The smaller the minimum illumination, the lower the illumination requirement for the shooting environment, the better the image can be obtained under darker lighting conditions, and the more adaptable. The minimum illumination is the lowest level that can be achieved with digital processing techniques such as maximum aperture, maximum gain, and dual pixel readout. The electronic means increased the sensitivity, but the sharpness decreased. At present, the minimum illuminance is mostly theoretically calculated.
The minimum illumination Lux is a way to measure the sensitivity of the camera. In other words, the camera can see the available images in dark conditions. Lux Lux is a metric unit used to measure the amount of light projected onto an object. It is called a lumen in the UK and a Lux in Europe. Specifically, 1 Lux is equal to the amount of light that a candle projects from a surface of 1 square meter on a surface of one square meter. 10 Lux is equal to the amount of light that 10 candles project from the surface of the object to the surface of the object.
The 1Lux camera is said to capture a normal-light image about 3 meters away from the object under the light of a candle. Many cameras on the market today can do it. The problem is that the quality of the resulting image is not good, the picture is full of snow-like noise, and the clarity and color reproduction are very poor.
The main effect of the picture is the concentrating power of the DV lens. 1Lux is the size of the incident light that is projected onto the object. It is also the light that your camera captures and records. Light that is incident on an object and reflected by the object to the lens. The surface of a light, reflective object is better than the surface of a dark object in low light. In general, a digital camera with a larger size of a photosensitive device can produce excellent image quality in a low Lux environment, and a 3CCD can also be in a low Lux.
