Table 3-79 describes the write parameters.
Parameter Bytes | Description |
---|---|
Byte 1 | Projection pitch angle (LSByte) |
Byte 2 | Projection pitch angle (MSByte) |
Default: 0000h
Table 3-80 shows the bit order and weighting for the two’s complement projection pitch angle data.
b15 | b14 | b13 | b12 | b11 | b10 | b9 | b8 | b7 | b6 | b5 | b4 | b3 | b2 | b1 | b0 |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 2–1 | 2–2 | 2–3 | 2–4 | 2–5 | 2–6 | 2–7 | 2–8 |
This command is used in conjunction with the Write Keystone Correction Control command.
The projection pitch angle is limited to the solution space in Table 3-81 for QnHD. Figure 3-18 shows examples of the projection pitch angle.
Throw Ratio Range | 0.2 to 0.4 | 0.4 to 0.6 | 0.6 to 0.8 | 0.8 to 1.0 | 1.0 to 2.0 | 1.0 to 1.2 | 1.2 to 2.0 |
---|---|---|---|---|---|---|---|
Max Pitch | -40 | -40 | -40 | -40 | -40 | -40 | -40 |
Min Pitch | 15 | 25 | 40 | 40 | 40 | 40 | 40 |
