  • Patent number: 11360606
    Abstract: A control circuit controls a two-wire resistive touch panel. The two-wire resistive touch panel includes a first region and a second region which are adjacent to each other in a coordinate axis direction (X direction), and the first region has resistance per unit length lower than resistance per unit length of the second region. A measurement unit measures an electric signal having a correlation with impedance between two wires which are lead out from the resistive touch panel. A processing unit (i) determines that the first region is touched when the electric signal or the impedance obtained from the electric signal is included in a predetermined first range, (ii) determines that the second region is touched when the electric signal or the impedance obtained from the electric signal is included in a predetermined second range, and generates a touched coordinate.

  • Patent number: 11199932
    Abstract: A touch detection circuit has a first terminal and a second terminal which are respectively coupled to a first electrode and a second electrode located adjacent to each other. The capacitance sensing circuit (i) senses first electrostatic capacitance formed by the first electrode in a space with a periphery including the second electrode, and (ii) senses, by a self-capacitance method, second electrostatic capacitance formed by the first electrode in a space with a periphery in a state where voltage of the second terminal is made to follow voltage of the first terminal. A signal processor detects water over the first electrode and the second electrode on the basis of a difference between the first electrostatic capacitance and the second electrostatic capacitance.

  • Patent number: 7751650
    Abstract: The present invention relates to an image processing apparatus and an image processing program, and an image processing method for making various operations be performed more comfortably. A rotation input section 14 is provided substantially at the center of a mobile phone 1. When the rotation input section 14 is rotated in a clockwise or counterclockwise direction, an image displayed on a display section 13 is rotated to be displayed. In addition, when the rotation input section 14 is pressed at an upper, lower, left or right portion thereof toward inside of the mobile phone 1, a display range of the image displayed on the display section 13 is switched. For example, in a case where a map is displayed, the map is rotated when the rotation input section 14 is rotated, and the map is scaled up/down when a predetermined position of the rotation input section 14 is pressed. The present invention may be applied to mobile phones.
