In an image sensing an processing device, a movement vector of an image is detected in each of detection blocks formed by dividing an image sensing plane, and a distributed state of the image movement within the image sensing plane is detected by statistically processing the movement vector detected in each of the detection blocks. On the basis of the distributed state of the image movement, an area having an image of a main photographed object is detected so as to set a focus detecting area on the image sensing plane or to control a focusing circuit.
