Medical skin examination device and method for enhancing and displaying lesion in photographed image

摘要

A medical skin examination device configured to diagnose a skin lesion includes: a first storage unit configured to store an original first skin image related to a dermoscopy structure imaged via a dermoscope; an image conversion unit configured to apply High Dynamic Range (HDR) conversion processing to the first skin image and obtain a second skin image in which the dermoscopy structure is made clear and salient; a second storage unit configured to store the second skin image; and a display control unit configured execute control so as to display at least one of the first skin image and the second skin image.

1. A medical skin examination device configured to diagnose a skin lesion, comprising:
a first electronic data storage device configured to store an original first skin image related to a dermoscopy structure imaged via a dermoscope; a central control unit including a central processing unit configured to apply High Dynamic Range (HDR) conversion processing to the first skin image and obtain a second skin image in which the dermoscopy structure is made clear and salient; a second electronic data storage device configured to store the second skin image; and a display control unit including a controller and a display configured to execute control so as to display at least one of the first skin image and the second skin image, wherein the central processing unit of the central control unit is configured to: generate multiple levels of pixel values by repeatedly applying smoothing processing and resolution conversion processing to a pixel value of one piece of the first skin image; correct, for each level, a pixel value of the first skin image based on a difference between the pixel value of the first skin image and the generated pixel value in each level; and execute control so as to construct the second skin image in which the pixel value of the first skin image is enhanced by utilizing a high-frequency component corresponding to a resolution in each level including the corrected pixel value.
