METHOD FOR ADJUSTING POSITION OF IMAGE SENSOR, METHOD AND APPARATUS FOR MANUFACTURING A CAMERA MODULE, AND CAMERA MODULE |
摘要 |
A lens unit and a sensor unit are held by a lens holding mechanism and a sensor shift mechanism. As the sensor unit is moved in a Z axis direction on a second slide stage, a chart image is captured with an image sensor through a taking lens so as to obtain in-focus coordinate values in at least five imaging positions on an imaging surface. An approximate imaging plane is calculated from the relative position of plural evaluation points which are defined by transforming the in-focus coordinate value of each imaging position in a three dimensional coordinate system. The second slide stage and a biaxial rotation stage adjust the position and tilt of the sensor unit so that the imaging surface overlaps with the approximate imaging plane.
