For a television scanning element with a scanning area, a method of scanning a television image comprises the steps of: scanning the scanning area at a predetermined fine detail picture scanning rate; imaging a fine detail picture of the television image onto a portion of the scanning area; and imaging more than one coarse detail picture of the television image adjacent to the fine detail picture, each coarse detail picture having a size less than the fine detail picture; wherein the imaging combination produces a fine detail image with the fine detail scan rate and a coarse detail image with a coarse detail scan rate, the coarse detail scan rate being a multiple of the fine detail scan rate equal to the number of imaged coarse detail pictures.
