<P>PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of determining a gradation region based on an image signal to be input to selectively smooth an image signal, and converting the smoothed image signal into an image signal with larger number of gradations than that of the image signal to be input, and to provide an image processing method, a program, and a display device. <P>SOLUTION: The image processing apparatus includes: a frequency component detection unit which detects signals of a predetermined frequency band from N bits (N is a positive integer) of input image signals for every pixel; a detected value smoothing unit which spatially smoothes detection signals corresponding to the respective pixels detected by the frequency component detection unit, respectively; a control signal generation unit which generates, for every pixel, control signals for regulating the gradation region based on the smoothed detection signals; and a gradation number extension which outputs N+k bits (k is a positive integer) of first output image signals, in which the number of gradations of the input image signal is extended by the predetermined number based on the control signals, or N+k bits of second output image signals, in which the input image signal is smoothed temporally and the number of gradations is extended by the predetermined number, for every pixel. <P>COPYRIGHT: (C)2011,JPO&INPIT |
