IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

An image processing device according to one embodiment includes an acquisition unit, a first specifying unit, and a second specifying unit. The acquisition unit acquires an edge between a text region where the translucent text is superimposed and a background region where the translucent text is not superimposed. The first specifying unit acquires a plurality of pairs of a representative color in the text region and a representative color in the background region adjacent to each other with the edge placed therebetween, and specifies a text color and transparency of the translucent text from the plurality of pairs. The second specifying unit specifies a pixel color before the translucent text is superimposed for each pixel in the text region from a pixel color after the translucent text is superimposed, the text color and the transparency.
