Patent Images

1. An image processing apparatus comprising:

  • an image input portion receiving (N+1) low-resolution images (where N is an integer of 2 or more);

    a motion amount detector taking one of the (N+1) low-resolution images as a datum image and detecting a amount of motion between the low-resolution image taken as the datum image and each of the other N low-resolution images;

    an image evaluator selecting, based on the detected amounts of motion, M (where M is an integer of 1 or more fulfilling N>

    M) out of the N low-resolution images each as a consulted image; and

    a resolution enhancer producing, based on the detected amounts of motion, the datum image, and the M consulted images, a high-resolution image having higher resolution than the low-resolution images,whereinthe image evaluator takes each of the N low-resolution images as an evaluated image, andwhen an image coordinate system common to the datum image and the evaluated images is called a common coordinate system and, based on the detected amounts of motion, the datum image and the evaluated images are arranged in the common coordinate system,the image evaluatorsets, based on a pixel position on the datum image in the common coordinate system, a datum position in the common coordinate system,evaluates, for each evaluated image, a distance between the datum position and a pixel position on said each evaluated image, andselects, as the consulted image, an evaluated image corresponding to a relatively small distance while excluding, from the M consulted images, an evaluated image corresponding to a relatively great distance.
