1. A multimedia device, comprising:
- a first image sensor to acquire a first image;
a second image sensor to acquire a second image; 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 extracts the feature of the person in the second image based on the coordinate information, wherein;
the first and second image sensors have overlapping fields of view;
the coordinate information provides an indication of a distance to the person, andthe processor compares the extracted feature to reference information and recognizes the person based on the comparison.
