24. A method of processing an image, the method comprising: generating first grayscale image data using first channel data of multi-channel image data associated with a multi-channel image; generating second grayscale image data using second channel data of the multi-channel image data, the first grayscale image data distinct from the second grayscale image data; identifying first text region data in the first grayscale image data; identifying second text region data in the second grayscale image data; determining first text region information from the first text region data and second text region information from the second text region data; and generating text information of the multi-channel image based on the first text region information and the second text region information.
