The present invention relates to a portable terminal capable of classifying and capturing a photographing mode according to a pattern form of touching a touch screen, instead of a method of photographing a digital photograph by pressing a shutter outside the portable terminal and a photographing method thereof.

The development of touch screen technology is coupled with the rapid development of portable terminals, and a touch screen portable terminal capable of being conveniently operated by a user by hand is becoming popular in the market. A portable terminal using a touch screen is utilized in a form that a user can see, feel, and touch beyond a mobile phone function, and contributes greatly to satisfying the emotional part of the user. BACKGROUND OF THE INVENTION [0002] A camera of a touch screen type portable terminal which is widely used at present is generally configured to take a picture using a shooting button (shutter) on the side surface of the terminal (see Fig. 1). 1 is a method generally used in commercially available digital cameras, and does not actively utilize the advantages of the touch screen, and presses the shutter at the time of photographing. In this case, since the shutter is small, the operation is inconvenient, and the portable terminal may be easily shaken during the operation.

In addition, there is a portable terminal designed to utilize a method (see FIG. 2), ie, a touch method, for photographing through a touch of a specific portion of the touch screen. However, even in such a portable terminal, it is inconvenient to additionally create a menu for setting various shooting modes since the user is required to simply photograph a specific portion.

Accordingly, the present invention has been made in view of the above circumstances, and actively utilizes the method of touching the screen using the advantages of the touch screen, but provides various shooting modes according to the pattern of the user's touch. It is an object of the present invention to provide a portable terminal and a photographing method thereof capable of improving the accuracy of photographing by shaking the portable terminal.

According to a first aspect of the present invention for achieving the above object, the camera is provided with a camera function unit including a touch screen and a shooting button and the camera is supported according to a form of inputting a touch pattern on the touch screen without operating the shooting button. As a touch type portable terminal that implements various types of shooting modes,

In order to implement the form of inputting the touch pattern, the screen arrangement area is divided into screens of left, center, and right areas based on the screen of the touch screen.

The portable terminal divides the left area into a zoom in / out mode and a square button area, the center area into a display area for displaying images before and after camera shooting, and the right area into a rectangular touch pattern area to touch. Is provided.

The arrangement of the screen arrangement area may change the configuration of the screen screen from side to side according to the setting of the left-handed / right-handed mode.

The determination of the right-handed mode and the left-handed mode may be set in advance in the user interface setting menu before executing the camera mode, and may be specified using the menu selection button in the camera execution mode.

In addition, it is preferable to support various types of shooting modes such as general shooting, night mode shooting, video shooting, panorama shooting, continuous mode shooting, etc. according to a method of manipulating the rectangular touch pattern area located at the right side.

In addition, the above-described various types of shooting modes include general shooting in which the touch pattern is touched for at least 1 second, night mode shooting in which the upper part of the rectangle is photographed by moving the finger to the lower part of the rectangle while pressing the upper part of the rectangle. Continuous mode shooting where you hold down the bottom part and then push it up to the upper part, then shoot video by touching the touch pattern twice in succession, and touch the diagonal pattern of the rectangle on the touch pattern from top to bottom diagonally It is preferable that it is panorama photography etc. which image by touching.

In addition, it is preferable to further form a scroll-in zoom-out / out button area in the left area in order to utilize the zoom-in / out function when taking a picture.

In addition, the zoom in / out function may be implemented by touching the small bar in the center of the scroll button and moving up to zoom in and down to zoom out.

According to a second aspect of the invention,

In addition, when photographing is completed, it is preferable to further include the step of retrieving the previous picture by touching the area where the photographed picture is output.

In addition, it is preferable to prevent the malfunction of the camera program that may occur when each touch part is touched by determining the priority of each touch detection in the order of menu button> zoom in / out> shooting by touch pattern.

According to the present invention, by providing a variety of shooting modes according to the pattern that the user touches, it is possible to improve the convenience of the operation and the accuracy of shooting through the shaking of the portable terminal.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

The present invention is a general portable terminal cellular phone (cellular phone), personal communication system (PCS: Personal Communication System), PDA (PDA: Personal Data Assistant), IMT-2000 (International Mobile Telecommunication-2000) , Digital cameras, digital camcorders, and the like.

First, a camera program is executed in the UI (User Interface) of the portable terminal. In this case, a screen of the type shown in FIG. 3 is displayed on the touch screen integrated portable terminal. The arrangement of the screens may be roughly divided into screens of the left, center, and right regions based on the touch screen screen. Specifically, the left area is a zoom in / out mode and a square button area 3, the center area is a display area 2 displaying images before and after camera shooting, and finally the right area is a rectangular pattern to be touched. Recognition box area 1. The layout of the screen can be changed in the camera setting menu of the UI. The above arrangement is based on the right-handed mode, and in the case of changing the left-handed mode to the left-handed mode, the configuration of the screen screen may be changed from left to right. In the following, description will be continued on the basis of the right-handed mode.

The rectangular touch pattern region 1 located on the right side supports various types of photographing modes according to a method of operation. In this case, the shooting mode includes general shooting, night mode shooting, video shooting, panorama shooting, continuous mode shooting, and the like. For example, when the touch pattern is touched for more than 1 second (FIG. 4A), a picture is taken. On the other hand, when the finger is moved to the lower part of the rectangle while the upper part of the rectangle of the touch pattern is pressed (Fig. 4 (b)), night mode photography in which the aperture is opened for a relatively long time is taken. In addition, if you hold down the upper part of the rectangle and then lower it to the upper part again, continuous mode shooting is performed, and if you touch the touch pattern twice consecutively (as if you double-click the mouse), video recording is performed again. Repeating the pressing operation twice in succession stops the video recording (Fig. 4 (c)). If the diagonals of the rectangles are touched in the downward direction from the top to the diagonal lines as shown in the x shape (Fig. 4 (d)), panorama shooting is performed. In addition, for functions performed by other than the pattern, such as determining the picture resolution or manipulating the lighting mode, touch the square button 4 at the top of the left screen to display each function on the screen in a tree form. By selecting a function desired by the user, it can be performed.

In order to utilize the zoom in / out function when taking a picture, the scroll button 5 at the end of the left screen is used. Touching the small bar in the center of the scroll up to zoom in and down to zoom out, you can easily implement the zoom in / out function. Since the zoom in / out function can be implemented at the left end, the middle scroll button-shaped rectangle is pushed up to zoom in and down to zoom out.

At this time, the degree of zooming in / out is recognized by the scroll center bar as a kind of origin coordinate to calculate the ascending or descending distance to indicate the size of the zooming in / out to the zoom motor of the camera unit. To save a picture, touch the square button (4; Fig. 3) at the top of the left screen twice in a row while shooting is completed, and an input window for inputting a picture name and whether to save the picture appears. You can perform the save. Before the picture is saved, if the picture is taken, you can touch the picture and move it to the left or right to see the pictures before the picture. It also has the ability to easily compare with the current picture. The touched part becomes a kind of origin coordinate. When moving to the left regardless of up or down for the first touch, the most recently stored picture is displayed. On the contrary, the latest stored picture is displayed on the screen. When touch is executed again, the next picture (left to right) and the previous picture (right to left) are displayed. In order to smoothly take a picture through the touch, when the mobile terminal is turned upside down, the camera should be placed in a place where both hands holding the mobile terminal cannot reach. This may vary depending on the type of terminal, but a camera phone that is currently commercially available, for example, the camera lens is located in the middle of the reach of both hands when the portable terminal is upside down, usually open and close The cover takes the form of protecting the camera lens (7; see FIG. 3 (b)). The opening lid can be operated automatically or manually when in camera mode.

As described above, unlike the conventional operation method, by classifying the shooting mode by using the touch pattern without performing unnecessary operations such as changing the shooting mode by manipulating the menu, it is possible to facilitate the photographing. . In addition, by maximizing the advantages of the touch screen and reducing external buttons, a simple and neat image can be displayed in terms of appearance design.

5 is a diagram illustrating a hardware configuration of a general portable terminal according to the present invention. As shown in FIG. 5, in the present invention, as a program or data storage device, a ROM (Read Only Memory) 41, a RAM (Random Access Memory) 42, and a flash ROM (flash Read Only Memory), as in the configuration of a general portable terminal, are used. 43) and the like. The ROM 41 stores microcodes of programs and various reference data for processing and control of the control unit (MPU) 20. On the other hand, the RAM 42 stores temporary data generated during execution of various programs. When the program is temporarily executed, the data in the ROM 41 or the flash ROM 43 is loaded into the RAM 42, and the control unit 20 processes this. The flash ROM 43 stores various updateable storage data such as an outgoing message and a received message.

When a user of a general portable terminal executes a camera command, the controller 20 displays a camera photographing mode on a screen. Execution and termination of instructions is via a user interface program, which is stored in ROM 41 in the form of software. The touch sensors distributed on the screen perform a function corresponding to the input regardless of the arrangement area when performing the general function, and recognize the touch operation input to the divided screen area as shown in FIG. 3 when the camera mode is executed. Thus, the corresponding operation is performed. At this time, the screen division is in charge of the camera execution process of the user interface program. The touch pattern area 1 or the square button 4 represented on the screen is an area that substantially receives an input related to the execution of the camera function. The touch pattern area 1 or the square button 4 receives a form input by a touch sensor located below the area. 20).

Next, a method of distinguishing the form in which the touch pattern is input will be described. In order to recognize one touch, two touches, touch down from top, touch down from top and back up, touch x draws in a rectangle, etc. on the touch pattern area (1), the program is based on the first touched coordinates. Recognize it by coordinates. Thereafter, the direction in which the user moves the finger is tracked, and if the pattern form is 80% or more as compared with the ideal input pattern form stored in the ROM 41, the controller 20 accepts the input as an actual input. Instructs the camera module unit 30 to shoot in the shooting mode. On the other hand, in the scroll type region 5, the state where the scroll button is pressed is regarded as the origin coordinate, and input to the remaining area is not accepted. If the user moves the scroll button in the up or down direction while pressing the scroll button, the zoom in / out is executed by the distance moved from the origin coordinate. In order to distinguish the degree of zoom in / out, how much to control the zoom in / out control motor (zoom motor) 31 according to the distance to which the finger is moved is numerically stored in the ROM 41 in the form of a table, and the control unit 20 Instructs the camera module 30 to operate the zoom-in / out control motor 31 by the corresponding value by comparing the designated zoom-in / out degree with the value of the table. In addition, the square button (4) on the left side displays a menu related to the camera shooting function in a tree shape, and sets the screen on which the menu is output to a high priority (2) or a zoom-in / out mode in which the captured image appears. Even if overlapped with the area 5, the touch on the menu is preferentially recognized. In addition, it performs a function such as a save button used to save the captured image. Lastly, in the middle area 2 where the image before and after shooting is located, the point touched by the user in the whole area is recognized as the origin coordinate, and when it is touched to the left or right from this point, the pattern is ROM (41). Compare to the pattern stored in). At this time, if it is considered appropriate to the pattern to move from left to right, or right to left, a picture already stored in the flash ROM 43 is loaded and displayed on the touch screen, and the picture stored according to each pattern may be a previous picture. It may be the first or last picture taken.

The determination of the right-handed mode and the left-handed mode can be set in advance in the user interface setting menu before executing the camera mode, and can be specified in the camera running mode by using the menu selection button.

6 is a flow chart showing the overall sequence of program execution. Based on this flowchart, a photographing method of a portable terminal capable of classifying and photographing photographing modes using the touch pattern of the present invention will be described below.

First, the camera execution menu is executed (step S1). Before executing this camera execution menu, a user interface program is used to determine whether to execute the camera program in right-handed mode or left-handed mode (steps S2 and S4). Thereafter, when the camera mode is executed (step S3), a touch is detected for three types of inputs (steps S5 and S6). The priority of each touch detection is a sequence of menu button> zoom in> shooting by touch pattern (Fig. 7). This is to prevent malfunction of the camera program by processing the touch parts at the same time according to their priority. If a touch is detected, first check whether the highest priority menu button is executed (step S7), and if the menu button is not executed, check whether zoom in / out is executed (step S8), and then zoom to the next. If the in / out is not executed, the procedure proceeds to the step of confirming the touch pattern input (step S9). If a part irrelevant to these specific functions is touched, that is, the menu button execution is not confirmed in step S7, the zoom in / out execution is not confirmed in step S8, and the touch pattern input is not confirmed in step S9. Will return to the standby state.

On the other hand, when the execution of the menu button is confirmed in step S7, the menu button is executed (step S10) and the process returns to the standby state. If execution of zoom in / out is confirmed in step S8, camera zoom in / out is executed (step S11), and the process returns to the standby state. If the input of the touch pattern is confirmed in step S9, the photographing mode (touch pattern method shown in Fig. 4) according to the input touch pattern is executed, and the photographing is completed (step S13).

When shooting is completed in step S13, it is checked whether or not to save (step S14). If the storage of the picture is confirmed, the picture is saved (step S15), and it is checked whether the camera mode is finished (step S16). When the user executes a command to end the camera mode, the camera execution program ends. On the other hand, if the picture is not stored, it returns to the standby state. The present invention also has a function of bringing up the previous picture by touching the area 6 (the video picture scroll area of FIG. 3 (a)) in which the photographed picture is output when shooting is completed, but the flowchart of FIG. Did not describe.

The present invention can be expected to utilize a new field of a portable terminal by providing various photographing modes according to a pattern type that a user touches without operating an external shutter in a portable terminal possessed by most modern adults.
