1. A vehicular display system provided in a vehicle comprising:
a first lamp configured to irradiate an outside of the vehicle with near-infrared light;
a second lamp configured to irradiate the outside of the vehicle with visible light;
a first camera configured to capture a first image of the outside of the vehicle irradiated by the first lamp;
a second camera configured to capture a second image of the outside of the vehicle irradiated by the second lamp, the second camera including an imaging range of the first camera;
a control unit configured to generate a third image in which a luminance of pixels of the first image corresponding to pixels of the second image is reduced, based on a luminance of the second image; and
a head-up display configured to display the third image generated by the control unit;
wherein the control unit is configured to generate a reference image in which a luminance of high-luminance pixels and a luminance of low-luminance pixels in the second image are relatively reversed, high transparency is set for pixels with high luminance, and low transparency is set for pixels with low luminance, and
wherein the control unit is configured to generate the third image by superimposing the reference image and the first image.
