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.
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
,
minimized and aligned with
controlling signals. Important internal synchronization signals include H_cnt, V_cnt, internal blank, and
end_of_fram
e
s.
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
is
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.
