Abstract

PURPOSE:To make a set displacement quantity variable in relation to the same variation quantity according to an operation object and improve operability by selecting an object to which numeric value setting is performed and converting, into required setting, the displacement quantity input while judging which setting object is set. CONSTITUTION:In an input device such as a jog shuttle key or a rotary knob, a movement distance is detected by detecting a value proportional to an rotation angle. This movement distance is converted into a set value by means of a conversion formula. On the other side, a mode selection unit 3 such as a panel key sets such an operation object like whether an object to be set is the time per scale on a display or not, or whether it is one to set the trigger position. The information of the operation object set in a selection unit 3 is input to a conversion formula selection unit 2. The conversion formula selection unit 2 selects a conversion formula used when the movement distance from the input device 1 is converted into its displacement quantity based on the information about real content of the operation object.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waveform observing device, and more particularly to a waveform observing device in which the operability is improved by making the setting of the displacement amount relative to the movement amount of each input device variable.

[0002]

2. Description of the Related Art Conventionally, in a waveform observing device, when a displayed waveform is scrolled, a displacement amount of a cursor movement is designated, or a numerical value such as a trigger position and a delay amount is set. In this case, a method of continuously specifying the amount of change using a jog shuttle key or a rotary knob is used.

Here, the jog shuttle key and the rotary knob indicate the amount of movement by rotation, and are proportional to the rotation angle, and based on the set amount of displacement, scrolling of the display screen of the screen or movement of the cursor is performed. It is done.

Whether the jog shuttle key or the rotary knob is used, the movement amount is detected by a rotary encoder or the like every time the knob changes by a certain rotation angle. This movement amount is input to a microprocessor (so-called CPU) that controls the entire waveform observation apparatus, and the detected movement amount is given as a displacement amount by calculation based on a definition formula.

The displacement amount obtained by converting the displacement amount is used to scroll the display screen or move the cursor on the display screen.

The conventional defining equation of the displacement amount relative to the movement amount is, for example, the movement amount +1 (+ in the rotary encoder +
If the displacement amount is set as +5 (for the case where 1 is detected), whether the setting target is the scroll position setting of the display screen or the trigger position position, +5 is set if the movement amount +1 is input. It will be given as a quantity.

This amount of displacement corresponds to a CRT dot on the display screen or a numerical value to be set, and if +5 is set, it corresponds to 5 CRT dots or 5 which is the smallest digit of the settable numerical value. Will be changed.

[0008]

Therefore, in the case where the settable range is large, such as in scroll display, the dynamic range of the set time such as the time (so-called T / div) per scale on the display screen is set. However, if the resolution of the displacement amount is too small or too large, it causes an imbalance in operation, resulting in a problem that the efficiency of observing the waveform is deteriorated and the intuition for recognizing the displayed waveform is also countered. The present invention solves such a problem, and provides a waveform observing device in which the operability is improved by changing the set displacement amount for the same variation amount of the jog shuttle key or the rotary knob according to the operation target.

[0009]

SUMMARY OF THE INVENTION The present invention comprises an input device for continuously changing a numerical setting from the outside, a mode setting section for selecting an object for which a numerical setting is performed,
Displacement amount conversion means for inputting information from the mode setting unit and the input device, determining which setting target setting has been made, and converting the displacement amount input from the input device into a predetermined setting, are provided. It is a waveform observation device characterized in that

[0010]

Since the waveform observing device of the present invention uses the conversion formula from the amount of movement from the input device to the amount of displacement to be set depending on the setting object, measurement is performed even if the same operation is performed with the jog shuttle key or rotary knob. Since the set value differs depending on the target, operability is improved.

1 is a block diagram showing the configuration of an embodiment of the present invention. In FIG. 1, reference numeral 1 is an input device such as a jog shuttle key or a rotary knob for externally inputting a numerical value or the like for changing the position on the display. Reference numeral 2 is a conversion formula selection unit that performs different conversion of the movement amount input from the input device 1 for each setting target, and 3 is a mode selection unit such as a panel key that selects the setting target.

As described in the conventional example, the displacement of the jog shuttle key or the rotary key for rotating the knob to input the set value is determined as an amount proportional to the rotation angle by the rotary encoder provided therein. To be detected. Also, in the shuttle ring in which the set value is input in the direction indicated by the knob, the displacement is detected by the rotary encoder using the direction indicated by the shuttle ring as the rotation angle, and the result is expressed by a value encoded in several bits. To be done.

For example, a jog ring having seven rotation angles in the right rotation direction and the left rotation direction as shown in FIG. 2 will be described. In FIG. 2, the inner circle represents the jog ring knob and the outer number represents the encoded value at that position.

As described above, in the input device 1 such as the jog shuttle key or the rotary knob, the amount of movement is detected by detecting a value proportional to the rotation angle. This moving amount is converted into a set value by a conversion formula.

On the other hand, in the mode selection section 3 such as the panel key, the object to be set by the jog shuttle key or the rotary knob is the time per scale (T / di) on the display.
v) or whether to set the trigger position, etc.

The information of the operation target set by the mode selection unit 3 is input to the conversion formula selection unit 2. The conversion formula selection unit 2 selects a conversion formula for converting a movement amount from the input device 1 into a displacement amount based on information about what the operation target is.

That is, in the conversion type selection unit 2, when the operation target is the movement of the display of the scroll screen, if the movement amount of +5 is input from the input device 1 such as the jog shuttle key or the rotary knob, the displacement amount becomes +15. Is set and output, and when the operation target is the movement of the cursor on the waveform on the display screen, if a movement amount of +5 is input from the input device 1 such as the jog shuttle key or rotary knob, +5 is set as the displacement amount. Will be output.

In this way, the amount of displacement set relative to the amount of movement is made variable depending on the operation target, so that even if the rotation angle of the knob of the input device 1 such as the jog shuttle key or rotary knob is the same, the scroll screen is displayed. When the display is moved, the movement of the display screen is large, and when the cursor is on the waveform of the display screen, the movement of the display screen is small.

Further, even when the diameters of the jog shuttle key and the knob of the rotary knob are different, the definitional expression can be selected in this way, so that the setting of the displacement amount with respect to the movement amount can be easily changed.

A waveform observing device with improved operability can be obtained by also using a digit moving function for designating a numerical value and changing the setting of the numerical value of the digit.

[0021]

According to the present invention, when the conversion formula of the displacement amount with respect to the movement amount is changed for each different operation target and the item whose numerical value can be set is set by the jog shuttle or the like, the setting range of the operation target, Since the setting displacement of the jog shuttle can be changed according to the resolution, setting items with a larger dynamic range can also be set with the setting resolution suitable for it, so you can set with a more natural feeling and operability. Leads to improvement.
