Abstract
A chroma aberration compensation method using sub-pixel shifting for use in a head-mounted display is provided. The method includes the steps of: obtaining image data from a host, wherein the image data includes a left-eye image and a right-eye image; obtaining a refraction characteristics curve corresponding to a left-eye lens and a right-eye lens and calculating a resolution of the image data; calculating a distance and a relative direction between each sub-pixel in each color channel of the image data and a center of the image data; adjusting an offset value of each sub-pixel in each color channel of the image data according to the calculated distance and relative direction; performing a sub-pixel shifting compensation process to adjust a sub-image corresponding to each color channel to generate an output image according to the offset value of each sub-pixel in each color channel of the image data.
