Electronic magnifying lens system

Abstract

Disclosed in the invention is an electronic magnifying lens system comprising 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; the control module is 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 consists of a focusing lens group, a zoom lens group, a first beam splitter, an image sensor, and a light energy sensor arranged at one side of the first beam splitter. Light passes through the focusing lens group and the zoom lens group and is split into first transmission light and second reflection light by the first beam splitter; the image sensor is configured to receive the first transmission light; and the light energy sensor is configured to receive the first reflection light. According to the invention, the system can be operated conveniently; automatic light measurement, automatic illumination compensation, automatic focus changing, and non-polar zooming are realized; and a reading comfortable level is improved.

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...

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
