Abstract
A system and method for processing mosaiced or raw data images operates to concurrently demosaic and resize the mosaiced images in a combined process. The combined demosaic/resize process allows the system to perform demosaicing and resizing more efficiently than conventional systems, which perform these processes separately and sequentially. Furthermore, the combined demosaic/resize process allows the system to produce demosaiced and resized images of higher quality as compared to demosaiced and resized images produced by the conventional systems.
Claims25
A method of demosaicing and resizing a mosaiced image comprising:
- receiving a current image block of said mosaiced image;
- computing an indicator of said current image block based on color data of said current image block;
- and
- generating a resized image block from said current image block of said mosaiced images in response to said indicator to produce a resized image of said mosaiced image, including embedding selected color information from said current image block of said mosaiced image into said resized image block such that said resized image of said mosaiced image is demosaiced.
A system for demosaicing and resizing a mosaiced image comprising:
- an image processing module that receives a current image block of said mosaiced image, said image processing module being configured to generate a resized image block from said current image block of said mosaiced image to produce a resized image of said mosaiced image, said image processing module including:
- an indicator computer that is configured to compute an indicator of said current image block based on color data of said current image block;
- and
- a color inserter that is configured to embed selected color information from said current image block of said mosaiced image into said resized image block in response to said indicator such that said resized image of said mosaiced image is demosaiced.
A method demosaicing and resizing a mosaiced image comprising:
- receiving a current image block of said mosaiced image;
- computing an indicator of said current image block based on color data of said current image block;
- comparing said indicator to a threshold;
- dividing said current image block to derive a new current image block of said mosaiced image when said indicator meets a predefined criterion with respect to said threshold;
- and
- generating a pixel from said current image block of said mosaiced images when said indicator does not meet said predefined criterion with respect to said threshold to produce a resized image of said mosaiced image, including embedding selected color information from said current image block of said mosaiced image into said pixel such that said resized image of said mosaiced image is demosaiced.
