In addition, since the component which attached | subjected the same code | symbol in embodiment performs the same operation | movement, description may be abbreviate | omitted again.

(Embodiment 1)
In this embodiment, when there are two or more selectable graphics in the area designated by the finger, a graphic processing apparatus that automatically enlarges the area including the designated area will be described.

  Also, in the present embodiment, a graphic processing device with different magnifications according to the graphic existing in the region will be described. In particular, a graphic processing device that enlarges a region until one graphic exists in the region will be described.

  Further, in the present embodiment, a graphic processing device that automatically detects an area designated by a finger will be described.

  In the present embodiment, a graphic processing apparatus that displays an enlarged area in a window different from the original screen (window) will be described. In such a case, a graphic processing apparatus will be described in which the separate window is displayed avoiding the designated area, or other graphic is not displayed or is displayed in an area where there are few other graphics. Here, the window is a concept including the entire screen.

  FIG. 1 is a block diagram of a graphic processing apparatus 1 according to the present embodiment. The graphic processing apparatus 1 includes a graphic information storage unit 11, a reception unit 12, a graphic display unit 13, an area detection unit 14, a determination unit 15, an enlargement unit 16, and a drawing unit 17. The graphic processing device 1 is, for example, a so-called CAD system in which a graphic is displayed on a touch panel. Further, the graphic processing device 1 may be considered to include a touch panel display, or may be considered to include a touch panel display as an information output destination of the graphic processing device 1. The touch panel may be of any type, such as a projection-type capacitance method, a surface-type capacitance method, an electromagnetic induction method, a surface acoustic wave method, an infrared method, a surface acoustic wave method, and a resistive film method.

  The graphic information storage unit 11 can store two or more graphic information. The graphic information is information relating to the graphic, and has position information indicating the display position of the graphic. Here, the figure is a line, a triangle, a rectangle, a circle, an ellipse, a bolt, a nut, or the like, but also includes parts constituting the figure. The parts that make up the figure are line segments and points that make up the figure. The points constituting the figure are, for example, singular points. A singular point is a predetermined specific point corresponding to a figure. For example, the start and end points of a line segment, the center point of a circle, a 90-degree point around a circle, the start and end points of an arc, a line segment, a circle , Intersections formed by arcs, and the like. The position information is coordinate information (x, y) of a point on a figure (rectangular vertex, etc.) or a point important for an expression (equation etc.) representing the figure (center of circle, two focal points of ellipse, etc.) Coordinate information (x, y). The graphic information includes, for example, graphic related information and position information. The figure-related information has a type identifier for identifying the type of figure and an attribute of the figure. The type identifier may be information indicating the type of figure (for example, triangle, circle, point, line, etc.), or may be a function name or a method name for drawing a figure. The figure attributes include, for example, the figure size, line type, line color, and background color. In addition, the parts which comprise a figure are synonymous with a part of figure.

  The graphic information storage unit 11 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium. The graphic information in the graphic information storage unit 11 is usually information input by a user via an input device, but the process of storing the graphic information is not limited. For example, graphic information may be stored in the graphic information storage unit 11 via a recording medium, and graphic information transmitted via a communication line or the like is stored in the graphic information storage unit 11. May be.

  The accepting unit 12 accepts an instruction by touch. The instruction by touch here is usually an instruction to select a figure. The reception unit 12 also receives a drawing instruction for drawing, a display instruction for displaying a figure, and the like. In addition, the receiving unit 12 may receive other instructions and information. Here, accepting is usually accepting information input from an input device such as a touch panel. However, the reception of drawing instructions and the like is a concept including reception of information transmitted via a wired or wireless communication line, reception of information read from a recording medium such as an optical disk, a magnetic disk, and a semiconductor memory. Suppose there is. The instruction by touch is usually a finger instruction. Moreover, you may catch that the instruction | indication by a touch is synonymous with a touch.

  The figure display unit 13 displays two or more figures at a display position on the touch panel display. The graphic display unit 13 displays a graphic at the position indicated by the positional information included in the graphic information corresponding to the graphic. In addition, for example, when the receiving unit 12 receives a display instruction, the graphic display unit 13 displays a graphic corresponding to the display instruction.

  The graphic display unit 13 may be considered to include a display device or not. The graphic display unit 13 can be realized by display device driver software, or display device driver software and a display device. Here, the display device may be a touch panel alone or may be considered to include a touch panel and another display (for example, a liquid crystal display).

  The area detection unit 14 detects an instruction area that is a touched area. For example, when the touch panel is a projection-type capacitive touch panel, the region detection unit 14 acquires the change in the capacitance of the electrodes from the two vertical and horizontal electrode rows, and there is a change in the capacitance more than a predetermined value. A region that is a region and continuous in position is determined. Such an area is referred to as an instruction area.

  In addition, the area | region detection part 14 may acquire the fixed instruction | indication area | region containing the said coordinate information, when the coordinate information of one touched is acquired. In such a case, the area detection unit 14 holds information on the size of the designated area in advance. Further, the shape of the indication area may be rectangular or circular. The instruction area here may be fixed or dynamically determined. The case where the pointing area is dynamically determined means that the finger and the ground plane of the touch panel display become the pointing area.

  The area detection unit 14 can be usually realized by an MPU, a memory, or the like. The processing procedure of the area detection unit 14 is usually realized by software, and the software is recorded on a recording medium such as a hard disk. However, it may be realized by hardware (dedicated circuit).

  When the receiving unit 12 receives an instruction, the determining unit 15 determines whether or not there are more than a predetermined number of selectable figures in the specified area that is the specified area.

  More specifically, the determination unit 15 usually determines the display range of the graphic from position information included in each of the two or more pieces of graphic information in the graphic information storage unit 11, and the display range and the instruction region overlap. In some cases, it is determined that the graphic indicated by the graphic information exists in the designated area. Then, the determination unit 15 determines whether there are more than a predetermined number of selectable figures in the designated area.

  Usually, the determination unit 15 calculates from the instruction area and the graphic information, and determines whether or not all or a part of the graphic corresponding to the graphic information exists in the instruction area. More specifically, the determination unit 15 includes, for example, an expression representing a graphic obtained from the graphic information in the graphic information storage unit 11 (for example, an equation such as a straight line, a circle, or an ellipse specified by the type of graphic), By solving simultaneous equations and inequalities consisting of the instruction area or the expression representing the boundary line of the instruction area, it is determined whether or not all or a part of the figure corresponding to the graphic information exists in the instruction area. Further, when determining whether or not one or more singular points are present in the designated area, the determining unit 15 first determines whether or not all or part of the figure is present in the designated area. Only a singular point of a figure for which it is judged that all or a part of the figure exists in the designated area may be determined. Note that a technique for determining whether or not a figure is included in a certain area (in this case, in the designated area) is a known technique, and thus further detailed description is omitted.

  In addition, the instruction | indication area | region here may be fixed and may be determined dynamically. Further, the predetermined number is usually two, but may be three or more. The selectable graphic is usually a graphic displayed on the display. However, even if the graphic is displayed on the display, the graphic managed as inactive by the management means (not shown) may be excluded from the selection target. The determination unit 15 can usually be realized by an MPU, a memory, or the like. The processing procedure of the determination unit 15 is usually realized by software, and the software is recorded on a recording medium such as a hard disk. However, it may be realized by hardware (dedicated circuit).

  The enlargement unit 16 enlarges and displays at least the instruction area when the determination unit 15 determines that there are more than a predetermined number of selectable figures in the instruction area. Here, the magnification to be enlarged may be a fixed magnification or may be dynamically changed. Further, the enlargement of the instruction area may be an enlargement of only the instruction area, a wider area including the instruction area, or an enlargement of the entire screen or window including the instruction area. good. The designated area is a designated area and includes a figure on the designation. Moreover, the area | region containing a figure is an area | region where the figure is displayed.

  Further, the enlargement unit 16 may enlarge and display the designated area at different magnifications depending on the graphic existing in the designated area. “According to the figure” may be the number of figures, the type of figure, or the like.

  Further, the enlargement unit 16 may enlarge and display the designated area at a magnification that allows only one figure to exist in the designated area. For example, the enlargement unit 16 repeats enlargement at a fixed magnification until only one figure exists in the designated area, and ends the enlargement when determining that only one figure exists in the designated area.

  Further, it is preferable that the enlargement unit 16 enlarges and displays the area including the instruction area in a window different from the window in which the graphic display unit 13 displays each of the two or more figures.

  Further, it is preferable that the enlargement unit 16 displays another window at a position that does not overlap the designated area in the window displayed by the graphic display unit 13.

  Furthermore, it is preferable that the enlargement unit 16 displays another window at a position where the graphic displayed by the graphic display unit 13 is not displayed.

  Note that the enlargement unit 16 usually displays an instruction area on the touch panel. However, the enlargement unit 16 may display an enlarged instruction area or the like on another display device that is not the designated touch panel. The enlargement unit 16 can be usually realized by an MPU, a memory, or the like. The processing procedure of the enlargement unit 16 is usually realized by software, and the software is recorded on a recording medium such as a hard disk. However, it may be realized by hardware (dedicated circuit).

  When the receiving unit 12 receives a drawing instruction, the drawing unit 17 performs drawing according to the drawing instruction. The drawing unit 17 usually displays the drawn graphic on the graphic display unit 13 and accumulates graphic information corresponding to the graphic in the graphic information storage unit 11. When the receiving unit 12 receives a selection instruction for one graphic, the drawing unit 17 may perform a process of setting a graphic corresponding to the selection instruction as a current graphic. In addition, the figure which the drawing part 17 draws does not ask | require, and the drawing method does not ask | require. Since the drawing unit 17 can be realized by a known technique, a detailed description thereof is omitted. The drawing unit 17 can usually be realized by an MPU, a memory, or the like. The processing procedure of the drawing unit 17 is usually realized by software, and the software is recorded on a recording medium such as a hard disk. However, it may be realized by hardware (dedicated circuit).

  Next, the operation of the graphic processing apparatus 1 will be described using the flowchart of FIG. Here, the operation until the graphic processing apparatus 1 selects a graphic will be mainly described.

  (Step S201) The receiving unit 12 determines whether an instruction has been received. If an instruction is accepted, the process goes to step S202, and if no instruction is accepted, the process returns to step S201.

  (Step S202) The region detection unit 14 determines whether or not the instruction received in Step S201 is a graphic selection instruction. If it is a figure selection instruction, the process goes to step S203, and if it is not a figure selection instruction, the process goes to step S208. The selection instruction is usually a touch on the touch panel with a finger.

  (Step S203) The area detection unit 14 acquires the touched instruction area. The area detection process for acquiring the instruction area will be described with reference to the flowchart of FIG.

  (Step S204) The determination unit 15 determines whether there are more than a predetermined number of selectable figures in the designated area acquired in step S203. Such determination processing will be described with reference to the flowchart of FIG.

  (Step S205) The enlargement unit 16 determines whether or not the determination result in Step S204 is a determination result that there are more than a predetermined number of selectable figures in the designated area. If there are more than a predetermined number of selectable figures, go to step S206, otherwise go to step S207.

  (Step S206) The enlargement unit 16 enlarges and displays at least the designated area, and returns to step S201. Such processing is called enlargement processing. The enlargement process will be described with reference to the flowchart of FIG.

  (Step S207) The drawing unit 17 or means (not shown) (not shown) selects a graphic existing in the designated area. If no graphic exists in the designated area, nothing is processed in this step. The process returns to step S201.

  (Step S208) A unit or the like (not shown) performs processing according to the instruction. When the instruction is a display instruction, the graphic display unit 13 displays graphic information corresponding to the instruction. The process returns to step S201. In the flowchart of FIG. 2, the process is terminated by powering off or a process termination interrupt.

  In step S208, when the instruction received in step S201 is a drawing instruction, the drawing unit 17 performs a drawing process according to the drawing instruction. Note that the graphic selection in step S207 may be a process constituting a part of the drawing process.

  In the flowchart of FIG. 2, the process performed using the selected graphic after the graphic is selected does not matter. Such processing includes, for example, drawing processing, editing processing, display change processing (enlargement, color change, etc.), and the like.

  Next, the area detection process in step S203 will be described with reference to the flowchart of FIG.

  (Step S301) The area detection unit 14 substitutes 1 for a counter i.

  (Step S302) The region detection unit 14 determines whether or not the i-th vertical region on the touch panel exists. If the i-th vertical region exists, the process goes to step S303, and if it does not exist, the process returns to the upper process.

  (Step S303) The area detection unit 14 substitutes 1 for a counter j.

  (Step S304) The area detection unit 14 determines whether or not the jth horizontal area on the touch panel exists. If the j-th horizontal region exists, the process goes to step S305, and if not, the process goes to step S309.

  (Step S305) The region detection unit 14 acquires a change in capacitance in the vertical region i and the horizontal region j (referred to as (i, j)).

  (Step S306) The region detection unit 14 determines whether or not the change in capacitance is greater than or equal to a threshold value. If the change in capacitance is equal to or greater than the threshold value, the process proceeds to step S307, and if the change in capacitance is not equal to or greater than the threshold value, the process proceeds to step S308.

  (Step S307) The area detection unit 14 acquires an instruction area including the area (i, j). Here, for a region adjacent to the region (i, j), the region detection unit 14 acquires a change in capacitance, and if the change in capacitance is equal to or greater than a threshold value, the adjacent detection unit 14 The area to be added is added to the designated area. And the area | region detection part 14 repeats this process.

  (Step S308) The area detection unit 14 increments the counter j by 1, and returns to step S304.

  (Step S309) The area detection unit 14 increments the counter i by 1, and returns to step S302.

  In the flowchart of FIG. 3, the touch panel is assumed to be, for example, a projection-type capacitance method. However, the touch panel may be a surface-type capacitance method, an electromagnetic induction method, a surface acoustic wave method, or the like. The area detection unit 14 acquires an instruction area by a method according to the touch panel method.

  In the flowchart of FIG. 3, the area detection unit 14 may acquire an instruction area having a fixed size or shape. In such a case, for example, first, the area detection unit 14 acquires a pressed point (x, y) on the touch panel. Next, the region detection unit 14 acquires information on a region having a predetermined size or shape (for example, a rectangle or a circle) with the point (x, y) as the center. Note that the size of the predetermined size instruction area may be customized by an individual, or may be customized by user attributes (gender, age, etc.).

  Next, the determination process in step S204 will be described using the flowchart of FIG.

  (Step S401) The determination unit 15 substitutes 0 for the counter c. The counter c is a variable for counting graphic information existing in the designated area.

  (Step S402) The determination unit 15 substitutes 1 for a counter i.

  (Step S403) The determination unit 15 determines whether or not the i-th graphic information exists in the graphic information storage unit 11. If the i-th graphic information exists, the process goes to step S404. If the i-th graphic information does not exist, the process goes to step S410.

  (Step S <b> 404) The determination unit 15 acquires the i-th graphic information from the graphic information storage unit 11.

  (Step S405) The determination unit 15 determines whether or not there is an overlap between the graphic area indicated by the graphic information acquired in step S404 and the designated area. If there is an overlap, the process goes to step S406, and if there is no overlap, the process goes to step S409. Note that the case where there is an overlap is a case where a figure (i-th figure) corresponding to the i-th figure information exists in the designated area.

  (Step S406) The determination unit 15 increments the counter c by 1.

  (Step S407) The determination unit 15 determines whether c is equal to or greater than a threshold value (for example, 2). If c is greater than or equal to the threshold value, go to step S408, and if c is not greater than or equal to the threshold value, go to step S409.

  (Step S408) The determination unit 15 substitutes information (for example, “1”) indicating that there are more than a predetermined number of figures in the variable “determination result”. Return to upper process.

  (Step S409) The determination unit 15 increments the counter i by one. The process returns to step S402.

  (Step S410) The determination unit 15 substitutes information (for example, “0”) indicating that there are no more than a predetermined number of figures in the variable “determination result”. Return to upper process.

  Next, the enlargement process in step S206 will be described using the flowchart of FIG.

  (Step S501) The enlargement unit 16 generates a new window.

  (Step S502) The enlargement unit 16 determines the display position of the window. The display position may be a position centered on the indication area, may be a position that does not overlap the indication area, may have the least figure, or a corner (any one of four corners) on the screen. Note that the position that does not overlap the designated area and the area with the least number of figures can be determined using the figure information in the figure information storage unit 11.

  (Step S503) The enlargement unit 16 acquires an area including the designated area from the designated screen or window. Note that the area including the instruction area may have a fixed size or may change dynamically according to the figure. For example, the enlargement unit 16 may acquire an area that includes all the graphics included in the designated area and does not include other graphics as much as possible.

  (Step S504) The enlargement unit 16 enlarges the area acquired in step S503 so as to have a new window size.

  (Step S505) The enlargement unit 16 displays the area enlarged in step S504 in the window generated in step S501. Return to upper process.

  In the flowchart of FIG. 5, the enlarged area is displayed in a new window. However, the enlargement unit 16 may simply enlarge the entire current screen or the entire display of the indicated window.

  In the flowchart of FIG. 5, the enlargement unit 16 may enlarge the area at a fixed magnification, may enlarge the area so that only one figure enters the designated area, The magnification may be changed according to the number or type of the figure. The type of figure is usually a type of shape such as a triangle, rectangle, or circle, but it may be a line type that forms the figure, a type of command that created the figure, or a type of data structure of the figure.

  Hereinafter, the operation of the graphics processing apparatus 1 in the present embodiment will be described using two specific examples.

(Specific example 1)
In the specific example 1, when the graphic processing apparatus 1 tries to designate a singular point in the drawing displayed on the display with a finger, when there are two or more singular points in the designated area designated by the finger, It is assumed that an operation of automatically enlarging an area including an instruction area and displaying the enlarged area in a different window different from the drawing is performed.

  Now, it is assumed that a large amount of graphic information (including singularity information) is stored in the graphic information storage unit 11. In this situation, it is assumed that the user inputs a drawing display instruction to the graphic processing apparatus 1. The receiving unit 12 receives a drawing display instruction. Next, the graphic display unit 13 reads the graphic information corresponding to the drawing display instruction from the graphic information storage unit 11 and displays one or more graphics (drawings) corresponding to the drawing information at the positions indicated by the position information. . A display example of such a drawing is shown in FIG.

  Next, as shown in FIG. 6, it is assumed that the user touches the display with a finger to indicate a specific singularity with the finger. Then, the accepting unit 12 accepts an instruction to select a figure (here, a singular point).

  Next, the area detection unit 14 acquires the instructed position information (x1, y1). And the area | region detection part 14 acquires the information of the square area | region of fixed size centering on positional information (x1, y1). The information of this area is (x2, y2) (x3, y3). Note that “x1 = (x2 + x3) / 2” and “y1 = (y2 + y3) / 2”. Also, | x2-x3 | and | y2-y3 | are fixed lengths. Furthermore, it is preferable that | x2-x3 | and | y2-y3 | can be customized for each user.

  Next, the determination unit 15 determines whether or not there are more than a predetermined number (here, “2”) of singular points that can be selected in the acquired indication area. Judgment is made using the position information of two or more singular points of. Here, it is assumed that the determination unit 15 determines that two or more selectable singular points exist in the acquired indication area.

  Next, the enlargement unit 16 generates a new window 81. Then, the enlargement unit 16 determines the display position of the window 81. Here, it is assumed that the enlargement unit 16 matches the instructed position information (x1, y1) with the center point of the window 81, for example.

  Next, the enlargement unit 16 acquires an area including the instruction area (see 71 in FIG. 7) from the screen (drawing) in FIG.

  Next, the enlargement unit 16 enlarges the acquired area 71 so as to have a new window size (see 72 in FIG. 7).

  Next, the enlargement unit 16 displays the enlarged area 71 in the generated window 81 (see FIG. 8). Next, the user designates a specific singular point in the window 81 with a finger.

  One singular point was selected by the above processing. After selecting one singular point, for example, the user performs drawing.

(Specific example 2)
In the second specific example, the graphic processing apparatus 1 automatically displays the entire screen including the instruction area when there are two or more figures in the instruction area indicated by the finger in a situation where a plurality of figures are displayed on the display. It is assumed that the operation of enlarging and displaying the area is performed.

  Now, it is assumed that the graphic information management table shown in FIG. 9 is stored in the graphic information storage unit 11. The figure information management table manages figures. The graphic information management table of FIG. 9 stores a large number of graphic information records having graphic related information and position information. In FIG. 9, here, the graphic related information is information indicating the type of graphic. The graphic-related information may include graphic attribute values (circle radius, non-default line type, non-default line color, non-default background color, etc.). The position information is usually a set of points that specify the position of the figure.

  In this situation, it is assumed that the user inputs a drawing display instruction to the graphic processing apparatus 1. The receiving unit 12 receives a drawing display instruction. Next, the graphic display unit 13 reads the graphic information of FIG. 9 and displays it on the touch panel display. An example of such graphic display is shown in FIG.
