Abstract
A method comprises: detecting a first parameter of the projection area with respect to the projection unit; obtaining a second parameter of the projection unit; determining a third parameter and a fourth parameter of the projection area and first attribute information of the one or more display objects, according to the first parameter and the second parameter; judging whether the first attribute information of the one or more display objects satisfies a predetermined first presentation requirement, so as to generate a first judgment result; adjusting the first attribute information of the one or more display objects to second attribute information, if the first judgment result indicates that the first attribute information of the one or more display objects does not satisfy the first presentation requirement. The present invention improve display effects of certain display objects by changing the display parameters of the display objects, in order to achieve an effect of clearly displaying respective display objects.
