Embodiment approach 1

[0058] figure 1 It is a schematic diagram showing a schematic configuration of the capsule endoscope system according to Embodiment 1 of the present invention. The capsule endoscope system 1 includes: a capsule endoscope 2 that is introduced into the body of the subject 10 to take pictures and wirelessly transmits image data of in-vivo images to a receiving device 3; In-vivo image data wirelessly transmitted by the capsule endoscope 2 ; and an image display device 5 that displays the in-vivo image on a screen based on the in-vivo image data received by the receiving device 3 .

[0059] After the capsule endoscope 2 is swallowed from the mouth of the subject 10, it moves inside the organ of the subject 10 according to the peristaltic movement of the organ, etc. seconds) to sequentially image the inside of the subject 10 to obtain imaging signals, perform predetermined signal processing, and generate in-vivo image data. In addition, every time the capsule endoscope 2 takes an...

Deformed example 1-1

[0113] Next, refer to Figure 10 A first modified example of the image display device according to Embodiment 1 will be described. In the first embodiment described above, the user is made to arbitrarily select the type of image processing to be executed, but the user may be made to select the precision of various image processing. Figure 10 It shows the process selection screen displayed in this modification. In addition, in this modified example 1-1, sampling density information corresponding to the accuracy of various image processing is stored in advance in the storage unit 55 as a parameter.

[0114] if in Figure 10 When a predetermined operation signal (for example, aligning the cursor 131 with one of the icons 101 to 104 and right-clicking the mouse) is input on the processing selection screen 130 shown, the display control unit 59 causes the display unit 60 to display a selection image. A precision selection window 132 for processing precision (for example, three ...

Deformed example 1-2

[0118] Next, refer to Figure 11 with Figure 12 A second modified example of the image display device according to Embodiment 1 will be described. Figure 11 It is a block diagram showing the configuration of an image display device according to Modification 1-2. compared to Figure 4 , this image display device 5 - 2 further includes a trajectory calculation unit 61 in a subsequent stage of the position estimation unit 54 . Other structures are the same as those of the image display device 5 .

[0119] The trajectory calculation unit 61 executes trajectory calculation processing of the capsule endoscope 2 based on estimated position information obtained by the position estimation unit 54 . Specifically, the trajectory calculation unit 61 extracts two temporally adjacent points from the estimated plurality of positions of the capsule endoscope 2, and when the distance between the two points is equal to or less than a predetermined value, the two points are The points are...

Abstract

To provide an image display apparatus, etc., that enables interpretation of radiograms to be started immediately after acquisition of image data captured by a capsule endoscope. The image display apparatus includes an I / F unit 51 for receiving input of information to the image display apparatus; a storage unit 55 for storing in-vivo image data and information related to a position of the capsule endoscope in a subject; an image processing unit 53 for executing image processing on the in-vivo image data; a position estimating unit 54 for estimating a position of the capsule endoscope during image-capturing of the in-vivo image, on the basis of the information related to the position; a processing setting unit 56 for setting a position estimation level of the position estimating processing and a content of the image processing, on the basis of the information received by the input receiving unit; a processing time estimating unit 57 for predicting a processing time required in processing executed by the image processing unit and the position estimating unit, on the basis of the position estimation level and the content of the image processing set by the processing setting unit; and a display unit 60 for displaying the processing time predicted by the processing time estimating unit.

Description

technical field [0001] The present invention relates to an image display device and a capsule endoscope system for displaying in-vivo images obtained by a capsule endoscope introduced into a subject. Background technique [0002] Conventionally, when a capsule endoscope is introduced into the subject to take images of the subject, the following operations are performed: the internal images obtained by the capsule endoscope are viewed through a list of virtual moving images or still images. The image group is observed, and the image whose observation result is abnormal is selected. This operation is called interpretation. [0003] Since the group of in-vivo images taken in one examination is as high as about 60,000 (about 8 hours), the burden on the interpreter is very heavy. Therefore, as an auxiliary function for interpretation, for example, a function has been proposed (for example, refer to Patent Documents 1 to 3): to detect abnormal parts such as hemorrhage and tumor ...
