Definitions
- the present invention is especially relevant to high-volume, digital franking machines that allow users to conveniently place postage inidicia on mail. More generally, however, the present invention is relevant to multi-tasking systems where the system processor is normally taxed with many functions, including downloading a print map for, and controlling printing or other reproduction operations.
- High-speed digital franking machines such as those marketed by Ascom Autelca AG, the assignee of the present Letters Patent, are apparatuses that allow a postal customer to both rapidly determine the correct postage for a high volume of mail items, and to affix a postage indicia on the mail item in an automated or semi-automated manner. Determining the correct postage can involve such steps as weighing the mail, sizing the mail, and determining the mail destination.
- the general components often include: an initial feeder for individually feeding pieces of mail into the machine, a weighing machine for weighing each piece of mail; a user interface for monitoring and controlling the operation of the machine and for entering data as needed, a postage calculator for calculating the correct postage for each piece of mail; a postage affixer for affixing indicia representing the correct postage on each piece of mail; and a machine discharger for discharging the mail from the machine.
- the postage may be printed on a sticker and then affixed to the flat (e.g., envelope, postcard, etc.) or parcel, or it may be printed directly onto the mail.
- An increased demand for franking machines is partly due to the willingness of various postal authorities to allow private parties to generate their own postage indicia, provided there are secure methods for payment, authentication, fraud prevention and the like.
- Such a system includes the United States Postal Service's Information-Based Indi- cia Program (IBIP).
- the system processor and system bus may handle many tasks that may cause "bottlenecks." Because calculations may be needed to determine the correct postage, and because rapidly moving mail needs postage stickers and regions to be quickly produced, the system buses of prior art high-speed franking machines are often taxed to their limit, causing delays in the franking process or a reduction in the overall franking speed. The same delays and bus bottlenecking observed for high-speed franking machines are often observed for other operations unrelated to franking, where images are output or reproduced will the system processor must simultaneously perform other tasks which determine the content of the images.
- a prior art system 100 that suffers from the aforementioned limitations is generally and schematically illustrated in Figure 1.
- a system processor (labeled “microproces- sor”) 110 controls the system operation, and performs major computational tasks.
- the system processor 110 is connected to a number of components, including a Random Access Memory (RAM), which may be more appropriately called a Read and Write Memory 130 (via a bus line 120), and to the print head 150 of a printing device (via control lines 140).
- Figure 1 also shows that the RAM 130 is capable of transferring information to the print head 150 (via bus line 160) under the direction of the system processor 110.
- the lines 120, 140 and 160 can be considered to be part of the system bus.
- the present invention provides a method of converting and reproducing in a sequential manner, a digital image.

Abstract
A method and system for outputting and reproducing information representing a digital image alleviates system bus bottlenecks by downloading image information from the RAM (Figure 2, 230) to an Application Specific Integrated Circuit (ASIC) (Figure 2, 280), download controlled by the ASIC (Figure 2, 280), and allowing the ASIC (Figure 2, 280) to directly interface with and directly control the operation of an output device (Figure 2, 250). The ASIC (Figure 2, 280) and the output device (Figure 2, 250) are directly connected thereto via a dedicated bus (Figure 2, 290). While the ASIC (Figure 2, 280) downloading image information from the RAM (Figure 2, 230), the system processor (Figure 2, 210) performs calculations needed from certain portions of the image prior to output and reproduction.

1. Field of the Invention The present invention is especially relevant to high-volume, digital franking machines that allow users to conveniently place postage inidicia on mail. More generally, however, the present invention is relevant to multi-tasking systems where the system processor is normally taxed with many functions, including downloading a print map for, and controlling printing or other reproduction operations.
2. Background of Related Art
High-speed digital franking machines, such as those marketed by Ascom Autelca AG, the assignee of the present Letters Patent, are apparatuses that allow a postal customer to both rapidly determine the correct postage for a high volume of mail items, and to affix a postage indicia on the mail item in an automated or semi-automated manner.
Determining the correct postage can involve such steps as weighing the mail, sizing the mail, and determining the mail destination. The general components often include: an initial feeder for individually feeding pieces of mail into the machine, a weighing machine for weighing each piece of mail; a user interface for monitoring and controlling the operation of the machine and for entering data as needed, a postage calculator for calculating the correct postage for each piece of mail; a postage affixer for affixing indicia representing the correct postage on each piece of mail; and a machine discharger for discharging the mail from the machine. The postage may be printed on a sticker and then affixed to the flat (e.g., envelope, postcard, etc.) or parcel, or it may be printed directly onto the mail.
An increased demand for franking machines is partly due to the willingness of various postal authorities to allow private parties to generate their own postage indicia, provided there are secure methods for payment, authentication, fraud prevention and the like. Such a system includes the United States Postal Service's Information-Based Indi- cia Program (IBIP).
Especially where high-speed franking machines are self-contained, the system processor and system bus may handle many tasks that may cause "bottlenecks." Because calculations may be needed to determine the correct postage, and because rapidly moving mail needs postage stickers and regions to be quickly produced, the system buses of prior art high-speed franking machines are often taxed to their limit, causing delays in the franking process or a reduction in the overall franking speed. The same delays and bus bottlenecking observed for high-speed franking machines are often observed for other operations unrelated to franking, where images are output or reproduced will the system
processor must simultaneously perform other tasks which determine the content of the images.
A prior art system 100 that suffers from the aforementioned limitations is generally and schematically illustrated in Figure 1. A system processor (labeled "microproces- sor") 110 controls the system operation, and performs major computational tasks. The system processor 110 is connected to a number of components, including a Random Access Memory (RAM), which may be more appropriately called a Read and Write Memory 130 (via a bus line 120), and to the print head 150 of a printing device (via control lines 140). Figure 1 also shows that the RAM 130 is capable of transferring information to the print head 150 (via bus line 160) under the direction of the system processor 110. Those skilled in the art to which the present invention pertains will appreciate that the lines 120, 140 and 160 can be considered to be part of the system bus. The previous paragraph is reiterated with respect to the potential system bus bottlenecks and possible slowing of the printing process for this type of arrangement. What is therefore lacking in the prior art, but greatly needed, is a system and method for high-speed output or reproduction (e.g., printing) of images, where the images may vary for each reproduction and are determined by the system processor, and where the system bus is not over-taxed by the reproduction function.
It is also desirable to provide such a system with ability to reproduce images or parts of images at lower resolutions to reduce the ink consummation.
SUMMARY OF THE INVENTION
In view of the above-identified problems and limitations of the prior art, the present invention provides a method of converting and reproducing in a sequential manner, a digital image. The method at least includes the steps of calculating the information rep- resenting the digital image by the system processor and storing of this information in a RAM. From this RAM this information is sequentially downloaded to a special purpose digital device, via the system bus coupling. The output of stored information in a user- perceivable form, directly controlling the operation of the output device by the special purpose digital device, and if necessary, contemporaneously with the first step, via the system processor, performing calculations needed to define at least a portion of the digital image.
The present invention also provides a system adapted to convert and reproduce in a sequential manner, a digital image. The system at least includes a system processor, a system bus, a special purpose digital bus coupled to the system processor via the system bus, and an output device directly coupled to the special purpose digital device via a non- system bus coupling, the output device adapted to output digital image information in a user-perceivable form. The system processor is adapted to calculate information representing the digital image and store it into the RAM. The special purpose digital device is adapted to sequentially download the information representing the digital image and control the operation of the output device.
The present invention is described in detail below, with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present-inventive system 200, generally and schematically illustrated in Figure 2, improves significantly over the aforementioned prior art limitations by novelly including an Application Specific Integrated Circuit (ASIC) 280 to handle the direct control of print heads 250. It should be noted that the system 200 is adapted to operate as part of a high-speed digital franking machine, although the invention is not specifically limited to such applications. A system processor 210 is at least connected to the ASIC 280 and a RAM 230 via a system bus 270. Those skilled in the art will appreciate that component
280 need not be limited to being an ASIC, and that other types of special purpose digital circuits will also suffice.
The system processor 210 initiates the printing of an indicia. Then the ASIC 280 begins to transfer digital image information by scan lines out of the RAM 230. During this data download, the ASIC 280 must be the bus master, what it indicates by setting "hold" signal line 294. The processor sets "hold acknowledge" signal line 298 when it goes into the hold state and is no longer the bus master. Thereafter, the ASIC 280 downloads the needed data and the system processor 210 becomes the bus master again. The ASIC 280 also controls the operation of the print heads 250 and transmits image data thereto via a dedicated bus 290. The system processor 210 is used to calculate the information. With this solution, this calculation can be done while printing. It is also possible to calculate parts of the currently printed image. The bus occupation can be reduced by this solution because it takes less time to download the data sequentially into the ASIC than to transfer the data to the print head and because the system processor doesn't have to concern itself with the transfer to the print head.
In franking machines and similar applications, a portion of the images to be printed relies on the calculations of the system processor before the full image (e.g., postage indicia) is complete. This would further delay prior art approaches that require transferring a print map from the system processor to the printing device before printing actu- ally begins. Instead, the present-inventive system begins printing prior to the transfer of a print map, under the control of the ASIC 280, while the system processor performs any calculations necessary for completing the images to be printed (such as calculating the correct postage).
In addition to the advantages obtained by transferring direct printing control from the system processor 210 to the ASIC 280, the present-inventive system 200 also improves upon the prior art by orienting the printing medium (which can be the face of mail, postage stickers, etc.) in a way such that the first portions of the image to traverse the print heads require no calculations before being finalized for printing. Figure 4 shows an example of a flat 400 with postage indicia divided into two regions 430 and 440. In the example shown, the flat 400 moves from left to right past the print heads. Therefore region 430 will be printed (or at least started) prior to region 440, which has IBIP indicia needing calculations before the latter portion of the image can be finalized. Printing can begin before all calculations are performed to save time. The dividing point between the two regions is referred to as the validation point. If the validation point is reached before the calculations are complete, the printing can be aborted without franking. Therefore, there is no loss of money.
Figure 5 illustrates an example of a print head arrangement 150 compatible with the present-inventive system and method. The print head arrangement 150 contains two print heads 152 and 156, each having two rows of staggered print nozzles 154 and 158.
A further aspect of the printing operation of the present-inventive system and method is the ability to control the density of ink for each printed pixel, as illustrated in Figure 5. On the right side of Figure 5 is a group 512 of pixels 514 (with greatly exag- gerated size) with normal print density. That is, two ink drops per pixel area are used. In contrast, the example 502 on the left of Figure 5 illustrates a reduced density of pixels 504 by including one ink drop 506 for each printed pixel. From the examples in Figure 5, it can be seen that at lower density printing, the system has the same resolution than with
normal density, but the ink consummation is reduced. In order to provide equal usage of all nozzles, the two rows are activated alternatively on subsequent imprints.
Variations and modifications of the present invention are possible, given the above description. However, all variations and modifications which are obvious to those skilled in the art to which the present invention pertains are considered to be within the scope of the protection granted by this Letters Patent.
