    • A novel image processing system includes a pixel position indicator and a pixel inserting unit. The pixel position indicator is configured to indicate insertion positions in the image data. The pixel inserting unit is configured to enlarge a size of the image data by inserting an additional pixel at each of the insertion positions and accordingly shifting the original pixels in a given direction. The additional pixel has a value lower than a given threshold. Each insertion position is at an approximate center of an area formed of pixels having values higher than the given threshold. A novel image forming apparatus incorporates such an image processing system and an electrophotographic system. The electrophotographic system is configured to form an image by irradiating a photoconductive surface with a laser beam according to the processed image data.
    • 一种新颖的图像处理系统包括像素位置指示器和像素插入单元。 像素位置指示器被配置为指示图像数据中的插入位置。 像素插入单元被配置为通过在每个插入位置处插入附加像素来放大图像数据的大小,并且因此沿给定方向移位原始像素。 附加像素具有低于给定阈值的值。 每个插入位置在由具有高于给定阈值的像素形成的区域的大致中心处。 一种新颖的图像形成装置结合了这种图像处理系统和电子照相系统。 电照相系统被配置为根据处理的图像数据通过用激光束照射光电导表面来形成图像。
