Problems solved by technology

[0004] However, when the color tone and lightness of the skin color part of the non-disease area are different, when the doctor obtains insights based on visual observation, he only focuses on the difference, and it is difficult to grasp the difference in the diseased area
[0005] Therefore, for example, color correction is performed as described in Non-Patent Document 1, or brightness correction is performed as described in Patent Document 1, but in the former case, when the color information used for correction is measured, Since the measurement is also performed on the central part of the diseased area, the robustness is low, and the color correction is performed by the gray color false, so there is a problem that the corrected skin part becomes pale and unnatural
In addition, in the latter case, the excessive or insufficient brightness of the skin-colored area caused by both the light source condition and the exposure condition is corrected, but the inherent characteristic processing corresponding to the application is not included. Perform high-precision diagnosis

[0043] (Configuration of the first embodiment)

[0044] Such as figure 2As shown, the processing unit 12 of the first embodiment includes a color correction processing unit 121 . In order to perform color correction, the color correction processing unit 121 sets the peripheral portion of the photographed image other than the central portion with a high probability of disease as the measurement area, and sets the correction conversion target as skin color, and performs color correction processing. At this time, the color correction processing unit 121 regards the central part as the central circle of the photographed image, and obtains the Lp norms of the corresponding pixels for each RGB in the measurement area except the central circle, and uses the L2 norms of eR, eG, and eB To become 1, the coefficient k is used for normalization. After multiplying ec by 3^(1 / 2), take the reciprocal to set the color gain. Multiply the gain coefficient of RGB with each pixel to perform the...

[0097] (Configuration of the third embodiment)

[0098] Next, a third embodiment will be described. In the third embodiment, the dermoscopic image subjected to the color correction processing (normalization) of the first embodiment and / or the brightness correction processing (normalization) of the second embodiment is sent to a recognition system composed of a neural network. Machine input, using the results of machine learning to make inferences about the unknown disease of the subject of investigation. In this case, after normalizing the color and / or brightness of the skin color portion of the dermoscopic image, the normalized target value is subtracted and input to the neural network.

[0099] Figure 12 It is a block diagram showing the configuration of a diagnostic device 100A according to the third embodiment of the present invention. Such as Figure 12 As shown, a diagnostic device 100A according to the third embodiment of the present invention is connected to an im...

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 5 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.

Description

[0001] This application is based on Japanese Patent Application No. 2016-171595 filed on September 2, 2016 and Japanese Patent Application No. 2017-081594 filed on April 17, 2017. The specifications of Japanese Patent Application No. 2016-171595 and Japanese Patent Application No. 2017-081594, the scope of claims, and the entire drawings are incorporated herein by reference. technical field [0002] The present invention relates to a diagnosis support device, an image processing method of the diagnosis support device, and a storage medium storing a program. Background technique [0003] As a diagnosis of skin lesions, inspection must be carried out, and more information can be obtained. However, it is even difficult to distinguish moles from plaques, and also difficult to distinguish benign tumors from malignant tumors only with the naked eye and a magnifying glass. Therefore, a dermoscopic diagnosis using a camera with a dermoscopic camera to photograph the lesion is perfo...
