An apparatus includes a determination unit configured to determine whether rendering positions of two pieces of rendering data, each representing a semitransparent state by including pixels that are to be rendered by a rendering unit and pixels that are not to be rendered, overlap, and a control unit configured to, if it is determined by the determination unit that the rendering positions of the two pieces of rendering data overlap, perform control such that one of the two pieces of rendering data is not rendered by the rendering unit. Based on the level of the overlap between a plurality of semitransparent objects, the apparatus converts each hatch pattern so that image quality deterioration does not occur.
