Abstract:
An apparatus having a first circuit is disclosed. The first circuit may (i) receive an input signal from an electro-optical sensor and (ii) generate a compressed signal. The first circuit generally includes re-sampler circuits configured to process the input signal to generate output samples. Each output sample may be a linear combination of at least two input samples. Video processing may include at least two tasks among (a) generating a video signal by converting the input signal for an external video monitor, (b) generating a video signal by converting the input signal for a preview screen and (c) generating a video signal by resolution reduction of the input signal before compression. At least two re-sampler circuits may perform different tasks. Still processing generally includes a noise reduction of an input image of the input signal using at least one of the at least two re-sampler circuits.
