A novel automatic inspection technique and apparatus is disclosed for differentiating differently colored regions of an object or surface (such as solid state wafers, printed circuit boards, or more general applications for distinguishing regions of one color from their neighboring or surrounding areas of different color), involving the use of at least a pair of separate detectors of light images (CCD cameras preferably) reflected from the object or surface and provided with optical filters of different colors corresponding to the differently colored regions of the object or surface; and an electronic filtering processing by multiplying the detector signals by different weighting coefficients selected to maximize the ratio between the filter responses to optimize signal contrast, and then linearly summing the multiplexed signals. Independence from wide light intensity variations and in color variations in the production or processing of the object is thereby obtained.

Method of and apparatus for object or surface inspection employing

A pattern inspection technique and apparatus, suitable for wafer and printed circuit board and related applications, employing novel intelligent imaged-pattern shrinking and expanding architecture to identify permissible line widths, spacing and in surrounding material context, and to identify defects or errors.

Method of and apparatus for geometric pattern inspection employing

A robotic control system and technique is disclosed involving image sensing of an object to be subjected to robotic action, to obtain analog image signals that are converted into binary image signal matrices which, through the use of a mask algorithm image processor (MAIP), are analyzed, and selected signals thereof corresponding to predetermined portions of the object defining points of interest at which robotic action is to be effected are fed to a computer to control movement of a robotic arm, tool or the like to effect some physical action at said predetermined points of interest of the object, in real time.
