What is the purpose of demosaicing?

Goal. The aim of a demosaicing algorithm is to reconstruct a full color image (i.e. a full set of color triples) from the spatially undersampled color channels output from the CFA.

What is de Bayer?

The DeBayer filter is used to convert raw image data into an RGB image. In a raw color image, every pixel represents a value for one basic color, instead of three as is the case for an RGB image. In order to get a real color image, the two missing colors have to be interpolated. This is exactly what this filter does.

What are CFA images?

In digital imaging, a color filter array (CFA), or color filter mosaic (CFM), is a mosaic of tiny color filters placed over the pixel sensors of an image sensor to capture color information.

Are photosites pixels?

Three photosites are dedicated for each pixel. A Bayer uses one photosite for each pixel, and a colored filter in front of the photosite. If the color filter passes blue, then that pixel receives blue light only. The neighbor pixel/photosite has a red filter….Latest buying guides.

What is de-bayering in cameras?

Classic 3-chip camera design with a prism to split the image into the three colour primaries. De-Bayering is one of the the first steps of digital image processing of a raw image. Back in the old days, most (broadcast) video cameras with CCD image sensors had three sensors, one for each colour: Red, Green, Blue (R,G,B).

Do I need to Debay my camera?

Note: Debaying is required for any output from any colour camera sensor when used in RAW mode. This article applies to deepsky images (.FITS format) and for solar system/planetary videos (.SER format). Firstly, what is Debayering? Colour CMOS camera sensors usually have four colour channels (two greens, one red and one blue).

What is Dede-bayering?

De-Bayering is one of the the first steps of digital image processing of a raw image. Back in the old days, most (broadcast) video cameras with CCD image sensors had three sensors, one for each colour: Red, Green, Blue (R,G,B).

How do I debayer images from the HyperCam 183C?

Take an image with the Hypercam 183C in RAW mode. To debayer it correctly in PixInsight, you must select RGGB, but in AstroArt you have to select GBRG. This is because .FITS files are read starting bottom left instead of top left for most image files.
