Abstract
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.

An apparatus comprising:
- a buffer configured to receive a digital image, said digital image having (i) a Bayer color representation, (ii) a first initial dimension in a horizontal direction and (iii) a second initial dimension in a vertical direction;
- and
- a circuit configured to generate a resample image from said digital image in said Bayer color representation such that (i) said resample image has two resample dimensions, (ii) at least one of said two resample dimensions is smaller than a respective one of said first and said second initial dimensions and (iii) said respective one of said first and said second initial dimensions is a non-integer multiple of said at least one resample dimension.
An apparatus comprising:
- a buffer configured to receive a digital image, said digital image having (i) a Bayer color representation, (ii) a first initial dimension in a horizontal direction and (iii) a second initial dimension in a vertical direction;
- and
- a circuit configured to generate a resample image from said digital image in said Bayer color representation such that (i) said resample image has two resample dimensions, (ii) at least one of said two resample dimensions is smaller than a respective one of said first and said second initial dimensions and (iii) a sample in said digital image is used to generate two samples in said resample image.
An apparatus comprising:
- a buffer configured to receive a digital image, said digital image having (i) a Bayer color representation, (ii) a first initial dimension in a horizontal direction and (iii) a second initial dimension in a vertical direction;
- and
- a circuit configured to generate a resample image from said digital image in said Bayer color representation such that (i) said resample image has two resample dimensions, (ii) at least one of said two resample dimensions is smaller than a respective one of said first and said second initial dimensions and (iii) a first sample of said resample image is calculated as a non-averaging combination of a plurality of second samples in said digital image.
