Abstract: Provided are an image processing device and a method for operating the same, and an endoscope processor device and a method for operating the same that accurately measure the blood vessel depth of blood vessels in an observation target. A data set including a plurality of items of measurement data in which blood vessel index values, such as blood vessel contrast and a plurality of blood vessel index value variation factors including the blood vessel depth are associated with each other is stored in a data set storage unit 97. A specific blood vessel index value variation factor other than the blood vessel depth is measured. The data set is narrowed to a sub-data set having the specific blood vessel index value variation factor. A blood vessel depth corresponding to a blood vessel index value calculated by the blood vessel index value calculation unit is found from the sub-data set.

Abstract: An object of the present invention is to provide an image processing method and an image processing apparatus that make it possible to efficiently learn images having different identities. In learning and recognition using a hierarchical network, it is known that, based on experiences, a layer near the input functions as a feature extractor for extracting a feature that is necessary for recognition, and a layer near the output performs recognition by combining extracted features. Thus, performing learning by setting a higher learning rate to a layer near the input side of the hierarchical network than a learning rate in a layer near the output side in second learning processing as in an aspect of the present invention corresponds to mainly relearning (adjusting) a feature extraction portion in data sets having different identities. Accordingly, the difference between data sets can be absorbed, and learning can be performed more efficiently than in the case of simply performing transfer learning.

Abstract: An image processing apparatus according to a first aspect of the present invention acquires a first image and a second image in a first image acquisition mode, or a second image acquisition mode in which a second image acquisition ratio is higher than in the first image acquisition mode, on the basis of a detection result of a specific target (whether or not a specific target has been detected, what type of specific target). For example, in accordance with whether or not a specific target has been detected and the type of specific target, the first image and the second image can be acquired in the first image acquisition mode in a case where the necessity for acquiring the second image is low, whereas the first image and the second image can be acquired in the second image acquisition mode, in which the second image acquisition ratio is high, in a case where the necessity for acquiring the second image is high.

Abstract: Provided is an endoscope system capable of easily re-searching for a detected region of interest, and an operation method for the endoscope system. An endoscope system 10 includes an endoscopic image acquisition unit 54, a region-of-interest detecting unit 80, a position information acquisition unit 81, and a display unit 18. The endoscopic image acquisition unit 54 acquires an endoscopic image acquired by capturing an image of a lumen with an endoscope 12. The region-of-interest detecting unit 80 detects a region of interest in the lumen by using the endoscopic image. The position information acquisition unit 81 acquires position information of the region of interest detected by the region-of-interest detecting unit 80. The display unit 18 displays the position information of the region of interest.
