The key 106 is a hard key, that is, a key formed by hardware. Typical examples thereof include a power switch and a reset switch (both not shown).

Further, the MFP 100 includes a communication IF 108. The communication IF 108 connects the MFP 100 to a communication network (not shown). Since the communication network is assumed to be a wired or wireless LAN (Local Area Network) in the present embodiment, the communication IF 108 is a LAN IF (Local Area Network Interface) or a WLAN IF (Wireless LAN Interface). Of course, a wired LAN and a wireless LAN may exist at the same time, and in this case, the communication IF 108 includes both the LAN IF and the WLAN IF.

The MFP 100 also includes an engine IF 110. A printing engine 111 and a reading engine 112 are connected to the engine IF 110.

FIG. 2 shows an example of the preview display screen 150 displayed on the panel 105. The preview display screen 150 is a screen when the scanning engine 112 displays the image data read from the document in preview.

The preview display screen 150 is formed with a preview display area 150a and a plurality of buttons 150b to 150e. The preview display area 150a is an area for displaying image data to be previewed. The color / monochrome selection button 150b is a button for selecting whether to read the original image in color or monochrome. The 300/600 selection button 150c is a button for selecting whether to read the original image at 300 dpi (dots per inch) or 600 dpi. The continuation button 150d is a button for instructing to continue reading the original image. The stop button 150e is a button for instructing to stop reading the original image.

The document reading process executed by the MFP 100 configured as described above will be described in detail with reference to FIGS. 3 to 5. Hereinafter, in the description of the procedure of each process, the step is referred to as "S".

In the present embodiment, two types of document reading process, document reading process A and document reading process B, are listed. For example, the user may be allowed to select which document reading process to execute, but in addition to this, one may be fixedly adopted for each product of the MFP 100.

FIG. 3 shows the procedure of the document reading process A executed by the MFP 100, particularly the CPU 101. When one or more originals are placed on the ADF 115 and the user presses the scan button (not shown) on the panel 105, the CPU 101 performs the document reading process A when the scan button is detected. Start.

The document reading process A has the following features, that is,
1. 1. When a plurality of originals are transported one by one and the images on each original are read, if the number of originals required for the preview display is read, even before the reading of all the originals is completed. Features to be previewed and
2. 2. A feature that pauses the reading of the original when displaying the preview,
3. 3. When the setting of the scanning engine 112 is changed during the preview display, the image data related to the document scanned before the setting change is processed so as to satisfy the changed setting.
4. When the setting of the scanning engine 112 is changed during the preview display, when the scanning of the document is resumed from the above pause, the feature of restarting the scanning of the image on the document with the changed setting is
Includes.

In FIG. 3, first, the CPU 101 transmits a command to convey one document to the ADF 115 (S1). In response to this, the ADF 115 conveys one document from the installed document to the reading engine 112.

Next, the CPU 101 transmits a reading command for the original image to the reading engine 112 (S2). In response to this, the scanning engine 112 reads the image on the transmitted document, converts it into image data, and then outputs the image data to the engine IF 110. The engine IF 110 temporarily stores the input image data in the RAM 103.

Then, the CPU 101 determines whether or not the reading of the required number of sheets is completed (S3). Here, the "required number of sheets" means the minimum number of documents required for preview display. The image data after reading the original image may be supplied to the printing engine 111 and output to the sheet as described above. In this case, it is possible to select a setting such as 2in1 printing or 4in1 printing in which a plurality of original sheets are reduced and printed on one sheet. When the user selects, for example, a 2in1 printing setting and then presses the scan button, the CPU 101 reads each image from the two originals, reduces the image data related to each image, and previews the image for 2in1 printing. Generate data. Then, the CPU 101 outputs the generated preview image data for 2in1 printing to the panel 105. As a result, a preview screen for 2in1 printing is displayed on the panel 105. Therefore, in this case, the "required number of sheets" is two.

If it is determined in the determination of S3 that the reading of the required number of sheets has not been completed (S3: NO), the CPU 101 returns the process to S1 and continues reading the original, while reading the required number of sheets is completed. If it is determined that the process has been performed (S3: YES), the CPU 101 advances the process to S4.

In S4, the CPU 101 transmits a command to stop the transport of the document to the ADF 115. In response to this, the ADF 115 stops transporting the document and stops reading the document. By the processing of this S4, the above-mentioned feature 2. Is realized.

Next, the CPU 101 transmits an instruction to generate image data for preview display to the image processing circuit 120 based on the image data temporarily stored in the RAM 103 (S5). In response to this, the image processing circuit 120 generates image data for preview display, and outputs the generated image data for preview display to the panel 105. As a result, the preview is displayed in the preview display area 150a in the preview display screen 150. By the processing of this S5, the above-mentioned feature 1. Is realized.

Next, the CPU 101 determines whether or not the setting change is instructed (S6). As described above, the color / monochrome selection button 150b and the 300/600 selection button 150c are displayed on the preview display screen 150. The "setting change is instructed" in S6 means that, in the present embodiment, the setting change is instructed by pressing any of the buttons 150b and 150c.

When it is determined in the determination of S6 that the setting change is instructed (S6: YES), the CPU 101 transmits a command for image processing the read image data to the image processing circuit 120 with the changed setting (S7). In response to this, the image processing circuit 120 performs image processing on the read image data with the changed settings, and stores the image data after the image processing in the temporary RAM 103. Further, the image processing circuit 120 generates image data for preview display based on the image data after image processing, and outputs the image data to the panel 105. As a result, the preview display displayed in the preview display area 150a becomes the preview display after the setting is changed. By the processing of this S7, the above-mentioned feature 3. Is realized.

Specifically, assuming that the settings before the setting change are the color scan setting and the 600 dpi setting, and this is changed to the monochrome scan setting and the 300 dpi setting, the image processing circuit 120 halves the number of pixels of the read image data. The color of each pixel is binarized while thinning out so as to be. On the contrary, if the setting before the setting change is the monochrome scan setting and the 300 dpi setting, and if this is changed to the color scan setting and the 600 dpi setting, the image processing circuit 120 will display the image after the setting change in a short time. Unable to generate data. Therefore, it is necessary to scan the image of the original with the highest setting among the settings that can be changed. The higher setting is a setting that makes image processing more difficult or impossible. Specifically, in the color scan setting and the monochrome scan setting, the color scan setting is higher than the monochrome scan setting. On the other hand, in the 600 dpi setting and the 300 dpi setting, the 600 dpi setting is higher than the 300 dpi setting. Therefore, the highest setting in this case is the color scan setting and the 600 dpi setting.

Next, the CPU 101 changes the setting of the reading engine 112 to the instructed setting (S8), and then proceeds to the process in S9.

On the other hand, when it is determined in the determination of S6 that the setting change has not been instructed (S6: NO), the CPU 101 skips S7 and S8 and proceeds to the process of S9. If "NO" is determined in S6, it means that the user presses the continuation button 150d. In addition to this, a predetermined time may elapse after the preview display.

In S9, the CPU 101 transmits a command to convey one document to the ADF 115 in the same manner as in S1. Here, the transport speed of the document in S1 and the transport speed of the document in S9 may be different. As described above, in S2, the image of the original is read with the highest setting. Therefore, the document transport speed in S1 needs to be a speed at which the image of the document can be read at the highest setting. On the other hand, when a setting change is instructed during the preview display, for example, when the scan resolution is changed from 600 dpi to 300 dpi, the CPU 101 sends a command to the ADF 115 to increase the transport speed of the document to a speed corresponding to the change. To do. Since the setting change instruction is usually an instruction from the highest setting to a lower setting, the document transfer speed in S9 is faster than the document transfer speed in S1 when the setting change instruction is given. Will be.

In the following S10, the CPU 101 transmits a reading command for the original image to the reading engine 112 in the same manner as in the above S2. The scanning engine 112 scans the original image according to the current settings. That is, when the setting is changed by the process of S8, the reading engine 112 reads the original image according to the changed setting. On the other hand, when the processing of S8 is not performed and the setting is not changed, the reading engine 112 reads the document image according to the setting when the document reading process A is started. By the processing of S8 to S10 including S10, the above-mentioned feature 4. Is realized.

Then, the CPU 101 determines whether or not all the pages of the document have been read (S11). In this determination, if it is determined that the reading of all pages of the document has not been completed (S11: NO), the CPU 101 returns the process to S9 and continues reading the document. On the other hand, when it is determined that the reading of all pages of the document is completed (S11: YES), the CPU 101 ends the document reading process A.

4 and 5 show the procedure of the document reading process B executed by the MFP 100, particularly the CPU 101. Similar to the document reading process A, when one or more documents are placed on the ADF 115 and the user presses the scan button (not shown) on the panel 105, the CPU 101 triggers the detection of the press of the scan button. Then, the document reading process B is started. In FIG. 4, the steps for performing the same processing as in FIG. 3 are assigned the same number, and the description thereof will be omitted.

In the document reading process A, the reading of the document image is stopped before the preview display (see S4 in FIG. 3 above), but in the document reading process B, the document image is stopped before or after the preview display. The difference is that it does not stop reading. However, in special cases such as when the RAM 103 has little or no free space for temporarily storing the image data related to the read image, the reading of the original image may be stopped.

In FIG. 4, when the document reading process B starts, the CPU 101 executes the processes S1 to S5. However, the document reading process B does not include the process of S4 included in the document reading process A of FIG. This is because the CPU 101 does not stop reading the original image at the time of preview display.

Next, the CPU 101 transmits a command to convey one document to the ADF 115 in the same manner as in S9 of FIG. 3 (S20), and then reads a command to read the document image in the same manner as in S10 of FIG. It is transmitted to 112 (S22).

Next, the CPU 101 determines whether or not the setting change flag is set (S25). The setting change flag is a flag provided in the RAM 103. The setting change flag is set when the setting change is instructed by the color / monochrome selection button 150b or the 300/600 selection button 150c (see S30 and S43 described later).

When it is determined in the determination of S25 that the setting change flag is in the reset state (S25: NO), the CPU 101 determines whether or not the setting change is instructed (S6). In this determination, when it is determined that the setting change has been instructed (S6: YES), the CPU 101 issues a command to image-process the read image data with the changed setting in the same manner as in S7 of FIG. It is transmitted to 120 (S7'). However, in the processing of S7', the number of originals on which the image data to be image processed is based is different from that of the processing of S7. That is, in the processing of S7, the original that is the basis of the image data to be image-processed is the original that has been read in the number required for the preview display. On the other hand, in the processing of S7', the original that is the basis of the image data to be image-processed is the original that has been read when the processing proceeds to S7'. Then, when the process proceeds to S7', the reading of the number of originals exceeding the number required for the preview display is usually completed.

Next, the CPU 101 changes the setting of the reading engine 112 to the instructed setting (S8), and then sets the setting change flag (S30). After that, the CPU 101 advances the process to S35.

On the other hand, in the determination of S25, when it is determined that the setting change flag is in the set state (S25: YES), or in the determination of S6, it is determined that the setting change has not been instructed (S6: NO). , CPU 101 advances the process to S35.

In S35, the CPU 101 determines whether or not all the pages of the document have been read in the same manner as in S11 of FIG. In this determination, if it is determined that the reading of all pages of the document has not been completed (S35: NO), the CPU 101 returns the process to S20 and continues reading the document. On the other hand, when it is determined that the reading of all pages of the document is completed (S35: YES), the CPU 101 proceeds to S40 of FIG.

As described above, the setting change flag is for causing the CPU 101 to execute the processes of S7', S8, and S30 only once.

In S40 of FIG. 5, the CPU 101 resets the setting change flag.

Next, the CPU 101 determines whether or not the preview is being displayed (S41). This determination is to determine whether or not the preview is still displayed even after the reading of all pages of the manuscript is completed.

If it is determined in the determination of S41 that the preview is not being displayed (S41: NO), the CPU 101 ends the document reading process B. Here, if it is determined that the preview display is not in progress, the user hides the preview display before proceeding to S41, or the user presses the stop button 150e to stop reading the original image. Applicable when instructed. In the former case, that is, when the user hides the preview display, the user approves reading the original image with the settings related to the preview image displayed in the preview. In the latter case, that is, when the user presses the stop button 150e to instruct to stop reading the original image, the user does not approve the reading of the original image with the settings related to the preview image displayed in the preview. Is. In either case, the former case or the latter case, the document reading process B may be terminated. Therefore, in these cases, the CPU 101 ends the document reading process B.

On the other hand, in the determination of S41, when it is determined that the preview is being displayed (S41: YES), the CPU 101 determines whether or not the setting change is instructed (S42) in the same manner as in S6, and sets the settings. If it is determined that the change has been instructed (S42: YES), the setting change flag is set (S43), and then the process proceeds to S44. On the other hand, when it is determined that the setting change has not been instructed (S42: NO), the CPU 101 skips S43 and advances the process to S44.

In S44, the CPU 101 waits until the end of the preview display is instructed (S44: NO), and when the end of the preview display is instructed, the CPU 101 hides the preview display (S45) and then changes the setting. It is determined whether or not the flag is set (S46). In this determination, when it is determined that the setting change flag is in the set state (S46: YES), the CPU 101 performs image processing on a command for image processing the read image data with the changed setting in the same manner as in S7'. It is transmitted to the circuit 120 (S47). However, in the processing of S47, the number of originals on which the image data to be image processed is based is different from that of the processing of S7'. That is, in the processing of S7', the original that is the basis of the image data to be image-processed is the original before the reading of all the pages of the original installed in the ADF 115 is completed. On the other hand, in the processing of S47, the manuscript on which the image data to be image-processed is based is a manuscript in which all pages of the manuscript installed in the ADF 115 have been read.

On the other hand, when it is determined in the determination of S46 that the setting change flag is in the reset state (S46: NO), the CPU 101 ends the document reading process B.

As described above, the MFP 100 of the present embodiment has a reading engine 112 that reads an image from a document and generates image data related to the read image, and a plurality of documents that are read by the reading engine 112, one by one. The ADF 115 conveyed to the reading engine 112, the RAM 103 for storing the image data generated by the reading engine 112, the panel 105 for displaying the preview image of the image data stored in the RAM 103, and when the reading engine 112 reads the document. It includes a panel 105 that selects and accepts settings from a plurality of reading settings, and a CPU 101.

Then, when the image related to the minimum number of originals required for displaying the preview image is read by the scanning engine 112, the CPU 101 does not wait for the reading of all the pages of the plurality of originals to be completed, and the minimum number of originals. A preview image related to the image data related to the minutes of the original is displayed on the panel 105 (S5), and from at least the minimum number of originals, the scanning engine 112 sets the highest number among the plurality of scanning settings to obtain the minimum number of sheets. When the image of the original is read, the image data related to the read image is stored in the RAM 103 (S2), and the setting change for the image data used for displaying the preview image is accepted via the panel 105, the most The image data read by the reading engine 112 with the higher setting and stored in the RAM 103 is image-processed so as to satisfy the changed setting (S7).

As described above, in the MFP 100 of the present embodiment, when the image data is generated while sequentially feeding a plurality of documents by the ADF 115 and the preview display is performed, the preview display can be performed before the scanning of all the documents is completed. ..

By the way, in the present embodiment, the MFP 100 is an example of an "image processing device". The reading engine 112 is an example of a “reading unit”. The ADF115 is an example of an "automatic document feeder". The RAM 103 is an example of a "storage unit". The panel 105 is an example of a “display unit”. Panel 105 is an example of a “reception unit”. The CPU 101 is an example of a “control unit”.

Further, when the preview image is displayed on the panel 105, the CPU 101 stops reading the image from the original by the scanning engine 112 (S4), and when the setting change is accepted via the panel 105, the changed setting is changed. The reading of the image from the original by the scanning engine 112 is restarted by the setting (S8, S9, S10).

Further, when the preview image is displayed on the panel 105, if there is a margin in the free space of the RAM 103, the CPU 101 is set to the highest level by the scanning engine 112 even from the documents after the minimum number of originals. The images of the originals after the minimum number of originals are read, the image data related to the scanned images is stored in the RAM 103 (S22), and the setting change for the image data used for displaying the preview image is accepted via the panel 105. When this is done, all the image data, which is the image data read by the reading engine 112 with the highest setting and stored in the RAM 103, including the image data used for displaying the preview image, is set after the change. Image processing is performed so as to satisfy (S47).

As a result, the reading of the original is continued even after the preview is displayed, so that the reading time can be shortened.

Further, when the CPU 101 receives the change of the setting for the image data used for displaying the preview image via the panel 105, the CPU 101 does not finish reading the images of the plurality of documents by the reading engine 112. , The transport speed of the ADF 115 is increased to the transport speed according to the changed setting to transport the original (S8, S20).

As a result, the transport speed by the ADF 115 is increased, so that the reading time can be further shortened.
