Title: Vehicular imaging apparatus
Inventor: SUGISAKA KENICHI
IPC: H04N5/225
Filed: 2020-02-07
Abstract: To provide a vehicular imaging apparatus which can quickly increase the temperature of a heater.SOLUTION: In a vehicular imaging apparatus 10, an electric circuit including a heater 26 is serially connected to a resistance member 32. The resistance member 32 is heated with the electric conduction, and an electric resistance value is increased with the temperature rise due to the heat generation. Therefore, when the resistance member 32 is heated and the temperature is sufficiently increased, a current value of a current flowing in the heater 26 can be reduced and the heat generation of the heater 26 can be suppressed. Also, since the electric resistance value is increased due to the temperature rise in the resistance member 32, the current having the large current value can be made to flow in the heater 26 at the start of application of voltage to the electric circuit including the heater 26 and the resistance member 32, and the temperature of the heater 26 can be quickly increased.SELECTED DRAWING: Figure 1
