The front camera and the back camera take different pictures
There was a difference between the front camera and the back camera. In terms of the quality of the lens, in many mobile phones, the main camera was often the rear camera. Its resolution and shooting quality were usually better overall, and the cost was higher. The telephoto lens and portrait lens in the rear camera also had their own functions and characteristics, while the front camera might be relatively weak in this respect. In terms of functional positioning, the rear camera was more used to shoot various scenes such as landscapes and people. It could also achieve more complex functions such as zooming function brought by the telephoto lens, such as 2x non-destructive zooming under the dual-camera scheme, which could shoot clearer and higher-quality blockbusters. The front camera was more used for selfies and other scenes. In addition, the resolution was also one of the influencing factors. The front and rear cameras with different resolution would have different imaging effects. For example, the 48-million-resolution rear camera would be different from the low-resolution front camera in terms of long-range shooting and details. However, in daily use, even if the front camera had a relatively low resolution, it could still meet the needs of selfies. Moreover, in order to protect privacy, people might cover the front camera with a sticker to directly physically isolate their photo authority, but they rarely did this for the rear camera.

People in front of the camera automatically take pictures
According to the reference materials, some smart cameras had a human-shaped detection function. When a human figure was detected in front of the camera, some operations would be triggered. However, there was no mention of a camera that automatically took pictures of people. If you want to achieve the automatic photo function of the person in front of the camera, you may need a device with certain intelligent functions (such as human recognition, automatic photo function, etc.). For example, the Google Clips artificial intelligence camera could recognize specific faces (in theory, it was possible to detect and take photos through similar technological modifications). It automatically selected scenes, videos, and saved through artificial intelligence technology, but this was not a feature specifically for automatic photography. Some home surveillance cameras, such as Huawei Smart Choice, had built-in AI recognition technology that could distinguish between humans and pets. However, it was mainly used for monitoring to reduce false alarms rather than taking photos automatically. Therefore, there was no equipment that was specially used to automatically take pictures of people in front of the camera. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Use the front camera to take pictures of big and small faces
There may be the following reasons for using the front camera to take photos: 1. Self-portrait image: When the phone's front camera takes a selfie, it presents a mirror image. This mirror selfie itself may have some distortion, resulting in the visual effect of a large and small face. 2. The problem with the selfie angle: When the angle is not suitable, the size of the face will be shown. Only when the angle is suitable can the normal face shape be shown. 3. Unstable phone: If the phone is not held firmly when taking a photo, the photo taken under unstable conditions will appear askew or blurry, which may also lead to the visual effect of a big or small face. 4. Asymmetrical face: In addition to factors related to photography, the face itself will also lead to the appearance of a big or small face when taking photos with the front camera. For example, the development of the mandible was not symmetrical, the cheekbones were not symmetrical, and the facial soft tissues were not symmetrical. Acquired habitual reasons, such as eating on one side for a long time, the muscles on this side will be more developed, the side that is not used often will shrink, and it will also aggravate the size of the face; Sleeping on the same side for a long time, the jaw may be displaced by the reaction force of the pillow; The pillow is too hard, which may also cause the jaw to be displaced; Tooth extraction or jaw injury in the past and habitually chewing on the side that is not injured, etc. will affect the facial soft tissue or bone symmetries. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Apple's front camera can't take pictures
This situation could be caused by poor contact with the front camera or a malfunction of the front camera. If it was still under the guarantee period, it could go to the after-sales service to seek the guarantee treatment; if it was not under the guarantee period, it could go to the outside repair market to find a repair shop to repair it. After explaining the phenomenon, if it was detected that the contact was bad, the camera would be unplugged and plugged back in to solve the problem; if the camera was damaged, the camera would be replaced. In addition, if the iPhone 7 is turned on normally, but the front camera is turned on with a "black screen"(it is normal to turn on the main camera), it may be caused by the motherboards, such as J4503: The 1.8V power supply line of the 3-pin is open.(If this situation is detected, the filter component connected to it can be detected. If the IL2901 is damaged, the fault can be eliminated by short-circuiting the two ends of the IL2901.) <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The front end calls the camera to detect faces and take pictures.
The front-end calling the camera to detect faces and take pictures can be achieved in the following ways: - In the current version of the game, you can use <video>tags and the Media Devices API to access the camera, while the back end is responsible for processing the video stream and executing the Face Recognition algorithm. Specifically, the front-end can use the MediaDevices. getUser Media () API to capture the user's video stream, and then periodically capture image frames from the video stream. After capturing the image frames, the captured image frames can be sent to the back-end service using the javelin's fetch API or XMTpRequest. The image may need to be converted into a Base64-encrypted string to be sent in an ftp request. - In an iPhone application, it can be implemented using native Swift code, Core QL, and ARKit. Create an iPhone project with a single-view application, import ARKitand instantiate an ARSCNView, which will automatically render the real-time video feed from the device's camera into the background and match the real-world motion of the device. Start a session with ARFaceTrackingConfig (for iPhone X, Xs, and Xr's front-facing TrueDepth camera), which can detect the user's face based on the device's front-facing camera. You can also extend the View Controller and use the scene delegation ARSCNView Mandate to perform face detection and other operations. In addition, you can also use tracking.js to detect the face in the video stream at the front end. After detecting the face, you can take a photo and upload it to the back end to realize the face login function. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Can the camera take pictures?
The camera could take pictures. Early cameras required the use of film (videotape) for recording. Now, with the invention of digital cameras, images could be stored directly in flash memory. Newer cameras could also store images directly in the hard disk of the body. Not only could they record in motion, but they could also shoot still, so there was no need to carry a digital camera at the same time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Using the camera to take pictures
Here are some key points to take pictures with the camera: ###1. Device Selection (Take the phone camera as an example) 1. ** Number of lenses and telephoto plan ** - When choosing a phone to take photos, the number of lenses (three or four shots) was not the only factor that determined the effect of the photo. For example, some brands moved from four cameras to three cameras. As for the telephoto lens, it was limited by the size of the phone. The large base, high resolution, long focal length, and large aperture could not exist at the same time on the phone telephoto lens. Nowadays, many mobile phones relied on the "main camera + algorithm" to ensure the clarity within a certain focal length range. For example, some models of Huawei and Vivo could meet the needs of a variety of focal lengths through a combination of reasonable lens configuration and algorithm. 2. ** Key components of the imaging system ** - When using the phone's camera to take a photo, the lens would first project the scene on the image sensor. At the same time, the image processor (Isp) would calculate the appropriate parameters through light measurement and ranging and instruct the lens to focus. ###2. Shooting Techniques 1. ** Focus * - The phone had an autofocus function, but sometimes manual focus was more suitable. When taking landscape photos, if you want to highlight a certain scenic spot, touch the screen to select the scenic spot as the focus (a yellow mark will appear on the screen). When the shutter is pressed, the focus will accurately fall on the area. 2. ** Picture composition ** - He could draw on many composition techniques, such as the method of thirds. Imagine four lines (two running across the top and bottom of the picture, and two running through the sides) dividing the picture into nine equal areas. The focus of the picture is usually at the intersection of these areas. 3. ** Special Mode ** - If the scenery in front of you is vast and the wide-angle lens is difficult to see, you can use the panoramic mode. After turning on the panoramic mode, click the shutter button from the starting point, and then slowly move to the end point to take a panoramic photo. - Using the time of dawn and dusk (one hour after sunrise and one hour before sunset) to shoot, the color temperature of the light during this period was relatively low, and the brightness and color changes were rapid. It could create rich light and shadow effects and soft light, which was suitable for taking landscape photos. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
