no. 1 approach

[0043] First, the method of this embodiment will be described. In observation using an endoscope, it is considered that even if a lesion is detected once, the lesion cannot be seen because it is out of the display target range. However, it is not easy to rediscover the disappeared lesion (region of interest). In particular, when the doctor is concentrating on another task or detecting the region of interest for a very short time, the doctor does not pay attention to the detection of the region of interest at first, so it can be said that it can only be expected to accidentally find the region of interest that disappeared.

[0044] Therefore, the present applicant proposes the following method. as described later Figure 14 (A)~ Figure 14 As shown in (C), the region of interest detected in the special light image moves on the image as the imaging unit of the endoscope device moves. Then, if Figure 14 As shown in (C), it is assumed that the display target area is out of t...

no. 2 approach

[0227] refer to Figure 21 An endoscope system including the image processing device according to the second embodiment of the present invention will be described. The endoscope system according to this embodiment includes a light source unit 100 , an insertion unit 200 , an image processing unit 300 , an output unit 400 , and an external interface unit 500 .

[0228] The light source unit 100 includes: a white light source 110 generating white light; a converging lens 120 for converging light emitted from the light source to the light guide fiber 210; and a rotary filter 130 for extracting light of a predetermined wavelength band from the white light.

[0229] like Figure 22 As shown, the rotary filter 130 is composed of two types of filters F1 and F2 having different transmittance characteristics. Regarding the filters F1, F2, for example, Figure 23 As shown, among them, the filter F1 has a transmittance characteristic to transmit light in a wavelength band of 400nm to ...

Abstract

The invention provides an image processing device which can generate guide information according to the determination that whether a target area is disappeared to find out the disappeared target area again to reduce doctors' burden. An image processing device includes a special light image acquisition section (330) that acquires an image Including an object image that includes information in a specific wavelength band as a special light image, an attention area detection section (341) that detects an attention area based on a feature quantity of each pixel of the special light image, a disappearance determination section that determines whether or not the attention area has disappeared from a display target area based on a detection result for the attention area, the display target area being an area displayed on an output section, a guide information generation section (3422) that generates guide information about the attention area that has disappeared based on a determination result of the disappearance determination section, and an output control section (360) that controls output of information Including the guide information generated by the guide information generation section.

Description

technical field [0001] The present invention relates to an image processing device and the like. Background technique [0002] In the past, such a surface-sequential endoscope system has been widely used: using a rotating filter to sequentially irradiate three color lights of R1, G1, and B1 to the tissues in the body cavity, and using images generated from their reflected light images (ordinary light images) ) for diagnosis. Furthermore, an endoscope system has been proposed that sequentially irradiates two types of narrow-band light G2 and B2 different in characteristics from the above-mentioned three-color light to tissues in a body cavity, and performs diagnosis using narrow-band light images generated from their reflected light images. (eg Patent Document 1). [0003] Furthermore, an endoscope system has been proposed that irradiates narrow-band excitation light to tissues in a body cavity, and performs diagnosis using a fluorescence image generated by acquiring autofl...
