Abstract: To obtain an excellent edge enhancement effect even when dynamic ? correction processing is executed for an edge-enhanced image signal, and to obtain an excellent edge enhancement effect for various ?-characteristics. An edge component is detected from an input image signal. A ? correction curve is calculated based on characteristics of an image scene detected by a scene characteristic detector, and its data is stored in a dynamic ? correction RAM table and an inverse gradient RAM table. A gain controller multiplies the edge component by a control signal from the inverse gradient RAM table to generate an edge enhancement signal which is in turn added to the image signal to obtain an edge-enhanced signal. The inverse gradient RAM table sends an inverse number of a gradient of a ? correction curve corresponding to a signal level of the inputted image signal as the control signal to the gain controller.
