Description

  The present invention relates to an image display area for displaying an image corresponding to a plurality of image data, an image data corresponding to image data extracted in advance from the plurality of image data, and a predetermined extracted image arranged in a predetermined order. The present invention relates to an image display device including display means for displaying an extracted image display area for displaying a part of an image group.

  In recent years, in the field of endoscopes, swallowable capsule endoscopes have been proposed. This capsule endoscope is provided with an imaging function and a wireless communication function. The capsule endoscope is swallowed from the mouth of the subject for observation (examination) until it is spontaneously discharged until it is spontaneously discharged. It has a function of moving and taking images of the in-subject image at intervals of 0.5 seconds, for example.

  While moving inside the body cavity, image data captured inside the body by the capsule endoscope is sequentially transmitted to the outside by wireless communication and stored in a memory provided in the receiving device. By carrying a receiving device with a wireless communication function and a memory function, the subject can freely move between swallowing the capsule endoscope and discharging it. (For example, refer to Patent Document 1).

  By the way, the in-vivo image captured in this way is taken out from a memory provided in the receiving device, and then displayed on an image display device such as a workstation, and is used for diagnosis by a doctor. As an example of such an image display device, in addition to an image display area in which all input images are sequentially displayed, an extracted image display in which individual extracted images extracted during past browsing are displayed as thumbnails (reduced display), for example. Those with areas are known.

  Here, the number of extracted images is generally large, but the area of the extracted image display area is limited. Therefore, in the conventional image display device, only a part of the extracted images is displayed in the extracted image display area, and the extracted image is displayed by performing scroll processing using the scroll bar arranged at the right end or the lower end of the extracted image display area. Measures such as switching are taken.

Specifically, the control unit 13 has a configuration including a display control unit 16 for controlling the display mode of the display unit 12, and display control of the display unit 12 is performed by the display control unit 16. .

  Next, the display mode of the display unit 12 based on the control of the display control unit 16 will be described. FIG. 3 is a schematic diagram illustrating a display mode of the display unit 12. As shown in FIG. 3, the display unit 12 displays an image display area 12a and an extracted image display area 12b, and relates to various types of image data stored in the captured image database 14 and corresponding to different examinations. A directory display area 19 for displaying the directory structure and a text display area 22 for displaying text information corresponding to the display image are displayed. Each of the display units 12 represents a predetermined function, has icons 20a to 20v formed so that the predetermined function is executed when designated by the instruction unit 9, and has a line shape. A slider bar 27a corresponding to each of all displayable image data positions, an index icon 27b arranged at a position corresponding to the selected image 21 displayed in the image display area 12a in the slider bar 27a, A scroll bar 26a and scroll buttons 26b and 26c for switching the display mode of the extracted image display area 12b are displayed.

  The icons 20 a to 20 v represent various functions, respectively, and are configured such that the display mode and the like change based on the designation of the instruction unit 9. For example, when the icons 20a, 20b, 20e, and 20f are designated by the instruction unit 9, the examination date, patient name, patient information, and option information are displayed in the text display area 22, respectively. Further, the icon 20c is subjected to a predetermined initialization process according to the designation of the instruction unit 9, and the icon 20d is subjected to image data input via the input unit 8 according to the designation of the instruction unit 9, and the icons 20g, 20h, 20i. The search process, the logoff process, and the image display end process are started by the designation of the instruction unit 9, respectively. The icons 20j to 20v are for changing the display mode of the selected image 21 displayed on the image display area 12a. In the auto mode or the mode in which only the bleeding site is extracted by designating the icons 20j and 20k, respectively. A selection image 21 is displayed. The icons 20l to 20q are respectively cued in the rewind direction (for example, in the reverse direction to the imaging order), played back in the rewind direction, frame-forwarded in the rewind direction, and forward ( For example, frame advance in the imaging order), forward reproduction, and forward cueing are performed. Further, the icons 20r and 20s have the playback speed increased or decreased, respectively, with respect to the playback speed (switching speed) when a plurality of image data is sequentially displayed as specified by the instruction unit 9. In addition, the number of selected images 21 displayed in the image display area 12a of the icons 20t to 20v changes to one, two, or four, depending on the designation of the instruction unit 9.

  The slider bar 27a and the index icon 27b are for indicating the positional relationship among the image data corresponding to the selected image 21 displayed in the image display area 12a in all displayable image data. Specifically, all image data that can be displayed is associated with a predetermined position of the slider bar 27a. For example, image data corresponding to the imaging order is associated with the slider bar 27a from the left end toward the right end. The left end of the slider bar 27a is associated with the image captured at the earliest time, and the right end is associated with the image captured at the latest time. The index icon 27b is located on the slider bar 27a and in an area corresponding to image data that is actually displayed on the image display area 12a as the selected image 21. For this reason, the user of the image display apparatus can estimate which part in the subject 1 the selected image 21 being displayed is captured.

  Next, the scroll bar 26a and the scroll buttons 26b and 26c for changing the display mode of the extracted image display area 12b and the extracted image display area 12b will be described. The extracted image display area 12b displays a part of an extracted image group corresponding to a plurality of image data extracted in advance from all displayable image data and arranged in accordance with a predetermined order, for example, before and after the imaging time. It is an area to do. The display mode of the extracted image display area 12b is configured to be switched by designating the scroll bar 26a and the scroll buttons 26b and 26c using the instruction unit 9.

  Specifically, it is as follows. First, in the extracted image display area 12b, there are display areas 24a to 24d which are areas for displaying individual extracted images and are arranged at fixed positions regardless of the presence or absence of an instruction from the instruction unit 9. Thus, the extracted images constituting a part of the extracted image group to be displayed are arranged on the display areas 24a to 24d. For example, in the example of FIG. 3, the extracted image 25-i is arranged on the display area 24a, and the extracted images 25- (i + 1) to 25- (i + 3) are arranged in the display areas 24b to 24d, respectively. The extracted image 25-i indicates an i th extracted image in the extracted image group among a plurality of extracted images.

  Note that each of the extracted images 25-i to 25- (i + 3) is also one of all the images that can be displayed, and thus each has a corresponding position on the slider bar 27a. Therefore, in order to clarify the relationship between each of the extracted images 25-i to 25- (i + 3) and the position on the slider bar 27a, the display unit 12 links the link lines 28-i to 28- between the two. (I + 3) is displayed.

  Next, a change in the display mode when one of the scroll bar 26a and the scroll buttons 26b and 26c is designated by the instruction unit 9 will be described by taking the case where the scroll button 26c is designated as an example. In the present embodiment, when the switching of the display mode is instructed by the instruction unit 9, the display unit 12 displays the display areas 24a to 24d arranged in the extracted image display area 12b without changing the positions. By switching the extracted image to be displayed, it has a function of displaying the entire area of each extracted image to be displayed.

  FIG. 3 is a schematic diagram illustrating a display mode of the display unit 12 after the scroll button 26 c is designated by the instruction unit 9. As shown in FIG. 3, in the extracted image display area 12b after the instruction by the instruction unit 9 is performed, the positions of the display areas 24a to 24d are not changed from those before the instruction, but are displayed in the display areas 24a to 24d, respectively. The extracted image changes. Specifically, the extracted image 25- (i + 1) is newly displayed in the display area 24a where the extracted image 25-i was displayed before the instruction of the instruction unit 9, and the display areas 24b and 24c are respectively displayed. Extracted images 25- (i + 2) and 25- (i + 3) are newly displayed. In the display area 24d, an extracted image 25- (i + 4) that was not displayed before the instruction from the instruction unit 9 is displayed. As described above, in the image display apparatus according to the present embodiment, when the extracted image display area 12b is considered as a whole, a part of the displayed extracted image group is displayed downstream of the image arrangement direction compared to before switching. The part moved by the amount is newly displayed.

  Next, advantages of the image display device according to the present embodiment will be described. First, in the present embodiment, a configuration is adopted in which the display control unit 16 controls so that the positions of the display areas 24a to 24d provided in the extracted image display area 12b are not changed before and after the display mode is switched. As described above, each of the extracted images is displayed in any one of the display areas 24a to 24d. By adopting such a configuration, each extracted image displayed in the extracted image display area 12b Is displayed, and there is an advantage that it is possible to prevent difficulty in grasping the image contents by displaying only a part as in the case of using the conventional scroll processing.

  Further, in the image display device according to the present embodiment, since the positions of the display areas 24a to 24d are respectively fixed, even if the extracted image to be displayed is moved and / or replaced, the extracted image is displayed. The position where is displayed does not change. For this reason, the user of the image display device does not need to switch the line of sight according to the movement of the image display position, and can confirm the content of the extracted image switched while leaving the fixed direction west line. It has the advantage that it can be browsed.

  Furthermore, the image display apparatus according to the present embodiment displays a portion moved by a distance corresponding to one image every time the display mode of the extracted image display area 12b is switched. For this reason, it is possible to easily grasp the positional relationship (before and after the imaging time) between the newly displayed extracted image and the extracted image that has been displayed so far, and can be used easily even for beginners. Have advantages.

(Modification 1)
Next, a first modification of the image display device according to the embodiment will be described. In the modification described below, the basic configuration of the image display apparatus is the same as that shown in FIG. 2, but the display mode of the display unit 12 is different because the control of the display control unit 16 is different from the embodiment. Since it is different from the embodiment, the description about the configuration of the image display device is omitted, and the difference in the display mode of the display unit 12 with respect to the embodiment will be mainly described.

  In the first modification, with respect to the display mode of the extracted image display area 12b, the change in the display mode based on the instruction of the instruction unit 9 is different from that of the embodiment, and specifically, the extraction displayed in the extracted image display area 12b. The portion of the image group is moved by a distance corresponding to the number of images that can be displayed in the extracted image display area 12b by a single instruction.

  FIG. 5 is a schematic diagram showing a change in display mode when the scroll button 26c is designated using the instruction unit 9 in the state shown in FIG. As shown in FIG. 5, in the first modification, the extracted images 25-i to 25- (i + 3) have been displayed in the extracted image display area 12b until one time by a single instruction. 25- (i + 4) to 25- (i + 7) are displayed, and the display mode is changed like a page switching in which all the extracted images are replaced. In other words, the portion of the extracted image group displayed in the extracted image display area 12b is in the downstream direction by a distance corresponding to the number of images (four in the case of FIG. 5) that can be displayed by one instruction from the instruction unit 9. That is, it has moved in the direction in which the imaging time becomes new. FIG. 5 shows changes when the scroll button 26c is designated. For example, when the scroll button 26b is designated, the direction is reverse, that is, in the upstream direction of the array (that is, in the direction in which the imaging time becomes old). Therefore, it moves by a distance corresponding to the number of display images.

  In the first modification, the display mode changes whenever the designation of the scroll button 26c or the like by the instruction unit 9 is performed. For example, the instruction unit is moved in a state where the pointer 23 is moved to the position of the scroll button 26c or the like. In the case where the button 9 is continuously pressed down (ie, dragged) for a predetermined time, the display mode is sequentially switched. However, the display mode of the extracted image display area 12b is not changed during the continuing of such an instruction, and the instruction is completed, that is, when the push of the button or the like is completed, depending on the duration of the instruction in the extracted image group. It is good also as displaying the part which moved only the distance. With such a configuration, not only the burden on the drawing process of the display unit 12 is reduced, but also the advantage of reducing eye fatigue due to constant switching of the display mode as a user of the image display apparatus. Will have.

(Modification 2)

  FIG. 6 is a schematic diagram illustrating a display mode of the display unit 12 in the second modification. As shown in FIG. 6, in the second modification, the display unit 12 displays the first GUI 30a and the second GUI 30b used for display switching by the instruction unit 9, and the position of the extracted image to be displayed in the entire extracted image group. A slider bar 31a and an index icon 31b are displayed.

  The slider bar 31a and the index icon 31b perform the same functions as the slider bar 27a and the index icon 27b for all displayable images. That is, the position on the slider bar 31a is associated with each extracted image, and the index icon 27b is on the slider bar 31a and corresponds to the extracted image that is actually displayed in the extracted image display area 12b. By being located in the region, it is possible to visually grasp which portion on the extracted image group the displayed extracted image corresponds to.

  The first GUI 30a and the second GUI 30b are respectively arranged in the upstream direction (direction in which the imaging time becomes older) and the downstream direction (direction in which the imaging time becomes new) with respect to the arrangement of the extracted images. It is for moving. Specifically, the display mode is changed by designating the first GUI 30a or the second GUI 30b by the instruction unit 9.

  FIG. 7 is a schematic diagram illustrating an example of a change in the display mode of the extracted image display area 12b in the second modification. The example of FIG. 7 shows the case where the second GUI 30b is specified, but as shown in FIG. 7, in the second modification, the display area of the extracted image is continuously fixed according to the duration of the instruction without fixing the display area. And

  Thus, by adopting a configuration in which the display mode is switched by the first GUI 30a and the second GUI 30b without using a scroll bar, it is possible to change the display mode without performing the scroll process, and the burden on the user is reduced. It is possible.

(Modification 3)
Next, Modification 3 of the image display device according to the embodiment will be described. In the third modification, in addition to using the first GUI 30a and the second GUI 30b as in the second modification, the display unit 12 displays the extracted image in a fixed area as in the embodiment. .

  FIG. 8 is a schematic diagram showing a display mode of the display unit 12 in the third modification. As shown in FIG. 8, in the third modification, the slider bar 31a, the index icon 31b, the first GUI 30a, and the second GUI 30b are displayed below the extracted image display area 12b as in the second modification. On the other hand, in the third modification, as shown in FIG. 8, display areas 24a to 24d are formed in the extracted image display area 12b, and the extracted images have a configuration arranged on the display areas 24a to 24d.

  FIG. 9 is a schematic diagram illustrating a display mode changed by designating the second GUI 30b. As shown in FIG. 9, in the third modification, the positions of the display regions 24a to 24d are fixed before and after the switching of the display mode, so that each of the displayed extracted images is similar to the case of the embodiment. The entire area is displayed, and the extracted image group to be displayed moves downstream by a distance corresponding to one image. As described above, it is also effective to display the combination of the configuration of the modification 2 and the configuration of the embodiment, and the image display apparatus according to the modification 3 has the advantages of the embodiment and the modification 2. It is possible to enjoy together.
