Abstract
An image processing apparatus includes a receiving unit that receives an image; a separating unit that separates a first area from the received image; an extracting unit that extracts a second area of a color having a predetermined relationship in the separated first area; an acquiring unit that acquires the characteristic relating to the shape of the extracted second area; a first determining unit that determines whether or not the second area is plain, on the basis of the acquired characteristic; and a second determining unit that determines, as the property of the first area, whether the first area is a continuous-tone area, a plain area, or a composite area including a continuous-tone area and a plain area, on the basis of the ratio of the second area determined to be plain to the separated first area.
