Description

  The present invention relates to a terminal with a display function, and is particularly suitable for use in a mobile terminal such as a mobile phone or a PDA (Personal Digital Assistant).

  In general, a mobile terminal such as a mobile phone is provided with a liquid crystal display, and various information is displayed on the display surface of the liquid crystal display. If the display surface is large, a large amount of information (such as documents) can be displayed at once, or a television image can be projected greatly. However, on the other hand, when the display surface becomes large, the size of the device itself becomes large, which is easily disturbed when it is carried.

  In view of such circumstances, a mobile phone that has two display surfaces and is capable of switching between a state in which these display surfaces overlap in the front-rear direction and a state in which they are aligned in the horizontal direction has been considered. Such a cellular phone is disclosed in Patent Document 1, for example. According to this mobile phone, if the two display surfaces are overlapped, the device main body becomes small, so that it is difficult to get in the way when being carried. On the other hand, if the two display surfaces are arranged in use, an image can be displayed on a large screen.

The liquid crystal displays 400 and 500 display an image corresponding to the image signal.

  Now, when the second cabinet 2 is closed and in the first display state, an image is displayed on the first display surface 11.

  FIG. 4 is a diagram showing a display example of an initial screen (function mode selection screen) displayed on the first display surface 11 in the first display state in the mobile phone according to the present embodiment.

  In the central portion of the first display surface 11, eleven types of mode keys M 1 such as “TV”, “Mail”, and “Map” are arranged as main displays. When the user presses a desired mode key M1 on the screen, a function mode corresponding to the mode key M1 is executed. On the top of the first display surface 11, an antenna mark M2 indicating a reception state, a mail mark M3 indicating that a mail has been received, and a remaining capacity mark M4 indicating the remaining battery level are arranged as sub-displays.

  In this initial screen, if the user presses the “data” mode key M1, for example, the mode shifts to the data display mode. In this data display mode, the user can confirm an image (such as a photographic image) stored in the memory 600 by performing a predetermined operation. The user may use this mode for the purpose of simply viewing these images. On the other hand, this mode may be used for the purpose of selecting a desired image from these images. In this case, the selected image can be used as a wallpaper image on the standby screen of the mobile phone, transferred to another device such as a personal computer, or attached to an e-mail and sent to another person.

  FIG. 5 is a flowchart for explaining screen display control in the data display mode in the mobile phone according to the present embodiment. 6 to 10 are diagrams showing screen display examples when screen display control is performed in the data display mode in the mobile phone according to the present embodiment.

  As described above, when the “data” mode key M1 is pressed, the display control unit 110 reads the image data of the reduced image M5 from the memory 600 and displays an image signal for displaying the reduced image M5 on the liquid crystal display. 400. As a result, a list screen in which a plurality of reduced images M5 are arranged is displayed on the first display surface 11 (S1: see FIG. 6). In the list screen, the file name of each image is displayed below the reduced image M5. A scroll operation unit M6 for sending a list screen is displayed at the right end of the screen.

  The reduced image M5 is a sample (index) of an original image (hereinafter referred to as “original image”) stored in the memory 600. The image data of the reduced image M5 is generated by performing thumbnail processing on the image data of the original image, and is stored in the memory 600.

As described above, when selecting a desired image, the user can select a desired image by sequentially viewing the reduced images M5 displayed on the list screen. However, the images stored in the memory 600 may include a plurality of similar images such as a continuous photograph. When a desired image (for example, a photograph with the best reflection) is selected from these similar images, the size of the reduced image M5 is too small, and it is difficult to make a detailed comparison between these images. .

  Thus, in such a case, the user selects one of the plurality of reduced images M5 to be compared and touches it with a finger or the like. When one file (for example, “009.jpg”) is selected, the reduced image M5 is changed to a display form different from that of the other reduced images M5, such as a thicker frame of the image. Thus, after selecting a desired file, the user performs a switching operation to bring the mobile phone to the second display state.

  When the user performs a switching operation and enters the second display state, the ON signal from the open sensor 25 is input to the CPU 100 as described above. The display control unit 110 determines that a switching operation has been performed based on the ON signal (S2: YES). Note that it may be configured that the switching operation is performed when the signal from the closing sensor 24 is turned OFF, or when the ON signal of the closing sensor 24 disappears and the ON signal of the opening sensor 25 exists, the switching operation is performed. It is good also as a structure which judges that it was made.

  Next, the display control unit 110 determines whether a file corresponding to the reduced image M5 is selected by the user by touching one of the reduced images M5 displayed in the first display state. (S3). If it is determined that a file is selected (S3: YES), the display control unit 110 executes the comparison screen mode by the following operations from step S4 to step S10.

  That is, the display control unit 110 reads the image data of the original image of the selected file from the memory 600, and generates an image signal of the intermediate image M7 corresponding thereto. Further, the display control unit 110 reads the image data of the original images of the files before and after the selected file from the memory 600, and generates image signals of the intermediate image M8 and the intermediate image M9. Then, the image signals of these intermediate images M7, M8, M9 are sent to the liquid crystal display 500, and the intermediate images M7, M8, M9 are displayed on the second display surface 21 (S4: see FIG. 7).

  As shown in FIG. 7, on the second display surface 21, an intermediate image M7 of the selected file (for example, “009.jpg”) is displayed at the center of the screen. The intermediate image M8 of the previous file (for example, “008.jpg”) is displayed on the left side of the intermediate image M7, and the intermediate image M9 of the subsequent file (for example, “010.jpg”) is the intermediate image. Displayed on the right side of M7. These three intermediate images M7, M8, and M9 are displayed as large as possible within a range that can be accommodated on the second display surface 21. In particular, the center intermediate image M7 is displayed slightly larger than the left and right intermediate images M8 and M9. In addition, the file names of the respective images are displayed below the intermediate images M7, M8, and M9.

  Thus, three successive intermediate images M7, M8, and M9 that are several steps larger than the reduced image M5 are displayed on the second display surface 21. Thereby, the user can compare these intermediate images M7, M8, and M9 in detail and select a desired image.

  Now, on the screen on which the three intermediate images M7, M8, M9 are displayed on the second display surface 21 (hereinafter referred to as “comparison screen”), if the center intermediate image M7 is touched by the user, the display The control unit 110 determines that the central file has been selected (S5: YES), reads the image data of the original image of the selected file from the memory 600, and generates an image signal of the enlarged image M10. And the image signal of this enlarged image M10 is sent to the liquid crystal display 500, and the enlarged image M10 is displayed on the 2nd display surface 21 (S6: refer FIG. 8). The enlarged image M10 is displayed with the maximum size that can be accommodated on the second display surface 21. In this way, the user can confirm the image of the selected file in more detail.

  The display control unit 110 may be configured to display an enlarged image on the first display surface 11 instead of the second display surface 21. The display control unit 110 may be configured to display an enlarged image on the large screen formed by the first display surface 11 and the second display surface 21 with the maximum size that can be accommodated on the large screen.

  On the other hand, on the comparison screen, when either the left or right intermediate image M8 or M9 is touched by the user instead of the central intermediate image M7, the display control unit 110 determines that the left or right file has been selected. (S7: YES), the same process as in step S4 is performed to display the intermediate image M7 ′ of the selected file at the center of the second display surface 21, and the intermediate image M8 ′ of the file before and after the file. , M9 ′ are displayed on the left and right of the intermediate image M7 ′ (S8). For example, in FIG. 7, when a file “010.jpg” is selected, an intermediate image M7 ′ of this file is displayed in the center of the screen as shown in FIG. 9, and “009.jpg” and “011” are displayed. Intermediate images M8 'and M9' of the file ".jpg" are displayed on the left and right. In this way, the user can scroll the comparison screen on the second display surface 21 back and forth, and the image between the three intermediate images M7 ′, M8 ′, and M9 ′ newly displayed by scrolling. Can be compared.

  Further, on the comparison screen, the file (for example, “008.jpg” to “010.jpg”) currently displayed on the list screen is separated from the file (for example, “001.jpg” to “001.jpg”). It is conceivable that an intermediate image “003.jpg”) is to be displayed. In such a case, it is possible to scroll the comparison screen until the intermediate image of the file appears on the second display surface 21 by the scroll operation described above, but this takes a long time.

  Therefore, in such a case, the user touches the reduced image M5 of a desired file (for example, “002.jpg”) on the list screen on the first display surface 11. When the display control unit 110 determines that a file has been selected on the list screen (S9: YES), the display control unit 110 performs the same operation as in step S4. As a result, three images, the intermediate image of the selected file and the intermediate images of the preceding and subsequent files, are displayed on the second display surface 21 (S10). In this way, the user can promptly display an intermediate image of a file at a position away from the currently displayed file on the second display 21 surface.

  By the way, unless a desired image is selected from similar images such as continuous photographs, the user does not need to compare the images.

  Therefore, in such a case, the user performs a switching operation to the second display state without selecting a file in a state where the list screen of the reduced image M5 is displayed in the first display state (see FIG. 6). Do. If it does in this way, in previous step S3, display control part 110 will judge that a file is not selected (S3: NO), and will perform list screen mode by operation of the following steps S11 to S13.

  That is, the display control unit 110 reads out the image data of the reduced image M5 following the reduced image M5 displayed on the first display surface 11 from the memory 600, and outputs an image signal for displaying the reduced image M5 to the liquid crystal display 500. Send it out. Thereby, the list screen by the reduced image M5 following the 1st display surface 11 is displayed on the 2nd display surface 21 (S11: refer FIG. 10). In this case, the list screen on the first display surface 11 and the list screen on the second display surface 21 are integrated. Therefore, when the scroll operation unit M6 is operated, the integrated list screen is scrolled.

  Next, when the user selects a desired file on the list screens on both the first display surface 11 and the second display surface 21 (S12: YES), the display control unit 110 performs the same process as in step S6. I do. Thereby, the enlarged image M10 of the selected file is displayed on the second display surface 21 (S13). In this case, the screen form is the same as that shown in FIG. In this way, the user can view a desired image in a large size.

  As described above, according to the present embodiment, the comparison screen mode is executed in the second display state in which the first display surface 11 and the second display surface 21 face the outside. In this comparison screen mode, intermediate images M7, M8, and M9 having a size larger than the reduced image M5 are selected for the file selected by the reduced image M5 on the first display surface 11 and the files before and after the file. 2 is displayed on the display surface 21. Thereby, the user can compare these intermediate images in detail on the second display surface 21. Therefore, even if the images stored in the mobile phone include similar images such as continuous photos, a desired image can be easily selected from the plurality of images.

  Further, according to the present embodiment, the user can further select a file on the comparison screen on which the intermediate images M7, M8, and M9 are displayed, and can display an enlarged image M10 of the file. Therefore, the user can confirm the image in more detail by enlarging the desired image as necessary.

  Furthermore, according to the present embodiment, the comparison screen is scrolled back and forth according to the scroll operation by the user, and a new intermediate image is displayed. Therefore, the user can compare the images while sequentially sending the intermediate images, which improves usability.

  Furthermore, according to the present embodiment, when a file is newly selected from the list screen on the first display surface 11, an intermediate image between the file and the previous and subsequent files is newly displayed on the second display surface 21. Therefore, when displaying an intermediate image of a file at a position away from the currently displayed file on the second display 21 surface, the user can quickly display these intermediate images, which improves usability. .

  Furthermore, according to the present embodiment, the comparison screen mode is executed by a predetermined transition operation of selecting a file before performing the switching operation to the second display state, and if the predetermined transition operation is not performed, List screen mode is executed. Therefore, when the user does not need to compare similar images, if the user does not perform a predetermined transition operation, the user simply selects the reduced image M5 on the list screen, and the enlarged image M10 corresponding to the reduced image M5. Can see. Therefore, a desired image can be quickly confirmed with a larger size.

  Furthermore, according to the present embodiment, the predetermined transition operation to the comparison screen mode is an operation of selecting a file before performing the switching operation to the second display state. Migration operation can be performed without providing.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and the embodiment of the present invention can be variously modified as appropriate. For example, it can be changed as follows.

  FIG. 11 is a flowchart for explaining a modified example of the screen display control in the data display mode. FIG. 4A shows a flowchart of the first modification, and FIG. 2B shows a flowchart of the second modification.

  In the first modification, instead of the operation in step S3 in the above embodiment, the operations in steps S14 to S16 are performed. That is, in the configuration of the modification example 1, when the transition to the second display state is made, the list screen shown in FIG. 10 is displayed on both the first display surface 11 and the second display surface 21. When a desired file is selected from this state, the display mode is switched to the display form shown in FIG. 9 or FIG. Which of the display forms in FIG. 9 or FIG. 10 is switched to is set in advance by the user. Here, the mode for switching to the display mode of FIG. 9 is referred to as “comparison mode”, and the mode for switching to the display mode of FIG. These modes are set by, for example, operating the “SET” mode key M1 on the initial screen shown in FIG.

  If the display control unit 110 determines in step S2 that the switching operation to the second display state has been performed, the display control unit 110 determines whether or not the display mode after the switching is set to the comparison mode (S14). If it is determined that the comparison mode is set, the display control unit 110 performs the same processing as in step S11 described above, and displays a list screen of reduced images M5 following the first display surface 11 on the second display surface 21. It is displayed (S15). As a result, a screen similar to FIG. 10 is displayed.

  Further, in this state, when a user-desired file is selected from the list screens on both the first display surface 11 and the second display surface 21 (S16: YES), the display control unit 110 performs the operation of step S4. Do. As a result, as shown in FIG. 7, three images, the intermediate image M7 of the selected file and the intermediate images M8 and M9 of the files before and after the selected file, are displayed on the second display surface 21.

  On the other hand, if the display control unit 110 determines in step S14 that the comparison mode is not set (enlargement mode is set), the display control unit 110 proceeds to the process of step S11 in FIG. That is, a list screen of reduced images M5 following the first display surface 11 is displayed on the second display surface 21 (S11). As a result, a screen similar to FIG. 10 is displayed. Further, in this state, when the user selects a desired file from the list screens on both the first display surface 11 and the second display surface 21 (S12: YES), the display control unit 110 performs the operation in step S13. I do. As a result, an enlarged image M10 of the selected file is displayed as shown in FIG.

  Note that the display control unit 110 does not display the list screen on the second display surface 21 by the operation in step S15, but instead displays a message screen for prompting file selection as shown in FIG. Such an operation may be performed.

  Next, in Modification 2, the operations of Step S17 and Step S18 are added between the operation of Step S4 and the operation of Step S5 in the above embodiment. That is, in the above embodiment, only the reduced images of the still image file are arranged on the list screen. However, in the configuration of the second modification, the moving image file and the still image file are stored in the memory 600. The reduced images of these files are mixedly arranged on the list screen. In such a configuration, when the display screen mode is shifted to the comparison screen mode, the display control unit 110 determines whether a moving image is included in the selected file and the preceding and succeeding files (S17). If a moving image is included (S17: YES), the display control unit 110 sends an image signal to the liquid crystal display 500 to reproduce the moving image. Thereby, in the screen form shown in FIG. 7, among the three intermediate images of the comparison screen displayed on the second display surface 21, the intermediate image of the moving image file is displayed in the moving image state. With such a configuration, the user can easily confirm that the original image is a moving image when viewing the intermediate image. Moreover, when there are a plurality of intermediate images of moving images, the moving images can be easily compared with each other.

  Separately from the list screen for still images only, a list screen for only videos can be displayed. When the comparison screen mode is executed from the list screen for movies, the intermediate image is displayed in the state of the movie. Also good.

  Further, in the above embodiment, when one file is selected on the list screen, an intermediate image M7 of this file and intermediate images M8 and M9 of files adjacent thereto are displayed. This is because it is assumed that similar images such as continuous photographs are often stored with continuous file names and are often arranged adjacent to each other on the list screen. However, when the file name is changed or the like, as shown in FIG. 13, similar images may be arranged at distant positions on the list screen. Therefore, in order to cope with such a case, the following configuration may be adopted.

<Configuration example 1>
In this configuration example, image data is stored in the memory 600 in association with time information, and when an image is enlarged and displayed, images whose time information approaches each other are selected and displayed as similar images. Here, it is desirable that the time information is in units of seconds or smaller in order to increase the accuracy of selection. For example, when time information is in units of minutes, there are many images having the same time (minute) as time information, and there is a high possibility that dissimilar images are included in these images. In order to avoid this, it is desirable to set the time information in units of seconds or shorter.

  When shooting is performed with the camera module 13 in the configuration example of FIG. 3, time information at the start of shooting is acquired from the internal clock, and image data is stored in the memory 600 in association with this time information. In this case, the time information is in units of seconds, preferably shorter. In this case, when images that are close in time are selected, these images are usually similar to each other.

  However, the memory 600 can also include image data acquired by communication from other devices. Also in this case, time information (shooting time, etc.) is usually associated with the image data, but this time information is a unit longer than the second unit (for example, only the date) due to the setting of other devices. In some cases. Therefore, in this case, when images that are close in time are selected, a large number of images are selected, and among these, images that are not similar to each other may be included. In this case, for example, it is necessary to further screen a large number of selected images. As a selection criterion at that time, for example, a file name (file number) or the like that approaches a file name (file number) can be selected as in the above embodiment. Alternatively, when position information by GPS (Global Positioning System) is added to each image, it is also possible to select an image that the position information approaches.

  In this way, when selecting an image based on time information, the display control unit 110 selects the desired file, for example, the file “009.jpg” from the list screen shown in FIG. Instead of the operation of step S4 in the comparison screen mode executed in the embodiment, the following operation is executed.

  In other words, the display control unit 110 reads two files from the memory 600 in the order closest to the shooting date and time of the selected file, and displays the intermediate images M8 and M9 of these two files together with the intermediate image M7 of the selected file. It is displayed on the display surface 21. When there are three or more files having similar shooting dates and times, two files are selected based on the file name (file number) and position information as described above. Thus, as shown in FIG. 14, the second display surface 21 has a selected image and a similar image (for example, “008.jpg”, “kid 1.jpg”, regardless of the arrangement on the list screen). ]) Is displayed.

  It should be noted that a file in which a certain amount of time has elapsed with respect to the shooting time of the selected file is considered not to have been shot at the same time, and is not considered similar to the selected file. Therefore, when two files that are close to the shooting time of the selected file are extracted, if any of them has a shooting time longer than a predetermined time, an intermediate image of the file is not displayed. It can also be.

<Configuration example 2>
As described above, a similar image can be selected based on the shooting position data (shooting position data). In this case, the shooting position data is stored in the memory 600 in association with the image data. A GPS function is added to the configuration shown in FIG. That is, a GPS antenna and a GPS communication processing unit are further added to the configuration shown in FIG. The GPS communication processing unit communicates with a GPS satellite via a GPS antenna and acquires position information. The position information acquired at the time of shooting is stored in the memory 600 together with the image data as shooting position data.

  In this case, when a desired file is selected from the list screen shown in FIG. 13, the display control unit 110 reads out two files from the memory 600 in order of closeness to the shooting position of the selected file. The intermediate images M8 and M9 of the file are displayed on the second display surface 21 together with the intermediate image M7 of the selected file (see FIG. 14).

  Depending on the position detection accuracy of the GPS communication processing unit, a slight difference in position may not be determined, and the shooting positions of a plurality of files may be the same. In such a case, the file may be extracted by taking the shooting time information in addition to the shooting position information.

  Further, in the above embodiment and the above configuration example, when a desired file is selected from the list screen, an intermediate image of a file that seems to be similar to the image of the file, such as a moving image or a still image, is displayed. Is displayed. However, for example, when a moving image and a still image are mixed in similar images, the user may want to compare only a similar still image or only a similar moving image. Therefore, a configuration may be adopted in which images that are considered to be similar are extracted from those having the same file format as the selected file.

  In addition, in the above-described embodiment, when the center intermediate image M7 is touched on the comparison screen, the enlarged image M10 is displayed, and when the left and right intermediate images M8 and M9 are touched, the intermediate image is forward and backward. It is configured to be scrolled. However, the present invention is not limited to this. For example, even if any of the three intermediate images M7, M8, and M9 is touched, an enlarged image of the touched file may be displayed. Further, in such a configuration, a scroll operation unit may be arranged in the comparison screen, and the intermediate image may be scrolled back and forth by the operation of the scroll operation unit.

  In the above-described embodiment, three intermediate images are displayed on the comparison screen. However, the present invention is not limited to this, and two or four or more intermediate images may be displayed. However, the larger the number of intermediate images, the smaller the size. Therefore, the number of intermediate images needs to be set so as not to become too small in relation to the size of the display surface.

  In the above-described embodiment, it is described that images that are assumed to be similar are extracted. However, the extracted images are not necessarily similar, and the file name, time, and position described in the above-described embodiment are used. It is only necessary to extract an image that satisfies a preset similarity criterion.

In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
