Position detection apparatus, position detection method, testing apparatus, and camera module manufacturing apparatus

摘要

There is provided a position detection apparatus for detecting position of an image pickup device that outputs an output signal corresponding to intensity of detected light, having a light source for generating light, an illumination lens for illuminating the light generated by the light source onto the image pickup device, a position detecting section for detecting relative position of the image pickup device with respect to the illumination lens based on the output signal outputted out of the image pickup device corresponding to the light received via the illumination lens and a moving section for changing the relative position of the image pickup device to position set in advance by moving at least one of the image pickup device and the illumination lens based on the relative position detected by the position detecting section.
