Title:
磁気データ処理装置、方法およびプログラム
Document Type and Number:
Japanese Patent JP5012252
Kind Code:
B2
Abstract:
In a magnetic data processing apparatus (10), an input part successively inputs magnetic data from a magnetic sensor (11). A first generation part stores samples of the magnetic data (121) in accordance with a first sampling rule, and generates first offset update data (122) based on the stored samples of the magnetic data when a distribution of the stored samples of the magnetic data indicates a first feature. A second generation part stores samples of the magnetic data (123) in accordance with a second sampling rule, and generates second offset update data (124) based on the stored samples of the magnetic data when a distribution of the stored samples of the magnetic data indicates a second feature. An update part (125) updates an offset value (126) of the magnetic data based on the first offset update data when the same is generated, and updates the offset value of the magnetic data based on the second offset update data when the same is generated.
