Abstract
A signal processing device that processes sharpening of an image with respect to an input signal (SR) that represents the image and outputs an output signal (SO) that represents the sharpened image includes an oversampler that generates an oversampled signal by interpolating a signal in order to increase a sampling frequency with respect to an input signal (SR), and a sharpening processing unit to which the oversampled signal is inputted and which generates a sharpened signal in which high frequency band components in the oversampled signal are nonlinearly monotonically increased in a broad sense, and the sharpened signal is outputted as the output signal (SO).
