Three technical indicators of the camera include
1, Resolution: Resolution refers to the degree of detail that the camera can capture and display the image. Usually expressed in pixels. The more pixels, the higher the resolution and the clearer the image. Resolution determines the smallest detail that the camera can distinguish, and it is an important index to measure the image quality.
2. Sensitivity: Sensitivity refers to the degree of response of the camera to light, usually measured by the lowest illumination. The minimum illumination refers to how dark the camera can still output a clear image. High-sensitivity cameras perform better in low illumination, and can take clear images without much external illumination.
3. SNR: SNR refers to the ratio of effective signal to noise in the camera output signal. The higher the signal-to-noise ratio, the stronger the effective signal, the lower the noise and the better the image quality. In the case of low signal-to-noise ratio, noise may appear in the image, which affects the clarity and impression of the image.
