Abstract
Provided is a method by which an image forming apparatus forms an image, the method including detecting a boundary area in a portion of image data; determining a direction of the boundary area, a dominant color of the boundary area, and an edge intensity of the boundary area; determining enhancement information with respect to the boundary area based on the direction, the dominant color, and the edge intensity; and forming an image with respect to the image data based on the determined enhancement information.
Claims15
A method by which an image forming apparatus forms an image, the method comprising:
- detecting a boundary area in a portion of image data;
- determining a direction of the boundary area, a dominant color of the boundary area, and an edge intensity of the boundary area;
- determining enhancement information with respect to the boundary area based on the direction, the dominant color, and the edge intensity;
- and
- forming an image with respect to the image data based on the determined enhancement information,
- wherein error diffusion is applied to an area where text is displayed, and dithering is applied to an area where a background of the text is displayed.
An image forming apparatus comprising:
- a network interface that receives data related to a user format document from outside;
- a memory that stores data regarding the received user format document;
- a control unit;
- and
- a printing module that prints the user format document based on determined enhancement information,
- wherein the control unit is configured to detect a boundary area in a portion of image data, determine a direction of the boundary area, a dominant color of the boundary area, and an edge intensity of the boundary area, and determine enhancement information with respect to the boundary area based on the direction, the dominant color, and the edge intensity, and
- wherein error diffusion is applied to an area where text is displayed, and dithering is applied to an area where a background of the text is displayed.
