focused on the target

There were the following ways to focus the camera: 1. ** How the autofocus device works ** - Some cameras had autofocus devices that worked with infrared or ultrasound. After the infrared rays or ultrasonic waves returned to the object, they were received by the camera's infrared sensor or ultrasonic sensor to measure the distance. Then, the camera's focusing device was driven to focus according to the measured distance. - Another method was to use a rangefinder based on the principle of triangulation to measure the distance between the camera and the subject. Then, the measured distance was input into the camera's processor for calculation, and the lens 'focus motor was controlled to focus according to the calculated distance. When the camera was aimed at the subject, it automatically focused without the need for the cameraman to manually adjust it. 2. ** Principle of contrast focusing (CDaF)** - When the image was out of focus and blurred, the contrast of the image would decrease, and the difference between the maximum and minimum brightness would become smaller. Only when the focus was OK would the contrast be the strongest and the difference be the largest. The contrast focus was based on the difference in contrast, but this method of focusing was slow. When the camera was out of focus, it couldn't tell whether it was in front of or behind the focus. It didn't know whether the lens should be extended forward or retracted. The camera would move the lens back and forth to confirm that the focus was complete. 3. ** Phase-Based Focus (PDAR) Principle ** - It could know whether the defocus was before or after the focus, which meant that it knew whether the lens should be extended forward or retracted. This autofocus technology responded faster than contrast focus (CDaF). 4. ** Operating principle of infrared autofocus system ** - When the camera was turned on, the "infrared autofocus system" began to work. The system emitted beams of infrared rays, scanning the target horizontally from near to far. At the same time, the electronic system controlled the camera lens to move back and forth from near to far. Once the infrared beam hit the target, it would immediately reflect back, triggering the electronic system to adjust the camera lens to the best position through a mechanical device, thereby automatically completing the "focus." <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Shooting was an activity that involved shooting a target. In military training, for example, new recruits would undergo target practice, including shooting essentials such as three points and one line, leveling with the gap, intentional shooting and unintentional firing, etc. After target practice, they would undergo live ammunition shooting assessment. Before live ammunition shooting, they might also experience shooting to familiarize themselves with the gun. In countries where guns were banned, such as China, although people couldn't hold guns at will, many people would go to foreign shooting ranges to experience shooting when traveling abroad. Some foreigners found that although the China were banned from shooting, they showed excitement, proficiency, and accuracy when shooting at the shooting range. Some people thought that this might be related to the China playing toy guns and shooting games when they were young, and using chopsticks to exercise their sense of linear space. Other than that, there were also web games like " CS Classic Map Shooting " that used shooting as their main theme. Moreover, there was also the Hanwang AI electronic target practice with the intelligent voice target reporting function.
