Thereafter, the portable terminal continues to count the number of shots based on the shooting information (in particular, the number of shots) read in step 315 (step 321). In step 321, the count of the number of picture taking is the remaining number of pictures except for the number of pictures read in step 315 from the number of pictures preset by the user.

For example, when the number of pictures is set to 10 in the process of setting a photo shooting condition as illustrated in FIG. 1, and the number of pictures taken in steps 303 to 307 of FIG. 3 is four, the picture is taken in step 317. When the resumption resumes, the portable terminal counts the number of pictures taken in step 321 from five.

Thereafter, the portable terminal determines whether the number of preset pictures and the number of counted pictures are the same (step 323). If it is determined that the number of preset pictures and the number of counted pictures are not the same, the portable terminal returns to step 303 to step 303 to step Perform 323

Alternatively, if it is determined in step 323 that the preset number of pictures and the number of counted pictures are the same, the portable terminal reads the temporarily stored picture and generates an image file in a predetermined image format (step 325).

Here, the portable terminal may read out the pictures stored in steps 311 and 319 to generate an image file, and the image file may be a predetermined image format capable of continuously displaying a plurality of pictures taken according to a predetermined picture shooting condition. (For example, GIF, SWF, or SIS format).

In addition, the image file is generated such that each photographed picture can be displayed according to a preset picture display time. Alternatively, in another embodiment of the present invention, it may be generated as a separate image file having the same characteristics as the image file in addition to the image file format.

The portable terminal then stores the generated image file (step 327).

As shown in FIG. 3, in the image file generation method of the portable terminal according to another embodiment of the present invention, by adding a pause function during photo shooting, a user desires a subject without being restricted by the location or time at which the photo was taken. After shooting, you can make it into an image file.

For example, it can be used when you want to create a single image file that can be taken continuously after taking a picture of three work sites at each of the remote work sites A, B, and C. .

Specifically, if the user wants to take two pictures per work site, select '6 pictures' in the 'number of pictures' item and '2 seconds' in the 'photo display time setting' item as shown in FIG. After selecting, pause two pictures at the 'A' site with the portable terminal, resume shooting at the 'B' site, take two pictures and pause, and finally take a picture at the 'C' site. After taking the last two photos and taking all six photos, it is possible to generate a predetermined image format that can continuously display the six photos taken. When the image file generated as described above is reproduced, six photographs are continuously displayed at preset two second intervals.

1 to 3, in the method of generating an image file of a portable terminal according to an embodiment of the present invention, a user sets a continuous picture shooting condition (picture number setting and picture display time setting) in advance, When the portable terminal counts the number of photographed pictures and equals the set number of pictures, the portable terminal may store the photographed pictures as one predetermined image file representing a continuous image.

Therefore, by generating a plurality of pictures taken in real time as a single image file at the time of shooting, it is possible to continuously view the pictures taken without a separate editing process, thereby improving the ease of use.
