CMOS Sensors

CMOS stands for Complementary Metal-Oxide Semiconductor, which is a type of semiconductor technology used in the fabrication of integrated circuits.

CMOS sensors work by converting light into electrical signals through a process called photoelectric effect.

CMOS sensors consume significantly less power than CCD sensors, making them more suitable for portable devices and battery-operated applications.

CMOS sensors generally exhibit higher noise levels compared to CCD sensors, especially in low-light conditions.

Active Pixel Sensors (APS) are the most widely used type of CMOS sensor in digital cameras due to their high resolution, low power consumption, and fast readout speeds.

Full-frame CMOS sensors have a larger surface area than cropped CMOS sensors, which means they can capture more light and produce higher-quality images.

A Bayer filter is a color filter array that is placed over the CMOS sensor to separate light into different colors, allowing the sensor to capture full-color images.

Microlenses are used in CMOS sensors to focus light on individual pixels, thereby improving the light-gathering efficiency and image quality.

Readout noise is the amount of noise generated by the CMOS sensor during the process of reading out the electrical signals from the sensor.

The dynamic range of a CMOS sensor is the ratio of the brightest signal to the darkest signal that the sensor can capture without saturating or losing detail.

Quantum efficiency is the percentage of photons that are converted into electrical signals by the CMOS sensor.

Pixel size is the physical size of each pixel on the CMOS sensor, typically measured in micrometers (µm).

Resolution is the number of pixels on the CMOS sensor, typically expressed in megapixels (MP).

Frame rate is the number of frames per second that the CMOS sensor can capture, typically measured in frames per second (FPS).

The rolling shutter effect is the distortion caused by the sequential readout of pixels in a CMOS sensor, which can result in slanted lines or objects appearing distorted when the sensor is moved during exposure.
