What aspects of Starlight-class intelligent HD cameras need to be improved?

With the advancement of technology, the development of the security field is also accelerating, and various intelligent high-definition cameras are widely used in various fields. The cameras are different according to different levels of configuration. The industry recognizes 0.001Lux and the following as star-level cameras. Because the star-level camera technology is mainly affected by factors such as lens, image sensor, and back-end image processing technology, major security manufacturers are also upgrading from the following aspects:

1, good image processing technology: the previous camera uses the traditional 2D algorithm to achieve the noise reduction function, and now the 3D noise reduction technology, based on the original frame noise reduction, by comparing the image of the two frames before and after The filtering process is used to find the noise position and gain control, and the 3D digital noise reduction function can reduce the noise interference of the weak signal image. Since the appearance of image noise is random, the noise appearing in each frame of the image is not the same. 3D digital noise reduction automatically filters out non-overlapping information (ie, noise) by comparing adjacent frames. With 3D noise reduction camera, image noise will be significantly reduced, and the image will be more clear and clear, thus showing comparison. Pure and delicate picture.

2, the use of large aperture lens: lens is an important part of the camera component, its role in low-light monitoring application technology is to focus the camera on the target light, the key to low-light application and technology here is the lens diameter The larger the amount of light entering the lens, the larger the aperture of the lens can effectively increase the amount of light entering, thus giving the camera an ideal low illumination effect.

3, the choice of large target sensor: the essence of the camera is to convert light energy into electrical energy, and the core component of the quantification is the sensor, the role of the sensor is to photoelectrically convert the different intensity of light transmitted to it, and convert it into voltage information. Generate digital image information. The part of the sensor that receives light is naturally the core of the core. If the camera of the same resolution has a larger target surface area, the larger the amount of light per unit pixel, the stronger the noise suppression capability, and the better the image quality when shooting at low illumination.

If the intelligent high-definition camera can get more improved performance improvement in these aspects, it can solve the problem that the previous high-definition camera has a small monitoring range, the night monitoring picture is not clear, the cruise cannot be cruised, and the lens cannot be zoomed in and out. Large-scale high-definition image quality monitoring sites such as rivers, forests, highways, railways, airports, scenic spots, streets, stations, large venues, and residential areas.
