  Hereinafter, an operation control method using an electronic apparatus and a touch sensor according to the present invention will be described with reference to the accompanying drawings.

<First Embodiment>
The first embodiment shown in FIG. 1 uses an imaging device as an example of electronic equipment.
In FIG. 1, light from a subject (not shown) is collected by lenses 210 and 230 of the optical unit 2. The optical unit 2 has a diaphragm 220 between the plurality of lenses 210 and 230. Here, only two lenses are illustrated, but generally more lenses are provided. The light condensed by the optical unit 2 is incident on an image sensor 5 such as a CCD. The image sensor 5 converts the incident optical signal into an electrical pixel signal and outputs it to the A / D converter 6.

  The A / D conversion unit 6 converts the input pixel signal into a digital pixel signal and inputs the digital pixel signal to the video signal processing unit 7. The video signal processing unit 7 generates a video signal (for example, RGB signal) of a predetermined format based on the pixel signal input from the A / D conversion unit 6, performs various signal processing, and performs the D / A conversion unit 8 and Output to the face detection unit 9.

  The face detection unit 9 detects the skin color portion of the image based on the video signal input from the video signal processing unit 7 or uses a known pattern recognition technique to detect the person included in the image captured by the subject. A face is detected, and face detection information is output to the control unit 1. The D / A converter 8 converts the input video signal into an analog video signal and outputs the analog video signal to the on-screen display (OSD) superimposing unit 11.

  When there is an input from the user, the touch sensor 13 outputs the operation information to the input processing unit 102 in the control unit 1. As will be described later, the input processing unit 102 performs predetermined processing on the input operation information. For example, a capacitive touch sensor can be used as the touch sensor 13. The touch sensor 13 of FIG. 1 schematically shows a touch sensor.

  The control unit 1 includes a display control unit 101 and an input processing unit 102. For example, a microprocessor can be used as the control unit 1. The control unit 1 may be composed of one microprocessor or a plurality of microprocessors. The display control unit 101 controls the OSD generation unit 10 according to the operation information.

  The OSD generation unit 10 creates an OSD signal based on the control by the display control unit 101, and outputs the created OSD signal to the OSD superposition unit 11. The OSD superimposing unit 11 superimposes the OSD signal input from the OSD generation unit 10 on the video signal input from the D / A conversion unit 8, and supplies it to the display unit 12. The display unit 12 displays a video based on the video signal supplied from the OSD superimposing unit 11.

  Further, the control unit 1 outputs a control signal for driving the motor 3 to the motor driving unit 4 based on the operation information from the touch sensor 13 and the face detection information from the face detection unit 9. The motor drive unit 4 drives the motor 3 based on the control signal input from the control unit 1. The motor 3 is driven by the motor driving unit 4 to move the lenses 210 and 230 of the optical unit 2 and adjust the size of the aperture of the diaphragm 220. As described above, the optical unit 2 changes the focus, the zoom magnification, and the exposure by moving the lenses 210 and 230 and the diaphragm 220. Thus, the optical unit 2, the motor 3, and the motor driving unit 4 serve as zoom means. In this embodiment, as described above, the zoom means using the optical technique is taken as an example, but the zoom means using the electronic technique, the zoom means using the optical technique, and the electronic technique are used. You may use the zoom means combined with the zoom means.

  The configuration and operation of the electronic device of this embodiment will be further described with reference to FIGS. 1, 2A, and 2B. In FIG. 2A, each part other than the display unit 12 and the touch sensor 13 is housed in the housing 100. A display unit 12 and a touch sensor 13 are provided in a monitor unit 60 that can be opened and closed with respect to the housing 100. The touch sensor 13 is disposed adjacent to the display unit 12. The touch sensor 13 has a predetermined size (region) and is divided into four regions 21 to 24 indicated by two-dot chain lines internally. The regions 21 to 24 correspond to the variable resistors 131 to 134 in FIG. When the user's finger 50 touches each area, the resistance value of the variable resistors 131 to 134 changes with the change of the charge stored in the capacitor (not shown), and the voltage value generated at both ends of the variable resistors 131 to 134 changes. To do. The input processing unit 104 can detect the position touched by the finger 50 by detecting the voltage value.

  The display unit 12 displays guide images 201 to 204 that are OSDs together with the image of the subject. In addition, a function when the electronic device (imaging device) operates is assigned to each of the areas 21 to 24. Guide image 201, guide image 202, guide image 203, and guide image 204 indicate functions assigned to region 21, region 22, region 23, and region 24, respectively. Here, the guide images 21 to 24 include characters indicating respective functions, but may be symbols such as icons.

  First, functions assigned to the individual areas 21 to 24 will be described. Here, an operation when the finger 50 touches any of the areas 21 to 24 in a state where the finger 50 is not touching the touch sensor 13 will be described. The functions assigned to the areas 21 to 24 in FIGS. 2A and 2B are an example. The functions assigned to the areas 21 to 24 may be appropriately changed according to the state of the electronic device.

  In FIG. 2A, a zoom function is assigned to an area 25 including an area 21 and an area 22. A telephoto side zoom function and a wide angle side zoom function, which are subordinate functions of the zoom function assigned to the area 25, are assigned to the area 21 and the area 22. The area 23 is assigned a face recognition function, and the area 24 is assigned an automatic exposure function (AE).

  When the finger 50 touches the region 21, the input processing unit 104 in the control unit 1 detects that the finger 50 has touched the region 21 from the change in voltage generated at both ends of the variable resistor 131 of the touch sensor 13. In response to this, the control unit 1 outputs a control signal for setting the zoom to the telephoto side to the motor drive unit 4. The motor drive unit 4 drives the motor 3 based on the control signal input from the control unit 1. The motor 3 is driven by the motor driving unit 4 to move the lenses 210 and 230 of the optical unit 2. In this manner, the optical unit 2 changes the zoom magnification to the telephoto side by a predetermined amount as the lenses 210 and 230 are moved.

  When the finger 50 continues to touch the area 21, the control unit 1 continues to output a control signal for setting the zoom to the telephoto side. Therefore, if the finger 50 keeps touching the area 21, the zoom magnification increases at a predetermined speed until the zoom magnification becomes maximum.

  When the finger 50 touches the region 22, the input processing unit 104 in the control unit 1 detects that the finger 50 has touched the region 22 from the change in voltage generated at both ends of the variable resistor 132 of the touch sensor 13. In response to this, the control unit 1 outputs a control signal for setting the zoom to the wide angle side to the motor drive unit 4. The motor drive unit 4 drives the motor 3 based on the control signal input from the control unit 1. The motor 3 is driven by the motor driving unit 4 to move the lenses 210 and 230 of the optical unit 2. In this manner, the optical unit 2 changes the zoom magnification to the wide angle side by a predetermined amount by moving the lenses 210 and 230.

  When the finger 50 continues to touch the region 22, the control unit 1 continues to output a control signal for zooming to the wide angle side. Therefore, if the finger 50 continues to touch the area 22, the zoom magnification decreases at a predetermined speed until the zoom magnification is minimized.

  When the finger 50 touches the region 23, the input processing unit 102 in the control unit 1 detects that the finger 50 has touched the region 23 from the change in voltage generated at both ends of the variable resistor 133 of the touch sensor 13. In response to this, the control unit 1 causes the face detection unit 9 to start a face detection function. The face detection unit 9 detects the skin color portion of the image based on the video signal input from the video signal processing unit 7 or detects the face of the person 25 included in the subject by using a known pattern recognition technique. The face detection information is output to the control unit 1.

  Based on the face detection information, the control unit 1 outputs a control signal for adjusting the focus to the detected face to the motor drive unit. The motor drive unit 4 drives the motor 3 based on the control signal input from the control unit 1. The motor 3 is driven by the motor driving unit 4 to move the lenses 210 and 230 of the optical unit 2. In this way, the optical unit 2 adjusts the focus to the detected face by moving the lenses 210 and 230. When the finger 50 touches the area 23 again, the control unit 1 causes the face detection unit 9 to end the face detection function.

  When the finger 50 touches the region 24, the input processing unit 104 in the control unit 1 detects that the finger 50 has touched the region 24 from a change in voltage generated at both ends of the variable resistor 134 of the touch sensor 13. In response to this, the control unit 1 outputs a control signal for adjusting the diaphragm 220 to the motor drive unit in order to adjust the exposure according to the condition of the subject (not shown). The motor drive unit 4 drives the motor 3 based on the control signal input from the control unit 1. The motor 3 is driven by the motor driving unit 4 to move the diaphragm 220 of the optical unit 2. In this way, the optical unit 2 adjusts the exposure amount by moving the diaphragm 220.

Next, the operation of the present embodiment including the case where the user traces the touch sensor 13 intentionally or unintentionally will be described using the flowcharts of FIGS.
In FIG. 3, when the power source of the electronic device (imaging device) is turned on, the input processing unit 104 in the control unit 1 starts detecting an input to the touch sensor 13 in step S301. Thereafter, in step S302, the input processing unit 102 determines whether or not the input has been turned on by touching any area of the touch sensor 13 with the finger 50, and if not touched (No), continues the detection operation. .

When the finger 50 touches any area of the touch sensor 13 and the input is turned on (Yes), the process proceeds to step S303. When any area is touched while the finger 50 is not in contact with the touch sensor 13, the touched area is a specific area. In the present embodiment, the specific area is one of the areas 23, 24, and 25.
Although not shown in the flowchart, the input processing unit 104 stores the input area in a memory (not shown). The memory may exist in the control unit 1 or may exist outside the control unit 1. If the memory already stores any area, the storage is updated to the area touched at present.
In step S <b> 303, the control unit 1 causes each unit to perform an operation corresponding to the position touched by the finger 50.

  That is, in step S303, when the finger 50 is touching the region 21 in the region 25, the control unit 1 changes the zoom magnification to the telephoto side. When the finger 50 is touching the region 22 in the region 25, the control unit 1 changes the zoom magnification to the wide angle side.

  In step S303, when the finger 50 is touching the region 23 and the face detection function is currently off, the control unit 1 turns on the face detection function of the face detection unit 9. When the finger 50 is touching the area 23 and the face detection function is currently on, the control unit 1 turns off the face detection function of the face detection unit 9. When the finger 50 is touching the area 24 and the automatic exposure function is currently off, the control unit 1 turns on the automatic exposure function. When the finger 50 is touching the area 24 and the automatic exposure function is currently on, the control unit 1 turns off the automatic exposure function.

  Next, in step S304, the input processing unit 102 determines whether or not the finger 50 has left the touch sensor 13 and the input has been turned off. When the finger 50 is separated from the touch sensor (Yes), the process returns to step S302. When the finger 50 is not separated from the touch sensor 13 (No), the process proceeds to step S305.

  In step S <b> 305, the input processing unit 102 determines whether or not the finger 50 continuously moves from the first touched area while touching the touch sensor 13 and moves to another area. If the finger 50 has not continuously moved from the first touched area (No), the process returns to step S304. When the finger 50 continuously moves from the first touched area (Yes), the process proceeds to step S306.

  Next, in step S306, the input processing unit 102 determines which region of the touch sensor 13 the finger 50 first touched. The area first touched by the finger 50 is an area (specific area) touched in step 302 and is an area stored in a memory (not shown). If the input is to the area 23 or 24, the process proceeds to step S309.

  In step S309, the input processing unit 102 replaces the operation information with the operation information corresponding to the region touched first by the finger 50, not the operation information corresponding to the region to which the finger 50 is currently touching. . As a result, the control unit 1 controls the electronic device assuming that the area where the finger 50 first touches continues. As a result, the control unit 1 does not cause each unit to perform an operation according to the destination area. Thereafter, the process returns to step S304.

  If it is an input to the area 21 or the area 22 in step S306, the process proceeds to step S307.

  In step S307, the input processing unit 102 determines from which area the finger 50 has moved to which area. When the movement of the finger 50 is movement from the area 21 to the area 22 or from the area 22 to the area 21, the process returns to step S <b> 303, and the control unit 1 determines the movement destination of the finger 50 that is the currently touched area. Each unit is caused to execute an operation corresponding to the area.

  In the case of any other movement that is one of movement from the area 22 to the area 23, movement from the area 23 to the area 22, movement from the area 23 to the area 24, movement from the area 24 to the area 23 (other areas In step S308, the input processing unit 102 corresponds to the operation information corresponding to the area touched first by the finger 50, not the operation information corresponding to the movement destination area. Replace with operation information. As a result, the control unit 1 controls the electronic device on the assumption that the area where the finger 50 first touched continues to be touched. As a result, the control unit 1 controls each unit to maintain the current operation. Thereafter, the process returns to step S304.

  In order to perform the control as described above, when the finger 50 first touches the area 21 or the area 22 to which a function related to zoom is assigned, the finger 50 is not related to zoom until the finger 50 is separated from the touch panel 13. Even if the function is shifted to the area 23 or the area 24 to which the function is assigned, the function related to the zoom can be continuously performed.

  In addition, when the finger 50 first touches the region 23 or the region 24, if the finger 50 continues to touch the touch panel 13, other functions do not operate even if the finger 50 is shifted to another region. Therefore, malfunction can be prevented.

  If the finger 50 touches the touch sensor 13 in step S302 (Yes) and the touched area is the area 21 or the area 22, the display control unit 101 in FIG. In this way, the guide image 203 and the guide image 204 may be deleted and only the guide image 201 and the guide image 202 may be displayed. In this case, step S303 includes a step of erasing guide images representing functions assigned to the regions 23 and 24 when it is detected that the region 21 or the region 22 is touched.

Second Embodiment

Correspondingly, the guide images 201 to 204 are displayed so as to be arranged in 2 rows and 2 columns. The rest is the same as the electronic device of the first embodiment.

  In addition, when the region first touched by the finger 50 is the region 22, the display control unit 101 does not display the guide image 203 and the guide image 204 as illustrated in FIG. Instead of this, a guide image having a wide range such as the guide image 212 may be displayed. The processing performed by the control unit 1 including the input processing unit 102 is also changed accordingly.

  When the region first touched by the finger 50 is the region 21 or the region 22, the display control unit 101 does not display the guide image 203 and the guide image 204 as illustrated in FIG. A guide image 221 having a wide range instead of 201 may be displayed, and a guide image 222 having a wide range instead of the guide image 202 may be displayed. The processing performed by the control unit 1 including the input processing unit 102 is also changed accordingly.

  The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the present invention. For example, a configuration may be adopted in which a touch sensor and a display unit are overlapped using a transparent touch sensor. Although various components are controlled by the control unit 1, various components may be controlled by a plurality of control units. In the present embodiment, the touch panel is operated with the user's finger, but the touch panel may be operated with a stick-like object such as a pen.
