FIELD: physics.
SUBSTANCE: imaging device includes a display for displaying an image section and a video processing section for gradually lowering the output power to the image. The output power is gradually reduced for light radiation with a wavelength in the range of 446 nanometers to 483 nanometers of light radiation. And the gradual reduction is performed after the user observes the image.
EFFECT: reduction in the degree of the user fatigue who observes the colour image by gradually lowering the output power of a separate range of light waves, which does not cause degradation of the video signal display.
