Image squeezing circuit for squeezing ordinary-sized image into smaller area
 An image squeezing circuit produces an output image carrying signal for reproducing a small-sized image 1/m times larger than an ordinary-sized image (where m is an integer not less than two), and an input image carrying signal is separated for producing an analog chrominance subcarrier signal, an analog luminance signal and a color subcarrier signal, wherein the analog luminance signal is sampled with a sampling signal n/m times larger in frequency than the color subcarrier signal (where n is an integer not less than three) for producing a decimated digital luminance signal but the analog chrominance subcarrier signal is sampled with another sampling signal n times larger in frequency than the color subcarrier signal in every m pulse intervals of the color subcarrier signal for producing a decimated digital chrominance signal, the decimated digital luminance signal and the decimated digital chrominance signal being supplied to respective digital-to-analog converting circuits in response to a high frequency pulse signal n times larger in frequency than the color subcarrier signal for producing the output image carrying signal.
