ABSTRACT:
For focusing an image input apparatus before generating a single high-resolution image by the image input apparatus from a plurality of images obtained from an image sensing device by performing pixel shifting operation, first, image data is obtained without performing pixel shifting operation, and a lens unit is moved on the basis of the obtained image data to bring the image input apparatus into focus, then the position of the lens unit is temporarily fixed in the focused state. Thereafter, image data of a plurality of images are obtained in the above focused state by performing pixel shifting operation, then image data of a high-resolution image is generated from the image data of the plurality of images. Further, the lens unit is moved again on the basis of the image data of the high-resolution image to bring the image input apparatus into focus.
