CPC B60Q 9/008 (2013.01) [B60R 1/12 (2013.01); B60R 11/04 (2013.01); B60S 1/56 (2013.01); G01J 1/4204 (2013.01); G08G 1/167 (2013.01); H04N 23/54 (2023.01); H04N 23/55 (2023.01)] | 20 Claims |
1. A vehicular camera, the vehicular camera comprising:
a lens assembly having at least one lens;
a circuit board having a first planar side and a second planar side opposite the first planar side and separated from the first planar side by a thickness dimension of the circuit board, the circuit board having a first coefficient of thermal expansion (CTE);
an imager disposed at the first planar side of the circuit board, wherein the imager comprises a CMOS imaging array having at least one million photosensor elements arranged in columns and rows;
wherein the at least one lens of the lens assembly is aligned with the imager;
a bend-countering element disposed at the second planar side of the circuit board, the bend-countering element having a second CTE that is greater than the first CTE of the circuit board;
wherein the bend-countering element functions to counter temperature-induced bending of the circuit board; and
wherein, with the vehicular camera disposed at a vehicle, temperature-induced bending of the bend-countering element is in an opposite direction from temperature-induced bending of the circuit board.
