Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Therefore, the description of the present embodiment does not limit the contents of the invention described in the claims.

<Embodiment>
Embodiments of the present invention will be described with reference to FIGS.

<Schematic configuration of main device control parameter selection device>
As shown in FIG. 1, the control parameter selection device of the main device according to the present embodiment mainly includes electrodes 110 </ b> X, 120 </ b> X, 110 </ b> Y, 120 </ b> Y and a display panel (display area) 200.

  The electrodes 110X, 120X, 110Y, and 120Y are disposed on the outer periphery of the display panel (display region) 200, and the electrodes 110X and 120X are provided on the upper and lower portions of the outer periphery of the display panel (display region) 200 in the X-axis direction. The electrodes 110 </ b> Y and 120 </ b> Y are provided at the upper and lower portions in the Y-axis direction on the outer periphery of the display panel (display region) 200.

  The electrodes 110X, 120X, 110Y, and 120Y are used, for example, in a method for detecting the proximity state of an operator's hand based on a change in capacitance, and in particular, are electrodes used in a method called a self-capacitance method. is there. The detection method will be described later.

  The display panel 200 is preferably a flat panel such as an LCD (Liquid Crystal Display), for example. In this embodiment, operation items such as an air conditioner, an audio device, a navigation device, and operation parameters thereof (if an air conditioner, a temperature is used). In the case of audio equipment, such as CD, DVD, FM, AM, volume, equalizer, etc., in the case of navigation equipment, addresses, telephone numbers, history information, etc.) are displayed in a matrix.

<Electrical configuration of main device control parameter selection device>
As shown in FIG. 2, it includes a capacitance detection unit 310, a proximity detection unit 320, a threshold storage unit 330, a control unit 340, and a display control unit 350.

  The capacitance detection unit 310 detects the amount of change (increase) in the capacitance of each electrode 110X, 120X, 110Y, 120Y. For example, the proximity detection unit 320 compares the amount of change (increase) in capacitance detected by the capacitance detection unit 310 with the threshold stored in the threshold storage unit 330 to detect the proximity state. For example, the proximity value is detected by converting the capacitance value into a voltage value and comparing the two in the form of voltage.

  The control unit 340 outputs a signal for changing the display to the display control unit 350 based on the output signal from the proximity detection unit 320, and the display control unit 350 controls the display of the display panel 200 based on the input control signal. To do.

  Specifically, when operation items such as an air conditioner, an audio device, a navigation device, and the operation parameters thereof are displayed in a matrix form on the display panel 200, for example, the proximity detection unit 320 is in a proximity state to the electrode 110Y. When the proximity state to the electrode 120Y is detected after the detection, the control unit 340 determines that the operation item selection mode such as an air conditioner, an audio device, and a navigation device is selected, and the proximity detection unit 320 approaches the electrode 110Y. After detecting the state, each time the proximity state to the electrode 120Y is detected, a control signal is output to the display control unit 350 so that the operation items are scrolled frame by frame, and the display of the display panel 200 is changed.

<Principle of detection of proximity condition of detected object in control parameter selection device of main device>
The detection principle of the proximity state of the detection object in the control parameter selection device of the main device according to the present embodiment will be described with reference to FIGS.

  As described above, in the self-capacitance method used in this embodiment, an electrode having a stray capacitance is used. The stray capacitance is affected by the parasitic capacitance between the electrode and the surrounding conductor. Since the human body is also a conductor, the value of the stray capacitance increases when a finger (human body) approaches the electrode (see FIG. 3). That is, in the self-capacitance method, the proximity state of the detection target is detected by detecting the capacitance value that increases as the finger (human body) approaches the electrode.

  An example of a method for detecting the proximity state of the detection target will be described with reference to FIGS. 4 and 5.

  FIG. 4 shows an example of the detection circuit. As shown in this figure, the detection circuit includes a capacitor Cc, a measurement capacitor Cx, a comparison capacitor Cr, a resistor Rc, switches SW1, SW2, and SW3, and a comparator.

  The measurement capacitor Cx has one end grounded and the other end connected to one end of the comparison capacitor Cr and the comparison input terminal of the comparator via an electrode. A switch SW1 is provided between the comparison input terminal of the comparator and the ground.

  One end of the capacitor Cc is grounded, the other end is connected to one end of the resistor Rc, and the other end of the resistor Rc is connected to a comparison capacitor Cr and a connection point between the switches SW1 and SW2. The other end of the switch SW1 is connected to the power supply voltage Vcc, and the other end of the switch SW2 is grounded. Further, Vref is connected to the reference voltage terminal of the comparator. Here, the voltage across the capacitor Cc is Vc, the voltage across the measurement capacitor Cx is Vx, and the voltage across the comparison capacitor Cr is Vr.

  In this method, the capacitance of the electrode measurement capacitance Cx is measured as follows. That is, electric charge accumulates in the capacitor Cc and gradually discharges through the resistor Rc. The electric charge of the capacitor Cc moves to the comparison capacitor Cr and the measurement capacitor Cx. Therefore, the capacitance of the electrode measurement capacitance Cx is measured by detecting the voltage divided by the comparison capacitor Cr and the capacitor Cc.

  The detailed measurement method is as follows: 1) The switch SW1 is turned on and electric charge is accumulated in the capacitor Cc. At this time, the switches SW2 and SW3 are in the OFF state. 2) All the switches SW1, SW2, and SW3 are turned off to maintain the charge of the capacitor Cc. 3) Turn on the switches SW2 and SW3 for a predetermined time. Then, while all the charges of the measurement capacitor Cx and the comparison capacitor Cr are discharged, a part of the charge of the capacitor Cc is discharged through the resistor Rc. 4) Turn all the switches SW1, SW2, and SW3 to OFF. At this time, the electric charge of the capacitor Cc moves to the measurement capacitor Cx and the comparison capacitor Cr. 5) The voltage (Vx) of the measurement capacitor Cx is compared with Vref by a comparator.

  FIG. 5 shows an equivalent circuit of the above 4) and 5). Here, since the comparison capacitor Cr, the measurement capacitor Cx, the voltage of the capacitor Cc, Vr, Vx, and Vc must be equal, the charge of the capacitor Cc is dispersed in the measurement capacitor Cx and the comparison capacitor Cr.

  The relationship between the voltages Vr, Vx, and Vc and the capacities of the comparison capacitor Cr, the measurement capacitor Cx, and the capacitor Cc is expressed by the following equations 1 to 3.

  The above 3), 4) and 5) are carried out until the condition of Vx <Vref is satisfied. Here, as shown in Equation 3, when the capacitance Cx is increased, the number of discharge cycles until the condition of Vx <Vref is satisfied is reduced as shown in FIG. Therefore, the proximity state can be detected by counting the number of discharge cycles.

  Accordingly, when the proximity state of the detection target is detected in the electrode 120Y after the proximity state of the detection target is detected in the electrode 110Y, it is determined that the detection target has moved left and right, and the detection target is detected in the electrode 110X. After detecting the proximity state of the detection body, when the proximity state of the detection body is detected at the electrode 120X, it is determined that the detection body has moved up and down. For example, when the proximity state of the detection object is detected in the order of the electrode 110Y, the electrode 110X, the electrode 120Y, the electrode 120X, and the electrode 110Y, it is determined that the detection object has moved in a circular shape clockwise. When the proximity state of the detection object is detected in the order of 110Y, the electrode 120X, the electrode 120Y, the electrode 110X, and the electrode 110Y, it is determined that the detection object has moved clockwise in a circular shape. In addition, an upper semicircle and a lower semicircle can be identified.

<Display Mode in Control Parameter Selection Device of Main Device>
A display form in the control parameter selection apparatus of the main apparatus will be described with reference to FIGS.

Specifically, the volume display of VOL16, VOL17, VOL18, VOL19, VOL20, etc. is scrolled horizontally one frame at a time, and when the scroll display of all operation parameters on this line is finished, the lower line, that is, AUX, PC functions such as USB and operation parameters such as CD / DVD, FM, and AM are scrolled horizontally one frame at a time. When all the operation parameters on this line have been scrolled, the process moves to the lower line. If it is detected that the operator's hand has moved left and right after scrolling to the bottom line, the selection process may be reset. In this embodiment, an example in which the initially displayed operation items and operation parameters are scrolled is shown. However, not only the operation items and operation parameters that are initially displayed, but also operation items and operations that are not initially displayed. The parameter may be scrolled. Further, the initial display of operation items and operation parameters may be set freely by the operator.

  Then, when the operation parameter to be operated by the operator is scrolled to the line in which the confirmed action item is displayed (gray portion in FIG. 9), the hand action is stopped, as shown in FIG. In addition, when the operator holds the palm close to the surface of the control parameter selection device of the main device according to the present embodiment (the capacitance detection unit 310 sets the capacitance within a predetermined range for all the electrodes). Detection), the action item and the operation parameter are finally determined. In the present embodiment, an example has been described in which the action item and the operation parameter are finally determined when the operator holds the palm of the hand.
