ABSTRACT:
This document relates to an apparatus and method for controlling a camera according to temperature. The apparatus according to an embodiment of this document may comprise a camera comprising lenses comprising a focus lens, an iris, a lens barrel, a motor drive for controlling positions of the lenses and the iris, and a CCD, a temperature sensor for measuring a temperature of the camera, memory for storing information about a relationship between temperatures and positions of the lenses, and a state of the camera, and a controller for controlling the camera to capture an image, measuring temperature variation between a current state and a previous state through the temperature sensor, calculating a position where the focus lens has been moved according to the temperature variation based on the relationship information of the temperatures and the positions of the lenses, and determining whether to compensate for the moved position.
