The sensor is one of the most important parts of a camera as it greatly affects the final image quality. Important factors to consider include the size of the sensor as well as the number of pixels.

Although more pixels generally means better image quality, the size of the sensor is also important. Generally, if you have two cameras with the same number of pixels, but one has a larger sensor than the other, the one with a larger sensor should produce better-quality images. 

important parameters

  • Sensor size (cm) - the bigger the size, the better the resulting image/video
  • Sensor resolution (Megapixels)

Basic cameras are often equipped with an 800,000-pixel chip.

The three-chip design is common in professional and semi-professional cameras. The three chips cooperate with the glass prism, which divides light into three directions. Each chip is in responsible for one part of the basic RGB colour spectrum (green, red, and blue).

CMOS sensors provide better, truer colour dynamics. While CMOS sensors don't produce the overall quality of three-chip sensors, they do offer better performance in poor light conditions.
