US Patent 7652807 Image generating apparatus, image generating method and computer readable medium

An image generating apparatus includes a color correcting unit, a setting unit and an image generating unit. The color correcting unit corrects a drawing color of each image element. When at least one of color components of the corrected drawing color of each image element meets a predetermined condition, the setting unit sets the at least one of the color components to a predetermined value. The image generating unit draws each image element with the drawing color subjected to the correcting and the setting, to generate an image. When the image element, which is to be drawn with the drawing color including the at least one of the color components, is drawn to overlap another image element, the image generating unit draws a color component, which is same as the at least one of the color components, of a drawing color of the other image element without overwriting.
