Scanning pen device and method capable of adjusting shooting font size

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...
