Abstract:
1. An image capturing method for pattern recognition of a plurality of target positions on an electronic device to align the plurality of target positions, comprising the steps of: mounting the electronic device on a positioning stage; pre-storing coordinates of the plurality of target positions to be aligned; moving the electronic device by the positioning stage relative to a vision system at a uniform velocity for positioning the vision system over the plurality of target positions on the electronic device; while moving the electronic device at the uniform velocity, determining when the vision system is positioned over each of the coordinates of the target positions to view the target position on the electronic device; and capturing an image of each of the target positions on the electronic device with the vision system while the electronic device is undergoing relative motion with respect to the vision system at the uniform velocity without stopping; and using the images of the target positions to align the target positions.
