Image processing apparatus, image processing method, and storage medium that determine whether a white character exists inside a graphics object and convert density information accordingly

摘要

An image processing apparatus includes a determining unit to determine whether or not a white character exists inside a graphics object. In a case when recording material saving processing is instructed and the determining unit determines that the white character exists inside the graphics object, a conversion unit converts the character so as to increase the density thereof and converts a region other than the character inside the graphics object so as to decrease the density thereof. An image forming device forms an image based on the conversions performed by the conversion unit.

主权项

1. An image processing apparatus comprising:
(A) a memory configured to store a control program for recording material saving processing; and (B) a CPU for executing the control program stored on the memory, thereby realizing the following units:
(a) a determining unit configured to determine (i) whether or not a white character exists inside a graphics object and (ii) whether or not the graphics object overlaps with other objects, wherein a region inside the graphics object other than the white character is an inner region; and(b) a conversion unit configured, in a case when the determining unit determines that the white character exists inside the graphics object, (i) to change a color of the white character in order to improve visibility of the white character and (ii) to convert the inner region so as to decrease the density of the inner region, andin a case when the determining unit determines that the graphics object overlaps other objects, the conversion unit is further configured one of (i) to change a color of the inner region to be transparent and (ii) to convert the inner region so as to decrease the density of the inner region, based on an input specified by a user.
