Abstract
A measuring method and apparatus for automatically and accurately measuring the sizes of portions of a hybrid integrated circuit chip and circuit patterns formed thereon or a wiring board and wiring patterns formed thereon. An image of a portion of a hybrid integrated circuit chip or wiring board is obtained through a TV camera which provides image signals representing images including those of objective portions. The image signals are processed to calculate the positions of the objective portions automatically. The size of an arbitrary objective portion is determined from a difference between respective positions of other objective portions.
