ABSTRACT:
A binarizer binarizes a video signal VD1inputted from an A/D converter and a video signal VD2outputted from a line memory using an average luminance value LU fed from a detection window video signal processor as a threshold value, to output a binary pattern BI. A reference pattern generator generates a plurality of reference patterns RA. A first pattern matching angle detector compares the binary pattern BI with each of the plurality of reference patterns RA, to output the angle of the reference pattern RA which matches with the binary pattern BI as angle information PA. A detected isolation point remover4outputs angle signal AN when the angle information PA has continuity.
