Abstract

The invention discloses a digital scanning and amplifying system, which comprises an input module, a control module, a conversion module, an execution module and a display module. The input module isrespectively connected with the control module, the conversion module and the execution module. The control module is also connected with the conversion module and the display module respectively. Theconversion module is also connected with the data of the execution module. The input module includes a variable lens, an electrodeless magnifier, a semitransparent mirror and an imaging sensor arranged on the first optical axis and arranged in sequence, and a light source, a condenser and a photoreceptor arranged on the second optical axis and arranged in sequence. The semi-reflective mirror is located at the intersection point of the first optical axis and the second optical axis, and the position of the semi-reflective mirror on the second optical axis is between the condenser and the photoreceptor. An imaging sensor photographs and generates an imaging signal, and a photoreceptor detects and generates a light energy signal. The system realizes automatic focusing and infinitely zoomingmagnification of the auxiliary reading device, thereby facilitating the operation of the reader and improving the reading comfort.

Description

technical field [0001] The invention belongs to the field of optical related equipment, and in particular relates to a digital scanning and enlarging system. Background technique [0002] As people live longer, and for various other reasons, the number of visually impaired people is increasing. The words on many information media such as books and newspapers are too small for them to read clearly. Some vision impairments cannot even be resolved with reading glasses. Therefore, it is necessary to adopt other technical means to enlarge the font. [0003] Optical magnifying glass is one of the main technical means. Its essence is a convex lens, which achieves magnification through simple optical principles. There are two types of spherical lenses and aspheric lenses. Because optical magnifiers are easy to carry and low in cost, they are widely used. But it still has defects, and there are at least two shortcomings: one is that for spherical lenses, due to the principle of ...
