Abstract
A position detecting device includes a detector circuit detecting a detection signal including information on a position of a magnet from a coil disposed in a housing and opposing the magnet, which is disposed in a lens barrel; and a control circuit converting the detection signal into a count value, determining a conversion formula based on the count value and a velocity of change in the count value, and detecting a position value using the determined conversion formula.
