Digital video camera non-integer-ratio Bayer domain scaler

摘要

An apparatus having a buffer and a circuit is disclosed. The buffer may be configured to receive a digital image. The digital image generally has (i) a Bayer color representation and (ii) two initial dimensions in a horizontal direction and a vertical direction respectively. The circuit may be configured to generate a resample image in a signal by down-sampling the digital image in the Bayer color representation such that (i) the resample image has two resample dimensions, (ii) at least one of the resample dimensions is smaller than a respective at least one of the initial dimensions and (iii) the respective at least one initial dimension is a non-integer multiple of the at least one resample dimension.
