1. A position detecting method for a touchscreen panel that includes a conductive film divided into a plurality of conductive regions that are electrically insulated from each other, and detects a track of a movement of an object that comes into contact with the touchscreen panel, the position detecting method comprising:

  • determining whether a no-touch state in which the object is out of contact with each of the conductive regions is detected or not, after a first touched state in which the object is in contact with a first conductive region of the conductive regions is detected;

    measuring a duration time between a detection of the no-touch state and a detection of a second touched state in which the object is in contact with a second conductive region of the conductive regions adjacent to the first conductive region and which is detected subsequently to the detected no-touch state, in response to determining that the no-touch state is detected;

    determining whether the second touched state is detected;

    determining whether the measured duration time is less than a predetermined time when the second touched state is detected; and

    outputting a continuous track of the movement of the object that is continuous between the adjacent first and second conductive regions when the measured duration time is less than the predetermined time, and confirming the no-touch state when the duration time from the detection of the no-touch state is longer than or equal to the predetermined time,wherein the touchscreen panel outputs a signal indicating a touched state when the object is in contact with one of the conductive regions,wherein the signal indicating the touched state is continuously output for a certain period which is longer than or equal to the predetermined time after the detection of the no-touch state, andwherein the predetermined time is determined based on at least an interval between the adjacent first and second conductive regions.
