摘要： A multivalued input recording signal is subjected to pulse-width modulation at a time unit shorter than the period of a clock signal within the period of the recording signal. Alternatively, the multivalued input recording signal is converted into a plurality of different signals each of whose length of time is shorter than a clock signal within the period of the recording signal, thereby performing pulse-width modulation in accordance with a predetermined weighting. This makes it possible to obtain a highly toned recording signal without raising the frequency of the clock signal. Further, density tone data is generated in dependence upon inputted multivalued pixel data, and control is performed using both the irradiation time and emission intensity of a light beam based on the generated density tone data. An image is formed by irradiating a photosensitive body with the controlled light beam.

摘要： The present invention is structured in such a manner that, when multivalued pixel data which constitutes a multivalued image are supplied, a predetermined number of interpolated pixel data are generated and inserted between the supplied and successive pixels. At this time, the gradient of each of the interpolated pixels is calculated and determined in accordance with the gradient of the supplied neighboring multivalued pixels. Thus, the image is recorded on a recording medium in accordance with image data including the interpolated pixel. As a result, print information processed so as to be printed by a low resolution printer can be printed with the same size and high quality as when printed by a high resolution printer according to the present invention.
