Abstract: The accuracy of reading a barcode embedded in a printed document is maintained, and at the same time, the amount of toner and the like consumed is reduced. When document information read by scanning is analyzed and the density of the document information is higher than a predetermined threshold vale, that is, when the printed document has a space enough to contain the barcode, the density of the barcode is set such that the density of the barcode is decreased as compared with a case where the density of the document information is lower than the predetermined threshold value. By changing the size of dots and the distance between the dots and thus decreasing the density of the barcode, it is possible to reduce the amount of toner and the like consumed. Then, the set barcode is synthesized with the document information, and the synthesized image is output.

Abstract: The present invention realizes a network printing system capable of accumulating and chasing printed data. Further, by providing a job chasing function on the printer driver side, detailed setting can be done to extract history information of the job chasing function. The detailed setting to extract history information to chase a job can be done only by a specific administrator or user so that the job can be reliably chased, whereas the administrator or user can obtain desired history information. Accordingly, a precise jog chasing system can be established.

Abstract: The inconsistencies of the function included in the print setting resolving process is conducted, and information to indicate that the aforementioned print setting is not been changed is added. Then, based on the added information, it is determined whether the information regarding the print setting is changed or not. Here, in case the data related to print setting is added and also the print setting has not been changed, then the process is not conducted. Moreover, in case the data related to print setting is not added or the print setting has been changed, the process is conducted.

Abstract: The variable length decoder has a memory device including a plurality of lookup tables, and sequentially decodes codewords of variable-length codes using the memory device. The decoded values corresponding to the codewords and control information pieces are stored in the lookup tables. In decoding one codeword, one lookup table is selected from among the plurality of lookup tables. In the decode, one decoded value corresponding to the one codeword, and a control information piece for selecting a next lookup table depending on the decoded value and used for a next decode are produced from the selected lookup table in response to the one codeword in parallel.

Abstract: A mechanism in which whether or not a printing process can be executed in a user's desired format can be recognized by the user before a print output is executed from an application is provided. The application inquires of a printer driver about a restriction value of a printing apparatus in the case of executing the printing process by print setting designated by the user and obtains such a value. Whether or not the printing process can be executed is discriminated on the basis of the obtained print restriction value information and the number of pages of a print document. If it is determined that the printing process cannot be executed, a message showing that it is impossible to execute the printing process is displayed onto a displaying apparatus. If the printing process cannot be executed, the user is allowed to select available print settings.

Abstract: The present invention provides a stream processing apparatus capable of improving the processing performance in the case of continuously processing a plurality of data streams. A control stream, different from a data stream, is prepared, and a program and a parameter are updated in advance in accordance with the control stream. Double buffer areas are prepared in a memory of the stream processing apparatus into which the program and the parameter are stored. The location of the data stream to be input is written in the control stream, and buffers for reading the data stream are multiplexed so as to read in advance the top portion of the data stream to be processed next.

Abstract: A flag indicating whether a decoding process is completed or continued is disposed in each of entries of a decoding process table. A decoded value and a significant bit length are recorded in the entry of a decoding process completion. Information for identifying the decoding process table which is used in a subsequent process, and a bit length that is clipped from a code word which is used when referring to a subsequent table are recorded in the entry of the decoding process continuation. When the decoding process starts, the information for identifying the table to be used and the bit length that is referred to from the code word when referring to the table are designated together with the code word. The decoding process table reference is repeated as the occasion demands. With the above configuration, there is provided a variable length code decoding device.

Abstract: When the trial period for the printer driver of the trial version has elapsed while the license for the printer driver has not been purchased, the normal printing process continues to be enabled, and the density for tint block printing is set to a density at which a latent-image portion appears. Thus, based on the printing results obtained by a printer, the user can observe the same image as the image on which a tint block image is actually printed. As a result, the user understands that unrelated characters “COPY” are superimposed on the original image, and further experiences the effects of the tint block printing function. Further, the user is encouraged to purchase a license for another software product having a tint block printing function.

Abstract: When an error is detected in an error detecting unit in a processor system, the error detecting unit outputs an error signal to an interrupt control unit, and the interrupt control unit outputs a value of an error address register and a control signal to a program counter control unit and rewrites a value of a program counter to a value of an error address register. By this means, the branching process by an error interrupt is realized. In this case, when the error is detected, the process of saving the value of the program counter at the time of error occurrence is not performed, and a specific save register and a control circuit for the recovery to the address at the time of the error occurrence after the end of the error processing are not provided.
