IMAGE PROCESSING DEVICE

An object of the present invention is to provide an image processing device capable of reducing a change frequency of a processing unit with respect to a temperature change of a lens of the image processing device. An image processing device according to the present invention acquires a temperature difference between a first temperature of a first camera and a second temperature of a second camera, and outputs a result of first processing if the temperature difference falls within a reference range, and performs second processing different from the first processing instead of or together with the outputting of the result of the first processing if the temperature difference does not fall within the reference range (see FIG. 2 ).
