Abstract
Miniature projection devices will enable the use of common household objects as the projection screen for still and moving images. This application describes a set of techniques and embodiments for implementing image projection inside a lamp such as a table or wall lamp and provides techniques for dealing with the unique physical attributes of lamps such as the shape of the lamp and the bright source of light that would tend to wash out the projected image. In addition, the invention presents a series of novel embodiments that respond changes in the environment to enable an immersive user experience and operation as a pet entertainment device.
