Why do cell phone cameras always have wavy lines?
The main reasons for the wavy lines appearing on the phone camera were as follows: 1. The refresh rate of the mobile phone's previews was not synchronized with the refresh rate of the captured object. For example, when using a mobile phone to shoot a TV or fluorescent lamp, since the fluorescent lamp's frame rate was generally 50HZ, if the mobile phone's previews refresh rate was not synchronized with the fluorescent lamp's frame rate, flashing ripples would appear. In this case, you can set the camera's flicker prevention function to 50HZ to avoid it. 2. Moire fringe effect: Moire fringe is the visual result of interference between two lines or two objects at a constant angle and frequency. When a camera was used to take a picture of a television screen, the previews would show light and dark stripes due to the moire pattern phenomenon. 3. Moiré phenomenon: The Moiré phenomenon is a visual phenomenon. It is an interference pattern that occurs on an object with a certain interval. It refers to the interference pattern produced by the overlapping of two equal amplitude sinewaves with similar frequencies. 4. Photosensor interference: When the camera takes a picture, the sensor may be interfered with, resulting in ripples on the review interface. Read more exciting novels for free
Dual cameras, cell phone camera, video
Dual-camera phones had many advantages in taking photos and videos. In terms of taking photos, different brands of dual-camera phones had their own characteristics. For example, Huawei nova8 Pro front dual camera, its 32-million-pel ultra-wide-angle selfie video lens and 16-million-pel portrait lens combination, 100° ultra-wide-angle lens can provide a wide picture, portrait lens can achieve portrait blurring effect, also has super anti-shake function to stabilize the picture, built-in three three-dimensional radio microphones and self-developed AI sound algorithm to clearly record sound, and support beauty, filter function. The front double camera of the Vivo S7 could shoot 4K short films. The shooting ability of the front double camera was strong, and the 4K short films shot could be on the big screen of the cinema. In terms of video shooting, the iPhone series performed well. For example, the iPhone 11 series was easy to take photos when recording videos, and it supported the function of quickly switching cameras. The iPhone 12/13 series and the latest models supported high-quality photos while recording 4K videos. They were equipped with more advanced camera systems and image processing algorithms, making the picture clearer and more detailed. They also supported night mode shooting and recording, as well as Dolby Vision HVR video recording.

The difference between cell phones and DSLR cameras
When shooting metal, there were many differences between cell phones and DSLR cameras: ###1. Image Quality 1. ** Pieces and Details ** - DSLR cameras usually had a larger sensor size and a relatively lower density of the image. They could capture finer details when shooting metal. For example, Canon's Eos 90D (18 - 200mm) and other single-lens reflex cameras had sensors that could record rich details such as metal surface texture. Although the cell phone had a high number of pixelation, when taking pictures of metal, due to the small size of the sensor and the high density of the pixelation, when zooming in to see the details of the metal, there might be blurriness or loss of details. 2. ** Noisy Control ** - When shooting metal in low light conditions, DSLR cameras could better control noise due to their larger sensors and better image processing capabilities. And when the phone shot metal under high sensitivity (USB), it was easy to produce more noise, which affected the appearance of the metal texture. ###2. Light and color 1. ** Light ** - Through different lenses and optical equipment such as a larger aperture, a single-lens reflex camera could produce a unique light effect when shooting metal. For example, old shots might produce dark corners, unique blurring of the background, and other effects, creating a special light and shadow atmosphere of metal. Mobile phones relied more on algorithms to simulate these effects, and they might be a little stiff in expressing the light texture of metal. 2. ** Color Restoration ** - The DSLR camera could accurately restore the true color of metal by changing different lenses and adjusting the white balance. Although the phone had some color modes, in some cases, it might be overly beautified or biased, resulting in the color of the metal being inaccurate. ###3. The effect of background blurring 1. ** Physical Illusion ** - DSLR cameras could achieve a natural background blurring effect through a large aperture lens. When shooting metal products, it could highlight the main metal, making the background soft and blurred, showing the three-dimensional feeling of metal. For example, when shooting metal jewelry, the messy background could be blurred out to make the jewelry stand out more. 2. ** Arithmetic Virtual ** - Mobile phones used algorithms to achieve background blurring. It might not be accurate enough when dealing with metal edges, and it was easy to cause excessive blurring or unnatural blurring, especially when the contrast between metal and background was large. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Can cell phones replace cameras now?
At present, cell phones could not completely replace cameras. In terms of image quality, the clarity of the camera was determined by the lens and sensor, and the restrictions on the body were relatively small. Due to the limitations of the body, the sensor and lens of the mobile phone were small. Although the resolution could be made larger, it was difficult to improve the clarity. Moreover, the aperture was small, and there would be a smear phenomenon when the light was not good. In terms of frame, the camera's image ratio was fixed at 16:9 or 4:3, while different models of mobile phones had different frame proportions. In terms of price, digital cameras were expensive, while mobile phones were relatively cheap. In terms of function, the camera was specially used for shooting, while the phone had a camera function, but it also had many functions such as making calls and socializing. There were also differences between the two in terms of video recording. For example, there were differences in color, details, and video capture. There might be problems with the dark image, loss of information, and obvious sharpening when shooting videos with a mobile phone. Moreover, there was a gap between the movie mode of a mobile phone and that of a professional camera. In terms of the size of the image sensor, the camera could capture more light, its processor could process more environmental information, and the photos taken were less noisy and more detailed. Although the size of the phone sensor was gradually approaching the camera, there were still limitations. The camera could change key exposure settings such as aperture and shutter speed. These settings on the phone were only software simulations, and the flexibility and image quality were not as good as the camera in shooting fast movements, fine-tuning brightness, or obtaining depth of field effects. The size of the camera lens was larger than that of the mobile phone, so it could obtain a clear depth of field. The camera could be zoomed through the lens hardware, and the mobile phone could only be zoomed through the software, which would cause the image quality to decrease. In addition, when the phone recorded videos, the battery would drop quickly and the storage space would be full easily. The camera could take more photos without such problems. Although the phone had a video stabilization function, it would cut the video and reduce the quality. The camera could stabilize the video with a tripod. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
