Abstract: An image processing apparatus includes; a mask image generation unit that specifies a region having a luminance value higher than a specific value as a mask region from a target image, generates a mask image by setting the luminance value of a region other than the mask region to zero, a mask expansion processing unit that specifies a portion of a region around the mask region that satisfies a condition and expands the mask region to the peripheral region, a smoothed image generation unit that smooths the entire luminance value of the target image, a corrected image generation unit that specifies a region matching the expanded mask region and sets the luminance value of a region other than the specified region to zero to generate a corrected image, an image synthesize unit that synthesizes the corrected image with the target image to generate a new image.

Abstract: One objective is to provide an image processing device, a control method, and a storage medium capable of suitably presenting information about a position currently being photographed in endoscopic inspection. To achieve the objective, the image processing device 1X includes a panoramic image acquiring unit 43X and a display control unit 46X. The panoramic image acquiring unit 43X acquires a panoramic image Ip, in which a wall surface in a lumen is expanded in a planar shape, based on plural captured images Ic which were acquired by photographing the lumen by a photographing unit provided in an endoscope in a first photographing process. The display control unit 46X displays on the display device 2 photographed position information relating to a photographed position of the lumen in a second photographing process in association with the panoramic image Ip.

Abstract: The image processing device 1X mainly includes a three-dimensional reconstruction means 31X, a matching means 32X, and a display control means 33X. The three-dimensional reconstruction means 31X generates reconstructed data obtained by three-dimensionally reconstructing an examination target, based on endoscopic images of the examination target captured by a photographing unit provided in an endoscope. The matching means 32X performs matching between a three-dimensional model of the examination target and the reconstructed data. The display control means 33X displays information regarding meta data associated with the three-dimensional model, based on a result of the matching.

Abstract: An image processing device 1X includes a three-dimensional reconstruction means 31X, a matching means 32X, and an output control means 33X. The three-dimensional reconstruction means 31X generates reconstruction data Mr acquired by three-dimensionally reconstructing an inspection target on a basis of captured images Ic which a photographing unit provided in an endoscope generates by photographing the inspection target. The matching means 32X performs matching between a standard model “Ms”, which is a standard three-dimensional model of the inspection target, and the reconstruction data Mr. The output control means 33X displays on a display device 2X a photographed area indication image indicating a photographed area of the inspection target on the standard model based on a result of the matching.

Abstract: The endoscopic image acquisition means acquires an endoscopic image. The still image acquisition means acquires a plurality of still images obtained by imaging a lesion included in the endoscopic image. The identity determination means determines an identity of the lesion included in the plurality of still images. The selection means selects a representative image that best represents the lesion, from a plurality of still images determined to correspond to the same lesion, and displays the representative image on the display device.

Abstract: A rectangle creating unit creates a rectangle circumscribing a lesion area in a medical image. A division-number-ratio calculating unit calculates a division-number ratio based on an image aspect ratio of an input image to be input to a device that identifies a lesion and on a rectangle aspect ratio between the length in the vertical direction of and the length in the horizontal direction of the rectangle. A multiplying-factor calculating unit calculates, based on the division-number ratio, a resizing multiplying-factor for each of the vertical direction and the horizontal direction of a rectangular image encircled by the rectangle and including the lesion area. A resizing unit resizes the rectangular image with the resizing multiplying-factor. A dividing unit divides the resized rectangular image into one or more images in such a manner that the size of each divided image matches the size of the input image.
