Embodiment approach 1

[0050] figure 1 It is a schematic diagram showing a schematic configuration of a capsule endoscope system including the image processing apparatus according to Embodiment 1 of the present invention. figure 1 The illustrated capsule endoscope system 1 includes a capsule endoscope 2, which is introduced into a subject 10, generates image data by imaging the subject 10, and superimposes the image data on the subject 10. A receiving device 3 that receives a wireless signal transmitted from the capsule endoscope 2 via a receiving antenna unit 4 worn on the subject 10 ; and an image processing device 5 that acquires an image from the receiving device 3 data and perform prescribed image processing.

[0051] figure 2 It is a block diagram showing a schematic configuration of the capsule endoscope 2 and the receiving device 3 .

[0052] The capsule endoscope 2 is a device in which various components such as an imaging element are built in a capsule-shaped casing of a size that can ...

[0133] Next, the modification 1-1 of Embodiment 1 of this invention is demonstrated.

[0134] In the above-described first embodiment, the imaging time is obtained as the time corresponding to the imaging time of the plurality of feature images extracted from the current image group and the past image group (see steps S13 and S16). However, instead of the imaging time, the number of a series of images obtained by imaging between a certain characteristic image and another characteristic image may be acquired. Here, since the capsule endoscope 2 normally performs imaging at a fixed imaging frame rate, the imaging time and the number of images correspond to each other. In this case, in Figure 4 In step S17 of , it is determined whether the difference between the number of images in a certain section acquired from the current image group and the number of images in the corresponding section acquired from the past image group is greater than or equal to a predetermined reference ...

Deformed example 1-2

[0136] Next, the modification 1-2 of Embodiment 1 of this invention is demonstrated.

[0137] When the image to which the observation caution flag is added is displayed on the observation image D1, the image may be further subjected to predetermined image processing and then displayed. For example, an image analysis process for extracting a predetermined lesion area may be performed on the image to which the observation attention mark is added, and the analysis result may be displayed together with the image when the image is displayed in the main display area d3.

[0138] In addition to this, the observation attention flag can also be used as a parameter of various auxiliary functions when generating and displaying the observation screen.

Abstract

A image processing apparatus includes an image extraction unit that extracts first and second feature images representing first and second feature, respectively from a first image group acquired by sequentially capturing images of inside of a subject, and that further extracts third and fourth feature images representing first and second feature, respectively from a second image group acquired before the first image group, a feature data acquiring unit that acquires first and second feature data characterizing a movement of the capsule endoscope between the first and second feature images and between the third and the fourth feature images, respectively, a comparing unit that compares the first feature data with the second feature data, and a display control unit that performs, with respect to the first image group, display control based on a result of the comparison by the comparing unit.

Description

technical field [0001] The present invention relates to an image processing apparatus and an image processing method for processing an image acquired by a capsule endoscope introduced into a subject and imaging the subject. Background technique [0002] In recent years, in the field of endoscopes, an examination using a capsule endoscope that is introduced into a subject such as a patient and captures an image of the subject has been known. A capsule endoscope is a device that incorporates an imaging function, a wireless communication function, and the like in a capsule-shaped casing having a size that can be introduced into the digestive tract of a subject, and captures image data generated by imaging the subject's body. It is sequentially sent wirelessly to the outside of the subject. A series of image data wirelessly transmitted from the capsule endoscope is temporarily accumulated in a receiving device provided outside the subject, and is transferred (downloaded) from t...
