Say, the color of project content word can be adjusted to white and/or, the dark-grey chromatic graph that project content can be included
The color parameter of piece is adjusted to the random color parameter in addition to Dark grey, avoids because the color of at least part project content is joined
Number is identical with the color parameter on perspective plane, the problem of being overlapped and can't see project content occurs.
For example, original projection content includes the word and icon of a variety of colors, electronic equipment (projecting apparatus) determines to throw
Word in project content is after Dark grey, with reference to Fig. 5, then can be adjusted to white, by project content by the color in shadow face
In color corresponding with the icon of perspective plane same color be adjusted to color other than Dark grey, other is not the figure of Dark grey
Mark then remains unchanged, wherein, game configuration and the corresponding Icon Color of download are identical with the color on perspective plane, are Dark grey,
Therefore, the corresponding Icon Color of game configuration can be adjusted to white, corresponding Icon Color will be downloaded and be adjusted to light grey,
The random color that can also be adjusted to other than other non-Dark greys.
