Abstract
A projection method includes detecting a first distance between a projector and a first portion of a projection surface, detecting a second distance between the projector and a second portion of the projection surface, detecting a third distance between the projector and a third portion of the projection surface, projecting image light in a first visual aspect according to the first distance onto the first portion by using the projector, projecting image light in a second visual aspect according to the second distance onto the second portion by using the projector, and projecting image light in a third visual aspect based on the first and second visual aspects onto the third portion by using the projector when the third distance is longer than the first distance but shorter than the second distance.
