Title:
画像処理装置、画像処理方法、画像処理プログラム及び記録媒体
Document Type and Number:
Japanese Patent JP5097574
Kind Code:
B2
Abstract:
An image processing apparatus has a plurality of image processing modes and outputs images of a plurality of pages on a single page in a combined manner. An image determining unit (21) determines whether each of the images is a color image or a monochrome image. A character identifying unit (22) identifies a black character area in each of the images. A color-conversion processing unit (25, 32) performs either one of a color conversion and a monochrome conversion on each of the images and a monochrome conversion on the black character area. A mode identifying unit identifies a current image processing mode. When the image determining unit (21) determines that the images include a color image, a control unit (7) controls the color-conversion processing unit (25, 32) to perform the color conversion on the images based on a result of determination by the image determining unit (21) and the current image processing mode. An image output unit combines the images on which the color conversion is performed by the color-conversion processing unit (25, 32) on a single page and outputs combined images.
