An image signal output from a CCD is input to an edge emphasis adjusting unit. A scene determining unit determines a scene of an image to be processed on the basis of an operation of selecting a shooting mode or the like. A tone characteristic control unit performs a control of selecting a tone characteristic used in a tone converting unit for edge emphasis on the basis of the scene determination result. A plurality of tone characteristics for edge emphasis are prepared, and have different luminance ranges in which a .gamma. value changes. After the tone converting process for edge emphasis, an edge emphasizing process is performed by an edge emphasizing unit, and the tone conversion according to the monitor characteristic is performed in a tone converting unit for correction.
