1. A disease diagnosing method adapted to obtain physiological information related to a disease according to a color change of a body skin, wherein the disease diagnosing method comprises:
obtaining continuous images of the body skin, and generating a time domain signal according to an average pixel value of a region of interest in each frame of the continuous images;
transforming the time domain signal to a frequency domain signal, and combining the time domain signal and the frequency domain signal to a time frequency signal;
retrieving a plurality of first features of a first high dimensional space of the time frequency signal to obtain a plurality of second features of a second high dimensional space according to the plurality of the first features, wherein a dimension of the first high dimensional space is greater than a dimension of the second high dimensional space; and
using the plurality of the second features as feature vectors to map to a high dimensional feature space, and classifying the plurality of the second features as one of a plurality of categories of the disease corresponding to the region of interest in the body skin according to a hyperplane of the high dimensional feature space.
