Problems solved by technology

[0003] The current scanning pen will be equipped with a pen tip that triggers the scanning event, and the width and height of the pen tip have been fixed, resulting in a certain limit to the text size of the scanned textbook. line of text, but the scanning pen can only recognize one line
If the tip of the pen is too small, it is easy to fail to scan the text completely when scanning reading materials with large fonts, resulting in failure of recognition

Embodiment 1

[0026] This embodiment provides a scanning pen device with adjustable font size for photographing, such as figure 1 , 2 As shown, it includes a scanning pen main body 1, a camera 2 is provided in the middle of the lower end of the scanning pen main body 1, and an MCU is arranged inside it; the scanning pen main body 1 also includes a font size adjustment command input module and a current output control module, Both the font size adjustment command input module and the current output control module are connected to the MCU; both sides of the lower end of the scanning pen body are provided with baffles 3, and the baffles 3 on both sides pass through the rotating structures on both sides respectively. It is connected to both sides of the lower end of the scanning pen main body 1, and can rotate around the rotating structure toward and away from the camera 2; inside the baffles 3 on both sides are provided with electromagnets, and the electromagnets are electrically connected in...

Embodiment 2

[0038] This embodiment provides a method for using the scanning pen device with adjustable font size described in Embodiment 1. The specific process is as follows:

[0039] In the MCU, the baffles on both sides can be rotated away from the camera at the same time in different positions to set the current size parameters required for the angle setting, and the baffles on both sides can be rotated in the direction close to the camera at the same time in different positions. Set the current size parameter required by the angle;

[0040] The user judges whether it is necessary to increase or reduce the font size of the shooting according to the font size of the reading material to be scanned, and if necessary, input an instruction to increase or reduce the shooting font size to the MCU through the font adjustment size instruction input module:

[0041] If it is necessary to increase the shooting font, after the MCU receives the instruction, according to the position of the baffle ...

Abstract

The invention discloses a scanning pen device and method capable of adjusting the shooting font size. The scanning pen device comprises a scanning pen body, a camera is arranged in the middle of the lower end of the scanning pen body, and an MCU is arranged in the scanning pen body; the scanning pen body further comprises a font size adjusting instruction input module and a current output control module, and the font size adjusting instruction input module and the current output control module are both connected to the MCU. Baffles are arranged on the two sides of the lower end of the scanning pen body, and the baffles on the two sides are connected to the two sides of the lower end of the scanning pen body through the rotating structures on the two sides and can rotate around the rotating structures in the direction close to or away from the camera. Electromagnets are arranged in the baffles on the two sides and electrically connected to the current output control module. According to the device and method, the shooting range of the camera of the scanning pen can be adjusted, so that the scanning requirements of reading materials with different font sizes are met, the problem that multiple lines of fonts are scanned at a time can be avoided, and it can be guaranteed that complete characters are obtained through scanning.

Description

technical field [0001] The invention relates to the technical field of scanning pens, in particular to a scanning pen device and method with adjustable font size for photographing. Background technique [0002] The scanning pen is a hand-held electronic device. The user can scan and input text or images by holding the scanning pen. Through the built-in optical character recognition (OCR) module, the text can be recognized, stored and edited. It is widely used in scenarios such as student learning and tourism translation. [0003] The current scanning pen will be equipped with a pen tip that triggers the scanning event, and the width and height of the pen tip have been fixed, resulting in a certain limit to the text size of the scanned textbook. line of text, but the scanning pen can only recognize one line. If the tip of the pen is too small, it is easy to fail to scan the text completely when scanning a reading material with a large font, resulting in failure of recogniti...
