Claim 3:
4. The image acquisition method as claimed in claim 2, wherein filtering the second color original image to acquire the second color filtered image, comprises:
determining a second to-be-filtered pixel in the second color original image;
determining a second reference area in the second color original image, wherein the second to-be-filtered pixel is located in the second reference area;
calculating, for each of a plurality of second reference pixels in the second reference area, a weight for the second reference pixel relative to the second to-be-filtered pixel, wherein the plurality of second reference pixels have a same color channel as the second to-be-filtered pixel, and the weight comprises a weight in a spatial domain and a weight in a range domain;
correcting, according to the plurality pieces of second color original image data of the plurality of second reference pixels and the weights for the plurality of second reference pixels, the second color original image data of the second to-be-filtered pixel to acquire one of the plurality pieces of second color filtered image data; and
traversing each pixel in the second color original image to acquire the plurality pieces of second color filtered image data.
