Title:
ON-VEHICLE CAMERA DEVICE
Document Type and Number:
Japanese Patent JP2023030279
Kind Code:
A
Abstract:
To provide an on-vehicle camera device which can reduce processing load for determining a power supply source and shorten time taken for determining the power supply source.SOLUTION: An on-vehicle camera device becomes an active state with power supplied from one of a first power source and a second power source. Furthermore, the on-vehicle camera device is communicably connected to a plurality of first power source system devices configured so that power can be supplied from only the first power source of the first power source and the second power source. When the on-vehicle camera device receives a determination signal transmitted every time prescribed transmission time is elapsed by the first power source system devices which become active states by being supplied with power from the first power source at least once, the on-vehicle camera device determines the power supply source of the on-vehicle camera device as the first power source and operates in a first mode, and operates in a second mode having power consumption smaller than that in the first mode when the power supply source is the second power source.SELECTED DRAWING: Figure 3
