Handheld reader and reading control method and device thereof

Abstract

The invention discloses a handheld reader and a reading control method and device thereof, and the method comprises the steps: responding to a set reading event, obtaining a current reading mode of the reader; according to the current reading mode, controlling a matched optical filter to move to a filtering action position of a camera module of the reader, and starting the camera module to acquirean image; according to the current reading mode, identifying reading content matched with the current reading mode from the image; and executing a setting operation corresponding to the current reading mode for the reading content.

Description

technical field [0001] The invention relates to the technical field of digital equipment, in particular to a reading control method of a hand-held reader, a reading control device of the hand-held reader, and a hand-held reader. Background technique [0002] Currently, handheld readers on the market include point reading pens, scanning pens, and the like. The point reading pen is used in conjunction with the audio book. The carbon ink color invisible code is printed on the paper of the audio book. The image style of the invisible code printed at different positions of the audio book is different, and each image style has a unique number. When the point reading pen points to different positions, read the invisible code at the corresponding position, and determine the number of the invisible code according to the image style of the read invisible code, so as to find it in the file library stored by the point reading pen according to the number The matching sound file is playe...

Problems solved by technology

This shows that for the existing point reading pen, when it is expected to be expanded to be used as a scanning pen, the scanning pen can only read black text content, but for colored text, background-colored text, textured text, etc. The recognition ability of text, etc. is poor, or even completely unrecognizable, and the recognition rate equivalent to a single-function scanning pen cannot be obtained.

For the scanning pen of the prior art, it uses a visible light filter to collect text images. Therefore, only visible light can reach the image sensor for imaging, but because the invisible code layer is an infrared layer, it cannot reflect visible light. Therefore, Existing scanning pens cannot read invisible codes at all, and of course they cannot obtain the recognition rate equivalent to a single-function point-reading pen
