- Image Sensor Type: CDS (CCD and CMOS are the two main technologies used in image sensors. CCD, the older of the two types, turns analog light signals into digital pixels. This conversion happens without distortion, resulting in high-quality images. Newer CMOS sensors use transistors at each pixel to move electrical charges. CMOS sensors are typically less expensive, but also require more light to create distortion-free images.)
