Problems solved by technology

[0007] However, in the image display device described in the above-mentioned Patent Document 1, regardless of whether the inside of the subject is displayed as an image captured by the capsule endoscope, Regardless of the part, each image with high similarity between frames is displayed at high speed or cut out
Therefore, in this conventional image display device, there is a problem in that, in order to shorten the time for observing a series of images in the subject, it is possible to reproduce at high speed a site of interest to the examiner, such as a bleeding site or an internal organ of the test target. (Part of interest) image, or the image of the part of interest is cut off, and it makes it difficult to observe the part of interest that should be observed

Embodiment approach 1

[0044] figure 1 It is a schematic diagram schematically illustrating a configuration example of a capsule endoscope system using the image display device according to Embodiment 1 of the present invention. Such as figure 1 As shown, the capsule endoscope system has: a capsule endoscope 2, which moves along the passing path in the subject 1, and simultaneously takes images of the subject 1; a receiving device 3, which receives the image from the capsule The image data sent by the capsule endoscope 2; the image display device 4, which displays the image in the subject 1 captured by the capsule endoscope 2; exchange of information between them.

[0045] The capsule endoscope 2 has an imaging function for imaging the inside of the subject 1 and a wireless communication function for transmitting image data obtained by imaging the inside of the subject 1 to the receiving device 3 . The capsule endoscope 2 is swallowed by the subject 1, passes through the esophagus in the subjec...

Embodiment approach 2

[0087] Next, Embodiment 2 of the present invention will be described in detail. In the first embodiment described above, images of a predetermined fixed site of interest among a series of images of the subject are displayed at low speed, but in this second embodiment, it is possible to select one of the options for each site in the subject. Expected site of care.

[0088] Figure 7 It is a block diagram schematically showing a configuration example of an image display device according to Embodiment 2 of the present invention. In this image display device 21 , a control unit 22 is provided instead of the control unit 15 of the image display device 4 according to the first embodiment. In the control unit 22, an image extraction unit 22a is provided instead of the image extraction unit 15a in the first embodiment. The other configurations are the same as in the first embodiment, and the same components are given the same reference numerals.

[0089] The control unit 22 perfor...

Embodiment approach 3

[0110] Next, Embodiment 3 of the present invention will be described in detail. In the second embodiment described above, the image of the selected reproducible site among the series of images of the subject is displayed at a low speed at a display frame rate normally set corresponding to any icon in the reproducing operation icon group 100 Images other than the playback location are reproduced. However, in Embodiment 3, the display frame rate of images other than the selected playback location is changed to a high speed.

[0111] Figure 12 It is a block diagram schematically showing a configuration example of an image display device according to Embodiment 3 of the present invention. In this image display device 31 , a control unit 32 is provided instead of the control unit 22 of the image display device 21 according to the second embodiment. In the control unit 32 , an image extraction unit 32 a is provided instead of the image extraction unit 22 a of Embodiment 2, and a ...

Abstract

An image display device with which a time to observe a series of images of the inside of a subject can be reduced without disturbing observation of a desired portion of concern. An image display device for displaying a series of images of the inside of a subject taken on a time-line, the device having an image extraction section (15a) and a frame rate control section (15b), wherein the image extraction section (15a) extracts an image having characteristics of a desired portion in the subject and specifies the extracted image, out of the series of images, as the image of the desired portion, and wherein the frame rate control section (15b) makes a display frame rate of the specified desired portion different from display frame rates of images other than the image of the desired portion.

Description

[0001] technology area [0002] The present invention relates to an image display device that displays a series of images obtained by photographing a desired subject in time sequence. Background technique [0003] In recent years, in the field of endoscopes, swallowing-type endoscopes equipped with imaging functions and wireless communication functions, that is, capsule endoscopes, have appeared, and developments have been made to acquire images captured by the capsule endoscopes. A capsule endoscope system that captures image data of the subject. In this capsule endoscope system, after the capsule endoscope is swallowed from the subject's mouth for observation (examination) until it is naturally discharged from the subject, the capsule endoscope The speculum functions to move within the subject, such as the stomach, small intestine, and other internal organs along with their peristaltic motion, and to take images of the subject at predetermined intervals, for example, at 0.5...
