Claim 6:
7. 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 first to-be-filtered pixel in the first color original image and a second to-be-filtered pixel in the second color original image, wherein a position of the first to-be-filtered pixel in the first color filtered image corresponds to a position of the second to-be-filtered pixel in the second color filtered image;
determining a first reference area in the first color original image and a second reference area in the second color original image, wherein the first to-be-filtered pixel is located in the first reference area, and the second to-be-filtered pixel is located in the second reference area;
calculating, for each of a plurality of first reference pixels in the first reference area, a range-domain weight for the first reference pixel relative to the first to-be-filtered pixel, and calculating, for each of a plurality of second reference pixels in the second reference area, a spatial-domain weight for the second reference pixel relative to the second to-be-filtered pixel;
correcting 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, according to the plurality pieces of second color original image data of the plurality of second reference pixels, the range-domain weights for the plurality of first reference pixels, the spatial-domain weights for the plurality of second reference pixels; and
traversing each pixel in the second color original image to acquire the plurality pieces of second color filtered image data.
