Claims

First to third light sources for generating illumination light of first to third color components;
A modulator that modulates the light intensity of the illumination light of the first to third color components at first to third frequencies whose frequencies are different from each other;
A photosensor that photoelectrically converts reflected light from a subject obtained by irradiating illumination light of the first to third color components;
An image pickup apparatus comprising: a demodulator that demodulates signals of the first to third color components from an output signal of the photosensor.

In claim 1,
An imaging optical system that receives the reflected light from the subject and forms the subject on the imaging surface;
A light guide that has an incident end surface on a part of the imaging surface on which the subject is imaged and guides light incident from the incident end surface;
A scanning unit that scans the incident end surface of the light guide within the imaging surface;
An image forming unit that forms an image from an output signal from the photosensor that photoelectrically converts reflected light from the subject guided by the light guide;
An imaging apparatus comprising:

In claim 1,
An optical fiber that emits illumination light of the first to third color components as spot light;
An actuator that vibrates the optical fiber and scans a subject with the spot light;
An image forming unit that forms an image from an output signal from the photosensor that photoelectrically converts reflected light obtained by scanning a subject with the spot light; and
An imaging apparatus comprising:

In any one of Claims 1 thru | or 3,
The imaging apparatus, wherein the modulation unit modulates the driving currents of the first to third light sources to modulate the illumination light of the first to third color components.

In any one of Claims 1 thru | or 3,
The modulation unit includes first to third optical elements for modulating light intensity of the illumination light of the first to third color components from the first to third light sources, and the light intensity modulation. An image pickup apparatus that supplies a modulation signal for performing to each optical element of the first to third optical elements.

In any one of Claims 1 thru | or 5,
The modulator modulates the intensity of illumination light of the first to third color components based on the first to third carrier signals of the first to third frequencies,
The imaging apparatus, wherein the demodulator detects the signals of the first to third color components from the output signal of the photosensor based on the first to third carrier signals.
