摘要： A pulse width modulation technique is disclosed for use in an image forming device such as a laser printer or a photocopier. The technique implements a pacer to synthesize the frequency of a serializer circuit by stretching (or shrinking) pixel pulse train data. The pacer stretches the pixel pulse train data in accord with increment data that is based upon information about the image forming device, such as the number of bits in the pixel pulse train data, the number of bits in print engine pulse train, the target print engine frequency, and the serializer frequency. The technique can be implemented with digital circuits that provide digital test data.

摘要： A 2-pixel averaging unit (101) halves an input image in the subscanning direction, and a multi-level error diffusion unit (102) performs multi-level error diffusion processing. A 2-pixel reconstruction unit (103) replaces each pixel with two pixels adjacent in the subscanning direction. A density value exchange unit (104) exchanges pixel values adjacent in the subscanning direction in each of 2×2 pixel blocks arranged in a checkered pattern in the image after replacement. High-density blocks each serving as a set of high-density dots and low-density blocks each serving as a set of low-density dots can be generated as 2×2 pixel blocks. The exposure region can be concentrated in PWM conversion.

摘要： Since a less-than-one-pixel-basis correction and a one-pixel-basis correction are constantly performed on an image after halftoning, unevenness in density disadvantageously occur depending on a halftoning method. According to the halftoning method, whether the less-than-one-pixel-basis correction is performed on a continuous tone image or the one-pixel-basis correction is performed on a halftone image is switched. The one-pixel-basis correction is constantly performed on the halftone image.

摘要： Setting of growing directions of dots in a dither matrix is facilitated. During defining of the growing directions of the dots corresponding to cells in the dither matrix, a target cell in the dither matrix is defined. When the growing directions of the dots in cells located within a range of one cell from the target cell are not set, the target cell is set as a reference point. When the growing direction of the dot in the cell located at the immediate left or the immediate right of the target cell is set, the growing direction of the dot in the target cell is set based on setting states of the growing directions of the dots in the cells located at the immediate left and the immediate right of the target cell and the reference point.

摘要： An input image analysis unit (100) analyzes the difference value between two pixels adjacent in the subscanning direction in an input image having the first number of tone levels. A vertical resolution conversion unit (101) averages the two pixels to generate average image data. A multi-level error diffusion processing unit (103) performs tone level conversion for the average image data to generate low-level image data. An output pixel selection unit (104) selects two output pixel values for each pixel of the low-level image data based on the analysis result of the input image analysis unit (100), thereby creating output image data having the second number of tone levels.
