摘要

In an image data conversion unit, image quality can be further improved as compared with a conventional unit. Prediction data are generated from teacher image data (HD) corresponding to second image data by using a plurality of filters (F1 to F4) having pass-bands different from each other and thereby, the second image data can be generated by using prediction data corresponding to characteristics of first image data, which enables further improvement of image quality as compared with a conventional case. <IMAGE>
