Post-Processing

The video camera utilizes a single image sensor for the three primary colors red, green, and blue. For this reason the image sensor is covered by an array of color filters, also referred to as Bayer filter mosaic. Image sequences were captured in raw format first. Then each single image was post-processed as follows.

The single post-processing steps are illustrated below.

Input:   The raw image

 

Step 1:   Bayer demosaicing

Step 2:   Vignetting removal

Step 3:   White balance correction

Step 4:   Image compression
