CPC Class H04N

An endoscope device includes: a light source unit; an imaging device; a color filter in which a filter unit is arranged, the filter unit in which the number of filters which transmit light of a green wavelength band is equal to or larger than half the total number of filters and the number of filters which transmit light of a blue wavelength band is equal to or larger than the number of filters which transmit the light of the green wavelength band; and a noise reducing unit configured to select a pixel of interest based on used filter information determined according to the light emitted by the light source unit and a characteristic of each filter forming the color filter and detect motion between images captured at different times by using an electric signal output by the pixel of interest, thereby reducing a noise component included in the image signal.

The invention relates to an imaging device (E) comprising: at least one generator (1) of structured light; an emission first image guide (5, 5′) for uplinking the structured light from the generator (1) to an object to be observed; and a return second image guide (5′, 5) for downlinking the light reflected by said object to be observed to a system (2) for capturing said reflected light. Each of the two image guides (5, 5′) is able to uplink the structured light and downlink the reflected light, and the imaging device comprises an optical switch (3) configurable into three different operating modes.
