Abstract:
An image processing apparatus having functions installed thereon includes a job input portion that inputs a first job, a job storage that stores the first job, a job output portion that outputs the first job, a memory that allows allocating memory areas to the functions and reallocating the memory areas, a first judgment portion that judges whether or not the memory areas were reallocated after input but before output of the first job, a second judgment portion that judges whether or not output of the first job requires any unavailable function, a third judgment portion that judges whether or not the unavailable function will be available by restricting operations related to a second job and by adjusting the memory areas, and an operation restriction portion restricts operations related to the second job and adjusts the memory areas, wherein the first job is output while restrictions on the operations are effective.

Abstract:
A data processing apparatus obtains an input pixel region contained in image data, inputs a pixel value contained in the input pixel region into an image processor, obtains the image-processed pixel value from the image processor, and outputs an output pixel region. Data of the input pixel region and data of the output pixel region are temporarily stored, and the size of an input area that stores the data of the input pixel region and the size of an output area that stores the data of the output pixel region are set based on the number of pixels in the input pixel region and the number of pixels in the output pixel region.
Abstract:
An image joining method for a scanner that scans and transfers image data to a terminal is provided. During scanning and data transfer, when the image data stored in a register is full, an image processor stops the scanning of a linear photodetector. Meanwhile, a matrix photodetector fetches and stores the image of a code strip. Then, the photodetectors are moved backward a distance larger than that being required to be accelerated forward when the scanner resumes scanning. After the data in the register being transferred and cleared, the linear photodetector resumes scanning at a normal moving speed. The code strip image is further fetched and compared with the stored one to get a joining point of scanned image data. By the joining point, the new and prior image data portions are joined and the scanning proceeds, and joined image data will not be overlapped or broken.
Abstract:
A method and system for preliminary data processing before printing is disclosed. The steps executed by said system comprises: dividing a page into a plurality of bands including a Mth band and a (M+1)th band; converting a color format of the Mth band; transferring the Mth band to a printer for storing, and converting the color format of the (M+1)th band in the period of transferring the Mth band; and printing the Mth band, wherein the printing does not start until the printer receives 50%-100% bands. During the printing, the color format of the residual bands continues to convert and the converted residual bands continue to transfer to the printer until the page is finished printing.
Abstract:
A recording apparatus configured to cause a recording head to move and scan in a reciprocating manner includes a buffer configured to store raster data including multivalued data, a table in which a plurality of dot patterns is defined for a value of the multivalued data and including a dot pattern corresponding to the value, a first information storage unit configured to store an initial value of the dot pattern according to a direction of scanning by the recording head and the value of the multivalued data, a second information storage unit configured to store information indicating an empty raster, and a generation unit configured to, based on the initial value stored by the first information storage unit and the table, read the multivalued data from the buffer and generate a dot pattern based on the read multivalued data.
Abstract:
An image-forming system prevents a print overrun error even if there are bands of divided data having different band heights. An image-forming system has a band divider to divide image data into a plurality of bands each containing divided image date, a loader to load the bands into a band memory, and an output unit to sequentially output the bands from the band memory to a print engine at predetermined timing. The band divider can change the height of at least one of the bands from the height of the remaining bands. The band memory includes VRAMs into which a band of bitmap data whose band height is higher than a threshold is loaded and an auxiliary VRAM (VRAM-special) into which a band of bitmap data whose height has been changed.
Abstract:
A recording system and a recording method which can perform the recording operation without increasing an image storage capacity of a recording apparatus even if image data is increased with an increase in a recording resolution. Picture element data of image data is split into a plurality of split picture element data by a specific pattern. The plurality of split image data are transferred with offsetting each of the split picture element data. The offset and transferred split picture element data are held by a storage means. The split picture element data held by the storage means are controlled so as to be recorded on a recording medium at positions where the above-described picture element split processing is not subjected thereto.
Abstract:
An image is recorded by repeating a recording operation which includes a main scanning operation performed by moving a recording head in which recording elements are arrayed in a direction perpendicular to a direction in which the recording elements are arrayed. A vertical scanning operation is performed by moving a recording medium in a direction perpendicular to the horizontal scanning direction through a distance corresponding to a recording width after the horizontal scanning operation is completed. When image data having a width narrower than a maximum recording width of the recording head is recorded, for example when a reduction recording is performed, a number of image data having the narrower width are combined so that image data having the maximum recording width can be recorded in one recording operation using the plurality of recording elements. Consequently, when image data having a width narrower than the maximum recording width of the recording head is recorded, the image quality and the recording speed are improved.
Abstract:
An original reading device reads an image on an original in response to a read command, to produce image data, which is stored into an image memory. An output device performs an output process in which copying onto a sheet is effected based on the image data stored in the image memory and the copied sheet is discharged. A control device supplies the read command to the original reading device, and outputs an output command to the output device at such a timing that the output process of the output device is completed at a time point when the reading of the original by the original reading device is also completed.
