According to the image taking apparatus and the method of controlling an edge enhancing level of an original image signal, as the electronic zooming rate for the original image signal increases, an amplitude level of the edge signal decreases in a direction contrary to the increase of the electronic zooming rate, and thereby, an edge enhancing level of the edge-enhanced image signal is automatically suppressed. Accordingly, even though zooming processing is applied to the edge-enhanced image signal, it is able to obtain an enlarged image signal having natural edges by suppressing excess enlargement of the edge signal added to the original image signal.
