  Hereinafter, preferred embodiments of the present invention will be illustratively described in detail with reference to the drawings. However, the components described in this embodiment are merely examples, and the scope of the present invention is not limited to them.

First Embodiment
The configuration of a computer apparatus constituting the information processing apparatus of this embodiment will be described with reference to the block diagram of FIG. The information processing apparatus may be realized by a single computer apparatus, or the functions may be distributed to a plurality of computer apparatuses as needed. When it comprises a plurality of computer devices, they are connected by a Local Area Network (LAN) or the like so that they can communicate with each other.

  In FIG. 1, a control unit 101 controls the entire information processing apparatus 100, and is, for example, a central processing unit (CPU). The read only memory (ROM) 102 stores programs and parameters that do not need to be changed. The Random Access Memory (RAM) 103 temporarily stores programs and data supplied from an external device or the like. The external storage device 104 is a hard disk drive (HDD) fixedly installed in the information processing apparatus 100, a solid state drive (SSD) configured by a flash memory, a hybrid drive or a memory card using a hard disk and a flash memory in combination . The external storage device 104 stores programs such as an operating system (OS). Also, the external storage device 104 stores the content search application program software (hereinafter referred to as a content search application) of the present embodiment, and stores content files such as image files and music files. The input interface 105 receives a user operation and is connected to an input device such as a pointing device, a keyboard, or a touch panel for inputting data. The Bit Move Unit (BMU) 106 controls, for example, data transfer between memories (for example, between the VRAM 107 and other memories), and between memory and each I / O device (for example, the network interface 109). Video RAM (VRAM) 107 draws an image to be displayed on the display device 111. The image generated in the VRAM 107 is transmitted to the display device 111 in accordance with a predetermined rule, whereby the display device 111 displays the image. The network interface 109 is connected to a network line 110 such as the Internet. A system bus 112 communicably connects the units 101 to 109.

  An example of the structure of the content file according to the present embodiment is shown in FIG. In FIG. 2, the case where the content file is an image file obtained by continuous shooting with an imaging device will be described. The content file 200 stores metadata 201 indicating the attribute. Also, as the content data 210, a plurality of RAW data obtained for each successive shooting with the imaging device is stored. The metadata 201 of the content file 200 stores, as representative thumbnail data 202, display thumbnail data of any one of a plurality of content data 210 included in the content file 200. For example, content data 210 obtained at a predetermined number from the top is set as representative content data. Alternatively, content data 210 obtained when a predetermined operation is performed at the time of shooting is set as representative content data.

  The metadata 201 also stores attribute information such as the file name of the content file and the creation date and time of the content file. Each content data 210 has metadata 211 indicating its attribute, and RAW entity data as the content data entity 213. The metadata 211 of the content data 210 stores display thumbnail data 212 generated by performing development processing and compression processing on the RAW entity data. In addition, it stores attribute information such as shooting information such as shooting date and time of RAW entity data, setting value of ISO sensitivity at shooting, camera model name used at the time of shooting, and editing information such as rating given by user operation. .

  In the case of an image file obtained by single shooting, only one content data 210 is stored instead of a plurality of content files 200, but the other configuration is the same as in the case of an image file obtained by continuous shooting. It is.

  An example of the content list screen according to the present embodiment is shown in FIG. FIG. 3A illustrates a case where a list of image files among the content files stored in the external storage device 104 of the information processing apparatus 100 is displayed. In the content list screen 300, display thumbnail data included in each image file is displayed in a matrix. Reference numeral 301 denotes display thumbnail data of an image file having a plurality of RAW data, and representative thumbnail data 202 is displayed. Reference numeral 302 denotes display thumbnail data of an image file having one RAW data. Further, the display thumbnail data is displayed so as to distinguish between the case where the image file has a plurality of RAW data (301) and the case where a single RAW data is present (302). For example, in FIG. 3A, in the case of having a plurality of RAW data (301), the display mode is different from that in the case of having a single RAW data (302) so as to indicate an overlap.

  The operation of the information processing apparatus 100 according to the present embodiment will be described with reference to the flowchart of FIG. The following operation is realized by the control unit 101 of the information processing apparatus 100 reading and executing the OS and the content search application from the external storage device 104 and controlling each unit according to them.

  The control unit 101 displays the filtering condition dialog 311 in response to the user's operation (S401). An example of the filtering condition dialog 311 is shown in FIG. The filtering condition dialog 311 displays a filtering item 312. Item 312 includes, for example, as camera information, camera model name at the time of shooting, lens model name, ISO sensitivity, shutter speed, aperture value, lens correction, shooting mode, shooting date and time, etc., editing information, rating, classification tag, color There is a label etc. FIG. 3B shows a state in which "rating" is selected among the plurality of items 312, a parameter 313 of "rating" is displayed, and a state in which "five stars" is selected therefrom. Show. Not only the "rating" but also a plurality of items 312 may be set as filtering conditions at the same time. Further, not only "five stars" but also a plurality of values may be set as filtering conditions at the same time for "rating".

  When receiving the item of the filtering condition and the input of the parameter thereof on the filtering condition dialog 311, the control unit 101 stores the item in the RAM 103 (S402), and executes the filtering process described later (S403). Then, the control unit 101 extracts display thumbnail data corresponding to the content file whose display setting is "on" as a result of the filtering process, and displays the thumbnail data on the content list screen 300 (S404). For example, if the filtering condition is "five stars" of "rating", display thumbnail data of the content file 200 satisfying the condition is displayed as shown in FIG. 3C.

  Next, the filtering process of step S404 will be described with reference to the flowchart of FIG.

  The control unit 101 sets the number of content files to be filtered to the variable M (S501), and sets 1 as an initial value to the count j (S502). The control unit 101 determines whether the j-th content file 200 includes a plurality of content data 210 (S503). If the j-th content file 200 does not include a plurality of content data 210 (No in S503), the variable N is set to 1 (S504). In step S503, if the metadata 201 of the content file 200 contains, for example, information indicating that it has been obtained by continuous shooting, the control unit 101 determines that the content data 210 is included.

  If a plurality of content data are included (Yes in S503), the control unit 101 determines whether the filtering condition is a common item among the plurality of content data included in the content file (S505). In the present embodiment, information indicating whether or not common is stored in the RAM 103 for each item of the filtering condition.

  For example, in the case where the content file is an image file storing a plurality of image data acquired by continuous imaging of the imaging device, the imaging device and the lens are not changed in the middle of continuous imaging. The lens name is determined to be a common item. If the ISO sensitivity, the shutter speed, and the aperture value are set to auto, the setting values may be changed during continuous shooting, and therefore it is determined that the items are not common items. On the other hand, when the fixed values are set to the ISO sensitivity, the shutter speed, and the aperture value, the setting value is not changed during continuous shooting, so it is determined that the items are common items. The lens focal length is determined to be a common item when the lens is a single focus lens, since the focal length does not change. On the other hand, when the lens is a zoom lens, it is determined that the lens focal length is not a common item because the focal length may be changed during continuous shooting. When the user can set the rating and the image quality adjustment information for each content data, it is determined that the item is not a common item.

  If it is determined that the filtering condition is not a common item (No in S505), the control unit 101 substitutes the number of content data 210 included in the j-th content file 200 into a variable N (S506). Is set to 1 as an initial value (S507). The control unit 101 compares the information stored in the metadata 211 of the i-th content data 210 with the filtering condition, and determines whether they match (S508). If they match (Yes in S508), the control unit 101 sets the display setting of the j-th content file 200 to "on" (S509). On the other hand, if they do not match (No in S508), the control unit 101 adds 1 to the count number i (S510). If the count number i is compared with the variable N and the count number i is equal to or less than the variable N (No in S511), the control unit 101 executes the process of step S508 on the i-th content data 210. Then, if the count number i is larger than N, that is, if none of the content data 210 matches the filtering condition (Yes in S511), the control unit 101 sets the display setting of the j-th content file 200 to “off”. (S512).

  In addition, if the filtering condition is a common item (Yes in S505), the control unit 101 stores the metadata 211 of representative content data among the plurality of content data 210 included in the j-th content file 200. The information is compared with the filtering condition (S513). If the comparison results in a match (Yes in S513), the control unit 101 sets the display setting of the j-th content file 200 to "off" (S514).

  When the above process is completed for the j-th content file 200, the control unit 101 adds 1 to the variable j (S515), and if the variable j is larger than M (S516), the process ends. If the variable j is less than or equal to M, the processing of S 503 and subsequent steps is executed for the j-th content file.

  If the content file 200 includes a plurality of content data 210 and the filtering condition is not a common item, the representative content data may be changed to other content data that satisfies the filtering condition.
