JP-A-5-12428

  By the way, in a display device that displays display information such as a figure using a plurality of pixels arranged two-dimensionally, a figure displayed by moving a point drawn by the pixel to a pixel of another coordinate If an attempt is made to move the entire image, the coordinate conversion processing time will be as much as the number of pixels used to display the graphic. In order to avoid this, if graphic information adapted to the assumed movement is stored in advance, a large amount of memory is consumed. For example, in the case of rotational movement, if graphic information matched to the entire rotation angle in 1 ° increments is stored in advance, it is necessary to store in advance 360 figures from 0 ° to 359 °, It consumes memory. As the pixels become finer or the area of the figure increases, the processing time increases and the memory consumption also increases.

<First Embodiment>
[Configuration of electronic timepiece 1]
FIG. 1 is a block diagram showing a functional configuration of an electronic timepiece 1 according to the first embodiment.
The electronic timepiece 1 is a device that measures and displays the current time, direction, and the like. The electronic timepiece 1 is, for example, a watch worn on the user's body such as a wristwatch or a pocket watch, but is not limited thereto.

  The electronic timepiece 1 includes a microcomputer 2 (computer), an operation receiving unit 3, a display device 4, a vibrator 5, a direction sensor 6, a GPS (Global Positioning System) 7, a power supply unit 8, and the like.

  The microcomputer 2 controls the overall operation of the electronic timepiece 1. The microcomputer 2 includes a CPU 21 (Central Processing Unit), a ROM 22 (Read Only Memory), a RAM 23 (Random Access Memory), an oscillation circuit 24, a frequency dividing circuit 25, a time counting circuit 26, and a timer circuit 27. .

  The CPU 21 is a processor that performs various kinds of arithmetic processing, and performs control operations of each part of the electronic timepiece 1 according to a program stored in the ROM 22. The CPU 11 functions as a control unit.

  The ROM 22 stores a program for the CPU 21 to execute a control operation, data necessary for executing the program, and the like. The ROM 22 may include a non-volatile memory such as a flash memory capable of rewriting and updating data in addition to or instead of the mask ROM.

For example, the ROM 22 stores an azimuth calculation program 221 and a figure rotation program 222 (details will be described later).
The ROM 22 stores graphic information of the triangle T. In the present embodiment, the triangle T is a figure displayed on the display device 4 to indicate the direction, and as shown in FIG. 2, the triangle T is filled with black. The ROM 22 stores graphic information of the triangle T in a state indicating the 0 ° direction (12 o'clock direction) of the electronic timepiece 1. This graphic information is information for displaying the triangle T on the display device 4, and is information that can specify at least the positions of the pixels corresponding to the three vertices of the triangle T when the triangle T is displayed on the display device 4. . For example, the graphic information of the triangle T may be image data indicating whether or not each pixel of the display device 4 is drawn (black dots are made), and at least three vertices of the triangle T in the display device 4 It may be information indicating the position of the corresponding pixel. For example, it may be information indicating the positions of pixels corresponding to the three vertices of the triangle T and one point inside. In the present embodiment, description will be made assuming that the graphic information is image data.
Further, the ROM 22 stores map data.

  The RAM 23 provides a working memory space to the CPU 21 and stores temporary data.

  The oscillation circuit 24 is connected to the vibrator 5, generates a signal having a predetermined frequency, and outputs the signal to the frequency dividing circuit 25.

  The frequency dividing circuit 25 outputs a frequency-divided signal obtained by frequency-dividing the frequency signal input from the oscillation circuit 24 by a set frequency dividing ratio. The setting of the frequency division ratio can be changed by the CPU 21.

The timer circuit 26 holds the current date and time by counting the frequency-divided signal having a predetermined frequency input from the frequency dividing circuit 25.

  The display device 4 is configured by, for example, a MIP (memory in pixel) liquid crystal in which a plurality of pixels are arranged two-dimensionally, and displays various information based on the control of the CPU 21. In the present embodiment, the case where the display device 4 is a monochrome liquid crystal will be described as an example, but the present invention is not limited to this.

  The vibrator 5 is composed of a quartz vibrator or the like, and uses a piezoelectric phenomenon of quartz to generate a certain frequency from its mechanical resonance.

The direction sensor 6 includes, for example, a biaxial or triaxial geomagnetic sensor, measures the direction in which the electronic timepiece 1 is facing, and outputs the measured direction to the CPU 21.
The GPS 7 receives the GPS signal, acquires the current position, and outputs it to the CPU 21.
The power supply unit 8 supplies power required for the operation of each unit of the electronic timepiece 1 to each unit. The power supply unit 8 supplies power output from a battery (not shown) at the operating voltage of each unit. As the battery, a solar panel that generates power according to incident light, a secondary battery that stores the generated power, or the like may be provided, or a dry battery, a rechargeable battery, or the like may be detachably provided.

[Operation of electronic watch 1]
Next, the operation of the electronic timepiece 1 in the first embodiment will be described.
In the electronic timepiece 1, when the destination is set by the operation reception unit 3, the CPU 21 displays a triangle T indicating the direction of the destination on the display device 4.

  For example, when the destination is set by the operation accepting unit 3, the CPU 21 first cooperates with the azimuth calculation program 221 to determine the destination based on the current position input from the GPS 7 and the map data stored in the ROM 22. The direction of the destination relative to the current position of the electronic timepiece 1 is calculated based on the position information of the electronic timepiece 1, and the ROM 22 is calculated based on the calculated direction of the destination and the direction that the electronic timepiece 1 is input from the direction sensor 6. An angle θ for rotating the triangle T stored in is calculated.

  Next, the CPU 21 executes the rotation process A in cooperation with the graphic rotation program 222 and rotates the triangle T displayed at the first position by the angle θ based on the graphic information stored in the ROM 22. The image is displayed on the display device 4 while being rotationally moved to the second position.

FIG. 3 is a flowchart showing the rotation process A executed by the cooperation of the CPU 21 and the graphic rotation program 222. Hereinafter, the rotation process A will be described with reference to FIG.
In the following description, the horizontal direction of the display device 4 (image data) is the x direction, and the vertical direction is the y direction. Further, the upper left corner is the origin, the x coordinate value increases toward the right, and the y coordinate value increases toward the bottom.

  First, as shown in FIG. 4, the CPU 21 sets the apex of the triangle T as P1, P2, P3, one internal point as P4, and P1, P2, P3, and P4 as angles of rotation around the center of the display device 4. Rotate (step S11). That is, the positions when P1 to P4 are rotated by θ ° about the center of the display device 4 are obtained by coordinate conversion.

  Next, the CPU 21 calculates mathematical formulas (for example, x = ay + b) of the straight line L1 connecting P1 and P2, the straight line L2 connecting P2 and P3, and the straight line L3 connecting P3 and P1 (step S12).

  Next, the CPU 21 acquires the positional relationship (left-right positional relationship) between P4 and each of L1, L2, and L3 (step S13).

Next, as shown in FIG. 5, the CPU 21 obtains the minimum rectangular area A including the three vertices P1, P2, and P3, and sets the rectangular area A as a check target range (step S14).
Here, it is determined whether or not the pixel is included in the triangle T, and the range of pixels for which drawing control is performed is not the entire display device 4 (image data) but includes three vertices of the triangle T. By limiting to the smallest area, the processing time can be reduced.

  Next, the CPU 21 selects one pixel from the rectangular area A (step S15). For example, the upper left pixel of the rectangular area A is selected.

Next, the CPU 21 determines whether or not the positional relationship between the selected pixel and L1 is the same as the positional relationship between P4 and L1 (step S16).
For example, when the positional relationship between P4 and L1 is the relationship shown in FIG. 4, that is, when P4 is to the right of L1, (the x coordinate of P4 is the x coordinate when the y coordinate of P4 is applied to the expression of L1 CPU 21 determines whether or not the x coordinate of the selected pixel is larger than the value of the x coordinate obtained when the y coordinate of the pixel is applied to the expression of L1. When it is determined that the x coordinate of the selected pixel is larger than the value of the x coordinate obtained when the y coordinate of the pixel is applied to the expression of L1, the positional relationship between the selected pixel and L1 is P4 and L1. It is determined that the positional relationship is the same.

  When it is determined that the positional relationship between the selected pixel and L1 is different from the positional relationship between P4 and L1 (step S16; NO), the CPU 21 determines that the selected pixel is outside the triangle T (step S19). The process proceeds to step S21.

When it is determined that the positional relationship between the selected pixel and L1 is the same as the positional relationship between P4 and L1 (step 16; YES), the CPU 21 determines that the positional relationship between the selected pixel and L2 is P4 and L2. It is determined whether or not the positional relationship is the same (step S17).
For example, when the positional relationship between P4 and L2 is the relationship shown in FIG. 4, that is, when P4 is to the right of L2, (the x coordinate of P4 is the x coordinate when the y coordinate of P4 is applied to the expression of L2 It is determined whether or not the x coordinate of the selected pixel is larger than the value of the x coordinate obtained when the y coordinate of the pixel is applied to the expression of L2. When it is determined that the x coordinate of the selected pixel is larger than the x coordinate value obtained when the y coordinate of the pixel is applied to the expression of L2, the positional relationship between the selected pixel and L2 is P4 and L2. It is determined that the positional relationship is the same.

  When it is determined that the positional relationship between the selected pixel and L2 is different from the positional relationship between P4 and L2 (step S17; NO), the CPU 21 determines that the selected pixel is outside the triangle T (step S19). The process proceeds to step S21.

When it is determined that the positional relationship between the selected pixel and L2 is the same as the positional relationship between P4 and L2 (step 17; YES), the CPU 21 determines that the positional relationship between the selected pixel and L3 is P4 and L3. It is determined whether or not the positional relationship is the same (step S18).
For example, when the positional relationship between P4 and L3 is the relationship shown in FIG. 4, that is, when P4 is to the left of L3 (the x coordinate of P4 is the x coordinate when the y coordinate of P4 is applied to the expression of L3 If the x coordinate of the selected pixel is smaller than the value of the x coordinate obtained when the y coordinate of the pixel is applied to the expression of L3, it is determined. When it is determined that the x coordinate of the selected pixel is smaller than the x coordinate value obtained when the y coordinate of the pixel is applied to the expression of L3, the positional relationship between the selected pixel and L3 is P4 and L3. It is determined that the positional relationship is the same.

  When it is determined that the positional relationship between the selected pixel and L3 is different from the positional relationship between P4 and L3 (step S18; NO), the CPU 21 determines that the selected pixel is outside the triangle T (step S19). The process proceeds to step S21.

  When it is determined that the positional relationship between the selected pixel and L3 is the same as the positional relationship between P4 and L3 (step 18; YES), the CPU 21 determines that the selected pixel exists inside the triangle T. Then, the position of the pixel is acquired (step S20), and the process proceeds to step S21.

In step S21, the CPU 21 determines whether or not all the pixels in the rectangular area A have been checked (step S21). If it is determined that all the pixels have not been checked (step S21; NO), the CPU 21 returns to step S15.
If it is determined that all the pixels have been checked (step S21; YES), the CPU 21 renders the pixel determined to be a pixel inside the triangle T in black, and displays the other pixels on the display device 4 without filling them. (Step S22), and the rotation process A ends.

  When any of L1, L2, and L3 is horizontal, the positional relationship between the straight line and the selected pixel deviates from the condition for determining whether or not it is inside the triangle T.

  FIG. 6 shows the result of rotating the triangle T shown in FIG. In the rotation process A, the vertexes P1, P2, and P3 of the triangle T and the point P4 inside the triangle T are rotated around the center of the display device 4, and the rotated vertices P1, P2, and P3 For the pixel in the smallest rectangular area A to be included, whether the positional relationship between the pixel and L1, L2, L3 is the same as the positional relationship between P4 and L1, L2, L3 (the pixel is in L1, L2, L3) Whether it is inside the triangle T or not is determined by whether or not it is on the same side as P4. If it is determined that the pixel is inside the triangle T, the pixel is drawn in black. A pixel for which it is determined that the positional relationship with one straight line is different from P4 is determined to be outside the triangle T at that time, and is removed from the drawing target. Therefore, the rotation process is performed on all the pixels inside the triangle T, and the state in which the triangle T is rotated can be obtained by simple calculation compared to the case where the process of obtaining the coordinates after rotation of each pixel and drawing it in black is performed. Therefore, processing time can be reduced. In addition, since only the basic graphic information of the triangle T of 0 ° needs to be stored in the ROM 22, consumption of the ROM 22 can be suppressed.

<Second Embodiment>
Next, a second embodiment of the present invention will be described.
Since the configuration of the electronic timepiece 1 in the second embodiment is the same as that described in the first embodiment, the description will be referred to and the operation of the second embodiment will be described below.

  In the electronic timepiece 1, when the destination is set by the operation receiving unit 3, the CPU 21 first converts the current position input from the GPS 7 and the terrain data stored in the ROM 22 in cooperation with the azimuth calculation program 221. The direction of the destination with respect to the current position of the electronic timepiece 1 is calculated based on the position information of the destination based on the information, and based on the calculated direction of the destination and the direction to which the electronic timepiece 1 input from the direction sensor 6 is directed. Thus, the angle θ for rotating the triangle T stored in the ROM 22 is calculated.

  Next, the CPU 21 executes the rotation process B in cooperation with the graphic rotation program 222 and rotates the triangle T displayed at the first position by the angle θ based on the graphic information stored in the ROM 22. The image is displayed on the display device 4 while being rotationally moved to the second position.

  FIG. 7 is a flowchart showing the rotation process B executed by the cooperation of the CPU 21 and the graphic rotation program 222. Hereinafter, the rotation process B will be described with reference to FIG.

  First, the CPU 21 rotates the vertices P1, P2, and P3 of the triangle T by an angle θ with the center of the display device 4 as the rotation center (step S31). That is, the positions when P1 to P4 are rotated by θ ° about the center of the display device 4 are obtained by coordinate conversion.

  Next, as shown in FIG. 8, the CPU 21 sets P1, P2, and P3 to Q1, Q2, and Q3 in order from the smallest y coordinate (step S32), and connects the straight lines connecting Q1 and Q2 to L1, Q2, and Q3. A straight line is L2, and a straight line connecting Q3 and Q1 is L3 (step S33). If there are vertices with the same y coordinate, Q1, Q2, and Q3 are assigned from the smallest x coordinate.

  Next, the CPU 21 calculates an equation (for example, x = ay + b) for each of L1, L2, and L3 (step S34).

Next, the CPU 21 obtains the smallest rectangular area A0 including the three vertices Q1, Q2, and Q3, and divides the rectangular area A0 into two by the horizontal line passing through Q2, thereby obtaining the rectangular areas A1 and A2. Is set as a pixel check target range (step S35).
Here, it is determined whether or not the pixel is included in the triangle T, and the range of pixels for which drawing control is performed is not the entire display device 4 (image data) but includes three vertices of the triangle T. By limiting to the smallest area, the processing time can be reduced.

  Next, in the processing of steps S36 to S40, the CPU 21 selects pixels for one row one by one in order from the smallest x coordinate in order from the smallest y coordinate in the rectangular area A1 shown in FIG. 9A. Then, it is determined whether or not the selected pixel is inside the triangle T1. When the selection of the pixels for one row is completed, the process moves to the next row, selects the pixels for one row one by one, and repeats the process of determining whether or not the selected pixel is inside the triangle T.

  First, in step S36, the CPU 21 selects one pixel in the rectangular area A1 (step S36). The selection order of the pixels is as described above.

  Next, the CPU 21 determines whether or not the selected pixel exists between L1 and L3 (step S37).

  Here, whether or not the selected pixel is located between L1 and L3 depends on whether the x coordinate of the selected pixel is the same as the y coordinate of the point on L1 and the x coordinate of the point on L3. It can be judged by whether or not it is located between. At this time, the x coordinate of the point on L1 of the same y coordinate as that of the pixel and the x coordinate of the point on L3 are linear equations x = ay + b (a and b are different in L1 and L3, respectively). In general, by substituting the value of the y-coordinate of the selected pixel into y of x), the x-coordinate on L1 and the x-coordinate on L3 of the row are obtained. However, multiplication is more complex and processing time than addition. Therefore, in this embodiment, when the processing for the pixels for one row is completed and the process proceeds to the lower row, the slope a is added to the current x coordinate of L1, and the slope a is added to the current x coordinate of L3. By adding, the x coordinates of L1 and L3 in the next row are calculated. As a result, the processing speed can be increased as compared with the case of using x = ay + b.

  When determining that the selected pixel does not exist between L1 and L3 (step S37; NO), the CPU 21 determines that the selected pixel is outside the triangle T (step S38), and proceeds to step S40.

  When it is determined that the selected pixel exists between L1 and L3 (step S37; YES), the CPU 21 determines that the selected pixel exists inside the triangle, and sets the selected pixel as a pixel to be drawn in black. The position is acquired (step S39), and the process proceeds to step S40.

  In step S40, the CPU 21 determines whether or not the processing for all the pixels in the rectangular area A1 has been completed (step S40). When it is determined that the processing for all the pixels in the rectangular area A1 has not been completed (step S40; NO), the CPU 21 returns to step S36 and executes the processing of steps S36 to S40 for the next pixel.

  When it is determined that the processing for all the pixels in the rectangular area A1 has been completed (step S40; YES), the CPU 21 proceeds to step S41.

  In the processing of steps S41 to S45, the CPU 21 selects pixels for one row one by one in order from the smallest x coordinate in order from the smallest y coordinate in the rectangular area A2 shown in FIG. 9B. Then, it is determined whether or not the selected pixel is inside the triangle T1. When the selection of the pixels for one row is completed, the process moves to the next row, selects one pixel for each row, and repeats the process of determining whether the selected pixel is inside the triangle T1.

  First, in step S41, the CPU 21 selects one pixel in the rectangular area A2 (step S41). The selection order of the pixels is as described above.

  Next, the CPU 21 determines whether or not the selected pixel exists between L2 and L3 (step S42). Since the process of step S42 is the same as that in which L1 in step S37 is replaced with L2, the description in step S37 is cited.

  When determining that the selected pixel does not exist between L2 and L3 (step S42; NO), the CPU 21 determines that the selected pixel is outside the triangle T (step S43), and proceeds to step S45.

  When it is determined that the selected pixel exists between L2 and L3 (step S42; YES), the CPU 21 determines that the selected pixel exists inside the triangle, and sets the selected pixel as a pixel to be drawn in black. The position is acquired (step S44), and the process proceeds to step S45.

  In step S45, the CPU 21 determines whether or not the check for all the pixels in the rectangular area A2 has been completed (step S45). When it is determined that the check for all the pixels in the rectangular area A2 has not been completed (step S45; NO), the CPU 21 returns to step S41 and executes the processes of steps S41 to S45 for the next pixel.

  If it is determined that all the pixels in the rectangular area A2 have been checked (step S45; YES), the CPU 21 draws the pixels determined to be black and displays the other pixels as unfilled. Display is performed on the device 4 (step S46), and the rotation process B is terminated.

  When either L1 or L2 is horizontal, the positional relationship between the straight line and the selected pixel deviates from the condition for determining whether or not it is inside the triangle T.

  In the rotation process B, the vertexes Q1, Q2, and Q3 of the triangle T are rotated around the center of the display device 4 as the rotation center, and the smallest rectangular area A including the rotated vertices Q1, Q2, and Q3 is included. For each pixel in the rectangular area A1 above the horizontal line passing through Q2, whether or not the pixel exists between L1 and L3 determines whether it is inside the triangle T and below the horizontal line passing through Q2 For each pixel in the rectangular area A2, it is determined whether the pixel is inside the triangle T depending on whether the pixel exists between L2 and L3. Therefore, since there are two straight lines for comparing positions with each pixel in order to determine whether or not the pixel is inside the triangle, the determination conditions are further reduced as compared with the first embodiment, so that the processing is further accelerated. And processing time can be reduced. Also, when the row to be checked in the rectangular area A1 is moved, the x coordinates of L1 and L3 are obtained by adding the slope a of each straight line to the x coordinate of the previous row, thereby using complex multiplication. This is unnecessary, and the processing can be further speeded up.

As described above, according to the electronic timepiece 1, when the triangle T stored in the ROM 22 is displayed on the display device 4 while being moved, the CPU 21 rotates the vertex of the triangle T and moves the triangle T after the movement. A straight line connecting the vertices of the display device 4 is obtained, and drawing control of each pixel is performed based on the positional relationship between each pixel of the display device 4 and the obtained straight line, so that the triangle T is rotated and displayed on the display device 4. Let
Therefore, the pixels to be rotated are only the pixels at the vertices, and the other pixels are rotated by determining whether they are inside the triangle T based on the positional relationship with the straight line connecting the vertices and performing drawing control. Since the triangle T in the state is displayed, it is possible to display the state in which the triangle T is rotated by a simple operation compared to the case where all the pixels of the triangle T are rotated to obtain the coordinates after rotation. Time can be reduced. Further, since it is not necessary to store the image data of the triangle T for all the rotation angles from 0 ° to 360 ° in the ROM 22, it is possible to reduce the processing time while suppressing the consumption of the ROM 22.

  In addition, the description content in the said embodiment is a suitable example of the electronic timepiece which concerns on this invention, and is not limited to this.

  For example, in the above embodiment, the case where the display device according to the present invention is provided in the electronic timepiece 1 has been described as an example, but the present invention is not limited to this. For example, the display device according to the present invention may be a single display device dedicated to display, or may be provided in another electronic device.

  Moreover, in the said embodiment, although the case where the display device 4 was a display device using a monochrome liquid crystal was demonstrated as an example, the display device using a color liquid crystal may be used. In this case, the inside of the triangle T is not limited to being drawn in black, but may be another color. Further, the outside of the triangle T may be drawn with a color different from the inside.

  In the above embodiment, the pixels inside the triangle T are determined and the pixels inside the triangle T are drawn in a color such as black. However, the pixels inside the figure such as the triangle T are determined and The boundary between the pixel and the external pixel may be drawn with a color such as black.

  In the above-described embodiment, the case where the graphic to be displayed is a triangle has been described as an example. However, the algorithm for the rotation process described above is a graphic surrounded by straight lines connecting other vertices (graphic having no dent). It is applicable to. Also, even other figures can be rotated using the above-described algorithm of rotation processing by dividing them into triangles.

  In the above embodiment, the case of rotating a figure has been described as an example. However, the algorithms of the rotation processes A and B can also be applied to movement without rotation. That is, if the vertex is moved in step S11 and step S31 and the subsequent processing is performed based on the moved vertex, the figure can be displayed in a moved state.

  In the above embodiment, the graphic information of the triangle T is stored in advance using the ROM 22 as the storage unit, but the storage unit may be a temporary storage unit such as the RAM 23. For example, when one figure is divided into a plurality of triangles and the present invention is applied to each triangle, the figure information such as the vertex information of each divided triangle stored in the RAM 23 is used. The present invention can be implemented.

  In addition, the detailed configuration and detailed operation of the electronic timepiece can be appropriately changed without departing from the spirit of the invention.
