Abstract
The specification and drawings present a new method, apparatus and software product for image binning (downscaling) according to a predetermined procedure for a pre-selected color arrangement (e.g., a Bayer arrangement) by substantially maintaining a phase of channels (represented by selected colors) for reducing/elimination of artifacts in images taken by an electronic device. Several binning or scaling modes where the center points of each binned (e.g., averaged) pixel are arranged in the pre-selected color arrangement and maintain the phase of the channels are described.
Claims35
An apparatus, comprising:
- a binning processor, configured to perform binning of a plurality of pixels with a pre-selected color arrangement comprised in an image using a predetermined procedure, wherein
- center points of binned pixels, representing said image and formed by said binning, maintain said pre-selected color arrangement,
- distances between any two adjacent center points of said center points are substantially equal in at least one direction, vertical or horizontal, and
- said binned pixels are for further
The apparatus of claim 35, wherein said image sensor is a charged-coupled device or a complimentary metal oxide semiconductor sensor.
The apparatus of claim 35, wherein said image sensor and the binning processor are combined in one module.
A method, comprising:
- binning a plurality of pixels with a pre-selected color arrangement comprised in an image using a predetermined procedure, wherein
- center points of binned pixels, representing said image and formed by said binning, maintain said pre-selected color arrangement,
- distances between any two adjacent center points of said center points are substantially equal in at least one direction, vertical or horizontal, and
- said binned pixels are for further processing of said image.
A module, comprising:
- a binning processor, configured to response to an image signal comprising information on a plurality of pixels with a pre-selected color arrangement comprised in an image, configured to perform binning of said plurality of pixels using a predetermined procedure, wherein
- center points of binned pixels, representing said image and formed by said binning, maintain said pre-selected color arrangement,
- distances between any two adjacent center points of said center points are substantially equal in at least one direction, vertical or horizontal, and
- said binned pixels are for further processing of said image.
