1. An image signal processing device, comprising:
circuitry configured to:
obtain an input signal of an image;
determine whether the input signal represents:
a first signal of a first domain having first signal characteristics, wherein the first signal is learned to obtain a, learning result for quality improvement processing, or
a second signal of a second domain having second signal characteristics different from the first signal characteristics, wherein the second signal is unknown data for a learning result of the input signal
apply, based on a determination that the input signal represents the first signal, the quality improvement processing to the input signal to obtain an output signal, wherein the output signal is obtained based on the learning result from the first signal; and
update, based on a determination that the input signal represents the second signal, the learning result associated with the second signal based on the second signal such that the quality improvement processing corresponds to the second signal,
wherein the update of the learning result uses as teacher data for the second signal, data which was used as student data for the first signal during learning of the quality improvement processing.
