distance to the ground is measured to measure the height.
