Description

  The present invention relates to an information processing apparatus, an information processing method, and a program. More specifically, for example, the present invention relates to an information processing apparatus, an information processing method, and a program for performing processing for displaying a shooting position of a camera shot image on a map.

  Some imaging devices such as video cameras and still cameras in recent years have a position acquisition function such as GPS (Global Positioning System). Such a camera acquires position information by GPS or the like when shooting a still image or a moving image, and uses the acquired position information as attribute information (metadata) of a captured image along with an image such as a flash memory or various kinds of images. Record on a disc.

  The position information recorded on the medium together with the shot image is used as information for indicating the shooting position, for example. Specifically, it is applied to display processing of thumbnails (reduced images) of captured images in conjunction with map display.

  With such display data, the user can confirm the shooting point of the shot image on the map. Various proposals have already been made for the process of recording position information indicating the shooting position in the shot image and the display processing configuration of the map and thumbnail image.

  For example, a general method is to determine the range and scale of the map to be displayed based on the shooting position information of the image to be displayed together with the map. However, the setting of the map range and the setting of the scale when displaying a plurality of images together on the map are complicated. As a prior art disclosing a method for determining a map display mode when there are a large number of display images, for example, there are the following prior arts.

  Japanese Patent Application Laid-Open No. 2006-148514 discloses a method of automatically determining a display range of a map when a plurality of captured images are displayed on a map. The outline of the method of Patent Document 1 is as follows. First, information such as shooting latitude and longitude or shooting range, moving speed, and video playback speed is acquired from the metadata (still images and videos) included in the playlist set as the playback display list of the shot images. To do. Next, by analyzing these pieces of information, a range of a map that can include all images to be displayed is calculated, and a range obtained by adding a margin to the calculated range is determined as a display range of the map.

  According to the configuration described in Patent Document 1, playlists are automatically classified by applying information such as date / time, shooting location, and photographer. Further, when the shooting positions of a plurality of images included in the playlist are greatly separated, the setting is made to have a plurality of map ranges.

  Patent Document 2 (Japanese Patent Laid-Open No. 2006-185242) calculates a distance between position information of a plurality of images, applies the distance information to group images, and displays a map in units of groups. A configuration for determining the range is disclosed.

  As described above, various proposals have been made for a display processing method of a map corresponding to an image having position information. However, in many of these conventional methods, first, position information set in correspondence with an image to be displayed is acquired, and this acquired data is applied to determine the display range and scale of the map. It is the structure which displays a map according to it.

However, actually, there are cases where position information is not recorded in attribute information (metadata) of an image that the user intends to display. For example, when shooting is performed in a building, indoors, or underground mall, position information cannot be acquired by GPS, and position information corresponding to a captured image is not recorded. In such a case, with the conventional configuration, map data cannot be displayed, and the map display process may stop. A similar situation occurs when trying to display a map in a situation where no image is taken, such as when a new camera is purchased or a new memory is installed.

1. 1. Configuration example of information processing apparatus 2. Basic operation of information processing apparatus 3. Display map determination process for the display unit Other configuration examples of information processing devices

[1. Configuration example of information processing apparatus]
The information processing apparatus of the present invention can be configured by, for example, an imaging device (camera) that captures a still image or a moving image, a PC, or a server. Hereinafter, the configuration and processing of an imaging apparatus (camera) will be described as an embodiment of the information processing apparatus of the present invention.

  FIG. 1 shows a configuration example of an imaging apparatus which is an embodiment of an information processing apparatus of the present invention. The imaging device 100 acquires at least one of still image data and moving image data by imaging processing. The photographed image data is recorded on the medium as content data. The medium is configured by a disk such as a flash memory, HD, DVD, or the like.

  As shown in FIG. 1, the imaging apparatus 100 includes a control unit 101, a position information acquisition unit 102, a RAM 103, a ROM 104, an imaging unit 105, an image processing unit 106, a display unit 107, a storage unit 108, an address / data bus 109, and an address. A data bus processing unit 110 is included.

  The control unit 101 performs overall control of various processes executed in the imaging apparatus 100, such as a shooting process, a position information acquisition process, and a display process of a shot image and map information. These processing control execution programs are recorded in the ROM 104 or the storage unit 108, and the control unit 101 executes various processes according to the programs.

  The position information acquisition unit 102 is configured using, for example, a GPS (Global Positioning System) module. The GPS module includes an antenna unit that receives GPS radio waves, a signal conversion unit for received radio waves, a calculation unit for position information, and the like. The position information acquisition unit 102 acquires position information indicating the current position where the imaging apparatus 100 exists.

  The RAM 103 is used as a working memory for temporarily storing image signals and data, for example. The RAM 103 is provided with a frame buffer and work buffer area. Note that the frame buffer is an area for storing an image signal read when the display unit 107 displays an image. The work buffer is an area used for forming a display image using, for example, map data or image data.

  The ROM 104 is a program that executes processing control such as various processes executed in the imaging apparatus 100 as described above, such as a shooting process, a position information acquisition process, and a display process of a shot image and map information, and parameters applied to the program. Information is recorded.

  The imaging unit 105 includes an optical system block, an imaging element, a signal processing circuit, and the like. Specifically, it is configured by a lens, an image sensor such as a CCD (Charge Coupled Devices), a focus / exposure control unit (AF / AE), and the like. An optical image of a subject is formed on an image pickup surface such as a CCD of an image pickup device, and an electric signal photoelectrically converted from the CCD is output. The imaging device is not limited to a CCD, and for example, a CMOS (Complementary Metal Oxide Semiconductor) type image sensor can be used. The image sensor performs photoelectric conversion, generates an image signal corresponding to the optical image, and outputs the image signal to the image processing unit 106.

  The image processing unit 106 converts the image signal supplied from the imaging unit 105 into a digital signal and performs various signal processing. For example, development processing, color correction, resolution conversion, compression / decompression processing, and the like are performed as necessary. This signal processing result data is recorded in the storage unit 108.

  Note that the data recorded in the storage unit 108 includes position information (longitude / latitude information, etc.) and date / time information acquired by the position information acquisition unit 102 at the image capturing timing under the control of the control unit 101. Attribute information (metadata) is added and recorded.

  The storage unit 108 records these attribute information (metadata) along with the image data. The storage unit 108 is configured using a recording medium such as a nonvolatile memory, an optical disk, and a hard disk device. The attribute information recorded together with the image in the storage unit 108 includes various information such as date information and face detection information at the time of photographing in addition to position information. The storage unit 108 stores map data for performing map display.

  The storage unit 108 and the RAM 103 further record operation information executed by the user, that is, operation history information. The recording and use configuration of this operation history information will be described later.

  The display unit 107 is configured by using a liquid crystal display element such as an LCD, for example, and displays image data, map data, and the like. The image data displayed on the display unit 107 is a current image captured by the imaging unit 105 or a captured image stored in the storage unit 108. Further, the display unit 107 displays a map indicating the current position or a map indicating the shooting position of the captured image.

  The display unit 107 displays various menus for selecting the display data or controlling the camera such as mode setting. The display unit 107 has a function of an input unit as a touch panel, for example, and can control the camera such as selection of display data or mode setting by a user operation. When a touch operation is performed, the touch panel generates an operation position signal indicating the panel coordinates of the operation position and supplies the operation position signal to the control unit 101. In the following description, it is assumed that the display unit 107 has an input unit function as a touch panel.

  The control unit 101 is connected to each unit via an address / data bus 109. Data transfer control via the address / data bus 109 is performed by the address / data bus processing unit 110. As described above, the control unit 101 controls various processes executed in the imaging apparatus 100 by executing a program stored in the ROM 104, for example.

  For example, the control unit 101 performs display control of data output to the display unit 107. For example, display of a captured image designated by the user or position information set as image attribute information is read, and map data corresponding to the read position information is acquired from the storage unit 108 and displayed. In addition, the control unit 101 performs processing for displaying the image and the map together on the display unit 107.

  When displaying a map on the display unit 107, the control unit 101 determines the range, scale, and center position of the map to be displayed. The map determined by the display map determination process is output to the display unit 107.

  Note that the imaging apparatus 100 configures an image file from image data, attribute information, and the like according to an Exif (Exchangeable image file format) standard that is general standard data, for example, and stores the image file in the storage unit 108. Further, a process for storing in the information storage unit 108 is performed by applying a file system corresponding to, for example, a DCF (Design rule for Camera File System) standard that facilitates exchange of image files and the like.

  FIG. 2 is a diagram illustrating a directory configuration example related to image data recorded in the storage unit 108 by the information processing apparatus 100 using a file system. An index file 202 for managing image files is set directly under the top folder 201 as an upper directory. Further, image files 203-1 to 203-n including image data, attribute information, thumbnail data, and the like are stored below the index file 202. The folder name of the top folder 201 and the file names of the image files 203-1 to 203-n may be specified by the user, or the names may be automatically determined.

  The index file 202 stores management information for easily searching for desired image data and attribute information. The index file 202 is a file in which the file name and / or identification ID and attribute information of the image files 203-1 to 203-n stored in the top folder 201 are associated with each other. The attribute information is, for example, information such as the shooting date / time and position information, the number of faces included in the captured image, and facial expressions.

  Therefore, the control unit 101 can easily search for a desired image file by using the information of the index file 202. When the index file 202 is not provided, a desired image file can be searched by reading necessary information from each image file.

  However, such attribute information is not necessarily included for all images. For example, when images are taken in an environment where the GPS function cannot be used, such as in a building, indoors, or underground mall, the position information acquisition unit 102 such as GPS cannot acquire position information at the shooting timing of these images. As a result, attribute information in which position information is not recorded is set in the captured image, and image data having no position information is stored in the storage unit 108.

[2. Basic operation of information processing device]
Next, the basic operation of the information processing apparatus will be described. FIG. 3 illustrates an example of a display screen displayed on the information processing apparatus, for example, the display unit 107 of the imaging apparatus 100 illustrated in FIG.

  When the operation starts in the imaging mode, the control unit 101 displays an imaging mode screen as shown in FIG. The control unit 101 causes the display unit 107 to display a camera image using the image signal generated by the imaging unit 105. Further, the control unit 101 provides button display of a current position button BTa and a playback button BTb on the camera image, for example.

The current position button BTa is a button for switching the display to a current position screen in which the current position of the imaging device 10 is shown on a map.
[Current position display mode] is started by operating this button.
The playback button BTb is a button for switching the display to a view selection screen that is a screen for selecting what type of playback is to be performed.
[Playback mode] is started by operating this button.
The playback mode has a plurality of modes as described below, and the user can select a playback mode to be executed from the plurality of playback modes.

When detecting a user operation on the current position button BTa, the control unit 101 switches the imaging mode screen to the current position screen shown in FIG.
The display screen shown in FIG. 3B is a display screen of [current position display mode].

  In the “current position display mode”, the control unit 101 acquires position information indicating the current position from the position information acquisition unit 102. Further, the control unit 101 acquires map data from the storage unit 108 based on the acquired position information, and generates a map having the current position as the center position of the map area of the display unit 107 based on the acquired map data. It is displayed on the display unit 107. Further, the control unit 101 provides a current position marker MKP indicating the current position on the generated map.

  When detecting a user operation on the playback button BTb, the control unit 101 switches the imaging mode screen to a view selection screen shown in FIG. The view selection screen shown in FIG. 3C is a start screen for [playback mode]. As shown in FIG. 3C, a button for selecting the type of playback mode is displayed on the view selection screen.

The reproduction mode includes the following plurality of modes, and the user can select an arbitrary mode.
(A) MAP: Display an image along with a map [Map index mode]
(B) Face: Select and display an image with a face detected [Face playback mode]
(C) FILMROLL: Displays a captured moving image as a still image at a fixed interval [film roll playback mode]

  For example, when the user operates the operation button [MAP] corresponding to [Map index mode] on the view selection screen shown in FIG. 3C, the control unit 101 displays the display on the display unit 107 in FIG. Switch to the map index mode display screen shown in.

  On the map index mode display screen, a map area ARa and a content selection area ARb are provided. The map area ARa is an area for displaying a map image GM, a content marker MKC, a selection marker MKS indicating the selected content, and the like. The content selection area ARb is an area for displaying a predetermined number of thumbnails of the image file stored in the storage unit 108.

  The control unit 101 determines the priority order of the image file stored in the storage unit 108 based on a predetermined attribute or an attribute desired by the user, and stores the thumbnails of the image file in the order of the determined priority order. Displayed in the selection area ARb. For example, as shown in FIG. 3D, when three thumbnails can be displayed in the content selection area ARb, the control unit 101 displays the thumbnail of the image file with the highest priority in the center area. . Also, thumbnails of the next highest priority image files are displayed in the lower area. Furthermore, the control unit 101 associates the thumbnail displayed in the content selection area ARb with the display of the map area ARa, and displays a map corresponding to the thumbnail displayed in the content selection area ARb.

  For example, the control unit 101 acquires position information from attribute information corresponding to the thumbnail displayed in the center area, and displays a map so that the position indicated by the acquired position information becomes the center position of the map area ARa. To do. Furthermore, the control unit 101 determines based on the attribute information whether image data generated by performing imaging within the range of the map displayed in the map area ARa is stored in the storage unit 108. Here, when image data generated by imaging within the range of the displayed map is stored, a content marker MKC is provided at the imaging position. Furthermore, when the map index mode display screen is displayed, the control unit 101 performs display control of a map or the like according to a user operation.

[3. Display map determination process for the display unit]
Next, display map determination processing for the display unit will be described as processing executed by the information processing apparatus of the present invention.

  As described above, the image pickup apparatus 100 shown in FIG. 1 which is the information processing apparatus of the present invention sets the position information acquired by the position information acquisition unit 102 at the time of image shooting as attribute information (metadata) of the shot image. And stored in the storage unit 108.

  When displaying the image stored in the storage unit together with the map, for example, when performing display in the map index mode shown in FIG. 3D, the position is determined from the attribute information associated with the image to be displayed. The information is read out and a map including the position determined by the position information is displayed.

  For example, when one image is designated as a display target, display of a map including the position obtained from the position information included in the attribute information set corresponding to the one image as a center is executed. When a plurality of images are designated as display targets, the map range and scale are determined so as to include a plurality of positions of the images, and the map is displayed on the display unit 107.

  Furthermore, in the information processing apparatus of the present invention, the position information is not included in the attribute information corresponding to the image specified as the display target, the display image is not specified, or the image is not stored in the storage unit The map to be displayed is determined according to a preset algorithm according to various situations. That is, the control unit 101 performs processing for determining the range, size, center, and the like of the display map according to the situation.

  FIG. 4 is a flowchart illustrating a sequence in which the control unit 101 of the information processing apparatus according to the present invention determines a display map. Note that the flow shown in FIG. 4 shows processing executed in the map display determination processing in the map index mode.

The process of each step of the flow shown in FIG. 4 will be described.
First, in step S <b> 101, the control unit 101 confirms whether there is user operation history information stored in, for example, the storage unit 108 or the RAM 103. As described above, the operation history information of the user is recorded in the storage unit 108 or the RAM 103. For example, information related to the map finally displayed on the display unit 107 in the map index mode is recorded in the storage unit 108 or the RAM 103 as operation history information. The storage unit 108 is a non-volatile memory, and the recorded operation history information is not deleted even when the power is turned off. The operation history information recorded in the storage unit 108 and the RAM 103 is information including the range of the map and the scale information displayed on the display unit 107 last.

The operation history information recorded in the storage unit 108 and the RAM 103 is sequentially updated according to the user operation, and only the latest information is stored as the operation history information. That is, the control unit 101 executes a process of sequentially updating the operation history information according to the map display, and obtains the latest display map display mode information from the operation history information in the process of determining a new map display mode. And use it. Although details will be described later, the operation history information is stored in each mode, for example,
[Map index mode] compatible operation history information,
[Current location display mode] compatible operation history information,
For example, it is individually recorded as operation history information corresponding to each mode.

  Therefore, the control unit 101 confirms the current setting mode, and confirms the presence / absence of operation history information according to the current setting mode. The flow shown in FIG. 4 is a flow executed in [map index mode], and in step S101, the control unit determines whether or not operation history information corresponding to [map index mode] exists in the storage unit 108 or the RAM 103. Check.

  If there is no operation history information corresponding to [map index mode] in the storage unit 108 or the RAM 103, the process proceeds to step S102, and if it exists, the process proceeds to step S121.

  First, a process when the operation history information corresponding to the [map index mode] does not exist in the storage unit 108 or the RAM 103 will be described. In this case, the process proceeds from step S101 to step S102. In step S102, the control unit 101 determines whether there is a display image.

  The determination process in step S102 is a determination process for determining whether there is an image based on a user's designation or an image determined by default. The image may be either a still image or a moving image.

  If the display image designation information is input by the user, the determination in step S102 is Yes. When there is no user designation, it is confirmed whether or not the identification information of the image finally displayed in the reproduction mode can be acquired. If it can be acquired, the image is selected as a display image. Also in this case, the determination in step S102 is Yes.

As described above, the image reproduction mode includes the following plurality of modes, and the user can perform image reproduction processing by selecting an arbitrary mode.
(A) MAP: Display an image along with a map [Map index mode]
(B) Face: Select and display an image with a face detected [Face playback mode]
(C) FILMROLL: Displays a captured moving image as a still image at a fixed interval [film roll playback mode]
The identification information of the image data reproduced in these reproduction modes is recorded in either the ROM 104 or the storage unit 108.

  In step S102, when the reproduction image is not designated by the user, it is confirmed whether or not the identification information of the image finally displayed in any one of the reproduction modes (a) to (c) can be acquired. . If it can be obtained, the image is selected as a display image.

When the user designation information is input or when the identification information of the final display image can be acquired, the determination in step S102 is Yes and the process proceeds to step S103.
On the other hand, if no user-specified information is input and the identification information of the final display image cannot be acquired, the determination in step S102 is No and the process proceeds to step S203.

  First, a process when the determination in step S102 is Yes, that is, when user-specified information is input or when identification information of the final display image can be acquired will be described. In this case, the process proceeds from step S102 to step S103.

  In step S103, the attribute information (metadata) of the selected display image is analyzed, and it is confirmed whether or not position information is recorded in the attribute information (metadata) of the display image.

  If position information is recorded in the attribute information (metadata) of the display image, the determination in step S103 is Yes and the process proceeds to step S201. In step S201, a default scale set in advance is applied, and a map set around the position corresponding to the position information recorded in the attribute information (metadata) of the display image is determined as the display map.

  On the other hand, if position information is not recorded in the attribute information (metadata) of the display image, the determination in step S103 is No and the process proceeds to step S202. In step S202, a default map having a preset default scale and range is determined as a display map. This map is, for example, a map determined in the initial setting, and is a map determined in the factory shipment stage.

  For example, the default map is determined in advance according to the model number of the information processing apparatus and the destination country, and is read and displayed according to a program stored in the apparatus. Specifically, for example, a map of the center of Tokyo is set as a default map when the device is for Japan, and a map of New York is set as a default map when the device is for the United States.

  A process when the determination in step S102 is No, that is, when there is no input of reproduction image designation information by the user and the identification information of the final display image cannot be acquired will be described. In this case, the process proceeds to step S203.

  In step S203, the same processing as in step S202 is performed. That is, a default map having a preset default scale and range is determined as a display map.

  Next, a process when the determination in step S101 is Yes, that is, when the user operation history information stored in the storage unit 108 or the RAM 103 can be acquired will be described. The flow shown in FIG. 4 is a flow executed in [map index mode], and in step S101, the control unit determines whether or not operation history information corresponding to [map index mode] exists in the storage unit 108 or the RAM 103. Check. If operation history information corresponding to [map index mode] exists in the storage unit 108 or the RAM 103, the determination in step S101 is Yes, and the process proceeds to step S121.

  Step S121 is the same process as the determination process of step S102. That is, the control unit determines the presence or absence of a display image. This is a process for determining whether or not there is an image based on user designation or an image determined by default. The image may be either a still image or a moving image.

When the designation information of the display image is input by the user, or when the identification information of the image finally displayed in the reproduction mode can be acquired, the determination in step S121 is Yes in these cases. In addition, as explained above, the playback mode
(A) MAP: Display an image along with a map [Map index mode]
(B) Face: Select and display an image with a face detected [Face playback mode]
(C) FILMROLL: Displays a captured moving image as a still image at a fixed interval [film roll playback mode]
All of these playback modes are included.

When the user designation information is input or when the identification information of the final display image can be acquired, the determination in step S121 is Yes and the process proceeds to step S122.
On the other hand, if no user-specified information is input and the identification information of the final display image cannot be acquired, the determination in step S121 is No and the process proceeds to step S204.

  First, a process when the determination in step S121 is Yes, that is, when user-specified information is input or when identification information of the final display image can be acquired will be described. In this case, the process proceeds from step S121 to step S122.

  In step S122, the attribute information (metadata) of the selected display image is analyzed, and it is confirmed whether or not position information is recorded in the attribute information (metadata) of the display image.

If position information is recorded in the attribute information (metadata) of the display image, the determination in step S122 is Yes and the process proceeds to step S206.
In step S206, the scale information of the previous display map is acquired from the operation history information, the ratio scale is applied, and the position corresponding to the position information recorded in the display image attribute information (metadata) is the center. The set map is determined as the display map.

On the other hand, if position information is not recorded in the attribute information (metadata) of the display image, the determination in step S122 is No, and in this case, the process proceeds to step S205.
In step S205, the scale and range of the previous display map are acquired from the operation history information, and a map having the acquired scale and range is determined as the display map.

  A process when the determination in step S121 is No, that is, when there is no input of reproduction image designation information by the user and the identification information of the final display image cannot be acquired will be described. In this case, the process proceeds to step S204.

  In step S204, the same processing as in step S205 is performed. That is, the scale and range of the previous display map are acquired from the operation history information, and the map having the acquired scale and range is determined as the display map.

  As described above, in the information processing apparatus of the present invention, even when the display image cannot be acquired or the position information is not recorded in the attribute information set corresponding to the display image, the information is displayed on the display unit 107. Will always display some kind of map.

The processing in the flow shown in FIG. 4 is performed in six steps S201 to S206.
However, the actual map display mode is
(A) Step S206,
(B) Steps S204, S205
(C) Steps S202 and S203
(D) Step S201
These are (A) to (D).

The display conditions and display modes of these four types of maps are summarized as shown in FIG. That is,
(A) Operation history [presence], display image [presence], position information [presence]: Map set centering on the scale and display image position of the previous display map (B1) Operation history [presence], display image [ [Yes], Location information [None]: Same map as previously displayed map scale / range (B2) Operation history [Yes], Display image [No], Location information [No]: Scale / range of previous display map Same map (C1) Operation history [none], display image [none], location information [none]: Default scale / range map (C2) Operation history [none], display image [present], location information [none]: Default scale / range map (D) Operation history [None], Display image [Yes], Position information [Yes]: Map set based on the default scale & position of display image The display map is determined as described above. It will be.

  In the process described with reference to FIG. 4, in steps S103 and S122, a process for verifying whether or not position information is recorded in the attribute information of the image to be displayed is performed. In these processing steps, if position information is not recorded in the attribute information, the process proceeds to step S202 or step S205, where default information or operation history information is set.

  However, for example, when a plurality of images are selected as display images, the attribute information of the plurality of images is verified in order, and if at least one piece of position information is recorded, the position information may be applied. Good. In this case, the determination in step S103 and step S122 is Yes, and the process in step S201 or step S206 is performed.

  Further, when position information is not recorded in all of the display image attribute information, for example, another photographed image within a preset time period, for example, a time range of 30 minutes, using date information included in the attribute information as a key. And whether or not the position information is recorded in the attribute information of the image extracted by the search may be verified. When position information is recorded in the attribute information of the search image, the position information may be used to execute the process of step S201 or step S206.

When this processing is performed, [position of display image] shown in step S201 and step S206 is replaced with [position of searched image]. That is,
In step S201, a map set with a default scale and a position corresponding to the searched image as a center is determined as a display map.
In step S206, a map set around the scale of the previous display map and the position corresponding to the searched image is determined as the display map.

  The display map determination process described with reference to FIGS. 4 and 5 is a process in the case where the “map index mode” in the reproduction mode is set as described above. The map display process is not limited to this [map index mode], but is also performed in [current position display mode] for displaying the current position.

  Even in the “current position display mode”, the position information acquisition unit 102 may or may not be able to acquire position information. In this case, the control unit 101 performs the following processing.

(1) When the position information acquisition unit 102 can acquire the position information The scale at the time of the previous map display is applied with the acquired position as the center. The scale at the time of the previous map display is the data at the time of the final display in [Current position display mode]. As described above, since the operation history information stored in the storage unit or the RAM is divided and recorded for each mode, the operation history information acquired in [Current position display mode] is the same as [Current position display]. Data at the time of final display in [Mode]. If the operation history information cannot be acquired, a preset scale is applied by default.

(2) When the position information acquisition unit 102 cannot acquire position information In this case, the same map data at the time of the final display in the same mode as the previous time, that is, [current position display mode], together with a message indicating that position information cannot be acquired. Display range and scale maps. When the operation history information cannot be acquired, a map with a scale and range set in advance by default is displayed together with a message that the position information cannot be acquired.

  As described above, the control unit 101 of the information processing apparatus according to the present invention performs a determination process on the display map mode for the display unit 107. For example, the control unit 101 determines a display map according to a program that defines processing according to the flow shown in FIG.

The storage unit 108 stores an image file 321, map data 322, and operation history information 323. The operation history information 323 is also stored in the RAM 103 shown in FIG.

  The operation information analysis unit 301 of the control unit 101 acquires and analyzes the operation history information 323 of the storage unit 108. This process is executed as the process of step S101 in the flow shown in FIG.

  The image selection unit 302 executes the processing of step S102 and step S121 of the flow shown in FIG. In other words, a process of selecting the selection information of the reproduction image of the user or the image corresponding to the final display image in the same mode from the image file 321 of the storage unit 108 is executed.

  The attribute information analysis unit 303 executes the processing of step S103 and step S122 of the flow shown in FIG. That is, the selection information of the reproduction image of the user or the attribute information corresponding to the image corresponding to the final display image in the same mode is analyzed. The image file 321 in the storage unit 108 is configured as an Exif file including image data and attribute information, and the attribute information analysis unit 303 acquires attribute information from these files and determines whether or not position information is included. If it is included, the position information is acquired.

  The output map determination unit 304 determines the mode of map data to be output to the display unit 107 according to the processing results of the operation information analysis unit 301, the image selection unit 302, and the attribute information analysis unit 303. Specifically, the scale and range are determined. A map in any one of steps S201 to S206 in the flow shown in FIG. 4 is determined as a display mode. According to the determined information, map data 322 in the storage unit 108 is acquired, and if necessary, the image processing unit 106 performs decoding, expansion processing, and the like, and outputs the result to the display unit 107.

  As described above, the operation history information 323 stored in the storage unit 108 is individually recorded as operation history information corresponding to each mode. The control unit 101 performs processing for storing the operation history information individually in the storage unit 108 according to the setting mode of the information processing apparatus, and corresponds to the same mode as the current setting mode when determining a new map display mode. The display mode is determined using the operation history information.

  A specific example will be described with reference to FIG. As shown in FIG. 7, map index mode compatible operation history information 401 and current position display mode compatible operation history information 402 are individually recorded in the storage unit 108. The operation history information is information including the scale and range information of the displayed map.

  The operation information analysis unit 301 of the control unit 101 confirms the current setting mode, and acquires operation history information corresponding to the current setting mode from the storage unit 108. The current setting mode information 421 can be executed by reading mode information recorded in the RAM 103, for example.
