  Another example displayed on the attribute button 250 will be described with reference to FIG. The attribute button 250 shown in FIG. 13 displays the A column 0 to the A column 5. In this case, since the paper size is not so large in the A column 5 and the A column 4, the preview image may be a preview image of the entire image. In this case, when A4 of the attribute button 250 is pressed, the display range setting screen shown in FIG. 14 is displayed. As shown in the display range setting screen, the preview image is a preview image of the entire image. Thus, the attribute can be the size of the image. Further, as shown in the A column No. 5 above, the entire image can be set as a range.

  Next, a screen for setting attributes in image data will be described with reference to FIG. By setting attributes in the image data, a preview image suitable for the image data can be automatically displayed.

  In the image list screen shown in FIG. 15, a user name field 270, an image name field 271, an image attribute field 272, a document size display field 273, a previous button 274, and a next button 275 are displayed. The user name column 270 indicates the owner of the image data. The image name column 271 indicates the name of the image data. The image attribute column 272 indicates the attribute of the image data. In the case of FIG. 15, the image attribute column 272 is not set to indicate that no attribute is set. The document size display field 273 indicates the size of the paper when the image data is printed. The previous button 274 is a button for displaying the previous screen of this screen, and the next button 275 is a button for displaying the next screen of this screen.

  If an unset image attribute field 272 is pressed on this screen, an image attribute setting screen shown in FIG. 16 is displayed.

When “SEIZE” is selected on this screen and the setting button 282 is pressed, the image attribute is set to “SEIZE” as shown in FIG.

  Next, actual processing will be described using a flowchart. FIG. 18 is a flowchart illustrating processing for displaying a preview image. In step S <b> 801, the control unit 110 executes a process for determining whether or not to display an entire image. Details of this processing will be described with reference to a flowchart described later.

  In step S802, control unit 110 determines whether to display the entire image. In this determination, even when the range set by the user is equal to or larger than the entire image, it is determined that the entire image is displayed. If it is determined that the entire screen is displayed, the control unit 110 causes the image management unit 111 to perform image data transfer processing in step S803. In step S804, an image display process is performed, and the image is displayed as a preview image.

  Returning to step S802, if the entire image is not displayed, the control unit 110 determines whether a partial image range is set in step S805. If the range is set, the control unit 110 causes the image management unit 111 to perform image data transfer processing for the set range in step S806, and the image is displayed in step S804.

  If it is determined in step S805 that no range has been set, the control unit 110 displays an image display range setting screen in step S807. In step S808, the control unit 110 acquires information related to the range set by the user. Thereafter, the processes of steps S806 and S804 described above are performed.

  Next, details of the processing in step S801 will be described using the flowchart of FIG. In step S301, the control unit 110 acquires image attributes of image data. In the next step S302, the control unit determines whether a range is set in the image attribute of the image data. Here, the image attribute indicates the type of image data such as drafting or plan. This image attribute can be set in the image data, and a partial image range can be set in advance for each image attribute. Therefore, if an image attribute is set in the image data and a range is set in the image attribute, a preview image can be displayed based on the set range.

  Therefore, in step S302, it is determined whether a range is set for the image attribute. When the range is set, in step S303, the control unit 110 acquires information regarding the range. Next, in step S304, the control unit 110 determines whether the partial image data can be stored in the display memory. When determining that the image can be accommodated, the control unit 110 determines to display the partial image in step S307. If it is determined that it cannot be accommodated, the control unit 110 prompts the user to input a range in step S306.

  If it is determined in step S302 that the range is not set, in step S305, the control unit 110 determines whether the image data can be stored in the display memory. If it is determined that it can be accommodated, in step S309, the control unit 110 determines to display the entire screen. If it is determined that it cannot be accommodated, the control unit 110 prompts the user to input a range in step S308.

  Next, the processing in step S803 in FIG. 18 will be described using the flowchart in FIG. In step S401, the image management unit 111 performs image data compression processing of the entire image data. In step S402, the image management unit 111 performs a transfer process of the compressed image data to the display image storage unit.

  Next, in step S403, the display management unit 114 performs decompression processing on the compressed image data. In step S404, the display management unit 114 DMA-transfers the decompressed image data to the display memory.

  Next, the processing in step S806 in FIG. 18 will be described using the flowchart in FIG. In step S501, the control unit 110 acquires partial image range information. In step S502, the image management unit 111 performs image data compression processing on the partial image data. In step S503, the image management unit 111 performs a process of transferring the compressed image data to the display image storage unit.

  Next, in step S504, the display management unit 114 performs decompression processing on the compressed image data. In step S505, the display management unit 114 DMA-transfers the decompressed image data to the display memory.
