1. A method of processing an image, the method comprising: generating a plurality of grayscale images from a multi-channel image, the plurality of grayscale images comprising a first grayscale image and a second grayscale image, the first grayscale image distinct from the second grayscale image; identifying at least one text region in the plurality of grayscale images; determining text region information from the at least one text region; and generating text information of the multi-channel image based on the text region information.

The method of claim 1 , wherein generating the text information of the multi-channel image includes, if two or more text regions including a first text region and a second text region of the at least one text region are identified in two or more of the plurality of grayscale images, merging first text region information from the first text region and second text region information from the second text region.
