The quality of the camera sensorJudging the quality of the camera's sensor required a combination of many factors.
From the perspective of the number of pixelation, the number of pixelation would affect the resolution of the image. For example, the different series of pixelation under the Samsungs were different. The HP series had 200 million pixelation, the HH series had 100 million pixelation, and so on. Different pixelation would have different performances in different scenarios.
The size of the sensor was also very important. There was a saying that "the biggest one can crush a person." For example, the size of the SonyT- 900, model 1/0.98, was larger. However, it could not be judged solely based on the size. The difference in the shooting effect of different sizes of sensors equipped with different mobile phones was also affected by other factors.
Different types of sensors had their own characteristics. The common ones were the two types of CCMs and CMOMs. The light captured by the pixel-like light in the CCD-sensor was then moved to the edge of the chip and converted into a digital signal; the light of the CMOS-sensor was converted into a digital signal at the pixel-like light. Under the same conditions, the power consumption of the CMOS-sensor was lower. In theory, the battery life of a portable camera equipped with a CMOS-sensor might be longer, but the actual situation was still limited by many factors.
In addition, the actual imaging effect had a lot to do with the sensor, but it also had to do with the light source, the amount of light, the path, the anti-shake ability, the zooming focal length, and the mobile phone system algorithm. Even if the sensor hardware parameters were good, other aspects would affect the overall effect, and poor hardware parameters would limit the upper limit of the overall performance.

DSLR sensor repairFirst, the phenomenon that often occurs when the image sensor is damaged: black screen phenomenon, flower screen phenomenon, screen color reproduction is not correct, the color of the upper half of the screen is different from the lower half, and the upper half of the screen has an image and the lower half has no image.
The reason for the damage to the image sensor was as follows:
1. Quality issues: The early image sensors and internal circuits were immature and prone to malfunction. Although there are improvements now, problems may still occur.
2. [Lifetime: There is a limit to the number of uses. If used too much, it may be damaged. For example, the camera in the photo studio is used frequently and may be scrapped after more than a year.]
3. " Inappropriate use: Do not bump, squeeze, fall, or enter water. Shooting against the sun or strong light may burn the image sensor.
4. " Inappropriate dust removal: Ordinary photography enthusiasts lack the technology and equipment to clean, and improper handling may damage the sensor.
If the image sensor's circuit malfunctioned, it could usually be repaired, but most of the internal problems could only be replaced. Changing the image sensor of a digital single-lens reflex camera usually cost more than half the price of the camera.
