A pattern extracting apparatus extracts a pattern of a desired color from an object containing a plurality of color patterns. In the apparatus, the object is irradiated by light to provide data relating to color components and the data relating to color components are converted into Munsell color data H (Hue), V (Value) and C (Chroma). After that, a pattern of a specific color is extracted from the object based on the Munsell color data.

DETAILED DESCRIPTION It is an object of the present invention to provide a pattern extracting apparatus which is capable of precisely extracting a specific area corresponding to human sense precisely.
According to the present invention, there is provided apparatus for extracting a pattern of a desired color from an object containing a plurality of color patterns.
The apparatus includes a mechanism for irradiating light on the object; a mechanism for detecting the light from the object and for providing data relating to color components; a mechanism for converting the data relating to color components into Munsell color data H (Hue), V (Value) and C (Chroma); and a mechanism for extracting a pattern of a specific color from the object based on the Munsell color data.
Further, according to the present invention there is provided a method for extracting a pattern of a specific color from an object containing a plurality of color patterns.
The method comprises the steps of collecting data relating to color components from the object; converting the data relating to color components into Munsell color data H (Hue), V (Value) and C (Chroma); and extracting a pattern of a specific color from the object based on the Munsell color data obtained in the converting step.
