Abstract
In an image data compression method, digitized luminance (Yin) and chrominance (Uin, Vin) signal samples in a ratio yin:uin:vin are subsampled (IDC) to obtain subsampled luminance (Yout) and chrominance (Uout, Vout) signal samples in a ratio yout:uout:vout, wherein yin:yout exceeds uin:uout and/or yin:yout exceeds vin:vout.
