Abstract
An image data processing apparatus is described that prevents the quality of image data from being degraded by pixel quantity conversion. The apparatus includes an analog processor, a quantity converter and a binarization converter. The analog processor quantizes each of the analog element data to generate multiple-state element data, The quantity converter changes the number of plural pieces of multiple-state element data in one line to generate quantity-converted element data. The quantity converter averages at least two adjacent pieces of multiple-state element data to generate an average value as one piece of new multiple-state element data. The quantity converter further selectively outputs the new multiple-state element data and original multiple-state element data as the quantity-converted element data. The binarization converter binarizes the quantity-converted element data to generate binary element data.
