Abstract: An image reading apparatus, an image reading method and a program are provided for favorably correcting color misalignment in a sub-scanning direction of a read signal read by a plurality of line sensors without increasing a circuit scale or processing time. To accomplish this, the image reading apparatus sets, as a reference signal, the read signal that is output from one of the plurality of line sensors, and detects a correlation between the reference signal and each of a plurality of read signals output from line sensors other than the one of the plurality of line sensors of a plurality of lines that are displaced in predetermined line units from a line from which the reference signal is read, and selects a read signal having a high correlation with the reference signal as a read signal from the line of the reference signal.

Abstract: A cellular phone is provided with a media scanning capability. Scanner optics, an optional light source and related scanning circuitry is integrated within a cellular phone to enable image or text scanning, facsimile, text-to-speech conversion, and language translation. Position sensors provide position data as the scanner is manually moved, in one or more passes across the scanned media, to enable a bit-mapped image of the strip to be created in a data buffer. Image data from the strips is processed to remove redundant overlap data and skew position errors, to give a bit-mapped final image of the entire scanned item. Image compression is provided to compress the image into standard JPEG format for storage or transmission, or into facsimile format for transmission of the document to any fax machine. Optical character recognition (OCR) is provided to convert image data to text which may be sent as email, locally displayed, stored for later use, or further processed. Further processing of text data includes language translation and text to speech conversion of either the original or translated text. The resulting speech audio can be heard locally or transmitted over the cellular network.
