DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of controlling the setting of numerical values in an electronic device, and more particularly to a method of setting a predetermined numerical value by a rough operation.

[0002]

2. Description of the Related Art In the operation of electronic equipment, many kinds of numerical values are often set. A rotary knob, a button, or the like is used for setting a numerical value, and the numerical value is continuously changed to set the numerical value on the device. In such an operation of continuously changing the numerical value and finally setting the numerical value, it is often desired to set a predetermined numerical value. For example, in setting the voltage, the voltage is set to 0 V during the operation of changing the numerical value from positive to negative.

FIG. 6 shows that the voltage is reduced by 0.1.
This is a conventional example in which it is desired to temporarily set a set value to 0V or a value not lower than 0V. This is often done when the value has a special meaning, such as often using 0V as a reference value. Conventionally, when turning the rotary knob to change the numerical value, it is necessary to carefully operate the rotation of the rotary knob when it approaches 0 V, and in a rough operation, it exceeds 0 V and reaches a negative value such as Is not easy to set.

[0004]

When an arbitrary numerical value is set in an electronic device by continuously changing the value with a rotary knob or the like,
When a predetermined numerical value having a specific meaning, such as a reference numerical value often used as a set numerical value, is set, conventionally, when the value approaches the predetermined numerical value, the rotary knob is carefully operated to change the numerical value.

An object of the present invention is to provide a numerical value setting control method which can set a predetermined numerical value by a rough operation without particularly careful operation. Another object of the present invention is to
An object of the present invention is to provide a numerical value setting control method that can be operated with the same feeling even when a numerical value is further changed after exceeding a predetermined numerical value.

[0006]

According to the present invention, there is provided a numerical value setting control method for changing a numerical value of an electronic apparatus in a predetermined direction by operating a setting means such as a dial. The numerical value is changed in a predetermined direction according to the operation of the means, and when the numerical value reaches the predetermined value by the operation of the setting means and the setting means continues the operation in the predetermined direction, the numerical value is changed for a predetermined time. Is maintained at a predetermined value (or a value immediately before reaching the predetermined value), and after a predetermined time, the value is changed again in a predetermined direction according to an operation of the setting means. As described above, since the change of the numerical value stops at the predetermined numerical value (or the numerical value immediately before reaching the predetermined numerical value) for a predetermined time, the numerical value can be easily set to the predetermined numerical value (or a numerical value close to the predetermined numerical value not exceeding the predetermined numerical value). In any of these steps, the user can always operate with the same operational feeling.

[0007]

2 and 3 show one embodiment of the method of the present invention. The numerical value is changed by a rotary knob or the like to decrease the set value of the voltage by 0.1, and each of the values becomes 0.
This is an example in which the change is temporarily stopped at a value that does not become lower than V and 0V. At this time, 0V is set as a predetermined numerical value. In any case, when the numerical value is decreased by 0.1 at a time, if it exceeds 0.071 V, then -0.0.
It should be 029V. Therefore, in FIG.
When the numerical value is 0.071 V, for a predetermined period of time, for example, 1 second, the numerical value change stops even if the rotary knob is rotated to change the numerical value. In FIG.
At 00V, the numerical value stops for a predetermined time even if the numerical value is to be changed. After the change of the numerical value is stopped, the numerical value does not change even if the rotary knob is rotated for a predetermined time, so that the numerical value can be easily set to the predetermined numerical value by stopping the rotation. It is not necessary to rotate the rotary knob particularly carefully for setting the predetermined numerical value. If the rotary knob is continuously rotated in the same direction even after the stop of the numerical value change and the numerical value is to be varied, the numerical value change restarts after a predetermined time and exceeds the predetermined numerical value 0V to reach a negative numerical value. If the rotary knob is rotated in the opposite direction after the numerical value stops, the numerical value changes immediately in the opposite direction. Here, the embodiment in which the numerical value is decreased is shown, but the case of increasing the numerical value is also possible.

FIG. 1 shows a flow chart of the method of the present invention. In the first step 11, the numerical value is continuously changed. To change the numerical value, a well-known technique such as rotating a rotary knob attached to the electronic device or pressing a predetermined button may be used. In the second step 12, it is determined whether the changed numerical value exceeds a predetermined numerical value. When it is determined that the value does not exceed the predetermined value, the process proceeds to the third step 13, the changed value is set as a new value in the electronic device, and the process returns to the first step 11. If it is determined in the second step 12 that the value has exceeded the predetermined value, the process proceeds to a fourth step 14 where the predetermined value (or the final value before changing the value) is set as a new value in the electronic device. In the fifth step 15, it is determined whether the rotary knob continues to rotate in the same direction, that is, whether the direction in which the numerical value is to be changed is the same even after the numerical value change is stopped. Return. If the numerical value change directions are the same, proceed to the sixth step 16 to measure a predetermined time. If the predetermined time has not elapsed, return to the fifth step 15 to determine the rotation direction of the rotary knob. The predetermined time is counted, and the process returns to the first step 11 when the predetermined time has elapsed.

FIG. 4 shows an embodiment of an electronic device 40 to which the method of the present invention is applied. The numerical value to be set is changed by the rotary knob 41. Of course, a button or the like may be used instead of the rotary knob. Using a key 42 on the front panel of the electronic device 40, a frequently used reference value or the like is set as a predetermined value. This predetermined numerical value is stored in the random access memory (RAM) 44. The read only memory (ROM) 43 stores a program for executing the method of the present invention. The microprocessor 45 stores this program in the ROM 4 as needed.
3 and executed. If necessary, a predetermined value may be stored in the ROM 43 in advance. Display control circuit 47
Controls the display on the display device 48. The display device 48
The numerical values set for the electronic device 40 are displayed.

FIG. 5 shows an embodiment for realizing the present invention without using a microprocessor. The rotary knob 50 is used for continuously changing a numerical value. Of course, any device that changes a numerical value such as a button may be used. The rotation of the rotary knob is digitized by the decoder 52, and the value of the up / down counter 54 is increased or decreased. A predetermined numerical value is input to the comparator 56 as a comparison numerical value, and the output of the up / down counter 54 is compared with the predetermined numerical value. If Up / Down Counter 5
When the output of 4 matches the predetermined value or exceeds the predetermined value, the comparator 56 stops the increment or decrement of the up / down counter 54 for a predetermined time, and returns the predetermined value or the final value before changing the value. Output to the display device. On the other hand, when the output of the up / down counter 54 does not match the predetermined value or does not exceed the predetermined value, the comparator 56 outputs the output of the up / down counter 54 to the display device 58 as it is. The change of the numerical value by the rotation operation of the rotary knob when the numerical value change stops is the same as described above. The display device 58 displays the output of the comparator 56 as a numerical value.

[0011]

According to the method of the present invention, when a set value such as a rotary knob is continuously varied in a predetermined direction in setting a numerical value of an electronic device, the predetermined value or the predetermined value is reached. The change of the numerical value with the immediately preceding numerical value is temporarily stopped for a predetermined time. Therefore, if a numerical value having a special meaning, such as a frequently used reference numerical value, is set as the predetermined numerical value, the predetermined numerical value can be set in the electronic device even with a rough operation. Further, when it is desired to set a numerical value exceeding the predetermined numerical value, it is only necessary to continue the same operation as before the predetermined numerical value is reached during and after the predetermined time, and the numerical value can always be changed with the same operational feeling.
