Description

  The present invention relates to an image display device, an image display method, and an image display program for displaying a plurality of images assigned with predetermined frame numbers in a predetermined image display area.

  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. Capsule endoscopes are peristaltic in the body cavity, for example, inside the organs such as stomach and small intestine, after being swallowed from the subject's mouth for observation (examination) and before being spontaneously discharged. And has a function of taking images of the subject at intervals of 0.5 seconds, for example.

  While moving in the body cavity, image data captured by the capsule endoscope is stored in an external memory sequentially transmitted to the outside by wireless communication. By carrying a receiver having a wireless communication function and a memory function, the subject can freely move between swallowing the capsule endoscope and discharging it. After the capsule endoscope is ejected, the doctor or nurse can make a diagnosis by displaying an organ image on a display based on the image data stored in the memory (see Patent Document 1).

  Hereinafter, an image display apparatus according to an embodiment of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments. In the description of the drawings, the same parts are denoted by the same reference numerals. Further, as an image display apparatus according to the present embodiment, an image display apparatus in an in-vivo information acquiring system using a capsule endoscope will be described as an example.

(Embodiment 1)
First, the image display apparatus according to the first embodiment will be described. FIG. 1 is a schematic diagram showing an overall configuration of an in-vivo information acquiring system according to the present embodiment. As shown in FIG. 1, the in-vivo information acquiring system according to the first embodiment is introduced into the body of a receiving device 2 having a receiving function and the subject 1, and captures an in-vivo image to the receiving device 2. A capsule endoscope 3 that performs data transmission is provided. The in-subject information acquisition system also performs image transfer between the image display device 4 that displays an image in the body cavity based on data received by the reception device 2 and the reception device 2 and the image display device 4. A portable recording medium 5. The receiving device 2 includes a receiving jacket 2a worn by the subject 1 and an external device 2b that performs processing of radio signals transmitted and received through the receiving jacket 2a.

  The image display device 4 is for displaying an in-vivo image captured by the capsule endoscope 3 and includes a workstation that displays an image based on data obtained by the portable recording medium 5. The image display device 4 sequentially displays a plurality of still images captured by the capsule endoscope 3 according to frame numbers. Hereinafter, the sequentially displayed images are referred to as pseudo moving images. Note that the image display device 4 may sequentially display still images one by one, or may sequentially display a plurality of still images.

  The portable recording medium 5 is detachable with respect to the external device 2b and the image display device 4, and has a structure capable of outputting or recording information when attached to both. Specifically, the portable recording medium 5 is inserted into the external device 2 b and transmitted from the capsule endoscope 3 while the capsule endoscope 3 is moving in the body cavity of the subject 1. Record the data. Then, after the capsule endoscope 3 is ejected from the subject 1, that is, after the imaging of the inside of the subject 1 is finished, the capsule endoscope 3 is taken out from the external device 2b and inserted into the image display device 4, and the image is displayed. Data recorded by the display device 4 is read out. The data transfer between the external device 2b and the image display device 4 is not limited to a configuration in which the portable recording medium 5 such as a compact flash (registered trademark) memory is used. It is also possible to take a configuration in which the connection is wired.

  Here, the image display device 4 will be described with reference to FIG. FIG. 2 is a block diagram showing a schematic configuration of the image display device 4 shown in FIG. As shown in FIG. 2, the image display device 4 includes an input unit 20, a display unit 30, a storage unit 40, and a control unit 50.

  The input unit 20 is realized by a pointing device such as a keyboard or a mouse, and outputs an operation instruction for the image display device 4 and instruction information for processing performed by the image display device 4 to the control unit 50.

  The display unit 30 is realized by a CRT display, a liquid crystal display, or the like, and displays instruction information or an instruction result of the input unit 20. In addition, the display unit 30 displays the images of the image group Pa as the pseudo moving images in the predetermined pseudo moving image display area in the order of the frame numbers under the control of the display control unit 55. Further, the display unit 30 sequentially displays the graph images generated by the graph image generation unit 54 in a predetermined graph image display region every time the display image is updated in the pseudo moving image display region. The graph image displayed in the graph image display area is a predetermined feature amount corresponding to a predetermined number of front and rear images having an image displayed in the pseudo moving image display area and frame numbers before and after the frame number of the image. Is expressed in correspondence with the frame number.

  The storage unit 40 is realized by, for example, a hard disk device. The storage unit 40 stores various types of information including image information. For example, in the folder F1, an image group Pa captured by the capsule endoscope 3 is stored. Further, information generated by the image processing of the image processing unit 51 is stored in the folder F2. For example, in the folder F2, a table Tb in which the frame number of each image in the image group Pa is associated with a feature amount such as a red level value, or a graph image Gr in which the red level value is graphed in correspondence with each frame number. Is stored.

  The control unit 50 controls each process or operation of the input unit 20, the display unit 30, and the storage unit 40. The control unit 50 includes an image processing unit 51 that processes images and the like included in the image group Pa, and a display control unit 55 that controls display processing in the display unit 30.

  The image processing unit 51 includes a feature amount acquisition unit 52, a feature image detection unit 53, and a graph image generation unit 54. The feature amount acquisition unit 52 acquires a predetermined feature amount for each image in the image group Pa. As shown in Japanese Patent Application No. 2004-120367, the feature amount acquisition unit 52 determines the ratio of the area including the predetermined color information when the area corresponding to the predetermined color information is included in the image information. Acquired feature value. For example, the feature quantity acquisition unit 52 obtains the ratio of red information in the entire image based on the presence and distribution of red information in the color information of the image information, and uses the red level value obtained by leveling this ratio as the feature quantity. Get as.

  The feature image detection unit 53 detects an image having a feature amount based on a predetermined threshold as a feature image based on the feature amount of each image acquired by the feature amount acquisition unit 52. For example, when the red level value of each image acquired by the feature amount acquisition unit 52 exceeds a predetermined threshold, the feature image detection unit 53 determines that there is a high possibility that the image has a bleeding portion. , Detected as a feature image. In this case, as illustrated in FIG. 2, the image processing unit 51 generates a table Ta in which the frame number of each image in the image group Pa is associated with a feature amount such as a red level value. Then, the image processing unit 51 adds a flag indicating that the image is a feature image to the frame number of the image detected as the feature image by the feature image detection unit 53 and outputs the table Ta. For example, in the table Ta, the flag “1” indicates that the image is a feature image, and the flag “0” indicates that the image is not a feature image.

  The graph image generation unit 54 generates a graph image that represents the feature amount of each image in correspondence with the frame number in each image. Each time the display control unit 55 updates an image to be displayed in the pseudo moving image display area, the graph image generating unit 54 sequentially generates a graph image corresponding to the image displayed in the pseudo moving image display area. This graph image associates the feature number corresponding to the image displayed in the pseudo moving image display area with a predetermined number of preceding and following images having frame numbers before and after the frame number of the image, and the frame number. It is a thing. For example, the graph image generation unit 54 refers to the table Ta stored in the folder F2 and generates a graph image Gr that represents the red level value in association with the frame number. The graph image generated by the graph image generation unit 54 is displayed in the pseudo moving image display area by the display control unit 55 rather than the already displayed area corresponding to the already displayed image already displayed in the pseudo moving image display area. An undisplayed area corresponding to a non-displayed image is arranged and displayed on the pseudo moving image display area side. In addition, the graph image generation unit 54 generates a graph image in which the display number of frame numbers in the non-display area is larger than the display quantity of frame numbers in the display area. Then, the graph image generation unit 54 generates a graph image Gr in which a feature amount exceeding a predetermined threshold is emphasized. For example, the graph image generation unit 54 generates a graph image Gr in which the display location of the feature quantity exceeding a predetermined threshold is displayed in a display color different from the display location of the display location of the other feature quantity, The comparison is made to emphasize the frame number of the image that is the feature image. Note that the graph image generation unit 54 may generate a graph image in which a display portion of a feature amount exceeding a predetermined threshold is blinked.

  The display control unit 55 functions as an image display control unit in the claims and also functions as a graph display control unit in the claims. The display control unit 55 causes the display unit 30 to perform pseudo moving image display that displays the image group Pa in the predetermined pseudo moving image display area in the order of frame numbers. The display control unit 55 sequentially updates the graph image generated by the graph image generation unit 54 in the predetermined graph image display area every time the display unit 30 updates the image to be displayed in the pseudo moving image display area. Display. This graph image corresponds to an image displayed in the pseudo moving image display area and a predetermined number of front and rear images having frame numbers before and after the frame number of the image. Then, the display control unit 55 displays an undisplayed area corresponding to an undisplayed image that is not displayed in the image display area rather than an already displayed area corresponding to the already displayed image that is already displayed in the simulated moving image display area. A graph image arranged on the image display area side is displayed. Further, the image control unit 55 displays a graph image in which the parameter axis of the already displayed area is longer than the parameter axis of the undisplayed area.

  Next, with reference to FIG. 3, an image processing procedure performed by the control unit 50 will be described by taking as an example a case where the image group Pa stored in the storage unit 40 is processed. In FIG. 3, first, the image processing unit 51 acquires image information of the image group Pa stored in the folder F1 (step S102). The feature amount acquisition unit 52 acquires the feature amount of each image based on each image information of the acquired image group Pa (step S104). Then, the feature image detection unit 53 detects an image having a feature amount exceeding a predetermined threshold as a feature image based on the feature amount of each image acquired by the feature amount acquisition unit 52 (step S106). The image processing unit 51 associates the frame number of each image with the feature amount of each image, and generates and outputs a table Ta in which a predetermined flag is added to the frame number corresponding to the feature image.

  Thereafter, the display control unit 55 determines whether or not the instruction information for instructing the image display of the pseudo moving image has been received (step S110). When the display control unit 55 determines that the instruction information for instructing the image display of the pseudo moving image is not received (step S110: No), the control unit 50 ends the image processing for the image group Pa. On the other hand, when the display control unit 55 determines that the instruction information for instructing the image display of the pseudo moving image has been received (step S110: Yes), the display control unit 55 initializes the frame number of the image to be displayed (step S112). Then, the display control unit 55 displays the next image to be displayed among the images of the image group Pa in the predetermined pseudo moving image display area of the display unit 30, and the display unit 30 displays the pseudo moving image display area. Then, image display processing for displaying the pseudo moving image is performed (step S114). Here, the graph image generation unit 54 generates a graph image corresponding to the image displayed in the pseudo moving image display area (step S115). Thereafter, the display control unit 55 displays the graph image generated by the graph image generation unit 54 (step S116). Then, the display control unit 55 adds a numerical value corresponding to the number of images displayed in the pseudo moving image display area to the frame number (step S118). Thereafter, the display control unit 55 determines whether or not the instruction information for instructing to end the display of the image is received from the input unit 20 (step S120), and when the instruction information is received (step S120: Yes). Then, the image display on the display unit 30 is terminated. On the other hand, if the display control unit 55 determines that the instruction information for instructing the end of the display of the pseudo moving image is not received from the input unit 20 (step S120: No), the display unit 30 reaches the final image of the image group Pa. It is determined whether it has been displayed (step S122). When the display control unit 55 determines that the display unit 30 has displayed up to the final image of the image group Pa (step S122: Yes), the display control unit 55 ends the pseudo moving image display on the display unit 30. On the other hand, when the display control unit 55 determines that the display unit 30 does not display the final image of the image group Pa (step S122: No), the display control unit 55 proceeds to step S114 and becomes the next display target in the image group Pa. The image is displayed in the pseudo moving image display area, and the display of the pseudo moving image is continued on the display unit 30.

  Next, with reference to FIG. 4, display processing on the display unit 30 of the display control unit 55 will be described. FIG. 4 is a diagram illustrating an example of the display screen of the display unit 30, and a window Wa is displayed on the display screen of the display unit 30. The window Wa is roughly provided with a pseudo moving image display area A1 and a graph image display area A2. The graph image display area A2 is provided below the pseudo moving image display area A1, and a moving image display control button such as the play button 24 is provided below the graph image display area A2.

  In the pseudo moving image display area A1, image groups instructed to display the pseudo moving image are sequentially displayed. For example, as shown in FIG. 4, the case where an image P31 having the frame number “31” is displayed in the pseudo moving image display area A1 will be described as an example. In the graph image display area A2, a graph image Gr31 corresponding to the image P31 displayed in the pseudo moving image display area A1 is displayed. In the graph image Gr31, the vertical axis indicates the frame number, and the horizontal axis indicates the red level value. In the graph image Gr, a straight line ln indicates the red level of the image displayed in the pseudo moving image display area A1. As shown in FIG. 4, when the image P31 is displayed in the pseudo moving image display area A1, the red level value of the image P31 is displayed in “F31” in contact with the straight line ln. The straight line ln is always displayed at the same position regardless of the update of the image in the pseudo moving image display area A1. Thus, by displaying the straight line ln, the user can easily visually recognize which part of the graph image Gr31 corresponds to the image displayed in the pseudo moving image display area A1. The graph image displayed in the graph image display area A2 is updated corresponding to this image every time the image displayed in the pseudo moving image display area A1 is updated. For example, when the image P32 having the frame number “32” is displayed in the pseudo moving image display area A1, the graph image displayed so that “F32” is in contact with the straight line ln corresponding to the image P32. Is displayed. As described above, the graph image displayed in the graph image display area A2 corresponds to the update of the image displayed in the pseudo moving image display area A1, and the moving image is displayed from the pseudo moving image display area A1 side along the arrow Y11. It is updated so that the frame number sequentially moves toward the display control button side.

  In addition, in the graph image Gr31, a non-display area to be displayed in the pseudo moving image display area A1 is displayed on the pseudo moving image display area A1 side rather than an already displayed area already displayed in the pseudo moving image display area A1. ing. In other words, the graph image Gr31 is displayed in the pseudo moving image display area A1 more than the already displayed area Lp corresponding to the images of the frame numbers “F28” to “F30” already displayed in the pseudo moving image display area A1. A non-display area Lf corresponding to images of frame numbers “F32” to “F39” is displayed in the upper part on the side of the pseudo moving image display area A1. Further, in the graph image Gr31, a display corresponding to an image whose red level value exceeds a predetermined threshold is displayed in a display color different from that corresponding to an image whose red level value is equal to or less than the predetermined threshold. It shows that there is. For example, in the frame number “F32” of an image whose red level value is equal to or less than a predetermined threshold, the red level is displayed in the white display Sw, and the frame number “F” is a feature image whose red level value exceeds the predetermined threshold. In “F33”, the red level value is displayed in the red display Sr. As described above, the non-display area Lf indicating the feature amount of the image to be displayed in the future is displayed in advance on the pseudo moving image display area A1 side, so that the user can adjust the viewpoint to the vicinity of the pseudo moving image display area A1. Even if the user has confirmed the above, it is possible to easily visually recognize the tendency of the red level value of the image to be displayed. Further, when there is a red display Sr portion in the non-display area Lf of the graph image Gr31, the user predicts in advance that a feature image is included in the image to be displayed in the pseudo moving image display area A1. It is possible to prevent the feature image displayed in the pseudo moving image display area A1 from being overlooked.

  In the graph image Gr31, the number of frame numbers in the already displayed area Lp is “3” from “F30” to “F28”, whereas the number of frame numbers in the undisplayed area Lf is from “F31”. It is “9” of “F39”. Thus, in the graph image Gr31, the display quantity of the frame number in the non-display area Lf is displayed larger than the display quantity of the frame number in the display area Lp. Thus, since the non-display area Lf is displayed larger than the already-displayed area Lp, the user can easily visually recognize the feature amount of the image to be displayed in the pseudo moving image display area A1.

  In the graph image Gr31, the red level axis Ap in the existing display area Lp is displayed longer than the red level axis Af in the non-display area Lf. As a result, the user can easily confirm the existing display area Lp even when the existing display area Lp corresponding to the image that has already been visually recognized is displayed in an area away from the pseudo moving image display area A1. Therefore, the user can surely compare the feature amount of the image that has already been displayed with the feature of the stored image.

  In the graph image Gr31 illustrated in FIG. 4, the red display Sr is added to the frame number “F33” two frames after the image P31 displayed in the pseudo moving image display area A1, and the user corresponds to the frame number “F33”. It can be confirmed that the image is a feature image. Thus, the user can predict in advance that a feature image will be displayed in the pseudo moving image display area A1 from the difference in display color in the non-display area Lf in the graph image Gr31.

  Therefore, as shown in FIG. 5, when the frame number is “33” and the feature image P33 including the bleeding part B is displayed in the pseudo moving image display area A1, the user displays the feature image in advance. Can be predicted by the graph image displayed in the graph image display area A2, so that the feature image P33 can be reliably recognized without missing.

  As described above, the image display device 4 according to the first embodiment displays a graph image corresponding to the image displayed in the pseudo moving image display area A1 every time the image displayed in the pseudo moving image display area A1 is updated. To do. As a result, the user can predict the display of the feature image in advance by visually recognizing the graph image, and can perform an accurate diagnosis based on the feature image without overlooking the feature image.

  In the first embodiment, the feature amount acquisition unit 52 has been described with respect to the case where the red level value is acquired as the feature amount. The unevenness level value may be acquired as a feature amount. In this case, the feature amount acquisition unit 52 obtains an uneven portion based on the intensity of the shadow in the image, the contour shape, etc., and acquires an uneven level value based on the width of the distribution region of the uneven portion. The feature image detection unit 53 detects an image having a concavo-convex level value exceeding a predetermined threshold among the concavo-convex level values acquired by the feature amount acquisition unit 52 as a feature image. The graph image generation unit 54 generates a graph image in which the unevenness level value acquired by the feature amount acquisition unit 52 is associated with the frame number of each image. For example, like the window Wb shown in FIG. 6, the display control unit 55 corresponds to the image P31 displayed in the pseudo moving image display area A1, and the graph image corresponding to the image P31 generated by the graph image generation unit 54. Gt31 is displayed in the graph image display area A2. Similar to the graph image Gr31, the graph image Gt31 is updated so that the frame number sequentially moves from the pseudo moving image display area A1 side toward the moving image display control button side along the arrow Y12 direction. In the graph image Gt31, a portion where the unevenness level value exceeds a predetermined threshold value indicates the unevenness level value with a red display Str. For example, in the graph image Gt31, the unevenness level values of the frame number “F33” and the frame number “F34” are displayed in red display Srt. Also in this case, the user can predict that the feature image will be displayed in the pseudo moving image display area A1 by visually recognizing the graph image Gt31.

  Furthermore, although the case where a single graph image is displayed in the graph image display area A2 has been described in the first embodiment, a plurality of graph images may be displayed. For example, as in a window Wc shown in FIG. 7, in the graph image display area A2, a graph image Gr31 in which the red level value is associated with the frame number, and a graph image Gt31 in which the unevenness level value is associated with the frame number, May be displayed. Thus, even when a plurality of graph images are displayed, the user can predict that a feature image will be displayed in the pseudo moving image display area A1 by visually recognizing the graph images Gr31 and Gt31. .

(Embodiment 2)
Next, a second embodiment will be described. The capsule endoscope according to the second embodiment includes a PH sensor that measures a PH value around the capsule endoscope when each image of the image group Pa is captured, and PH value information is associated with each image. Send. The image display apparatus according to the second embodiment displays a graph image based on the PH value information transmitted from the capsule endoscope in association with the image captured by the capsule endoscope.

  FIG. 8 is a block diagram of a schematic configuration of the image display apparatus according to the second embodiment. As illustrated in FIG. 8, the image display device 204 according to the second embodiment stores a table Tb in which the PH value information measured by the capsule endoscope 3 is associated with the frame number of each image in the storage unit 40. is doing.
