Writing recording method, mobile terminal and computer readable medium

Abstract

The invention discloses a writing recording method, a mobile terminal and a computer readable medium. The mobile terminal includes a mounting surface, a camera mounted on the mounting surface and a first laser transmitter, wherein the first laser transmitter is disposed on the edge of one side of the mounting surface, the camera and the first laser transmitter are disposed at an interval, and the camera is arranged on the side, away from the edge of the side, of the first laser transmitter; the mobile terminal further comprises a writing recording program which conducts processing by combining the camera and the first laser transmitter, and the operation of the writing recording program comprises the following steps of controlling the first laser transmitter to emit a laser and controlling the camera to collect an image when an instruction for starting a writing recording function is received; obtaining laser spots, reflected by a pen tip, in the image; obtaining actual positions of the pen tip according to positions of the obtained laser spots; connecting points of multiple continuous actual positions into a line and smoothing the line, and obtaining a drawing graph. According to the writing recording method, the mobile terminal and the computer readable medium, an effect of recording handwriting content of a user through the mobile terminal can be achieved.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a writing and recording method, a mobile terminal and a computer-readable medium. Background technique [0002] Currently, with the development of mobile smart electronic devices, users are increasingly inseparable from mobile terminals, and users hope to handle everything through mobile terminals. [0003] Some user groups need to use a pen for office work, such as designers and students. [0004] However, since the screen of the mobile terminal is very small compared to paper of A4 size, the working space for writing or drawing with a pen on the screen of the mobile terminal is too small, which is not conducive to office work; and due to the hardness of the glass of the display screen of the mobile terminal Extremely high, resulting in a very poor tactile feel for writing or drawing on the screen. Therefore, the above-mentioned situation makes it difficult for the user to use ...

Problems solved by technology

[0004] However, since the screen of the mobile terminal is very small compared to paper of A4 size, the working space for writing or drawing with a pen on the screen of the mobile terminal is too small, which is not conducive to office work; and due to the hardness of the glass of the display screen of the mobile terminal Extremely high, resulting in a very poor tactile feel for writing or drawing on the screen

Therefore, the above situation makes it difficult for users to use mobile terminals for handwriting office work, so it is difficult to save real-time handwriting content from users through mobile terminals, such as various drawing designs, lecture notes, etc.
