1. An image correction device, comprising: an image capturing module comprising an image sensor, the image capturing module being configured for capturing an image of a test chart, the image sensor having a center with coordinates (Xo, Yo), the image comprising a group of black stripes substantially positioned at a center thereof, a center of the group of black stripes being coincident with a center of the image; a first calculating module for calculating coordinates of a center of each black stripe of the group of black stripes; a second calculating module for calculating coordinates (Xc, Yc) of the center of the image based on coordinates of the centers of the black stripes; a third calculating module for calculating a coordinate deviation (ΔX, ΔY) between the center of the image and the center of the image sensor, wherein ΔX=Xc−Xo, ΔY=Yc−Yo; and a correction module for inputting the coordinate deviation (ΔX, ΔY) into the image sensor so that the image sensor corrects the image according to the coordinate deviation (ΔX, ΔY).
