1. A camera mount structure in a vehicle, comprising:
- a camera for imaging a driver'"'"'s face, the camera having a lens with a sensitivity in a near-infrared light area;
a meter device with a dial plate; and
a pointer that is rotatable relative to the dial plate and rotatable within a rotation range, whereinthe dial plate has speed numerals and scale patterns arranged around an axle of the pointer, the speed numerals and scale patterns being arranged in concentric arc shapes having concave sides facing downward;
the camera is positioned on a back side of the dial plate of the meter device such that the lens of the camera is disposed on a side of the dial plate opposite the speed numerals and scale patterns, is outside of the rotation range of the pointer, is lower than the axle of the pointer, and is between lowest-most endpoints of the concentric arc shapes of the speed numerals and scale patterns; and
a portion of a surface of a front side of the dial plate that faces the lens of the camera has a treatment that allows a near-infrared light to pass through the dial plate, but prevents a visible light from passing through the dial plate.

Abstract
A face camera mount structure in a vehicle has a camera for imaging a driver'"'"'s face being disposed on a reverse side of a dial at a portion that does not interfere with a speedometer design portion on the dial. A camera facing portion of the dial that faces a lens of the camera is covered with a print of a near-infrared light passing ink that selectively passes a near-infrared light. The high transparency factor of the near-infrared light through the ink makes it possible for the camera to image a sufficiently bright near-infrared light image without being recognized by a driver of the vehicle.
