Method for displaying contents in mobile terminal having restricted size display and mobile terminal

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal, and more particularly, to a method and apparatus for viewing a content not displayed on one screen by using a limited small screen of the portable terminal.

BACKGROUND With the development of the electronic industry, portable terminals such as portable communication devices and information devices are widely used. For example, devices such as mobile phones and PDAs are examples. However, the size of the screen mounted on the portable terminal is also limited, thereby providing visual information using the limited screen size.

Of course, it is possible to reduce the inconvenience by processing the information to fit the screen size and display a lot, for example, when displaying a drawing such as a blueprint to reduce the size of the drawing to fit the screen size can not recognize the contents of the drawing Cases may occur. In this case, if the drawing is displayed on the screen of the portable terminal without being reduced in size, the display may be divided or displayed only in part by the extent that can be displayed on the screen. This is very inconvenient, and depending on what is displayed, you may not know its appearance properly.

In other words, if the size of an image or document to be displayed on the limited size screen of the portable terminal is large, the format must be converted or displayed only to fit the screen size of the portable terminal. There is a problem that the target you want to see properly through the portable terminal.

The technical problem to be solved by the present invention is to solve the above problems, by using a terminal including a limited size screen, such as a portable terminal, the content that cannot be displayed on one screen is not changed in a separate format or split screen It is to provide a method and terminal that can be seen even if not.

According to the present invention for solving the other technical problem, a portable terminal for displaying a content including a predetermined screen configuration through a limited size screen, display the content including a predetermined screen configuration through a limited size screen A portable terminal including a portable telephone and a PDA, the portable terminal comprising: a content acquisition unit storing the entire contents to be displayed or received through a predetermined communication means; A displacement detection unit for detecting a movement displacement of the terminal in order for a user to view another area of the entire content when a partial area of the content acquisition unit is displayed on the screen; And a screen controller configured to display a partial region of the content acquisition unit on the screen of the terminal, and determine another partial region of the entire content located in correspondence with the displacement detected by the displacement detection unit to display through the screen of the terminal. Characterized in that it comprises a.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a method of displaying content using a terminal having a limited size screen according to the present invention.

Through this method of displaying content including a predetermined screen configuration on a limited size screen of a portable terminal including a portable telephone and a PDA, the screen of the terminal is displayed among all contents of a predetermined screen configuration to be displayed through the terminal. Display partial content of the area corresponding to the size of the screen through the step (100), the user using the terminal to detect the movement displacement of the terminal to move the terminal to view a different area from the displayed content of the entire content In operation 110, the partial content of another area located in correspondence with the displacement detected in operation 110 is displayed on the screen of the terminal.

FIG. 2 is a detailed flowchart illustrating step 100 of FIG. 1. The 100 steps. Set the coordinates of the entire area where the content having the predetermined screen configuration is to be displayed (step 102), set the coordinates of the partial content area to be displayed on the screen according to the size and resolution of the screen of the terminal (step 104); The partial content area with coordinates is displayed on the screen of the terminal (step 106).

3 is a block diagram illustrating a configuration of a portable terminal displaying content including a predetermined screen configuration through a limited size screen according to the present invention.

This terminal, including a portable telephone and a PDA for displaying contents including a predetermined screen configuration through a limited sized screen, stores the entire contents to be displayed or is received through a predetermined communication means. When the partial area of the content of the content acquisition unit 200 is displayed on the screen 240, the displacement detection unit 210 and the content acquisition unit detect a displacement that moves the terminal to view another area of the entire content. A portion of the content of the 200 is displayed on the screen 240 of the terminal, and the other portion of the entire content located in response to the displacement detected by the displacement sensing unit 210 is determined to determine the screen 240 of the terminal. It includes a screen control unit 220 to display through.

And the displacement detection unit 210 includes a movement confirmation unit 230 input by the user. The movement checking unit 230 will be described in detail below.

Hereinafter, a process of executing the method of FIG. 1 using the terminal of FIG. 3 will be described in detail.

The terminal to be implemented in the present invention includes a screen for displaying contents such as text, photos, videos, etc., such as a cellular phone, a PCS phone, a GSM phone, a PDA, and the like. It can also be applied to devices. And there are so many different kinds of contents.

For example, if the content is a novel, even if text or illustrations about the content of the novel are displayed on the screen of the mobile terminal, it is already used to display a small amount on the small screen and a large amount on the large screen. to be.

However, in the case of proper editing of the page in consideration of the novel and easy to see the novel, it is impossible to view the edited page while fully grasping the contents of the text or the illustrations contained in the limited size screen of the portable terminal. This inconvenience or impossibility continues even if the screen size of the portable terminal is larger than that used now.

The present invention can provide a service that can be displayed to the user through the screen of a limited size without a separate conversion process while maintaining the screen configuration of the content as it is.

The content acquisition unit 200 stores the content to be displayed on the screen of the terminal in advance, or receives and stores it through a predetermined communication means, for example, a portable telephone network. This content will be the content the user wants to view while maintaining the format displayed on the screen as described above. Of course, the present invention can be applied to content that may be arbitrarily modified.

The contents stored in advance or received by the content acquisition unit 200 cannot be viewed all at once through the screen 240 of the terminal, and the screen controller 220 may display the contents of the terminal from the entire contents of the predetermined screen configuration to be displayed through the terminal. The partial content of the area corresponding to the size of the screen is displayed on the screen 240 (step 100).

In this case, the screen controller 220 may set the coordinates of the partial content area to be displayed on the screen according to the coordinates of the entire area where the entire content is to be displayed and the size and resolution of the screen of the terminal.

That is, step 100 sets the coordinates of the entire area where the content of the predetermined screen configuration is to be displayed (step 102), sets the coordinates of the partial content area to be displayed on the screen according to the size and resolution of the screen of the terminal ( In step 104, the coordinated partial content area is preferably displayed on the screen of the terminal (step 106).

In addition, when displaying content on the screen, the screen control unit 220 preferably includes a portion where the partial content area first displayed on the terminal screen 240 starts from the entire content.

For example, the entire content is composed of 1000 pixels horizontally and vertically, so that the starting x and y coordinates of the content are (0,0), respectively, and the screen of the terminal 240 is composed of 100 pixels each horizontally and vertically. In this case, the partial content area displayed on the terminal starts from (0,0) which is the start coordinate of the entire content.

Since the screen controller 220 has coordinate values for each part of the entire content, even if any part is displayed on the terminal screen 240, the screen controller 220 has a coordinate value or an area of coordinate values of the displayed part.

After the user sees the contents displayed on the screen of the terminal or moves the terminal to find other contents. In this case, it may be sufficient to move the terminal in your hand slightly. For example, if you want to see other parts of the newspaper while viewing only the part corresponding to the size of the screen through the screen of the terminal having the newspaper, which is a wide spread content, you can move the screen of the terminal to the corresponding area. It will be a move. That is, the display area of the screen is moved.

As such, when the user who used the terminal moves the terminal to view contents in an area different from the contents displayed on the terminal, the displacement detection unit 210 detects this (step 110).

Hereinafter, an example of the displacement detection unit 210 and its operation will be described in detail.

The displacement detection unit 210 uses a device that detects a positional movement in space, for example, an inertial measurement device such as an accelerometer or gyroscope, or a commercially available device such as an image sensor that detects relative positional movement of objects around a terminal. Can be implemented.

In the case where the displacement sensing unit 210 includes an image sensor composed of predetermined light receiving pixels, the horizontal and vertical displacements are detected in a predetermined multiple of the distance between the pixels according to the light receiving pixels of the image sensor in step 110. In addition, the content of the new area displayed on the screen in response to the displacement detected in step 120 is a content area positioned corresponding to the distance between the horizontal and vertical pixels detected by the image sensor.

An image sensor including predetermined light receiving pixels is, for example, an element such as a CMOS or CCD having a predetermined number of pixels. In order to support the following functions, the image sensor has a two-dimensional array structure that knows the position of individual pixels, and consists of an array of light receiving elements that are sensors capable of measuring color or contrast, and enables continuous image acquisition. shall.

The displacement detection unit 210 includes a reference area including unit pixels or pixel groups selected according to predetermined criteria according to shape, color, and / or contrast in the T (n) frame detected by the image sensor before the terminal is moved. And setting the coordinates of the reference area, and detecting the position of the reference area according to the predetermined reference in the T (n + 1) frame, which is the next frame detected by the image sensor after the terminal is moved, to move the reference area. The calculated displacement may be implemented to detect the moved displacement of the terminal. In addition, the displacement detection unit 210 preferably sets a reference area having a predetermined shape and the number of pixels at a predetermined position in the T (n) frame, and at the next frame T (n + 1). The mobile device is moved by searching for a comparison area having the same shape as the reference area and the number of pixels to detect the comparison area where the reference area and the color (color distribution) or contrast (contrast distribution) are the closest and calculating the displacement of the moved reference area. It may be implemented to detect a displacement.

That is, the displacement detection unit 210 selects the reference pixel in the T (n) frame and detects the position of the reference pixel in the T (n + 1) frame. The selection criteria of the reference pixel is 1) a group of pixels including feature points that can be distinguished from surrounding pixels by shape, color, contrast, and the like, or 2) a group of pixels consisting of a predetermined boundary surface and the number of pixels arbitrarily selected in the center of the frame and the like.

In addition, the screen controller 220 may update the screen of the terminal by calculating a new area of content to be displayed on the terminal screen in response to the displacement of the terminal sensed by the displacement sensing unit 210.

4 is a detailed flow diagram of a preferred embodiment of implementing steps 110 and 120. Step 110 includes the following steps 111 to 117, and step 120 includes the following steps 121 and 122.

5 is a diagram illustrating each frame and a reference region detected by the image sensor.

The displacement detection unit 210 reads the T (n) frame detected by the image sensor before the terminal is moved (step 111). Before the terminal moves, an area of 1 indicated by a dotted line and a solid line in FIG. 5 is moved. That is, the T (n) frame detected by the image sensor while viewing the currently displayed content.

In operation 112, a reference area including a unit pixel or a group of pixels selected according to a predetermined reference according to shape, color, contrast, and / or texture and a reference area of the T (n) frame is set. In the frame 1 indicated by the solid line in FIG. 5, for example, the region 10 indicated by the shape of a corner is a reference region.

The displacement detector 210 reads a T (n + 1) frame which is the next frame detected by the image sensor after the terminal is moved (step 113). That is, when the user moves the terminal to view the other part of the content that was viewed through the screen, the image sensor is also moved according to the movement to detect the area indicated by the dotted line and the solid line 2 of FIG. As a result, the area 2 indicated by the dotted line and the solid line in FIG. 2 is a T (n + 1) frame.

The displacement detection unit 210 detects in which part the reference area set in step 112 is located in the frame of T (n + 1). To this end, it applies to all the pixels or regions in the frame based on the same criteria as the reference region set in step 112 to detect a region having the same result as the previous reference region. Area 20 of the solid line 2 in FIG. 5 will be determined as the changed reference area in the T (n + 1) frame. Judging only from what is shown in the figure, in this case, the reference for determining the reference area may be in the form.

The displacement detecting unit 210 determines the new coordinates of the searched reference region in step 114.

If the previous frame and the new frame are detected by the image sensor due to the movement of the terminal, it may be complex such as limitations of the sensor itself, shaking while the user moves the terminal, instantaneous light brightness and color change, and other objects passing by. Because of the cause, even if the reference region is calculated or searched by applying the same operation condition, the search result or the calculation result for the reference region of the previous frame and the new frame will not be exactly the same. Therefore, in order to prepare for such a case, it is preferable to determine that the same reference region is used when the calculation results for the reference regions are within a certain range, that is, within a predetermined threshold.

It is determined whether the result of the reference areas is within the threshold (step 115), and predetermined exception processing is performed (step 116). The exception handling will be described later.

The displacement detecting unit 210 calculates the shifted displacement of the reference region from the coordinates before and after the reference region is moved (step 117), and detects the displacement of the terminal using the calculated displacement (step 118).

Then, the screen controller 220 calculates a new area of the content to be displayed on the terminal screen in response to the shifted displacement of the terminal (step 121), and updates the newly displayed content area on the screen of the terminal to display it to the user ( Step 122).

In the above case, when the object detected by the image sensor is an object far from the terminal or an object near, even if the displacement of the terminal is small, the far object will move relatively little. The reference area of the object will move relatively much. In other words, even when the object is far away and near, even if the moving displacement of the terminal is the same, the displacement of the new area of the content viewed on the terminal screen may be changed. To prepare for this, it is necessary to determine a new area of the content to be updated in consideration of the distance from the target object detected by the image sensor or the reference area which is part of the target object.

To this end, the distance between the reference area set in step 112 and the terminal is also measured, and in step 121, a new area of the content to be displayed on the terminal screen is calculated according to the displacement of the terminal and the distance between the reference area and the terminal. It is desirable to.

Measuring the distance between the image sensor and the target object or the reference area can be easily performed through a method such as auto focus generation of the camera. For example, the distance can be easily measured by measuring the time of returning the ultrasonic wave to the target object or by measuring the time reflected by the light source.

If the user moves the terminal while walking or moving by means of transportation according to the present invention through the terminal screen, the user must move the terminal by moving his or her hand or arm to view the contents in another area. The service according to the invention can be used appropriately. To this end, the displacement detection unit 210 includes a movement confirmation unit 230 input by the user, so that when the user moves the terminal after or through the input through the movement confirmation unit 230, other contents of the entire content may be changed. It is desirable to confirm moving the terminal to see the area.

6 briefly illustrates an example of an external appearance of a terminal to which the present invention is applied. The displacement detection unit 210 described above will normally have to be located on the opposite side of the screen 340, but is shown externally for display in the drawing (310). In the configuration of FIG. 6, the movement checking unit 330 is conveniently located at a portion where the user can easily contact the outside of the terminal 300.

In other words, when the user uses the contents according to the present invention through the terminal screen 340 and tries to view another portion of the contents, the terminal 300 is moved left and right or up and down after pressing or holding the movement checking unit 330. In this case, this is confirmed as a movement for viewing another part of the content using the present invention, which is distinguished from the daily movement, and the screen controller 220 displays another area of the content on the screen 340 according to the degree of movement of the terminal. .

The displacement detection unit 210 detects the displacement in which the terminal is moved is to detect the displacement in the horizontal and vertical directions based on the area where the content is displayed or displayed, and the screen control unit 220 detects the displacement 210. Preferably, the partial content of the new area displayed on the screen in response to the detected displacement is a content area located at the detected horizontal and vertical distances from the displayed partial content area.

That is, when the content is two-dimensionally configured, the displacement detection unit 210 is horizontally and vertically two-dimensionally based on the plane in which the content is displayed when the user moves the terminal to view another portion of the content. Detect movement of x and y coordinates

In this case, since the pixel-to-pixel resolution of the image sensor may be used as a reference, the displacement detection unit 210 may perform the horizontal and vertical displacements in a predetermined multiple of the distance between the pixels according to the pixel resolution of the image sensor. And the content of the new area displayed on the screen in response to the displacement detected by the screen controller 220 in step 120, and the distance of the unit of multiples of the detected horizontal and vertical pixel distances from the content area displayed in step 100. It is preferably a content area located at.

The above description has been described only for the horizontal and vertical x and y coordinates on the plane because it is difficult for the user to move the terminal on the correct plane, but by extending this the concept of vertical while maintaining the gist of the present invention intact The same applies to the movement of the content area in the direction of the added x, y and z coordinates. In other words, the direction in which the user moves the terminal is decomposed in the horizontal, vertical and vertical directions to move to the corresponding content, and more preferably, when the content is three-dimensionally configured.

In addition to the above-described method, a variety of displacement sensing methods may be used, and any displacement sensing method may be said to fall within the scope of the present invention as long as the gist of the present invention is maintained.

As described above, the user senses the displacement of moving the terminal and the result is transmitted to the screen control unit 220 so that the content in the area corresponding to the displacement is displayed on the screen 240 of the terminal (step 120).

If the user uses the content, the terminal may be moved quickly or too much for some reason. The corresponding method will be described.

As a result of the displacement detection unit 210 calculating the displacement of the user moving the terminal may be beyond the coordinate range of the entire content. In this case, the screen controller 220 may variously handle this as an exception situation.

One exception of the screen controller 220 may display the last part of the entire content on the screen. Or 1) determine the error situation due to the user's mistake and inform the user of the error condition and continue to service according to the present invention, or 2) determine that the user no longer wants to use the content according to the present invention. 3) If the content to be displayed is stopped or 3) the content to be displayed is composed of a plurality of pages, it is preferable to display the content of the next page on the terminal screen so as to be repeated from step 100. In order to distinguish each case, the user's selection menu may be displayed on the terminal screen to distinguish the cases of 2) and 3), and may be processed according to the user's selection.

This may also be applied to the exception processing (step 116) described in FIG. 4 so as to determine the error situation and to notify the user of the error condition.

Of course, even if the case is not exception handling, it is obvious that the user can stop the service continuation or the progress according to the user's selection through the above-described selection menu or other menus while using the content service according to the present invention.

Even when the speed at which the user moves the terminal is equal to or greater than a predetermined reference, it is preferable to respond in the same manner as described above.

Content obtained or stored through the content acquisition unit 200 will vary. For example, videos, photographic images, pictures, entertainment, text-based documents, newspaper services, and many more. In either case, the present invention can still be applied.

In this case, if the contents are stored in the content acquisition unit 200 in advance, there will be no problem. For example, when the contents are received through a mobile communication network, the usage fee depends on the contents of the contents or the size of the data constituting the contents. This can be added a lot. In particular, if the user pays a fee for the entire content corresponding to one side of the drawing, such as a large-scale blueprint, it is required to download the cost through a mobile communication network and use only a part of the actual drawing. In order to reduce such side effects, when the content acquisition unit 200 receives the content through a predetermined communication means, only a part of the entire content may be transmitted, including content of a partial region to be selectively displayed on the screen of the terminal. If the content of the new area corresponding to the movement displacement of the terminal sensed by the displacement detection unit 210 is not included in the content received by the content acquisition unit 200, the new area through the predetermined communication means. It is desirable to receive another part of the entire content including the content.

To this end, even when the content acquisition unit 200 partially receives the content through the communication network, the content acquisition unit 200 receives the size of the entire content or the coordinate values of the start and the end, and receives the information about the new area to be received again from the displacement detection unit 210. Receive the request and receive the corresponding part of the entire content and receive it again.

Through this, it is possible to receive a partial content use service and to reduce the cost burden of using the service according to the present invention.

Instead of the above-described method of detecting the displacement of the user moving the terminal to display other parts of the content, other methods may be implemented by applying the present invention as it is. For example, if the user draws to the right of the screen of the terminal using a means such as a touch pen, it is also possible to display the content which is not currently visible located on the right part of the content currently displayed on the screen of the terminal. Although not described separately, it is also possible to apply the same while keeping the gist of the present invention.
