Is the scan clear or the photo clear?Generally speaking, the resolution of the scanned documents was higher. Scanning was an electronic version of the original picture, and its clarity was not affected by external factors. The clarity of the photo depended on the phone's resolution, photo technique, lighting, background, hand shake, and other external factors, so the scanned image was relatively clearer.

The photo is clear, but the selfie is not clearIf the photo is clear but the selfie is unclear, there may be the following reasons and solutions:
* * 1. The features of the phone's front camera **
1. * * Focus problem **
- If the phone's front camera supported a fixed focal length, it could only shoot clearly at a specific distance. It was generally recommended to shoot within the range of 25 - 50 cm. If autofocus is supported, the focus distance can be adjusted to capture clear near or far objects within the effective range. To check if the phone's front camera supports focusing, you can open the service app → My → My Device → Check the device parameters, or open the phone's official website → specifications → main parameters → front camera. The official website marks "autofocus","OIS","AFF" to indicate that the focus function is supported. Mark "fixed focal length","FF" or no mark, the front camera does not support the focus function.
2. * * Cleaning problem with the camera **
- Make sure that the front camera surface is free of dirt, obstructions, and film. If there is dirt or obstruction, you can use a clean and soft cloth (such as glasses cloth) to clean the front camera area before taking another photo. If there is a film that blocks the lens, it is recommended to cancel the protective film for a better photo experience.
* * 2. Shooting environment **
1. * * Light factor **
- If he took a selfie in the dark, it would easily cause the picture to be unclear. It is recommended to turn on the flash or take photos in a well-lit environment.
2. * * Background interference **
- If the background is too messy during selfies, it may affect the accuracy of the focus or make the subject not stand out enough. Try to choose a simple background, such as a pure color background.
* * 3. Shooting operations **
1. * * Focus Operation **
- Make sure that the camera is focused and click to take a picture. Wait until the focus frame disappears before taking a picture. Before the focus frame disappears, it means that the camera is still focusing. Otherwise, it may cause blurry pictures.
2. * * The camera grayed out **
- If there is dust in the front camera lens, please back up the data in advance (third-party applications such as QQ and WeChat need to be backed up separately) and go to the nearest Huawei customer service center to clean it up (if it is a Huawei phone, other brands of mobile phones can go to the corresponding after-sales center).
* * 4. Phone settings **
- He could open the phone's settings, click on the camera option, turn on the automatic HPR button, and then choose the format to enter. He could check the high efficiency to help improve the clarity of the selfie.

Professional camera photo file formatThe commonly used photo file format for professional cameras were JPEG, TIFF, RAW, and so on.
JPEG was a loss-compression format that reduced the storage size by removing excess data. The compression ratio was between 10:1 and 40:1. Its advantage was that it could save a lot of memory card space, increase the number of pictures taken, speed up photo storage and continuous shooting speed, and was suitable for daily photography. It was processed by the image processor inside the camera and could be directly produced. When there was no need to do very detailed post-processing on the image, it could basically meet most of the needs. Moreover, due to the small space occupied and the fast upload and download speed, it was widely used on the Internet.
TIFF was a commonly used industry standard format, often used in situations involving printing. It was a non-distorting compression format (up to 2 - 3 times compression ratio). Some repetitive information in the file was recorded in a special way. The file could be completely restored, and the original image color and level could be maintained. The image quality was good and the compatibility was good, but it took up a lot of space. When you save the processed photo as a TIFF with PS, you can save the Alpha channel, layer, spot color channel, and other information.
The RAW image was not a directly edited image format. Strictly speaking, it was a record of the raw data when the camera's CCD-or CMOS-converted the optical signal into an electrical signal. It simply stored the image data that had not been processed inside the digital camera. It was neither processed nor compressed. For a camera with a 5-million-pel resolution, a RAW file saved 5 million points of light sensitivity data, which was a large file. However, it saved the original image coding data, which was very beneficial for the photographer's post-processing, such as color space, sharpening value, white balance, contrast, noise reduction and other operations that could be controlled and adjusted on the computer. When taking photos in the RAW format, other than the settings of the camera such as the shutter, aperture, and focal length, the other settings of the camera basically had no effect on the RAW file.

Linuxc language to clear the txt fileThere are two ways to clear the txt-file in C language under Linux2:
1. Use the fopen() function: fopen is the standard library function of the C language. It uses the "w" mode to open the file. If the file name is the same as an existing file, the contents of the existing file will be deleted and the file will be treated as a new empty file. The sample code is as follows:
```c
#include <stdio.h>
#include <stdlib.h>
int main() {
FILE * fp;
fp = fopen ("file.txt", "w");
fclose(fp);
return(0);
}
```
2. Use the fintercept () function: This is the system call function used to set the file size. To empty the file, set its length to 0. Remember to close the file description after using it. The sample code is as follows:
```c
#include <stdio.h>
#include <unistd.h>
int main() {
int fd = open("file.txt", O_RDWR);
ftruncate(fd, 0);
close(fd);
return 0;
}
```

In addition, for the convenience of the masses, the public security household administration window of the Wuling District Government Affairs Center also had a "cloakroom", which was equipped with a complete set of clothing and dressing items, such as combs, hair gel, hair clips, hair ropes, makeup removal cotton, etc., for the citizens who came to apply for ID cards to tidy up their appearance before filming. If you're not satisfied with the photos, you can check them on the computer after taking them. If you're not satisfied, you can take them again.

Intermediary card, photo uploadIf the intermediary took photos and uploaded relevant information when applying for the card, there was a certain risk. Some unscrupulous agents might cheat information and collect all personal information, including identity information, work, education, family, relatives and friends, etc., for sale. If the intermediary claimed to help apply for a credit card and asked for card information (such as the expiration date, the last three security verification codes on the back, the transaction password, etc.), they might use this information to transfer funds online. There were also unscrupulous agents who asked for scanned ID cards or remote Face Recognition, original savings cards, etc. in the name of card application. It might be to swindle the savings card and then sell it or carry out illegal activities such as money laundering.
However, when a formal intermediary handles business, they will protect the customer's information security according to the prescribed procedures and bear certain legal responsibilities. However, when selecting an intermediary, they still need to carefully evaluate their reputation and service level, clearly inform the other party of the purpose and scope of information use and ensure information security.
