摘要:
An information processing method includes inputting bit information, temporarily storing at least part of the input bit information, and detecting whether the stored bit information coincides with one predetermined feature of plural such predetermined features. Print information for an object pixel which corresponds to a stored bit is modified in a case where coincidence is detected. Modification may include, for example, contour retention in a case where a rectangular portion is detected, line width discrimination, or white line discrimination. In addition, second feature detection can determine that a right-angled portion is not involved, in which case print information is modified only if coincidence is detected with plural predetermined features and a right-angled portion is not detected.

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.

Binary data (VDO) developed to a dot pattern are sequentially stored in line memories (1-9). A processing circuit (43) is constituted by a logic calculation circuit, and determines an edge portion of an image or a halftone image on the basis of 11.times.9 pixel data in shift registers (34-43). When the edge portion of an image is determined, data of a pixel of interest is converted to data that can print a smooth edge portion. Changed data (VDOM) is converted again according to the type of toner. The converted signal is supplied to a laser driver of a printer, and a printing operation is performed by scanning a laser. A resolution setting unit (1700) receives a resolution setting command from an external apparatus (1300), and sets a designated resolution in a printer (1200) according to the resolution setting command. The resolution setting unit (1700) divides one pixel into an optimal number of pixel sections on the basis of the designated resolution, and sets a logic circuit for performing optimal smoothing processing for divided data in a smoothing unit (1018). Bit map development based on code data supplied from the external apparatus (1300), and smoothing processing according to a smoothing logic, are performed.

摘要:
An information recording apparatus capable of contour smoothing by modifying the data of an object pixel based on pixel data in a surrounding area. There is employed a wide reference area, for example 11.times.9 pixels, divided into plural reference areas, all of which are referred to in the modification of the object pixel, and the modification of the object pixel is achieved by dividing the object pixel into plural sub pixels. In this manner the contour smoothing can be achieved in a more natural manner, also in consideration of the curvature of the contour. Also the modification of the object pixel is inhibited if the original image is identified as a halftone image or certain characters, in order to avoid image blurting by such smoothing.

摘要:
A master unit sends a start signal to a slave unit. When receiving the start signal from the master unit, the slave unit sends, to the master unit, a synchronization field that is a data train (pulse signal) indicative of a transfer clock with which the slave unit is able to perform transferring and receiving operations. The master unit sends, to the slave unit, command data in accordance with the transfer clock indicated by the synchronization field sent from the slave unit. In response to the command data sent from the master unit, the slave unit sends, to the master unit, response data in accordance with the transfer clock indicated by the synchronization field. Thus, in a communication system employing a serial data transferring apparatus of the present invention, the master unit establishes the synchronization for the data transfer, while the slave unit is free from a burden of establishing the synchronization for the data transfer. A serial data transferring apparatus is realized which can simplify the structure of the slave unit, cut the total cost, and reduce noise.
