Tilt Calculation Device And Tilt Calculation Method

摘要

An object of the present invention is to provide a tilt derivation device and a tilt derivation method, capable of accurately deriving a tilt of a pointer. In the tilt derivation device for deriving a tilt of a pointer having a pen shape, the pointer includes a first electrode at one end of an axis and a second electrode around the axis. The tilt derivation device includes: a sensor of a plane shape configured to detect positions of the first and second electrodes; and a control portion (10) including a lookup table (15) in which a correspondence relationship between a tentative value of a slope direction tilt and a compensation value is registered, wherein the slope direction tilt is a tilt of the axis toward a slope direction that the axis is inclined from a normal direction perpendicular to the sensor, a slope direction tilt calculation portion (14) calculating the tentative value based on the positions of the first and second electrodes and inputting the tentative value into the lookup table (15), and a tilt derivation portion (16) deriving the tilt from the compensation value outputted from the lookup table (15).
