Description

Screen display device and method {APPARATUS AND METHOD FOR DISPLAYING SCREEN}

The present invention relates to a screen display device and a method, and more particularly to a screen display device and method that can display a strong asymmetric material on the screen so that the user can easily control.

Recently, a lot of data having a longer horizontal or vertical length than a screen horizontal or vertical length of a display device has been generated. In particular, many of these data are asymmetrical shapes, that is, data that is significantly longer than the width (or length) of the data displayed on the screen. Examples of such data include long time-exposure satellite images, database tables, and the like. When asymmetrical data is displayed on the screen using a conventional data reduction method that proportionally reduces the horizontal and vertical lengths of the data, the shorter length becomes difficult to display on the screen because it changes to the minimum size that cannot be controlled. But you can't easily jump to a specific piece of material you want. The larger the size of the material, the smaller the display device becomes.

Accordingly, an object of the present invention is to provide a screen display device and a method for displaying a highly asymmetric material on a screen and allowing a user to easily move to a desired location of the data.

The height of the frame is longer than the width of the frame, and if the ratio of the frame divided by the length of the frame is greater than the data ratio divided by the length of the material by the length of the frame, the length of the frame is the length of the frame. And the width of the frame is calculated by multiplying the length of the frame by the data rate, and if the frame rate is not greater than the data rate, the width of the frame is equal to the width of the frame and the length of the frame is the width of the frame. It can be calculated by multiplying with the data ratio.

If the length of the frame is not longer than the width of the frame, and the frame ratio of the frame length divided by the width of the frame is greater than the data ratio of the length of the material divided by the width of the material, the width of the frame is the width of the frame. Is equal to the width and the height of the frame is calculated by multiplying the width of the frame by the data rate, and if the frame rate is not greater than the data rate, the length of the frame is equal to the length of the frame and the width of the frame is equal to the length of the frame. It can be calculated by multiplying the length by the data ratio.

If the width and length of the material or the ratio of length and width is smaller than a predetermined threshold, the frame may be classified as asymmetrical, otherwise it may be classified as symmetrical.

When the frame is asymmetric, the size of the frame may be set to the same size as the frame.

When the frame is symmetrical, the ratio of the width and length of the frame may be the same as the ratio of the width and length of the material.

The height of the frame is longer than the width of the frame, and if the ratio of the frame divided by the length of the frame is greater than the data ratio divided by the length of the material by the length of the frame, the length of the frame is the length of the frame. And the width of the frame is calculated by multiplying the length of the frame by the data rate, and if the frame rate is not greater than the data rate, the width of the frame is equal to the width of the frame and the length of the frame is the width of the frame.

3 to 8 will be described in more detail with respect to the screen display method according to an embodiment of the present invention.

3 is a flowchart illustrating a process of calculating a frame in a screen display method according to an embodiment of the present invention.

When the operation is started and the user selects the data to be displayed on the screen, the frame calculator 112 receives the selected data (S310) and calculates the horizontal (w) and vertical (h) lengths of the data. Also receives an input variable from the user (S320). The input variables include the width (dw) and length (dh) length and minimum size (thr) of the frame. At least one of the input variables may not be input from the user or may be substituted with a predetermined value.

The frame calculator 112 calculates the size of the symmetrical frame using the width (w) and length (h) of the data and the length (dw) and length (dh) of the frame (S330).

FIG. 4 is a flowchart for explaining a method of calculating the symmetric frame size shown in FIG. 3.

Referring to FIG. 4, the frame calculator 112 receives the horizontal (w) and vertical (h) of the data and the horizontal (dw) and vertical (dh) lengths of the frame (S400), and the horizontal (dw) of the frame. Vertical (dh) is compared (S410). As a result, the frame rate (dr = dw / dh) and the data rate (r = w / h) are calculated when the frame width (dw) is smaller than the length (dh) (S420). dr = dh / dw) and data ratio (r = h / w) are calculated (S460).

After the step S420, the frame rate dr and the data rate r are compared (S430). If the frame rate dr is greater than the data rate r, the horizontal magnification is maintained (S440). (S450). That is, in step S440, the width fw of the frame is calculated as dh * r, and the height of the frame fh is equal to the height of the frame dh, and in step S450, the width fw of the frame is calculated. The width of the frame (fh) is calculated as dw / r.

After the step S460, the frame rate dr and the data rate r are compared (S470). If the frame rate dr is greater than the data rate r, the vertical magnification is maintained (S480). (S490). That is, in step S480, the frame width fw is equal to the frame width dw, and the frame height fh is calculated as dw * r, and in step S490, the frame width fw is dh /. Calculate with r and leave the frame's height (fh) equal to the frame's height (dh).

An example of the symmetric frame size that can be calculated is described with reference to FIGS. 5 and 6.

FIG. 5 is a schematic diagram of normalizing a frame size and a data size to explain a screen display method according to an embodiment of the present invention, and FIG. 6 is a frame and data to explain a screen display method according to an embodiment of the present invention. A schematic diagram showing the relationship of

First, as shown in FIG. 5, the size of the frame and the data is divided into the longest and the longest, and normalized. The long axis is then 1 and the short axis is less than or equal to 1.

From the perspective of magnification after this normalization process, the size relationship between the frame and the data is divided into the cases shown in FIG. First, when normalized data enters into a normalized frame as shown in (a) and (b) of FIG. Corresponding to FIG. 6A corresponds to the frame calculated in step S440, and corresponding to FIG. 6B corresponds to the frame calculated in step S480. At this time, the rectangle shown by the solid line in FIG. 6 is a normalized frame, and the rectangle indicated by a dotted line and hatched is a normalized data.

When normalized data does not fit in the normalized frame as shown in (c) to (f) of FIG. 6, the axis size of the data corresponding to the frame shortening is equal to the size of the frame shortened, and the size of the remaining axes of the data is Create a frame by zooming out to fit the ratio of. Corresponding to (c) and (e) of FIG. 6 is a frame calculated in step S450, and corresponding to (d) and (f) of FIG. 6 is a frame calculated in step S490.

Referring back to FIG. 3, whether the size of the symmetrical frame calculated in step S330 is a symmetrically controllable size, that is, the width fw and the length fh of the frame calculated in step S330 are both the minimum size ( thr) is greater than (S340).

As a result, if any one of the width (fw) and the length (fh) of the frame is smaller than the minimum size (thr), it is determined as an asymmetric frame, and the asymmetric frame size is calculated to be equal to the size of the input frame (S350), and the calculation mode Set to asymmetric mode. That is, in this case, the width (fw) of the asymmetrical frame is equal to the width (dw) of the frame, and the height (fh) of the asymmetrical frame is the same as the height (dh) of the frame. .

On the other hand, if it is determined that the size can be controlled symmetrically in step S340, the frame size calculated in step S330 is used as it is and the calculation mode is set to the symmetric mode.

When the size of the asymmetric frame or the symmetrical frame is calculated, the ratio of the data and the frame is calculated (S360). That is, the aspect ratio (rw) is calculated by dividing the width (w) of the data by the frame width (fw), and the vertical ratio (rh) is calculated by dividing the length (h) of the data by the frame length (fh). Thereafter, output variables such as frame size (fw, fh), aspect ratio (rw, rh), and calculation mode are output (S370).

7 and 8 will be described a method of matching the coordinates of the frame and the coordinates of the data so that the user can move to the desired portion of the data.

FIG. 7 is a flowchart illustrating coordinate transformation in a screen display method according to an exemplary embodiment of the present invention, and FIG. 8 is an exemplary diagram of coordinate transformation illustrated in FIG. 7.

As illustrated in FIG. 7, when the user inputs a frame coordinate P (x, y) corresponding to a portion of the material to be displayed on the screen by a mouse click or a touch method (S710), the coordinate converter 114 The coordinate Q (x) is calculated by multiplying the frame coordinate P (x) by the aspect ratio rw, and the coordinate Q (y) is calculated by multiplying the frame coordinate P (y) by the vertical ratio rh (S720). Then, a clamp function is performed on the coordinate Q (x, y) (S730). That is, if the value of the coordinate Q (x) is larger than the width (w) of the data or the value of the coordinate Q (y) is larger than the length (h) of the data, an overflow has occurred, and also frame coordinates and data If the origin of the coordinate is referred to as the upper left corner, if the value of the coordinate Q becomes negative, an underflow has occurred, which may occur when a user clicks or touches the frame outside the size of the frame due to a mistake of the user. In this case, the coordinate corresponding to the position of the actual data that is closest to the coordinate Q (x, y) is output as the data coordinate R (x, y) (S740). When no overflow or underflow occurs, the coordinate Q (x, y) becomes the data coordinate R (x, y).

Referring to FIG. 8, the frame coordinate P1 inside the frame corresponds to the data coordinate R1 inside the data according to the horizontal ratio rw and the vertical ratio rh. In contrast, frame coordinates P2, P3, and P4, although coordinates outside the frame, correspond to data coordinates R2, R3, and R4 that are closest to each coordinate, so that if the user inadvertently indicates a coordinate beyond the allowable range, Part may be displayed.

The controller 110 displays the data and the frame on the screen of the display unit 130 using the frame size calculated by the frame calculator 112 and the data coordinates R (x, y) calculated by the coordinate converter 114.
