Abstract

PROBLEM TO BE SOLVED: To realize a scrolling operation on which the will of an operator is reflected by installing a continuos scrolling means which continuously moves a picture even if the operation of an operation shaft is released and starting the continuous scrolling means when the operation quantity of a direction indication means exceeds prescribed quantity based on a detected result. SOLUTION: A micro computer connected to a joystick 10 detects the installation state of a fixed terminal Smn. Thus, the operation state of an operation shaft 1 is grasped. When an operator operates the joystick 10, a picture is moved to an operation direction (direction where operation shaft 1 is inclined). When the inclined angle of the operation shaft 1 is small (fixed terminal S1n is grounded), the picture is continuously moved until the operation of the operation shaft 1 is released. When the inclined angle of the operation shaft 1 is large (fixed terminal S2n is grounded), the picture is continuously moved even if the operation of the operation shaft 1 is released. The picture is continuously moved until the movement operation of the picture to the other direction and the other operation except for the operation of the joystick 10 are executed, for example.

In step S3, it is determined whether or not a continuous scroll operation has been instructed. If the continuous scroll has been instructed, the process proceeds to step S4, and if there is no continuous scroll instruction, the process proceeds to step S6. This determination differs depending on the type of the operation unit 41, but in the case of FIG. 1, it is determined by the grounded fixed contact, in the case of FIG.

In step S4, the flag A is set to the state of continuous scrolling (1), and the flow proceeds to step S5. In step S5, the parameters X and Y are each doubled in order to make the scroll speed twice the normal speed, and the process proceeds to step S6. In step S6, the map displayed on the screen is moved X in the x direction (right direction), and Y is moved in the y direction (up direction).
Moving. It should be noted that the movement unit may be, for example, 1 pixel or 2 pixels, and the image may be moved by an amount obtained by multiplying the movement unit by X and Y. In step S7, it is determined by the flag A whether or not a continuous scroll instruction has been issued. If continuous scroll has been instructed, the process proceeds to step S8. If no continuous scroll instruction has been issued, the process ends. In step S8, it is determined whether or not there is another operation (an instruction operation in another direction or an operation unrelated to the direction instruction). If there is another operation, the process proceeds to step S9, and if not, the process proceeds to step S6. In step S9, the continuous scroll is canceled (the flag A is set to 0), and the process ends.

Next, a fourth embodiment of the present invention will be described. FIG. 7 is a diagram showing the principle configuration of the fourth embodiment of the present invention. In this embodiment, a joystick that outputs a voltage corresponding to the operation amount of the operation axis (for each of the horizontal direction (x direction) and the vertical direction (y direction)) is used as the operation unit 41. In this type of joystick, an operation shaft 73 is fixed by an x-axis swing arm that can rotate about an axis in the x direction and a y-axis swing arm that can rotate about an axis in the y direction. And a variable resistor VR1, VR2 connected to each axis of the arm and the y-axis swing arm, and a voltage corresponding to each operation amount of the operation shaft 73 in the x direction and the y direction (power is supplied by the variable resistors VR1, VR2 of the power supply voltage). The voltage Vcc is divided and output).

The output voltages V1 and V2 from the variable resistors VR1 and VR2 are such that V2 is the maximum value (V2max = Vcc) at the upper end operation position of the operation shaft 73 and V2 is the minimum value (V2min = 0) at the lower end operation position. ), V1 at the rightmost operation position
Is the maximum value (V1max = Vcc), V1 at the leftmost operation position
Is the minimum value (V1min = 0), and at the neutral position, the output voltages V1 and V2 are intermediate values (V1cen = 1 / 2V1ma).
x, V2cen = 1 / 2V2max). That is,
The output voltages V1 and V2 have values as shown in FIG. 8 at the end portions in eight directions and the neutral position (non-operating state), and are intermediate between the end portions and the neutral position according to the operation amount from the intermediate position. Value.

Next, the relationship between the output voltages V1 and V2 and the image moving speed (image moving amount in one process) will be described. Since the moving speed is 0 at the neutral position, first, the output voltages V1 and V2 and the voltage 1 / 2V1ma at the neutral position
x, 1/2 V2max. Next, in order to obtain the actual operation ratio with respect to the maximum operation amount, the obtained difference is divided by the voltages V1max and V2max at the maximum operation position. This value is the ratio of the image moving speed to the operation amount of the operation shaft 73. Further, in order to set the maximum moving speed at the time of the maximum operation to a desired speed, the calculated ratio is multiplied by a value twice as large as the desired maximum moving speed (a value with respect to the unit speed) to obtain the image moving speed. That is, it may be calculated by the following equations 1 and 2. a = (V1-1 / 2V1max) / V1max × 2 · maximum moving speed formula 1 b = (V1-1 / 2V2max) / V2max × 2 · maximum moving speed formula 2 Next, the scroll operation is started. And will be described briefly. When the operator operates the operation shaft 73 of the joystick, the operation is performed in accordance with the operation direction (direction in which the operation shaft 73 is tilted) and the operation amount (inclination angle) of the operation shaft 73 while the operation is performed. Move the image at speed. If the tilt angle of the operation shaft 73 is large (exceeding 2/3 of the maximum operation amount), the operation shaft 7
Even if the operation of Step 3 is released, the image is moved, and the movement is continued at the speed at that time. For example, the movement of the image is continued until an operation for moving the image in another direction or an operation other than the operation of the joystick operation shaft 73 is performed. In the following processing, if the operation axis 73 is operated again to 2/3 or less of the maximum operation amount, the continuous scroll is released, but the continuous scroll is not released during the continuous scroll (A = 1). Can be prohibited from being released by the operation shaft 73 during the continuous scrolling by reducing the maximum operation amount.

Next, the processing performed by the microcomputer 43 in the fourth embodiment of the present invention will be described with reference to a flowchart. FIG. 9 is a flowchart showing the processing performed by the microcomputer 43. This processing is repeatedly performed during the operation of the electronic map display system. In step S81, it is determined whether or not an operation of scrolling the map is performed, and if there is an operation, the process proceeds to step S82, and if there is no operation, the process proceeds to step S85. In step S82, the output voltages V1 and V2 from the joystick are detected, and the image moving speeds a and b are calculated according to the above-described equations 1 and 2, and the process proceeds to step S83.
Here, the maximum moving speed is set to 3. Step S
At 83, it is determined whether the image moving speed a or b is larger than 2, and if either of the image moving speeds a and b is higher, the process proceeds to step S84, and if both are lower, the process proceeds to step S87. In step S84, the flag A is set to 1 for continuous scrolling, and the routine goes to step S85. In step S87, the flag A is set for normal scrolling.
Is set to 0, and the routine goes to Step S85. In step S85, the moving amount of the image for one image display process is set to a and b (X = a, Y = b) in the horizontal direction and the vertical direction, and the process proceeds to step S86. In step S86, the image is moved X in the horizontal direction and Y in the vertical direction, and the process ends. In step S87, it is determined based on the flag A whether or not the scroll is the continuous scroll. If the scroll is the continuous scroll (A = 1), the process proceeds to step S88. If the scroll is not the continuous scroll, the process ends. In step S88, it is determined whether or not there is a scroll operation in another direction or an operation other than scroll. If there is, the process proceeds to step S89.
Go to 86. In step S89, the continuous scroll is canceled (A = 0), and the process ends.
