Abstract: An image signal processor includes a register and a disparity correction unit. The register stores disparity data obtained from a pattern image data that an image senor generates, and the image sensor includes a plurality of pixels, and each of the pixel includes at least a first photoelectric conversion element and a second photoelectric conversion element. The image sensor generates the pattern image data in response to a pattern image located at a first distance from the image sensor. The disparity correction unit corrects a disparity distortion of an image data based on the disparity data to generate a result image data, and the image senor generates the image data by capturing an object.

Abstract: A communication method and terminal assist hearing and speech impaired persons. The communication method includes generating a text by combining at least one character input in a text call mode. The text is converted to a speech, and the converted speech is transmitted to a counterparty terminal. The communication terminal of the present invention is capable of converting the text input by the user to a speech signal for the counterparty terminal and converting the speech signal received from the counterparty terminal to a text such that it is possible for the user to conduct a communication with the counterparty regardless of whether the counterparty is a hearing or speech impaired or whether the counterparty's terminal supports the text call service, resulting in reduction of the text call service implementation complexity and improvement of user convenience.
