Abstract
The signal processing method of the present invention produces interpolated signal values in an image signal by an inverse discrete cosine transformation with a set of frequency coefficients by decreasing an interval for reproduction of pixel signal values, wherein a set of frequency coefficients is provided by a discrete cosine transformation and is compensated for the frequency response caused by dividing pixels. According to the invention, an image signal similar to that obtained with a solid-state imaging device constructed by divided pixels is provided. Hence, even when the number of horizontal pixels and/or the number of vertical pixels of the solid-state imaging device are a half of that of a display apparatus used, an image signal suitable to the display apparatus can be produced.
