Abstract:
A method and system are provided for image scaling including low resolution text areas. The method may include: determining one or more areas of text in an image to be scaled; scaling the one or more areas of text using two or more scaling algorithms to a required resolution to acquire two or more scaled versions of the text area; selecting the clearest text in a text area from two or more scaled versions of the text area; scaling the overall image to the required resolution; and merging the scaled overall image with the selected scaled version of each text area.
