Definitions

  • the invention relates to a device for reading and outputting texts and / or images, in particular a reading device for people with visual impairments, comprising a stand for setting up the device, a detection unit for detecting texts and / or images with a detection surface, a processing unit for processing the acquired texts and / or images and an output unit, in particular audio unit, for outputting the processed texts and / or images.
  • readers are used to enable people, despite their visual impairment, to capture texts and / or images, for example by recognizing and at least partially reading the text or images.
  • An already known reading device is substantially cuboid.
  • the text to be recorded for example, be placed in the form of an open book to its capture.
  • the opened book with the text to be recorded is illuminated from above via a fold-out swivel arm, and an image of the text is obtained by means of a camera with swivel arm.
  • the reader processes the data captured by the camera and then reads the recognized text to a corresponding user.
  • One of the disadvantages of this device is that the device requires a lot of space, especially footprint on a desk.
  • a further disadvantage is that the detection by means of the camera via the swivel arm is faulty, since stray light, such as ambient light, shadows, etc., complicates detection of the contents of the unfolded book, especially if the book has a thick fold.
  • a reading device has become known, which is also cuboidal.
  • the reader has a detection surface on which books, magazines or magazines can be placed to detect their contents. These can be fixed by means of a flap on the detection surface.

  • One of the other disadvantages of this device is that it also requires a lot of space, for example on a desk.
  • books with a thin fold can be reliably detected, since in books with thick fold, the pages in the area of the fold are strongly curved and thus a detection is difficult.
  • Another known reading device is also designed essentially cuboid, with a camera is mounted fold-out. In this way, the reader can partially capture a book placed under the camera.
  • the disadvantage here again is that ambient light makes capturing text and images more difficult. Even books with thick folds are difficult to capture.
  • This reading device includes a fold-out stand and a pull-out support arm on which a camera is arranged. If, for example, the device is set up on a desk and the support arm extended, the camera can use it to capture a magazine, a book or the like, which is also arranged on the desk and next to the reading device, and after appropriate recognition and processing texts and / or images read out.
  • a disadvantage that on the one hand due to the rather large distance between the camera and images to be captured and / or texts as well as due to environmental influences such as lighting, etc., a capture of the text and / or images is considerably more difficult. Even books with thick folds are difficult to capture.
  • An object of the present invention is therefore to provide a device which simplifies detection of texts and / or images. Moreover, it is an object of the present invention to provide a device which is simple in construction and inexpensive to produce. Moreover, it is an object of the present invention that contents of books with thick folds can be detected quickly and reliably.

  • This makes it possible, on the one hand, that the content of books, magazines or the like can be detected reliably with a thick seam, since the book must be opened less widely, so that the pages of the book are less strongly bent and can lie flat on the detection surface ,
  • the content of the page can be better detected.
  • Another advantage of regarding the footprint oblique detection surface is that so that the footprint can be made smaller overall, which is advantageous for the required space for the device on the desk, as it can be made smaller.

  • a covering and holding device for covering the detection surface is arranged.
  • the covering and holding device on the one hand, for example, the part of a book, which is arranged on the detection surface for detecting, can be fixed in its position.
  • the covering and holding device suppresses disturbing ambient or scattered light, so that a substantially defined environment is provided for capturing contents; this further improves the reliability in capturing content from books, magazines, etc.
  • the cover and holding device in a closed state at least partially adjustable in terms of their distance from the detection surface.
  • the flexibility of the device is further increased, so that books, magazines with different folding thicknesses by means of Reader can be detected and read.
  • the reliability in recognizing contents of books, magazines with different thicknesses is ensured by an adjustability of the covering and holding device, since thus even with very different thicknesses ambient and / or scattered light, which would complicate detection, can be hidden more reliably ,
  • the cameras have a resolution of at least two megapixels, in particular of at least five megapixels, preferably at least eight megapixels. In this way, a sufficient resolution of the cameras for capturing content with small font size or of small format images across the capture area is ensured.
  • the cameras have lenses with opening angles of at least 90 °, in particular of at least 120 °, preferably at least 140 °.
