摘要
An image processing apparatus includes: an image determining unit configured to determine a gradation value for each predetermined range in input image data; and a screen generator configured to arrange dot images around a plurality of growth centers in a halftone dot screen to form respective dot blocks if an input area rate indicating a ratio of black to white in dot images at the gradation value is smaller than a value at which an image defect occurs, and form bridges to connect adjacent dot blocks during a smallest gradation number if distances between the adjacent dot blocks decrease to a predetermined value or less along with growth of the dot blocks, to form a void halftone dot image.
