[0029] figure 1 It is a figure showing the structure of the endoscope apparatus 1 of 1st Embodiment. Such as figure 1 As shown, the endoscope device 1 of the first embodiment includes an electronic endoscope (hereinafter simply referred to as an endoscope) 2 inserted into a body cavity for endoscopic inspection, and a light source for supplying illumination light to the endoscope 2 . device 3. In addition, the endoscope device 1 as a medical device further includes a video processor (hereinafter referred to as a processor) 4 as an endoscope video signal processing device for driving an imaging unit built in the endoscope 2. , and signal processing is carried out on the output signal of the imaging unit; Endoscopic image.
[0030] The endoscope 2 has: an ID generating part 6 for generating unique identification information (ID) in the endoscope 2, an elongated insertion part 7, an operation part 8 provided at the rear end of the insertion part 7, and an operation part 8 f...

[0120] In the above-mentioned example, the light source device 3 is configured as follows: emit white light in the white light observation mode, emit predetermined narrow-band light in the narrow-band light observation mode, and receive the return light by the imaging element. As a modified example, as The light source device of the lighting unit may emit only normal light as white light, and generate an image signal equivalent to return light of narrowband light as special light through known so-called spectrum estimation processing in the narrowband light observation mode. Regarding spectral estimation processing, for example, Japanese Patent Application Laid-Open No. 2003-93336 discloses an electronic endoscope apparatus that performs signal processing on an image signal formed of illumination light in the visible light region to generate a discrete spectral image, Obtain image information of biological tissue.
[0121] In the case of this modified example 1, figure 1 The...
Deformed example 2
[0124] In the above example, the color discrimination circuit performs color discrimination based on the RGB color system, but it may also be based on other color systems such as CIEL*a*b* (Elster Esuta BeStars) color system, LUT color system, etc. distinguish.
[0125] For example, it is also possible to perform color discrimination using the hue angle θ in the CIEL*a*b* colorimetric system which is one of UCS (Uniform ColorSpace: Uniform Color Space). In this case, with Figure 4 In a table similar to the shown table TBL, a plurality of hue regions are defined based on the range of the hue angle, and whether or not each pixel belongs to a predetermined region within the defined plurality of hue regions is discriminated, and color correction as described above is performed. For example, color correction processing and the like are performed only on pixels whose hue angles of the L*a*b* colorimetric system fall within the range of −45° to 45°.
[0126] Also, color discrimina...
