Description

The present invention relates to a camera photographing support system that supports a photographing method when a camera user photographs a subject such as a building or a landscape with a camera having a position information detection unit.

  When an amateur user who is not a professional photographer takes a picture of a camera, what is most difficult is the composition of the subject and the position from which the subject should be taken. Therefore, Patent Documents 1 to 3 listed below disclose an invention that gives advice on a composition that is generally referred to as a bad composition, which is called a defective composition.

  Patent Document 4 below discloses an invention in which, after a user of a camera takes a picture, the user's tendency is analyzed by analyzing the shooting state of the picture to give advice on the shooting method.

  Further, Patent Literature 5 and Patent Literature 6 below disclose an invention in which a user gives advice and makes settings so that photographing can be performed under appropriate photographing conditions.

JP-A-6-337467 JP 2000-333045 A JP 2003-338955 A JP 2004-112054 A JP 2004-80205 A JP 2002-10133 A JP-A-8-184436

In this regard, Japanese Patent Laid-Open No. 2001-257920 and Japanese Patent Laid-Open No. 2005-333628 disclose a method of automatically photographing a subject by detecting the position of the camera, but the photographing is automated. Therefore, it may be effective under special circumstances such as shooting from a moving vehicle or aerial shooting from a helicopter, but it is not suitable for general users to perform camera shooting.

  In addition, since the invention of Patent Document 4 needs to analyze a photograph (image data) taken by the user, at least some photographs must be taken in advance. For this reason, for example, when photographing a subject of a tourist attraction, etc., it is practically impossible to take several photos and analyze them for advice.

  Furthermore, although it is possible to receive advice on the shooting environment by using the inventions of Patent Document 5 and Patent Document 6, it is a problem described above, whether the camera should be held vertically or if it is taken horizontally.

  An overall conceptual diagram of the camera photographing support system 1 of the present invention is shown in FIG. An example of the system configuration is shown in the conceptual diagram of FIG.

  A camera photographing support system 1 according to the present invention includes a camera 2 and a subject information providing server 3. A conceptual diagram of a hardware configuration of the subject information providing server 3 is schematically shown in FIG. This server has at least an arithmetic unit 20 such as a CPU for executing arithmetic processing of a program, and a storage unit 21 such as a RAM and a hard disk for storing information. Each function (each unit) realized on the computer is executed when a unit (program, module, etc.) for executing the process is read into the arithmetic unit 20. When each function uses the information stored in the storage unit 21 in the process, each function reads the corresponding information from the storage unit 21 and uses the read information for the process in the arithmetic unit 20 as appropriate. The computer includes a communication device 24 that transmits and receives processing results of the arithmetic device 20 and information stored in the storage unit 21 via a network such as the Internet or a LAN, an input device 23 such as a keyboard, a mouse, or a numeric keypad, and a display such as a display. The device 22 may be included.

  Each means in the present invention is only logically distinguished in function, and may be physically or practically the same area.

  The subject information providing server 3 stores information on the width and height of buildings and landscapes (such as mountains) (collectively referred to as subjects) together with the position information, and is based on an inquiry from the camera 2. Information on the width and height of the subject. For example, when Roppongi Hills is selected as the subject, the subject information providing server 3 receives information from the camera 2 that Roppongi Hills has been selected as the subject and an acquisition request for its height, width, and position information. Based on this acquisition request, the subject information providing server 3 searches for information on various stored subjects, extracts the height, width, and position information of Roppongi Hills and passes them to the camera 2.

  The camera 2 includes a position information detection unit 4, a subject information acquisition unit 5, a distance calculation unit 6, an orientation detection unit 7, a photographing advice processing unit 8, and a notification unit 9.

  The position information detection unit 4 detects the position information of the camera 2 by GPS or the like. In addition to the GPS, the position information may be a method of detecting a position based on a position where an IC tag or the like is read.

  The subject information acquisition unit 5 acquires information about the subject that the user has taken as an object, such as information on the width and height of the subject, position information, and the like from the subject information providing server 3 via a network such as the Internet.

  The distance calculation unit 6 calculates the distance between the camera 2 and the subject based on the position information of the camera 2 detected by the position information detection unit 4 and the position information of the subject acquired from the subject information providing server 3.

  The direction detection unit 7 detects which direction the lens of the camera 2 is facing, based on a direction magnetic needle (including an electronic compass) provided in the camera 2.

  The shooting advice processing unit 8 is based on the distance from the camera 2 to the subject calculated by the distance calculation unit 6 and the information on the width and height of the subject acquired by the subject information acquisition unit 5. When the user shoots a subject with the camera 2, processing for advice on the shooting method is performed. Further, based on the direction information detected by the direction detection unit 7, it is determined which direction the lens of the camera 2 should be directed. The advice on the shooting method includes whether the camera should be held vertically, whether it should be held horizontally, from which position it should be taken, and at what magnification should be taken.

  The notification unit 9 notifies the user of advice corresponding to the result determined by the shooting advice processing unit 8. For example, an instruction based on the determination is displayed on a display device 22 provided in the camera 2 or output by an audio output device. With these outputs, the user can receive advice from the camera 2. As for the advice corresponding to the determination result, the determination result and the content of the advice are stored in association with each other, and the advice corresponding to the determination result is extracted based on the determination result.

  Next, an example of the processing process of the camera photographing support system 1 of the present invention will be described with reference to the flowchart of FIG. 4 and the conceptual diagram of FIG.

  First, a user using the camera photographing support system 1 of the present invention selects a subject to be photographed by performing a predetermined operation on the camera 2. For example, by using the input device 23 (button or the like) provided in the camera 2, the camera 2 accepts the selection of the subject by inputting characters or selecting a name from the map (S100).

  When the subject is selected in this way, the position information detection unit 4 detects information on the current position of the camera 2 (S110). The position information of the camera 2 may be periodically performed or may be performed before the subject is selected in S100.

  Based on the information selected in S100, the subject information acquisition unit 5 communicates with the subject information providing server 3 to acquire information about the subject, for example, information on the width and height of the subject, and position information on the subject. The request is passed to the subject information providing server 3. When the subject information providing server 3 receives this acquisition request, information relating to the subject stored in advance, for example, subject width and height information and subject position information is extracted and passed to the camera 2.

  The camera 2 receives from the subject information providing server 3 information related to the subject, such as information on the width and height of the subject, and position information on the subject (S120). The distance calculation unit 6 calculates the distance between the camera 2 and the subject based on the position information of the camera 2 detected by the position information detection unit 4 and the position information of the subject acquired by the subject information acquisition unit 5. (S130).

  Then, the direction detection unit 7 detects the direction in which the lens of the camera 2 is facing (S140). Further, the photographing advice processing unit 8 determines whether the subject is within the shootable range of the camera 2 based on the information on the distance between the camera 2 and the subject, the width of the subject, and the height, and is considered good for photographing. How to hold the camera 2 (whether the camera 2 is held horizontally or vertically), the direction in which the lens of the camera 2 is directed, how much the position should be moved, how much magnification should be used, etc. Advice on how to shoot a subject is determined (S150). At the time of this determination, information on the viewable angle of view corresponding to the lens mounted on the camera 2 and the viewable angle of view corresponding to each magnification when zoomed is stored in the camera 2 in advance. The angle of view is stored and information on this angle of view is used. FIG. 5 schematically shows information on the angle of view.

  FIG. 6 schematically shows the concept of calculating the shootable range of the camera 2. In FIG. 6, a case will be described in which it is determined whether the height of the subject is included in the shootable range R of the camera 2. The width of the subject can be calculated in the same manner.

First, since the information on the magnification (zoom) of the camera 2 is acquired, the vertical angle of view can be known, so that information is extracted. Then, based on the distance L from the camera 2 to the subject calculated by the distance calculation unit 6, the vertical shootable range is calculated by Equation 1.
(Equation 1)
R = (L × tan θ) × 2

  Then, the calculated shootable range R is compared with information on the height H of the subject acquired from the subject information providing server 3 by the subject information acquisition unit 5, and the shootable range R is larger than the information on the height of the subject. (When R> H), it can be determined that the vertical direction of the subject is included in the shootable range of the camera 2. On the other hand, when the shootable range R is smaller than the subject height information (when R <H), it can be determined that the vertical direction of the subject is not included in the shootable range of the camera 2. This case is schematically shown in FIG.

  As described above, based on the determination of the shootable range in the vertical direction and the determination of the shootable range in the horizontal direction, it is determined whether or not the subject is within the shootable range of the camera 2, and the camera 2 is set vertically and horizontally. It is determined which image should be taken (S150). FIG. 8 schematically shows an example of the correspondence relationship between the shootable range and advice notified to the user of the camera 2.

  In addition to determining whether the camera 2 should be taken vertically or horizontally, it is possible to determine whether the subject is in a predetermined size within the shootable range based on the calculated shootable range and information on the height or width of the subject. It is also possible to determine whether to zoom (or zoom out) or to use a magnification that changes the magnification to the predetermined size.

  Further, based on the calculated shootable range and the information on the height or width of the subject, the user moves forward, falls back, or moves forward so that the subject becomes a predetermined size of the shootable range. It may be determined that XX meters are at the back and XX meters down at the back.

  Note that the above-mentioned distance in front, the distance to fall back, and the magnification to be changed can be easily calculated from the angle of view and the photographic range.

  For example, when determining the distance, the shootable range R is calculated based on the size of the subject so that the size (height or width) of the subject becomes a predetermined size of the shootable range. For example, when the size of the subject is 50% of the shootable range, twice the size of the subject is set as the shootable range R. Then, the distance L to the subject is used as a variable (the angle of view θ and the shootable range R are already known at this time), and the distance L is calculated by the above-described formula 1. Then, the moving distance may be calculated by comparing the calculated distance L with the current distance between the camera 2 and the subject.

  The magnification can be calculated similarly. The shootable range R is calculated based on the size of the subject so that the size (height or width) of the subject becomes a predetermined size of the shootable range. For example, when the size of the subject is 50% of the shootable range, twice the size of the subject is set as the shootable range R. Then, instead of the distance L described above, the magnification, that is, the angle of view θ corresponding thereto is used as a variable (the distance L and the imageable range R are already known at this time), and the angle of view θ is calculated by the above-described equation (1). . Then, the magnification corresponding to the calculated angle of view θ is determined.

  After making such a determination, the notification unit 9 extracts the advice corresponding to the result determined by the photographing advice processing unit 8 and outputs it from the display device 22 of the camera 2, the audio output device, etc. (S160). For example, “Please hold camera 2 sideways”, “Please turn the lens of camera 2 to the north”, “Move forward XX meters”, “Please set the magnification to XX”, etc. Is output from the display device 22 or the audio output device. When the user views or listens to the notification for reference, the user can hold the camera 2 sideways, vertically, or how far forward or backward when photographing the subject. You can know exactly how much you should move and how much magnification you want.

  Further, the camera 2 may be automatically adjusted based on the result determined by the photographing advice processing unit 8 as described above. For example, when the notification unit 9 notifies that the magnification is XX times, the magnification of the camera 2 may be automatically adjusted to XX times.

In the first embodiment, the case where the camera 2 acquires the subject information from the subject information providing server 3 has been described. However, the subject information is stored in the storage unit 21 of the camera 2 or a recording medium readable by the camera 2. (The storage unit 21 and the recording medium are collectively referred to as “storage unit”). As a result, even if the camera 2 does not have a communication function, the same processing as in the first embodiment can be realized. In that case, the subject information acquisition unit 5 may not be provided in the camera 2.

By using the present invention, the user of the camera 2 can know whether the camera should be placed vertically, horizontally, or from which position the subject should be photographed, and the subject can be reliably photographed. It is possible not only to store, but also to perform appropriate shooting according to the subject.
