kuvakennolle

kuvakennolle is a Finnish term that translates to "image sensor" in English. It refers to the electronic component in a digital camera or other imaging device that captures light and converts it into a digital signal. This signal is then processed to create a photograph or video.

There are two main types of kuvakennolle: CCD (Charge-Coupled Device) and CMOS (Complementary Metal-Oxide-Semiconductor). CCD sensors were historically more common, known for their excellent image quality and low noise. However, CMOS sensors have become increasingly prevalent due to their lower power consumption, faster readout speeds, and lower manufacturing costs. Modern smartphones, DSLRs, and mirrorless cameras predominantly use CMOS sensors.

The size and resolution of a kuvakennolle are key factors determining the quality and detail of an image. Larger sensors generally perform better in low light conditions and offer a greater dynamic range, allowing for more detail in both highlights and shadows. Higher resolution, measured in megapixels, indicates the number of individual pixels on the sensor, which translates to the potential for greater detail in the final image. The sensitivity of the kuvakennolle to light, often referred to as ISO, also plays a crucial role in its performance, especially in varying lighting situations.
