[0002] A magnifying glass is a simple visual optical device used to observe tiny details of an object. It is a converging lens with a focal length much smaller than the clear vision distance of the eye. A handheld magnifying glass usually consists of a convex lens, a frame, and a handle. When using it, place the object close to the lens (within the focal length) to see an upright and enlarged virtual image, which helps to distinguish details. It is often used to view specimens, drawings, negatives, photos, film copies, etc. At the same time, magnifying glasses are also common props in children's science and education toys.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0023] The following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] First embodiment:
[0025] The utility model is a handheld electronic magnifying glass. Figure 1-4 , including a main body 1, a handle 2, an image acquisition device 3 and an image display device 4, the handle 2 is installed on the main body 1, a groove 5 is provided at the rear end of the main body 1, the image acquisition device 3 is arranged in the groove 5, and a first light shield 6 is also provided at the edge of the groove 5, the first light shield 6 is used to reduce the influence of external ambient light on the image acquisition of the image acquisition device 3, the image display device 4 is arranged at the front end of the main body 1, the image display device 4 is electrically connected to the image acquisition device 3, and is used to display the image information acquired by the image acquisition device 3. During use, the image of the target position is acquired by the image acquisition device 3, and the image of the target position is processed by the image acquisition device 3 through a corresponding algorithm program or software program to obtain an enlarged image, and the enlarged image is displayed through the image display device 4. In this embodiment, the optical imaging of the traditional magnifying glass is replaced by an electronic imaging method, which not only makes the enlarged image not have the situation of local blur and bending of the image edge, but also can adjust the image magnification through the algorithm program or software program.
[0026] In this embodiment, a fill light 7 is provided in the groove 5 , and the fill light 7 is arranged around the image acquisition device 3 . The fill light 7 increases the brightness of the surrounding ring, so that the image of the image display device 4 is clearer.
