Abstract: An image generation device divides a distorted-image plane into pixel blocks in order to generate a distorted image in consideration of the distortion and chromatic aberration of an eyepiece. In the plane of a source image, the image generation device determines individual RGB sample positions included in the pixel blocks, sets a bounding rectangle containing the individual RGB sample positions, and determines, for example, computation target pixels corresponding to the bounding rectangle. The image generation device calculates the pixel values of, for example, the computation target pixels, interpolates and samples the calculated pixel values, and regards the results of interpolation and sampling as the pixel values of the distorted image.
