PURPOSE:To surely decide the quantity of the uniform granular material which is optionally dispersed and present with high precision by dividing the number of picture elements of a pattern by the predetermined reference number of picture elements. CONSTITUTION:When the X-directional width and Y-directional width of each pattern in an image are both less than a previously set reference value, it is decided that the granular material does not adhere, but independently present and its quantity is found. When at least one of the X-directional width and Y-directional width of the pattern exceeds the reference value, it is decided that the granular material adheres and the number of picture elements of the pattern is divided by the reference number of picture elements to decide the number of particles of the adhered pattern by a decision device 100. Consequently, the quantity of the uniform granular material which is optionally dispersed and present can surely be decided with high precision as well as whether the material adheres and its number. |
