摘要

It provides an apparatus and method for detecting telephone number information from the digital broadcasting in a digital broadcast receiving terminal. Device for detecting telephone number information from the digital broadcasting according to the present invention, the digital broadcast receiver for receiving digital broadcasting data, the one of the received digital broadcasting data I frame scan (scan) scan section and, from the scanned I frame to in area to be considered as containing the number information of the display area of ​​the digital broadcasting reception terminal region ROI (region of interest: region of interest) to detect, binarizing the detected ROI, removing a non-text region from the binarized ROI and , letters and extraction unit for dividing the ROI is a non-text region is removed by at least one blob letters open areas consisting of the areas of lettering region or a character region including the (blob) that can be recognized as a number, letter or symbol, extracting only of the analyzes along the segmented character region or a character column region on the predetermined condition analyzing character region or a character column region number area, and recognizes the number data over a weighted manner prescribed blobs contained in the extracted numeral region and the telephone number extraction unit performs the recognition operation for, and using the recognized numeral data to combine at least one telephone number, determine whether the character column region or the character region is the number area divided by the character extraction section and the number area the case includes a control unit for controlling the extracting unit so as to perform the telephone number recognition operation. ; Digital broadcast, extracts the numeric data, phone number combination
