ABSTRACT:
An image processing apparatus includes a feedback unit configured to perform first nonlinear conversion of a signal obtained by subtracting a value of a subtraction image signal from that of a current-frame image signal, and to obtain the next subtraction signal by subtracting a signal obtained by performing the first nonlinearly conversion from the current-frame image signal, and a noise reduction unit configured to perform second nonlinear conversion of a signal obtained by subtracting a value of the subtraction image signal from that of the current-frame image signal, and to obtain an output image signal by subtracting a signal obtained by performing the second nonlinear from the current-frame image signal.
