A multimedia device having multiple image sensors, comprising: a first image sensor (304, 423, 524) to acquire a first image, wherein the first image sensor corresponds to a camera for sensing depth data; a second image sensor (305, 424, 525) to acquire a second image, wherein the second image sensor corresponds to a camera for sensing color data, and the second image sensor is physically detached from the first image sensor; a memory to store at least one of multimedia function mapped with each of persons; and a processor to detect a person in the first image and to extract a feature of the person from the second image, wherein the processor determines coordinate information of the person in the first image, and the coordinate information provides an indication of a first distance to the person, further the processor adjusts 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, sends a signal to the second image sensor based on the adjusted value, and extracts the feature of the person in the second image based on the coordinate information and the adjusted value, wherein: the first and second image sensors have overlapping fields of view; and the processor compares the extracted feature to reference information and recognizes the person based on the comparison, further performs a specific multimedia function corresponding to the recognized person, characterized in that if the first distance acquired by the operation of the first image sensor between the user and the first image sensor is less than a first reference value, or if a recognition rate on the face of the user, which is acquired by the operation of the first image sensor, is more than a second reference value, the processor detects and recognizes the face of the user by the first image sensor without the second image sensor, if the first distance exceeds the first reference value, or if the recognition rate on the face of the user is less than the second value, the processor detects and recognizes the face of the user by both of the first image sensor and the second image sensor. a first image sensor (304, 423, 524) to acquire a first image, wherein the first image sensor corresponds to a camera for sensing depth data;
