ABSTRACT:
In an apparatus for simultaneously extracting various types of projection features of an image such as a character or any other figure, an image whose projection features are to be extracted is optically multiplied by a multiplier (4) to form a plurality of optical image each having a substantially identical shape, and the plurality of images are independently supplied to a plurality of detecting means (5A) to simultaneously obtain the various types of projection features. The arrangement of the apparatus can be simplified at low cost, and at the same time, parallel extraction of the projection features can be achieved within a short period of time. Various types of projection features can be simply obtained as needed.
