Patent ID: 7148924

Claim:
An image processing method for processing electronic data of an input image, comprising: a signal separation step of separating the electronic data into R, G, and B color components; an edge amount calculation step of calculating the R edge amount, the G edge amount, and the B edge amount for each of the color components provided at said signal separation step; a maximum edge amount selection step of selecting the maximum edge amount from among the R edge amount, the G edge amount, and the B edge amount calculated at said edge amount calculation step; an edge information calculation step of calculating edge information of the component corresponding to the maximum edge amount based on the maximum edge amount selected at said maximum edge amount selection step; and an electronic data processing step of processing the electronic data based on the edge information calculated at said edge information calculation step, wherein at said maximum edge amount selection step and said edge information calculation step, the maximum edge amount is selected and the edge information of the component corresponding to the maximum edge amount is calculated for each of pixels of the input image.
