20080231876 | IMAGE PROCESSING APPARATUS - An image processing apparatus has a display to display color images and a storage to store color image data. A first preview controller causes the display to display a color preview image based on stored color image data. A character-area extractor extracts a character area from the stored color image data and a color-designation acceptor accepts a designated color newly set in the extracted character area. A second preview controller changes a color of the extracted character area extracted in the preview image to the accepted designated color, and causes a display of the changed preview image. A decision-instruction acceptor accepts an instruction to set the designated color. A color-change processor responds to the accepted instruction by the decision-instruction acceptor to change information representing a color of the stored color image data to allow the color of the extracted character area to be changed to the accepted designated color. | 09-25-2008 |
20080232684 | IMAGE PROCESSING APPARATUS AND COMPUTER-READABLE RECORDING MEDIUM WHICH RECORDS IMAGE PROCESSING PROGRAM - An image processer has an extractor to extract a character area from color image data. A color-difference-value acquirer acquires information about color-difference values in the character area. A color-saturation-value acquirer acquires information about color saturation in the character area. A color-difference-subrange storage stores pre-defined color-difference subranges. A chromatic-region determination section determines the character area as gray when color salutation values fail to satisfy a condition for a chromatic color, and determines the character area as a chromatic region when color saturation values in the character area satisfy the condition. A first color-difference-subrange assignment section assigns a stored color-difference subrange to the character area determined as the chromatic region based on information about color-difference values. A representative-color setup section sets color information about the character area determined as chromatic by using an average of the color-difference values in the color-difference subrange assigned to the character area. | 09-25-2008 |
