Description

  The present invention relates to a content playback apparatus that plays back content data, for example, content data such as audio, still images, and moving images. More specifically, the present invention relates to content according to position information and time information associated with individual content. The present invention relates to a content playback apparatus that plays back video.

  With respect to image capturing methods, particularly still image capturing methods, it is much easier and simpler than the use of conventional silver halide films with the spread of digital cameras. Furthermore, mobile phones, PDAs, mobile phones When a digital camera is built in a personal computer or the like, it is possible to take not only a still image but also a moving image very easily at any time and anywhere. This also applies to voice.

  However, if still images and moving images can be taken too easily, there is a high possibility that it is unclear when and where each individual image was taken. As for the shooting time, it is possible to attach the shooting time data to the digital data of the shot image, but for the shooting location (position), you can rely on the photographer's memory or enter the place name as character data each time. Need to be matched.

  This means that when playing back an image shot with a digital camera or the like, it is possible to search by shooting time (date and time), but when searching at the shooting location, the place name associated as character data It just means that it may be possible to search on. In addition, even when an image of a photograph taken with a silver halide film is captured as digital data in a personal computer or the like, even if the photographing time (date and time) is imprinted in the image alone, the photographing time (date and time) , You can not search by shooting location. Furthermore, in many cases, images downloaded from the Internet, images sent by e-mail, etc. are unknown in shooting time (date and time) and shooting location. Therefore, for such image data, it is necessary to input the shooting time (date and time) and place name as characters.

  The above situation is basically the same not only for image data but also for audio data. By the way, audio data is generally considered to be music data, but other human voices such as interviews, conferences, lectures, and other various hobbies or specialized research fields (wild birds, etc.) Various voice data are collected in the wild animals squealing, traveling sounds of railway vehicles, automobiles, etc., and flight sounds of airplanes, etc., and when they are played back, search at the recording time (date and time) and recording location. It is convenient if you can.

  Patent Document 1 discloses an invention in which a standby screen is automatically changed according to the position of a mobile phone. However, in the invention disclosed in Patent Document 1, only the standby screen is displayed according to the position of the mobile phone.

  Patent Document 2 discloses an invention in which the ringing melody is automatically changed according to the position of the mobile phone. However, in the invention disclosed in Patent Document 2, only the incoming melody is displayed according to the position of the mobile phone.

  Furthermore, various video and audio data corresponding to the current position, for example, music corresponding to the current position, various guidance corresponding to the current position, and the like are automatically reproduced with images and / or sounds while moving in a car. If it is convenient. Such functions are partially put into practical use in, for example, car navigation systems, but images and / or sounds to be reproduced are generally determined by car navigation system manufacturers or map data manufacturers and providers. If you want to prepare, it is a dressing up. Accordingly, it is impossible to reproduce, for example, an image recorded when a driver of a car travels before or an impression recorded as sound according to the current position while the car is running.

  However, it is not the guidance of dressing up by the car navigation system, but the driver himself / herself, friends, acquaintances, such as guidance of the spot with a good view and images at that spot, guidance of the restaurant you want to revisit, etc. Can be used, a method of using a car navigation system different from the conventional one can be used. This further makes it possible to create a personal navigation system for special hobbies or research areas that are not generally covered by commercially available car navigation systems. Specifically, for example, research on Jizo, Doujin, etc., wildlife research (for example, recording of the sound of wild birds), and customizing the navigation system for personal use or for the purpose of gathering insects. Or newly created.

  In addition, it is possible to reproduce image and audio data in the same manner by a mobile phone having a position detection function (specifically, a GPS function), a PDA, etc., regardless of the car navigation system as described above. Furthermore, in recent years, a man navigation system applying the concept of a car navigation system has been put into practical use (see Patent Document 3). This man navigation system is a navigation system for pedestrians mainly using a mobile phone. For example, not only simple route guidance but also information on transportation and restaurant guidance is reproduced as image and audio data. However, even in this man navigation system, the reproduced image, audio data, etc. are still the products of the device manufacturer or the service provider.

  Furthermore, even desktop type personal computers can reproduce image and audio data by specifying position information. Specifically, even in conventional map software, a user designates a position on a map image displayed on a display device of a personal computer and associates it by registering data such as arbitrary images, sounds, and texts. Is possible. However, with such map software, only registered data can be displayed (reproduced), and it cannot be denied that registration work becomes complicated when there are a large number of data such as target images.

Furthermore, there is an application program that can reproduce preset music as BGM when a slide show is executed on a personal computer. In such an application program, a plurality of image data are grouped, and a plurality of image data included in each group are reproduced and displayed as a series of slide shows. Yes. Therefore, when using such an application program, it is necessary to group image data to be subjected to a slide show in advance (generally referred to as an album), and specify music to be used as BGM for each group. It is also necessary to keep it. Therefore, when a slide show is executed, the same photograph (image data) grouped in advance is reproduced and displayed every time, and the same music is used as BGM.

  Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof. FIG. 1 is a functional block diagram showing an example of the internal configuration when the content reproduction apparatus according to the present invention is applied to a mobile phone.

  The cellular phone 1 includes a control unit 11 constituted by a CPU or MPU, a communication unit 12 capable of communicating with the Internet, for example, a position detection unit 13 for detecting the current position using GPS or the like, a numeric keypad, a cross key, and the like. Operation unit 14, a time measuring unit 15 that measures absolute time (year / month / day / hour / minute / second) as a current time, a ROM 16 that stores a program for basic control of the mobile phone 1 by the control unit 11, and a control unit 11 RAM 17 for temporarily storing various data generated by the control by the display, display unit 18 using a liquid crystal panel, etc., non-volatile that can be rewritten and can retain data even when the power is cut off A still image and / or moving image is captured by using a memory 19, a transmission / reception unit 20 for a normal call, an image sensor such as a CCD, and digital data ( Imaging unit 21 which converts and outputs to JPEG, MPEG format, etc., external interface 22 for communicating with other devices such as personal computers via cables or infrared communication (IrDA), etc. A microphone 23 for recording, a speaker 24 for audio output, a data conversion unit 25 for converting the data format between various data formats, and the like are provided.

  The analog audio signal input from the microphone 23 is converted into a digital audio signal by an A / D (analog / digital converter) 230. Further, the sound uttered from the speaker 24 is given to the speaker 24 after a sound signal of digital data is converted into an analog sound signal by a D / A (digital / analog converter) 240. Reference numeral 241 denotes an earphone (headphone) jack. By inserting a plug of an appropriate earphone (headphone), it is possible to output sound from the earphone (headphone) instead of the speaker 24.

  For example, in the case of audio data, the data conversion unit 25 further converts digital audio data obtained by digitizing analog audio data into, for example, the MP3 format, and vice versa, or is input from the external interface 22. Or convert music CD format data to MP3 format. Further, in the case of image data, the data conversion unit 25 receives image data captured by the imaging unit 21, various formats received via the Internet or input from the external interface 22, such as a bitmap, GIF, etc. Are converted into a format for handling in the mobile phone 1, such as JPEG format, and vice versa.

  The configuration of the mobile phone 1 as described above is basically the same as that of a known mobile phone. Note that the RAM 17 can also be used as the nonvolatile memory 19, and the ROM 16 and the RAM 17 can also be used as the nonvolatile memory 19. In addition, the microphone 23 and the speaker 24 can also be used as a microphone and a speaker that are normally provided in the transmission / reception unit 20.

  Incidentally, a content database (hereinafter referred to as DB) 190 and a content processing program 195 as a computer program are stored in an appropriate storage area of the nonvolatile memory 19. The content DB 190 stores still image data, moving image data, audio data (music, human voice, etc.), and text data as compressed digital data. The content processing program 195 registers content data in the content DB 190 and searches for content data from the content DB 190 in accordance with the procedure described later.

  The content DB 190 includes a content storage area 192 that actually stores content data, and an index area 191. FIG. 2 is a schematic diagram showing the contents stored in the index area 191. As schematically shown in FIG. 2, the index area 191 stores, for each content, information for identifying each ID, storage address, position information, time information, content type, and classification in association with each other. .

  Specifically, the storage address is an address in the content storage area 192 where each content is stored. Specifically, the position information is information indicating the longitude and latitude detected by the position detection unit 13 when each content is acquired. Specifically, the time information is information indicating the year / month / day / hour / minute / second measured by the time measuring unit 15 at the time when each content is acquired. Specifically, the content type is an identifier indicating whether each content is a still image, a moving image, audio, or text. The classification is information representing whether each content is information about restaurants, for example, information for navigation (direction guidance), music, or the like.

  Therefore, when content data is read from the content DB 190, it is possible to search the index area 191 with position information and / or time information and read the corresponding content data from the content storage area 192. The content data read from the content storage area 192 is displayed on the display unit 18 after the data format is converted by the data conversion unit 25 according to the identifier indicating the content type, or is uttered as sound from the speaker 24. The controller 11 determines whether or not. There are also contents in which images (still images, moving images) and sound are integrated.

  When the still image or moving image data captured by the imaging unit 21, the audio data input from the speaker 23, and the text data input from the operation unit 14 are stored as content in the content DB 190, the position detection unit simultaneously The position information related to the current position detected by 13 and the information (time information) of the absolute time (year / month / day / hour / minute / second) measured by the timer unit 15 are stored in association with each other.

  In addition, the content DB 190 can download still image data, moving image data, audio data, and text data from the Internet by the communication unit 12, or can receive them by e-mail, and can also receive other data via the external interface 22. It can also be imported from various devices such as a personal computer. With regard to such data, the content DB 190 stores still images in association with position information and time information when they are attached. However, in the case where such data is not attached with position information and / or time information, the content DB 190 stores the position information and time information from the position detection unit 13 and the time measuring unit 15 at the time of storing the data. Or may be left blank if no location information and / or time information is attached.

  The content type can be determined to be a still image or a moving image according to a mode (still image mode or moving image mode) at the time of image capturing regarding the still image and moving image data acquired from the image capturing unit 21. It is possible to determine that the voice data input from is text, and the text data input from the operation unit 14 can be determined to be text data. In addition, regarding the data taken in via the communication unit 12 or the external interface 22, the file type is attached to the data file, so that the content type can be identified.

  In addition, regarding the data stored in the content DB 190, the position information and time information associated with each of the data can be changed, deleted, added (when there is no data from the beginning), and the like by the operation of the operation unit 14.

  By the way, the position information is basically information on longitude and latitude detected by the position detector 13. Accordingly, when changing the position information or adding the position information to the data to which no position information is attached, it is necessary to input the longitude and latitude information by some method. Various techniques can be used for this purpose. For example, a place name stored in advance in the non-volatile memory 19 by inputting characters from a municipality name, a station name, or a famous place name or facility name from the operation unit 14. A method for reading out longitude and latitude such as a central point of a municipality from a database or a method in which the communication unit 12 downloads from a specific website through Internet communication, or map data stored in advance in the nonvolatile memory 19 or the communication unit 12 through Internet communication A method of designating map data downloaded from a specific website on a map image displayed on the display unit 18 can be considered. In any case, it is possible to obtain the longitude and latitude as the position information by a conventionally known technique, and it may be rough information to some extent instead of strict information.

  Also, the time information can be changed or added. The time information is changed by setting a future time in advance to automatically reproduce data at that time.

  FIG. 3 is a flowchart showing a basic processing procedure when various data is acquired as content data by the mobile phone 1 as the content reproduction apparatus of the present invention as described above, and is controlled by the control unit 11 according to the content processing program 195. Executed.

  The mobile phone 1 normally performs processing such as standby for reception (NO in step S11, step S12). However, when the user gives an instruction to acquire data by operating the operation unit 14 (YES in step S11). ) Get the data. Here, the acquisition of data is, for example, imaging of an image (still image and / or moving image) by the imaging unit 21 or recording of sound input from the microphone 23.

  When the data is acquired, the control unit 11 registers the acquired data, the position information detected by the position detection unit 13 at that time, and the time information measured by the time measuring unit 15 in the content DB 190 (step S13). ). As described above, the acquired data itself is stored in the content storage area 192 of the content DB 190, and the address and position information indicating the storage position of the data in the content storage area 192, time information, content type, etc. are stored in the index area 191. The The user can input the classification of the data by operating the operation unit 14 when the data is acquired.

  Thus, the position information and / or time information of the content data registered in the content DB 190 can be changed by the user's operation (YES in step S14). When changing the position information and / or time information, the user operates the operation unit 14 to reproduce the data of the desired content, and in the meantime (in the case of image data and text data, it is displayed on the display unit 18. In the meantime, if the position information and / or time information is re-inputted (while being reproduced from the speaker 24 or the earphone jack 241 in the case of audio data), the position information and / or time information is changed (step S15). The process is returned to S14. The changed position information and / or time information is registered in the corresponding field of the index 191 of the content DB 190.

  Therefore, the position information and / or time information of the desired content data is changed until the user performs an operation that does not change the position information and / or time information of the content data registered in the content DB 190 (NO in step S14). Can be repeated.

  Although not described in the flowchart, downloading various data from a specific website on the Internet via the communication unit 12 and registering it as content data in the content DB 190 is also received by e-mail. Various data can be registered as content data in 190, and further, various data can be acquired from various devices such as personal computers and audio devices via the external interface 22 and registered as content data in the content DB 190. Of course, it is also possible. Furthermore, if the mobile phone 1 has a TV reception function (mainly a digital terrestrial TV reception function) or a radio broadcast reception function, it is also possible to register music data received from the broadcast in the content DB 190. is there.

  FIG. 4 is a flowchart showing a processing procedure when content is played back by the mobile phone 1 which is the content playback device of the present invention.

  First, when the user selects automatic reproduction (YES in step S21), the control unit 11 acquires position information at that time from the position detection unit 13 (step S22). Then, the control unit 11 automatically reads out content data corresponding to the acquired position information from the content DB 190 at predetermined intervals and sequentially reproduces the data (step S23). Specifically, the control unit 11 searches the index area 191 of the content DB 190 using the position information detected by the position detection unit 13 as a key, and if position information within a predetermined range is registered, it is associated with the position information. And the content data is read from the content storage area 192 according to the address. The content data read from the content DB 190 in this way is reproduced and output from the display unit 18 and / or the speaker 24. It should be noted that audio content can be reproduced from an earphone (headphone) (not shown) via an earphone (headphone) jack 241 instead of the speaker 24. This reproduction process is repeated (NO in step S24) until the user instructs the end (YES in step S24). Therefore, when all the content data corresponding to the acquired position information is reproduced, the same data is reproduced again.

  When the user selects manual regeneration instead of automatic regeneration (NO in step S21, YES in S31), the control unit 11 acquires position information at that time from the position detection unit 13 (step S32). Then, the control unit 11 reads out and reproduces one of the content data corresponding to the acquired position information from the content DB 190 according to the user's manual operation (step S33). In this case, when the user performs a predetermined operation on the operation unit 14, the next data is reproduced. This reproduction process is repeated (NO in step S34) until the user instructs the end (YES in step S34). Therefore, after the content data corresponding to the acquired position information is completely reproduced according to the operation of the operation unit 14 by the user, when the user gives an instruction for reproduction by the operation of the operation unit 14, the same data is again displayed. Played. When the user does not select any process (NO in S31), the control unit 11 executes another process (step S35) and returns the process to step S21.

  The above is the basic operation of the mobile phone 1 as the content reproduction apparatus of the present invention. Therefore, if a large amount of content data is stored in the content DB 190 as described above, the mobile phone 1 uses the location information and / or time information representing the current location and / or time at that time as a key. By searching, it becomes possible to automatically reproduce various contents by various methods. Therefore, the following various usage methods are possible for the user. Some of them are described in detail below.

  First, use for acquiring various information at a specific point is conceivable. In this case, the user himself / herself, for example, at a place where he / she works, a business trip where he frequently travels, etc., for example, information on restaurants (images of the exterior of the store, images of menus, images of dishes themselves, etc.) Then, “Restaurant” is designated as the classification and registered in the content DB 190 as content data. At this time, store impressions, food impressions, and the like may be registered in the content DB 190 as character data or audio data as content data. Needless to say, when such data is registered in the content DB 190, the position information detected by the position detector 13 and the time information measured by the timer 15 are associated with each other.

  Then, if the user designates “restaurant” as the classification at the point where such information is registered and instructs the reproduction of the content, the control unit 11 detects the position detected by the position detection unit 13 at that time. Content data with position information within a certain range of latitude and longitude centered on information (latitude and longitude), for example, a radius of several kilometers (a difference in longitude and latitude can be easily converted to an approximate distance) Can be automatically and sequentially displayed at intervals of a few seconds in the order of oldest or newest time information attached thereto. By viewing this slide show, the user can decide a store to eat, or conversely, can select a store other than the store reproduced in the slide show.

  The method of using the content reproduction apparatus of the present invention as described above can be executed by the basic operation example according to the flowcharts shown in FIGS.

  Moreover, the utilization method as a man navigation system is also possible. For example, when the user first goes to a place, the image data and text are captured while the imaging unit 21 captures the target building (landmark) while traveling from the nearest station to the destination, and the traveling direction at the intersection, etc. Data or user's own audio data is registered as content data. Thus, when the user goes to the same place next time, or when another person goes to the place, the data of such content is manually set in order of time information from the nearest station, or according to the position information. If it is displayed in the slide show method of sequentially displaying, the man navigation system can be used.

  FIG. 5 is a flowchart showing a processing procedure at the time of data acquisition when the content reproduction apparatus of the present invention is used as the man navigation system as described above. The processing shown in this flowchart is executed by the control unit 11 in accordance with the content processing program 195.

  First, when the user designates the man navigation system registration mode by operating the operation unit 14 at a place such as the nearest station of the destination, the nearest bus stop, or the like to start navigation, the control unit 11 registers the man navigation system. A mode is set (YES in step S41). In other cases (NO in step S41), the control unit 11 executes other processing such as incoming call waiting processing (step S42).

  After the man navigation system registration mode is set, the control unit 11 waits for data acquisition (NO in step S43). When data acquisition (acquisition of still images and moving image data by the imaging unit 21, acquisition of audio data by the microphone 23, acquisition of text data by the operation unit 14, etc.) is performed by the user's operation (YES in step S43). The control unit 11 acquires the position information and time information at that time from the position detection unit 13 and the time measuring unit 15 (step S44), respectively, that is, acquired data, position information, time information, classification (man navigation) All the classifications while the system registration mode is set become man navigation) are registered in the content DB 190 (step S45).

  As described above, until the user arrives at the destination, the user registers the image of the intersection, such as a building that becomes a landmark, and information on the traveling direction, etc. as image data, audio data, text data, or a combination thereof. (NO in step S46, return to step S43). When the user arrives at the destination and instructs the end of the man navigation system registration mode by operating the operation unit 14 (YES in step S46), the control unit 11 ends the man navigation system registration mode.

  FIG. 6 and FIG. 7 are flowcharts showing processing for reproducing the content data for the man navigation system registered as described above, in other words, processing procedures when the mobile phone 1 is actually used as the man navigation system. It is. 6 and 7 is executed by the control unit 11 in accordance with the content processing program 195.

  When the user designates the man navigation system execution mode by operating the operation unit 14 at the starting point of navigation such as the nearest station or the nearest bus stop at the destination, the control unit 11 sets the man navigation system execution mode (YES in step S51). ). In other cases (NO in step S51), the controller 11 executes other processing such as incoming call waiting processing (step S52). In response to the setting of the man navigation system execution mode, the control unit 11 acquires the position information detected by the position detection unit 13 (step S53), and converts the acquired position information from the content data registered in the content DB 190. The data of the content with the oldest time information in the corresponding man navigation classification is retrieved and reproduced (step S54). Thereafter, until the next data reproduction operation is performed (NO in step S55), the display state is maintained as it is.

  If the data to be reproduced here is, for example, an image of a station square and the traveling direction is unknown, the user operates the operation unit 14 to instruct reproduction of the next data (YES in step S55). In response to this, the control unit 11 obtains position information from the position detection unit 13 again (step S56), and searches the content DB 190 for man navigation classification data corresponding to the obtained position information (step S57). When a plurality of corresponding data are registered (YES in step S58), the control unit 11 determines whether or not data being reproduced is included (step S59). If currently reproduced data is included (YES in step S59), the control unit 11 reproduces data whose time information is next to the time information of the data being reproduced (step S60). ).

  Therefore, as described above, when the image of the station square is first displayed and the data reproduced next is text data such as “go right to the station square”, the user follows the text data according to the text data. Go to the right.

  As a result of the search in the previous step S57, if the corresponding data does not exist (NO in step S58, NO in S61), the control unit 11 executes the process in step S60 described above, so that it has no relation to the position information. The data having the time information next to the data currently being reproduced is reproduced. Such a situation corresponds to a situation where the user (mobile phone 1) is located between two points where data was acquired in the registration mode, and the user usually knows the traveling direction (direction). There are many cases. Therefore, the user only has to proceed to the point corresponding to the data being reproduced. However, if the user determines that he has lost his way, the user can give an instruction to operate the operation unit 14 to reproduce the previous data (YES in step S63). In response to this, the control unit 11 reproduces the data reproduced immediately before the currently reproduced data (step S64), so that the user can return to the position where the reproduced data is acquired.

  If only one corresponding data exists as a result of the search in the previous step S57 (NO in step S58, YES in S61), the data is currently being reproduced, but the control unit 11 The data currently being reproduced is reproduced (step S62). In this case, since there is only one piece of data acquired at that point in the registration mode, the user is forced to determine the traveling direction according to the data. However, normally, when there is only one piece of data at such a single point, the data whose traveling direction can be determined from the data at the time of data acquisition should be acquired. However, if the user determines that he has lost his way at this time, the user can give an instruction to reproduce the previous data by operating the operation unit 14 (YES in step S63). In response to this, the control unit 11 reproduces the previously reproduced data (step S64), so that the user can return to the position where the reproduced data is acquired.

  By the way, in the above-described step S59, when the currently reproduced data is not included in the plurality of data searched in step S57 (NO in step S59), the current position is the position where the currently reproduced data is acquired. Means that there are a plurality of pieces of data obtained at different positions and at the current position. Therefore, in this case, the control unit 11 reproduces the data with the oldest time information (step S66), and then proceeds to the above-described step S63 to obtain a plurality of data corresponding to the current position. It becomes possible to reproduce in order of the acquired time.

  As described above, when the user gives an instruction by operating the operation unit 14 to sequentially reproduce the next data in accordance with the data (image, text, voice) reproduced by the mobile phone 1 (NO in step S63). , NO in S65), since the user can finally arrive at the destination, the execution mode of the man navigation system is terminated at that time (YES in Step S65).

  The use of such a cellular phone as a man navigation system has already been provided with a service that provides route guidance by designating a starting point and a destination point, as in the car navigation system, mainly in urban areas. However, in the present invention, unlike this, the user himself can create and use it for an extremely personal purpose.

  Further, not as a simple man navigation system, for example, an image captured by the image capturing unit 21 using landmarks such as characteristic terrain and trees during hiking and trekking as landmarks are registered as content data, and at the same time, impressions are made by text or voice. Can be registered as content data, and further registered as content data in the form of images, texts, or voices in which direction the branch road has been reached is also possible. If such content data is registered, not only the user himself, but also other people will not be lost when hiking or trekking the same course next time. If it happens, or if you are unfortunately lost, you can quickly and appropriately deal with it.

  In addition to the above route guidance such as hiking and trekking, various hobby usage methods are possible. For example, the location where the route was collected together with the directions when collecting plants, insects, etc., and the images of the collected plants or insects were registered as content data. Register as If such content data is registered, it goes without saying that the user himself / herself next goes to the same location to collect plants and insects, but other people can collect plants and insects to that location. It can also be used when going.

  Of course, the use for the purpose of photography itself is also possible. For example, if the user likes a cat, an image of a cat imaged at random using the imaging unit 21 is registered as content data. When a large number of such cat image content data is registered, if the user reproduces the cat image at an arbitrary place, the cat images captured in the past around the current position at that time will be displayed as a slide show. It is possible to look for those cats. Such a method of use can be applied to other cases, for example, when taking images of Jizo-sama, Dosojin, Sakai-inu, etc. as a hobby, and also suitable for hobbies called so-called on-the-road observation, which has been popular recently. ing.

  Still further, when the photograph itself is photographed with a silver salt film camera or a digital camera, an image photographed at the same angle by the imaging unit 21 of the mobile phone 1 is registered as content data, and the photographing location and the photographing time are also recorded. It is also possible to use a situation in which the situation and photographing data (shutter speed, lens aperture value, lens used, etc.) are registered as content data in text or sound. If such content data is registered, it goes without saying that the user himself / herself goes to the same place for the next photo shoot, but also when other people go to the photo shoot for that place. It becomes possible. It is also possible to use image data captured by the mobile phone 1 as a thumbnail for indexing a photograph taken with a silver salt film or a digital camera.

  Furthermore, even when the mobile phone 1 is used as a headphone stereo, music data downloaded in advance via the Internet via the communication unit 12 and music acquired from another personal computer or audio device using the external interface 22 If the mobile phone 1 has a TV reception function (mainly a digital terrestrial TV reception function) or a radio broadcast reception function, the music data received from the broadcast is registered in the content DB 190. Is possible.

  The music data registered in the content DB 190 in this way can be attached with position information at the time of registration, but as described above, the user can change it to arbitrary position information. . Therefore, the user simply gives an operation of playing music to the mobile phone 1 by assigning position information to some music corresponding to a specific point within the range in which he / she moves. It becomes possible to listen to the corresponding music. This means that when the user moves on a train, a bus, a private car, etc. as well as on foot, the music to be played automatically changes according to the moving state. Therefore, for example, depending on when you arrive from your home in the morning, when you arrive at your nearest station, when you are on the train, when you arrive at your nearest station, when you arrive at your office, Alternatively, the music played in the reverse order can be automatically changed from one to the next.

  For example, if you are devoted to reading on a train, you may get over without notice at the nearest station of your work or home, or at a transfer station, but you can use the mobile phone 1 as described above. (In this case, of course, the user needs to use earphones or headphones), even if the user is devoted to reading on the train, for example, the music played will reveal the current location, so get over the train Such a fear is eliminated.

  In the method of using the mobile phone 1 as described above, it is of course possible to change the music to be played according to time information instead of position information. In this case, for example, for a general worker, the schedule at work, that is, the time to leave home, the time to get on the train, the time to get off the train, the time to arrive at the work place, etc. are often almost constant. Therefore, if the time information of the music data registered in the content DB 190 is set so that different music is played at each time, the user of the mobile phone 1 works after leaving the house in the morning. It is also possible to sequentially play different music corresponding to the normal schedule until the arrival.

  As for the image data, the reproduction method intended by the user can be achieved by arbitrarily changing the position information as described above. For example, if you attach the company's location information to the face data of the employee of the supplier's company, image data such as business cards, and text data such as name, title, past transaction status, etc. If the slide show is executed during the time until the negotiation starts, the past transaction status, the face of the person in charge, etc. can be confirmed.

  Furthermore, it is possible to simply use a slide show of images according to the current position. For example, if photos taken when the user has traveled in the past are registered in the content DB 190 in association with the location information at the time they were taken (the image data taken by the imaging unit 21 and the position detection unit 13 The detected position information may be automatically associated and registered in the content DB 190. For example, image data of a photograph taken with a silver salt film camera or a digital camera is taken in from the outside, and position information is given. It may be registered in the content DB 190), and when the user travels to the same place again, it is also possible to automatically reproduce and display as a slide show the photos taken last time (or even earlier) according to the position information. .

  By the way, it is assumed that the desktop type personal computer does not move except when the installation location is changed indoors or the user moves away. Therefore, a desktop personal computer does not need to acquire its own position information, apart from time information, and usually does not have such a function. On the other hand, instead of a slide show using a conventional slide film, a slide show using a personal computer has been widely used. In recent years, a slide show can be performed by connecting a personal computer to a projector. Furthermore, in recent years, it has become possible to use a personal computer as a device having a function equivalent to that of a music playback device such as a CD player by storing a large amount of music data on a hard disk or the like.

  Under such circumstances, there are also application programs that can reproduce music set in advance as BGM when a slide show is executed. In such an application program, a plurality of pieces of image data are grouped and a plurality of pieces of image data included in each group are reproduced and displayed as a series of slide shows. At this time, music reproduced as BGM is fixedly associated. Therefore, when using such an application program, it is necessary to group image data to be subjected to a slide show in advance (generally referred to as an album), and specify music to be used as BGM for each group. It is also necessary to keep it.

  For example, in the case where photos taken every time a user travels are displayed and reproduced as a slide show on a personal computer, for example, whether image data of photos taken in a single trip are grouped as slide show targets. Alternatively, it is necessary to group image data of photographs taken at different visiting places in one trip as a slide show target, and to set music to be used as BGM for each group.

  On the other hand, in order to make the slide show BGM different music each time, the BGM is not set in advance for the slide show, but an operation for playing music with an application program for playing music and a slide show with an application program for slide show are performed. Two operations, the operation to be executed, may be performed separately on the personal computer, and both may be processed in parallel. However, in this case, there is a possibility that the BGM ends while the slide show is being executed, or conversely, the music playback does not end even after the slide show is ended.

  Therefore, in one embodiment of the present invention, when a slide show is executed, music corresponding to position information attached to image data to be reproduced and displayed can be automatically reproduced as BGM. Although the present embodiment is mainly assumed to be implemented by a desktop personal computer, it can of course be implemented by a mobile phone, a PDA, a car navigation system, or the like.

  FIG. 8 is a block diagram showing an example of the internal configuration of a personal computer as the content reproduction apparatus of the present embodiment. The internal configuration example of the personal computer shown in FIG. 8 is basically similar to the internal configuration example of the mobile phone shown in FIG.

  Specifically, the personal computer 100 includes a CPU 111, a communication unit 112 capable of communicating with the Internet, an operation unit 114 composed of a keyboard, a mouse, and the like, and a time measuring unit that measures the absolute time (year / month / day / hour / minute / second) as the current time. 115, ROM 116 that stores a startup program, RAM 117 that temporarily stores various data generated by control by the CPU 111, a display unit 118 that uses a liquid crystal monitor, etc. A hard disk drive (HDD) 119 as a non-volatile memory capable of holding data, an auxiliary storage device 120 such as a CD drive for reading a program, data, etc. from a portable recording medium such as a CD-ROM, Via cables with other devices such as digital cameras Te or external interface 122 for communicating with the infrared communications (IrDA) or the like, a speaker 124, etc. for the voice output. In the personal computer shown in FIG. 8, the function corresponding to the data conversion unit 25 provided in the mobile phone 1 shown in FIG. 1 is realized by software processing by the CPU 111.

  The sound uttered from the speaker 124 is given to the speaker 124 after the sound signal of digital data is converted into an analog sound signal by a D / A (digital / analog converter) 125. Reference numeral 126 denotes an earphone (headphone) jack. By inserting a plug of an appropriate earphone (headphone), it is possible to output sound from the earphone (headphone) instead of the speaker 124.

  The HDD 119 stores a content DB 190 and a content processing program 195 as a computer program similar to those in the case of the mobile phone 1 shown in FIG. Since the content DB 190 and the content processing program 195 are the same as the content DB and content processing program of the mobile phone 1 shown in FIG.

  9 and 10 are flowcharts showing a control procedure by the CPU 111 when a slide show is executed by the personal computer having the configuration shown in FIG. The CPU 111 executes the processing procedure of this flowchart according to the content processing program 195 stored in the HDD 119.

  For example, when the user performs an operation such as clicking a predetermined icon displayed on display unit 118 with the mouse of operation unit 114, CPU 111 starts executing the slide show (YES in step S71). If the start of the slide show is not instructed (NO in step S71), the CPU 111 executes another process in accordance with a user operation or the like (step S72).

  When an operation for starting execution of the slide show is performed, the CPU 111 determines whether or not a condition is set (step S73). Here, condition setting is performed (YES in step S73), and if the condition is period setting (YES in step S74), CPU 111 accepts setting of the period (step S75). The period accepted here may be, for example, a year unit such as “2002”, a month unit such as “January to June 2002”, or a lap unit or a day unit. In any case, the CPU 111 searches the content DB 190 in the order of time information using the period accepted in step S75 as a key (step S76).

  If the corresponding image data exists as a result of searching the content DB 190 (YES in step S77), the CPU 111 reproduces and displays the image data on the display unit 18 (step S78), and the position information attached to the image data is displayed. Corresponding music data, that is, music information to which the same position information is attached is searched from the content DB 190 (step S79). As a result of this search, if the corresponding music data is registered in the content DB 190 (YES in step S80), the CPU 111 reproduces and outputs the music data from the speaker 24 (step S81), and if not (in step S80). NO), the CPU 111 reproduces and outputs predetermined music data (step S82). In this case, by reproducing and outputting predetermined music data, the user can recognize that the music corresponding to the image is not registered in the content DB 190. However, the music data may not be played back, that is, the slide show may be executed without BGM, or the music data may be selected and played back at random.

  Next, the CPU 111 checks whether or not the position information attached to the image data has changed (step S83). However, when the first image data is reproduced and displayed, the processing in step S83 is not performed. Then, the CPU 111 stands by until a predetermined time set in advance as a time for displaying each image of the slide show elapses (NO in steps S83 and S85), and when the predetermined time elapses (NO in step S83, YES in step S85). ), The process returns to the previous step S77. While waiting until the predetermined time elapses, the image data displayed in step S78 continues to be displayed on the display unit 18, and the reproduction output of the music data reproduced and output in step S81 is continued. The

  If it is determined in step S85 that the predetermined time has elapsed, the CPU 111 returns the process to step S77. If there is next image data searched in the order of time information in step S76, the image data is displayed on the display unit 18. Are displayed and displayed in the same manner as described above. In this case, if the position information attached to the image data newly displayed on the display unit 18 is not changed from the position information attached to the image data displayed immediately before (NO in step S83), the CPU 111 performs music. As for data, the reproduction output state is continued as it is. However, if the position information attached to the image data newly displayed on the display unit 18 is different from the position information attached to the image data displayed immediately before (YES in step S83), the CPU 111 proceeds to step S79. Return processing. As a result, the music data corresponding to the position information attached to the newly displayed image data is searched from the content DB 190 in the same manner as described above, and the processes after step S79 are repeated.

  Through the processing described above, for example, when the user sets the period to a certain year, the image data of photographs taken by the user during the year is sequentially read out from the content DB 190 and displayed in the slide show format. While pictures of substantially the same position (for example, a sightseeing spot in a certain range) are sequentially displayed as a slide show, music corresponding to the position is reproduced and output as BGM. As BGM in this case, the user may give location information to a favorite song and register it in the content DB 190 in advance, for example, a station announcement recorded when the user actually traveled, a famous temple It may be the sound of a bell.

  When all the photos taken at one tourist spot are reproduced and displayed as a slide show, all the pictures taken at the tourist spot visited by the user are reproduced and displayed as a slide show. Therefore, when a photograph displayed as a slide show is switched from one tourist spot to another tourist spot, the BGM reproduced and output is automatically switched to a different music.

  If the user does not set conditions in step S73 (NO in step S73), the CPU 111 retrieves all image data from the content DB 190 in order of time information (step S91), and if the image data is registered. A slide show is executed (YES in step S77). In this case, the BGM corresponding to the images displayed on the display unit 18 as a slide show is also retrieved from the content DB 190 and reproduced and output in the same manner as described above.

Furthermore, when the user performs condition setting other than the period setting in step S74, for example, the condition setting is based on the position information (NO in step S74), the CPU 111 accepts the condition setting (step S92), and stores the content DB 190 with the set condition. Search is performed (step S93), and if image data satisfying the conditions is registered, a slide show is executed (YES in step S77). In this case, the BGM corresponding to the images displayed on the display unit 18 as a slide show is also retrieved from the content DB 190 and reproduced and output in the same manner as described above.
In any case, if the image data is not registered (NO in step S77), this process ends.

  As described above, according to the content reproduction apparatus according to the present invention, since the content is reproduced by searching with the position information and / or time information, instead of searching with a specific keyword as in the prior art, the user can A man navigation system can be created. In addition, a slide show that has been executed for image data that has been previously grouped in advance can be executed for, for example, image data of a photograph taken during an arbitrary period, or can be fixedly associated. It is also possible to automatically change the BGM that has been used according to the position information at which the photograph was taken.
