Provided is an environment for providing information for supporting adjustment of the respective parts for positioning. A position detecting apparatus includes: an image processing unit that detects, through image processing, a position of a feature portion from image data imaged and acquired when the feature portion of an object is positioned at the respective target positions by a moving mechanism; a position storage unit that stores the detected positions detected at the target positions in association with the respective target positions; and a display data generation unit that generates data for displaying information related to the detected positions on a display unit. The display data generation unit generates data for displaying the respective target positions and the respective detected positions, which are stored in association with the target positions, in the same coordinate space.
