摘要： An image synthesizing system is provided which uses an intermediate transfer belt on which a plurality of toner images are superimposed. The image synthesizing system is used for an image processing apparatus which forms a toner image on a recording sheet by using an electro-photographic method. The image synthesizing system comprises a photosensitive drum on which the toner image is formed and an intermediate transfer belt which makes contact with the photosensitive drum so that the toner image formed on the photosensitive drum is transferred onto the intermediate transfer belt. A plurality of toner images are formed on the intermediate transfer belt, each of the toner images being formed on the photosensitive drum in accordance with image data obtained from different image data sources, the toner images being transferred onto the intermediate transfer belt one after another. A command ejection mode can be set by an operator in which an additional image will be superimposed on a first superimposed image. In the command ejection mode, the image generation will be begun by a print command and an ejection command will terminate the command ejection mode. Both the print and ejection command are inputted by an operator via a control panel.

摘要： A digital image processing method includes first through fifth steps. The first step is providing a first matrix pattern having a plurality of threshold values stored in a storage memory. The second step is defining a size of each of second matrix patterns based on a predetermined area of the first matrix pattern. The first matrix pattern is composed of the second matrix patterns each of which includes a partial set of the threshold values and has the defined size so that a line density of an output image is determined. The third step is reading two or more threshold values of one of a plurality of basic matrix patterns from the storage memory at specified addresses. Each second matrix pattern is composed of the basic matrix patterns each of which has two or more threshold values and corresponds to one pixel. The fourth step is comparing the digital image data relating to one pixel with the threshold values of the basic matrix pattern to produce a multilevel image signal based on the comparison result. The fifth step is outputting the multilevel image signal relating to one dot, so that each dot is represented by a plurality of tone levels determined by each basic matrix pattern.

摘要： A direct memory access device has an increment counter for indicating an address increment between succeeding transfer blocks of data from a first storage location to a second storage location within a memory device. Each block of data has a lateral width determined by the content of a line byte counter associated with both the source and destination areas of the memory device. After the transfer of each block of data, the address is advanced by an amount corresponding to the content of the increment counter. The direct memory access device is capable of multi-dimensional data transfers; for example, two- and three-dimensional transfers.

摘要： An image output system includes a memory for storing multi-level information which describes each pixel of a binary image when the binary image is scanned in a main scanning direction, where the multi-level information has a first value at a black transition point where a pixel changes from white to black and has a second value at a white transition point where a pixel changes from black to white, a counter for keeping a count, a decoder for decoding the multi-level information read out from the memory, where the decoder outputs a value indicating black when the count of the counter is greater than or equal to one, and a controller for controlling an operation timing of the decoder in synchronism with reading of the multi-level information from the memory. The controller scans the memory to read the multi-level information from the memory and supplies the read multi-level information to the decoder. The decoder increments the count of the counter by one when the multi-level information has the first value and decrements the count of the counter by one when the multi-level information has the second value.

摘要： A pattern pitch adjustment is applied to dot matrix pattern data as it is output from a CPU to a printer. The data is transferred from a DMA to the printer bit by bit, and the number of synchronizing signals output from the printer for each bit is counted to decide picture element timing. During a given period of time after transferring each data pattern, a waiting signal is applied to the DMA so that space picture element data is fed to the printer.

摘要： A halftone image processing method for providing image information in a bit distribution by specifying a matrix pattern in response to tone data which is indicative of a recording density. Several matrix pattern groups are prepared each comprising matrix patterns which are larger in number than dots which define a dot matrix. The matrix pattern groups are provided with density characteristics different from each other. One of the groups is specified in conformity to a required density characteristic, while one of the matrix patterns in the specified group is specified in response to tone data. Any one of various modes of tone representation is selectable and, in addition, numerous tones may be rendered to enhance smooth representation of tones.

摘要： A mother matrix pattern as a fixed matrix pattern is specified with gradation data, and information in an area of the specified mother matrix pattern in accordance with the instructed magnification is extracted as information of a child matrix pattern so as to obtain image information with the child matrix pattern being allocated to the gradation data. Plural types of mother matrix patterns are prepared and one of them is specified in accordance with the instructed magnification. For example, at small instructed magnifications, the mother matrix pattern having recording (display) dots dispersed as widely as possible over the entire pattern is specified and used for conversion of the gradation data, while at larger instructed magnifications, the type of the mother matrix pattern is specified to match characteristics of the image.

摘要： An image data compression system detects from an input image data a transition edge of a picture element on a scanning line where the picture element undergoes a transition from white to black or vice versa. A direction change quantity between a direction of a transition edge of a picture element on an object scanning line and a direction of a transition edge of a picture element on a reference scanning line which precedes the object scanning line is detected, and this direction change quantity is coded into a directional change code which is output as a compressed image data of the input image data.
