   * **YUV color profiles**: all the three profiles **Default**, **SJCAM - Vivid** and **Flat** are made equals and neutral; multiplier is 1 and offset is zero for all the three Y, U and V components (shoul be actually Y, Cb and Cr when treating digital signals).   * **YUV color profiles**: all the three profiles **Default**, **SJCAM - Vivid** and **Flat** are made equals and neutral; multiplier is 1 and offset is zero for all the three Y, U and V components (shoul be actually Y, Cb and Cr when treating digital signals).

   * Changed **gamma curves**: added some brightness to shadows with an overall gamma coefficient of 1.10 and removed a slight red casting when using Auto White Balance in early hours of sunny days. All the gamma tables for video modes are the same, for photo modes we leaved a linear gamma (1.0) for R, G and B.   * Changed **gamma curves**: added some brightness to shadows with an overall gamma coefficient of 1.10 and removed a slight red casting when using Auto White Balance in early hours of sunny days.
