Abstract

The device includes a CCD camera for taking pictures of characters of various sizes and forms. The camera includes an automatic focussing facility. The signals obtained are digitised and fed to a microcomputer which identifies the characters. The digital signals are converted into acoustic signals which are provided to either a loudspeaker or headphones.

Description

Die Erfindung betrifft eine Anordnung von Hardware zum Erzeugen von Tonsignalen (Sprache) aus beliebig großen und verschieden weit entfernten Schriftzeichen und Formen. The invention relates to an arrangement of hardware for generating audio signals (speech) from any size and different distant characters and shapes.

Dabei wird mit einer CCD-Kamera ein beliebiges Bild aufgenommen, die Daten werden ausgewertet und akustisch wiedergegeben. In this case, any image is taken with a CCD camera, the data are evaluated and reproduced acoustically. Das Gerät ist in erster Linie für sehbehinderte Personen gedacht, die zwar in der Lage sind, sich zu orientieren, aber nicht die Möglichkeit haben, Texte und Formen zu erkennnen, bzw. zu entziffern. The device is primarily intended for visually impaired persons who are indeed able to orient themselves, but do not have the opportunity to are recognizable text and shapes, or to decipher. Dies trifft besonders auf die Gruppe der sogenannten Makulopathien zu, bei denen nur die Netzhautmitte geschädigt ist, und die ca. 80% der sogenannten Zivilblinden stellen. This is especially true of the group known as maculopathy in which only the center of the retina is damaged, and represent the 80% of the so-called civil blind. Ein weiterer Anwendungskreis sind die Analphabeten. Another application circuit are illiterate.

Der Anwender kann mit Hilfe der CCD-Kamera ein Objekt seiner Wahl digitalisieren. The user can digitize using the CCD camera, an object of their choice. Dieses Bild wird softwaregesteuert ausgewertet. This image is evaluated under software control. Der Microcomputer wandelt die digitalen Daten in akustische Signale um, die dann über Lautsprecher wiedergegeben werden. The microcomputer converts the digital data into acoustic signals which are then reproduced via loudspeakers.

Zur Zeit werden zur Unterstützung von sehschwachen Personen Geräte verwendet, die entweder mittels Scanner Texte einscannen und mit OCR- Software auswerten und als Sprache ausgeben. At present, devices are used to assist visually impaired persons who either scan using a scanner texts and evaluate them with OCR software and output as speech. Als zweite Möglichkeit wird ein Vergrößerungssystem verwendet, bei dem eine Textvorlage ausschnittsweise vergrößert wird. As a second possibility, a magnification system is used in which an original text is enlarged fragmentary. Die beiden Techniken benötigen eine Textvorlage, die eine bestimmte Größe nicht überschreiten darf. Both techniques require a text template, which can not exceed a certain size. Weiterhin muß bei der Textvorlage eine bestimmte Höhe eingehalten werden. Furthermore, in the original text a certain height must be maintained.

Bei dem vorliegenden Gerät ist eine Einhaltung bestimmter Maße nicht erforderlich, weiterhin können auch weiter entfernte Schriftzeichen und bekannte Formen erkannt und ausgewertet werden. In the present apparatus, a compliance with certain degree is not required to continue even more distant characters and known forms can be detected and evaluated. Zu erkennende Formen sind z. Be recognized forms z. B. Verkehrszeichen, Bus-Aufschriften, Fahrpläne an Haltestellen, Gesichter usw. Auch der Abstand von der Kamera zum Objekt kann mittels Autofocussystem ermittelt, und dem Träger des erfindungsgemäßen Gerätes akustisch mitgeteilt werden. B. traffic signs, markings bus, schedules at stops, faces, etc. Also, the distance from the camera to the object can be determined by means of autofocus system and be informed acoustically the carrier of the device according to the invention. Der Anwender ist somit in der Lage, sich in seiner Umwelt besser zu orientieren und informieren. The user is thus able to orient themselves better in its environment and inform.
