Description

  The present invention relates to a portable device having a position information acquisition function, an image photographing function, and a date / time information acquisition function. Furthermore, using the location information acquired using the location information acquisition function and the date / time information acquired using the date / time information acquisition function, retrieval of captured images captured using the image capture function and stored in the device It is related with the portable apparatus which performs.

  In recent years, mobile devices with camera functions, in particular mobile phone devices with camera functions, have become widespread, and the functions for taking still images and moving images have become basic functions of mobile phone devices. Along with this situation, as a technology for differentiating camera functions of mobile phone devices, there are competitions such as improvement in camera performance in the number of recorded pixels, improvement in the number of still images that can be recorded in the device, improvement in recording time of moving images, etc. Has been done.

  For this reason, mobile phone devices having a photographing function are used not only as a temporary memo, but also for taking commemorative photos and recorded photographs at travel destinations. As a result, in addition to the usage method, which requires only a short time from shooting to viewing, the user who took the image checks the state of the shot image to send the shot image attached to the e-mail from the shooting location. There have been new usage methods that take a long period of time from shooting to browsing, such as showing a shot image to a family member or friend after returning home, or printing a shot image on a paper medium.

  Conventionally, as a management method and search method of recorded images in a portable device, when a specific captured image is selected from a plurality of captured images recorded and stored in the device, the captured image is decompressed at a low resolution and is stored within one screen. There is a method for improving convenience when the user selects a desired captured image by simultaneously displaying a plurality of captured images (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 7-203360 (paragraphs 0021 to 6, FIGS. 2, 3)

  However, unlike devices such as personal computers, portable devices may not be able to be equipped with a high processing speed arithmetic processing circuit due to restrictions on the capacity of the device body. When such a portable device is used to search for a captured image described in Patent Document 1, if the number of captured images to be displayed on one screen is large, the resolution of each captured image is reduced. However, it takes time to process the entire image. In particular, under the situation where the file size of the photographed image is increasing due to an increase in the number of recorded pixels as at present, the processing delay becomes remarkable, which causes stress on the user. Further, since the number of shots that can be recorded in the apparatus is large, it is necessary for the user to update the display screen many times in order to find a desired shot image.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a portable device that can easily and quickly search for a desired image file from image files recorded in the device. It is in.

Photographing means for photographing an image;
Image file storage means for storing the captured image file;
Image display means for displaying the image file in order to view the image file;
Detection means for detecting current information;
For each image file, information storage means for storing shooting information of the image file and browsing history information of the image file in association with each other;
Search processing means for searching for the desired image file from the stored image file,
The search processing means searches for the desired image file using at least two pieces of information from the current information, the photographing information, and the browsing history information.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to search a desired image file easily and quickly from the image file recorded in the portable apparatus.

Embodiment 1 FIG.
The portable device described in this embodiment is characterized in that it searches for an image file using current information, shooting information, and browsing history information. Hereinafter, the portable device according to the present embodiment will be described.

<Structure>
FIG. 1 shows a configuration of a portable device 10 according to the present embodiment. The photographing means 1 is composed of an image sensor such as a CCD or a CMOS sensor. The information processing means 2 includes a CPU and a memory for executing arithmetic processing. The information processing means 2 includes a process for compressing image data obtained from the image taking means 1 and converting it into an image file, and an image file storage means 3. Image processing is performed, such as processing for decompressing a recorded image file and capturing of photographing data input from the photographing unit 1 based on detection information from the user operation receiving unit 6. Further, when recording the image file in the image file storage unit 3, the shooting information of the shooting data is recorded in the shooting information storage unit 7, or the browsing history is recorded in the browsing history information storage unit 8 corresponding to the image file. . The information processing unit 2 includes a search processing unit 2a that searches for a desired image file from a plurality of image files stored in the image file storage unit 3.

  The image file storage unit 3 is configured by, for example, a flash memory that is a non-volatile memory, and stores the image file output from the information processing unit 2. The position detection unit 4 detects the current position of the mobile device 10 using GPS (Global Positioning System) or the like. The date and time detection means 5 detects the current date and time. The user operation receiving unit 6 detects a button operation of the portable device by the user and inputs detection information to the information processing unit 2. The shooting information storage unit 7 has a function of storing shooting information corresponding to an image file when the shot image is stored in the image file storage unit 3. Similarly to the image file storage unit 3, the shooting information storage unit 7 Consists of memory and the like. Note that the shooting information is date / time information detected by the date / time detection means 5 or shooting date / time information or shooting position information in which position information detected by the position detection means 4 is associated with shooting. The current position detected by the position detector 4 and the current date detected by the date detector 5 constitute current information.

  The browsing history information storage unit 8 has a function of storing browsing history information of an image file corresponding to the image file, and is configured by a flash memory or the like, similar to the image file storage unit 3 and the shooting information storage unit 7. The The browsing history information is browsing date information and browsing position information in which date information detected by the date detection unit 5 and positional information detected by the position detection unit 4 are associated with the browsing history. The image display means 9 has a function of displaying an image as a GUI generated by the information processing means 2 and an image file, and is configured by an LCD or the like.

<Shooting operation>
Next, the operation will be described. First, based on FIG. 2, the process flow regarding the imaging operation in the portable device 10 will be described. First, in step 101, the user operates a button on the mobile device 10. The information processing means 2 activates the photographing means 1 based on the detection information output from the user operation receiving means 6 so that the portable device 10 can be photographed. Next, in step 102, the user performs a shooting operation. The information processing means 2 operates the photographing means 1 based on the detection information output from the user operation receiving means 6, performs photographing, and causes the image display means 9 to display photographing data. After shooting, if the user confirms the image data displayed on the image display means 9 and decides to record this image data, the processing of steps 103 and 104 is performed. That is, in step 103, the information processing means 2 acquires the current position obtained from the position detection means 4 as shooting position information, and acquires the current date and time obtained from the date and time detection means 5 as shooting date information. Next, in step 104, the photographic data is converted into an image file and stored in the image file storage unit 3, and the photographic information in which the photographic position information, the shooting date / time information and the image data are associated is stored in the photographic unit information storage unit 7. To do.

  Through the above operation, the image data captured by the portable device 10 is converted into an image file and then stored in the image file storage unit 3. Further, shooting information associated with the stored image file is stored in the shooting information storage unit 7. Accordingly, all image files shot by the portable device 10 and stored in the portable device 10 have shooting information of shooting position information and shooting date / time information.

  FIG. 3 is an image diagram of an image file database in the portable device 10 and shows a state in which information of a plurality of image files is registered in the image file database. As shown in FIG. 3, the registration record 401 includes an image file name, file attributes, shooting date / time of shooting data before being converted into an image file, shooting position, browsing date / time, browsing position, browsing count (1), (2 ).

  The number of files registered in the registration record is 3, the attribute of the image file with the file name “AAAA” is JPEG, the shooting date and time is 10:54 on April 11, 2004, the past browsing count is 3, and the browsing timing is You can see that it is between July and September. On the other hand, since the image file with the file name “AAAC” is immediately after shooting, the shooting date / time information and shooting position information are registered, but the number of times of browsing is zero, and the browsing date / time and browsing position are blank. Yes. In addition, each item, for example, an image file is stored in the image file storage unit 3, shooting information on the shooting date and time and a shooting position is stored in the shooting information storage unit 7, and the browsing count and browsing history information on the browsing position are It is stored in the browsing history information storage means 8. In FIG. 3, the browsing count (1) is set as time information in units of March, and the browsing count (2) is set as position information in units of 1 degree.

<Browse operation 1>
Next, based on FIG. 4, a processing flow related to a browsing operation when browsing an image file stored in the mobile device 10 will be described. Note that the image file browsing method in FIG. 4 is a state in which the number of image files stored in the image file storage unit 3 is small, and is the same method as that of Patent Document 1 described in the background art. The search using the browsing position is not performed. In this case, thumbnail list display for displaying about four reduced image files at a time on one screen of the image display means 9 is performed, each image file is confirmed from this list display screen, and a desired image is selected.

  First, in step 201, the user operates a button on the portable device 10 to display a thumbnail list of image files on the image display unit 9. In step 202, the information processing means 2 has a predetermined size capable of displaying a plurality of image files stored in the image file storage means 3 on the image display means 9 based on the detection information output from the user operation receiving means 6. The thumbnail list is displayed on the image display means 9. When the desired image file is not displayed, the user further performs an operation of displaying a new image file as a thumbnail list, and the information processing unit 2 displays the image file on the image display unit 9 based on the operation. If the desired image file is confirmed, the user performs an operation of selecting the desired image file in step 202. Based on the detection information output from the user operation receiving unit 6, the information processing unit 2 expands and displays the selected image file on the image display unit 9 to a size that can be displayed on one screen. Further, the information processing means 2 starts a timer (not shown) installed in the mobile device 10 and measures the time from the start of display of the selected image file.

  When ending the display of the image file on the image display means 9, the user performs a button operation to end the display of the image file in step 203. Based on the detection information output from the user operation receiving means 6, the information processing means 2 ends the display of the image file on the image display means 9 and stops the measurement by the timer in step 204. In step 205, the information processing means 2 determines whether or not the time when the image file is displayed on the image display means 9 exceeds a predetermined standard, for example, whether it is 1 minute or more. If the display time exceeds a certain standard, it is determined that browsing is significant for the user, and in step 206, the current position is acquired from the position detection means 4 and used as browsing position information. In step 207, the information processing means 2 registers the browsing position information acquired in step 206 in the image file database, and further increments the browsing count by one. Note that registration in the image file database is actually processing for registering browsing history information in the browsing history information storage unit 8. If the display time does not satisfy a certain standard, it is determined that the display image is not the image desired by the user, and the process ends without performing registration in the browsing history. Note that the date / time information obtained from the date / time detection means in step 206 may be acquired as browsing date / time information and registered in the image file database in step 207.

  FIG. 5 is a diagram showing a state where the image file having the file name “AAAC” registered in the image file database shown in FIG. 3 is browsed and registration of the browsing history information is completed. When the state of the registration record 501 in FIG. 5 is compared with the state of the registration record 401 in FIG. 3, the browsing date and time and the browsing position browsing count of the registration record 501 are registered, and the browsing history information is updated.

<Browse operation 2>
Next, another processing flow related to the browsing operation of the image file stored in the portable device 10 different from the processing flow shown in FIG. 3 will be described based on FIG. In FIG. 6, the number of image files stored in the portable device 10 increases, and the screen is updated many times even when the thumbnail list display described in the processing flow of FIG. 4 cannot be displayed or when the thumbnail list is displayed. A case where the user cannot find a desired image file without this will be described. In the processing flow of FIG. 6, a search using the current position, shooting position, and browsing position is performed.

  First, in step 301, the user operates the button of the mobile device 10 to display the menu list shown in FIG. 7A on the image display means 9, and then displays the user interface shown in FIG. 7B. Further, the user selects “Search” from the interface of FIG. 7B to display the search screen shown in FIG. Next, in step 302, the information processing means 2 determines whether or not the current position input from the position detection means 4 is already registered in the search item, that is, whether or not the current position can be used as the search item. to decide. If the current position can be used as a search item, the information processing unit 2 acquires current position information input from the position detection unit 4 in step 303. After that, the user checks “Condition 1” 701 in order to activate the search item to be input below on the search screen, then selects the search first item 702, and searches from the current position, browsing position, and imaging position. Determine the item. Further, the search second item 703 is selected, and the search item is determined from the current position, the browsing position, and the imaging position. The position that can be selected in the second search item 703 is a position different from the position determined in the first search item 703. Finally, the search third item 704 is selected, and a search condition is determined as to whether the search first item 702 and the search second item 703 are complete match, neighborhood match, or mismatch. In step 304, the search processing means 2a in the information processing means 2 searches the image file database according to the search items determined by such a procedure.

  If it is determined in step 302 that the current position cannot be used as a search item, the items used for the search in step 304 are a shooting position and a browsing position.

  By the way, the shooting position and the current position are uniquely determined, but there are a plurality of browsing positions in an image file browsed a plurality of times. Accordingly, in step 304, when there are a plurality of registered image files, the search processing means 2a searches to preferentially search, for example, an image file having a large number of browsing times. In step 305, the information processing means 2 rearranges so that image files with a large number of browsing times are displayed preferentially. Finally, a list of searched image files is displayed on the image display means 9. The processing after the image file list display in step 306 is the same as that after step 201 shown in FIG.

  In this way, the search method for preferentially searching for image files with a large number of browsing times and the display method for displaying image files with a high number of browsing times preferentially using the past browsing history effectively is a user's preference. Enables accurate search along. Therefore, a desired image file can be searched quickly and easily.

  That is, as shown in FIG. 4, the image file with the file name “AAAA” has three browsing histories, and “AAAB” has only one browsing history. In such a state, first, the search may be performed from “AAAA”. In addition, when a search is performed and both of them meet the search condition, “AAAA” may be preferentially displayed. Furthermore, when both have a plurality of browsing histories, image files with a large number of browsing histories may be searched and displayed with priority. In addition, when there are a plurality of image files having a browsing history that matches the search condition, an image file with a large total number of browsing histories may be preferentially displayed. You may display preferentially.

  Further, in the rearrangement of the search results in step 305, the image files having position information close to the search conditions in step 304 may be preferentially arranged, and rearrangement is performed from both the number of browsing histories and the position information. Also good.

  In the third search item 704 in step 304, it is possible to perform a search with a certain degree of ambiguity by making it possible to set a neighborhood match of almost a match in addition to a perfect match, and an effective search. Results can be obtained. Therefore, it is possible to easily search for a desired image file even when image files are not managed in the folder or the file name is not changed.

  As described above, in the mobile device 10 according to the present embodiment, the image file is searched using at least two of the three pieces of information of the shooting position, the viewing position, and the current position. Image files can be found.

<Browsing history information>
Here, the advantage when the search is performed using the browsing history information will be described with reference to FIG. In FIG. 9, the vertical axis represents the relationship between the current position and the browsing position. In the drawing, the upper side indicates that the current position and the browsing position are close, and the lower side indicates that the current position and the browsing position are far from each other. The horizontal axis represents the relationship between the current position and the shooting position. In the drawing, the right side indicates that the current position and the shooting position are close to each other, and the left side indicates that the current position and the shooting position are far from each other. Therefore, the image file stored in the image file storage means 3 can be distributed on the space constituted by these two axes.

  Note that the image file in the upper right area 1301 in the figure has a close relationship between the current position, the shooting position, and the viewing position, and the image file in the upper left area 1302 has the current position and the viewing position close, but the current position The position is far from the shooting position. The image file in the lower right area 1303 is close to the current position and the shooting position, but the current position is far from the viewing position, and the image file in the lower left area 1304 is also far from the three.

  In general, when a user wants to browse a certain image file, a certain amount of information such as a shooting location of the target image file or a location shown to a friend or the like is often recognized. From this approximate memory, it is possible to specify a shooting position and a browsing position and perform a search.

  Although the shooting position is not stored, but the browsing position is stored, for example, the shooting time of the image file to be browsed is much earlier than the current time, so the shooting position cannot be recalled. Suppose you are browsing. In this case, if the browsing situation or the like is remembered, the image file can be searched from the browsing position and the current position using the memory. Furthermore, if the search condition is set so that the file with the latest update history is searched and displayed with priority, the search and display can be performed more quickly and easily.

  A specific situation is assumed below. For example, consider a case where a grandfather or grandmother shows a grandchild image file taken at home when a child is brought home during summer vacation. In this case, since the current position and the shooting position are separated, if the search is performed with the first search item 702 as “current position”, the second search item 703 as “shooting position”, and the third search item 704 as “mismatch”. It becomes possible to select a desired image file. Thereafter, when this image file is browsed, the browsing history information associated with the image file is stored in the browsing history information storage unit 8. At this time, the browsed image file is in a relationship in which the current position and the shooting position are far away, and the current position and the browsing position are in agreement. Therefore, this image file is distributed in the area 1302 of FIG.

  Next, let us consider a case where the relative who came to the homecoming home is shown the image file browsed earlier. In this case, since the current position matches the browsing position, the first search item 702 is “current position”, the second search item 703 is “viewing position”, and the third search item 704 is “match” or “substantially match”. When the search is performed, a desired image file can be selected.

  The search may be performed by setting the first search item 702 as “browsing position”, the second search item 703 as “photographing position”, and the third search item 704 as “mismatch”. The search may be performed by setting the second search item 703 as “shooting position” and the third search item 704 as “mismatch”. However, since browsing is performed sooner than shooting, it is easier for the user to set the search item more intuitively by using “viewing position” than “shooting position” as the search item. A quick search can be performed. That is, since “browsing” is always an action later in time than “shooting”, the user is likely to remember the browsing action. The present invention is also characterized in that image files can be searched using browsing history information in consideration of such human characteristics.

  Further, consider a case in which this image file is shown to a friend after returning home. In this case, the current position and the shooting position coincide with each other, and the current position and the viewing position are far away. Therefore, this image file is distributed in the area 1303 of FIG. In order to search for this image file, the search may be performed by setting the search first item 702 as “current position”, the search second item 703 as “viewing position”, and the search third item 704 as “mismatch”. The search may be performed by setting one item 702 as “browsing position”, second search item 703 as “photographing position”, and third search item 704 as “mismatch”. Alternatively, the search may be performed by setting the first search item 702 as “current position”, the second search item 703 as “shooting position”, and the third search item 704 as “match” or “substantially match”. However, as described above, the use of “browsing position” rather than “shooting position” as a search item enables easy and quick search.

  Next, consider a case where an image file of a landscape photographed at a travel destination and an image file browsed at the travel destination is viewed at home. In this case, the current position and the shooting position are far from each other, and the current position and the viewing position are also far from each other. Therefore, this image file is distributed in the area 1304 in FIG. In order to search for this image file, the search may be performed by setting the search first item 702 as “current position”, the search second item 703 as “viewing position”, and the search third item 704 as “mismatch”. The search may be performed with one item 702 as “browsing position”, second search item 703 as “shooting position”, and third search item 704 as “match” or “substantially match”. The search may be performed by setting the first search item 702 as “current position”, the second search item 703 as “shooting position”, and the third search item 704 as “mismatch”.

  Also, consider a case where an image file of a landscape taken at a travel destination and an image file viewed at home are shown to a friend living near the home. In this case, the current position and the shooting position are far from each other, and the current position and the viewing position are close to each other. Therefore, this image file is distributed in the area 1302 of FIG. To search for this image file, the search may be performed by setting the first search item 702 as “current position”, the second search item 703 as “viewing position”, and the third search item 704 as “substantially match”. The search may be performed by setting the first item 702 as “browsing position”, the second search item 703 as “photographing position”, and the third search item 704 as “mismatch”. The search may be performed by setting the first search item 702 as “current position”, the second search item 703 as “shooting position”, and the third search item 704 as “mismatch”.

  In addition to the travel, the mobile device 10 may be used in business. For example, consider a case where a user who is currently working in the company tries to search for an image file that has been shot on a business trip and has been viewed in the company so far. In this case, the current position and the shooting position are far from each other, and the current position and the viewing position are close to each other. Therefore, this image file is distributed in the area 1302 of FIG. To search for this image file, the search may be performed by setting the first search item 702 as “current position”, the second search item 703 as “viewing position”, and the third search item 704 as “substantially match”. The search may be performed by setting the first item 702 as “browsing position”, the second search item 703 as “photographing position”, and the third search item 704 as “mismatch”.

  As described above, the shooting position of the image file is assumed to be various places such as a home, a place to go, a travel destination, and a business trip destination. According to the mobile device 10 of the present embodiment, the image file is roughly arranged. It is possible to search for an image file using a new search item “browsing history information” by using a new memory. As a result, a quick and easy search can be performed without requiring strict information, and the number of search items increases, so that an accurate search according to the user's intention can be performed.

  In the present embodiment, the image file storage unit 3, the photographing information storage unit 7, and the browsing history information storage unit 8 are different from each other. You may comprise by the information storage means and the image file storage means 3 which consist of the storage means 7 and the browsing history information storage means 8.

  Further, the position detection means 4 and the date detection means 5 have been described as different configurations. However, since the information detected from both detection means is current information, the position detection means 4 and the date detection means 5 are configured integrally. And it is good also as a detection means.

Embodiment 2. FIG.
In the present embodiment, a portable device capable of inputting search items using a map in the search processing flow described in the first embodiment will be described.

  FIG. 10 shows a search screen in the present embodiment. In FIG. 10, it is possible to specify a position together with the current position in the search first item 802. When the user selects position designation in the search first item 802, a position designation screen shown in FIG. 11A is displayed. The user operates the buttons of the mobile device 10 to move the cursor 901 on the map and specify the position. In this case, information input by position designation is input from the user operation receiving means 6 to the information processing means 2, and the result is reflected on the map displayed on the image display means 9. Therefore, the user operation receiving means 6 has a function as information input means.

  If the user designates a position on the position designation screen shown in FIG. 11A, a more detailed map as shown in FIG. 11B may be displayed. This makes it possible to specify more detailed positions. Note that when position designation is selected in the first search item 802, the position that can be selected in the second search item 703 is a shooting position or a browsing position.

  This makes it possible to effectively search for images taken and viewed at any location, and to search for an accurate image file in accordance with the user's intention. Note that the number of position designation screens may be three or more, and the larger the number, the more detailed position designation becomes possible and a user-friendly position designation method.

Embodiment 3 FIG.
In this embodiment, a portable device capable of searching for an image file using date and time information will be described.

  FIG. 12 shows an image file search processing flow in the present embodiment. First, in step 1001, the user operates the button of the mobile device 10 to display the list shown in FIG. 7A on the image display means 9, and then displays the user interface shown in FIG. 7B. Further, the user selects “Search” from the interface of FIG. 7B to display the search screen shown in FIG. After that, the user checks “Condition 1” 1101 in order to activate the search item to be input below on the search screen, and then selects the search first item 1102 on the search screen, and displays the current date, browsing date, and imaging. The search item is determined from the date and time and the date specification. Further, the search second item 1103 is selected, and the search item is determined from the current date, browsing date, and imaging date. Note that the date and time that can be selected in the second search item 1103 is an item that is different from the date and time determined in the first search item 1102. Finally, the search third item 1104 is selected, and a search condition is determined as to whether the search first item 1102 and the search second item 1103 are complete match, proximity match, or mismatch. In step 1004, the search processing means 2a in the information processing means 2 searches the image file database according to the search items determined by such a procedure.

  Steps 1002 and 1003 have the same processing contents as steps 305 and 306 in FIG. 6, respectively. When the date and time designation is set in the first search item 1102, the date and time are input numerically by operating the buttons of the mobile device 10.

  Thus, in this embodiment, the search can be performed using the date / time information. Accordingly, the user can freely set a search based on the date and time when photographing and browsing are performed, and an accurate search according to the user's intention can be performed.

  In the date and time search process, a search based on grouping, such as a search by the same time zone, a search by the same day of the week, or a search by the same season, may be performed. By providing time information in this way, it becomes possible to search even under more ambiguous conditions, and the probability of obtaining a desired image file is improved.

  Also in this embodiment, the date and time input by the user may be used as a search item. In this case, an image file search condition is set based on either the shooting date / time or the browsing date / time and the date / time specified by the user.
