33. An apparatus comprising: at least one image converter configured to generate first grayscale image data using first channel data of multi-channel image data associated with a multi-channel image, the at least one image converter further configured to generate 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; a first text region detector configured to identify first text region data in the first grayscale image data and to determine first text region information from the first text region data; a second text region detector configured to identify second text region data in the second grayscale image data and to determine second text region information from the second text region data; and a merging unit configured to generate text information of the multi-channel image based on the first text region information and the second text region information.
