An infrared crosstalk compensation method includes capturing an original image of a scene, where the original image includes a plurality of original pixels, the original pixels are arranged in a two-dimensional array according to a first axial direction and a second axial direction, and each original pixel has a red subpixel value, a green subpixel value, a blue subpixel value, and an infrared subpixel value. The method further includes: obtaining compensated values of the red, green, blue, and infrared subpixel values according to the original image, a compensation axial direction, a plurality of red, green, blue compensation coefficients corresponding to the compensation axial direction, and compensation equations; and obtaining a compensated image according to the compensated values of the red, green, blue, and infrared subpixel values.
