Abstract:
An edge detecting method for detecting a group of picture elements which is changing rapidly as compared with its surroundings as an edge from within an image data in which each picture element is composed of N numbers of independent dark and light data of primary colors, respectively, the group of elements together forming an image made up of pixels, comprising he steps of:a weight coefficient generating step for generating N sets of weight coefficients corresponding to said N numbers of dark and light data of each primary color, respectively, the value of each weight coefficient being different for each pixel of the image; anda judging step for judging whether said each picture element is an edge or not based on said N numbers of dark and light data of each primary color and said N sets of weight coefficients;wherein said N sets of weight coefficients generated at said weight coefficient generating step are N sets of weight coefficients for said N numbers of dark and light data of each primary color, respectively.
