ABSTRACT:
A facial image picture data is processed by an edge extraction part, which performs edge extraction on the inputted image picture. The processed data is then converted by a binary level conversion part for each preestimated point of facial elements. An image picture arithmetic processing part performs time-to-time arithmetic computation of correlation values between the data of the binary-leveled edged-image picture and the data having been previously stored in the shape data-base part, and issues an output including extracted data of feature points of the facial image picture.
