  • Image shake correction device, imaging device, position detection method, position detection program
    Patent number: 10895756
    Abstract: Data sets DS4 to DS6 each consisting of plural linear functions obtained by approximating an output characteristic of a Y-axis rotation position detection Hall element H2 and a data set DS2 consisting of plural linear functions obtained by approximating an output characteristic of an and the X-axis position detection Hall element H1 are stored for each of plural positions in a direction X in a ROM of a memory. A system controller detects a position of a movable member in the direction X based on the data set DS2 and an output signal of the X-axis position detection Hall element H1, then selects the data set corresponding to the position among the data sets DS4 to DS6, and detects a position of the movable member in a direction Y based on the selected data set and an output signal of the Y-axis rotation position detection Hall element H2.
