Abstract
Embodiments relate to a first demosaicing circuit and a second demosaicing circuit that can perform demosaicing of image data. The first demosaicing circuit processes received image data to generate a first demosaiced image for obtaining statistic information on the received image data. The second demosaicing circuit performs demosaicing of the received image data to generate a second demosaiced image. A processing circuit pipeline performs at least one of resampling, noise processing, color processing and output rescaling performed on the second demosaiced image based on the statistics information obtained from the first demosaiced image.
Claims20
An apparatus for processing image signal data, comprising:
- a first demosaicing circuit configured to process a received image data to generate a first demosaiced image for obtaining statistics information on the received image data;
- a second demosaicing circuit configured to perform demosaicing of the received image data to generate a second demosaiced image;
- and
- a processing circuit pipeline configured to perform at least one of resampling, noise processing, color processing and output rescaling on the second demosaiced image based on the statistics information obtained from the first demosaiced image.
A method of demosaicing image data from an image sensor, comprising:
- processing, by a first demosaicing circuit, a received image data to generate a first demosaiced image for obtaining statistics information on the received image data;
- performing, by a second demosaicing circuit, demosaicing of the received image data to generate a second demosaiced image;
- and
- performing, by a processing circuit pipeline, at least one of resampling, noise processing, color processing and output rescaling on the second demosaiced image based on the statistics information obtained from the first demosaiced image.
An electronic device, comprising:
- an image sensor configured to generate image data;
- a first demosaicing circuit configured to receive the image data and process the received image data to generate a first demosaiced image for obtaining statistics information on the received image data;
- a second demosaicing circuit configured to perform demosaicing of the received image data to generate a second demosaiced image;
- and
- a processing circuit pipeline configured to perform at least one of resampling, noise processing, color processing and output rescaling on the second demosaiced image based on the statistics information obtained from the first demosaiced image.
