Abstract
An image signal transmitting system which comprises a first field offset sub-sampling circuit for processing a first image signal as a still image, the first image signal being in a relatively lower region of temporal motion frequency in a motion frequency band, a frame/line offset sub-sampling circuit for processing the first image signal, a line offset sub-sampling circuit for processing a second image signal as a moving image, the second image signal being in a relatively higher region of temporal motion frequency in the motion frequency band, a second field offset sub-sampling circuit for processing a third image signal, the third image signal being a middle region of temporal motion frequency in the motion frequency band between the lower temporal frequency region and the higher temporal frequency region, whereby the third image signal is sub-sampled only by the second field offset sub-sampling circuit, and each of the sub-sampling circuits has the same sampling points for the first, second and third image signals.
