52.6.10 Color Space Conversion (CSC) Module
By converting an image from RGB to YCbCr color space, it is possible to separate Y, Cb and Cr information. The CSC samples the gam_data[29:0] 30-bit data bus, extracts YCbCr information from the sampled data, and then generates the color-converted data csc_data[29:0] and the validity signal csc_valid.
| ISC_CSC_CTRL.ENABLE | CSC_DATA Slice | Value |
|---|---|---|
| 0 | csc_data[29:0] | gam_data[29:0] |
| 1 | csc_data[29:20] | Y = clipped(sum(gam_data_x * gain_Yx) + offset_y << 2) |
| csc_data[19:10] | Cb = clipped(sum(gam_data_x * gain_Cbx)+offset_cb << 2) | |
| csc_data[9:0] | Cr = clipped(sum(gam_data_x * gain_Crx)+offset_cr << 2) |
