Description

How to save image data and voice data in personal portable device

The present invention relates to a personal portable device such as a personal information mobile terminal, and more particularly, to a method of storing image data such as a photo and voice data in a personal portable device.

In general, digital cameras or personal portable devices (eg, personal information mobile terminals) that can be used by attaching a camera simply provide a function of capturing a certain scene, storing the image on a recording medium, and viewing the stored image later. Therefore, users must remember the contents of each scene or make notes in order to edit the shots. In addition, since only image data excluding audio data is stored in the recording medium, there is a disadvantage in that the emotion at the time of photographing cannot be restored when the captured scene is reproduced later. In particular, if the image is taken in the background of a magnificent natural environment, such as waterfalls, the above-mentioned disadvantages will become even more significant.

Accordingly, an object of the present invention is to provide a method of storing image data as well as voice data in a personal portable device having a camera attached to a predetermined scene.

Still another object of the present invention is to provide a method of storing image data and voice data that can select and record arbitrary image data captured by the personal information mobile terminal and record and store voice data corresponding thereto.

The present invention for achieving the above object has a video signal processing unit for converting and outputting the image signal captured by the camera to the image data, and a voice signal processing unit for compressing and converting the audio signal input through the microphone into digital data In the image data and voice data storage method of a personal portable device,

A first process of addressing and storing the image data output from the image signal processor in a memory;

A second process of displaying image data stored in the memory on a screen display unit at an arbitrary size;

And a third process of selecting arbitrary image data among the displayed image data and storing the voice data output from the voice signal processor at an address corresponding to the selected image data.

Hereinafter, an operation according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a system configuration diagram in which a personal digital assistant (PDA) 100 and a server 200 which is a data processing unit are connected according to an exemplary embodiment of the present invention. Referring to FIG. 1, the camera 10 of the personal information mobile terminal 100 includes a CCD for converting an optical signal of a subject input through a lens unit into a captured image signal and outputting the captured image signal. The image signal processor 20 samples the captured image signal output from the camera 10, adjusts the automatic gain, and converts the image signal into digital data. The image data converted into digital data as described above is then stored in the memory 40 under the control of the controller 30.

The controller 30 includes a ROM in which a control program as shown in FIG. 2 is stored and a RAM for temporarily storing data generated during a control operation of the mobile terminal. To control. For example, the controller 30 reads out image data stored in the memory 40 and displays the image data on the screen display unit 70, and receives and stores voice data corresponding to the selected image data according to a user's selection. The memory 40 stores image data and voice data under the control of the controller 30. The microphone 50 amplifies a voice signal from the outside and outputs the amplified voice signal to the voice signal processor 60. The voice signal processor 60 outputs compressed voice data by digitally converting the voice signal. Such voice data is stored in the memory 40 under the control of the controller 30.

The screen display unit 70 displays the display data input from the control unit 30 on the touch screen. For example, the screen display unit 70 displays a menu for selecting functions that can be supported by the personal information mobile terminal, or displays the fact of the storage state of the voice data when selecting specific image data to the outside. The key input unit 80 includes a plurality of function keys and buttons (power buttons) for operating a personal information mobile terminal, and generates key data according to a key operation and outputs them to the controller 30. The interface unit 90 interfaces the transmission and reception of image data and voice data between the personal information mobile terminal 100 and the server 200. The server 200 processes the image data and the audio data uploaded from the personal information mobile terminal 100 and outputs them to the display unit and the speaker or edits them according to an editing algorithm.

FIG. 2 is a flowchart illustrating an image and audio data storing process according to an exemplary embodiment of the present invention. FIG. 3 is a view showing an initial display of FIG. 2 and FIG. 4 is a view showing an image list of FIG. It is shown. FIG. 5 is a diagram showing an example of a recording state of FIG. 2, and FIG. 6 is a diagram showing an example of a voice storage fact display of FIG.

Hereinafter, an operation of storing image data and voice data in the personal information mobile terminal 100 will be described in detail with reference to FIGS. 2 to 6.

First, when power is applied to the personal information mobile terminal, the controller 30 performs a series of initialization operations and displays the initial screen on the screen display unit 70 in step 210. At this time, the screen displayed on the screen display unit 70 is shown as shown in FIG. On the left side of the screen display unit 70 are shift keys ↑, ↓ and a select and cancel key for selecting any one of the displayed functions and image data to be described later. After displaying the initial screen, the controller 30 proceeds to step 220 and checks whether there is an image view selection by the user. If a function other than the selection of the inspection result image is selected, the control unit 30 performs other functions such as a camera function, an upload function, a battery check function, and the like in response to the program.

If the user selects an image view in step 220, the controller 30 proceeds to step 230 and displays an image list on the screen display unit 70 as shown in FIG. 4. At this time, the image list displayed on the screen display unit 70 becomes image data already captured by the camera function and stored in the memory 40. Although only six image lists are shown in FIG. 4, when there are six or more image data stored in the memory 40, the user confirms all the image data stored in the memory 40 using the shift keys ↑ and ↓. Can be. At the bottom of the image list display screen, a message "Please select the desired image" is displayed to the user. Therefore, if there is a selection of specific image data in step 240, the controller 30 proceeds to step 250 and checks whether sound data corresponding to the selected image data is stored in step 240.

If the audio data corresponding to the selected image data is stored in step 250, the control unit 30 proceeds to step 260 and displays a message on the screen display unit 70 to delete the stored contents. After that, the process proceeds to step 270 to check whether there is a selection or cancel input from the screen display unit 70. In the following description, the selection is to affirm the stored content deletion request message, and the cancellation is to be interpreted to mean to cancel the stored content deletion request message. Therefore, if the cancel key is input in step 270, the control unit 30 returns to step 230, and if the selection key is input, the control unit 30 proceeds to step 280 and deletes the stored voice data and returns to step 230.

On the other hand, if the audio data corresponding to the selected image data is not stored as a result of the 250 step, the control unit 30 displays a message, "Do you want to select the sound recording" on the screen display unit 70 before proceeding to step 290 After that, proceed to step 290. In step 290, if there is a selection key input from the screen display unit 70, that is, if there is a sound recording selection, the controller 30 proceeds to step 300. The voice data input to the microphone 50 and signal-processed and compressed by the voice signal processor 60 is stored in the memory 40 in step 300. While storing the voice data input as described above, the mobile terminal displays the external status in step 310 that the current mobile terminal is in the recording state. The screen display indicating the recording state is as shown in FIG. In FIG. 5, the display of the image data currently being recorded, the recording time (5.2 seconds), the remaining memory capacity, and the recordable time accordingly are displayed together, so that the user can store sufficient voice data while checking the recordable time.

As described above, if there is a cancellation selection while selecting the image data already recorded and recording the voice corresponding thereto, the controller 30 ends the storage of the voice data and proceeds to step 330 to record the voice. Voice recording is displayed on the image data as shown in FIG. 6. Accordingly, the user can recognize that the voice data is stored together with the image data already taken.

By the above-described operation, the user can store the voice data corresponding to the captured image data in the memory 40, after which the user selects the upload function of the image data and the voice data stored in the memory 40 on the initial screen. Can be sent to the server 200 which is a data processor for editing or confirmation.

Meanwhile, in the exemplary embodiment of the present invention, a series of commands such as selection of image data and storage of voice data are input using a touch screen, but the image data is selected by providing a plurality of function keys on the key input unit provided without any modification. Alternatively, a specific function may be selected to perform the processing flow operation as shown in FIG. It is also possible to simultaneously store image data and voice data. Therefore, the scope of the invention should not be defined by the described embodiments, but should be defined by the equivalent of claims and claims.

As described above, the present invention can store not only the scene but also the surrounding sound or voice data by the user at the time of taking a random scene, so that there is an advantage of bringing a vivid impression (or emotion) and a sense of reality at the time of shooting even after elapse of time. .
