Abstract

<P>PROBLEM TO BE SOLVED: To provide equipment for compensating eyesight for an amblyopic person, which does not give a sense of incongruity compared with the conventional spectacles type display. <P>SOLUTION: Sunglasses having shape freely selected in terms of design are used. An electronic display constituted to be easily attached/detached is attached inside the sunglasses, and an optical device which captures a video by a camera 7 attached separately in order to reflect an outside video, and enlarges and shows the video is attached thereto. Thus, a means enabling a person to read a volume or the like by enlarging and forming the image on a retina 8 through the electronic display which is attached inside the sunglasses and the optical device which enlarges the image. When reading the volume by using the electronic display and the camera concurrently, character information is captured by the camera 7 first, and digitally processed to enlarge the character to size fit to eyesight, and the character is successively scanned and digitally processed to be output, so that the character is successively displayed on the electronic display, whereby an enlarging reading system in a hand free state is provided for a weak-sighted person. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a field that can be used anytime and anywhere as a portable device when a person with poor vision is reading a book or looking at a distance. The present invention relates to a portable magnifier that uses an electronic display with a sunglass structure that allows the user to freely select a design that does not exist.

  As a vision improvement aid, an enlarged reading device using a camera and a personal computer is used, but these can be used in a fixed place, but they can not be used anytime and are limited in use. In particular, there is inconvenience that both hands cannot be used freely. When reading books such as books, looking at the blackboard at the same time in the classroom, etc., or viewing the image outside, sometimes you need many accessories such as using a loupe or using another camera There are many cases.

  Eyeglass-type displays are conventionally called head-mounted displays, face-mounted displays, eyewear, etc., and are widely used as portable electronic displays, and are used for portable DVD display devices, virtual reality display devices, and output display devices such as game machines. ing. In most cases, since the shape is uncomfortable compared to conventional glasses, the spread has been delayed. In particular, it is difficult to adapt to those with poor visual acuity, and in that case, the shape is particularly uncomfortable, which is an obstacle to popularization.

  When using an electronic display used for a mobile phone or the like outdoors, there is a problem in that it is difficult to see a display because the external luminance is too bright. In addition, it is difficult to see small characters such as newspapers in an aging society, and electronic displays that are displayed by scanning characters in the Shinkansen are convenient for providing passive information. However, it cannot be used for active information selection based on one's will, such as reading a book. Although it is possible to read a book through the Internet using an e-book or a mobile phone, it is difficult to use it for those with poor vision because of the small letters. When watching sports at a stadium or the like, binoculars are used because a distant image cannot be seen well, but both hands are blocked, which is inconvenient. With the advent of the information era, the use of video by cameras is increasing, and eyeglass-type small high-performance electronic displays are becoming widespread. However, these systems are required to be simplified and easy to operate.

Problems the invention is trying to solve

  The present invention has been made in view of the above-described circumstances, and makes it possible to use a sunglasses type that is not uncomfortable with conventional glasses in terms of design that is usually used for portable digital glasses. In addition, by using one portable small camera together with portable digital glasses, images such as books can be shot and stored with this camera in one shot, and character information is used from the stored images. The character size and display character reading / scanning speed can be set in accordance with the human eyesight, and character information such as a book is automatically output to an electronic display for easy reading. Once character information such as a book is stored, an external image can be freely photographed by a head-mounted camera simply by moving the head and can be output to an electronic display. Also, if the band to which the head camera is attached is removed and placed in a fixed place, it can be used as a fixed camera.

Means for solving the problem

In order to achieve the above object, the present invention is intended to be used anytime and anywhere, even for those with poor vision, and by attaching a commonly used sunglasses-type electronic display to a spectacle frame, It is possible to select a design with the same feeling as selecting normal sunglasses, and to provide a spectacle-type digital spectacle system that is less discomfort than conventional sunglasses. At the same time, by using a camera on the head at the same time, it is attached to one head to see the book at hand, hand operation to write characters etc. at hand, look at the blackboard, or look out It provides a system that can be switched by a single touch with a camera and used hands-free.

  The first solution is to attach a digital display with a structure that can be easily attached and detached to the spectacle frame of sunglasses whose design can be freely selected, according to the eye width of the person who uses it. An image is captured by a separately attached camera to display the image, and an optical device that can display the image in an enlarged manner is attached. Is displayed on an electronic display attached to the inside of the sunglasses.

The second solution is that one with poor vision, when reading a document, etc., if the text is too small to read, take a one-shot shot with a camera attached to the head using this document together with this device. Put it in the storage device in this device, set the size of the displayed characters and the scanning speed of the sequential display according to the eyesight of the person, and character information at the scanning speed preset for that person Can be read automatically and sequentially in a hands-free manner.
In addition, after taking a book with one shot, the output of the camera can be changed to direct input to the electronic display again with one shot, and external images can be directly monitored on the electronic display.

The invention's effect

  According to the present invention, when a person with poor vision reads a document or the like, it is possible to provide digital spectacles that are not uncomfortable as compared with ordinary spectacles in the appearance of sunglasses. At the same time, by wearing a camera on the head and using it together with the digital glasses, the displayed characters can be enlarged to the size of the characters according to visual acuity, and further scanned and displayed at a speed corresponding to the visual acuity, and the contents of the book Can be easily read with this digital glasses. And by changing the direction of the camera attached to the head that is used together with this digital glasses by one-shot operation, you can also see the external video you want to see, and you can enjoy multipurpose effects with one portable digital glasses It is possible to provide a very convenient system for those with poor vision.
