Tuning the CSC Feature

The CSC submodule performs YUV-to-RGB conversion based on the coefficients and offsets specified in the table as follows:

$\left[\begin{array}{c}\mathrm{R}\\ \mathrm{G}\\ \mathrm{B}\end{array}\right]=\left[\begin{array}{ccc}{\mathrm{coef00}}_{\mathrm{y2r}}& {\mathrm{coef01}}_{\mathrm{y2r}}& {\mathrm{coef02}}_{\mathrm{y2r}}\\ {\mathrm{coef10}}_{\mathrm{y2r}}& {\mathrm{coef11}}_{\mathrm{y2r}}& {\mathrm{coef12}}_{\mathrm{y2r}}\\ {\mathrm{coef20}}_{\mathrm{y2r}}& {\mathrm{coef21}}_{\mathrm{y2r}}& {\mathrm{coef22}}_{\mathrm{y2r}}\end{array}\right]\left(\right[\begin{array}{c}\mathrm{Y}\\ \mathrm{U}\\ \mathrm{V}\end{array}]-[\begin{array}{c}{\mathrm{offset0}}_{\mathrm{y2r}}\\ {\mathrm{offset1}}_{\mathrm{y2r}}\\ {\mathrm{offset2}}_{\mathrm{y2r}}\end{array}\left]\right)$

You can use one of the following methods to update the YUV2RGB Coef table:

• Double-click and edit a cell in the table to update a single value.
• Click Edit and update the values in the prompted Edit Table dialog.

  The values must be specified in the same order as the table columns and separated by a comma (,).

• Click Export to export the values to a .csv file, edit the file, and then import the updated values from the .csv file.

  The order of the values in the exported .csv file is the same as that in the table.

The CSC submodule performs RGB-to-YUV conversion based on the coefficients and offsets specified in the table as follows:

$\left[\begin{array}{c}\mathrm{Y}\\ \mathrm{U}\\ \mathrm{V}\end{array}\right]=\left[\begin{array}{ccc}{\mathrm{coef00}}_{\mathrm{r2y}}& {\mathrm{coef01}}_{\mathrm{r2y}}& {\mathrm{coef02}}_{\mathrm{r2y}}\\ {\mathrm{coef10}}_{\mathrm{r2y}}& {\mathrm{coef11}}_{\mathrm{r2y}}& {\mathrm{coef12}}_{\mathrm{r2y}}\\ {\mathrm{coef20}}_{\mathrm{r2y}}& {\mathrm{coef21}}_{\mathrm{r2y}}& {\mathrm{coef22}}_{\mathrm{r2y}}\end{array}\right]\left(\right[\begin{array}{c}\mathrm{R}\\ \mathrm{G}\\ \mathrm{B}\end{array}]-[\begin{array}{c}{\mathrm{offset0}}_{\mathrm{r2y}}\\ {\mathrm{offset1}}_{\mathrm{r2y}}\\ {\mathrm{offset2}}_{\mathrm{r2y}}\end{array}\left]\right)$

The methods of updating the RGB2YUV Coef table are similar to those of updating the YUV2RGB Coef table described in Step 1.
