Description

Animation method in mobile communication terminal {Animation method in a mobile phone}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal. Particularly, when a mobile communication terminal provides a theme animation on a screen, the background data is separated from the object data so that only the background screen is a data format in units of frames. By replacing part of the background frame data with object data corresponding to the position, size, pointer information, etc., it is possible to efficiently manage the storage space required for enlargement in order to achieve a long animation operation or high definition color animation operation. An animation providing method of a mobile communication terminal.

In a conventional mobile communication terminal such as a mobile phone, in order to drive one animation, image data must be prepared in a data format that can be accepted by the liquid crystal display (LCD). There must be a screen buffer that is gathered and arranged to fit the liquid crystal display (LCD) screen. Such a buffer sequentially sends image data to the liquid crystal display (LCD) so that a specific image may be displayed on the liquid crystal display (LCD).

The format of the screen buffer may vary depending on the type of LCD, but in general, the number of pixels of an LCD screen that can be expressed in 1 byte (8 bits) is 8 in black and 4 in gray color. In order to display one frame corresponding to one screen and to display one frame in 256 gray colors, this series of data generated according to the LCD format must be sequentially transmitted to the screen buffer. In this sense, animation is a collection of such a series of data arrays that are transmitted to the screen buffer, and the order of each frame is determined by a function such as a counter, and a predetermined time for each frame of the screen by a function of a timer. It is supposed to maintain the interval.

By the way, one animation moves the frame data to the screen buffer for LCD output and updates the frame data so that a different modified frame screen is displayed for each frame, so that all the frame data constituting the animation are repeatedly outputted. It is implemented by doing so. At this time, each frame data is updated to the next frame at a predetermined time period by a function such as a predetermined timer, which is a series of frames corresponding to one byte per pixel stored in the memory in one-dimensional array according to the form of the screen format. By transferring data to the screen buffer. Here, the size of the data storage location is increased in proportion to the size of the screen, the number of colors, and the number of frames. Also, the application of compression technology in the embedded environment is the driving speed of the animation in a poor processing environment such as a mobile communication terminal. Since it is a part that affects the efficiency, even if the efficiency is small, a storage space (memory) of a certain size or more is required for fast processing.

However, in a mobile communication terminal such as a conventional cellular phone as described above, the storage space is required to increase the animation operation for a long time or to drive the high-definition color animation operation. For example, to drive the animation of 256 gray, Eight or four times the memory capacity of the four gray data format is required. That is, in order to drive such high-definition animation, there is a problem that most of the memory mounted in the terminal should be allocated as the image data storage space.

Accordingly, an object of the present invention is that when the mobile communication terminal provides a theme animation on the screen, it is possible to separate the wallpaper data and the object data to display the screen of different frames by combining several objects on one background screen. The present invention provides a method for providing animation for a mobile communication terminal that can efficiently manage memory space and reduce memory capacity.

Hereinafter, an animation providing operation of a mobile communication terminal according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a mobile communication terminal according to an embodiment of the present invention.

As shown, the mobile communication terminal according to an embodiment of the present invention, the control unit 100 for controlling the overall operation of the mobile communication terminal, the display unit 200 for displaying the current state of the mobile communication terminal for the user to see In addition, the wireless signal transceiver 300 for signal processing to transmit and receive a voice signal or a message to the other party, and has a plurality of numeric keys and function keys, according to the input of each of these keys to the unique key data A key input unit 400 output to the control unit 100, a storage unit 500 for storing a program necessary for performing an operation of the mobile communication terminal, etc., and an antenna in charge of transmitting and receiving voice signals or messages talking to the other party (ANT) )

The control unit 100 controls the overall operation of the mobile communication terminal, generates and transmits the current state indication data to the display unit 200, and controls the wireless communication with the base station according to the user's communication request, in particular animation The data is processed and controlled to be displayed on the screen of the display unit 200.

The display unit 200 is a user interface device for displaying the overall current state of the mobile terminal for the user to view, and in particular, displays a phone number input by the user for a call or displays the contents of the received message. . In particular, when an animation screen such as a character downloaded from the initial screen or the hair Internet is required, the animation image information corresponding thereto is displayed so that the user can view it.

The wireless signal transmission / reception unit 300 performs overall processing for wireless signal transmission and reception between the mobile communication terminal and the base station to which the terminal is subscribed, and performs signal processing to transmit and receive voice signals, messages, hair Internet data, etc. do.

The key input unit 400 includes a plurality of numeric keys and function keys as information input means of a user, and outputs its own key data to the controller 100 according to the input of each key, thereby controlling the controller 100. It enables the user to perform the functions required by the user, for example, to perform the operation for a request for inputting a phone number, writing a message, searching for a message, playing a game, and accessing a hair Internet.

The storage unit 500 stores a program necessary for performing an overall operation of the mobile communication terminal. Accordingly, the control unit 100 requests the storage unit 500 to read the stored data or to modify the data into new data. As a result of the operation, the overall operation of the mobile communication terminal is performed. Furthermore, animation data required for the initial screen and the like and animation data downloaded online such as hair Internet are stored.

Here, each animation data consists of animation operation data for animation operation, 1 or more background image data, and image data about 10 objects or less. Since the number of objects is related to the processing speed and processing capacity of the control unit 100 for screen display, it is preferable to limit the number to 10 because it is necessary to appropriately limit the number of objects.

The operation data included in the animation data includes direction information, operation option information (movement_count), frame driving time information (interval), frame number information (frame_count), and frame object information (objects_for_1frame).

Direction is the up / down motion of the background screen, left / right motion, and fixed background in each frame to provide the option to move the background image to give the background dynamic effect with the object in each animation. Information about the back.

The movement option information (movement_count) is option information in which a movement degree of each background screen is set.

Frame drive time information (interval) is interframe drive time information set in each animation.

Frame number information (frame_count) is frame number information set in each animation.

Frame object information (objects_for_1frame) is information on various objects appearing in each frame, and includes object number information (object_count) including information on the number of objects in a frame and pointer information of a background data array. The background pointer information (back_obj_ptr) and the object information (obiects) including the pointer information of the position, size, and object image data array of each object.

The animation providing operation of the mobile communication terminal according to the embodiment of the present invention made as described above will be described in detail.

2 is a flowchart illustrating an animation providing process of a mobile communication terminal according to an embodiment of the present invention, and FIGS. 3 (a) and 3 (b) show a background screen for animation according to an embodiment of the present invention. 4 objects are shown, and the frame configuration sequence according to the embodiment of the present invention is shown in FIGS. 4 (a) to 4 (d).

As shown in FIG. 2, in the animation providing operation of the mobile communication terminal according to an embodiment of the present invention, first, when a user gives an execution command such as a file open for an animation file (S101), The controller 100 reads the corresponding animation file from the storage unit 500 and extracts operation data, background data, and object image data from predetermined animation data included in the animation file (S102). An animation file is a file which displays animation image information corresponding to it when a animation screen is needed, such as an image file that can be designated as an initial screen or an image file such as a character downloaded from the hair Internet, so that a user can view it. As described above, the operation data included in the animation data includes direction information, operation option information, frame driving time information, frame number information, and frame object information. The frame object information includes object number information, Background pointer information, and objects information.

The background data is image data for the basic background image to be used in each frame as shown in FIG. 3 (a), and the object image data is image data for objects to be used in each frame as shown in FIG. 3 (b). to be.

Next, the controller 100 of the terminal transforms the background data into an image up / down or left / right on a frame-by-frame basis based on the direction information included in the operation data, and displays the background to be displayed in each frame. Screen frame data are generated (S103). At this time, the background screen to be displayed in each frame may be different, but using the same background screen and only use the wallpaper, such as up / down, left / right operation can greatly reduce the memory, as shown in Figure 4 As shown, the same background was used.

Subsequently, the controller 100 of the terminal generates frame image data by replacing corresponding portions of the background frame data generated for each frame unit with the object image data in response to the operation data (S104). . As shown in FIG. 3, this is composed of one background screen and three objects, and as shown in FIG. 4, when the animation effect is represented by four frame images, it is displayed by the same background frame data. Each object is additionally displayed at a predetermined frame cycle time interval on the background screen.

In this way, the animation data format is formed and stored in units of frames in the conventional method, and there is a difference from that a predetermined processing device simply reads frame data stored in the memory and transfers the data to the display device.

For example, when a terminal equipped with a 256-color LCD attempts to display the theme animation in 10 frames on a 120 * 128 pixel screen, each frame image data is stored in a frame unit format as in the conventional method. In this case, 120 * 128 * 10 (153.6k) bytes of memory are required, and in order to display the animation in the above-described method according to the present invention, the amount of data of the background screen is 15k bytes and the amount of data of the object is 25k bytes. Since 40k bytes are sufficient for the data amount of 5k bytes), the animation data can be stored about four times as large as the conventional memory.

As described above, when all frame image data constituting one theme animation is generated, the control unit 100 of the terminal transmits the frame image data to the display unit 200 through a predetermined screen buffer provided in the control unit 100. The display unit 200, which is an LCD, processes the transmitted frame image data so that a corresponding animation is displayed on the screen (S105).

As described above, in the animation providing method of the mobile communication terminal according to the embodiment of the present invention, when a user gives an instruction to execute an animation file to the terminal, the terminal receives operating data, wallpaper data, and object image data from predetermined animation data. Extract, and the terminal transforms the background image data to move up / down or left / right per frame unit in response to the operation data to generate background frame data to be displayed in each frame. In response to operational data, part of the background frame data is replaced with the object image data to generate frame image data, and the frame image data is transferred to a predetermined display unit through a predetermined screen buffer to display a predetermined animation. Could It was made.

Unlike the conventional method of forming an animation data format on a frame basis, the method for providing animation of a mobile communication terminal according to the present invention as described above separates the background data and object data so that only the background screen is a data format on a frame basis. Since part of the background frame data is replaced with the object data in response to the position, size, pointer information, and the like on the screen of the object, the storage space required to be enlarged in order to lengthen the animation operation or to realize the high-definition color animation operation is made. It can be managed more efficiently and saves 4 times the animation data in the same memory as compared to the conventional method, which can save memory and by combining each object in different frames according to the designer's intention. Need anime It can achieve the effect this case there is an effect of being able to further reduce the memory.
