  • Patent number: 11159706
    Abstract: There is disclosed a camera module manufacturing apparatus for joining together a lens unit that incorporates a taking lens and a sensor board to which an image sensor is attached. The camera module manufacturing apparatus includes an optical unit including a collimator lens and a measurement chart for forming an image of the measurement chart on the image sensor through the taking lens. The relative position of the lens unit and the sensor board is adjusted based on an image signal obtained by converting, using the image sensor, an image of the measurement chart that is formed on the image sensor by the optical unit. The measurement chart is disposed to be tilted with respect to a plane that is perpendicular to an optical axis of the collimator lens.
