Abstract:
An image signal encoding apparatus for providing an encoded signal comprising:an input terminal for receiving a first image signal having a high resolution; motion vector detecting means, coupled to the input terminal, of detecting motion vectors in the first image signal; resolution reducing means, coupled to the input terminal, of forming a second image signal having a low resolution from said first image signal; image signal interpolating means, coupled to the resolution reducing means, of interpolating said second image signal to form an interpolated signal having a number of pixels the same as a number of pixels in the first image signal; differential means, coupled to the motion vector detecting means and the image signal interpolating means, of determining a differential between said first image signal and said interpolated signal to form a differential signal; an encoding means of using said motion vectors to low-efficiency-encode said differential signal and form an encoded signal; and an output terminal, coupled to the encoding means, for providing the encoded signal.
