Claim One:
1. A downsampling based display method comprising: obtaining an input image, wherein the input image comprises a plurality of pixels; obtaining at least two pixels neighboring with a to-be-calculated DS pixel in a target image on each of at least two directions from the plurality of pixels of the input image to obtain at least four first neighboring pixels, and calculating theoretical values of each of the at least four first neighboring pixels on the at least two directions; obtaining errors between the theoretical values of each of the at least four first neighboring pixels and a corresponding original value, and determining weight coefficients for calculating the DS pixel according to the errors; and calculating an estimation value of the DS pixel according to the weight coefficients and a weighted cubic interpolation calculation model built in advance for the DS pixel, using the above steps to calculate corresponding estimation values of the other DS pixels in the target image, and thereby obtaining a downsampling processed image.
