Hello,
What are the important differences between CMOS and CCD? I am studying the digital cameras

The main difference between CMOS (Complementary Metal-Oxide-Semiconductor) and CCD (Charge-Coupled Device) cameras is the way they capture and process images. CMOS cameras use multiple transistors at each pixel to convert light into electrical signals, while CCD cameras use a single large photodiode to convert light into electrons. This difference affects factors such as image quality, power consumption, and cost.
Generally, CCD cameras are better suited for low light conditions due to their larger photodiodes and higher light sensitivity. However, with advancements in technology, CMOS cameras have also improved in their ability to capture images in low light.
CMOS cameras tend to have lower power consumption than CCD cameras because they require less power to operate the multiple transistors at each pixel. This makes CMOS cameras more energy efficient and ideal for devices that have limited battery life.
Due to the differences in how they capture and process images, CMOS cameras tend to have more noise and lower dynamic range compared to CCD cameras. However, with advancements in technology, CMOS cameras have greatly improved in their image quality and can often match or even exceed the quality of CCD cameras.
In recent years, CMOS cameras have become more popular and are now used in the majority of modern devices such as smartphones, laptops, and digital cameras. This is due to their lower cost, lower power consumption, and improved image quality. However, CCD cameras are still used in certain applications that require high-quality images, such as scientific and industrial imaging.
