<p>A field of image information is processed with operations on a relatively coarse representation of the full field and with operations on a high resolution representation of only a portion of the full field. The partial results from operations on field portions may be formatted to yield a composite result for the full field. A photographic record of the image information may be read to provide the full-field representation and read again to provide the field-portion representation. This portion-by-portion processing of image information stored on a photographic record enables a computer with comparatively small memory capacity to execute relatively complex image processing tasks.</p> |
