摘要:
A method of capturing and processing sensed images includes the step of sensing a viewed image to generate a viewed image signal carrying data representing the viewed image. The viewed image signal is communicated to a central processor. A printed data storage device on which optically detectable data representing an image processing program is printed is read to generate a program signal carrying data representing the program. The program signal is communicated to the central processor. The program is executed at the central processor so that the central processor carries out an image processing operation on the viewed image in accordance with instructions carried by the program to generate output image data.

The present invention relates to an ink reservoir for being received within the former of a printer roll. The reservoir includes a first portion defining one or more channels for each providing ink to a respective output port. A second portion is also provided which bears one or more ink bladders for each containing a respective type of ink. In use, each ink bladder is in fluid communication with a respective channel.

A printer controller is provided for controlling an inkjet print head. The controller has an interface for receiving image data, a contone image decoder for decoding continuous tone image data in the received image data, a bi-level decoder for decoding bi-level image data in the received image data, a dithering and compositing unit for scaling the decoded continuous tone and bi-level image data to a resolution of the inkjet print head, dithering the scaled continuous tone image data, and compositing the scaled bi-level image planes with the dithered continuous tone image planes to produce print data, and an output for outputting the print data to the inkjet print head.

An image sensing and printing device includes a housing. An area image sensor is positioned on the housing for sensing a viewed image to be printed on media and for generating pixel data representing the viewed image. A printing mechanism is arranged on the housing. The printing mechanism defines a media feed path and includes a printhead assembly that includes a pagewidth printhead having at least one printhead chip that spans the media feed path. A feed mechanism feeds media along the media feed path so that the printhead can carry out a printing operation on the media. A processor is positioned in the housing. The processor includes processing circuitry. An image sensor interface is connected to the processing circuitry for receiving pixel data from the image sensor, converting the pixel data into an internal format and writing the converted pixel data to the processing circuitry. The processing circuitry is configured to convert the pixel data to print image data. A printhead interface is connected to the processing circuitry for receiving the print image data from the processing circuitry and for providing signals representing the print image data to the printhead so that the printhead can carry out said printing operation to generate a printed representation of said viewed image.

A printing apparatus and a printing method capable of reducing the processing time with relatively low cost is provided. In a printing apparatus and a printing method in which print data is created from received job data in accordance with an indication of a command associated with the job data, execution time of each command associated with the received job data is measured, execution number of times of said each command is counted, one or more command(s) to be subjected to replacement processing is determined on the basis of the acquired execution time and execution number of times of each command, and the one or more command(s) is replaced with other command(s) which can be executed in shorter time compared to the determined command(s).

An image processing apparatus for applying effects to a stored image includes an optical reader. The apparatus includes a feed mechanism for feeding a planar element on which a printed, two-dimensional pattern having a certain resolution is carried, to the reader. The reader has a sensor with a resolution capacity of at least twice the resolution of the two-dimensional pattern and is configured to generate program data represented by the two-dimensional pattern in an external format, the data itself representing an image processing program. A reader interface is connected to the reader to receive the program data from the reader, the reader interface being configured to transform the program data to an internal format suitable for processing. A processor is connected to both the reader and the reader interface to control operation of the reader and the reader interface and to apply the image processing program to the stored image to generate an output image with desired effects.
摘要:
The user needs the skill to select a pixel interpolating process and a gradation converting process and it is difficult to select an optimum process adapted to desired printing quality. In a printing system using a computer system (10), by allowing a factor such as printing paper which exerts an influence on printing quality to be selected (step 400), the printing quality is estimated from the selected printing paper, a proper printing control which is preliminarily made correspond is selected (step 410), and a process is branched so as to execute the selected printing control (steps 420 to 450, steps 460 to 480), thereby enabling an optimum printing control to be performed.
摘要:
A method of managing a printing system in which print jobs are disposed with a print queue, wherein a so-called nullacting objectnull, is provided within the print queue to behave as a separate job, and is operative for specifying one or more system commands, without further specifying a actual print job. When the acting object reaches the top of the print queue, its system command is executed. Examples of such system commands are an interruption of the print queue processing or a change of default printing and/or printer parameters.
