ENDOSCOPIC IMAGE PROCESSOR AND ENDOSCOPIC IMAGE PROCESSING METHOD

A group of vectors are set to transform each signal of an endoscopic image resolved into a plurality of color signals into a plurality of new color signals based on statistical characteristics of the image. Also, the color signals of the endoscopic image are transformed into new color signals by a matrix operation using the group of vectors for the new color signals. After filtering is applied to the plurality of new color signals, the plurality of new color signals are transformed into a plurality of original color signals by a matrix operation using an inverse matrix of the matrix used in the matrix operation.
