1. An image processing method, comprising: at a computing device having one or more processors and memory storing programs executed by the one or more processors; obtaining an two-dimensional image; determining a target area on the two-dimensional image, wherein the two-dimensional image includes a background area and a target area, and the background area is an area outside of the target area; detecting a location of the target area on the two-dimensional image; selecting, according to the location of the target area on the two-dimensional image, a default processing manner used to perform blurring processing on pixels of the background area; and performing the blurring processing on the pixels of the background area according to the default processing manner; wherein the detecting a location of the target area on the two-dimensional image comprises: calculating a first deviation factor of a center location of the target area and a center location of the two-dimensional image, wherein the first deviation factor is used to reflect a degree that the center location of the target area deviates from the center location of the two-dimensional image; calculating a second deviation factor of the target area and a boundary of the two-dimensional image, wherein the second deviation factor is used to reflect a degree that the target area deviates from a boundary of the two-dimensional image; judging whether the first deviation factor is smaller than the second deviation factor; determining that the target area is within a first area when it is judged that the first deviation factor is smaller than the second deviation factor, wherein the first area is an area towards a center location of the two-dimensional image; and determining that the target area is within a second area when it is judged that the first deviation factor is equal to or larger than the second deviation factor, wherein the second area is an area towards a boundary of the two-dimensional image.
