Text processing method for a digital camera

摘要

Embodiments disclose a technique to recognize text in a current frame of an image in a view finder of a digital camera. In accordance with the technique, text at a marker (e.g. a cursor or cross hairs) associated with the view finder is recognized and a lookup is performed based on the recognized text. Advantageously, the lookup yields useful information e.g. a translation of a recognized word that is displayed in the viewfinder adjacent to the text. The current frame is not captured by a user. As the user moves the camera to position a new word at the marker, the view finder is updated to provide lookup results associated with the new word. Lookups may be performed of a bilingual dictionary, a monolingual dictionary, a reference book, a travel guide, etc. Embodiments of the invention also cover digital cameras or mobile devices that implement the aforementioned technique.

主权项

1. A method for a mobile device equipped with a digital camera, the method comprising:
detecting a plurality of frames by the mobile device; detecting text in a current frame of the detected plurality of frames for an image associated with a viewfinder of the mobile device; performing recognition of the detected text which produces a recognized text without freezing the current frame on the viewfinder; performing a linguistic morphology analysis of the recognized text, wherein the linguistic morphology analysis includes obtaining one or more base dictionary forms for one or more words of the recognized text; performing a lookup operation based on the one or more base dictionary forms wherein the lookup operation returns a plurality of translations of the base dictionary form wherein the plurality of the translations is limited based upon at least one of the following factors:
frequency of the translations of the base dictionary form used, and additional context information associated with one or more of the base dictionary forms; and displaying a translation result of the lookup operation in the viewfinder.
