Image forming apparatus with image density change portion for gradually reducing image density from an outer periphery of a character toward an inside
摘要：
An image forming apparatus has an image acquisition portion that acquires image data on an image including a character. A character-periphery detector detects the peripheral part of the character in the image data acquired by the image acquisition portion. An outline emphasis portion sets the density of the image data acquired by the image acquisition portion, so that the density of the peripheral part of the character detected by the character-periphery detector becomes higher than the density indicated by this image data. A density changer sets the density of the image data so that this density gradually becomes lower from the peripheral part of the character detected by the character-periphery detector toward the inside thereof. An image former forms an image on a sheet of recording paper on the basis of the image data whose density is set by the outline emphasis portion and the density changer.
摘要（中）：

图像形成装置具有获取包含字符的图像的图像数据的图像获取部。 字符外围检测器检测由图像获取部分获取的图像数据中的字符的外围部分。 轮廓强调部分设置由图像获取部分获取的图像数据的密度，使得由字符外围检测器检测到的字符的周边部分的密度变得高于由该图像数据指示的浓度。 密度变换器设定图像数据的密度，使得该密度从由字符周边检测器检测到的字符的周边部分朝向其内部逐渐变低。 图像显示器基于由轮廓强调部分和浓度变换器设定的图像数据的图像数据，在一张记录纸上形成图像。
