An infrared cut filter removable (ICR) module control apparatus includes a photoresistor, first to sixth electronic switches, an ICR module, a comparator, and a central processing unit (CPU). A first terminal of the photoresistor is connected to a power supply through a resistor. A second terminal of the photoresistor is grounded, and connected to the second to fourth electronic switches and the CPU through the first electronic switch. The second electronic switch is connected to the fifth and sixth switches. A node between the third and fourth switches is connected to a first input terminal of the ICR module and the non-inverting terminal of the comparator. A node between the fifth and sixth switches is connected to a second input terminal of the ICR module and the inverting terminal of the comparator. The CPU is connected to the output terminal of the comparator and connected to the first electronic switch. |
