Abstract
A relocation detection unit includes: an acceleration sensor adapted to detect acceleration generated in the apparatus, an arithmetic section adapted to obtain a first calculation value by performing Nth-order integration on detected value of the acceleration sensor at a predetermined timing, wherein N is a predetermined positive integer, a correction section adapted to obtain a second calculated value by adding/subtracting a specific value to/from the first calculation value at the predetermined timing, and a detection section adapted to detect that the apparatus has been relocated if the second calculated value exceeds a preset reference value.
