Patent ID: 8121398

Claim:
An inspection apparatus, comprising: moving means capable of moving in a plane with an object to be inspected mounted thereon; image pick-up means for picking up an image of the object to be inspected in synchronism with the moving means; and image processing means which receives an output to process from the image pick-up means, wherein the image pick-up means includes an image sensor in which two or more linear picture-element arrays are arranged, as two-dimensional picture-element arrays, perpendicularly to a direction of the picture-element array; wherein a direction of the linear picture-element array of the image sensor is inclined at a predetermined angle from a direction perpendicular to a direction in which the moving means moves when the image pick-up means picks up an image of the object to be inspected; and wherein the image processing means processes an output from the sensor of the image pick-up means which is inclined at the predetermined angle to form an image of the object in sampling with a size less than a size of one picture-element of the two-dimensional picture-element arrays.
