CMOSkennojen

CMOSkennojen refers to Complementary Metal-Oxide-Semiconductor (CMOS) image sensors. These are semiconductor devices that convert light into electrical signals, forming the basis of modern digital cameras and imaging systems. Unlike older CCD (Charge-Coupled Device) sensors, CMOS sensors read out pixel data individually, offering advantages in terms of power consumption, speed, and integration capabilities.

The fundamental principle of a CMOS image sensor involves photodiodes or phototransistors located at each pixel. When light strikes these photosensitive elements, it generates an electrical charge proportional to the intensity of the light. This charge is then converted into a voltage. Each pixel in a CMOS sensor also contains additional circuitry, such as amplifiers and analog-to-digital converters, allowing for direct readout of the signal.

CMOS sensors are widely used due to their lower manufacturing cost, reduced power requirements, and the ability to integrate other camera functions, like signal processing, directly onto the same chip. This has led to their dominance in a vast range of applications, from smartphones and digital cameras to security cameras, automotive sensors, and scientific imaging. Their continuous development has resulted in higher resolutions, improved low-light performance, and advanced features like phase-detection autofocus.
