1. An image processing method being performed by execution of instructions by a processor of an image processing apparatus, the method comprising: receiving a plurality of consecutive images of an object captured by an image capturing unit of the image processing apparatus, wherein pixels having the same coordinates in each of the consecutive images represent the same part of the object and are regarded as a pixel match; reading all red (R), green (G), and blue (B) values of each pixel match from the consecutive images; analyzing all R, G, and B values of each pixel match to determine a common R value range, a common G value range, and a common B value range of the pixel match, and filtering R values, G values, and B values of the pixel match that respectively fall outside the common R value range, the common G value range, and the common B value range of the pixel match; calculating an average R value, an average G value, and an average B value for each pixel match according to remaining R values, remaining G values, and remaining B values of the pixel match; and creating a new image by taking the average R value, the average G value, and the average B value of each pixel match as color values of a corresponding pixel in the new image.
