Description

  The present invention relates to an input device, and more particularly to a stylus input device including a main body device such as a computer main body and a portable electronic device main body having a touch panel or a touch pad, and a stylus pen.

  In electronic devices such as computers, mobile phones, and PDAs, electronic devices equipped with a so-called touch panel type input device in which a transmissive pointing device is bonded to a display device have become widespread. In these devices, when a figure or the like displayed on the screen is operated with a stylus pen or a finger, the pointing device detects the operation and receives an instruction to the device.

  Conventionally, this type of input device has a pressure-sensitive input device (pointing device) and is configured to select a graphic object already displayed on the screen in accordance with the pressing pressure of the stylus pen. (For example, refer to Patent Document 1). According to this, when the stylus pen is brought into contact with the screen on the screen and the pressing pressure is gradually increased, a circular selection area is displayed on the screen from the time when the predetermined pressure is exceeded. Thereafter, the selection area is enlarged or reduced in accordance with the pressing pressure, and the graphic object already displayed on the screen can be selected.

  In addition, in a planar coordinate input device (pointing device), when a so-called tap operation is performed, a graphic displayed on the screen is enlarged and displayed (for example, see Patent Document 2). . According to this, when a tap operation is performed on the screen, a graphic displayed in the vicinity of the position where the operation is performed is enlarged and displayed at a predetermined position at a predetermined magnification. be able to.

Since the enlarged image centered on is superimposed on the original image and displayed, the enlarged image at the indicated position can be easily confirmed. Also, when the operator moves the stylus pen while touching the screen, the display area of the enlarged image moves following the point where the stylus pen is touching, so that it looks as if the loupe is being operated. The enlarged image at the arbitrarily designated position can be easily confirmed.

  Further, according to the input device of the second embodiment, when the pressure for pressing the stylus pen is increased or decreased, the enlargement ratio of the image is increased or decreased according to the pressure. An enlarged image of the area can be easily confirmed.

  Furthermore, according to the input device of the second embodiment, when the stylus pen is pressed and a knock is generated, the entire screen is enlarged centering on the indicated position. The center position for enlarging the image inside can be easily determined, and the entire screen can be enlarged based on the center position.

In the first and second embodiments, the enlarged display area is circular as shown in FIGS. 4 and 7, but other than this, it may be rectangular, polygonal, elliptical, or other shapes. . Further, although the enlarged display area is displayed with the contact position of the stylus pen as the center, the contact position of the stylus pen and the center point of the enlarged display area are shifted as shown in FIG. It may be displayed. Further, as shown in FIG. 8B, the image may be displayed at a position in contact with the contact position of the stylus pen.
In the first and second embodiments, the first knock is the knocking operation. However, the second knock may be the knocking operation. Furthermore, the occurrence of the first knock and the second knocking may be performed. A threshold value may be provided so as to determine whether or not to execute the above-described enlargement processing operation for the entire screen according to the length of the occurrence time interval.

  In the first embodiment, the correspondence table between the pressing pressure and the enlarged display area size is held in four stages as shown in FIG. 3, but may be held in a smaller or more stages.

  In the second embodiment, the pressing pressure / magnification ratio correspondence table is held in four stages as shown in FIG. 6, but it may be held in a smaller or more stages.

  In the present invention, when an operator presses a point on the screen using the stylus pen, the enlarged image is displayed so as to be superimposed on the original image around the pressed point. Can be easily confirmed. Also, when the operator moves the stylus pen while touching the screen, the display area of the enlarged image moves following the point where the stylus pen is touching, so that it looks as if the loupe is being operated. The enlarged image at the arbitrarily designated position can be easily confirmed. Therefore, it is useful as an input device such as a stylus input device including a main device and a stylus pen.

  Further, according to the present invention, when an operator presses a point on the screen using the stylus pen, an enlarged image in a range based on the pressing pressure is displayed on the original image with the pressed point as a center. Therefore, the enlarged image at the designated position can be easily confirmed. Also, when the operator moves the stylus pen while touching the screen, the display area of the enlarged image moves following the point where the stylus pen is touching, so that it looks as if the loupe is being operated. The enlarged image at the arbitrarily designated position can be easily confirmed. Therefore, it is useful as an input device such as a stylus input device including a main device and a stylus pen.

  Further, according to the present invention, when an operator presses a point on the screen using a stylus pen, an enlarged image centered on the pressed point is superimposed on the original image at an enlargement rate based on the pressing pressure. Therefore, the enlarged image at the designated position can be easily confirmed. Also, when the operator moves the stylus pen while touching the screen, the display area of the enlarged image moves following the point where the stylus pen is touching, so that it looks as if the loupe is being operated. The enlarged image at the arbitrarily designated position can be easily confirmed. Therefore, it is useful as an input device such as a stylus input device including a main device and a stylus pen.
