Abstract:
An image pickup apparatus comprising:luminance signal extracting means for extracting a luminance signal from an image pickup signal photographed by a solid state image pickup device; filter means for extracting at least a high frequency component in said luminance signal extracted by said luminance signal extracting means; gain control means for varying a gain of at least said high frequency component in said luminance signal extracted by said filter means; outline emphasizing means for emphasizing an edge portion by adding said luminance signal from said luminance signal extracting means and at least said high frequency component in said luminance signal in which the gain has been varied by said gain control means; and control means for controlling an in-focus point by driving a focusing lens on the basis of a level of at least said high frequency component in the luminance signal extracted by said filter means, wherein the image pickup signal photographed by said solid state image pickup device is processed.
