<Embodiment 1>
FIG. 1 is a diagram showing an external configuration of the information processing system according to the first embodiment of the present invention.

In FIG. 1, an information processing apparatus (host computer: hereinafter abbreviated as PC) 100 and a scanner 104 in which a scanner driver for controlling a scanner 104 that is an image input device is installed are mutually connected via an interface 105. It is connected. The host computer 100 includes a display device 101, a main body 102, and an input device 103. Next, a basic hardware configuration example of the PC 100 that is a host computer will be described with reference to FIG.

  FIG. 2 is a block diagram illustrating a hardware configuration example of the host computer according to the first embodiment of the present invention.

  In FIG. 2, the PC 100 includes a central processing unit (hereinafter referred to as a CPU) 201 that performs data processing and control of various components by performing calculation, determination, and the like according to a control command. A storage device such as a RAM 202 and a ROM 203 storing a control program such as an OS), a scanner driver, and a hard disk (hereinafter referred to as an HDD) 204 is provided.

  In addition, a communication interface 205 (for example, USB, SCSI, etc.) for performing data communication with the scanner 104 and a system bus 209 for connecting various components of the PC 100 to each other are provided.

  Furthermore, a keyboard 206 and a mouse 207, which are equivalent to the input device 103 of FIG. 1 and used as a user interface, and a display device 101 including a CRT and a liquid crystal display are provided. The input device 103 and the display apparatus 101 are connected via an input interface and a graphic controller, respectively.

  Next, the functional configuration of the PC 100 that is the host computer will be described with reference to FIG.

  FIG. 3 is a diagram showing a functional configuration of the host computer according to the first embodiment of the present invention.

  In FIG. 3, the scan application 301 has a function of causing the display device 101 to display image data acquired from the scanner 104 based on the scan instruction of the user interface 307 via the OS and the display driver. The scan application 301 is normally stored on the HDD 204, loaded onto the RAM 202 by the CPU 201, and executed.

  The scanner driver 302 instructs the scanner 104 to execute reading, and enables the image data to be read into the host computer 100. The scanner driver 302 is also a program executed by the CPU 201, and is prepared to enable optimal control according to the function and specifications of the scanner 104.

  In the first embodiment, the scanner 104 has a function (multi-crop function) for reading a plurality of images placed on the document table by a single reading operation (scanning operation). An automatic paper feeder (ADF) for sequentially reading a plurality of documents is provided.

  Next, various components (modules) constituting the scan application 301 will be described.

  It should be noted that all the various components constituting the scan application 301 are realized as software modules.

  When receiving an instruction to execute reading from the user via the user interface 307, the image data acquisition unit 303 causes the scanner 104 to execute reading via the scanner driver 302 based on the instruction, and acquires the read image data. The acquired image data is stored by the storage unit 304. When there are a plurality of images read by the scanner 104, the image data is sequentially acquired one by one and accumulated and stored in the storage unit 304 each time.

  The storage unit 304 has an image number counter for managing the number of stored image data, and increments the counter by 1 each time image data is stored.

  The image number counter counts the number of image data acquired for one or a series of reading processes (jobs) executed by the scan application 301. When another job occurs, The value of the image number counter is reset to zero. Here, the job refers to a reading process from when a user explicitly inputs a reading instruction to the scanning application 301 until a reading end instruction is received.

  The display method determination unit 305 determines whether the image data stored in the storage unit 304 is one image or a plurality of image data. If there is one, the image is displayed on the display area of the display device 101. To determine the first display method for enlarged display. On the other hand, when there are a plurality of images, the second display method is selected in which the plurality of images are displayed as thumbnails on the display area of the display device 101.

  Here, the enlarged display in the first display method and the thumbnail display in the second display method represent the relative difference in display size between the two display methods, and more specifically, the first display method. The enlarged display in means that the image is displayed on the display area in the first display size, and the thumbnail display in the second display method displays each of the plurality of images in the second display size smaller than the first display size. It means to display on the area.

  In addition, the thumbnail display is a reduction in which the image data is reduced so as to fit within a certain very small size while maintaining the aspect ratio of the original image, for example, the display size of 80 × 80 pixels, from the image data acquired from the scanner driver 302. This means that an image (thumbnail image) is created and the thumbnail images are displayed in a list. In particular, in the case of the first embodiment, the display unit 306 appropriately creates a thumbnail image from the image data stored in the storage unit 304.

  The display unit 306 displays the image data stored in the storage unit 304 on the display area of the display device 101 in accordance with the display method determined by the display method determination unit 305. The display of the image data is updated every time image data stored by the storage unit 304 is added. Thus, even when the scanner 104 reads a plurality of images, the image data is displayed one by one in the display area before completing the capture of all the image data, and the user can confirm the read result early. enable.

  Next, details of display processing executed by the scan application 301 according to the first embodiment will be described with reference to FIG.

  FIG. 4 is a flowchart showing display processing executed by the scan application according to the first embodiment of the present invention.

  When the scan application 301 is activated and receives a reading execution instruction from the user via the user interface 307, the image data acquisition unit 303 acquires one piece of image data from the scanner 104 via the scanner driver 302 in step S101. .

  In step S102, the storage unit 304 stores the image data acquired in step S101. If image data that has already been acquired is stored, it is stored in addition to that. At this time, the image number counter is incremented by one.

  Subsequently, in step S103, the display method determination unit 305 refers to the number of image data stored in the storage unit 304 and determines whether the number of image data to be displayed is one. When the number of image data to be displayed is one (YES in step S103), the display method of the image data is determined as the first display method (enlarged display), and the process proceeds to step S104.

  In step S104, the display unit 306 acquires the image data stored in the storage unit 304, resizes the image data to the first display size that is enlarged on the display area, and displays the image data in the display area.

  On the other hand, when there is not one image data to be displayed, that is, when there are a plurality of image data (NO in step S103), the display method of the image data is determined as the second display method (thumbnail display), and the process proceeds to step S105.

  In step S105, the display unit 306 acquires a plurality of image data stored in the storage unit 304, resizes each image data to a display size that is a thumbnail display on the display area, and displays the image data in the display area. .

  Here, a display example in each of the first and second display methods will be described with reference to FIG.

  FIG. 5 is a diagram showing a display example in each display method of the first and second display methods according to the first embodiment of the present invention.

  FIG. 5A is a display example according to the first display method in step S104. Since there is only one image data to be displayed, the image 502a is displayed so as to be maximized in the display area 501. FIG. On the other hand, FIG. 5B is a display example according to the second display method in step S <b> 105, and shows a display example when three pieces of image data are stored in the storage unit 304. In this case, the image 502a displayed in FIG. 5A is a thumbnail whose display size is reduced as shown in FIG. 5B when the second image data is stored in the storage unit 304. A thumbnail is displayed as an image 502b. In addition, the second and subsequent images subsequent to the image 502a are also displayed as thumbnails in the same size as the image 502a.

  Returning to the description of FIG.

  In step S <b> 106, the image data acquisition unit 303 determines whether the acquisition of image data has been completed. If the acquisition of image data is not completed (NO in step S106), the process returns to step S101, the next image data is acquired as appropriate, and the processes in steps S101 to S106 are repeated until the acquisition of the image data is completed. On the other hand, when the acquisition of the image data is finished (YES in step S106), the process is finished.

  With the above processing, the image data display method can be automatically switched from enlarged display to thumbnail display depending on whether the number of image data to be acquired is one or more.

  That is, since the process of FIG. 4 is repeated until one job is completed, when two or more pieces of image data are stored in the storage unit 304, the display method of the image data is the first display method. To the second display method automatically.

  Here, in the first embodiment, the background for switching the display method of the image data according to the number of image data to be displayed is based on the premise that a plurality of images are captured when the image is captured from the scanner 104. Even in such a case, since only one image is actually captured, in such a case, the display form in which one image is displayed in an enlarged display rather than a thumbnail display improves the visibility of the user. This is because it is desirable from the viewpoint of.

  On the other hand, when displaying multiple images, the display form that displays in thumbnail display rather than the enlarged display displays the image data so that the contents of the image data can be confirmed, and confirms the captured image data at once. This is because it is desirable from the viewpoint of improvement of user visibility and work efficiency.

  In the process of FIG. 4, when there are a plurality of image data to be displayed, the display size is thumbnail display of a predetermined size, but the present invention is not limited to this. For example, an appropriate display size may be determined adaptively according to the number of image data to be displayed and the size of the display area, and each image data may be displayed at that display size.

  Hereinafter, display processing executed by the scan application 301 in such a case will be described with reference to FIG.

  FIG. 6 is a flowchart showing an application example of display processing executed by the scan application according to the first embodiment of the present invention.

  In FIG. 6, for example, when the threshold value for determining the display size is set to 4 and the number of image data to be displayed is 4 or less, the optimum value corresponding to the number of images on the display area is set. A case will be described in which the size is determined, and when the size is larger than 4, thumbnail display is used.

  In step S <b> 201, the image data acquisition unit 303 acquires one piece of image data from the scanner 104 via the scanner driver 302.

  In step S202, the storage unit 304 stores the image data acquired in step S201. If image data that has already been acquired is stored, it is stored in addition to that. At this time, the image number counter is incremented by one.

  Subsequently, in step S <b> 203, the display method determination unit 305 refers to the number of image data stored in the storage unit 304 and determines whether the number of image data to be displayed is one. When the number of image data to be displayed is one (YES in step S203), the display method of the image data is determined as the first display method (enlarged display), and the process proceeds to step S206.

  In step S206, the display unit 306 acquires the image data stored in the storage unit 304, resizes the image data to the first display size that is enlarged on the display area, and displays the image data in the display area. This process is the same as step S104 in FIG.

  On the other hand, when the number of display target image data is not one (NO in step S203), in step S204, the display method determination unit 305 determines whether the number of display target image data is two. If there are two pieces of image data to be displayed (YES in step S204), the display method of the two pieces of image data is determined to be the second display method (two-part display), and the process proceeds to step S207.

  In step S207, the display unit 306 acquires two pieces of image data stored in the storage unit 304, resizes each image data to a display size that is a size that divides the display region into two, and displays the image data in the display region. To do.

  On the other hand, when the number of display target image data is not two (NO in step S204), in step S205, the display method determination unit 305 determines whether the number of display target image data is three or four. To do. If the number of image data to be displayed is 3 or 4 (YES in step S205), the display method of the 3 or 4 image data is determined as the third display method (4-division display), and the process proceeds to step S208. move on.

  In step S208, the display unit 306 acquires three or four pieces of image data stored in the storage unit 304, resizes each image data to a display size that is a size that divides the display region into four parts, and displays the image data. Display in the area.

  Here, a display example of the third display method will be described with reference to FIG.

  FIG. 7 is a diagram showing a display example in the third display method according to the first embodiment of the present invention.

  FIG. 7 shows a case where there are three pieces of image data to be displayed, and three images including the image 702 are displayed in a display size that divides the display area 701 into four.

  Returning to the description of FIG.

  In step S205, when the image data to be displayed is not three or four (NO in step S205), the display method determination unit 305 determines the display method of the image data as the fourth display method (thumbnail display), Proceed to step S209.

  In step S209, the display unit 306 acquires a plurality of image data stored in the storage unit 304, resizes each image data to a display size that is a thumbnail display on the display area, and displays the image data in the display area. . This process is the same as step S105 in FIG.

  In step S210, the image data acquisition unit 303 determines whether the acquisition of the image data has ended. If the acquisition of image data is not completed (NO in step S210), the process returns to step S201, the next image data is acquired as appropriate, and the processes in steps S201 to S210 are repeated until the acquisition of the image data is completed. On the other hand, when the acquisition of the image data is finished (YES in step S201), the process is finished.

  With the above processing, the image data can be displayed by automatically switching to the optimum display size in accordance with the number of image data to be displayed within the set threshold range.

  Note that the processing example of FIG. 6 is an example, and various display controls can be realized depending on the application and purpose. For example, the display size may be simply determined according to the number of images. However, in this case, if the number of images becomes enormous, the display size may become too small and may not be suitable for visual recognition. Therefore, as shown in FIG. desirable. Also, if the number of images cannot be displayed in the display area at a time even in the thumbnail display, a screen scroll function such as a scroll bar is configured on the display area so that all image data to be displayed can be displayed. It can be in a viewable state.

  As described above, according to the first embodiment, it is possible to save the user from switching the display method by automatically switching the display method between enlarged display and thumbnail display according to the number of acquired image data. It becomes possible.

  Further, in reading based on the premise of acquiring a plurality of image data, even when only one image data is actually read, the display method is automatically switched according to the number of images to be displayed. In either case, it is possible to execute display of an appropriate size that is always easy to recognize.

<Embodiment 2>
In the first embodiment, the display method of the image data is determined according to the number of image data stored in the storage unit 304. However, depending on the image input device such as the scanner 104, before capturing the actual image data, By executing a simple reading operation (pre-scan function), the number of images to be captured can be acquired in advance.

  Therefore, in the second embodiment, before the image data acquisition unit 303 acquires the image data, the pre-scan function of the scanner 104 is used to acquire the number of images that can be displayed, and the acquired number of images is set. Accordingly, the configuration for determining the display method of the image data will be described.

  Next, the functional configuration of the PC 100 that is the host computer of the second embodiment will be described with reference to FIG.

  FIG. 8 is a diagram showing a functional configuration of the host computer according to the second embodiment of the present invention.

  Note that the scan application 801 in FIG. 8 has a configuration in which an image number acquisition unit 805 is added to the scan application 301 in FIG. 3 of the first embodiment.

  When the image number acquisition unit 805 receives a reading execution instruction from the user via the user interface 808, the image number acquisition unit 805 performs a pre-scan on the scanner 104 via the scanner driver 802 before the image data acquisition unit 803 acquires the image data. The number of read images determined by pre-scanning is acquired. Here, the pre-scan is a function provided in the scanner 104, and performs reading at a high speed at a resolution lower than the resolution for reading an original image.

  The display method determination unit 806 refers to the number of images acquired by the image number acquisition unit 805 and determines the display method in advance before the image data acquisition unit 803 acquires image data. For example, when the number of images is only one, it is determined as the first display method for enlarging display on the display area. On the other hand, when there are a plurality of images, the second display method is switched to the enlarged display when only the first image is displayed, and the thumbnail display when the second image or more is displayed.

  This eliminates the need for the display method determination unit 806 to determine the display method for the image data by referring to the number of image data stored by the storage unit 804 each time image data is acquired, thereby speeding up the processing. Can do.

  The image data acquisition unit 803 and the storage unit 804 correspond to the image data acquisition unit 303 and the storage unit 304 in FIG. 3 of the first embodiment, respectively, and the image data acquisition unit 803 sequentially acquires the image data acquired via the scanner driver 802. The storage unit 804 stores the data.

  The display unit 807 displays the image data stored in the storage unit 804 on the display area of the display device 101 according to the display method determined by the display method determination unit 806. This display is updated each time image data stored by the storage unit 804 is added.

  Next, details of display processing executed by the scan application 801 according to the second embodiment will be described with reference to FIG.

  FIG. 9 is a flowchart showing display processing executed by the scan application according to the second embodiment of the present invention.

  When the scan application 801 is activated and receives an instruction to execute reading from the user via the user interface 808, the image number acquisition unit 805 acquires the number of images from the scanner 104 via the scanner driver 802 in step S301.

  In step S302, the display method determination unit 806 refers to the number of images acquired in step S301 and determines whether the number of images is one. If the number of images is one (YES in step S302), in step S303, the display method determination unit 806 determines the image display method on the display area as the first display method (enlarged display).

  On the other hand, when there are a plurality of images (NO in step S302), in step S304, the display method determining unit 806 displays an enlarged image when only the first image is displayed, and a thumbnail when displaying the second image or more. The second display method to be displayed is determined.

  In step S305, the image data acquisition unit 803 acquires one piece of image data from the scanner 104 via the scanner driver 802.

  In step S306, the storage unit 804 stores the image data acquired in step S305. If image data that has already been acquired is stored, it is stored in addition to that.

  Next, in step S307, the display unit 807 acquires the image data stored in the storage unit 804, and displays the image in the display size for enlarged display or thumbnail display according to the display method determined in step S303 or step S304. Resize the data and display it in the display area.

  In step S308, the image data acquisition unit 303 determines whether the acquisition of the image data has ended. If the acquisition of image data is not completed (NO in step S308), the process returns to step S305, the next image data is acquired as appropriate, and the processes in steps S305 to S308 are repeated until the acquisition of the image data is completed. On the other hand, when the acquisition of the image data is finished (YES in step S308), the process is finished.

  With the above processing, the display method determination unit 806 determines the display method of the acquired image data only once for the first time when the number of images can be determined, instead of determining the display method every time the image data is acquired. It becomes possible to do.

  As described above, according to the second embodiment, in addition to the effects described in the first embodiment, the number of image data to be acquired can be acquired in advance before acquiring the image data. An appropriate display method for the acquired image data can be determined. Therefore, the total throughput can be further improved as compared with the configuration of the first embodiment.

  In the first and second embodiments, the display target image displayed in the display area is the image data acquired from the scanner 104 as the acquisition source. However, the present invention is not limited to this. For example, the present invention can also be applied to a case where an image input device that stores or inputs image data such as a digital camera or a memory card that captures and records image data is used as an image data acquisition source.
