Claim One:
1. An signal processing device, comprising: a decorrelation circuit configured to receive a plurality of initial scan line signals and to perform a decorrelation operation on the plurality of initial scan line signals to generate a plurality of decorrelated scan line signals; a plurality of wavelet decomposition circuits coupled to the decorrelation circuit and configured to perform wavelet decomposition operations on the plurality of decorrelated scan line signals to generate a plurality of decomposed scan line signals; a plurality of quantization circuits coupled to the plurality of wavelet decomposition circuits and configured to perform quantization operations on the plurality of decomposed scan line signals to generate a plurality of quantized scan line signals; and a bit multiplexer coupled to the plurality of quantization circuits and configured to generate a compressed bit stream based on the plurality of quantized scan line signals.
