Excuse me, what is a scanned photo? Do the relevant documents for taking photos with mobile phones meet the requirements?

The scanned photo is the picture format of the examinee's certificate.

Generally speaking, the picture format of the certificate is scanned by a scanner.

However, digital products are more common now. You can get certificate pictures in picture format through digital cameras and mobile phones. Usually, they are uploaded in JPG format. Postgraduate certificate pictures have certain format requirements, including the pixel of the picture and the size of the picture itself, which generally requires several hundred kb, not a big picture.

If the pixel of the mobile phone is relatively high and the photos you can see on the computer are relatively clear, that is also possible; If the pixel of the mobile phone is very common, and the handwriting can't be seen clearly, you can't take pictures with the mobile phone. You can find a digital camera to take pictures.

Expand the resolution of data photos.

① The optimal resolution of the image =2× the number of screen lines.

② scan resolution =N× the optimal resolution of the image (where n represents the magnification, for example, the number of lines of the manuscript is 150LPI, and the scan resolution during scanning should be set to 2× 2×150 = 600 dpi) PPI = n× dpi = n× dpi.

The best zoom ratio of photos

Sometimes we use zoom scanning. At this time, we should pay attention to a problem-scanning, zoom ratio × scan resolution should not be greater than "the maximum scan resolution of the scanner".

Attached:

1, the worse the paper quality, the lower the screen resolution;

2. Image output equipment is generally composed of laser spots above 10× 10, that is, DPI must be greater than 10 to 20 times LPI, and output resolution (output accuracy -DPI) = number of output lines × 16).
