Description

  The present invention provides a photographing apparatus comprising photographing means for acquiring an image by photographing, storage means for storing an image photographed by the photographing means, and display means for displaying an image stored in the storing means. About.

  In conventional photographing apparatuses, it has been emphasized how to manage a large number of stored photographs on the premise that all photographed photographs are preserved. In order to save many photos efficiently, the user is required to make a setting in advance, and the user needs to make a setting when changing the saving method. Since photos are managed using information set in advance by the user and supplementary information of the photos, it is difficult to classify and manage the photos according to the contents of the photos themselves.

  Therefore, a technique for automatically classifying photographs by setting conditions that the user wants to classify is known (see, for example, Patent Document 1). Here, there is a limited amount of space to save photos, but it is assumed that any images taken will be saved. It is not possible to automatically classify photos and save only the photos you need. It was difficult.

JP 2007-94518 A

  In recent years, the number of pixels of photographing apparatuses has increased, and the file size of a single photograph has become very large. Therefore, when all the pictures taken in the conventional manner are stored, there is a problem in that a semiconductor memory such as an SD card (registered trademark) or microSD has insufficient capacity and a large-capacity hard disk is required. there were.

  Furthermore, the display screen of a mobile phone or digital camera used as a photographing device is small, and there is a limit to the amount of information (image) that can be displayed on the display screen when browsing stored photos. Therefore, in order to improve the visibility, only one to at most several images can be displayed, which is not suitable for browsing a large number of photos.

  In particular, if you take pictures using the continuous shooting function or take multiple pictures of the same subject, similar images will be saved, but if those images are displayed, they will be similar to the display screen. Only an image was displayed and it was not easy to use.

  In view of the above-described problems, an object of the present invention is to provide a user-friendly photographing apparatus by providing means for efficiently storing and displaying similar images.

  In view of the above-described problems, the imaging device of the present invention displays an imaging unit that acquires an image by imaging, a storage unit that stores an image captured by the imaging unit, and an image stored in the storage unit.

The similar image determination unit that compares the points and determines whether an image similar to the captured image is stored in the storage unit, and the storage unit is captured by the imaging unit by the similar image determination unit When it is determined that the captured image is not stored in the storage unit, the image captured by the imaging unit is stored.

  In addition, the imaging apparatus of the present invention further includes a unique data management unit that manages unique data when the image is acquired by the imaging unit, and the similar image determination unit is configured to detect the image captured by the imaging unit. By comparing the unique data and the unique data of the image stored in the storage unit, it is determined whether or not an image similar to the photographed image is stored in the storage unit. .

  In the photographing apparatus of the present invention, the unique data of the image photographed by the photographing unit is compared with the unique data of the similar image determined by the similar image determining unit, and the image photographed by the photographing unit When the above shooting conditions are better, the image shot by the shooting unit is stored, and similar images are discarded.

  In addition, the photographing apparatus of the present invention further includes an auxiliary storage unit different from the storage unit in order to store an image.

  The photographing apparatus of the present invention further includes an image selection unit that selects an image stored in the storage unit, and is stored in the storage unit and feature points of the image selected by the image selection unit. A feature point of another image is compared to determine whether an image similar to the selected image is stored in the storage unit, and an image similar to the image selected by the selection unit is stored in the storage unit If the image is stored, the image similar to the image selected by the image selection unit is not displayed, or only the image similar to the image selected by the image selection unit is displayed. Features.

  According to the photographing apparatus of the present invention, the feature point is extracted by analyzing the image, the feature point of the photographed image is compared with the feature point of the image stored in the storage unit, and similar to the photographed image It is determined whether or not the image to be stored is stored in the storage unit, and when it is determined that the image captured by the capturing unit is not stored in the storage unit, the image captured by the capturing unit is stored. Will be. Therefore, when an image similar to the photographed image is already stored in the storage unit, the photographed image is not stored in the storage unit, so that the image can be efficiently stored.

  In addition, according to the photographing apparatus of the present invention, the image capturing apparatus further includes a unique data management unit that manages unique data when the image is acquired by the photographing unit, and stores the unique data of the image photographed by the photographing unit and the storage unit. By comparing with the unique data of the stored image, it is determined whether an image similar to the photographed image is stored in the storage unit. Therefore, it is possible to determine whether or not the captured image is similar to the image stored in the storage unit based on the unique data, and the image having the similar unique data is not stored. Become.

  Further, according to the photographing apparatus of the present invention, the unique data of the image photographed by the photographing unit is compared with the unique data of the similar image determined by the similar image determining unit, and the photographing condition of the photographed image is determined. If it is better, the captured image is stored and a similar image is discarded. Therefore, an appropriate image with good conditions is stored in the storage unit.

  According to the photographing apparatus of the present invention, an image can be stored in an auxiliary storage unit auxiliary storage unit different from the storage unit. Therefore, an image that is not stored in the storage unit can be stored in the auxiliary storage unit without being deleted, and can be read and displayed in the storage unit when necessary.

  In addition, according to the photographing apparatus of the present invention, the image pickup unit further includes an image selection unit that selects an image stored in the storage unit, and the feature points of the image selected by the image selection unit and the image stored in the storage unit When the feature points of the images are compared, it is determined whether an image similar to the photographed image is stored in the storage unit, and an image similar to the image selected by the selection unit is stored in the storage unit Is characterized in that an image similar to the image selected by the image selection unit is not displayed. Accordingly, similar images are not displayed on the display unit, and when the display area of the display unit is limited, it is possible to display images efficiently without displaying similar images. Become.

  Therefore, since there are few similar images when browsing images, visibility is improved even when a plurality of photos are displayed on a small screen, and visual search and confirmation of images is facilitated.

  In addition, it is possible to display only an image similar to the selected image, and it is easy to confirm a similar image even when it is desired to manually delete an unnecessary similar image.

  The photographing unit 20 is a functional unit that photographs a subject and outputs it as an image. An image obtained by photographing a subject is stored in the storage unit 60 or the auxiliary storage unit 70.

  The input unit 25 is a functional unit that receives an operation input from a user. In the present embodiment, the input unit 25 includes, for example, an operation button (dial button). Of course, other device configurations (such as a touch panel) may be used as long as a function of accepting an operation input from a user can be realized.

  The display unit 30 is a functional unit for displaying a notification instruction to the user, an operation screen, an image, and the like. Here, as the display unit 30, various display devices such as a liquid crystal display (LCD) and an organic EL panel are assumed, for example.

  The image classification unit 40 and the stored data management unit 50 are functional units that implement various processes on the captured image and the image stored in the storage unit 60 (auxiliary storage unit 70). It will be described later.

  The storage unit 60 is a functional unit that stores programs and various data for the mobile phone 1 to execute various processes and realize functions. Also, it has a function as a main storage device such as developing various programs and reading data.

  Here, the auxiliary storage unit 70 can store image data in a different location from the storage unit 60. For example, it may be another storage area built into the mobile phone 1 or an external storage device such as an SD card (registered trademark) may be connected to the mobile phone 1 and may be the external storage device.

[2.2 Configuration of Image Classification Unit and Stored Data Management Unit]
Next, detailed configurations of the image classification unit 40 and the saved data management unit 50 will be described with reference to FIG. As shown in FIG. 3, an image is input to the image classification unit 40. Here, the image input to the image classification unit 40 may be an image shot by the shooting unit 20, an image stored in the image storage area 62 of the storage unit 60, or received by the communication unit 15. It may be an image.

  The image classification unit 40 includes an image analysis unit 42, an image processing unit 44, and an image comparison unit 46.

  The image processing unit 44 is a functional unit that performs various processes on the image input to the image classification unit 40. In addition, an image that has been subjected to various processes in the image processing unit 44 is output to the saved data management unit 50.

  The image analysis unit 42 is a functional unit for extracting feature points from the input image. For example, feature points of the input image are extracted from information such as color information, density information, and luminance information of the input image. Note that any known technique may be used as a method for extracting feature points from an image, and a detailed description of the method is omitted. The extracted feature points are managed by the feature point management unit 54.

  The image comparison unit 46 is a functional unit for comparing whether or not a plurality of images are similar. As a method for determining whether or not the images are similar, for example, the determination is made based on how similar the feature points extracted from the images are, or by comparing specific data for the images. In addition, since it is a well-known technique about determination of the similar image by a similar point, the detailed description is abbreviate | omitted.

  The stored data management unit 50 is a functional unit that executes various processes based on the image input from the image classification unit 40 and outputs the processed process to the display unit 30. The stored data management unit 50 includes a data management unit 52, a feature point management unit 54, a unique data management unit 56, and a data output unit 58. In addition, a storage unit 60 and an auxiliary storage unit 70 are connected to the data management unit 52.

  The data management unit 52 is a functional unit that manages input images. For example, it is determined whether the input image is stored in the storage unit 60 (auxiliary storage unit 70) or discarded. In addition, for each image, the feature points managed by the feature point management unit 54, the unique data managed by the unique data management unit 56, and the like are managed in association with the images.

  The feature point management unit 54 is a functional unit for managing the special points of the image extracted by the image analysis unit 42.

  The unique data management unit 56 is a functional unit that acquires and manages unique information of an input image. Here, an example of the unique data will be described with reference to FIG. As shown in FIG. 4, the unique data includes, for each image (for example, “SH090401A01.JPG”), a shooting date (for example, “2009/04/01 11:00:00”) and a shooting location (for example, latitude). Longitude, location name), shooting conditions (for example, weather, focal length, aperture value, etc.), and analysis results (for example, image brightness) are stored for each image.

  The data output unit 58 is a functional unit that decodes an image output from the data management unit and outputs the decoded image to the display unit 30.

[2.3 Outline of configuration]
Next, the outline of the process for the operation of the mobile phone 1 will be described with reference to FIGS. 2 and 3. When the image captured by the image capturing unit 20 is encoded by the image processing unit 44, the feature points of the image captured by the image analysis unit 42 are extracted.

  The extracted feature points are managed by the feature point management unit 54 in the stored data management unit 50 for each image. In addition, the unique data of the captured image is also managed for each image by the unique data management unit 56. The captured image itself is stored in the storage unit 60 (auxiliary storage unit 70) by the data management unit 52 in the storage unit 60.

  When the next image is captured, the input image is processed in the same manner as the first image. That is, the feature points of the input image are extracted, and each data is stored and managed in the stored data management unit 50. If there is an already stored image (stored image), the data management unit 52 stores the stored image. Are sent to the image comparison unit 46, and the image comparison unit 46 performs comparison with the input image.

  At this time, if the saved image and the input image are similar, the data management unit 52 performs various processes on the latest input image and the shooting data such as feature points and unique data. For example, the data is not stored in the storage unit 60 and the data is discarded or stored in the auxiliary storage unit 70.

  Here, a similar image is an image in which data managed by the feature point management unit 54 is similar. However, even if the feature points are similar, if the unique data managed by the unique data management unit 56 such as the shooting date / time, location, and weather does not match, it can be saved. In this way, even a similar mountain photograph can be stored without being discarded if, for example, the location is different. By processing the captured image in this way, there is no similar image in the photograph stored in the storage unit 60, and various images can be efficiently stored in the memory.

  Further, when browsing the stored image, the data management unit 52 retrieves the image stored in the storage unit 60 and outputs it to the display unit 30 via the data output unit 58. A similar image is not stored, and even a portable terminal having a small display screen (area) with a limited number of images that can be displayed can display various images without any particular operation.

  When a plurality of small images are displayed within a small screen, a number of similar images are displayed, and browsing is facilitated without making it difficult to search for the target image. In addition, by setting the browsing conditions in the data management unit 52, it is possible to filter the image displayed on the screen and further improve the visibility. For example, only photographs having similar feature points but different data managed by the unique data management unit 56 can be displayed. In this way, it is possible to display a list of photos that show different aspects of the same landscape depending on the time and weather.

  Further, when the image discarded by the data management unit 52 is in the auxiliary storage unit 70, the data managed by the feature point management unit 54 and the unique data management unit 56 are similar, and therefore the image discarded. A list can be displayed. By doing so, the user can exchange the most favorite image among them with a photo stored in the storage unit 60.

  In addition, when the data management unit 52 discards an image that is determined to be similar by the image comparison unit 46, it simply stores preferentially the one that was taken later (or preferentially the previous one). It is also possible to preferentially save a clearer image by managing the information such as the contrast, configuration, and histogram of the image in the analysis result of the image analysis unit 42 by the specific data management unit 56. .

  Further, when it is determined that there are images that the user wants to leave at the time of browsing the image, the image is registered in the data management unit 52, and thereafter the data management unit 52 is similar to the image. As a result, the image can be stored in the storage unit 60 without being disposed of. Naturally, since the storage capacity of the storage unit 60 is limited, setting the number of sheets to be stored and disposing of the storage exceeding the number can prevent efficient memory use from being hindered.

  In addition, although the images to be managed and stored are described here as captured, similar processing is performed on images stored in another storage medium, images received by the communication unit 15, and the like. It is also possible to perform.

[3. Mobile phone processing flow]
Then, each process which the mobile telephone 1 performs is demonstrated using a flowchart.

[3.1 Image storage processing]
First, an image storage process, which is a process for determining whether an input image is normally stored or whether it is determined as a similar image and processed, will be described with reference to FIG. The image storage process is a process realized by the control unit 10 reading and executing the image storage program 64.

  First, an image is input (step S100). Here, the input image (input image) may be an image photographed by the photographing unit 20, or an image inputted to another input unit or communication unit (for example, an image received via the communication unit 15). But it ’s okay.

  Subsequently, the image analysis unit 42 analyzes the input image and extracts feature points (step S102). Here, the image comparison unit 46 determines whether an image similar to the feature point of the input image is in the image (stored image) stored in the storage unit 60 or the auxiliary storage unit 70 (step S104). .

  If there is no image similar to the saved image (step S104; No), the input image is saved (step S108). Here, the description will be made on the assumption that the data is stored in the storage unit 60, but it is needless to say that the data may be stored in the external storage unit 70 according to user settings.

  On the other hand, if there is an image similar to the input image, it is determined whether there is a stored image similar to the unique data (step S104; Yes → step S106). Here, if there is a stored image with similar unique data (step S106; Yes), similar image processing is executed (step S110). On the other hand, when it is determined that there is no image similar to the unique data (step S106; No), the input image is stored (step S108).

[3.2 Similar Image Processing]
Next, similar image processing will be described with reference to FIGS. The similar image process is a process realized by the control unit 10 reading and executing the similar image program 66, and is a process executed in step S110 of FIG.

(1) When an input image is stored in the auxiliary storage unit The similar image processing in FIG. 6 will be described. The similar image processing of FIG. 6 shows a case where the auxiliary storage unit 70 is used as an area for storing an input image.

  First, it is determined whether or not the auxiliary storage unit 70 can be used (step S200). Here, when the auxiliary storage unit 70 cannot be used (step S200; No), the input image is discarded (step S202).

  On the other hand, when the auxiliary storage unit 70 is usable (step S200; Yes), it is determined whether or not the use of the auxiliary storage unit 70 is permitted (step S204). Here, if the use of the auxiliary storage unit 70 is permitted, the input image is stored in the auxiliary storage unit 70 (step S204; Yes → step S206). If the use of the auxiliary storage unit 70 is not permitted (step S204; No), the input image is discarded (step S202).

(2) When Storage of Multiple Images is Permission The similar image processing in FIG. 7 will be described. The similar image processing in FIG. 7 shows processing when a plurality of similar images are allowed to be stored.

  First, it is determined whether or not a plurality of images are allowed to be stored (step S220). If a plurality of savings are not permitted, it is determined whether or not to save a saved image that has already been saved (step S220; No → step S222).

  If no saved image is left, the saved image is deleted, and the input image is saved instead (step S222; No → step S224). Further, when leaving the stored image, the input image is discarded (step S222; Yes → step S226).

  On the other hand, if multiple storage is permitted in step S220 (step S220; Yes), it is determined whether or not the number of storable sheets (that is, the storage capacity of the storage unit 60 or the auxiliary storage unit 70) is exceeded. If the storable number is not exceeded, the input image is saved (step S230; Yes → Step S232). If the storable number is exceeded, the process proceeds to step S222 (step S230; No). → Step S222).

(3) When Saving Images with Good Shooting Conditions The similar image processing in FIG. 8 will be described. The similar image processing of FIG. 8 shows processing in a case where an image having a better shooting condition is saved among the input image and the saved image.

  The unique data of the input image and the saved image are compared by the image comparison unit 46 (step S250). Here, from the unique data, when the shooting condition of the input image is better than the shooting condition of the saved image, the saved image is deleted and the input image is saved (step S252; Yes → step S256).

  On the other hand, when the shooting condition of the saved image is better than the shooting condition of the input image, the input image is discarded (Step S252; No → Step S254).

  In addition, there are various cases where the shooting conditions are good here. For example, when the preference is given to those taken with clear weather rather than those taken with rain due to the setting, or with a smaller aperture value. For example, it may be determined that the image has good shooting conditions and is given priority.

[3.3 Image display processing]
Next, image display processing will be described with reference to FIGS. The image display process is a process realized by the control unit 10 reading and executing the image display program 68. The image display process is a process executed when a (list) display of stored images is performed on the display unit 30.

(1) When there is an image similar to a display image The image display process of FIG. 9 is demonstrated. The image display processing of FIG. 9 shows processing that is not displayed when an image similar to the image to be displayed next is present in an image displayed on the display unit 30 (hereinafter referred to as “display image”). Yes.

  First, in the state where the display image is displayed on the display unit 30, the image to be displayed next is selected by the control unit 10 (step S300). Here, an image selected to be displayed next on the display unit 30 is referred to as a “selected image”.

  Then, it is determined whether there is an image similar to the display image already displayed (step S302). Here, when an image similar to the selected image is not displayed, the selected image is displayed on the display unit 30 (Step S302; No → Step S304), and an image similar to the selected image is already displayed. Does not display the selected image (step S302; Yes → step S306).

  In this way, many similar images are not displayed on a small screen, and each image is different, so visibility is improved and the desired image can be found immediately. This makes it easier for the user to view images. An image of the display operation when executed in this operation flow is shown as a display screen W100 in FIG.

(2) When Images with the Same Unique Data are not Displayed The image display process in FIG. 11 will be described. The image display processing in FIG. 11 will be described when even if there is an image similar to the image to be displayed next, if the unique data is not the same, the display processing is performed.

  First, the selection image is selected by the control unit 10 while the display image is displayed on the display unit 30 (step S320). Here, it is determined whether there is a display image having the same unique data as the selected image (step S322).

  If there is no display image having the same unique data as the display image, the selected image is displayed (step S322; No → step S324). On the other hand, when a display image having the same unique data as the selected image is already displayed, the selected image is not displayed (step S322; Yes → step S326).

  By doing this, only images that are similar but have different unique data will be displayed on the screen, and only images with different locations or similar seasons will be displayed even in the same landscape. It becomes possible. An image of the display operation in this processing flow is shown as a display screen W200 in FIG.

(3) Case of Displaying Only Similar Images The image display process in FIG. 13 will be described. The image processing in FIG. 13 will be described for displaying only similar images.

  First, the selected image is selected by the control unit 10 while the display image is displayed on the display unit 30 (step S340). Here, it is determined whether or not there is an image similar to the selected image in the display image (step S342).

  If there is no image similar to the display image, the selected image is not displayed (step S342; No → step S344). On the other hand, when there is an image similar to the selected image in the display image (step S342; Yes), it is determined whether the unique data of the display image and the selected image is similar (step S346).

  Here, if the unique data of the display image and the selected image is not similar, the selected image is not displayed (step S346; No → step S344). On the other hand, when the inherent data of the display image and the selected image is similar, the selected image is displayed (step S346; Yes → step S348).

  In this way, only what appears to be the same image is displayed on the screen. In this state, the user can select the most favorite image from the similar images, and when the image is in the auxiliary storage unit 70, the user can save the image again in the storage unit 60. An image of the display operation in this processing flow is shown as a display screen W300 in FIG.
