The camera sensor is larger than the mobile phone, so the picture quality is better, and there is relatively little noise when shooting in dark light;

2. The sensor is large and the area of a single pixel is also large. The high pixel sensor has small single pixel area and poor image quality;

3. The structure of mobile phone lens is simple, there is no optical zoom, most of them are resin lenses, and the cost is low. The lens of card machine is much better, generally with optical zoom;

4. Because the mobile phone sensor is small and the actual focal length of the lens is very short, it is difficult to take photos with blurred background;

5. Some high-end card machines can be operated manually with strong playability;

6. The pixels are large, and the size of the photos taken is large, which is convenient for printing large-size photos and cutting. To be clear, the pixel height does not mean that the photo is clear, but the role of the lens is the most important. Because of the cost, it is impossible to make the mobile phone lens too high-end.

Of course, mobile phones also have advantages, which are more convenient and fast in network sharing, and can basically be shared instantly. The quality of online pictures is not high, and mobile phones are competent. At present, some mobile phone sensors are relatively large, and basically do not lose the card machine. However, due to the size, there is no optical zoom, which is the biggest shortcoming of mobile phones.
