Head-worn optoelectronic automatic focusing visual aid

Abstract

The invention discloses a head-worn optoelectronic automatic focusing visual aid. The visual aid comprises a micro optical wide-angle zoom lens, an image sensor, an electronic module of an electronic full-time automatic focusing image processing system, a micro display module, a head-worn balance weight mechanism, a digital controller and the like. Automatically acquired continuous video images or E-book data are displayed in a specific mode through a micro display; a balance weight structure adopted by the device can effectively transfer the weight of the visual aid in front of eyes to two side parts of the head so as to avoid pressure caused by the visual aid on the forehead and the nose bridge; meanwhile, the automatic full-time electronic focusing micro optical zoom wide-angle pick-up lens and the micro display module are integrated on a head-worn structure so as to meet human engineering characteristics and biological vision habits, assist in long sight and assist in short sight; and the current E-book reading tool is embedded into the visual aid so that a person not only can see the scene before the eyes, but also can read E-journal by using the visual aid and the like.

Description

technical field [0001] The invention is applicable to the field of vision aids, etc., and is specifically a head-mounted optical electronic digital self-zooming head-mounted vision aid. Background of the invention [0002] At present, there are three main types of vision aids on the market, one is optical vision aids, the other is electronic vision aids, and the other is electronic eye automatic zoom vision aids. Among them, optical vision aids can only be used to assist hyperopia or myopia due to the relatively small range of focal length changes; electronic vision aids mainly use large-size displays as display terminals placed on the desktop in front of the user, combined with a mobile camera module, In order to assist vision, this device cannot be moved at will and is not portable; [0003] As for the third type of electronic eye self-zooming vision aids, there is currently an analog camera module that uses optical zoom (zoom) as the main but no auto-focus function to as...

Problems solved by technology

Among them, optical vision aids can only be used to assist hyperopia or myopia due to the relatively small range of focal length changes; electronic vision aids mainly use large-size displays as display terminals placed on the desktop in front of the user, combined with a mobile camera module, In order to assist vision, this device cannot be moved at will and is not portable;

[0003] As for the third type of electronic eye self-zooming vision aids, there is currently an analog camera module that uses optical zoom (zoom) as the main but no auto-focus function to assist hyperopia, and has low definition; The MOS camera module with multi-fold focusing function mainly has limited hyperopia assistance, and mainly assists myopia; the wide-angle function is limited, and the field of view is small; and it is integrated with a micro-display. figure 1 ) or the bridge of the nose (such as figure 2 ) is worn on the head for support and placed in front of the eyes. Due to the large weight and volume, it will cause obvious discomfort to the user's forehead or bridge of the nose, and it is easy to restrict the brain's thinking. It is not suitable for long-term wear
