Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic imaging device,
For details, add a directory structure to the applied recording medium.
To record the image information, or
Playing back image information recorded with bird structure
The invention relates to an electronic imaging device that enables it. 2. Description of the Related Art In recent years, various types of electronic imaging devices have been developed.
Still cameras are commercialized and used for various purposes.
Swelling. In the above-mentioned electronic still camera, many
Chill image information can be stored on memory cards, floppy disks, etc.
It is recorded as a data file on an information recording medium.
Naturally, the searchability of the image information is good
The badness is the commercial value of the electronic still camera,
It will determine the utility value. On the other hand, Pasoko, which is now widely used in various fields,
DOS (disk operating system)

File selection and specification methods are particularly complex for many files.
This is very useful if it branches. The file system of the personal computer is
In this case, the size of each of the above recorded files may vary.
Therefore, to use the memory area economically,
File data is stored in free space in memory,
A cluster which is a unit of area is searched for and recorded sequentially.

Useful for organizing. However, a recording format having a high affinity with a personal computer is used.
If the format is adopted, it is necessary to introduce a file name.
In the electronic camera, the user inputs the file name
Is complicated, the number of operation members is increased,
It is not preferable in use, for example. The present invention has been made to solve the above-mentioned problems.
Recorded in a directory structure.
In an electronic imaging device that performs
Registered shooting information without burdening file name creation
Electronic imaging device capable of identifying information and photographing frame number

Power switch 24 for turning off and release switch
Recording switch 25 is disposed. In addition, the camera
Behind the upper surface of the main body 20, operation switches such as recording and playback operations are provided.
Group 11, display of recording / reproduction, and hierarchical delay of image data.
Depending on the directory (root directory, subdirectory)
File information (information on how the file is structured)
An LCD display unit 12 for performing display is provided. FIG. 2 is a block diagram of the signal processing system of the SMC shown in FIG.
FIG. As shown in FIG.
In the case of recording or reproducing images,
Insert the card into the card interface (I / F) 13
Then, the recording / reproducing state is set. First, in the shooting state
Indicates that an object image is provided on the imaging circuit 2 by the photographing lens 1.
Image on an image sensor such as a CCD
Output to the A / D converter 3. A / D converter 3
Image data corresponding to the image signal digitized by
Is converted into an analog signal again by the D / A converter 5.
After that, the video encoder 6 performs a predetermined encoding process.
And output as a video signal. The playback data
If the data is playback data from an unrecorded area,
A video signal is generated by a mute signal from the stem controller 10.
The encoder 6 performs a mute process. Further, image data is recorded on a memory card.
When the image data is read from the RAM 4,
The data is read out in units of clocks, and DCT (Discrete
Orthogonal transformation / encoding processing using Cosaine Transform)
The data is compressed by the card I / F via the bus.
13 is input. Therefore, the designation on the memory card 14
The above-described compressed data is written in the specified area. This
Is defined by the above hierarchical directory

Each piece of image data is treated as one file
You. Then use the file system of the hierarchical directory.
The recording / reproduction of the image file is managed using the image file. This
Here, about the file system in this SMC,
Will be described below. The memory card 14 stores the FA
FAT area where T information is recorded, basic directory
Directory area where image information is recorded, image data
Memory area is allocated to the data area where the data body is recorded
Have been. Then, the unused state, that is, new data
With no directory area, image data
When recording, the basic route as shown in FIG.
File names, file A, file B,
File C, File D, etc. are registered and specified
Each image data is sequentially recorded in the memory area.
In FIG. 4, ￥ indicates a root directory.
You. So, in the root directory,
Creates the root directory as shown in FIG.
Subdirectory b is registered in the
A sub-directory of the second layer of the directory name b is secured.

The information is written to the directory entry described later and the information
The file is accessed based on the. It should be noted that the sub-directory b has a sub-
A directory d can be created. And sub
Files such as file J and file K can be recorded in directory d
Noh. Further, as shown in FIG.
Creating another subdirectory name c in the directory
File H, File I, etc. are registered in the two-level directory
Recording becomes possible. Recorded in each of the above subdirectories
Image files, for example, have the same theme
It is a scene screen or an image according to the series by shooting period
It can be registered in the directory in a state where it is classified
You. When reproducing image data, a root directory
Reload the image data files A, B, and C in the directory sequentially.
Not only raw but also classified image data files
If you want to play back only E, F and G,
By selecting and playing the directory b,
It is possible to reproduce data that matches the target. FIG. 6 shows an image data file of this SMC.
Further includes an example of the configuration of the hierarchical directory of FIG.
It is the figure shown physically. This hierarchical directory contains a

The name is registered. File data is supported in the above attributes.
Subdirectory or file type.
Also, the image file data is determined by the top cluster number.
Access to data or subdirectories
Becomes possible. For image files, make up one file
The cluster number of the area where the data to be recorded is
The first cluster number and the following cluster number information
Information is written to the FAT area of the memory card 14.
You. In addition, the above directory entry of the subdirectory
The directory information is stored in the memory card 14 when the directory is created.
The data is written to an area provided in the file area. Now, using the above hierarchical directory,
Files that are image data to be recorded are stored in sub directories.
When registering above, first, the operation switch shown in FIG.
The image file is operated by operating the MD switch 11f in the group 11.
Create a directory to secure the file recording area.
You. And the directory location to access the file
