TEXTURE MEASURING METHOD AND TEXTURE CONTROL METHOD

摘要

A texture measuring method which picks up an image produced by rays of light emitted from a light source and passed through a sheet of paper having a required area with a camera, displays the image as a transmission light image on a display of an image processor, performs image processing on the transmission light image displayed on the display so as to determine a texture coefficient and to quantify the texture, and optimizes a J/W ratio or the like by fuzzy control using a membership function on the basis of the texture coefficient thus obtained in order to improve the texture.
