Afterwards, a preview of the GIF animation or the original image will be generated as a single GIF animation file upon user request. The generated GIF animation file is stored in a new file format in a memory or animation storage unit. Here, assuming that the selected original image is two, the process of converting the GIF animation file is as follows.

That is, when the user selects the first original image and the second original image, the portable terminal first converts the first original image into a bitmap file and edits and overlays the converted file. After applying it, convert it to the GIF file of the first frame. Subsequently, the second original image is converted into a bitmap file, and after editing, overlay, etc. are applied to the converted file, the second original image is converted into a GIF file of a second frame. Thereafter, the converted first and second frames are converted into a single GIF file to generate a completed GIF animation file.

Referring to FIG. 3, if an animation function is requested from the user in the standby mode 301 (303), determining the requested animation function (305); and if the result of the determination is a request for generating a new GIF animation file, Displaying (307) an original image selection screen; checking (309) whether or not an image selection is completed from a user after displaying the selection screen; and displaying the list of the selected original images when the selection is completed; Checking whether the GIF animation file is generated after the display (313); and generating a GIF animation file by encoding the selected original images when generating the GIF animation file (315). And storing the file generated after the file generation in the animation storage unit (317), and the checking result G If the IF animation file is not generated, driving the image editing application (325), and after driving the application, characterized in that it comprises a step (327) for performing an image editing processing routine. In addition, when the determination of the existing animation file is requested as a result of the determination of step 305, displaying the existing GIF animation file list stored in the animation storage unit (321), and selecting the GIF animation file to be edited by the user after displaying the list. It is checked whether or not (323), and as a result, if the file selection is completed, driving the image editing application (325), and after driving the application, and performs the image editing processing routine (327). .

Looking at the overall process for generating and managing animation in a portable terminal according to an embodiment of the present invention using the above configuration in more detail as follows.

First, the portable terminal determines the requested function when the animation production is requested from the user through a key input unit. As a result, if the function request for producing a new GIF animation file, and extracts the image files stored in the memory and provides an image selection screen through the display. Thereafter, when the user completes selection of image files for producing a GIF animation by using a key input unit or the like, a file list screen of the selected one or more images is provided. Subsequently, a GIF animation file is generated using the selected one or more images. At this time, encoding of each original image data is performed. Thereafter, each encoded image is synthesized to generate a new GIF animation file, and the generated GIF animation file is stored in the animation storage unit.

Meanwhile, if the input signal requested by the user is a request for editing an existing animation file, the GIF animation files stored in the animation storage unit are extracted, and then the extracted GIF animation file list is displayed. At this time, when a GIF animation file to be edited is selected, the image path of the selected file is traced to extract an image, and at the same time, an image editing application is driven. Thereafter, the image editing application performs an editing processing routine of the selected image.

Hereinafter, a process of generating the GIF animation file according to FIG. 3 and a process for shortening the time required for generating the animation will be described with reference to FIGS. 4 and 5.

4 is a diagram illustrating a schematic embodiment to explain an animation generation process in a portable terminal according to the present invention. FIG. 5 is a diagram for explaining an encoding procedure according to the present invention. FIG. 5 is a view illustrating a comparison between a general GIF animation image generation procedure and a GIF animation image generation procedure improved by the present invention.

Referring to FIG. 4, when an animation image generation is required from a user, steps 401 and 403 of adding an image file to be added for animation generation are performed, and the read file is decoded according to the execution. Determining a file format (405), and if the file format decoded as a result of the determination is a format other than a GIF format, decoding the read file and converting the file into a bitmap file 407, encoding the converted bitmap file to convert the encoded bitmap file into a GIF format of one frame, and converting the encoded bitmap file into a GIF format in one frame; After the step of converting to the GIF format of step 409, checking whether the read file undergoing the procedure is the first image file to be added for generating an animation (411); If the file read is the first file, applying (write) to all frames using the default color palette and application extension to the resulting GIF animation file (413); If the file read in step 411 is not the first file or after step 413, applying (writing) a graphic control extension (Graphic Control Extension) to the finally created GIF animation file; After the application, performing step 417 of writing the image data of the read file to be added to the finally created GIF animation file, and checking whether there is a further image file to be added after writing the image data ( 419), and if the next file to be added is checked, the processing routine goes to the last file. Repeating, if the next image file to be added as a result of the check does not exist, recognizing that the read file is the last file to be added and performing end-of-file writing on the finally created GIF animation file; When the end-of-file writing is performed on the GIF animation file, a complete GIF animation is generated (423).

This configuration will be described below with reference to FIG. 5.

Referring to FIG. 5, FIG. 5 is a diagram illustrating a comparison of a general GIF animation image generation procedure and a GIF animation image generation procedure improved by the present invention.

In this case, the present invention is to reduce the encoding required to generate the animation through the processing in steps 407 to 417 in FIG. 5 described above. In other words, for example, in the symbian codec, a color palette writing process for generating an animation file, as shown in FIG. 5, is applied in the entire process of searching for each of the added image data. That is, if you look briefly, it creates one frame by writing header-> Color Palette-> Image Data and then adds the header to the next added image. )-> Color Palette (Local Color Palette)-> Image Data It has the encoding method to create the next frame (2 frames) by writing.

However, all GIF files created using the Symbian codec have the same palette. Accordingly, the present invention proposes an encoding scheme as shown in FIG. 4 to apply to all frames using the first basic palette used in the Symbian codec.

That is, in the process of converting image files to GIF files by generating one frame, it is not necessary to have a local color palette in the GIF animation file according to the characteristics of all having the same color palette. Therefore, a method of omitting the local color palette writing process according to retrieval of the portion, that is, the next image data, is proposed when encoding an animation. This reduces the amount of writing to the final result file, so that when you retrieve the next image data, you can skip that portion to improve animation encoding speed and, as a result, reduce the time required to create the animation. have.

As described above, the GIF animation encoding speed improvement method proposed in the present invention can shorten the overall time required to generate one animation file combining a plurality of images, thereby reducing the time wasted on generating the animation to the user. It can provide services that can be minimized.

Hereinafter, the image editing processing routine according to FIG. 3 will be described in detail with reference to FIG. 6.

First, when the editing mode is the preview 611, the portable terminal drives the preview application in conjunction with the controller and the animation processing unit, and then previews the animation to be generated by the selected original image.

Next, when the editing mode is the image add / delete 631, the portable terminal drives the image add / delete application in cooperation with the controller and the animation processor. In this case, in the case of adding an image, a list of original image files is displayed so that a new original image can be added. In case of deleting an image, a list of original images selected for animation generation is displayed to select an image to be deleted. To delete it.

Next, when the editing mode is the animation effect 651, the portable terminal runs an effect application for giving an effect such as a background of a GIF animation file in association with an animation processing unit, and subsequently interlocks with a memory to produce a background effect image. To display the effect selection screen. In this case, the display screen may be displayed in the form of a thumbnail or a detailed view, but the present invention is not limited thereto. Subsequently, when the user selects the background effect through the provided selection screen, the animation processor recognizes the selected background effect, overlays the recognized background effect on the GIF animation file, and then displays the GIF animation overlaid on the background effect. Display. Subsequently, after confirming the application of the background effect from the user, when the input signal through the key input unit is received from the user, the selected background effect and the GIF animation are synthesized, and one completed GIF animation is generated and stored in the animation storage unit.

Next, when the editing mode is the animation setting 671, the portable terminal provides a setting screen to the user by driving an application that can set an animation delay time or an operation order of the original image. Since the processing in the setting editing mode is described below with reference to FIG. 5, a detailed description thereof will be omitted herein.

Next, when the editing mode is image editing 691, the portable terminal drives an image editing application to extract original image data applied to the GIF animation from an animation storage unit, and to edit the extracted original image data. To provide. Here, the image editing is editing for each original image applied to the GIF animation file, and means adjusting the original image such as adjusting the resolution or contrast of each original image. However, the present invention is not limited thereto, and it will be apparent that the present invention can be applied to all corresponding applications.

Hereinafter, an animation delay time or an image order setting process according to the animation setting according to FIG. 6 will be described with reference to FIG. 7.

7 is a diagram illustrating a processing process according to animation setting in image editing according to the present invention.

Referring to FIG. 7, when an animation setting editing mode for a GIF animation is selected by a user, the animation processing unit recognizes this and drives an animation setting application (701), and the type of the requested setting after driving the application. In response to determining the delay time setting (703), and requesting the delay time value input in cooperation with the display unit (705), and if the delay time value is input (707) in response to the input request, the input delay In the step 709 of applying the time to the GIF animation file, and in the case of changing the order of image operation as a result of determining the type of the requested setting (711), an operation through the original image list of the animation to be generated in conjunction with the display unit and the animation storage unit. Displaying a sequence setting screen (713), and setting the operation sequence after the display is completed ( In step 715, the process of applying the set operation sequence result is made.

Looking at the GIF animation setting process according to an embodiment of the present invention through the above configuration in more detail as follows.

First, when a detailed setting operation of a GIF animation is requested from a user through a key input unit or the like, the animation processing unit detects this and provides a user interface for setting the animation through the animation detail setting application. Then, the user selects a GIF animation file for detailed setting through the user interface. At this time, when selecting the animation file, the portable terminal searches the animation storage unit to extract the GIF animation file requested from the user and provide it to the user.

On the other hand, when the selected GIF animation file is provided, the user adjusts the delay time according to the animation execution for the animation file, that is, the time taken for switching between frames in each original image. In this case, the user may set the delay time by inputting a delay value desired by the user, such as 1 second, 2 seconds, 3 seconds, or the like, or may perform setting through random application. In addition, the operation order of the original image according to the execution of the animation, that is, the operation order in which each original image is sequentially switched may be arbitrarily changed. For example, in the case where there are three original images constituting the GIF animation, that is, the image 1, the image 2, and the image 3, the image motion sequence of the first GIF animation is "Image 1-> Image 2-> Image 3". Suppose that the image is displayed repeatedly in the order of "1". Then, the user can change the order of the user arbitrarily like "Image2-> Image1-> Image3-> Image2". However, the present invention is not limited thereto. For example, the operation order may be set to be sequentially performed according to the order selected when the image to be generated from the initial image file list is selected, or the operation may be set to be randomly performed on all selected images. have.

Next, when the series of animation settings as described above is completed, the completed animation setting information, that is, the changed delay time value or the image operation order change information is applied to the GIF animation and then updated to the animation storage unit.

Meanwhile, in the present exemplary embodiment as described above, the present invention is illustrated as being a service for a still image, but the present invention is not limited thereto. For example, the original image data has been described for a still image. Even in the case of an animation file in the form of GIF, the above case may be applied in the same manner or an application interface and a process thereof may be further provided.
