In maximum color calibration, the pixel which has the maximum color component (based on
CRB1[3:0]) can be found. In color read back calibration, the color component (based on
CRB[3:0]) for specific position can be read back. In maximum color difference calibration, for
specific color component, color differences between every 2 neighboring pixels are compared
from first till the last pair within a frame. The position which has the largest color difference
with its neighboring data is found.
Phase calibration can report pixel mismatch in up to 32 frames based on 2 specified points.
FIG3-4 Capture Controller block
YUV to RGB Block
This block performs color space format conversion. Mascot V can convert 16 Bit YUV, RGB
into 24 Bit RGB data format.
Scaling Down
This block is used to conditionally drop incoming data if the incoming resolution greater than
1024x768 which is the physical resolution of the panel. A modified version of the Bresenham
line-drawing algorithm is used to determine which incoming data not to discard.

Capture Controller
Capture Controller is used to generate synchronization signals which are used for
internal Mascot V. Within Capture Controller block(FIG3-4), incoming data are
processed, filtered and minimized and aligned with controlling signals. Important
internal synchronization signals include H_cnt, V_cnt, internal blank, and end_of_frame.
