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>

At the moment, cell phone photography and camera photography presented different developments. In terms of hardware, the camera had an advantage in terms of shooting hardware capabilities. It could be equipped with a variety of lenses and could be freely changed to meet different shooting needs. The equivalent focal length of the mobile phone's main camera was basically fixed at 23 - 24mm, which was a wide-angle lens. This limited its ability to display layering. Although there were hardware upgrade concepts such as the bottom sensor, due to factors such as the thickness of the phone and the cost, it was difficult to make a revolutionary breakthrough in the hardware in the short term. To some extent, it had already touched the physical ceiling. In terms of the market, the digital camera market had been monopolized by Japanese brands. However, with the popularity of smart phones, the shipment of digital cameras continued to decline. The decline was obvious from 2020 to 2021, and it was gradually replaced by mobile photography functions. In terms of convenience, cell phones had an obvious advantage. The phone was easy to carry, and it was also more convenient to post content on social media. It also had its own post-production function. All kinds of filter and algorithm buffs allowed photography novices to take good photos. The camera, on the other hand, required the photographer to complete a lot of post-production work. In terms of shooting functions and effects, the camera performed better in some professional scenes. For example, when taking photos dedicated to products, the phone may have problems such as ghosting, poor background blurring effect, and inability to freely control the degree of blurring. The details are not as good as the camera (such as the fine structure of the surface of the object). However, if the user had photography aesthetics and skills, they could also take high-quality photos with their mobile phone. In some scenes, the camera might not be used because of its troublesome operation. For example, taking photos of roadside flowers at the last minute, the mobile phone was more convenient. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

I recommend a few horror novels. 'Haunted House Night Talks' was a collection of short horror stories. Don't read alone at night. Every story is scary. The writing style was not bad.

The residents had to follow the instructions written in blood to complete the mission in order to survive in the apartment.
