The story happened today. I was changing my computer architecture assignment. I found that many students wrote my assignment on paper and made photos into electronic copies. Some people made it word or even PDF, A lazy student directly uploads n photos. These photos are a headache for me because I have to download one and sort them by myself, and some photos are even blurred. I hate such assignments, but I understand that they do this because I am also a student. I know that homework on paper is sometimes much faster than on a computer, especially jobs that require drawing at any time, and not everyone has a scanner. However, even with a scanner, it is difficult to scan photos, edit photos, and edit Word documents. I usually use a scanner, but I seldom use it, which is mainly too troublesome. I suddenly thought that this is a good product demand, a real good idea. If you have read the article written by Paul, you can clearly identify what a good idea is. The foundation of a good idea is a real demand. Well, back to the truth, I am thinking that if I can develop an application and directly turn my homework on paper into a PDF document, there must be a market, at least a market for students. Before I thought about how to do this application, I found an app named turboscan on my mobile phone 20 minutes later. I saw its promotional images and immediately understood that this was what I wanted (the text was really good), so I did not hesitate to buy it, with 1.99 knives.
The main function of this app is to replace the scanner. As long as the iPhone is used to take photos of paper, it will automatically crop the paper according to the size of A4 paper (2 ), in addition, the font is clear by adjusting the contrast, and then saving the PDF to Dropbox or directly sending an email to someone else or yourself. I tried it and it really worked very well. In the review column of the app, Someone commented that the scanner is not needed if the app is used. I admit that at first I didn't expect to implement this function on the mobile phone, but after seeing this product, I realized that only the mobile phone can implement this function, and the camera won't work, currently, few cameras have smart systems. Laptops are smart enough and most of them have cameras, but the size and weight are a big problem. It is like using a bench as a ruler to draw a picture on a computer. I finally understand that the size of smart devices is very important. The size changes, especially smaller ones, can produce breakthrough applications.
Now you have a scanner. If you have a smartphone, it is more convenient and only costs $1.99.
