Which type of image sensor is recognized for its low power consumption and reduced circuitry?

• A. CCD
• B. CMOS
• C. Foveon
• D. Photoelectric

Answer: (B)

The correct answer is CMOS. This type of image sensor is particularly noted for its low power consumption and reduced circuitry compared to other sensor types. CMOS (Complementary Metal-Oxide-Semiconductor) technology allows for integrating the processing circuits directly onto the image sensor chip, which effectively reduces the amount of external circuitry required. This integration leads to efficient power usage, allowing devices to run longer on battery power and generating less heat. Consequently, CMOS sensors are favored in many modern applications, such as mobile devices and CCTV systems, due to these benefits. In contrast, CCD (Charge-Coupled Device) sensors, while known for producing high-quality images, typically consume more power and require more complex circuitry. Foveon sensors and photoelectric sensors serve different purposes and applications, making them less relevant when discussing low power consumption and circuitry in the context of standard CCTV systems.
