Claim Text:
1. A touch panel system, comprising: a touch panel for outputting an output signal in accordance with a presence or absence of an indicator that is in contact with or close to a detection surface; and an indicator position detection circuit configured to detect a position of the indicator within the detection surface based on the output signal outputted by the touch panel, wherein the indicator position detection circuit detects the position of the indicator within the detection surface by use of a detection reference that is set for each predetermined position within the detection surface, the touch panel includes a plurality of drive lines which are provided in parallel to each other along the detection surface, and are each driven by being given a predetermined drive signal, and a plurality of sense lines which are provided in parallel to each other along the detection surface so as to intersect with the drive lines, and each output the output signal in accordance with a capacitance that is formed between a sense line and a drive line by driving of the drive line, and the detection reference that is set for each predetermined position within the detection surface corresponds to an uneven distribution of a thickness of at least part of a member constituting the touch panel within the detection surface due to an undulation in a surface of the at least part of the members constituting the touch panel.
