Canon LV-S300 사용자 설명서

The distance from the projector lens to the screen, the zoom setting (if available), and the video format 

each factors in the projected image size.
4:3 is the native aspect ratio of LV-S300/LV-X300. To be able to project a complete 16:9 (widescreen) 

aspect ratio image, the projector can resize and scale a widescreen image to the projector's native aspect 

width. This will result in a proportionally smaller height equivalent to 75% of the projector's native aspect 

height.

Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed by this 

projector. This will be seen as darkened (unlit) bars along the top and bottom (vertical 12.5% height 

respectively) of the 4:3 projection display area whenever displaying a scaled 16:9 aspect image in the 

vertical center of the 4:3 projection display area.
16:10 is the native aspect ratio of LV-WX300. To be able to project a complete 16:9 (widescreen) aspect 

ratio image, the projector can resize and scale a widescreen image to the projector's native aspect width. 

This will result in a proportionally smaller height equivalent to 90% of the projector's native aspect height.

Thus, a 16:9 aspect image will not utilize 10% of the height of a 16:10 aspect image displayed by this 

projector. This will be seen as darkened (unlit) bars along the top and bottom (vertical 5% height 

respectively) of the 16:10 projection display area whenever displaying a scaled 16:9 aspect image in the 

vertical center of the 16:10 projection display area.
The projector should always be placed horizontally level (like flat on a table), and positioned directly 

perpendicular (90° right-angle square) to the horizontal center of the screen. This prevents image 

distortion caused by angled projections (or projecting onto angled surfaces). 
The modern digital projector does not project directly forward (like older style reel-to-reel film projectors 

did). Instead, digital projectors are designed to project at a slightly upward angle above the horizontal 

plane of the projector. This is so that they can be readily placed on a table and will project forward and 

upwards onto a screen positioned so that the bottom edge of the screen is above the level of the table (and 

everyone in the room can see the screen).
You can see from the diagram on page 

, that this type of projection causes the bottom edge of the 

projected image to be vertically offset from the horizontal plane of the projector.
If the projector is positioned further away from the screen, the projected image size increases, and the 

vertical offset also increases proportionately.
When determining the position of the screen and projector, you will need to account for both the projected 

image size and the vertical offset dimension, which are directly proportional to the projection distance.

This is due to interference with the screen surface and is not a mal-function. Replace the screen or 

displace the focus a little.
