ABSTRACT:
A new method of reading an imager is achieved. The method comprises providing an imager array comprising n rows and m columns where a pair of rows can be read during a single row access time. A first image field is completed by sequentially reading and storing pixel values of pairs of adjacent rows of the imager array. The reading begins at a first row, and the reading stops when less than three rows are unread. Thereafter pixel values of the next row are read and not stored. Thereafter pixel values of the first row of the imager array are read and not stored. A second image field is completed by sequentially reading and storing pixel values of pairs of adjacent rows. The reading begins at the second row, the reading stops when less than two rows are unread.
