BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an image forming apparatus and an image forming method.
2. Description of the Related Art
Some image forming apparatuses perform image processing on image data read by a reading section, such as a scanner. A printing section of the image forming apparatus prints the processed image data. Among image forming apparatuses such as this, there is an image forming apparatus on which an application specific integrated circuit (ASIC) is mounted. The ASIC performs image processing specific to input characteristics of the reading section and output characteristics of the printing section within the image forming apparatus. Among image forming apparatuses such as this, there is an image forming apparatus that actualizes image processing using software, rather than hardware such as the ASIC (refer to, for example, Japanese Patent Application Laid-open No. 2005-122448). In this case as well, the reading section and the printing section of the image forming apparatus are identified and image processing specific to the input characteristics of the reading section and the output characteristics of the printing section is performed.
In recent years, technology has been developed in which an image forming apparatus is configured as follows. A reading device and a printing device that respectively perform image processing operations are connected by a network or the like. In a technology such as this, the reading device and the printing device can each perform various kinds of image processing operations. Therefore, characteristics (input characteristics) of the reading device and characteristics (output characteristics) of the printing device are difficult to identify when this technology is used. Optimal image processing performed based on the input characteristics and the output characteristics is desired.

The operating unit 101 decides an image processing operation to be performed by the image reading device 110 and an image processing operation to be performed by the image printing device 120. The operating unit 101 instructs the image reading device 110 and the image printing device 120 to perform the respective image processing operations. The image reading device 110 reads an image recorded on a paper medium. The image reading device 110 transmits capability information, described-hereafter, to the operating unit 101. The image reading device 110 also performs image processing based on the instruction from the operating unit 101. The image printing device 120 transmits capability information, described hereafter, to the operating unit 101. The image printing device 120 performs image processing on image data processed by the image reading device 110, based on the instruction from the operating unit 101. The image printing device 120 also prints an image onto a paper medium. A device identifier (ID) is for identifying each device and it is associated in advance with the image reading device 110 and the image printing device 120.
Next, a configuration of the image reading device 110 will be described.

The reading section 111 reads the image recorded onto the paper medium. The reading controlling section 112 controls the reading of the image performed by the reading section 111. The job controlling section 113 manages the reading of the image performed by the reading section 11 as a job and controls the job. The image processing section 114 performs image processing on the image read by the reading section 111. The image processing operation program data holding section 115 stores therein an image processing operation program run when the image processing section 114 performs an image processing operation. The image processing operation program data holding section 115 also stores therein parameters and the like used when the program is run. Details of a configuration of the image processing operation program data holding section 115 will be described hereafter. The image data holding section 116 stores therein the image read by the reading section 111 and the image data processed by the image processing section 114. The capability information providing section 118 generates information (capability information [image processing operation capability information]) on an image processing operation that can be performed by the image processing section 114, based on the image processing operation program stored in the image processing operation program data holding section 115. The capability information providing section 118 transmits the generated capability information to the operating unit 101, via the external I/F section 117. The capability information includes a processing operation ID for identifying the image processing operation, a type of image that can be supported as an input for the image processing operation (input image type), a type of image obtained as a result of the image processing operation (output image type), and a type of image editing operation (image editing type). The external I/F section 117 controls communication with the image printing device 120 and the operating unit 101 performed via the network 108.
Next, an internal configuration of the image processing operation program data holding section 115 of the image reading device 110 will be described. FIG. 2 is a block diagram of an example of the internal configuration of the image processing operation program data holding section 115. The image processing section 114 of the image reading device 110 has a function to perform one or more of an image processing operation A, an image processing operation B, and image processing operations C. The image processing operation A is, for example, modulation transfer function (MTF) correction and γ-correction. The image processing operation B is, for example, a smoothing filter. The image processing operations C can be, for example, two kinds of image processing operations. For example, one processing operation is image rotation. The other processing operation is image compositing. The image processing operation A, the image processing operation B, and the image processing operations C are respectively associated with the processing operation ID. In a configuration such as this, the image processing operation program data holding section 115 includes an image processing operation A program holding sub-section 150, an image processing operation B program holding sub-section 151, an image processing operation C program 1 holding sub-section 152, and an image processing operation C program 2 holding sub-section 153. The image processing operation A program holding sub-section 150 stores therein a program run when the image processing operation A is performed.

The image processing operation C data 2 holding sub-section 157 stores therein data such as parameters used when image compositing within the image processing operations C is performed.
The image processing section 114 is required to perform the image processing operation A and the image processing operation B. The image processing section 114 selectively performs the image processing operations C depending, for example, on a request from the user made through an inputting section 103. Therefore, the image processing section 114 is required to use the program stored in the image processing operation A program holding sub-section 150, the program stored in the image processing operation B program holding sub-section 151, the data stored in the image processing operation A data holding sub-section 154, and the data stored in the image processing operation B data holding sub-section 155.

The job controlling section 123 manages the printing performed by the printing section 121 as a job and controls the job. The image processing section 124 performs image processing on the image that is a printing subject. The image processing operation program data holding section 125 stores therein an image processing operation program run when the image processing section 124 performs image processing, parameters used when the program is run, and the like. Details of the image processing operation program data holding section 125 will be described hereafter. The image data holding section 126 stores therein the image that is the printing subject and image data processed by the image processing section 124. The capability information providing section 128 generates information (capability information) on an image processing operation that can be performed by the image processing section 124, based on the image processing operation program stored in the image processing operation program data holding section 125. The capability information providing section 128 transmits the capability information to the operating unit 101, via the external I/F section 127. The external I/F section 127 controls communication with the image reading device 110 and the operating unit 101 performed via the network 108.
Next, an internal configuration of the image processing operation program data holding section 125 of the image printing device 120 will be described. FIG. 3 is a block diagram of an example of the internal configuration of the image processing operation program data holding section 125. The image processing section 124 of the image printing device 120 can perform an image processing operation D and an image processing operation E. The image processing operation D is, for example, a color space conversion from a red-green-blue (RBG) space to a cyan-magenta-yellow-black (CMYK) space. The image processing operation E is, for example, a gradation process. The image processing operation D and the image processing operation E are respectively associated with the processing operation ID. In a configuration such as this, the image processing operation program data holding section 125 includes an image processing operation D program 1 holding sub-section 160, an image processing operation D program 2 holding sub-section 161, an image processing operation E program 1 holding sub-section 162, and an image processing operation E program 2 holding sub-section 163. The image processing operation D program 1 holding sub-section 160 stores therein a program D1 run when the image processing operation D is performed. The image processing operation D program 2 holding sub-section 161 stores therein a program D2 run when the image processing operation D is performed. The image processing operation E program 1 holding sub-section 162 stores therein a program E1 run when the image processing operation E is performed. The image processing operation E program 2 holding sub-section 163 stores therein a program E2 run when the image processing operation E is performed. The image processing operation program data holding section 125 also includes an image processing operation D data 1 holding sub-section 164, an image processing operation D data 2 holding sub-section 165, an image processing operation E data 1 holding sub-section 166, and an image processing operation E data 2 holding sub-section 167.

The image processing operation D data 2 holding sub-section 165 stores therein data such as parameters used when the program D2, run when the image processing operation D is performed, is run. The image processing operation E data 1 holding sub-section 166 stores therein data such as parameters used when the program E1, run when the image processing operation E is performed, is run. The image processing operation E data 2 holding sub-section 167 stores therein data such as parameters used when the program E2, run when the image processing operation E is performed, is run.
The program D1 or the program D2 of the programs run when the image processing operation D is performed can be selectively run. The program E1 or the program E2 of the programs run when the image processing operation E is performed can also be selectively run. An image processing operation arbitrating section 107 of the operating unit 101, described hereafter, decides the program to be selected.
Next, a configuration of the operating unit 101 will be described with reference once again to FIG. 1. The operating unit 101 includes a displaying section 102, the inputting section 103, an application 104, a job requesting section 105, an external I/F section 106, and the image processing operation arbitrating section 107. The displaying section 102 is a liquid crystal display panel or the like. The displaying section 102 displays an operating screen as a user interface. The inputting section 103 is a keyboard or a touch-sensor. The inputting section 103 receives the operation input from the user. The displaying section 102 and the inputting section 103 can be integrally formed into a touch screen. The application 104 is used to actualize a copy processing function. When a copy processing request is received from the inputting section 103, the job requesting section 105 requests that the image reading device 110 perform a reading job required for a copy processing operation. The job requesting section 105 also requests that the image printing device 120 perform a printing job. When the copy processing request is received from the inputting section 103, the image processing operation arbitrating section 107 receives the pieces of capability information from the image reading device 110 and the image printing device 120. The image processing operation arbitrating section 107 decides a combination of image processing operations required for copy processing and a sequence of the image processing operations. The image processing operation arbitrating section 107 transmits the information on the decided combination and sequence to the image reading device 110 and the image printing device 120. The external I/F section 106 controls communication with the image reading device 110 and the image printing device 120 performed via the network 108.
Next, an internal configuration of the image processing operation arbitrating section 107 of the operating unit 101 will be described. FIG. 4 is a block diagram of an example of the internal configuration of the image processing operation arbitrating section 107. The image processing operation arbitrating section 107 includes a capability information acquiring unit 211, a capability table 212, and an image processing information notifying unit 210. The capability information acquiring unit 211 acquires the pieces of capability information from the image reading device 110 and the image printing device 120. The capability table 212 stores therein the pieces of capability information acquired by the capability information acquiring unit 211. For example, as shown in FIG. 4, the capability information from the image reading device 110 and the capability information from the image printing device 120 are stored in a table format. In the capability table 212, the device ID of the image reading device 110 and of the image printing device 120 that identify each device, I/F information related to an interface connecting each device, and the capability information are associated. An IP address is used as the I/F information. As described above, the capability information includes the processing operation ID of the image processing operation, the input image type, the output image type, and the image editing type. Specifically, a device ID ‘scan0’ indicates the device ID associated with the image reading device 110. ‘xxx.yyy.zzz.001’ indicates the IP address assigned to the image reading device 110. Several pieces of capability information of the image reading device 110 are stored. In the pieces of capability information shown in an uppermost row in FIG. 4, in sequence from left to right, ‘IC001’ indicates the processing operation ID associated with the image processing operation A. ‘SRIMG001’ indicates the input image type. ‘SIMG’ indicates the output image type. ‘0’ indicates the image editing type. ‘0’ indicates that a type is not specified.
Based on the pieces of capability information stored in the capability table 212, the image processing information notifying unit 210 decides the combination and the sequence of the image processing operations performed by the image reading device 110 and the image printing device 120. The image processing information notifying unit 210 transmits the information on the combination and the sequence to the image reading device 110 and the image printing device 120.
More specifically, the capability information acquiring unit 211 includes a command generating sub-unit 215 and a response receiving sub-unit 216. The command generating sub-unit 215 generates an extensible markup language (XML)-format acquisition command for acquiring the capability information. The command generating sub-unit 215 transmits acquisition commands to the image reading device 110 and the image printing device 120 by hypertext transfer protocol (http) communication, via the external I/F section 106. The response receiving sub-unit 216 receives the pieces of capability information transmitted from the image reading device 110 and the image printing device 120. The response receiving sub-unit 216 interprets the received capability information and stores the capability information in the capability table 212.
The image processing information notifying unit 210 includes a command generating sub-unit 213 and a deciding sub-unit 214. The deciding sub-unit 214 decides the image processing operation to be performed by the image reading device 110 and the image processing operation to be performed by the image printing device 120 using the pieces of capability information stored in the capability table 212. The command generating sub-unit 213 generates an XML-format image processing setting command (image processing specifying information) as image processing information indicating the combination and the sequence of the image processing operations decided by the deciding sub-unit 214. The command generating sub-unit 213 transmits setting commands to the image reading device 110 and the image printing device 120 by http communication, via the external I/F section 106.
Next, the copy processing operation according to the first embodiment will be described. FIG. 5 is a flowchart of the copy processing operation. When the operating unit 101 of the image forming apparatus 100 receives the operation input from the user requesting copy processing, via the inputting section 103 (Step S1), the image processing operation arbitrating section 107 generates the XML-format acquisition command that requests acquisition of the capability information from the image reading device 110 and the image printing device 120. FIG. 6 is a diagram of an example of the XML-format acquisition command generated by the image processing operation arbitrating section 107. <getCapability></getCapability> indicates that the command is given to request the acquisition of the capability information. <capabilitySort>imageProcess</capabilitySort> indicates that the capability information to be acquired is related to image processing. The image processing operation arbitrating section 107 respectively transmits acquisition commands such as that described above to the image reading device 110 and the image printing device 120 by http communication, via the external I/F section 106 (Step S2).
At the same time, when the image reading device 110 receives the acquisition command transmitted from the operating unit 101 via the external I/F section 117 (Step S3), the capability information providing section 118 generates an XML-format response message including information on the image processing operation that can be performed by the image processing section 114 (capability information), based on the image processing operation program stored in the image processing operation program data holding section 115. FIG. 7 is a diagram of an example of the XML-format response message generated by the capability information providing section 118. <getCapabilityResult> indicates that message a response to the getCapability command in the acquisition command. <xmlnx:sc> indicates an attribute of the image reading device 110 (sc [scanner], herein). A list of pieces of capability information is shown in rows between <capability> and </capability>. In the list, the capability information for each image processing operation are shown in rows between <imageProcess> and </imageProcess>. Each piece of capability information includes the processing operation ID <ID>, the input image type <inputDataType>, the output image type <outputDataType>, and the image editing type <imageEditType>. The processing operation ID <ID> is used to identify each image processing operation. The input image type <inputDataType> indicates the type of image that can be supported as an input for the image processing operation. The output image type <outputDataType> indicates the type of image that can be obtained as a result of image processing operation. The processing operation ID indicates that images that are uniformly the specified image type for image processing have the same characteristics. ‘sc:ImageFX’ indicated as <inputDataType> and <outputDataType> indicates an arbitrary image type. The image can be of any type as long as the image has undergone filter processing. The capability information providing section 118 transmits a response message including the capability information, such as that described above, to the operating unit 101 by http communication, via the external I/F section 117 (Step S5).
Similarly, in the image printing device 120, when the acquisition command transmitted from the operating unit 101 is received via the external I/F section 127 (Step S4), the capability information providing section 128 generates the XML-format response message including the information on the image processing operation that can be performed by the image processing section 124 (capability information), based on the image processing operation program stored in the image processing operation program data holding section 125. FIG. 8 is a diagram of an example of the XML-format response message generated by the capability information providing section 128. <xmlnx:pr> indicates an attribute of the image printing device 120 (pr [printer], herein). The configuration of the response message other than <xmlnx:pr> is similar to that of the response message shown in the FIG. 7. Therefore, explanations thereof will be omitted. The capability information providing section 128 transmits a response message including the capability information, such as that described above, to the operating unit 101 by http communication, via the external I/F section 127 (Step S6).
When the image processing operation arbitrating section 107 of the operating unit 101 receives the response message transmitted from the image reading device 110 and the response message transmitted from the image printing device 120 via the external I/F section 106 (Step S7), the image processing operation arbitrating section 107 stores the capability information included in each response message in the capability table 212 (Step S8). Using the pieces of capability information, the image processing operation arbitrating section 107 decides the combination and the sequence of the image processing operations to be performed by the image reading device 110 and the image printing device 120 (Step S9). Specifically, a combination and sequence of the image processing operations in which the output image type and the input image type match is determined for each image processing operation indicated in respective pieces of capability information. The image processing operation arbitrating section 107 decides the determined combination and sequence to be an optimal image processing flow. The image processing operation arbitrating section 107 generates an XML-format image processing setting command (setting command 1) that is image processing information indicating the image processing operations to be performed by the image reading device 110 and the sequence of the image processing operations. The image processing operation arbitrating section 107 also generates an XML-format image processing command (setting command 2) that is image processing information indicating the image processing operations to be performed by the image printing device 120 and the sequence of the image processing operations. FIG. 9 is a diagram of an example of the setting command 1 generated by the image processing operation arbitrating section 107. <setImageProcess></setImageProcess> indicates that the command is given to set the image processing operations. Regarding the image processing operations to be performed by the image reading device 110, the processing operation ID <ID> of the image processing operation is shown in rows between <imageProcess> and </imageProcess> for each sequence. Specifically, a processing operation ID ‘icollect001’ of the image processing operation A and a processing ID ‘filter002’ of the image processing operation B are indicated as the image processing operations to be performed by the image reading device 110. FIG. 10 is a diagram of an example of the setting command 2 generated by the image processing operation arbitrating section 107. As in FIG. 9, regarding the image processing operations to be performed by the image printing device 120, the processing operation ID <ID> of the image processing operation is shown in rows between <imageProcess> and </imageProcess> for each sequence. Specifically, a processing operation ID ‘csconv002’ is indicated as the image processing operation to be performed by the image printing device 120 when the program D2 is run when the image processing operation D is performed. A processing operation ID ‘htone002’ is indicated as the image processing operation to be performed by the image printing device 120 when the program E2 is run when the image processing operation E is performed. The image processing operation arbitrating section 107 transmits the setting command 1 to the image reading device 110 and the setting command 2 to the image printing device 120 via the external I/F section 106 (Step S10).
When the image reading device 110 receives the setting command 1 transmitted from the operating unit 101 (Step S11), the image processing section 114 performs an image processing operation (the image processing operation A or the image processing operation B, herein) in adherence to the setting command 1 on the image read by the reading section 111. The image reading device 110 stores the processed image data in the image data holding section 116. The image reading device 110 transmits the processed image data to the image printing device 120 via the external I/F section 117 (Step S13). When the image printing device 120 receives the setting command 2 transmitted from the operating unit 101 (Step S12) and receives the processed image data from the image reading device 110 (Step S14), the image processing section 124 performs an image processing operation (the image processing operation using the program D2 as the image processing operation D and the image processing operation using the program E2 as the image processing operation E, herein) in adherence to the setting command 2 on the image data. The image printing device 120 prints the processed image data onto a paper medium (Step S15).

The image printing device 120 can download each program or each piece of data from the server device 230 using the URL.
Next, a configuration of the image processing operation arbitrating section 107 of the operating unit 101 will be described. FIG. 30 is an example of a configuration of the image processing operation arbitrating section 107. According to the fourth embodiment, information stored in the capability table 212 of the image processing operation arbitrating section 107 differs from that according to the first embodiment. In the capability table 212 in FIG. 20, the device ID of the image reading device 110 and the image printing device 120 identifying each device, the I/F information related to the interface connecting each device, and the capability information are associated. The IP address is used as the I/F information. The capability information includes the processing operation ID of the image processing operation, a processor ID identifying the image processing section performing the image processing operation, the input image type, and the output image type. In FIG. 30, each element is arrayed in sequence from left to right for each image processing operation. ‘−1’ indicated as the input image type and the output image type indicates that the image type is not specified.
The image processing operation arbitrating section 107 further includes a URL table 217. As shown in FIG. 30, the URL table 217 includes the processing operation ID of the image processing, the processor ID identifying the image processing section performing the image processing operation, the input image type, the output image type, and the URL indicating respective storing locations of the program run when the image processing operation is performed and parameters used.
The image processing information notifying unit 210 including the image processing operation arbitrating section 107 uses the pieces of capability information stored in the capability table 212 and decides the image processing operation to be performed by the image reading device 110 and the image processing operation to be performed by the image printing device 120. The image processing information notifying unit 210 references the URL table 217 and generates an XML-format image processing setting command including the respective URL of the program run when the image processing operation of a decided combination of image processing operations is performed and the data used when the image processing operation is performed. The image processing information notifying unit 210 transmits the setting commands to the image reading device 110 and the image printing device 120.
The server device 230 includes an external I/F section 231, an image processing operation program data holding section 232, and a responding section 233. The image processing operation program data holding section 232 stores therein programs run when various kinds of image processing operations are performed and data such as parameters used when the image processing operations are performed. The image processing operation program data holding section 232 associates the respective URL of the programs and data with the programs and data and stores therein the associated URL.

When the URL of the program or data is designated by the image reading device 110 or the image printing device 120, the responding section 233 reads the program or data from the image processing operation program data holding section 232 and transmits the read program or data to the image reading device 110 or the image printing device 120, via the external I/F section 231. The external I/F section 231 controls communication with the image reading device 110, the image printing device 120, and the operating unit 101 performed via the network 108.
Next, the copy processing operation according to the fourth embodiment will be described. The copy processing operation according to the fourth embodiment is similar to those shown in FIG. 5 so that a diagram thereof is omitted. Procedures differing from those according to the first embodiment will be described in detail.
At Step S5, the capability information providing section 118 of the image reading device 110 generates the response message. However, the capability information included in the response message differs from that according to the first embodiment. FIG. 31 is a diagram of an example of the response message generated by the capability information providing section 118. Each piece of capability information includes the processing operation ID <ID> for identifying the image processing operation, the input image type <inputDataType>, the processor ID <processorID> identifying the image processing section 114 of the image reading device 110, and the output image type <outputDataType>.
Similarly, the capability information included in the response message generated by the capability information providing section 128 of the image printing device 120 at Step S6 differs from that according to the first embodiment. FIG. 32 is a diagram of an example of the response message generated by the capability information providing section 128. Each piece of capability information includes the processing operation ID <ID> for identifying the image processing operation, the input image type <inputDataType>, the processor ID <processorID> identifying the image processing section 124 of the image printing device 120, and the output image type <outputDataType>.
At Step S7, when the response message transmitted from the image reading device 110 and the response message transmitted from the image printing device 120 are received via the external I/F section 106, the image processing operation arbitrating section 107 of the operating unit 101 stores the capability information included in each response message in the capability table 212 (Step S8). Using the pieces of capability information, the image processing operation arbitrating section 107 decides the combination and the sequence of the image processing operations to be performed by the image reading device 110 and the image processing operations to be performed by the image printing device 120 (Step S9). Specifically, the combination and the sequence of the image processing operations in which the output image type and the input image type match is determined for each image processing operation indicated in respective pieces of capability information. The image processing operation arbitrating section 107 decides the determined combination and sequence to be an optimal image processing flow. The image processing operation arbitrating section 107 generates an XML-format image processing setting command (setting command 8) including the URL of the program run when the image processing operation within the combination of image processing operations to be performed by the image reading device 110 is performed and the data used when the image processing operation is performed, with reference to the URL table 217. The image processing operation arbitrating section 107 also generates an XML-format image processing setting command (setting command 9) including the URL of the program run when the image processing operation to be performed by the image printing device 120 is performed and the data used when the image processing operation is performed (Step S10). FIG. 33 is a diagram of an example of the setting command 8 generated by the image processing operation arbitrating section 107. Regarding the image processing operations to be performed by the image reading device 110, the processing operation ID <ID> of the image processing operation is shown in rows between <imageProcess> and </imageProcess> for each sequence. Specifically, a processing operation ID ‘icollect’ of the image processing operation A and a processing ID ‘filter002’ of the image processing operation B are indicated as the image processing operations to be performed by the image reading device 110. The storing locations of the programs run when each image processing operation is performed are respectively indicated in a <programUrl> row. The storing locations of the pieces of data used when the programs are run are respectively indicated in <paramUrl>. FIG. 34 is a diagram of an example of the setting command 9 generated by the image processing operation arbitrating section 107. As in FIG. 33, regarding the image processing operations to be performed by the image printing device 120, the processing operation ID <ID> of the image processing operation is shown in rows between <imageProcess> and </imageProcess> for each sequence. Specifically, a processing operation ID ‘csconv’ of the image processing operation D and a processing ID ‘htone’ of the image processing operation E are indicated as the image processing operations to be performed by the image printing device 120. The storing locations of the programs run when each image processing operation is performed are respectively indicated in a <programUrl> row. The storing locations of the pieces of data used when the programs are run are respectively indicated in <paramUrl>. The image processing operation arbitrating section 107 transmits the setting command 8 to the image reading device 110 and the setting command 9 to the image printing device 120, via the external I/F section 106.
When the image reading device 110 receives the setting command 8 transmitted from the operating unit 101 (Step S11), at Step S13, the image reading device 110 processes the program run when each image processing operation (the image processing operation A and the image processing operation B, herein) specified in the setting command 8 is performed and the data used when the program is run as follows. The image reading device 110 compares each URL specified in the setting command 8 for each program run when the image processing operation A and the image processing operation B are performed and each piece of data used when the programs are run with each URL associated with each program respectively stored in the image processing operation A program holding sub-section 150 and the image processing operation B program holding sub-section 151 and each piece of data respectively stored in the image processing operation A data holding sub-section 154 and the image processing operation B data holding sub-section 155 of the image processing operation program data holding section 115. When a program or a piece of data of which the URL specified in the setting command 8 and the associated URL in the image processing operation program data holding section 115 do not match is present, the image reading device 110 judges that the program or the piece of data is required to be downloaded. The image reading device 110 uses the URL specified in the setting command 8 and accesses the server device 230. The image reading device 110 downloads the program or the piece of data and stores the program or data in the corresponding holding sub-section within the image processing operation program data holding section 115. When the URL specified in the setting command 8 and the associated URL in the image processing operation program data holding section 115 of the program or the piece of data match, the image reading device 110 judges that downloading is not necessary. The image processing section 114 performs the image processing operation A and the image processing operation B on the image read by the reading section 111, using the program and data stored in the image processing operation program data holding section 115. The image data holding section 116 stores the processed image data. The image reading device 110 transmits the processed image data to the image printing device 120, via the external I/F section 117.
When the image processing operations C are specified in the setting command 8 transmitted from the operating unit 101, the image reading device 110 compares each URL specified in the setting command 8 for the programs run when the image processing operations C are performed and each URL associated with the programs stored in the image processing operations C program 1 holding sub-section 152 and image processing operations C program 2 holding sub-section 153. When the URL specified in the setting command 8 and the URL associated with the program stored in either one of the holding sub-sections match, the image processing operation C is performed using the program. When the URL specified in the setting command 8 for the program run when the image processing operation C is performed does not match the URL associated with the program in either holding sub-section, the image reading device 110 downloads the program using the URL specified in the setting command 8. The same applies to the data used when the image processing operation C is performed. When each URL specified in the setting command 8 and each URL associated with the pieces of data stored in the image processing operations C data 1 holding sub-section 156 and image processing operations C data 2 holding sub-section 157 do not match, the data is downloaded.
At the same time, when the image printing device 120 receives the setting command 9 transmitted from the operating unit 101 (Step S12) and receives the image data transmitted from the image reading device 110 (Step S14), at Step S15, the image printing device 120 processes the program run when each image processing operation (the image processing operation D and the image processing operation E, herein) specified in the setting command 9 is performed and the data used when the program is run as follows. As does the image reading device 110, the image printing device 120 compares each URL specified in the setting command 9 for each program run when the image processing operation D and the image processing operation E are performed and each piece of data used when the programs are run with each URL associated with each program and each piece of data respectively stored in the image processing operation D program 1 holding sub-section 160, the image processing operation D program 2 holding sub-section 161, the image processing operation E program 1 holding sub-section 162, the image processing operation E program 2 holding sub-section 163, the image processing operation D data 1 holding sub-section 164, the image processing operation D data 2 holding sub-section 165, the image processing operation E data 1 holding sub-section 166, and the image processing operation E data 2 holding sub-section 167. When a program or a piece of data of which the URL specified in the setting command 9 and the associated URL in the holding sub-sections do not match is present, the image printing device 120 uses the URL specified in the setting command 9 and accesses the server device 230. The image reading device 110 downloads the program or the piece of data and stores the program or data in the corresponding holding sub-section within the image processing operation program data holding section 125. The image processing section 124 performs the image processing operation D and the image processing operation E on the image data transmitted from the image reading device 110, using the program and data stored in the image processing operation program data holding section 125. The image printing device 120 prints the processed image onto a paper medium.
According to a configuration such as that described above, the image reading device 110 and the image printing device 120 can download the program and data used to perform image processing from the server device 230 as required. Therefore, the image processing operation can be performed using a more suitable program. An optical image processing flow adhering to the input characteristics and the output characteristics can be actualized.
In an image forming apparatus according to an aspect of the present invention including an image reading unit and an image printing unit that respectively include an image processing section, an optical image processing flow adhering to the characteristics of the image reading unit and the characteristics of the image printing unit can be actualized by an image processing operation that can be performed by the image reading unit and an image processing operation that can be performed by the image printing unit being decided using image processing operation capability information.
In the above aspect, optimal program and data for performing the image processing operation can be used by at least one of a program used to perform the image processing operation or a piece of data used to run the program being acquired from a server device.
Moreover, even when the image forming apparatus is configured with various combinations of a reading section, a printing section, and the image processing section, a combination of image processing operations to be performed by various image processing sections and a sequence of the image processing operations can be decided using the image processing operation capability information on the image processing operations that can be performed by the various image processing sections. The optimal image processing flow can be actualized.
Furthermore, image processing operation specifying information including identifying information identifying at least one of the program run to perform the image processing operation or the piece of data used to run the program is transmitted to the image reading unit and the image printing unit. As a result, the image reading unit and the image printing unit can acquire the optimal program for performing the image processing operation or the piece of data used when the program is run from the server device, using the identifying information. Therefore, for example, latest programs and pieces of data supporting upgrades and the like can be acquired. Optimal processing can be performed for each image processing operation. For example, an image forming apparatus including a combination of an image reading unit and an image printing unit from different manufacturers can be flexibly supported.
Moreover, a controlling section transmits the image processing operation specifying information to the image reading unit and the image printing unit. The image processing operation specifying-information includes input and output specifying information specifying an input image type of an image that can be supported as an input for the image processing operation and an output image type of an image obtained as a result of the image processing operation. As a result, the image reading unit and the image printing unit can perform the image processing operation in adherence to the input image type and the output image type of the image processing operation. Therefore, for example, the latest programs and pieces of data supporting upgrades and the like can be acquired. Optimal processing can be performed for each image processing operation. For example, an image forming apparatus including a combination of an image reading unit and an image printing unit from different manufacturers can be flexibly supported.
Although the invention has been described with respect to specific embodiments for a complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art that fairly fall within the basic teaching herein set forth.
