发明名称 Image processing apparatus and method for generating an image signal for gradation
摘要 An image processing apparatus includes a receiving section, an edge detection section and a screen processing section. The receiving section receives image information. The edge detection section detects an edge area from the image information received by the receiving section. The screen processing section performs a screen process, which is based on area coverage modulation, for the image information on a basis of the detection result by the edge detection section. The screen processing section performs a screen process for the edge area detected by the edge detection section with (i) a screen angle, which is equal to that of a screen process performed for a non-edge area other than the edge area, and (ii) a number of lines per inch, which is an integer multiple of that of the screen process performed for the non-edge area.
