The application fields of wide dynamic cameras
The application of wide dynamic range technology in camera systems makes dark areas brighter, softens bright areas in the scene, alters visual effects, and provides useful and recognizable images. Wide dynamic cameras typically use special digital signal processing circuits. Wide dynamic cameras first expose objects in bright areas at an appropriate shutter speed, and then expose objects in dark areas at an appropriate shutter speed. After getting drunk, two images are recombined on one image using a digital signal processing chip to expand the dynamic range that may be processed, so that bright and dark objects can be clearly seen.

Definition of camera module resolution and pixels
The 4K resolution of Niu Jinfeng refers to the number of pixels per row in the horizontal direction reaching or approaching 4096, regardless of image scale. Of course, this is not the only definite pixel ratio, for example, 4096 x 3112, 3656 x 2664, 3840 x 2160 all belong to the category of 4K resolution.

How to distinguish between binocular, monocular, and 3D structured light cameras for facial recognition
The definition of binocular cameras is based on a face recognition solution using binocular cameras. One camera captures visible light photos and one camera captures near infrared photos, and the captured faces are recognized. Accurate identification and localization of key feature points such as eyes, ears, and noses are carried out, and various spatial information such as pupil distance, nose height, and distance from eyes to mouth to ear are calculated. The calculation error is less than 1mm, which can effectively resist fraud in photos, videos, and other fields. Accurately detect whether it is a "living person" or a "real person" to ensure the accuracy of * * detection.

Three elements to pay attention to when designing a car stereo camera
What issues should be noted in the industrial design of binocular cameras? A binocular camera, as the name suggests, is a new type of security monitoring product that is equipped with two cameras, just like our human eyes. It is also a company that has been providing product design for the security industry for a long time. Below, I will explain from three aspects what to pay attention to when designing a binocular camera?

What is the quality of binocular camera products? Introduction to the advantages of binocular cameras
A new type of security monitoring product, the binocular camera, has emerged in the security market. It is a new product developed to meet the monitoring needs in different monitoring environments. It uses pixel analysis to identify the monitoring scene, and then uses new scientific methods to restore the monitoring scene. Compared with a single camera, it overcomes the influence of light intensity and can more realistically restore the quality of monitoring. As a security camera, many people do not have a special understanding of the function and performance of this product, and may be skeptical of its working ability. So, is the quality of the binocular camera product good?
