Automatic inspection system for camera lenses and method thereof using a line charge coupled device
 An automatic inspection system for camera lenses and method thereof using a line charge coupled device (CCD) which can process a signal easily and perceive a focal distance of lenses exactly by focusing automatically using a modulation transfer function (MTF) method when designing lenses. The automatic inspection system for camera lenses using a line CCD comprises a light source, a chart, a collimator, camera lenses, a mirror, an image pickup part, a signal converter, and a control part.
