Signal processing producing interpolated signal values in an image signal


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.

Image communication apparatus and signal processing unit


This image communication apparatus receives a digital signal having a voice bandwidth from an external apparatus capable of communicating through a network, and processes the received digital signal by means of a signal processing unit. If it is determined that the digital signal includes a cng signal, the image communication apparatus determines that the digital signal is a facsimile signal received as deemed voice, and executes facsimile reception according to the t.30 standard.
