Embodiment 1
[0075] Figure 1 to Figure 26 Relating to embodiment 1 of the present invention, figure 1 is a conceptual diagram showing a signal flow when a spectral image signal is generated from a color image signal, figure 2 is a conceptual diagram showing an integral operation of a spectroscopic image signal, image 3 is an external view showing the external appearance of the electronic endoscope device, Figure 4 is showing image 3 Block diagram of the structure of the electronic endoscopy device, Figure 5 is showing Figure 4 The appearance diagram of the appearance of the shutter, Image 6 is shown configured in image 3 A diagram of the arrangement of color filters on the imaging surface of the CCD, Figure 7 is showing Image 6 A graph of the spectral sensitivity characteristics of the color filter, Figure 8 is showing Figure 4 A structural diagram of the structure of the matrix operation unit, Figure 9 is a spectrogram showing the spectrum of the light source, F...
Embodiment 2
[0291] Figure 28 It is a block diagram showing the configuration of the electronic endoscope device according to the second embodiment of the present invention.
[0292] Since the second embodiment is substantially the same as the first embodiment, only the points different from the first embodiment will be described, and the same components will be given the same reference numerals and their descriptions will be omitted.
[0293] In this embodiment, compared with the first embodiment, the light source unit 41 that controls the amount of illumination light is different. In the present embodiment, the control of the amount of light emitted from the light source unit 41 is performed by controlling the current of the lamp 15 instead of using a shutter. Specifically, in Figure 28 In the illustrated lamp 15, a current control unit 18 is provided as a light quantity control unit.
[0294] As the operation of the present embodiment, the control unit 42 controls the current flowi...
Embodiment 3
[0298] exist Figure 4 In the living body observation device, when acquiring the spectroscopic image, the light is interrupted at a predetermined time interval and the light quantity is controlled. Figure 5 The shutter 16 is controlled to reduce the amount of light. That is, the amount of light from the light source is reduced so that all color-separated signals of R, G, and B are captured within an appropriate dynamic range.
[0299] In Embodiment 3 of the present invention, an example is described in which movable light shielding members such as diaphragm springs and shutters, light shielding filters such as mesh turrets, and ND filters are used instead of Figure 4 The shutter 16 in the biological observation device.
[0300] Figure 29 An example of the diaphragm spring 66 is shown. The diaphragm spring 66 controls the amount of light by blocking light at predetermined time intervals by means of the diaphragm blade portion 71 which rotates around the central axis 67 a...
