[0030]
The image processing controller 108 is connected to the image processing apparatus 1 via the bidirectional interface cable 3 and executes communication control processing with the image processing apparatus 1.
[0031]
<Example of image processing (FIG. 3)>
Next, as an example of image processing, image data generated in the host computer 2 is a display list (hereinafter referred to as “DL”) representing the shape of a drawing object, and the drawing object represented by DL Assume that a rendering process is performed on the image.
[0032]
FIG. 3 is a diagram for explaining a rendering process when a plurality of DLs are generated as raster data. The rendering process is performed in multiple times on DL1 to DL3 (hereinafter, this process is referred to as “re-execution”). Rendering ").
[0033]
The outline of the re-rendering process will be specifically described with reference to FIG. The outline of the process is the same whether the re-rendering process is performed on the host computer 2 side or the image forming apparatus 21 side. However, when the re-rendering is performed on the host computer 2 side, the renderer uses an image processing apparatus by a soft renderer. If done on the 1 side, use a hard renderer.
[0034]
3A to 3C, each display list (DL) has a size that can be processed by the renderer 300. Here, when a single page is composed of three display lists (FIG. 3A), the display list (DL) 1 is first rendered to convert the image, and the image data is converted into the subsequent display list ( DL) 2 as a new display list 301. Subsequently, the combination of DL2 and image 301 is rendered (FIG. 3B), a new image 302 is generated, and used as the background of the display list (DL3) subsequent to DL2 (FIG. 3C). A new display list 303 is generated by rendering the combination of DL3 and image 302. By executing the above re-rendering, the processing of the image data subjected to the predetermined rendering process is completed.
[0035]
When the above processing is performed on the host computer 2 side, the display list 303 is transmitted to the image processing apparatus 1. Since the display list 303 received by the image processing apparatus 1 is data that does not need to be re-rendered by the image forming apparatus 21, it is only necessary to execute normal rendering processing.
[0036]
When this processing is performed on the image processing apparatus 1 side, the display list 303 is further rendered, and the image is sent to the image forming apparatus 21 and output. In this case, the host computer 2 needs to send the display list (DL1 to DL3 (see FIG. 3A)) divided into three to the image processing apparatus 1.
[0037]
<Generation of display list (DL) (FIG. 4)>
Next, the flow of the display list (DL) generation process will be described with reference to FIG. FIG. 4 is a flowchart of display list generation processing. First, in step S401, it is checked whether the display list generated from the page exceeds the limit of the hard renderer. If the display list to be generated does not exceed the limit of the hard renderer (S401-No), since re-rendering processing is not necessary, the process proceeds to step S402, a display list that does not require re-rendering processing is generated, and the processing ends. .
[0038]
On the other hand, if the generated display list exceeds the limit of the hard renderer (S401-Yes), the process proceeds to step S403 to check whether the re-rendering processing capability of the image processing apparatus 1 is notified to the host computer 2 or not. To do. If the re-rendering processing capability is not notified (S403-No), the process proceeds to step S405, and the host computer 2 is set to always perform the re-rendering process. In step S406, the host computer 2 performs the re-rendering process. The display list for performing is generated, and the process ends.
[0039]
When the host computer 2 is notified of the re-rendering processing capability of the image processing apparatus 1 in step S403 (S403-Yes), the process proceeds to step S404, and the number of display lists in the page (for example, FIG. 3A). In this case, it is determined whether DL1 to DL3 indicate three layers.) Exceeds the number of display list layers that can maintain the processing speed of the image processing apparatus 1. In accordance with this determination, if the number of display list hierarchies that can maintain the processing speed is exceeded (S404-Yes), it is determined that re-rendering processing should be performed on the host computer 2, and the process proceeds to step S406. The computer 2 generates a display list for performing the re-rendering process, and ends the process.
[0040]
If it is determined in step S404 that the number of display list hierarchies on the page does not exceed the number of display list hierarchies that can maintain the processing speed of the image forming apparatus 21 (S404-No), the image processing apparatus 1 side again It is determined that the rendering process should be performed, the process proceeds to step S407, a display list for performing the re-rendering process in the image processing apparatus 1 is generated, and the process ends.
[0041]
As described above, according to the present embodiment, it is determined whether the re-development process is performed on the host computer side or the image processing apparatus side according to the processing capability of the image processing apparatus, and an appropriate intermediate language is generated. As a result, it is possible to increase the speed of image processing.
[0042]
Second Embodiment
In the first embodiment, the image processing apparatus 1 executes re-rendering in order to determine whether the re-rendering process is performed on the host computer 2 side or the image processing apparatus 1 (including the image forming apparatus 21) side. The development processing capability of the image data is notified to the host computer 2 side, and generation of the display list is executed by the host computer 2 according to the processing capability and the volume of the display list data to be generated, or the image In the second embodiment, the host computer 2 side predicts whether the re-rendering process should be executed on the host computer 2 side or the printer side. To complete.
[0043]
The flow of display list generation processing in the second embodiment will be described with reference to the flowchart of FIG. FIG. 5 is a flowchart of the display list generation process. First, in step S501, it is checked whether the display list generated from the image data exceeds the limit of the hard renderer. If the display list to be generated does not exceed the limit of the hard renderer (S501-No), since re-rendering processing is not necessary, the process proceeds to step S502, a display list that does not require re-rendering processing is generated, and the processing ends. .
[0044]
When the generated display list exceeds the limit of the hard renderer (S501-Yes), the process proceeds to step S503, and it is checked whether the re-rendering processing capability of the image processing apparatus 1 is predictable. For example, if the host computer 2 can receive from the image processing apparatus 1 information regarding the processing capability of the second CPU (see FIG. 1) that controls the development of the image data and the memory size of the frame memory 15, the processing is repeated. The processing power for rendering can be predicted.
[0045]
If the re-rendering processing capability is unpredictable (S503-No), the process proceeds to step S504, and the host computer 2 is set to always perform the re-rendering process. In step S507, the host computer 2 performs the re-rendering process. The display list for performing is generated, and the process is terminated.
[0046]
On the other hand, if the re-rendering processing capability in the image processing apparatus 1 can be predicted in the process of step S503 (S503-Yes), the process proceeds. On the other hand, it is checked whether or not the processing speed can be maintained when the image processing apparatus 1 performs the re-rendering process. When it is determined that the processing speed cannot be maintained under any of the conditions of S505 and S506 (S505-Yes, S506-Yes), the process proceeds to step S507, and the display list for the host computer 2 to perform the re-rendering process And finishes the process.
[0047]
On the other hand, if it is determined in steps S505 and S506 that the processing speed can be maintained (S505-No, S506-No), the process proceeds to step S508, and the display for the image processing apparatus 1 to perform the re-rendering process. Generate a list and end the process.
[0048]
As described above, according to the present embodiment, it is determined whether the re-development process is performed on the host computer side or the image processing apparatus side according to the processing capability of the image processing apparatus, and an appropriate intermediate language is generated. As a result, it is possible to increase the speed of image processing.
[0049]

[0050]
For example, as shown in FIG. 3, when the compression processing is performed on the image processing apparatus 1 side in order to store the image generated by re-rendering in the frame memory 15 as the background, the memory size is larger than that on the host computer 2 side. Therefore, it is necessary to compress data at a high compression rate.
[0051]
When the re-rendering process is executed on the host computer side, the memory capacity is more than that when the re-development process is executed on the image processing apparatus 1 side. Therefore, the compression rate of the image data can be kept low. Therefore, it is possible to prevent image quality deterioration caused by compressing data at the above-described high compression rate, and to realize high-quality image processing.
[0052]
In the third embodiment, the host computer 2 always performs the re-rendering process when the high-quality mode is selected in the designation of the image forming image quality mode in the image forming apparatus 21 and re-rendering is necessary. This makes it possible to obtain a high-quality output by suppressing the image compression rate to prevent image quality deterioration.
[0053]
In the present embodiment, for example, as illustrated in FIG. 6, when the image quality mode of the image forming apparatus 21 is designated as “high image quality mode” by a setting unit (not illustrated) (S601—Yes), the process is performed in step S602. In step S407, when the host computer 2 performs re-rendering processing and the high-quality mode is not designated (S601-No), the processing proceeds to step S407 and the image processing apparatus 1 performs re-rendering processing. To do.
[0054]
As described above, according to the present embodiment, execution of the re-development process (re-rendering process) is performed on the host computer 2 side or the image processing apparatus according to the designated image mode (whether the image quality is high). When the mode is switched to 1 side and the high image quality mode is designated, it is possible to realize image processing with high image quality by switching the execution of the re-development process to the host computer side.
[0055]
