The stored image data is read out and displayed on the display unit 18.

The imaging unit 10 is controlled by the CPU 15 based on the set imaging conditions (for example, aperture value, exposure value, etc.), and generates image data and through image information that are digital signals from the incident light.
That is, the optical system 12 controls the amount of light incident from the lens 11 based on the set aperture value, and forms an image on the light receiving surface of the image sensor 13. The image sensor 13 controls the exposure time of the image sensor 13 based on the set exposure value, and photoelectrically converts the image information imaged on the light receiving surface. The A / D converter 14 converts the image information of the analog signal output from the image sensor 13 into a digital signal.
As described above, when the operation unit 17 (shutter button) is pressed and imaging is instructed by the user, the imaging unit 10 receives light incident on the lens 11 based on imaging conditions such as a set aperture value and exposure value. Image data is generated from the image data and output to the CPU 15.

Next, the playback device 3 will be described in detail.
The CPU 15 comprehensively controls the imaging apparatus 1, for example, data writing means, data reading means, sequence management means, image processing means, header creation means, management file generation means, management file analysis means, management file collation means And function as a management file correction means.
The CPU 15 functions as a data writing unit that writes the image data generated by the imaging unit 10 to the external storage medium 2. The CPU 15 functions as a display unit that reads image data from the storage medium 2 and displays the image data on the display unit 18.

Further, when an arbitrary operation is instructed by the user via the operation unit 17 as a sequence management unit, the CPU 15 controls each component according to a program stored in the memory unit 20. For example, the CPU 15 supplies power from a battery (not shown) included in the power supply unit 19 to each unit when the operation unit (for example, a power switch) 17 is pressed and a power-on instruction is given from the user. In addition, when the operation unit (for example, a shutter button) 17 is pressed and imaging is instructed by the user, the CPU 15 controls the imaging unit 10 according to the imaging conditions stored in the memory unit 20.
The imaging condition is a condition at the time of shooting, and is determined by parameters such as an aperture value, a shutter speed, an exposure value, a focus point, or a depth of field. The imaging apparatus 1 according to the present embodiment has an imaging mode for imaging a subject under imaging conditions according to the subject and the environment at the time of imaging. For example, a portrait mode for imaging a person, There are a landscape mode for capturing a landscape, a backlight mode for correcting a decrease in illuminance of a subject in shooting with backlight, and the like, and imaging conditions corresponding to the subject are set in advance.

  Further, the CPU 15 is connected to the counter 23, and when the user gives an instruction to turn on the power, the count of the counter 23 is reset to zero. When the CPU 15 stores the image data captured by the imaging unit 10 in the storage medium 2, the CPU 15 increases the count number of the counter 23 by one according to the number of recorded image data.

As an image processing unit, the CPU 15 refers to the image processing conditions stored in the memory unit 20, and processes image data recorded in the storage medium 2 and through image information stored in the buffer memory unit 16. Image processing.
The CPU 15 functioning as the image processing means has, for example, a face recognition function, performs image processing using the face recognition function on through image information or image data, and corresponds to a “face” in the image information. Is detected. Further, the CPU 15 determines whether or not the “face” detected by the face recognition function is a smile, and based on the smile detection function for detecting “smile” and through image information, the imaging environment and target at the time of imaging A scene recognition function for recognizing a captured scene according to (for example, a person or a building), an image editing function for performing arbitrary image processing on image data in accordance with a user instruction input via the operation unit 17, etc. Is provided.

Furthermore, the CPU 15 determines, as a header creation unit, which category the image data obtained by the imaging unit 10 belongs to among a plurality of preset categories. The CPU 15 assigns category information representing each category to the header area of the image data for which the category has been determined, and stores the category information in the storage medium 2. The header area includes arbitrary attribute information of the image data. In addition to the category information, for example, the imaging conditions of the image data obtained by the imaging unit 10, the imaging date and time, and the image processing conditions processed by the CPU 15 Alternatively, the model name or manufacturer name of the imaging apparatus 1 is included.
Note that a plurality of preset categories and category determination methods, management file generation means, management file analysis means, management file collation means, and management file correction means of the CPU 15 will be described in detail later.
The buffer memory unit 16 is a storage area for temporarily storing image data captured by the imaging unit 10, and temporarily stores, for example, through image information.

The operation unit 17 includes, for example, a power switch, a shutter button, and other operation keys. When operated by the user, the operation unit 17 receives an input of a user instruction and outputs it to the CPU 15.
The display unit 18 is, for example, a liquid crystal screen, and displays an image based on image data, contents operated by the operation unit 17, and the like. The display unit 18 displays an image reproduced by the reproduction device 3, and the reproduction device 3 displays, for example, a standard display mode in which image data stored in the storage medium 2 is displayed in order of the latest imaging date and time, or a category. The user sets a reproduction mode such as a classification reproduction mode in which the image data classified according to the category is displayed for each category. That is, an instruction input from a user who selects an arbitrary playback mode is accepted.
The power supply unit 19 includes a battery and a power supply circuit. When the user gives an instruction to turn on the power through the operation unit (power button) 17, the power of the battery is supplied to each component through the power supply circuit.

  The memory unit 20 stores on / off of an XML (Extensible Markup Language) analyzed flag and an XML collated flag. This XML analyzed flag indicates whether or not the XML analysis processing has been executed after the power is turned on, and the XML verification flag indicates whether or not the XML verification processing has been executed after the power is turned on. These flags are both turned on and off by the CPU 15. In other words, the XML analyzed flag and the XML collated flag are turned off when the user gives an instruction to turn on the power via the operation unit (power switch) 17, and turned on when the analysis processing or collation processing of the XML file is performed by the CPU 15. Can be switched to. Details of the XML analysis process and collation process will be described later.

This XML analyzed flag or XML collated flag is, for example, whether or not the display is performed in the first classification / reproduction mode after the power is turned on when an image is displayed on the display unit 18 using the classification / reproduction mode described later. It can be used as management display information for determining whether or not. Here, the management display information is identification information for identifying image data obtained by the imaging unit 10 (for example, a file name of image data), and attribute information given according to the image content of the image data. A display mode (for example, a classification display mode) for displaying an image based on the image data on the display unit 18 with reference to management information (for example, an XML file to be described later) representing a correspondence relationship (for example, category information or imaging conditions). ) Is information indicating whether or not execution has been performed.
In addition, the memory unit 20 stores a program referred to by the sequence management unit of the CPU 15, imaging conditions, image processing conditions, and the like.

The I / F unit 21 is connected to a removable storage medium 2 such as a card memory, and performs writing, reading, or erasing of information on the storage medium 2.
The bus 22 is connected to the imaging unit 10, the CPU 15, the buffer memory unit 16, the display unit 18, the power supply unit 19, the memory unit 20, and the I / F unit 21, and transfers data and the like output from each unit.

The storage medium 2 stores image data input from the imaging device 1 via the I / F unit 21 in a folder hierarchical structure as shown in FIG.
Here, the folder hierarchy structure of the storage medium 2 will be described below with reference to FIG. The folder hierarchical structure in which the storage medium 2 stores image data is based on the camera file system standard (Design Rule for Camera File system; hereinafter referred to as DCF), which is a format used when storing image data in a computer. It is. The storage medium 2 stores image data in a hierarchical structure based on the DCF, so that the image data is output to a computer or the like, and also provided to peripheral devices such as a printer connected via the computer. Can do. That is, the image data in the storage medium 2 is recognized and read by the connected computer.

As shown in FIG. 2, the folder hierarchical structure of the storage medium 2 includes a DCIM folder 221 and a management folder 222 below the highest root folder 201, and image data is stored in the management folder 222 in the DCIM folder 221. XML file “kanri01.xml” is stored.
Below the DCIM folder 221, subfolders 231 and 232 that are uniquely provided for each imaging apparatus 1 are provided. The subfolders 231 and 232 are assigned folder names according to the manufacturer and model of the imaging apparatus 1, respectively. ing. For example, “NICON001” is attached to the folder 231, and “NICON002” is attached to the folder 232.
Below this folder 231, a still image folder 241, a moving image folder 242, and an edited image folder 243 are provided for each type of image data. Below the still image folder 241, folders 251, 252, and 253 are a moving image folder. Folders 256 and 257 are provided below 242. Note that the image data of the imaging apparatus 1 according to the present embodiment is stored in the folders 251, 252, and 253, and each can store a maximum of 999 pieces of image data.
The folder 251 stores image data “DCIM1101.jpg” and image data “DCIM1102.jpg”.

  In addition, the XML file stored in the management folder 222 is given according to the file name of the image data for identifying the image data obtained by the imaging unit 10 and the image content of the image data as described above. Management information indicating a correspondence relationship with the attribute information (for example, category information and imaging conditions). The XML file is information in which image data and attribute information thereof are described in association with XML, which is one of markup languages for describing the meaning or structure of a document or data.

Next, the management file generation means, management file analysis means, and management file collation means of the CPU 15 will be described with reference to FIG. FIG. 3 is a schematic diagram for explaining the category classification of image data given by the header creation means of the CPU 15.
As shown in FIG. 3, there are nine categories of image data classified by the imaging apparatus 1, for example, “smile”, “person”, “cooking”, and “other images”. 9 is assigned.
The CPU 15 determines the category of the image data using an image processing unit, a header creation unit, and the like, and writes the category information of the determined category in the header area of the image data.

For example, the CPU 15 determines that the image data for which “smile” is recognized by the smile detection function is the category “smile”, and writes the category number 1 corresponding to the category “smile” in the header area of this image data. In addition, for example, when the portrait mode is set as the imaging mode, the backlight mode is set as the imaging mode, or when the “face” is detected by the face recognition function, the CPU 15 The image data is determined to be “person”, and category number 2 corresponding to the category “person” is written in the header area. Similarly, the CPU 15 determines the image data as “cooking”, “landscape”, “night view”, and “close-up” according to the imaging mode (cooking, landscape, night view, macro), and displays the image data in the header area of each image data. Write categories 3, 4, 5, and 6.
Further, the CPU 15 writes the category 7 corresponding to the category “edited image” in the header area of the image data once saved in the still image folder 241 and edited by the user via the operation unit 17. Save in the folder 243. When the moving image data which is continuous image data is obtained by the imaging unit 10, the CPU 15 writes the category number 8 corresponding to the category “moving image” in the header area of the moving image data. When the CPU 15 determines that the image data obtained by the imaging unit 10 does not correspond to any of the above, the CPU 15 writes the category number 9 corresponding to the category “other image” in the header area of the image data.

Here, the management file generation means of the CPU 15 will be described.
For example, when the CPU 15 writes the file name “DCIM1101.jpg” to arbitrary image data captured by the imaging unit 10 and determines that the image data is in the category “smile”, the CPU 15 sets the category number 1 in the header area. Write.
The CPU 15 stores the image data “DCIM1101.jpg” in the folder 251 of the storage medium 2 and, as management file generation means, the file name “DCIM1101.jpg” of the image data and the attribute information of the image data. “Category 1” is associated and stored in the XML file “kanri01.xml” in the management folder 222 of the storage medium 2.

Further, when the XML analyzed flag stored in the memory unit 20 is OFF, the CPU 15 analyzes the XML file “kanri01.xml” in the management folder 222 as a management file analysis unit. That is, the CPU 15 performs an analysis process on the XML file as a management file analysis unit, and the syntax described in the XML file is appropriate as information associating the file name of the image data with the category information of the image data. Whether or not it is described in the language for describing the XML syntax. When the management file analysis process ends, the CPU 15 switches on the XML analyzed flag stored in the memory unit 20.
If the CPU 15 determines that the syntax of the XML file is appropriately described, the CPU 15 executes the next process assuming that there is no problem in the XML file. On the other hand, if it is determined that the information is not properly described, the CPU 15 displays that the XML file is not an appropriate XML file, displays an error message on the display unit 18 or indicates that the collation processing is performed, and ends the processing.

Further, when the XML collation completed flag stored in the memory unit 20 is off, the CPU 15 collates the image data of the DCIM folder 221 and the XML file of the management folder 222 as management file collation means. That is, as a management file collating unit, the CPU 15 has a correspondence relationship between the attribute information associated with the file name of the image data in the XML file, and the attribute information described in the file name of the corresponding image data and the header area. It is determined whether or not it matches the corresponding relationship. When the management file collation process ends, the CPU 15 outputs a collation result and switches on the XML collation completed flag stored in the memory unit 20.
Further, the CPU 15 refers to the collation result output from the management file collating unit as the management file correcting unit, and if the correspondence relationship of the XML file and the correspondence relationship of the image data match, it is determined that there is no problem in the XML file. Execute the process. On the other hand, if the correspondence relationship between the XML file and the correspondence relationship between the image data does not match based on the collation result, the CPU 15 determines that the XML file and the image data do not correspond to information as management file correction means, Modify according to the correspondence of the image data. For example, the CPU 15 detects a non-matching part, reads information of image data corresponding to the non-matching part, and writes correct information to an XML file.

Next, an operation method of the imaging apparatus 1 will be described with reference to FIGS. FIG. 4 is a flowchart illustrating an example of an operation method of the imaging apparatus 1 when power-on is instructed.
As shown in FIG. 4, when the operation unit (power switch) 17 is pressed and the user instructs the imaging apparatus 1 to turn on the power, the power supply unit 19 supplies the power of the built-in battery to the CPU 15 and other components. Then, the imaging device 1 is activated (step ST1). When the imaging apparatus 1 is activated, the CPU 15 turns off the XML analyzed flag in the memory unit 20 (step ST2) and turns off the XML collated flag in the memory unit 20 (step ST3).
The imaging apparatus 1 according to the present embodiment includes an imaging mode activation setting that activates as an imaging mode in which imaging can be performed by the imaging unit 10 when the operation unit (power switch) 17 is pressed by the user, and a storage medium 2 can be set as a playback mode that can be displayed as a playback mode that can be displayed on the display unit 18, and is selected in advance by the user via the operation unit 17, and is stored in the memory unit 18. Is remembered.

Next, an example of an operation method in the classification reproduction mode of the imaging apparatus 1 will be described with reference to FIG. FIG. 5 is a flowchart illustrating an example of an operation method of the imaging apparatus 1 when reproduction in the classification reproduction mode is instructed.
As shown in FIG. 5, in the imaging apparatus 1, for example, when the playback mode activation setting is selected in advance by the user, the operation unit (power switch) 17 is pressed, and the user instructs the imaging apparatus 1 to turn on the power. Then, the reproduction mode is activated (step ST21), and as shown in FIG. 4, the XML analyzed flag and the XML collated flag are turned off, and the count number of the counter 23 is reset.
Thereafter, when the user selects a classification reproduction mode for reproducing an image for each category (step ST22), the CPU 15 determines whether the XML analyzed flag stored in the memory unit 20 is off or on. Is determined (step ST23).

If the XML analyzed flag is off (step ST23-YES), the CPU 15 reads the XML file from the management file 222 of the storage medium 2 (step ST24), and analyzes the XML file (step ST25). If the XML file is appropriately described, the CPU 15 ends the analysis of the XML file and turns on the XML analyzed flag of the memory unit 20 (step ST26).
Next, the CPU 15 matches the correspondence between the file name of the image data stored in the DCIM file 221 of the storage medium 2 and the category number in the header area with the correspondence between the file name written in the XML file and the category number. The collation process of whether or not to perform is performed (step ST27). When the CPU 15 detects a non-matching portion, the CPU 15 corrects the description content of the XML file according to the correspondence between the file name of the image data and the category number of the header area. When collation of all the image data is completed, that is, when the correspondence between the file names of all the image data and the category number of the header area matches the description content of the XML file, the CPU 15 stores the XML in the memory unit 20. The collated flag is turned on (step ST28).
If the XML collated flag is on in step ST23, it is determined that XML analysis processing and collation processing have already been performed since the power was turned on, and the above processing is not performed (step ST23- NO).

Next, an example of an operation method in the imaging mode of the imaging apparatus 1 will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of an operation method of the imaging apparatus 1 when an image is captured by the imaging unit.
As illustrated in FIG. 6, in the imaging apparatus 1, for example, when the imaging mode activation setting is selected in advance by the user, the operation unit (power switch) 17 is pressed, and the user instructs the imaging apparatus 1 to turn on the power. Then, the imaging mode is activated (step ST31), and as shown in FIG. 4, the XML analyzed flag and the XML collated flag are turned off, and the count number of the counter 23 is reset.
Thereafter, when the operation unit (shutter button) 17 is pressed by the user and imaging is instructed, the imaging unit 10 captures an image and generates image data (step ST32). The CPU 15 assigns, for example, a file name “DCIM1101.jpg” to the image data, and determines to which category the image data belongs according to the header creation means. If it is determined that the image data is in the category “smile”, the CPU 15 writes the category 1 in the header area of the image data “DCIM1101.jpg” and then saves it in the folder 251 of the storage medium 2 (step ST33), the counter 23 is set to 1.

Next, the CPU 15 determines whether or not the count number of the counter 23 is 1 (step 34), and when the count number is 1 (step ST34-YES), the XML analysis completed stored in the memory unit 20 is completed. It is determined whether or not the flag is off (step ST35).
If the XML analyzed flag is off (step ST35-YES), the CPU 15 reads the XML file from the management file 222 of the storage medium 2 (step ST36), and analyzes the XML file (step ST37). When the XML file is appropriately described, the CPU 15 ends the analysis of the XML file and turns on the XML analyzed flag of the memory unit 20 (step ST38). If the XML file is not properly described, the CPU 15 displays that fact on the display unit 18.
Next, the CPU 15 associates the file name of the image data “DCIM1101.jpg” recorded in the storage medium 2 in step ST33 and the category information, and writes them in the XML file of the storage medium 2. If the count number of the counter 23 is 2 or more in step ST34, or if the XML analyzed flag is turned on in step ST35, the XML file is not analyzed and recorded in step ST33. The image data file name and category information are associated with each other and written to the XML file of the storage medium 2 (step ST39).

As described above, the imaging device 1 according to the present embodiment refers to the XML file in which the category information and the file name are associated with each other, and executes the classification reproduction mode, the image data of the DCIM file 20, and the management The file 222 is checked against the XML file. Thereby, according to the category information attached to the header area of the image data, the image data can be displayed on the display unit 18 for each category, and an appropriate classification reproduction mode can be ensured.
In addition, the imaging apparatus 1 according to the present embodiment is characterized in that only an XML file is analyzed without collating the XML file in an imaging mode or a playback mode other than the classification playback mode. Thereby, when the classification reproduction mode with reference to the XML file is not executed, the time-consuming collation process is not performed. For this reason, the load concerning an imaging device can be reduced.
Furthermore, when the classification reproduction mode is not used, the XML file and the image data do not have to match, so that there is no problem in reproduction. Further, the CPU 15 can detect a defect in the XML file in a short time by performing an analysis process having a shorter processing time than the collation process.

Note that the imaging apparatus 1 according to the present embodiment is not limited to the above-described configuration, and can be changed, replaced, and converted as follows.
For example, in the above description, the example in which the CPU 15 uses the XML collation flag as the management display information has been described. However, the present invention is not limited to this. For example, after the power is turned on, the display unit 18 is displayed in the classification display mode. A classification display flag indicating whether or not image display has been executed may be further stored. This classification display flag is turned off by the CPU 15 when power-on is instructed, and is switched on when reproduction in the classification reproduction mode is executed. Thereby, the CPU 15 determines whether or not the above-described classification flag is off in place of the XML collated flag in step ST23 of the operation flow in the classification reproduction mode described with reference to FIG.

In the above description, the XML file analysis process and the collation process have been described with reference to FIG. 5 when the image display is first performed in the classification reproduction mode after the power is turned on. In addition to this, for example, the present invention may be configured to be performed when image data stored in the storage medium 2 is deleted. That is, as shown in FIG. 5, when the user instructs the CPU 15 to delete the image data stored in the storage medium 2 via the operation unit 17 after the power-on is instructed, the CPU 15 5 may be configured to execute the processing from step ST24 to step ST28.
Further, when the imaging apparatus 1 includes an arbitrary external terminal connection unit (not shown) and is connected to an external apparatus such as a personal computer, the deletion of the image data in the storage medium 2 is instructed by an instruction from the external apparatus. In this case, as described above, the CPU 15 may execute the processing from step ST24 to step ST28 in FIG.

  In the above description, the XML analyzed flag and the XML collated flag have been described as being turned off when the power-on is instructed and the imaging apparatus 1 is activated using FIG. 4. However, the present invention is not limited to the present invention. For example, the CPU 15 may detect that the battery or the storage medium 2 included in the power supply unit 19 has been removed from the imaging apparatus 1 and turn off the XML analyzed flag and the XML collated flag. In this case, for example, the imaging device 1 includes a cover opening / closing detection unit that detects opening / closing of a cover member that covers a housing unit in which the battery or the storage medium 2 is accommodated in the imaging device 1, and detects insertion / extraction of the battery or the storage medium 2. It has the composition to do.

  Furthermore, as described above, the image data of the storage medium 2 is stored in the folder 231 and a maximum of 999 pieces of image data can be stored. As described with reference to FIG. 6, when the image data generated by the imaging unit 10 is stored in the storage medium 2 in step ST <b> 33, the CPU 15 exceeds the number that can be stored in the folder 231, and step ST <b> 39. The configuration may be such that writing to the XML file is not performed.

In addition, the above-described operation process in the imaging device 1 and the playback device 3 can be used as a program to be executed by a computer or a computer-readable recording medium as the program, and is read and executed by the computer system.
