To this end, the control method S400 of the digital image processing apparatus according to the present invention may be a program or algorithm stored in the storage means of FIG. 2 or implemented in the form of a semiconductor chip such as firmware.

Therefore, in the method S400 of controlling the digital image processing apparatus, the same matters as those described for the digital image processing apparatus and the control apparatuses 200 and 300 will be referred to, and detailed description thereof will be omitted.

Referring to the drawings, the control method (S400) of the digital image processing apparatus includes a zoom driving signal input step (S410); Creating a first thread (S420); Generating a second thread (S430); A zoom driving end signal input step (S460); And it may have a multi-threaded termination step (S470).

In the zoom driving signal input step S410, a zoom motor driving signal is received. In the first thread generation step S420, a first thread for driving the zoom motor is generated with respect to the zoom motor driving signal. In the second thread generation step S430, a second thread is generated with respect to the zoom motor driving signal.

In the zoom driving end signal input step S460, a zoom motor driving end signal is received. In the multi-thread termination step (S470), the first thread and the second thread are terminated with respect to the zoom motor driving termination signal.

In this case, the second thread may be a thread that executes the stored user specification file. In addition, the second thread may be implemented as a first thread and a multi-thread. That is, the first thread and the second thread may be executed together in time division according to their priority.

In the present invention, it is preferable that the first thread driving the zoom motor has priority over the second thread playing the user-specified file. This is to prevent the execution of the zoom drive for the execution of the user-specified file.

On the other hand, since a large amount of control resources are required to execute the first thread for driving the zoom motor, it may not be easy to implement a multi-thread in real time with other tasks. Therefore, in the present invention, the first thread for driving the zoom motor is performed at a higher priority with respect to the second thread for driving the user-specified file, so that the multi-thread implementation can be performed in real time to smoothly operate the zoom motor. can do.

In the zoom driving signal input step S410, it may be determined whether a zoom motor driving signal is input. In addition, in the zoom driving end signal input step S460, it may be determined whether a zoom motor driving end signal is input.

On the other hand, the control method (S400) of the digital image processing apparatus is implemented as the first thread and the multi-thread, generating a third thread for performing an error check, and the first thread and the multi-thread is implemented In this case, the method may further include generating a fourth thread that performs a battery test.

In this case, in the multi-thread termination step S470, the third thread and the fourth thread may be terminated along with the first thread and the second thread with respect to the zoom motor driving termination signal. That is, if necessary, in the multi-thread termination step (S470), all threads currently running as multi-threads may be terminated together.

The second thread generation step S430 includes reading a user specified file step S432; Custom file checking step (S433); Determining a user specified file (S434); Respecifying a user specified file (S436); And a user-specified file playing step (S436).

In the step of reading a user-specified file (S432), the designated user-specified file is read. In the user specified file reproducing step (S436), the read user specified file is reproduced.

The second thread generation step S430 executes the designated user specified file when the zoom motor driving operation is performed, thereby reproducing the user specified file which may cause interest to the user. Accordingly, user convenience of the digital image processing apparatus can be improved.

In this case, the user specification file may be intuitive and interesting content using a user friendly Graphical User Interface (GUI). Thus, the user can experience emotional intimacy or enjoyment by the user-specified file played during the idle mode operation. Accordingly, the usability and usability of the product can be improved.

The user specification file may be at least one of a still image file, a video file, and a sound file. At this time, an image of one still image file is displayed or images of a plurality of still images are sequentially displayed at set time intervals, so that a user-specified file may be reproduced.

The second thread generation step S430 may include a step S431 of determining whether a user interface function is in an ON state. In this case, it is determined whether the user interface function is in an ON state, and when the user interface function is in the ON state, the user interface function performed below may be performed.

The custom interface function may be set by selection through a separately designated hot key or a button or a menu.

The user-specified file specified in the user-specified file reading step S432 may be read, and the user-specified file read in the user-specified file playback step S436 may be played back. In this case, a specific image file or a sound file may be designated as a user designation file by default. In addition, the designated user designation file may be changed to another file by user designation.

On the other hand, it is possible to determine whether there is an abnormality in the user-specified file read before performing the user-specified file reproducing step (S436), and respecify the user-specified file when there is an error in the user-specified file. To this end, the second thread generation step (S430) includes a user-specified file checking step (S433); Determining a user specified file (S434); And a user-specified file redirection step (S436).

In the user-specified file checking step (S433), it is checked whether the user-specified file is a playable file. In the user-specified file determination step (S434), it is determined whether the user-specified file is a playable file. In the user-specified file reassignment step (S435), when the user-specified file is not playable, a new file is designated as the user-specified file. In this case, after the user designation file redirection step S435 is performed, the user designation file reading step S432 may be performed.

In this case, the user-specified file determination step (S434) determines whether the user-specified file is a playable file, and if the user-specified file is a playable file, the user-specified file playback step (S436) may be performed. In addition, when the user-specified file is not playable, the user-specified file redirection step S435 may be performed.

Meanwhile, when the user-specified file execution end signal is input, the reproduction of the user-specified file may be terminated. In this case, the user-specified file reproduction end signal may be a multi-threaded end signal generated in the multi-threaded end step S470.

When the user-specified file execution end signal is input, the second thread generation step S430 may include a determination step S437 to end the reproduction of the user-specified file. In the determination step S437, it may be determined whether a user-specified file execution end signal is input.

As a result of the determination in the determination step S490, when a user-specified file execution end signal is input, the user-specified interface function according to the present invention is terminated. At this time, when the user-specified file execution end signal is not input, the user-specified file reading step S432 may be performed again.

According to the present invention, user convenience can be improved by allowing a user-friendly interface to be executed in a multithread even during other tasks.
