(First embodiment)
Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, an example in which an image is displayed using GPS (Global Positioning System) information recorded in an image file will be described. Specifically, a process for continuously displaying images captured at a location within a certain range from the reference position using GPS information recorded in a certain image file as a reference position will be described.

First, creation of an image file used in the present embodiment will be described. FIG. 1 is a block diagram illustrating a configuration example of an imaging apparatus 100 that performs recording by adding GPS information and shooting date / time information to captured image data.
In FIG. 1, reference numeral 1 denotes a control unit that controls the entire imaging apparatus 100, and reference numeral 2 denotes a GPS unit that receives a signal from an artificial satellite and generates GPS information. Reference numeral 3 denotes a time measuring unit that generates current date and time information, and reference numeral 4 denotes an imaging unit including a lens, a CMOS sensor, and the like.

  Reference numeral 5 denotes an image encoding unit that encodes image data input from the imaging unit 4 as still image data, and reference numeral 6 denotes a file creation unit that converts the encoded still image data into a file in accordance with the Exif standard. Reference numeral 7 denotes a recording medium for recording the still image file created by the file creation unit 6.

  When recording of an image file is instructed by a user from an operation unit (not shown), the control unit 1 controls the imaging unit 4 to perform a shooting process. When image data is input from the imaging unit 4 to the image encoding unit 5 by the imaging process, the control unit 1 controls the image encoding unit 5. Then, according to parameters such as image quality and image size set in the image capturing apparatus 100, for example, still image encoding processing such as compression is performed by the JPEG method.

  When the still image encoding process is completed, the compressed image data is input to the file creation unit 6. The control unit 1 acquires GPS information from the GPS unit 2, acquires current date and time information from the time measuring unit 3, and outputs them to the file creation unit 6. The control unit 1 also outputs to the file creation unit 6 camera control parameters such as an aperture value and shutter speed when the imaging unit 4 is controlled, and parameters such as image quality and image size set in the imaging device 100. .

  The file creation unit 6 writes (sets) the information input from the control unit 1 in the Exif header, and writes the compressed image data in the image data area of the Exif file. Then, an image file according to the Exif standard is created and recorded on the recording medium 7. When an image file is recorded on the recording medium 7, a file name according to the DCF standard is assigned and recorded under the control of the control unit 1.

  As a result of the above processing, GPS information and shooting date / time information are recorded in the created image file, and file names with sequential numbers such as “IMG — 0001.JPG” and “IMG — 0002.JPG” are assigned in the shooting order. . The I / F 8 is for transferring data to a display device 9 such as a monitor of a personal computer (PC), for example.

FIG. 2 is a flowchart illustrating an example of an operation procedure for determining a display order when a plurality of images including images taken at different places are displayed in succession in the present embodiment. Each step shown in FIG. 2 is performed under the control of the control unit 1.
First, in step S101 of FIG. 2, the file entry of the image file to be displayed is stored in an array “file”. For example, the file entry of the recorded Exif file is stored in a directory on the hard disk specified by the user.

  In step S102, the total number of file entries stored in step S101 is set in a variable num. In step S103, the file entries stored in step S101 are sorted in order of date and time of file creation or file name.

  Next, in step S104, the variable next is initialized to zero. Here, the value obtained by subtracting 1 from the variable next represents the index number of the file array whose display order is determined. Immediately after the sorting is completed in step S103, next-1 = -1, so that there is no corresponding index. For this reason, the image to be displayed first is not determined, but in this embodiment, as a result of sorting in step S103, the image file of the file entry stored in file [0] is displayed first. Treat as an image.

  In step S105 and subsequent steps, processing for determining the actual display order is executed. Next, in step S105, the control unit 1 functions as position information acquisition means, acquires GPS information recorded in the image file of file [next], and sets it in the variable GPS_1. Here, the variable GPS_1 is a variable for setting position information used as a reference position for discriminating images close to the shooting location.

  In step S106, next + 1 is set to the variable cmp. Here, the variable cmp is a variable for setting the index number of the image file to be compared with the reference position. In step S107, the value of the variable next is incremented by one. With this process, the display order of the image file with the previous index number is determined. When the sorting in step S103 is completed and step S107 is executed for the first time, next = 1, the file entry of file [0] is confirmed after sorting, and this image file is treated as the first displayed image. become.

  Next, in step S108, the GPS information recorded in the image file of file [cmp] is set in the variable GPS_2. Here, the variable GPS_2 is a variable for setting position information to be compared with the reference position set in the variable GPS_1.

  Next, in step S109, the control unit 1 functions as a determination unit, compares the position information set in the variable GPS_1 and the variable GPS_2, and the shooting location of the file [cmp] is within a certain range from the reference position. Determine if it exists. The determination as to whether or not the distance is within a certain range is performed, for example, by determining whether or not the distance between the two points of the variable GPS_1 and the variable GPS_2 is equal to or less than a certain distance. The distance between the two points can be calculated by the “Hubeni distance calculation formula” shown in the following equation 1 using the respective latitude / longitude information.

  As a result of the determination in step S109, when the shooting location of file [cmp] does not exist within a certain range with respect to the reference position, the process proceeds to step S112. On the other hand, if the result of determination in step S109 is within a certain range, the process proceeds to step S110. In step S110, the control unit 1 functions as an extraction unit, shifts the array elements from file [next] to file [cmp-1] one by one to the back of the array, and changes the contents of file [cmp] to file [cmp]. Set to next]. A table for explaining the operation of step S110 is shown in Table 1 below.

  As shown in Table 1, before the shift process is performed in step S110, each file [] array stores image files in the order described in the "before shift" column. When the shift process is performed, as described in the column “after shift”, an image file of file [cmp] before the shift process is set in file [next]. Then, array elements from file [next] to file [cmp−1] before the shift process are respectively shifted and set from file [next + 1] to file [cmp].

FIG. 3 is a flowchart showing an example of the operation procedure of the shift process in step S110 of FIG.
First, in step S21, the contents of file [cmp] are temporarily saved in the variable file_temp. Here, the variable file_temp is for temporarily saving when performing shift processing. In step S22, the loop control variable i is initialized with the value set in the variable cmp.

Next, in step S23, file [i], which is the previous array element, is set in file [i], and the array element is shifted by one. In step S24, the value of the variable i is decreased by 1. Next, in step S25, it is determined whether the value of i is equal to or less than the value of next. That is, it is determined whether or not the shift processing of all the array elements from file [next] to file [cmp−1] has been completed.

  If the result of this determination is that the shift process has not ended, the process returns to step S23, and the next array element is shifted. On the other hand, if the result of determination in step S25 is that shift processing has been completed, processing proceeds to step S26 where the value of file_temp that was temporarily saved in step S21 is set in file [next].

  After the file [] array shift process is performed as described above, the value of the variable next is incremented by 1 in step S111. By this process, the display order of the image file in which the position information is set in the variable GPS_2, in which the file entry is replaced in step S110, is determined.

  Next, in step S112, the value of the variable cmp is increased by 1, and the index of the image file to be compared with the reference position is changed. In step S113, it is determined whether or not the value of the variable cmp matches the value of the variable num. If the result of this determination is that they do not match, the comparison with the variable GPS_1 as the reference position has not been completed, and there is an image file whose display order is undetermined. continue.

  On the other hand, if the value of the variable cmp matches the value of the variable num as a result of the determination in step S113, the comparison with the variable GPS_1 that is the reference position has not been completed, and there is no image file whose display order is undetermined. Therefore, the process proceeds to the next step S114. In step S114, it is determined whether or not the value of the variable next is equal to or greater than the value obtained by subtracting 1 from the variable num.

  As a result of this determination, if the variable next matches num-1, the display order of the image files up to the index number num-2 is fixed. That is, the display order of the image file of file [num-1] is not uniquely determined. However, since the display order of other image files is fixed, the image file of file [num-1] is inevitably determined as the image file to be displayed last. Therefore, if the variable next matches num, the display order of the image files with all index numbers is fixed.

  If the determination result in step S114 is Yes, the display order of all the image files is fixed as described above, and the process proceeds to step S115. Then, the control unit 1 functions as a display control unit, and causes the display device 9 connected to the I / F 8 to display images in the order of storage based on the final file entry information stored in the file [] array. On the other hand, as a result of the determination in step S114, if the value of the variable next is less than the value obtained by subtracting 1 from the variable num, the process returns to step S105. Then, among the image files whose display order is uncertain, the GPS information of the image file with the smallest index number is used as a reference position, and the same comparison process is continued to determine the display order.

  As described above, according to the present embodiment, among a plurality of images taken at a plurality of different places, it is possible to continuously display related images that exist within a certain range from the reference position, A display form without a sense of incongruity can be provided. Thereby, when a plurality of images taken at different places are displayed at the same time, an image browsing environment suitable for the user can be provided.

(Second Embodiment)
In this embodiment, as in the first embodiment, images taken at a location within a certain range from the reference position are continuously displayed, and images taken at a position close to the reference position are sequentially displayed. Processing for performing display will be described. Note that the configuration of the imaging apparatus according to the present embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

  FIG. 4 is a flowchart showing an example of an operation procedure for determining the display order in the present embodiment. Each step shown in FIG. 4 is performed under the control of the control unit 1. In FIG. 4, steps having the same numbers as those in FIG. 2 are the same processes as the steps described in the first embodiment, and thus description thereof is omitted in this embodiment.

  After sorting the file entries in the order of the date and time when the image file was created in step S103 or in the order of the name of the image file, the variable next_key is initialized to 0 in step S201. Here, the variable next_key is an index number of a file array in which an image file having reference position information for determining the display order is stored.

  Next, in step S104, the variable next is initialized to zero. In this embodiment, the value obtained by subtracting 1 from the variable next represents the index number of the file array whose display order is tentatively determined.

  And after finishing the process of step S105 from step S105, it progresses to step S202. In step S202, the distance from the reference position is set to the set variable dist [next] for file [next], which is an image file determined to be a shooting location within a certain range from the reference position. . Next, in step S111, the value of the variable next is incremented by 1, and the display order of the image files up to file [next-1] is provisionally determined. Next, in step S112, the value of the variable cmp is increased by 1, and the index of the image file to be compared with the reference position is changed.

  Next, in step S113, it is determined whether or not the value of the variable cmp matches the value of the variable num. If the result of this determination is that they do not match, there is an image file whose display order is unconfirmed that has not been compared with the variable GPS_1 as the reference position, so the process returns to step S108 and the same comparison processing is continued. To do.

  On the other hand, if the value of the variable cmp matches the value of the variable num as a result of the determination in step S113, there is no image file whose display order is unconfirmed that has not been compared with the variable GPS_1 as the reference position. Accordingly, the process proceeds to step S203, and the display order of images taken within a certain range from the reference position is determined.

  As a result of the processing from step S105 to step S113, all the image files stored in file [next_key + 1] to file [next-1] are image files shot within a certain range from the reference position. Therefore, the process of rearranging these image files in order from the closest to the reference position is performed in step S203. Specifically, the display is sorted by sorting the file [] array elements in ascending order of the dist [] element corresponding to each file [] array element, and the display order is determined. When the process of step S203 is performed, the display order from file [0] to file [next-1] is fixed.

  Next, in step S204, the next value is set to the variable next_key in order to set the image file with the smallest index number as the next reference position among the image files whose display order is not fixed. In step S114, it is determined whether or not the value of the variable next is equal to or larger than a value obtained by subtracting 1 from the variable num. As in the first embodiment, if the display order is not fixed, the process returns to step S105 to determine the display order. If the display order is fixed, the image is displayed in step S115.

  As described above, according to the present embodiment, it is possible to continuously display images captured at a location within a certain range from the reference position, and sequentially display images captured at positions close to the reference position. it can.

(Third embodiment)
In the present embodiment, an example will be described in which an image captured by a specific imaging device is displayed with priority. Note that the configuration of the imaging apparatus according to the present embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

  FIG. 5 is a flowchart showing an example of an operation procedure for determining the display order in the present embodiment. Each step shown in FIG. 5 is performed under the control of the control unit 1. In FIG. 5, steps having the same numbers as those in FIG. 4 are the same processes as the steps described in the second embodiment, and thus description thereof is omitted in this embodiment.

  After sorting the file entries in the order of the date and time when the image file was created in step S103 or in the order of the name of the file, in step S301, the control unit 1 functions as a device information acquisition unit and acquires information on the photographing device that created the image file. To do. Then, the control unit 1 functions as a device rearranging unit, and sorts the elements of the sorted file [] array again based on the information of the photographing device that created the image file. When sorting is performed in order of date and time when the image file was created in step S103, the file [] array stores the image file in the order of the photographing device that created the image file as shown in Table 2 below. The image files of the respective photographing devices are stored in order of date and time (time series) when the image files are created.

FIG. 6 is a flowchart showing an example of a detailed operation procedure of the sorting process in step S301 of FIG.
First, in step S401 in FIG. 6, a variable i for controlling the processing loop is initialized to zero. In step S402, a variable j for controlling the processing loop is initialized.

  Next, in step S403, the photographing device information is acquired from the image file set in file [j-1] and set in the variable dev1. In step S404, the photographing device information is acquired from the image file set in file [j] and set in the variable dev2. In the Exif standard, the manufacturer name, model name, and author information of the photographing device can be recorded as ASCII character strings, and these character strings can be used as photographing device information by being acquired from an image file and combined.

  Next, in step S405, the imaging device information acquired in steps S403 and S404 is compared. If the variable dev1 has a smaller value than the variable dev2 as a result of this comparison, the process proceeds to step S406, and the element of file [j-1] and the element of file [j] are exchanged. On the other hand, as a result of the comparison in step S405, if the variable dev2 has a smaller value than the variable dev1, the process proceeds to step S407.

  Steps S407 to S410 are processes for loop control of the sort process. In step S407, j is decreased by 1. In step S408, it is determined whether j> i. If it is determined that j> i, the process returns to step S403; otherwise, the process proceeds to step S409. Next, in step S409, i is incremented by 1, and in step S410, it is determined whether i <num−1. If i <num-1 as a result of this determination, the process returns to step S402; otherwise, the process ends.

  As described above, when all the processes are completed, the sorting process is completed. The flowchart shown in FIG. 6 is an example of an algorithm generally called bubble sort, but other sort algorithms can be used. The processing after performing the sort processing based on the imaging device information in step S301 of FIG. 5 is the same as the processing after step S201 of the second embodiment.

  As described above, in the present embodiment, the top part of the file [] array is preferentially used for the image file used as the reference position for comparing the shooting positions. For this reason, by performing the processing of the present embodiment, an image file shot with a specific shooting device can be preferentially used as a reference position, and the display order is also an image shot with a specific shooting device. Files can be prioritized.

(Fourth embodiment)
In the present embodiment, an example will be described in which an image captured by a specific imaging device selected by the user is displayed with priority. Note that the configuration of the imaging apparatus according to the present embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

  FIG. 7 is a flowchart illustrating an example of an operation procedure for determining the display order in the present embodiment. Each step shown in FIG. 7 is performed under the control of the control unit 1. In FIG. 7, steps having the same numbers as those in FIG. 5 are the same processes as the steps described in the third embodiment, and thus description thereof is omitted in this embodiment.

  In step S301, the elements of the file [] array are sorted again based on the information of the photographing device that created the image file. In step S501, a list of photographing device information is created.

Here, the processing content of step S501 will be described in detail with reference to FIG. FIG. 8 is a flowchart illustrating an example of a processing procedure for creating a list of photographing apparatus information in step S501 of FIG.
First, in step S601, the photographing device information of the first image file in the file [] array is acquired and set in the first element of the device array. Next, in step S602, the variable i is initialized to 0. Here, the variable i is a variable indicating an index number for setting the photographing device information in the array device [].

  Next, in step S603, a variable j for loop control is initialized. In step S604, it is determined whether or not the shooting device information of the image file of file [j] matches the shooting device information set in device [i]. If the result of this determination is that they do not match, the process advances to step S605 to set the image capturing device information of the image of file [j] in device [i + 1]. In step S606, the value of i is incremented by one.

  On the other hand, if the result of determination in step S604 is a match, processing proceeds to step S607. Next, in step S607, the value of j is incremented by one. In step S608, it is determined whether the value of j matches the value of num. That is, it is determined whether or not all file [] array elements have been checked. If the check is not completed as a result of this determination, the process returns to step S604, and the next array element is checked. On the other hand, if the result of determination in step S <b> 608 is that the check has ended, the process ends. When the processing shown in the flowchart of FIG. 8 is completed, information on all the photographing devices that created the image file to be displayed is set in the device [] array.

  Next, in step S502 of FIG. 7, for example, the display device 9 such as a PC monitor displays the list of imaging device information created in step S501 via the I / F 8. When certain photographing device information is selected by the user via the operation unit (not shown) from the displayed photographing device information, in step S503, the control unit 1 functions as a selection unit, and the selected photographing device is set in the variable sel_dev. Set information.

  Next, in step S504, based on the imaging device information set in the variable sel_dev, the image file created by the imaging device having the selected imaging device information is rearranged so as to be set at the head of the file [] array. I do.

The processing content of step S504 will be described in detail with reference to FIG. FIG. 9 is a flowchart illustrating an example of a processing procedure for rearranging the array elements in step S504 of FIG.
First, in step S701, the variable i is initialized to 0. Here, the variable i is a variable for indicating an index number used for setting an image file corresponding to the value set in the variable sel_dev in step S503 in FIG. 7 in the file [] array.

  In step S702, a loop control variable j is initialized to zero. In step S703, the shooting device information of the image file of file [j] is set in the variable dev. Next, in step S704, it is determined whether or not the value set in the variable dev is the same as the value set in the variable sel_dev in step S503 in FIG. If the result of this determination is not the same, the process proceeds to step S707.

  On the other hand, if the result of determination in step S704 is the same, the process proceeds to step S705, where the array elements from file [i + 1] to file [j-1] are shifted one by one to the back of the array, and file [j] Is set to file [i]. In step S706, the value of i is incremented by one.

  Next, in step S707, the value of j is incremented by one. In step S708, it is determined whether the value of j matches the value of num. That is, it is determined whether or not the processing of all file [] array elements has been completed. If the result of this determination is that processing for all array elements has not been completed, processing returns to step S703 and processing continues. On the other hand, as a result of the determination in step S708, if the processing for all the array elements is completed, the processing is ended as it is. The processing after performing the sorting process based on the photographing device information in step S504 in FIG. 7 is the same as the processing after step S201 in the third embodiment.

  As described above, in the present embodiment, the top part of the file [] array is preferentially used for the image file used as the reference position for comparing the shooting positions. For this reason, by performing the processing of the present embodiment, an image file shot by a specific shooting device selected by the user can be preferentially used as a reference position. The display order can also be given priority to image files shot by the selected specific shooting device.

  In the present embodiment, the example in which the user selects the imaging device in step S502 and step S503 has been described. On the other hand, when all the image files are recorded on a recording medium of a certain photographing device and display processing is performed by the photographing device, the processing in step S502 is omitted, and in step S503, information on the photographing device is changed to a variable sel_dev. Set to. Thereby, it is possible to give priority to the image file photographed with the photographing device.

(Fifth embodiment)
In the first embodiment, an example has been described in which images taken at a location within a certain range are continuously displayed. In the present embodiment, an example will be described in which images that are shot at a place within a certain range and that have a predetermined difference in shooting time within a predetermined time range are continuously displayed. Note that the configuration of the imaging apparatus according to the present embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

  FIG. 10 is a flowchart illustrating an example of an operation procedure for determining the display order in the present embodiment. Each step shown in FIG. 10 is performed under the control of the control unit 1. In FIG. 10, steps having the same numbers as those in FIG. 2 are the same processes as those described in the first embodiment, and thus description thereof is omitted in this embodiment.

  After the GPS information recorded in the file [next] image file is set in the variable GPS_1 in step S105, the shooting date / time information of the file [next] image file serving as the reference position is set in the variable DT1 in step S901. In step S108, the GPS information recorded in the image file of file [cmp] is set in the variable GPS_2, and in step S902, the shooting date / time information of the image file in file [cmp] is set in the variable DT2.

  Next, in step S903, the variable DT1 is compared with the variable DT2, and it is determined whether or not a predetermined difference in photographing time is within a predetermined time. If the result of this determination is that the time is within the predetermined time, the processing from the next step S109 is performed, and if it is outside the predetermined time, the process proceeds to step S112 without determining the shooting location.

  By performing the processing as described above, it is possible to continuously display only highly relevant images that are close to the shooting location and close in time.
