*This distance is especially recom- mended for
NOTE:
Values shown are approximate. The value for L (distance to screen) varies slightly depending on the zoom lens characteris- tics.
When the shortest projection distance is used, a small amount of distortion may occur in the image due to the zoom lens characteristics.
The value for H (the height from the edge of the screen to the centre of the lens) is the value when the horizontal optical axis shift function is not used. The value decreases when the horizontal optical axis shift function is used. For details, see Shift range on page 7.
Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 4:3 |
|
|
|
|
minimum | L (m) = (diagonal screen size in inches) x | 0.0305 | - | 0.049 |
maximum | L (m) = (diagonal screen size in inches) x | 0.0604 | - | 0.050 |
NOTE:
Distances calculated with the above equations will include a slight error.
