1. A method for managing information in a television having multiple image sensors, comprising: acquiring a first image in a first image sensor; acquiring a second image in a second image sensor, wherein the second image sensor is physically detached from the first image sensor; detecting a person in the first image; determining coordinate information of the person in the first image, wherein the coordinate information provides an indication of a first distance from the first image sensor to the person; adjusting at least one value corresponding to the person in the first image based on a second distance between the first image sensor and the second image sensor, wherein a physical location of the first image sensor is different from a physical location of the second image sensor, and at least one of the first image sensor or the second image sensor is movable; sending a signal to the second image sensor based on the adjusted value; extracting a feature of the person from the second image based on the coordinate information and the adjusted value; comparing the extracted feature to reference information; recognizing the person based on the comparison of the extracted feature to the reference information; displaying the recognized person's information while continuing to display a program received via a broadcast network when the person is recognized based on the comparison; displaying a guide message for registering a non-recognized person while continuing to display a program received via a broadcast network when the person is not recognized based on the comparison, wherein a registered identification (ID) information is coupled with graphic data acquired by the first image sensor or the second image sensor selectively; and storing the registered ID information with the coupled graphic data in a database of the television.
