(Schematic configuration of the full scale display system 100)
First, a schematic configuration of the actual size display system 100 according to the embodiment of the present invention will be described. FIG. 1 is a block diagram showing a schematic configuration of an actual size display system according to an embodiment of the present invention. The full scale display system 100 according to the embodiment includes a content distribution device 110 and a display device 120. The content distribution device 110 is installed in, for example, a television station or an internet provider. The display device 120 is installed in a general household, for example.

  The content distribution device 110 distributes content including image data and actual size data of an object in the image data. Here, the image data is data representing an image obtained by photographing an object. An object is an object that exists in space with a specific shape, and is an object that can distinguish objects independently such as an object and its surroundings, or an object and other objects in an image. .

  Specifically, examples of the object include various objects existing in the space with specific shapes such as a person, animals and plants, a vehicle, furniture, tableware, a building, and a work of art. The object may be movable or may be immovable. As a means of photographing objects, for example, a camera installed in a TV station studio, a camera brought to a relay site, a camera used for shooting a drama or a movie, a still camera or video camera owned by an individual, or a camera function Mobile phone with a mark.

  The actual dimension data is data representing an actual dimension (actual dimension) in the actual space of the object. The actual dimension data is data representing the actual dimension in the actual space of the object in the image data, not the maximum dimension that the object can take (for example, height if the object is human). The actual size data includes not only data representing the actual size (physical size) of the object in the actual space, but also display magnification data and data indicating the display center position, etc., necessary for actual size display. Contains.

  The actual dimension data may be configured to include, for example, not only data directly representing the actual dimension of the object but also an actual dimension ratio between the objects. That is, when there are a plurality of objects in the image data, if the actual dimensions of any one object are known using the above-described method, the actual dimensions of the plurality of objects may be represented by the ratio of the actual dimensions between the objects. it can.

  The actual dimension data may include, for example, data representing a ratio of an actual dimension of an object to a reference object (hereinafter referred to as “reference object”) existing on the screen. Here, if the actual size of the reference object is known, the actual size of the object is not limited to data that directly represents the actual size of the object, but can be expressed by the ratio of the actual size of the reference object to the actual size of the object. . When the reference object does not exist in the image represented by the image data, that is, when the image is an image of only the object, the actual size data depends on the ratio between the actual size of the finder frame including the object in the plane and the actual size of the object. It can be shown.

  Here, the finder frame usually represents an outline of a range that can be photographed by the photographing means when photographing an object existing at a predetermined distance from the photographing means. The viewfinder frame becomes larger as a wider-angle lens is used for photographing by the photographing means. Hereinafter, the finder frame having the above-described concept is referred to as “normal finder frame”. The photographing means has an object in the finder frame that exists in a virtual cone-shaped space that expands toward the normal finder frame from the focal point where the reflected light from the object is imaged by the photographing means. Shoot as an object.

  By the way, when a plurality of planes parallel to the plane framed by the normal finder frame are assumed between the above-mentioned focal position and the normal finder frame, each finder frame representing the outline of each plane is the normal finder. The closer the focus position is, the smaller the size is while maintaining a similar relationship with the frame shape.

  An object photographed by the photographing means is included in a plane formed by a finder frame representing the outline of any one of the plurality of finder frames. That is, the actual size of the object can be expressed by the ratio of the actual size of the object to the actual size of the finder frame if the actual size of the finder frame including the object in the plane is known.

  In the image data, when there are a plurality of objects, there are a plurality of finder frames that include the object in the plane. Here, if the actual dimensions of the finder frame including any one object in the plane among the plurality of finder frames including the object in the plane are known, the remaining size is determined by the ratio of the actual dimension to the actual dimension of the finder frame. The actual dimensions of the viewfinder frame can be shown.

  The actual size data is not limited to one associated with image data representing one object. For example, the image data representing one object may include a plurality of actual dimension data associated with each part of the object. Specifically, for example, if the image data represents an object whose distance to the imaging means varies depending on the part, the actual dimension data of the predetermined part of the object and the predetermined part represented by the actual dimension Actual dimension data of any part other than the predetermined part may be associated for each predetermined part.

  Here, as a specific example, image data obtained by photographing a passenger car from diagonally forward will be described as an example. For example, when the headlight of a passenger car is a predetermined part, the actual dimension data of the rear wheel portion at an arbitrary position is a numerical value smaller than the actual dimension value of the rear wheel. On the other hand, even if the image data is the same, if the rear wheel portion of the passenger car is a predetermined part, the actual dimension data of the headlight that is an arbitrary part is larger than the actual dimension value of the headlight.

  That is, when it is assumed that there are a plurality of frame surfaces parallel to the finder frame of the photographing means in the approaching / separating direction with respect to the photographing means, all the actual dimensions that represent the actual dimensions as long as the parts are located on the same frame surface. Although it is data, other part actual dimension data is larger than the actual dimension depending on whether or not the part located on a different frame surface is closer to the imaging means with respect to the frame where the predetermined part is located A numerical value or a small numerical value.

  The actual dimension data may be input through an input operation by an image data creation person such as an image photographer, or the distance from the photographing position by the photographing means to the object or each part and the height that can be photographed by the photographing means. It may be calculated as appropriate using the length. The content distribution device 110 may distribute the content at a predetermined timing such as a broadcast time assigned to each content, or may distribute the content at an arbitrary timing on the Internet.

(Functional configuration of display device 120)
Next, a functional configuration of the display device 120 will be described with reference to FIG. The display device 120 includes a display unit 121, a reception unit 122, a reception unit 123, and a display control unit 124. The display unit 121 has a display screen for displaying an image. The receiving unit 122 receives content including image data and actual size data of an object in the image data. Specifically, the receiving unit 122 receives content transmitted directly from an external device such as the content distribution device 110 described above or indirectly through a server or the like. The receiving unit 122 may be configured to extract image data stored in a large-capacity memory (not shown) in the display device 120, not only from an external device.

  The accepting unit 123 accepts designation of an object in the image data included in the content received by the receiving unit 122. For example, based on the image data included in the content received by the receiving unit 122, a normal-size image is displayed on the display screen of the display unit 121, and an object is specified by selecting an arbitrary object from the normal-size image. Can be accepted. Here, the equal-size image is an image in which image data included in the content received by the receiving unit 122 is displayed on the display screen without adjusting the display magnification for the image data.

  Specifically, the specification of the object in the reception unit 123 can be performed using, for example, a touch panel stacked on a display screen, a remote control key including a cursor, or the like. Note that the equal-size image refers to an image displayed as it is based on the image data without performing display magnification adjustment processing such as enlargement or reduction on the image data included in the content received by the receiving unit 122. It is.

  The accepting unit 123 may accept designation of a predetermined part on the designated object in addition to designation of the object. The part that receives the designation may be designated in the content distribution apparatus 110 that is the transmission source of the image data, or may be any part designated by the viewer.

  In addition, the display control unit 124 is based on the actual dimension data of an object (hereinafter referred to as “designated object”) whose designation is received by the receiving unit 123 among the actual dimension data included in the content received by the receiving unit 122. Then, an image in which the display magnification is adjusted so that the designated object becomes an actual size on the display screen of the display unit 121 is displayed.

  The display control unit 124 uses the actual size data included in the content received by the receiving unit 122 and the size data of the display screen to adjust the display magnification according to the size of each display screen, thereby specifying the designated object. Is displayed on the display screen of the display unit 121 so as to be an actual size. Note that the display control unit 124 receives information related to the size of the display screen of the display unit 121 set by the user (set via the receiving unit 123) or screen size data from the display unit 121, and the like. The size information of the display screen 121 may be acquired.

  For example, when the actual size of the entire designated object is larger than the size of the display screen, the display control unit 124 performs a predetermined image process on the image data for a part of the designated object in the image data to display the display screen. To display the actual size. In this case, the portion that could not be displayed on the display screen is cut. At the time of display, the display control unit 124 may display the designated object at the center of the display screen. In addition, when designation of a predetermined part is received by the receiving unit 123, control may be performed so that the predetermined part is displayed around the center of the display screen.

  For example, when the actual size of the finder frame is smaller than the size of the display screen of the display unit 121, the display control unit 124 may perform control so that the finder frame is displayed at the center of the display screen. In this case, the display control unit 124 combines the original image data with a wallpaper image and additional information (for example, an image based on additional information such as a news headline and a weather forecast, and a CM (commercial message image)). You may control to display the arbitrary image data mentioned above in the gap produced by the size difference between the image represented by the original image data and the display screen.

  Then, it is determined whether or not the designation of the object has been accepted by the accepting unit 123 within a predetermined time after displaying the same size image (step S203), and if not accepted (step S203: No), a series of The process ends. Here, if the same-size image displayed in step S202 is a moving image, for example, after displaying the same-size image of a certain scene, the same-size image of the next scene is displayed. Can be set up to On the other hand, if the same size image displayed in step S202 is a still image, it may be an arbitrary time set in advance by the viewer such as “1 minute” or “30 seconds”.

  In step S203, if the object designation is accepted by the accepting unit 123 within a predetermined time after displaying the same size image (step S203: Yes), the content received by the receiving unit 122 in step S201: Yes. Among the actual dimension data included in the image, the display control unit 124 adjusts the display magnification so that the designated object whose designation is accepted by the accepting unit 123 becomes the actual size on the display screen of the display unit 121 (magnified image) ) Are displayed (step S204), and the series of processes is terminated.

As shown in FIG. 8, the picture data is associated with data 800 that is a set of profiles 801 and 802 in which the actual dimension data and part data of the object in the image represented by the picture data are described.

  For example, in the profile 801 that is a part of the actual size data 800, the size data represents the physical length of the object 701 in the vertical direction of the display 513. Here, the size data represents the physical length of the person A in a certain picture in the vertical direction, not the height of the person A as the object 801.

  Data 800 is provided for each piece of picture data, and the contents of profiles 801 and 802 that are actual size data differ for each piece of picture data, even for profiles relating to one object 701. Also, the number of profiles differs for each picture data according to the number N of objects in the picture data. Specifically, for example, it may be changed for each frame of a video (a still image every 1/30 seconds in the NTSC system), or GOP (Group) which is a minimum unit structure constituting a moving picture such as MPEG2. It may be changed for each of (Of Pictures).

  Each object is assigned an object number from 1 to n for each picture data. In each picture data, the maximum value of the object number n is N. Each part in each object is assigned a part number of 1 to m. In each object, the maximum value of the part data is M.

  The site data in each of the profiles 801 and 802 represents the site to be displayed at the center of the display 513 as coordinates for the entire image. As described above, the number M of the part data is set to one or a plurality for each object. In the profiles 801 and 802, the height of each finder frame (sub-finder frame) including the object may be described. The height of the finder frame (sub-finder frame) will be described later.

  Profiles 801 and 802 are provided for each of the objects 701 and 702 (the profile 801 is for the object 701 and the profile 802 is for the object 702). On the data, when the cursor key 601 or 602 for object selection is operated, the profiles 801 and 802 to be selected are sequentially switched. The CPU 501 described above controls the video I / F 512 according to the profile 801 or 802 to be selected. Then, by operating the cursor key 703 or 704 for object selection, the part data in the profile 801 or 802 is sequentially switched.

  Further, the above-described size data may be highlighted on the display 513 in the form of numerical values by a predetermined operation on the input device 514. In this case, specifically, for example, a numerical value representing the physical data (length, mass, etc.) of the object displayed in actual size on the display 513 is displayed on the display 513.

In FIG. 9, the function regarding the transmission of content is demonstrated among the various functions with which the server 310 is provided. As illustrated in FIG. 9, the server 310 includes encoding units 901 to 903, an optimization unit 904, a packetization / multiplexing unit 905, a modulation unit 906, and a transmission unit 907.

Here, the audio signal is an electric signal generated based on the audio data related to the above-described image data. The encoding unit 903 encodes the data signal. Here, the data signal is an electric signal generated based on code data that is data other than image data and audio data among data transmitted from a broadcasting station or the like in digital broadcasting.

  The optimization unit 904 optimizes the actual dimension data described above. When user data other than actual dimension data is input, the optimization unit 904 optimizes the actual dimension data and the user data together. The encoding unit 901 described above encodes various data and video signals optimized by the optimization unit 904.

  The packetizing / multiplexing unit 905 packetizes various signals encoded by the encoding units 901 to 1003 and generates multiplexed content. The modulation unit 906 performs orthogonal frequency division multiplexing (ODFM) on the content generated by the packetization / multiplexing unit 905. The ODFM is a kind of digital modulation method, and performs modulation for transmitting the content generated by the packetizing / multiplexing unit 905 using a large number of carrier waves. The transmission unit 907 outputs the content modulated by the modulation unit 906 to the display device 320 via a network such as the Internet.

  Here, the structure of data encoded by the encoding unit 903 will be described. FIG. 10 is an explanatory diagram showing a data structure. FIG. 10 shows the structure of data encoded by the encoding unit 903. As shown in FIG. 10, the data 1000 encoded by the encoding unit 903 includes “sequence header” data 1001, “sequence extension” data 1002, “extension & user” data 1003, “group picture header” data 1004, User data "data 1005," picture header "data 1006," picture coding extension "data 1007," extension & user "data 1008," picture data "data 1009, and" sequence end "data 1010. .

  The various data 1001 to 1010 are well-known techniques as represented by the technical field of terrestrial digital broadcasting, and the description thereof is omitted. However, the actual size data (see FIG. 8) described above is “user data”. ] Is described as a part of the data 1005.

(Functional configuration of display device 320)
Next, a functional configuration of the display device 320 will be described. FIG. 11 is a block diagram showing a functional configuration of the display device 320. In FIG. 11, a display device 320 includes a receiving unit 1101, a demodulating unit 1102, a demultiplexing processing unit 1103, an audio decoding unit 1104, an audio memory unit 1105, a video decoding unit 1106, a video memory unit 1107, The encoding / decoding unit 1108, the actual size data detection unit 1109, the actual size memory unit 1110, the data memory unit 1111, the display magnification calculation unit 1112, the size memory unit 1113, and the output unit 1114 are provided.

  First, the receiving unit 1101 receives content transmitted from the server 310. The demodulation unit 1102 demodulates the content received by the reception unit 1101 using the same method as the modulation in the modulation unit 906 described above. The demultiplexing processing unit 1103 separates the content demodulated by the demodulating unit 1102 into a video signal, an audio signal, and other signals.

  Also, the audio decoding unit 1104 decodes the audio signal separated by the demultiplexing processing unit 1103 to generate audio data. The voice memory unit 1105 stores the voice data generated by the voice decoding unit 1104. The video decoding unit 1106 decodes the video signal separated by the demultiplexing processing unit 1103 and generates image data. The video memory unit 1107 stores the image data generated by the video decoding unit 120.

  Also, the code decoding unit 1108 decodes signals other than the video signal and the audio signal among the signals separated by the demultiplexing processing unit 1103. The actual dimension data detection unit 1109 detects actual dimension data from the data generated by decoding the signal by the code decoding unit 1108. In addition, the actual dimension data detection unit 1109 uses the dimension H (Hs) in the height direction of each finder frame (sub-finder frame) that includes the object in the plane from the data generated by decoding the signal by the encoding / decoding unit 1108. Or, coordinates represented by each part data are detected.

  The actual dimension memory unit 1110 stores actual dimension data detected by the actual dimension data detection unit 1109 and the height direction dimension H (Hs) of the finder frame (sub-finder frame). The data memory unit 1111 stores data other than the actual size data, such as code data, among the data generated by decoding the signal by the code decoding unit 1108.

  The display magnification calculator 1112 displays the image data display magnification in order to display the objects 701 and 702 selected by the operation of the actual size display switch 600 in the input device 514 among the objects in the image data on the display 513. The display magnification for adjusting is calculated.

  When calculating the display magnification, the display magnification calculation unit 1112 uses the actual size data stored in the actual size memory unit 1110, the image data stored in the video memory unit 1107, and the size data of the display 513. The size data of the display 513 is stored, for example, in a size memory unit 1113 provided in the ROM 502 or the like.

  The output unit 1114 outputs the audio data stored in the audio memory unit 1105, the image data stored in the video memory unit 1107, and the code data stored in the data memory unit 1111 while adjusting the respective timings. Specifically, for example, the CPU 501 controls the audio I / F 509 and the video I / F 512 to output audio from the speaker 511 and display images and character information on the display 513.

(Processing procedure of server 310)
Next, the processing procedure of the server 310 will be described. FIG. 12 is a flowchart showing the processing procedure of the server 310. In the flowchart of FIG. 12, first, various data necessary for content generation is acquired (step S1201), and encoding is performed using the acquired data (step S1202).

  Then, the data encoded in step S1202 is packetized and then multiplexed (step S1203). The multiplexed data is ODFM modulated (step S1204) and then transmitted (step S1205).

(Processing procedure of display device 320)
Next, a processing procedure of the display device 320 will be described. FIG. 13 is a flowchart showing the processing procedure of the display device 320. The process shown in FIG. 13 is executed when a certain piece of picture data is displayed on the display 513 based on the image data included in the content distributed from the server 310.

  In the flowchart of FIG. 13, first, it waits until the content distributed from the server 310 is received (step S1301: No). When the content is received (step S1301: Yes), the image data included in the received content is displayed. The same size image is displayed on the display 513 (step S1302). Then, it is determined whether designation of an object in the image displayed on the display 513 has been received within a predetermined time after displaying the equal-size image (step S1303). If the designation has not been accepted (step S1303: No), the series of processing ends.

  In step S1303, when designation of an object is received within a predetermined time after displaying the same-size image (step S1303: Yes), the designated object (hereinafter referred to as “designated object”) is in-plane. The display magnification is calculated using the actual size data of the finder frame included in the image and the size data of the display 513 (step S1304), and the scaled image obtained by scaling the image displayed in step S1302 according to the calculated display magnification is obtained. The information is displayed on the display 513 (step S1305), and the series of processing is terminated.

  Next, the relationship between the focal length of the lens and the angle of view in the imaging unit will be described. FIG. 14 is an explanatory diagram showing the relationship between the focal length of the lens and the angle of view. FIG. 14 shows the angle of view in the vertical direction when an object existing at a predetermined distance in the horizontal direction from the imaging means is imaged. As shown in FIG. 14, when the dimension in the height direction on the imaging surface of an object photographed using a lens with a focal length F is X, the focal length F and the dimension X and the angle of view θ of the lens The relationship is expressed by the following equation (1). Note that reference numeral 1402 in FIG. 15 represents the focal position of the lens.

tan (θ / 2) = (X / 2) / F
= X / (2F) (1)

  Accordingly, from the equation (1), the angle of view θ is expressed by the following equation (2).

θ = 2 · arctan (X / (2F)) [rad]
= (180 / π) × 2 · arctan (X / (2F)) [deg] (2)

  Next, the relationship between the dimensions of the range (finder frame) that can be photographed by the photographing means and the actual dimensions in real space will be described. FIG. 15 is an explanatory diagram illustrating an example of an image, and FIG. 16 is an explanatory diagram illustrating dimensions of the finder frame. In FIGS. 15 and 16, an imaging means (photographer) existing at a certain position uses the lens having the angle of view θ described above to photograph an object that is a distance L in the horizontal direction from the focal position of the lens. In this case, the relationship between the dimension in the height direction that can be photographed by the photographing means and the dimension in the actual height direction in the real space is shown.

  When the distance in the horizontal direction from the focal position of the lens to the object is L, the dimension H in the height direction of the finder frame 1501 shown in FIG. 15 is expressed by the following equation (3). Note that reference numeral 1502 in FIG. 15 represents an object in the finder frame 1501.

H = 2L · tan (θ / 2)
= 2L · tan ((180 / π) × 2 · arctan (X / (2F)) / 2)
... (3)

  If the dimension X, the distance L, and the focal length F are known from the expression (3), the dimension H in the height direction of the finder frame 1601 can be obtained. The dimension X can be obtained in advance by placing a reference object whose dimension (length) is already known in the finder frame where the target exists, and the distance L is obtained by actually measuring the distance L using various measuring means. be able to. The focal length F is also known from the camera lens specifications. Therefore, the dimension H in the height direction of the finder frame 1601 can be obtained in real time while photographing.

  Also, it can be seen from the expression (3) that the dimension H in the height direction of the finder frame 1501 depends on the focal length F of the lens and the distance L in the horizontal direction from the focal position of the lens to the object to be photographed. For this reason, for example, even if an image of a subject is captured using the zoom function, if the focal length F of the lens is known, the height of the finder frame 1501 can be increased regardless of the lens having any focal length F. The vertical dimension H can be calculated.

  By the way, the object existing in the finder frame 1501 is in a conical virtual space that expands from the focal position of the lens toward the finder frame 1501 between the focal position of the lens and the target in real space. It is an existing object. Here, FIG. 17 is an explanatory diagram for explaining the size of the sub-finder frame.

  As shown in FIG. 17, the sub-finder frame is defined by the above-mentioned cone-shaped virtual space among a plurality of planes parallel to the focal point 1701 of the lens and the plane framed by the above-described finder frame 1501. It represents the area that can be viewed. The sub-finder frames 1703 and 1704 shown in FIG. 17 are smaller in size as they are closer to the focal position 1701 of the lens while maintaining a similar relationship with the shape of the finder frame 1501.

  In FIG. 17, the dimension H2 in the height direction of the sub-finder frame 1704 close to the focal position 1701 of the lens is smaller than the dimension H1 in the height direction of the sub-finder frame 1703. For example, when the actual dimension data of the objects 1 and 2 is represented by the ratio of the actual dimension of the object to the actual dimensions of the sub-finder frames 1703 and 1704, respectively, Each data is different.

  Next, a display magnification calculation method will be described. The display magnification depends on the size relationship between the actual dimension Hs of the sub-finder frame including the object to be selected in the plane and the dimension Hd of the display 513, and “Hs> Hd”, “Hs = Hd”, “Hs < Hd ”is divided into three patterns. Here, the actual dimension Hs of the sub-finder frame and the dimension Hd of the display 513 are the dimensions in the vertical direction. The display method program described below is stored in the ROM 502 and executed by the CPU 501.

  First, the case where the first pattern is “Hs> Hd” will be described. FIG. 18 is an explanatory diagram (part 1) illustrating a method for calculating the display magnification. 18 shows the magnitude relationship between the actual dimension H2 in the height direction of the sub-finder frame 1704 including the object 2 (indicated by reference numeral 1801) in FIG. 17 in the plane and the dimension Hd of the display 513.

  As shown in FIG. 18, when picture data relating to the sub-finder frame 1704 is displayed on the display 513 without being processed (at the same magnification), the actual dimension H2 of the object 2 is displayed on the display 513 like a general television receiver. A display screen 1803 including an object 1802 reduced at a ratio of Hd / Hs = Hd / H2 is displayed. Therefore, when “Hs> Hd”, Hs / Hd, which is the inverse ratio of the reduction ratio, is calculated as the display magnification. As a result, the selected object 1801 can be enlarged and an image with the display magnification adjusted so as to be the actual size on the display 513 can be displayed.

  By the way, when “Hs> Hd”, a part of the object may protrude from the display 513 by enlarging the object 1801. Specifically, for example, when the object located at the end of the image displayed at the same magnification is enlarged to display the actual size, but is enlarged around the center of the image displayed at the same magnification. It is assumed that the target object 1801 is not displayed on the display 513.

  In such a case, the above-described actual size display switch 600 can be operated to display a desired part of a desired object at the center of the display 513. Here, FIG. 19 is an explanatory diagram (part 1) for explaining the adjustment of the display magnification. FIG. 19 shows a display screen 1803 in which picture data is displayed at the same magnification on the display 513 and a display screen 1903 in which an object 1902 is displayed in an enlarged manner.

  As shown in FIG. 19, by specifying an enlargement center point 1901 on the display screen 1803 on which picture data is displayed at the same magnification, as shown on the display screen 1903, the specified object 1902 or a specific part in the object 1902 is displayed. Can be reliably displayed on the display 513. Of course, in the actual size display mode, it may be set as default in the display control unit so that the display position coordinate of the first part described in the actual size data is displayed as the center of the screen as a default. .

  Next, the case where “Hs = Hd”, which is the second pattern, will be described. Although illustration is omitted, in this case, the picture data related to the sub-finder frame 1704 is displayed on the display 513 at the same magnification (without performing special image processing), so that the selected object 1801 is the actual size on the display 513. The image which becomes can be displayed.

  Next, a case where the third pattern is “Hs <Hd” will be described. FIG. 20 is an explanatory diagram (part 2) illustrating a method for calculating the display magnification. FIG. 20 shows the magnitude relationship between the actual dimension H2 in the height direction of the sub-finder frame 1704 including the object 2 (indicated by reference numeral 1801) in FIG. 18 in the plane and the dimension Hd of the display 513.

As shown in FIG. 20, when the picture data related to the sub-finder frame 1704 is displayed on the display 513 at the same magnification, the display 513 displays Hd / Hs = Hd / H2 with respect to the dimension H2 of the sub-finder frame 1704 in the height direction. The display screen 2003 including the object 2002 enlarged at the ratio, that is, the object 2002 enlarged from the actual size in the real space is displayed.

Therefore, when “Hs <Hd”, Hs / Hd , which is the inverse ratio of the enlargement ratio, is calculated as the display magnification. FIG. 21 is an explanatory diagram (part 2) for explaining the adjustment of the display magnification. As shown in FIG. 21, by using the calculated display magnification Hs / Hd , a display screen 2103 including an object 2102 in which the display magnification is adjusted to be an actual size by reducing the enlarged object 2002 is displayed. Can be displayed.

  By the way, when “Hs <Hd”, the size of the entire image becomes smaller than the size of the display 513 by reducing the image displayed at the same magnification. In such a case, as shown in FIG. 21, the original image is displayed at the center of the display 513, and a preset wallpaper 2101 is displayed as the difference between the size of the display 513 and the size of the original image.

  The pattern of the wallpaper 2101 may be set uniquely when the display device 320 is manufactured, or the viewer can select arbitrary wallpaper data by operating the actual size display switch 600 described above. Also good. Further, the display position of the image on the display screen 2103 is not limited to the center portion of the display 513, and for example, the lower end of the image and the lower end of the display 513 may be displayed together.

  In addition, the additional image is not based on the wallpaper 2101 but based on information such as a headline about received news, a weather forecast, a CM (commercial message), a state of home appliances connected via a network (ON / OFF, etc.), and the like. May be displayed on the display 513. On the display 513, the additional image may be displayed instead of the wallpaper 2101 or superimposed on the wallpaper 2101. The additional image data for displaying the additional image on the display 513 may be generated by the display device 320, or information received from an external device may be used.

  The actual dimensions are not limited to those represented by the ratio of the object dimensions to the height dimension H of the finder frame 1501 (or the height dimensions Hs = H1, H2 of the sub-finder frames 1703 and 1704). . For example, you may acquire the actual dimension of imaging | photography object by a measurement. The actual dimension can be measured relatively easily using, for example, the method described below.

  FIG. 22 is an explanatory diagram for explaining a method for measuring an actual size of an imaging target. With reference to FIG. 22, a method for measuring the actual dimension of the subject in the vertical (height) direction will be described. As described above, since the focal length F of the lens in the photographing means is known at the time of photographing, both the end portions in the height direction of the photographing object centering on the distance L from the focal position 1701 of the lens to the photographing target and the focal position 1701 of the lens. If the opening angle up to is known, the actual dimension H (R) of the object to be imaged can be measured.

  Specifically, for example, when the target 2 in FIG. 22 is a measurement target, the distance L from the focal position 1701 of the lens to the target 2 can be measured semi-automatically using a known LED survey technique. . In addition, an elevation angle θ1 from the focal position 1701 of the lens to the upper end portion (the top of the head) in the height direction of the object 2 and a depression angle θ2 from the focal position 1701 of the lens to the lower end portion (toes) of the height direction in the object 2 are It can be automatically surveyed using known techniques.

  When the actual dimension data of the object is acquired by measurement, the dimension of the finder frame (or sub-finder frame) can be calculated using the method described below. Here, FIG. 23 is an explanatory diagram for explaining a method of calculating the dimension of the finder frame (or sub-finder frame).

  In FIG. 23, the calculation method of the dimension H in the height direction of the finder frame 1501 (or the dimension Hs = H1, H2 in the height direction of the sub-finder frames 1703 and 1704) will be specifically described. When this method is used, specifically, for example, the size H (P) of the pixels arranged in the display 513 in the height direction and the number N of arrangement in the height direction are stored in the size memory unit 1113 in advance. Remember.

  In this case, first, in the image displayed on the display 513 at the same magnification, the number No. of pixels used for displaying the object in the height direction is acquired. The number No is expressed by the following equation (4).

    No = H (R) / H (P) (4)

  Next, using the ratio between the number N of pixels arranged in the display 513 in the height direction and the number No calculated by the equation (4), the height dimension H (of the finder frame 1501) Alternatively, the dimension Hs) in the height direction of the sub-finder frame 1704 is calculated. The dimension H (or dimension Hs) is expressed by the following equation (5).

    H (or Hs) = (N / No) × H (R) (5)

  When the dimension H in the height direction of the finder frame 1501 (or the dimension Hs in the height direction of the sub-finder frame 1704) is calculated using such a method, the selection is made in the same manner as described above. It is possible to display an image in which the display magnification is adjusted so that the displayed object becomes an actual size on the display 513.

  Next, a processing procedure of the display device 320 will be described. 24 to 31 are flowcharts showing the processing procedures (No. 1) to (No. 8) of the display device 320. First, the processing procedure (part 1) of the display device 320 will be described with reference to FIG. The processing procedure shown in FIG. 24 is performed prior to image display. In the flowchart shown in FIG. 24, first, the power is turned on (step S2401: No). When the power is turned on (step S2401: Yes), it is determined whether or not the setting switch described above has been operated. (Step S2402).

  In step S2402, when the setting switch is operated (step S2402: Yes), a display size request message is output (step S2403). Here, the display size request message is a message requesting the user to input the size of the display 513 (the dimension Hd of the display 513). Specifically, in step S2403, for example, a message such as “Please input the display size” is displayed on the display 513, or is output as sound from the speaker 511.

  Then, in response to the display size request message output in step S2403, the process waits until the size data of the display 513 is input (step S2414: No), and if it is input (step S2404: Yes), The input size data is stored in the size memory unit 1113 (step S2405).

  Thereafter, the input device 514 waits until a setting completion operation is accepted (step S2406: No). If accepted (step S2406: Yes), an image is displayed on the display 513 (step S2407), and a series of processes is performed. Exit. In step S2402, when the setting switch is not operated (step S2402: No), other processes are appropriately executed (step S2408), and the series of processes is terminated. In step S2407, specifically, for example, a process of displaying an image on the display 513 is performed.
