Abstract

An illumination device (4) that is applied to an imaging unit for imaging an object. The illumination device (4) comprises: an object cover (132) constituted from a member that can transmit light, the object cover (132) being provided so as to guide light from the object to the imaging unit in order to cause the imaging unit to image the object; and light sources (141, 142, 143) provided closer to the imaging unit than the object cover (132), for illuminating the object through the object cover (132). The light sources (141, 142, 143) are provided in a region farther out than an inversion region, in which a region defined by prescribed light beams included in luminous flux closer to the object than the object cover (132) is substantially inverted on the imaging unit side of the object cover (132), the luminous flux impinging on an imaging element (44) via imaging lenses (41a, 41b) from the object side in a state where the imaging lenses (41a, 41b) are focused on the object that contacts the object cover (132).

Abstract

An illumination device (4) for an imager for imaging a target includes an objective cover (132) including a light transmissive member to direct light from the target to the imager to allow the imager to image the target, and at least one light source (141, 142, 143) located nearer the imager than the objective cover (132) to illuminate the target through the objective cover (132). The at least one light source (141, 142, 143) is located outward from an inverted region that is a region formed by substantially inverting, toward the imager and with respect to the objective cover (132), a region defined by predetermined rays of rays nearer the target from the objective cover (132) in a pencil of rays, the pencil of rays entering, through the imaging lens (41a, 41b), the image sensor (44) from the target in contact with the objective cover (132) and in focus with the imaging lens (41a, 41b).

Abstract

An image capture device (30) which photographs a disease part as a subject is provided with: a camera body; a light unit which is disposed on the camera body and provided with a first light source (211a) and a second light source (212a) having mutually different characteristics; and a filter unit (31) which includes at least one independent filter (31A) and is configured to cause the filter (31A) to be positioned on an optical axis of the camera body or withdrawn from the optical axis of the camera body. Pictures are taken serially by having the subject irradiated with light from the first light source (211a) and photographed in a state in which the filter (31A) is positioned on the optical axis of the camera body or withdrawn from the optical axis of the camera body according to a predetermined first mode, and then having the subject irradiated with light from the second light source (212a) and photographed in a state in which the filter (31A) is positioned on the optical axis of the camera body or withdrawn from the optical axis of the camera body according to a predetermined second mode different from the first mode.

Abstract

An identification apparatus includes a first one-vs.-rest identifier, a second one-vs.- rest identifier, and a corrector. The first one-vs.-rest identifier identifies a first class among a plurality of classes. The second one-vs.-rest identifier identifies a second class different from the first class among the plurality of classes. The corrector corrects an identification result provided by the first one-vs.-rest identifier using the identification result provided by the second one-vs.-rest identifier.

Abstract

Provided are a diagnosis assisting device that facilitates a user to grasp a difference of an affected area to perform a highly precise diagnosis assistance, an image processing method in the diagnosis assisting device, and a program. An image processing method in a diagnosis assisting device that diagnoses lesions from a picked-up image comprises performing an image correction on the picked-up image for diagnosis, and subtracting a target pixel value from a pixel value of the picked-up image having undergone the image correction to obtain an input image to an identifier that identifies diseases based on the unknown picked-up image relating to an object to be diagnosed.

Abstract

Provided are a diagnosis assisting device that facilitates a user to grasp a difference of an affected area to perform a highly precise diagnosis assistance, an image processing method in the diagnosis assisting device, and a program. An image processing method in a diagnosis assisting device that diagnoses lesions from a picked-up image includes (A) performing an image processing on the picked-up image. In (A), a peripheral area other than a diagnosis area that has a high probability as diseases in the picked-up image is set to be a measuring area when an image correction is performed.

Abstract

Provided are a diagnosis assisting device, an imaging processing method in the diagnosis assisting device, and a non-transitory storage medium having stored therein a program that facilitate a grasp of a difference in an diseased area to perform a highly precise diagnosis assistance. According to an image processing method in a diagnosis assisting device that diagnoses lesions from a picked-up image, a reference image corresponding to a known first picked-up image relating to lesions is registered in a database, and when a diagnosis assistance is performed by comparing a query image corresponding to an unknown second picked-up image relating to lesions with the reference image in the database, a reference image is created from the reference image by geometric transformation, or a query image is created from the query image by geometric transformation.

Abstract

The invention provides a method of processing an image in a diagnostic apparatus of diagnosing a cutaneous lesion using a cutaneous image, comprising the steps of: (a) obtaining a first detail image made by performing a first component separation filter on a brightness component of the cutaneous image; (b) obtaining a second detail image made by performing a second component separation filter on the brightness component of the cutaneous image, the second component separation filter having properties different from those of the first component separation filter; (c) generating a third detail image based on the first detail image and the second detail image; (d) newly generating a third base image based on the third detail image; and (e) combining the third detail image with the third base image to restore a brightness component and generate a highlighted image.

Abstract

First extracting means 101b-1 of a processing unit 101, based on a brightness component and a color information component of a captured image separated by separating means 101a, extract a candidate region using a first morphology processing based on the brightness component, and second extracting means 101b-2 of the processing unit 101 extract a likelihood of a region from a color space composed of the brightness component and the color information component and perform a second morphology processing to generate a region-extracted image, which is displayed on the display device 120. In this case, the morphology processing including the smoothing filter processing is performed on an extracted candidate region and an extracted likelihood of the region.
