Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a communication system including a camera according to an embodiment of the present invention. The communication system shown in FIG. 1 includes a digital camera 100, which is an example of a camera according to an embodiment of the present invention, a server 300, a database 400, and a personal computer (PC) 500, which are in data communication with each other. It is configured to be freely connected.

  A digital camera 100 shown in FIG. 1 includes a microprocessing unit (MPU) 101, an operation unit 102, a photographing lens 103, an autofocus (AF) circuit 104, an aperture mechanism 105, an aperture control circuit 106, and an image sensor. 107, an analog front end (AFE) circuit 108, an image processing circuit 109, a display control circuit 110, a display panel 111, a text synthesis circuit 112, a distance detection circuit 113, a face detection circuit 114, a compression / The expansion unit 115 includes a recording control unit 116, a recording medium 117, a communication unit 118, and an auxiliary light emitting circuit 119.

  The MPU 101 sequentially controls each block constituting the digital camera 100 according to a predetermined program in accordance with the operation of the operation unit 102 from the user. The operation unit 102 displays a release switch for executing shooting by the digital camera 100, a changeover switch for switching to an operation mode shooting mode and a playback mode of the digital camera 100, and a sentence extracted from the literary book at the time of composition confirmation. A switch or the like for displaying on the panel 111 is included. In addition, when inputting a title to be described later from the digital camera 100, an operation unit for inputting characters is also included as the operation unit 102.

  The MPU 101 also has a timer for measuring the time when the user took a picture. Thereby, the photographing time is associated with the image data obtained by photographing.

  The taking lens 103 forms an image from the subject 200 on the image sensor 107. The photographing lens 103 includes a lens for autofocus (focusing). During autofocus, the MPU 101 controls the AF circuit 104 while switching the lens position of the focusing lens while monitoring the lens position of the focusing lens, and performs focusing of the photographing lens 103. In addition, when the photographing lens 103 includes a zoom lens, the angle of view at the time of photographing can be switched by switching the position of the zoom lens.

  The aperture mechanism 105 is a mechanism that is provided in the vicinity of the photographing lens 103 or has an effect of a shutter or an aperture. The aperture mechanism 105 is opened to a predetermined aperture by the aperture control circuit 106 at the start of shooting and closed at the end of shooting. By changing the aperture of the aperture mechanism 105 at the time of shooting, the depth of field of the shooting lens 103 changes. Thereby, it is possible to switch the expression such as adjusting the degree of blurring of the background subject to make the main subject appear at the time of shooting or to clearly depict the background subject.

  The image sensor 107 has a light receiving surface configured by arranging a large number of pixels, and converts an image from the subject 200 received through the photographing lens 103 into an electrical signal. In the present embodiment, the image sensor 107 may use either a CCD system or a CMOS system.

  The AFE circuit 108 includes a CDS circuit, a gain adjustment circuit, an AD conversion circuit, and the like, and is obtained by performing analog processing such as correlated double sampling processing and gain adjustment processing on the analog electric signal obtained in the image sensor 107. The obtained image signal is converted into digital data and input to the image processing circuit 109. The AFE circuit 108 is also provided with a function of reading signals from a plurality of pixels constituting the image sensor 107 at a time. For example, the AFE circuit 108 can read out signals of 4 pixels (2 × 2 pixels) and 9 pixels (3 × 3 pixels) in a lump and add these read-out electric signals to improve the S / N. . By such processing, the apparent sensitivity of the image sensor 107 can be increased.

  Further, the AFE circuit 108 also has a function of selecting an output signal from the image sensor 107, and can extract only signals from pixels in a limited range among all effective pixels of the image sensor 107. In general, the image sensor 107 can read signals at high speed by performing thinning. By using this function, a through image obtained for composition confirmation by the image sensor 107 is read at high speed, processed in the image processing circuit 109, and then displayed on the display panel 111. It is possible to perform framing using the image to be displayed.

  The image processing circuit 109 corrects the color, gradation, sharpness, etc. in the image data input from the AFE circuit 108, or amplifies the level of the image data to a predetermined level to adjust it to the correct shading and the correct gray level. Various image processing is performed.

  In addition, in order to display various images such as the framing through image as described above, the image processing circuit 109 resizes (reduces) the image data input from the AFE circuit 108 so that it can be displayed on the display panel 111. ).

  The display control circuit 110 converts the image data obtained by the image processing circuit 109 and the image data recorded on the recording medium 117 into a video signal, and displays it on the display panel 111. The display panel 111 as a display unit is a display panel such as a liquid crystal display panel or an organic EL display panel. The display control circuit 110 also has a multi-screen display function for displaying a plurality of images superimposed on the display panel 111. With this multi-screen display function, it is also possible to superimpose a character display of mode setting and various warning displays on the captured image or the captured image.

  The text synthesizing circuit 112 synthesizes the text data with the image data obtained by the image processing circuit 109 so that text of a passage such as a novel is displayed at a predetermined position on the screen. Details of this text composition will be described later.

  The distance detection circuit 113 detects the contrast of the image obtained by the image processing circuit 109. The contrast detected by the distance detection circuit 113 is used during autofocus. That is, while the AF circuit 104 changes the lens position of the focusing lens of the photographing lens 103, the distance detection circuit 113 sequentially detects the contrast of the image, and stops the focusing lens at the lens position where the detected contrast is maximized. By doing so, the photographing lens 103 can be focused.

  The face detection circuit 114 detects, in particular, the face of the main subject from the distribution of feature points in the image obtained by the image processing circuit 109 (for example, if the main subject is a person, eyes, nose, mouth, etc.).

  The compression / expansion unit 115 compresses the image data processed by the image processing circuit 109 at the time of shooting, and expands the image data read from the recording medium 117 via the recording control unit 116 at the time of reproduction.

  The recording control unit 116 records the image data compressed by the compression / expansion unit 115 on the recording medium 117 with accompanying data. The recording control unit 116 has a sentence database 116a as a recording unit for storing text used for text synthesis described later. The contents of the sentence database 116a may be recorded when the camera is manufactured, but can be rewritten via a network from the server 300 or the like outside the digital camera 100.

  The communication unit 118 performs communication control when transmitting image data or the like recorded on the recording medium 117 to the server 300 or the like outside the digital camera 100 or receiving various information from the server 300 or the like. The communication unit 118 can transfer an image captured by the digital camera 100 to another person, or can add information using a service on a network (for example, a service linked with a network-connected site). Can be received.

  The auxiliary light emitting circuit 119 irradiates the subject 200 with auxiliary light according to the situation at the time of shooting. This prevents insufficient brightness and unevenness during shooting. The operation of the auxiliary light emitting circuit 119 may be manually controlled by the user operating the operation unit 102.

  The server 300 is assumed to be a server that manages CGM (Consumer Generated Media) such as a blog or SNS (Social Networking Service). The server 300 includes a control unit 301, a communication unit 302, and a recording unit 303. The control unit 301 has a function of displaying the content recorded in the recording unit 303 on the PC 500 or the digital camera 100, a function of extracting text data of a predetermined sentence from the document data recorded in the document database 401 of the database 400, and the like. The various operations in the server 300 are controlled. The communication unit 302 performs communication control when the server 300 performs data communication with the digital camera 100, the database 400, and the PC 500. The recording unit 303 records various contents such as image data transmitted from the digital camera 100.

  The database 400 records various data referred to by the server 300. The database 400 includes a document database 401 and a subject database 402. The document database 401 records the title of a literary book and document data indicating the contents of the literary book in association with each other. The subject database 402 records, as text data, a keyword indicating the type, name, etc. of a subject for extracting a predetermined sentence from document data. This keyword includes information on the location of the shooting location, shooting time and time, season, and the like. In addition, specific proper nouns (for example, Mt. Fuji, the Sea of Japan, etc.), so-called Yamakawa Kuseki representing nature, phrases related to Hanafuru Fugetsu, haiku seasons and seasons, and the like are also included.

  The PC 500 is a computer in which software for browsing a web page is installed and has an operation unit such as a mouse and a keyboard and a display unit such as a liquid crystal display for performing various operations on the web page.

  In the communication system configured as described above, the title of a novel or essay (hereinafter referred to as a literary book) that the user has been impressed by is input to the server 300 via the PC 500, for example. Note that the title may be input via the digital camera 100. When a title is input, the control unit 301 of the server 300 reads out the document data of the title from the document database 401, examines every sentence included in the document data, and text data of the sentence according to a predetermined rule. And the text data of the extracted sentence is sent to the sentence database 116a of the digital camera 100 for recording. The predetermined rule when extracting sentence text data is whether or not the sentence includes a keyword recorded in the subject database 402, and the control unit 301 records the document data in the subject database 402. The text data of the sentence including the keyword that has been extracted is extracted.

  Hereinafter, extraction of sentence text data will be further described with reference to the schematic diagram of FIG. When the title of the literary book is input by the user, the document data of the title is retrieved from the document database 401. When the corresponding document data is retrieved from the document database 401, the control unit 301 collates the document data with the keywords recorded in the subject database 402. The subject database 402 includes images of nature (sky, mountain, river, sea, etc.), structures (buildings, shops, statues, etc.), animals and plants (flowers, trees, birds, etc.), equipment (clocks, desks, etc.), etc. The name of a subject that can be a subject at the time of shooting is recorded as a keyword. The control unit 301 extracts sentences including these keywords from the document data, and transmits the extracted sentence text data to the sentence database 116a of the digital camera 100 in the order in which they appear in the literary book. The MPU 101 of the digital camera 100 records the sentence data transmitted from the server 300 in the sentence database 116a in the order of transmission.

  Here, it is desirable to transmit the title of the literary book from the server 300 to the digital camera 100 together with the sentence data. Also, various information related to literary books such as author names may be transmitted together.

  The sentence data and the like recorded in the sentence database 116a of the digital camera 100 in this way are combined with the image data obtained at the time of shooting and recorded. For example, as shown in FIG. 3A, when a user operates a sentence display switch 102a provided in the digital camera 100 during framing before taking a picture, the sentence is recorded in the sentence database 116a together with a through image for composition confirmation. The text of the sentence is displayed. 3B and 3C show examples of sentence text display. FIG. 3B shows an example in which the through image 111 a for composition confirmation and the text 111 b of the sentence are displayed on different parts on the display panel 111. In addition, in FIG. 3B, in addition to the sentence text 111b, the text 111c of the title of the literary book that quotes the sentence is also displayed. On the other hand, FIG. 3C is an example in which the text 111b of the sentence and the text 111c of the literary book title are superimposed and displayed on the through image 111a for composition confirmation. Here, as shown in FIG. 3C, when the text is superimposed on the through image and displayed, it is preferable that the displayed text does not interfere with composition confirmation. This method will be described later.

  When the user performs a shooting operation in a state where an image as shown in FIG. 3B or 3C is displayed, the text data of the sentence and the text data of the title are combined with the image data obtained by shooting. And recorded on the recording medium 117.

  By such an operation, the user can take a picture with a balance between the text and the image. In addition, it is not necessary to quote text after shooting, and it is possible to enjoy shooting while confirming it at the time of shooting.

  Hereinafter, a flow of a content creation method using the communication system of FIG. 1 will be described with reference to FIGS. 4 and 5.

  FIG. 4 is a flowchart showing control on the server 300 side in the communication system of FIG. In FIG. 4, the control unit 301 of the server 300 determines whether or not the title of the literary book has been input by the user's operation on the PC 500 or the like (which may be an operation from the digital camera 100) (step S1). ). When the title of the literary book is input in the determination in step S <b> 1, the control unit 301 searches the document database 401 for document data corresponding to the title of the literary book, and searches the document data and the keyword data of the subject database 402. And a sentence including a keyword (for example, one sentence) is extracted (step S2). Then, the control unit 301 transmits the sentence text data and the title text data to the digital camera 100 in the extracted order (that is, the order in which the sentences appear in the document) (step S3). Thereafter, the control unit 301 ends the process of FIG. In this way, sentence text data and title text data are recorded in the sentence database 116 a of the digital camera 100. Even when the amount of documents is large, the extracted sentence is short, so that the capacity recorded in the digital camera 100 can be reduced. As described above, in addition to sentence and title text data, author name text data may also be recorded.

  On the other hand, when the title of the literary book has not been input in the determination in step S1, the control unit 301 determines whether or not a content reproduction instruction has been given by an operation of the PC 500 or the like by the user (step S4). When the content reproduction instruction is given in the determination in step S4, the control unit 301 reproduces the content such as an image recorded in the recording unit 303 (step S5). Thereafter, the control unit 301 ends the process of FIG. On the other hand, if it is determined in step S4 that no content reproduction instruction has been issued, the control unit 301 ends the processing in FIG. 4 without extracting a sentence or reproducing the content.

  FIG. 5 is a flowchart showing control on the digital camera 100 side in the communication system of FIG.

  The MPU 101 of the digital camera 100 determines whether or not a shooting instruction has been made by determining whether or not the release switch of the operation unit 102 has been operated by the user (step S11). If it is determined in step S11 that no shooting instruction has been given, the MPU 101 determines whether or not a reproduction instruction has been given by the user operating the operation unit 102 (step S12). If it is determined in step S12 that a reproduction instruction has not been given, the MPU 101 determines whether or not a through image display instruction has been given by the operation of the operation unit 102 by the user (step S30). When the through image display instruction is given in the determination of step S30, the MPU 101 starts displaying the through image for framing (step S13). On the other hand, when the through image display instruction is not given in the determination in step S30, the MPU 101 determines whether there is data transmission from the server 300 (step S31).

  When it is determined in step S31 that there is data transmission from the server 300, the MPU 101 receives sentence and title text data via the communication unit 118 (step S32). When all the data reception is completed, the process returns to step S11. The sentence and title text data received via the communication unit 118 is stored in the sentence database 116a.

  After starting the live view display, the MPU 101 determines whether or not an instruction to display a sentence text has been issued by determining whether or not the user has operated the sentence display switch 102a (step S14). If it is determined in step S14 that a sentence text display instruction has not been issued, the process returns to step S11, and the MPU 101 determines again whether or not a shooting instruction has been issued by the user. On the other hand, in the determination in step S14, when an instruction to display a sentence text is given, the MPU 101 performs vertical / horizontal determination of the screen (step S15). This is a process for displaying the text of a sentence so that the user can read it correctly. For example, when shooting in the daytime or under lighting, a bright part in an image displayed through is detected, and this bright part is detected. Determined to be on the screen. Further, face detection may be performed by the face detection circuit 114, and the height and breadth of the screen may be determined from the face orientation. Alternatively, the vertical and horizontal directions of the screen may be determined by detecting the posture of the digital camera 100 (whether it is held in a vertical position or a normal position) using an angular velocity sensor or the like.

  After completing the vertical / horizontal determination of the screen, the MPU 101 performs face detection by the face detection circuit 114 (step S16). If face detection is performed during the vertical / horizontal determination of the screen in step S15, the process in step S16 can be omitted. After step S16, the MPU 101 determines whether or not a face is detected in the image by the face detection circuit 114 (step S17).

  If a face is detected in the determination in step S17, a display as shown in FIG. In this case, in order to avoid displaying the text on the face, the MPU 101 sets the display position of the sentence text and the title text to a position other than the face position detected in step S16 and The orientation is set according to the orientation of the screen determined by the vertical / horizontal determination (step S18). In the case of the display as shown in FIG. 3C, the text may be buried in the background. Therefore, the MPU 101 sets the display color of the text to the complementary color of the background at the text display position. And the text of the title are displayed on the display panel 111 together with the through image (step S19).

  If no face is detected in the determination in step S17, the text is displayed at a position different from the through image as shown in FIG. That is, the MPU 101 positions the text of the sentence and the text of the title separately from the frame on which the through image of the display panel 111 is displayed (for example, the left side of the screen. (Step S20).

  After step S19 or step S20, the MPU 101 converts the text position into an operation such as a text position changing operation, a text vertical writing display / horizontal writing display switching operation, a text display color changing operation, and the like. It is determined whether or not any such change operation has been performed (step S21). For this change operation, a dedicated operation member for performing each change operation may be provided in the operation unit 102. For example, an item for changing text may be set in the menu screen of the digital camera. You may make it leave. When the change operation is not performed in the determination in step S21, the MPU 101 performs the process in step S23. On the other hand, when the change operation is performed in the determination of step S21, the MPU 101 switches the display position and display color of the text, or the vertical writing display and the horizontal writing display of the text according to the operation instruction from the user (step S22). . In this way, the user can enjoy shooting while confirming the position and effect of the text to be combined during recording.

  After that, the MPU 101 determines whether or not a text text switching operation to be displayed on the display panel 111 is performed by the operation of the operation unit 102 by the user (step S23). If it is determined in step S23 that the text switching operation has not been performed, the process returns to step S11, and the MPU 101 determines again whether or not a shooting instruction has been given by the user. On the other hand, when the text switching operation is performed in the determination in step S23, the MPU 101 switches the sentence text to be displayed on the display panel 111 to the next text (step S24), and then returns to step S11. Note that after the text of all sentences is displayed, the first text may be displayed again, or the text display may be terminated.

  Further, in the determination in step S11, when a shooting instruction is given, the MPU 101 starts a shooting operation and acquires image data (step S25). After the photographing operation is finished, the MPU 101 determines whether or not the sentence text is displayed at the time when the photographing instruction is given, thereby synthesizing the sentence and title text data with the image data obtained by the photographing operation. It is determined whether or not (step S26). In the determination of step S26, when combining text data, the MPU 101 causes the text combining circuit 112 to combine the text data of the sentence and the title with the image data and then record them on the recording medium 117 (step S27). Note that the text composition position, text color, and whether the text is written vertically or horizontally are set by the user at the time of through image display. On the other hand, if the text data is not synthesized in the determination in step S26, the MPU 101 records only the image data on the recording medium 117 (step S28). After the image data is recorded on the recording medium 117, the MPU 101 ends the process of FIG.

  In the determination of step S12, when an image reproduction instruction is issued, the MPU 101 expands the image data selected by the user via the compression / expansion unit 115 and causes the display panel 111 to display the expanded image ( Step S29).

  As described above, according to the present embodiment, just by inputting the title of a literary book, a sentence related to a subject that is likely to be photographed is extracted from the literary book. At the time of shooting, the text is synthesized with the image that the user is about to shoot by simply selecting a desired sentence from the sentences extracted from the server and recorded on the recording medium 117. As a result, it is possible to easily create content in which an image and text are combined. Also, if the literary book is like a guide book, it is often written along the route. Therefore, by displaying the sentence text in the order in which it appeared in the literary book as in this embodiment, if the user shoots in that order, even if he goes on a trip without making a detailed plan, You can travel around sightseeing spots efficiently. If shooting is performed in accordance with the sentences in the same literary book in this way, images can be shot with a consistent theme, and more impressive content can be created.

  Also, if there is a person's face, avoid the face part, change the color of the text so that the text is not assimilated in the background, or change the direction of the text according to the orientation of the screen, The user can create content without necessarily considering the position and color of the text.

  Here, in the embodiment described above, the title of the literary book is combined with the image together with the sentence text, but the author name may also be combined. In the above-described embodiment, the sentence text and the title text are synthesized as a unit. However, the title text may be synthesized only in the first sentence.

  Although the present invention has been described above based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications and applications are naturally possible within the scope of the gist of the present invention. For example, in the above-described embodiment, processing for extracting sentence text data from document data of a literary book is performed in the server 300, but if the digital camera 100 is provided with the database 400, sentence text data is processed in the digital camera 100. Can also be extracted.

  Further, the above-described embodiments include various stages of the invention, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some configuration requirements are deleted from all the configuration requirements shown in the embodiment, the above-described problem can be solved, and this configuration requirement is deleted when the above-described effects can be obtained. The configuration can also be extracted as an invention.
