An electronic magnifying glass system

Abstract

The invention discloses an electronic magnifying glass system, which comprises a signal input module, a control module, a signal processing module, an image adjustment execution module, and an image display module; the signal input module is connected with the control module, the signal processing module, and the image adjustment execution module, and the control module It is also connected with the signal processing module and the image display module, and the signal processing module is also connected with the image adjustment execution module; the signal input module includes a coaxial focusing lens group, a zoom lens group, a first beam splitter, an image sensor, and a setting The light energy sensor on the side of the first beam splitter; the light passes through the focusing lens group and the zoom lens group and is divided into the first transmitted light and the first reflected light by the first beam splitter, and the image sensor is set to receive the first transmitted light , the light energy sensor is set to receive the first reflected light. The invention is easy to operate, realizes automatic light metering, automatic light compensation, automatic zoom and stepless magnification, and improves reading comfort.

Description

technical field [0001] The invention relates to the field of auxiliary reading, in particular to an electronic magnifying glass system. Background technique [0002] In reality, there are a large number of visually impaired people. For them, the characters on information media such as many books and newspapers around them are too small to read clearly. Some visual impairments cannot be solved by wearing reading glasses, and the font must be enlarged. The main solution at present is an optical magnifying glass. [0003] The essence of optical magnifying glass is a convex lens, which realizes magnification through simple optical principles, including: spherical lens and aspheric lens. Because of its portability and low cost, it is widely used. But it has at least the following deficiencies: First, due to the pure optical magnification of the spherical lens, there is inevitably obvious distortion at the edge of the lens, which will cause dizziness when reading for a long tim...

AI Technical Summary

Problems solved by technology

But it has at least the following deficiencies: First, due to the pure optical magnification of the spherical lens, there is inevitably obvious distortion at the edge of the lens, which will cause dizziness when reading for a long time. Vomit, etc.; aspheric lenses can resolve distortion, but not completely, and are expensive

And because the brightness of the pure optical magnifying glass itself is not high, it will cause great trouble to read
