Problems solved by technology

Also, the second shape-dependent filter of JP-A-2002-99896 is used to emphasize a specific shape (shape of microcalcification shadow), but the abnormal part captured in the image of the inside of the lumen does not have the specified shape
Therefore, it is difficult to assume the shape of the abnormal part in advance as described in Japanese Patent Application Laid-Open No. 2002-99896, and then design a structure for remaining through the first shape-dependent filter (such as the above-mentioned curved shape with a large curvature). The optimal shape-dependent filter for distinguishing between folded parts) and abnormal parts
Therefore, even if the two shape-dependent filters are combined, it is difficult to distinguish abnormal parts from groove positions and contour parts

Embodiment approach 1

[0054] First, an image processing device according to Embodiment 1 will be described. figure 1 It is a block diagram illustrating an example of the functional configuration of the image processing device 1 according to the first embodiment. and, figure 2 is a block diagram illustrating a configuration example of the gradient information calculation unit 16 constituting the calculation unit 15, image 3 is a block diagram illustrating an example of the configuration of the closed area generation unit 17, Figure 4 It is a block diagram illustrating a configuration example of the abnormal part detection unit 18 . In addition, in Figure 1 ~ Figure 4 In each of the drawings, solid lines represent data signal lines that connect various parts of the image processing device 1 and transmit data signals such as image signals, and dotted lines represent control signal lines that transmit control signals.

[0055] Such as figure 1 As shown, the image processing device 1 according ...

Embodiment approach 2

[0118] Next, Embodiment 2 will be described. Figure 21 It is a block diagram illustrating the functional configuration of the image processing device 1b according to the second embodiment. In addition, in Figure 21 In , the same reference numerals are assigned to the same configurations as those described in Embodiment 1. FIG. and, Figure 22 It is a block diagram illustrating an example of the configuration of the closed area generation unit 19b constituting the calculation unit 15b. Such as Figure 21 As shown, the image processing device 1b has an external I / F unit 11, an operation unit 12, a display unit 13, a recording unit 14b, a computing unit 15b, and a control unit 20 for controlling the overall operation of the image processing device 1b.

[0119] An image processing program 141b for detecting an abnormal site from a lumen internal image is recorded in the recording unit 14b.

[0120] Furthermore, the calculation unit 15b includes a gradient information calcul...

Abstract

An image processing apparatus includes: a gradient information calculating unit that calculates gradient information of each of pixels, based on pixel values of an intraluminal image; a closed region creating unit that, based on the gradient information, creates a closed region satisfying a condition where the closed region does not include, on the inside thereof, any pixel of which the gradient strength is equal to or higher than a predetermined value, and also, the boundary of the closed region does not curve toward the interior of the closed region, with a curvature equal to or larger than a predetermined value; and an abnormal part detecting unit that detects an abnormal part from the inside of the closed region.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method for processing an image inside a lumen obtained by photographing the inside of a lumen. Background technique [0002] In the past, endoscopes have been widely used as medical observation devices that are introduced into the body of a subject such as a patient to observe the inside of a lumen inside the body. In addition, in recent years, a swallowing endoscope (capsule endoscope) has been developed, which has an imaging device inside a capsule-shaped casing and a device for wirelessly transmitting image data captured by the imaging device to the outside of the body. communication devices, etc. Observation / diagnosis of images of the interior of the lumen (luminal interior image) captured by these medical observation devices requires a lot of experience, and thus a medical diagnosis support function that assists physicians in diagnosis is desired. As an image rec...
