Benefits of technology

The invention is an endoscopic device that uses multiple light sources to capture images of a subject. The device adjusts the intensity of the lights to optimize color accuracy and diagnostic effectiveness. This ensures that the color tone of the captured images remains stable even when the intensity of the light sources changes. This improves the quality of the observation image and makes it easier to diagnose and treat abnormalities during endoscopy.

Problems solved by technology

Further, if a predetermined image processing is performed to the observation image, an intended image may not be obtained.

Embodiment Construction

[0020]Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

[0021]FIG. 1 is a block diagram of the configuration of an endoscopic device according to an exemplary embodiment of the present invention, and FIG. 2 is an external view illustrating a specific configuration example of the endoscopic device.

[0022]An endoscopic device 100, as shown in FIG. 1, includes an endoscope 11, a control device 13, a monitor 15, and an input module 17 such as a keyboard or a mouse that inputs information to the control device 13. The control device 13 is constituted by a light source device 19 that outputs illuminating light and a processor 21 that performs signal processing of an observation image.

[0023]The endoscope 11, as shown in FIG. 2, includes a main body operating module 23, an inserting module 25 that is coupled to the main body operating module 23 to be inserted into the subject (body cavity), and a universal cord 27 that i...

Abstract

An endoscopic device that irradiates a plurality of illuminating light having different spectrums from each other onto a subject at a front edge of an endoscope inserting module and captures the subject to obtain an observation image The endoscopic device includes an illuminating module, an imaging module, a light intensity ratio control module, and a color tone correcting module. The illuminating module generates the plurality of illuminating light. The imaging module captures the subject and output an image signal of the observation image. The light intensity ratio control module controls the illuminating module to irradiate the plurality of illuminating light onto the subject with a set light intensity ratio by setting the light intensity ratio of the plurality of illuminating light. The color tone correcting module corrects the color tone to obtain the observation image with substantially the same color tone even though the light intensity ratio is changed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Japanese Patent Application No. 2011-174818 (filed on Aug. 10, 2011), the entire contents of which are hereby incorporated by reference.BACKGROUND[0002]1. Technical Field[0003]The present invention relates to an endoscopic device.[0004]2. Related Art[0005]An endoscopic device that is used in the medical field performs a normal observation that observes a subject image almost same as the observation by naked eyes by irradiating white light onto a subject in a biological body as well as a narrow band observation that observes a subject image by irradiating narrow band light having narrower wavelength band than the light irradiated during the normal observation. The narrow band observation observes the blood capillary or a micro pattern of a superficial portion of the mucous membrane in the biological body with a good contrast and helps for an early detection of lesions.[0006]The endoscopic device that ...
