Four misconceptions about image quality of image sensors! How many pitfalls have you stepped into? 2

Misconception 2: The more pixels there are, the better the image quality

This is a very common misconception. Many people believe that the number of pixels is a direct measure of image quality, so when purchasing a camera or phone, they always pursue higher pixels. However, the number of pixels is only one factor that affects image quality. In fact, excessive pixels on small sensors may cause inter pixel interference, reducing the overall quality of the image. In addition, factors such as image processing algorithms, dynamic range of sensors, and lighting conditions may have a more significant impact on image quality than pixel count.diode

Misconception 3: All sensors perform similarly under low light conditions diode

The image quality under low light conditions is a major challenge in measuring sensor performance. The performance of different sensors in low light environment varies greatly, which depends not only on the size of the sensor, but also on its pixel design, image processing technology, etc. Some sensors use special low light optimization techniques, such as Back Illumination (BSI) technology, which can capture more light in dim environments and improve image quality. Therefore, it cannot be generalized that all sensors have the same performance under low light conditions.diode
