发明名称 Systems and methods for generating high addressability images
摘要 <p>Image systems and methods generate improved high addressability images. The generated image may be input into a printer for printing. An image is processed so that the location of an ink drop in a high addressability image is determined. The location of a printed subpixel, within a pixel, is determined by the magnitude of the grayscale value of an observed pixel, the magnitude of the error that has been previously accumulated, and a predetermined threshold value. The grayscale value of the observed pixel, accumulated error, and threshold value are used to determine a subpixel value. This subpixel value determines how soon another subpixel is fired after a previously fired subpixel. If the subpixel value is low, then another subpixel will be fired relatively soon after the previously fired subpixel. If the subpixel value is high, then the printer will wait a longer time before firing another subpixel. In other words the lower the subpixel value the sooner another subpixel prints. The image generating process may effectively weight the error on neighboring pixels to effectively generate images having both shadow and highlight regions.</p>
