The present invention relates to a method for initializing an electronic device, and more particularly, to a method for selectively initializing only a module to be initialized in an electronic device having a plurality of modules.

 The electronic device is composed of a plurality of modules. For example, a digital video camera is composed of a camera module and a VCR (Video Cassette Recorder) module. The camera module receives an image signal from the lens through AE (Auto Exposure), AF (Auto Focus), and AWB (Auto White Balance). And the VCR module is responsible for storing and playing back the video taken by the camera module. When power is applied to the photographing apparatus, each module performs a basic operation. The operation is determined according to initialization data stored in the EEPROM.

EEPROM (Electrically Erasable Programmable Read Only Memory), a kind of nonvolatile memory, does not delete data already stored even when the power supply is interrupted. It is a nonvolatile memory that can be erased to rewrite new data. Therefore, Y pyrom is widely used in devices and devices that need to rewrite data or programs.

At present, electronic devices are becoming more versatile and are becoming more and more intelligent. Therefore, the amount of initialization data required for the basic operation of each module is increasing. Therefore, each initialization data is not input separately, but is formatted into an entire data table and stored in the EEPROM.

During the process of developing an electronic device, the developer may replace the initialization data table of each module with a new data table or return to the previous data table. Currently, a method of collectively initializing all modules included in an electronic device is used as an initialization method of the electronic device. The time required for initialization of the electronic device is initialized as described above. This longer problem occurs.

In addition, in the electronic device composed of the first module and the second module, if the developer of the first module initializes the electronic device in the process of observing the change of the electronic device while changing only the data of the first module, the first module and All of the second modules are initialized. Therefore, when the data for the second module is set according to a function and environment other than the basic operation, the inconvenience of having to reset the data of the second module after the initialization step occurs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a method for selectively initializing only a module to be initialized in an electronic device having a plurality of modules.

According to the present invention for achieving the above object, an initialization method of an electronic device for initializing the plurality of modules according to the initialization data by reading initialization data for the plurality of modules from a nonvolatile memory (a) detecting an initialization command for each module for initializing any one of the plurality of modules, and (b) selecting the module to be initialized when detecting the initialization command for each module in step (a). (C) reading initialization data of the module selected in the step (b) from the nonvolatile memory, and (d) the selected module according to the initialization data read in the step (c). Initializing.

The method of initializing the electronic device may include backing up the data currently set for the plurality of modules to the nonvolatile memory, and if a restore command for initializing the plurality of modules is detected according to the backed up data. The method may further include reading the backed up data from the volatile memory and initializing the plurality of modules according to the backed up data.

In addition, step (b) may include (b1) displaying a list of the plurality of modules and (b2) selecting any one of the displayed plurality of modules.

Hereinafter, with reference to the drawings will be described the present invention in more detail.

1 is a block diagram of a digital video camera as an example of an electronic device. Referring to FIG. 1, the digital video camera includes a camera unit 100, a VCR (Video Cassette Recorder) unit 200, a controller 300, an EEPROM 400, a key input unit 510, and a display character generator 520. , And a liquid crystal display (LCD) 530.

The camera unit 100 photoelectrically converts an optical image formed through a camera lens into an electrical signal in a charged coupled device (CCD), and then AE (Auto Exposure), AF (Auto Focus), and AWB (Auto White Balance). Signal processing is performed according to the conditions of.

The VCR unit 200 receives an image signal processed by the camera unit 100, stores the image signal on a tape (not shown), and displays the image data stored on the tape on the LCD 530.

The EEPROM 400 stores initialization data for the camera unit 100 and the VCR unit 200. The initialization data of each module is standardized and stored in the data table, and the data table for each module is stored in the EEPROM 400. The storage space to be stored is preset.

2 is a diagram illustrating a situation in which a data table is stored in the EEPROM 400 of FIG. 1. Referring to FIG. 2, the initialization data table of the camera unit 100 is stored at addresses 0X01 to 0X10 of the EEPROM 400, and the initialization data table of the VCR unit 200 is stored at addresses 0X11 to 0X20. Data tables can be changed by the developer during the development phase of the system.

On the other hand, addresses 0X21 to 0X40 are places where data tables of functions and environments currently set for the camera unit 100 and the VCR unit 200 are stored, and addresses 0X41 to 0X60 are just before the initialization of the system. The data table for the function and environment currently set for the 100 and the VCR unit 200 is backed up. That is, if the developer has received an initialization command of the photographing apparatus, the current setting data table of the photographing apparatus stored at addresses 0X21 to 0X40 of the EEPROM 400 is backed up to addresses 0X41 to 0X60 of the EEPROM 400.

In addition, version 1 data tables are stored at 0X61 to 0X80, version 2 data tables are stored at 0X81 to 0XA0, and version 3 data tables are stored at 0XA1 to 0XC0.

Referring to FIG. 1, the key input unit 510 displays a 'menu key' for displaying a menu item and a cursor in addition to the keys used to operate the camera unit 100 and the VCR 200 unit. A direction key for moving the cursor on the menu screen and a confirmation key for designating a menu item on which the cursor is displayed are provided.

The display character generator 520 functions to generate a specific character, a menu item, and a cursor at a specific position of the LCD 530 under the control of the controller 300.

The LCD 530 also displays the images received from the camera unit 100 and the VCR unit 200 in addition to displaying the characters, menu items, and cursors generated by the display character generator 520.

The controller 300 controls the display character generator 520 such that a character, a menu, and the like corresponding to the signal received from the key input unit 510 are displayed on the LCD 530. In addition to the function of controlling the overall operation of the camera unit 100 and the VCR unit 200, the controller 300 receives a system initialization command from a developer and correspondingly responds to the camera unit 100 and / or the VCR unit 200. ) To initialize the function.

Meanwhile, the developer may instruct the digital video camera to be initialized using the key input unit 510, the display character generator 520, and the LCD 530.

 Hereinafter, a process of inputting an initialization command by a developer and a process of initializing a digital video camera by the controller 300 will be described in detail.

When the developer first presses the 'menu key' provided in the key input unit 510, the initial menu screen is displayed on the LCD 530 as shown in FIG. 3A. The developer can set the operation environment of the camera unit 100 and the VCR unit 200 by selecting 'camera unit environment setting' or 'VCR unit environment setting', and the data on the environment set by the developer is EEPROM ( 400 at 0X21 to 0X40.

As shown in FIG. 3A, when the developer places the cursor on 'system initialization' and presses the 'OK' using the arrow keys, as shown in FIG. 3B, 'all' and 'modules' as dependent menus. Four menu items, 'other version' and 'restore' are displayed. On the other hand, '▶' indicates that there is a subordinate menu for the menu item. The control unit 300 reads out the current setting data table stored in addresses 0X21 to 0X40 of the EEPROM 400 and backs it up to addresses 0X41 to 0X60 of the EEPROM 400. This is intended to restore the digital video camera to the settings it had before the initialization if the developer mistakenly set the wrong data.

If the developer selects 'All' among the above menu items, the controller 300 reads out initialization data tables of the camera unit 100 and the VCR unit 200 stored at addresses 0X01 to 0X20 of the EEPROM 400, Accordingly, the camera unit 100 and the VCR unit 200 are initialized.

Meanwhile, when the developer places the cursor on the module using the arrow keys and presses the confirmation key, as shown in FIG. 3C, the camera unit and the VCR unit, which are submenus of the module, are displayed. Are displayed together. When the developer selects the 'camera unit' among the displayed menu items, the controller 300 reads out the initialization data table of the camera unit 100 stored at addresses 0X01 to 0X10 of the EEPROM 400, and accordingly the camera unit 100 ).

In addition, as shown in FIG. 3D, when the developer places the cursor on the VCR unit and presses the OK key using the direction key, the controller 300 is located at 0X11 to 0X20 of the EEPROM 400. The stored VCR unit 200 initialization data table is read, and the VCR unit 200 is initialized accordingly.

On the other hand, if the developer selects the 'other version' in the menu screen shown in Figure 3b, as shown in Figure 3e, 'version 1', 'version 2' and 'version 3' submenus of the 'other version' Is displayed together. If the developer selects 'Version 1' among the displayed menu items, the controller 300 selects 0X61 to 0X80 of the EEPROM 400, and selects 'Version 2' to address 0X81 to 0XA0 of the EEPROM 400. If 'version 3' is selected, addresses 0XA1 to 0XC0 of the EEPROM 400 are read, respectively, and the camera unit 100 and the VCR unit 200 are initialized accordingly.

When the developer initializes the digital video camera according to the above three methods and accidentally sets the wrong data or determines that the data that was set before the initialization is necessary, the command to reinitialize the data set before the initialization If 'Restore' is selected, the controller 300 reads the backup data table stored at 0X41 to 0X60 of the EEPROM 400, and initializes the camera unit 100 and the VCR unit 200 accordingly.

4 is a flowchart provided to explain a method for initializing a digital video camera according to an embodiment of the present invention. Referring to FIG. 4, when the developer selects the 'system initialization' mode for initializing the digital video camera, the controller 300 first reads the current setting data table stored in addresses 0X21 to 0X40 of the EEPROM 400. (READ) and backs up to addresses 0X41 to 0X60 of the EEPROM 400 (S810).

In addition, the controller 300 may perform an 'all initialization' command for initializing all of the digital video cameras from the key input unit 510, an 'module initialization' command for initializing any one of a plurality of modules constituting the digital video camera, One of a 'initialize to another version' command for initializing the digital video camera to any one of a plurality of initialization data versions, and a 'restore' command for initializing the digital video camera to data backed up before the initialization is performed ( S820, S831, S841).

If the 'all initialization' command is detected in step S820, the control unit 300 reads (READ) the initialization data tables stored in the camera unit and the VCR unit stored in addresses 0X01 to 0X20 of the EEPROM 400 (S851). The camera unit 100 and the VCR unit 200 are initialized (S861).

In operation S831, when a module initialization command is detected, the developer selects one of the camera unit 100 and the VCR unit 200 through the key input unit 510 (S833). When the camera unit 100 is selected in operation S833, the controller 300 reads the camera unit initialization data table stored in addresses 0X01 to 0X10 of the EEPROM 400 (S852), and accordingly, the camera unit ( Initialize 100) (S862). On the other hand, if the VCR unit 200 is selected in step S833, the control unit 300 reads (READ) the VCR unit initialization data table stored at addresses 0X11 to 0X20 of the EEPROM 400 (S853), and accordingly VCR. The unit 200 is initialized (S863).

On the other hand, if the 'initialize to another version' command is detected in step S841, the developer selects any one of the version 1, version 2, and version 3 through the key input unit (510) (S843, S845). When version 1 is selected in step S843, the controller 300 reads (READ) the version 1 data table stored at addresses 0X61 to 0X80 of the EEPROM 400 (S854), and accordingly, the camera unit 100 and the VCR. Initializing the unit 200 (S864), if version 2 is selected in step S845, the control unit 300 reads (READ) the version 2 data table stored at 0X81 to 0XA0 of the EEPROM 400 (S855). In this case, the camera unit 100 and the VCR unit 200 are initialized (S865), and if version 3 is selected in step S845, the controller 300 stores the version stored in addresses 0XA1 to 0XC0 of the EEPROM 400. 3 The data table is read (READ) (S856), and the camera unit 100 and the VCR unit 200 are initialized accordingly (S866).

On the other hand, if the 'restore' command is detected in step S841, the control unit 300 reads (READ) the backup data table stored at 0X41 to 0X60 of the EEPROM 400 (S857), and accordingly the camera unit 100 ) And the VCR unit 200 are initialized (S867).

As described above, according to the present invention, in an electronic device having a plurality of modules, only the module to be initialized can be selectively initialized, and the module that does not need to be initialized can not be initialized. Convenience can be provided in the process of developing the device.
